Twilight whistled happily as she skipped down the stairs of the Royal Research Academy's Botany Division. Normally, only the ponies involved in ongoing research were allowed into the laboratory and containment section of the academy, even being the Princess’s student hadn’t gotten the young mare access. Today was different; Twilight had been granted official researcher status as part of a gift from the princess for her fourteenth birthday. She had already passed all of the requisite classes at that point any ways as well as the sixteen hours of safety briefing and now had access to the entirety of the vast academy as well as its tools and resources...as long as she used them responsibly.

With all of that responsibility in mind, Twilight was on her way to find something small to start her research with. Something to get her hooves wet as well as get used to the facilities. Botany didn’t normally hold that much interest for her, at least compared to things like astronomy and arcana, but when she stepped into the Flora Librarium her breath was stolen away.

Rows upon rows of hard wood shelves stretched across the massive room, each holding dozens of different plant species stored in magical stasis. Behind the shelves was a large open space filled with patches of different soil with several different plant specimen growing in them. The whole room was lit by the open glass ceiling and each soil patch had a plate of magical glass suspended above it, that could independently change the amount of light the patch got.

Twilight couldn’t help but hop from hoof to hoof as her eyes travelled from each row to the next. She started trotting along the outside of the shelves and peering down the aisles. With no clear destination in mind she was careful to mentally catalog each plant stored in the aisles. When she reached that last row however, all of the dormant plants were placed in cages. This was probably the most exciting part of the whole room and Twilight hummed happily as she started down the aisle.

All of the plants kept in this isle showed varying signs of mental awareness and had to be secured so that if the magical stasis wore off they didn’t try and run away, or in the case of the Logiticus Lotus and Argumentum Arborialis, argue incessantly and very loudly. These plant were the pride of the Flora Librarium and Twilight couldn’t wait to get her hooves on one of them, but which one?

She read each tag extensively in her search. The Logiticus Lotus sounded intriguing but according to the description, though it was able to hold highly intellectual discussions, its attitude was condescending and rude. The Berry Bombidaris also looked neat, the fruit perportedly being very tasty, but she wasn’t sure if she was ready to deal with the bush they grew on trying to literally shove the berries down her throat. Of course nothing in this area was truly dangerous, all of those plants were sealed off in the vault deeper in the Librarium along with the Black Lotus, Red Lotus, Orange Lotus and Green Pear, but Twilight still wanted something a bit more laid back to experiment with.

When she found the Aphromia Tentacus though she paused. The description was very short, reading only “Very Affectionate,” though some pony had taken red marker and added “I hate you Sun Gazer,” much to Twilight chagrin. Ponies should have more respect then to vandalize state property. Regardless, the plant seemed easy enough to deal with.

As Twilight undid the latch and carefully removed the large container housing the plant from the shelf a thick trottingham accent accosted her.

“I wouldn’t take that one is I were you,”

Twilight turned to see a beautiful white flower pointed at her and wrinkled into a frown.

“Oh what would you know?” a slightly foreign voice replied from a slowly shifting miniature tree.

“I know she doosn’t want any of that.” the lotus returned.

“Oh yeah, is that right?”

Twilight didn’t let the Argumentum Arborialis finish as she replaced the stasis spell on the two arguing plants before calmly walking away. Now that she had a subject, she just had to find a lab room and since it was saturday, a day most pony’s had found that they were allergic to working on, it didn’t take long.

The laboratory was a roughly ten foot by ten foot room with a patch of dirt in the middle and a skylight with various gardening tools lined up along the outer walls as well as a water line. Twilight placed the container on a counter off to the side and gingerly removed the top from it. Inside was a large open flower with a closed bud at its center.

Quickly, but smoothly, Twilight removed the flower from the container and began replanting it in the soil at the center of the room. Then with the utmost care, she removed the stasis spell from it. As time returned to the plant, the dull gray color of its petals turned a bright reddish bronze that faded to pink at the edges and the bud at the center became bright white.

Happy with the transplant, Twilight picked the information card up out of the container and began to go over the more detailed fact sheet. She stopped though when a whimpering sound came from the flower. Curious, Twilight carefully made her way over and leaned in to inspect the plant. When her nose got close to the bud, the Flower sprayed a fine pink mist into Twilight’s face, causing her to cough and wheeze as she stumbled away from the plant.

Twilight rushed over to the information card to see what she needed to do to protect herself, but where the card mentioned the mist, all it said was that the discharge was not dangerous in any way. With her fears assuaged, Twilight returned to the plant, not noticing that the room had gotten a little bit warmer. As she continued to inspect the plant, she noticed that the mist had left a sweet aroma in the air and as she took a deep breath of it a slight blush appeared on her face.

She didn’t waste too much time enjoying the fragrance however and began gently prodding the plant in order to elicit a response, she was a little disappointed as the smell of the flower faded though and more than a little excited when the flower, not in her face this time, released another spray of the pink mist. The amount that it sprayed out was far greater than before and the entire room took on it’s aroma.

Twilight was starting to notice her increased body heat, but figured that the room must just have been heating up as the day wore on. What she didn’t notice, was that she was unconsciously raising her tail up a little and partially exposing her marehood. She hummed merrily as she made observations while enjoying the pleasant atmosphere. Something about the fragrance made her excited and energetic and as she continued to work, the blush on her face became a deeper red. When she bent down to get a probe from beneath a counter, she instinctively flipped her tail to the side and pushed her butt into the air, exposing her pussy lips completely. When the slight breeze from the ventilation system blew over her moist marehood, Twilight sucked in a breath. She looked beneath her body and watched with rapt attention as a single drop of arousal fell from her nether lips.

The excitement of science had kept her distracted from it before but as Twilight accessed herself, she quickly wrapped her tail between her legs and backed herself into a corner of the room. She closed her eyes and took several deep breaths to calm herself. Twilight was not very experienced when it came to sex, she had only had her first heat last spring and even then had only pleasured herself reluctantly. She was well read on the biology of it of course, but that didn’t do her any good now.

She tried to clear her head of the encroaching desires but unlike her heat, which had been a battle between the needs of her body and her mental trepidation, she actually wanted to feel sexual stimulation now. Arousal and conscience clashed inside her head until she finally gave into her desires. Like anything else though, Twilight was not going to be caught unprepared. She trotted over to the door of the lab, rubbing her thighs together all the way, and put up the Testing in Progress flag.

None of the laboratories had locks due to safety concerns but it was a rule that unless it was an emergency, ponies were not allowed to interrupt experimentation in progress. With that done, Twilight sat down on the dirt patch in front of the flower and spread her legs apart. She wasn’t absolutely sure why, but being closer to the source of the amazing aroma made her feel better.

Twilight took a moment to look down at her exposed labia. Some young ponies thought that a pony’s private parts looked gross but Twilight had always thought that every part of a pony was a beautiful piece of biological artwork. She gently ran the tip of her hoof along her slit, gasping quietly as the parted slightly, allowing more of her liquid arousal to run free adding the slight smell of her own musk to the aroma in the air. With her other hoof, she gingerly pulled her nether lips apart before pushing the tip of her hoof into her passage. She moaned as the sensitive walls parted and gently pushed her hoof tip in a little deeper before massaging herself in a circular motion. Her movements were inexperienced and jerky but all the same, the sensation and pressure began to build inside her. Twilight pushed her hoof as deeply into her snatch as she could and began to lightly rub her clitoris with her other while letting out little squeals and moans until finally the damn burst.

She shuddered and clenched her eyes shut as waves of pleasure flowed through her before rebounding and concentrating in the spasming walls of her pussy. She arched her back and pushed her hooves desperately against her mound as they were soaked with marecum. Twilight continued to roughly rub herself until the liquid that had built up around her pussy finally caused them to slip off her mound.

When the pleasure finally subsided and she had recovered her breath, Twilight slowly allowed her eyes to open. In front of her face, directly level with her eyes, was a bluish green tentacle. Twilight followed it down and found that the bud of the flower had opened up and several other tentacles had emerged from the flower as well. She looked back up at the tentacle in front of her face and gave it a questioning stare. The tentacle ignored her curiosity though and pointed itself at her mouth, which was still open as Twilight was still breathing hard. Before she could react, the tentacle shot some pink liquid directly into her mouth.

Caught off guard, Twilight was about to spit out the liquid, but before she could, it had mixed with her saliva and become sticky and warm. Unable to rid herself of the goo, Twilight took a moment to calm down and realized that the sticky substance was actually very tasty. She swallowed the goo down and before even thinking about it, opened up her mouth again. The tentacle immediately sprayed more liquid into her mouth and Twilight again happily swallowed it down. When she opened her mouth a third time, the tentacle moved forward and rested itself on Twilight's tongue before spraying more nectar.

Twilight wrapped her lips around the tentacle as gently sucked on it, sighing as she was fed more of the nectar. As this went on, Twilight’s body began to heat up again and before she knew it, her hooves had returned to her pussy and she moaned as she pressed into her walls. She rapidly chased after another orgasm, her pleasure building up faster this time as her lower lips and passage were already pleasantly sensitive from her previous climax. She was soon shuddering as more waves of bliss flowed through her.

She was somewhat disappointed however when the climax ended but that was quickly taken care of as the tentacle poured more nectar into her mouth and with it, Twilight’s arousal burned brightly again. Before she could resume masterbating however, Twilight felt something press against her needy folds. Looking down, she saw another tentacle was brushing up against her soaked nether lips. Normally, she would have hesitated, but with how very horny she was, Twilight pulled her lips apart in invitation.

The tentacle pushed forward easily into her well lubricated pussy and Twilight moaned as it stretched her walls around it. The tentacle continued to push into her until it rested snugly against her cervix, making Twilight sigh in satisfaction at the feeling of fullness. Before she could become too comfortable though, the tentacle pulled out to her entrance, leaving her feeling empty inside, and then pushed back inside much faster than before. Twilight gasped and bucked her hips forward as she was filled again and again, the tentacle falling into a steady rhythm.

Before long, Twilight was pushing into each thrust and gasping every time the tentacle brushed up against her inner barrier. The feeling of the tentacle scraping against her walls, deep inside her, made the pressure of her building climax so much greater and before too long, Twilight was moaning and squirting her essence all over the tentacle and the soil beneath her. The tentacle continued to squirm inside her even as her walls clenched down on it, prolonging her climax making her squirt again and again.

As she came down, the tentacle inside her pussy sprayed nectar into her and as it absorbed into her pussy walls, her arousal returned and grew. Twilight happily sucked on the tentacle in her mouth and patiently luxuriated in her growing horniness. The feeling of liberated sexual desire was thrilling and intoxicating in in of itself but Twilight didn’t complain when the tentacle started moving again. She rolled back onto her back and mewled as the better angle allowed the tentacle pounding into her to speed up and thrust more roughly. Even as her next climax was building, a third tentacle pushed itself up against her puckered anus and forced more of the aphrodisiac nectar into her rectum.

Twilight squirmed as back door became uncomfortably empty and pushed herself against the tentacle rubbing her sphincter. The tentacle took its time though in order to make sure that it didn’t cause Twilight any pain and Twilight let out a long moan as her muscular ring slowly submitted to the new visitor. When the tentacle finally pushed all the way in and sandwiched her sensitive flesh between it and the one in her pussy, she gave a muffled scream and convulsed in bliss as she submitted to another orgasm.

As she began to return from the throes of pleasure, something the the tentacles were doing there very best to delay, Twilight realized that she was not any more satisfied; that her desire for sexual stimulus had not declined at all, even without any more of the nectar. She wondered if the plant was changing her, or at least her libido but it didn’t matter that much to her in the long run. The ever present warmth and horniness, the constant desire that was burning inside her, felt divine. She couldn’t wait to walk around the halls of the castle, tail raised as she displayed her dripping pussy to everypony around her. She wanted the princess to blush when she smelled the scent of arousal coming off her student.

As Twilight fantasized about masterbating even while doing her research in the royal library, the tentacles filled her with more nectar and she shivered as her body became even more needy. The tentacles rapidly pistoned in and out of her alternatively making them scrape against each other deliciously through the thin barrier that separated them and in minutes Twilight was climaxing unfettered again. When she came down this time however, all three of the tentacles retreated from her body.

Twilight groaned in protest but when one of the tentacles poked her flank, she propped herself up and looked at the flower. At its center was a plain looking brown seed.

“Is this for me?”

The tentacle moved up and down in the facsimile of a nod.

Twilight eagerly lifted it out of the flower with her telekinesis. “I’ll take good care of it.”

Twilight was preparing to put the flower back in stasis, but before she could recast the spell, the tentacle poked her flank again. Twilight paused to let the flower do what it wanted to. The tentacle quickly shot deep into her pussy, all the way to her cervix, and shot a big warm ball of nectar deep inside her womb.

She sighed in appreciation as the the liquid added to her constant lust. Twilight finished casting her stasis spell and then returned the flower to its container. Her pussy pulsed distractedly but it didn’t take long for the intelligent young mare to find a solution. She would have to hide the seed anyways. Celestia forbid somepony think she was stealing from the academy. Without hesitation, Twilight bent over and gently inserted the seed into her passage. She clenched down on it several times to make sure it was snug, and to enjoy the pleasant fullness.

Careful to clean up the lab before set back out to return the flower to the librarium, she put away all the instruments and closed up her notebooks and put them away. She also opened a window to let some of the smell fade. As she walked along the halls, she savored the feeling of each step shifting the seed inside her pussy a little bit, causing her to clench down on it with her over sensitive walls a little and happily swished her raised tail back and forth, helping to spread out the scent of her musk coming off her soaked hind quarters and dripping snatch.

She couldn’t wait to get home and plant her very own flower.

Chapter the Second

Twilight skipped back to her tower happily in her snow boots. Though it was sunny outside, the last few patches of snow from the end of winter still littered the ground and feeling the ice crystal crunch under her hooves made Twilight giddy with foalish excitement. She had gone to talk to the princess after finishing up in the laboratory and gotten permission to turn her unused storage room in her tower into a separate bedroom for spike. That way she wouldn’t have to worry about the hatchling stumbling into something he shouldn’t. She wouldn’t need to worry to much though, he had yet to learn about biological reproduction and would not begin going through sexual development for almost three hundred more years.

As she arrived at the tower, she quickly hopped up the winding staircase and stepped inside, relishing the warm interior air as it chased away the lingering winter chill. It also nicely complimented the inner warmth that Twilight was feeling. She had work to do first before she could enjoy herself though and started to remove the seed from her still dripping pussy before deciding against it; No reason to not enjoy herself a little while she worked.

With a flick of telekinesis she set a kettle filled with water on the stove and lit it before going over to the storage room door and flinging it open. The room was actually pretty empty but a fine layer of dust had accumulated on the walls and floor and Twilight quickly conjured up a feather duster and got to work. As she moved around the room she shook her backside in time with the strokes of the duster and giggled as the seed shifted back and forth inside her. As much as she wanted to stop and masturbate Twilight knew she would need to control her urges and focused on enjoying being horny. Of course with the steady drip of arousal from her snatch, she was going to need to mop more often, but it was a small sacrifice.

Twilight finished her chore in record time and after a quick moping she focused her thoughts on the spare bedroom that Celestia had let her borrow the bed out of. With it pictured firmly in her mind, she cast her reverse teleport and the bed sprang up right in front of her. She was particularly pleased at her ability to concentrate on a difficult spell even when she could still feel the warm ball of nectar inside her womb, slowly absorbing into her. With a few more furniture additions and a couple of superhero posters, the room was finished and quite appropriate for a nine year old colt, even if the colt was a dragon instead. Twilight just hoped that Spike would like it. He was basically her little brother after all and she took his care and happiness above all her other responsibilities.

Though now that Twilight thought about it, if Spike was her little brother and the drakeling consider Celestia to be his mom, did that mean Celestia was also her mother by association. Twilight considered that for a minute before deciding maybe it be better that she take steps to disguise her arousal around her mentor.

Satisfied with her handiwork, Twilight exited the room and began to scrounge for an unused plant pot. Though this was her first foray into botany, she had used plants to test some of her spells before and managed to find a generously sized terracotta pot. She would need to replace it eventually as the flower grew, but it would be fine for now. Twilight got out some of her potting soil and once she was satisfied with the results, she gently pulled the seed out of her pussy with her telekinesis while moaning a little as the ridges on it stimulated her inner walls. When she held it up to inspect, she was surprised to see that the seed was already breaking apart, exposing the fat green sprout, which looked suspiciously like one of the tentacles she had enjoyed earlier in the day.

Twilight was delighted that it had already begun to germinate and with hopes that it would continue to grow at a fast rate, she gently placed it in the soil and watered it lightly.

With all of her obligation taken care of, Twilight enjoyed a quick cup of camomile tea before jumping in the shower to clean off. She could just use a spell to clean off but nothing could replace the relaxing feeling of hot water running over her body. As she sat in the tub with the shower spraying down on her, she gently rubbed her foldes and let out pleased sighs. It didn’t feel anywhere as good as the tentacle had, thrusting deep inside her, but her technique was improving and with how sensitive and horny the nectar had made her, it still felt amazing.

She gently flicked her clit while pressing hard into her passage with her other hoof. Much more sure of herself, she was rhythmic and assertive with her motions and as the pressure built, she experimented with how different motions affected her. Stimulating her clitoris cause sharp jolts of pleasure but did little to bring her closer to orgasm. Perhaps if she was on the edge though it would be enough to send her over? Her circular rubbing and partial penetration were the most effective way to close in on her climax but she found that stopping for a little bit and simply pressing her hoof up against her marehood and stroking it up and down was a tantalizingly fun addition to her ministrations.

Out of curiousity, Twilight moved her second hoof down to her anus and as she continued to rub and massage her pussy, she gently pressed against the muscular ring. The sensation was very different from the pleasure of her sensitive inner walls and labia but much to her satisfaction, added an exotic flavor to her masterbation. In fact, she enjoyed it so much that she continued to tease the sphincter, even gently stretching it a little over the tip of her hoof even as she approached her peak.

At the last moment, Twilight stopped rubbing her walls and instead pressed down hard on her clit. She moaned loudly and unabashedly as her pussy clenched down in an attempt to milk a non-existent invader. She rode her orgasm hard as she pushed herself to continue her masterbation even as her comvulsion faded to after glow. Feeling still very horny but satisfied enough for now, Twilight softly rubbed her mound until the water had finished washing away all her marecum.

With her hygene taken care of Twilight set about fixing dinner and by the time Spike arrived, There were two places set at the table for them. Dinner never took long in the tower. Twilight was always in a rush to get back to her studying and Spike wanted to dig into the next comic book he could get his claws in. Tonight he was especially excited to sleep in his new room. Particularly because it would mean no Twilight to tell him to go to bed. Of course, Twilight would start checking in on him, but not tonight; she had already done enough work for today and couldn’t wait to soak her sheets in her own marecum.

Once Twilight was sure that Spike wouldn’t disturb her, she put up a sound proofing spell around her room. She hopped up onto her silk sheets and spread her legs apart. The nectar in her womb had almost completely absorbed but there was still just enough to feel it warming her up from inside and Twilight sighed as she prepared for the pleasure she was about to bring to herself.

She grabbed her silk top sheet in one hoof and gently rubbed the smooth fabric against her marehood, enjoying the new sensation before pushing it between her nether lips. The silk glided effortlessly across her labia making her moan softly as she reached around and teased her anus with her other hoof.

Twilight pressed her cloth wrapped hoof into her passage way but as she pushed and rubbed harder and faster, she became frustrated by the lack of penetration. In a flash of inspiration, she used her telekinesis to wad the sheet up into a cylinder and thrust it inside her pussy. She screamed as she forced the improvised phallus all to way up to her cervix before starting to roughly piston it in and out. With her hoof now free, Twilight began to rub and pinch her clit and in no time at all she was spraying her cum out onto her bed.

She brought the now soaked sheet up to her mouth and took a big whiff of the musk coming off of it. Twilight purred as the pheromones burned inside her nose and softly lapped at the liquid dripping from the sheets. It was hard to define why but to the horny mare it tasted delicious and she greedily sucked more of the soaked fabric into her mouth. As she enjoyed her tasty treat, Twilight returned to masterbating, using her telekinisis to aid her hooves and when she climaxed again, she caught her cum in a levitation field and letting the saliva soaked silk fall out of her mouth, she eagerly poured the cum all over her tongue.

When she finished, Twilight giddily returned her hooves to her still very aroused pussy. Tonight was going to be fun…No, every night was going to be fun.


When Twilight awoke in the morning, she yawned and stretched her hooves out, smiling as her matted fur pulled away from the sticky sheets she had slept in. She was even more happy to find that as her body started to wake up, her pussy was already wet with fresh arousal and she sighed as her mind became half fogged and horny. She hopped off her bed and trotted over excitedly to her seedling only to find it in a sorry state. It had grown a little and the rest of the seed’s hell had fallen off, but the bright blue green color had faded to a more grey color and Twilight could tell it was in distress.

Thinking quickly, Twilight could only imagine that the new plant must need some other source of sustenance and since it had germinated inside her pussy, maybe putting it back would save it. Wasting little time, Twilight gently scooped the seedling out of the pot and pressed it against her folds. As soon as her arousal began to run over it, the young plant started to move a little and color began to return to it. Pleased with her progress, Twilight pushed the seedling into her passage and then used her telekinesis to force it further down.

Twilight danced around the room happily and clenched down on the seedling, sending little pulses of pleasure through her body. She didn’t have time to play though because she had to go to the market and after a quick cleaning spell, Twilight trotted out into the late morning sun. It was considerably warmer today and so Twilight set out to do some shopping.

Every now and then, the plant would squirm inside her pussy and Twilight would let out a small squeak or moan. As she walked through the marketplace, unabashedly presenting her wet pussy, Twilight soaked in the attention. Sex was not really a big deal culturally, especially when a significant portion of the population became uncontrollably aroused every spring and a mare secure in her sexuality had nothing to fear from most of the public. And when you were the strongest unicorn born in the last century, the small number of ponies that were dangerous didn’t matter either.

The whistles and cat calls from other ponies as she went about her shoppin though was deeply satisfying to Twilight and as the day went on and she came close to finishing her activities for the day, she noticed that the plant inside her had grown significantly. It was also getting more active, wriggling and squirming constantly. Twilight shivered as her lust and pleasure began to start building towards climax. Once she was in a somewhat secluded side street, with only a few ponies walking in and out. She turned towards the wall and arched her back, pushing her butt into the air before reaching back with one hoof while she folded the other and rested her chest on it.

As soon as her hoof tip made contact with her pussy lips she was lost in her own world. She could hear the sound of a small crowd gathering around her but it only made her rub more vigorously and moan louder. She was so excited by the feeling of other ponies eyes on her that when her walls started contracting around the plant she couldn’t help but spray her release all over the ground and in the faces of a few onlookers. When she finally turned around and what she had done registered in her mind, Twilight gently picked up her groceries in her magic and giving her soaked hoof a long sensual lick before winking at the gathered ponies and teleporting back to her tower.


When Twilight reappeared in her dining room, Princess Celestia was sitting at the table, calmly sipping at a cup of tea.

“Princess?”

“Hello Twilight.” Celestia gestured to the seat opposite her, “Please sit down.”

Twilight nervously pulled the chair out and sat down. Though she had fantasized about exposing her mentor to her new sexual excitability, Twilight found the reality to be much less pleasant.

“You wouldn’t believe the rumors I’ve been hearing all afternoon.” Celestia said with a glint of mischief in her eyes as she poured a cup of tea for her student. “Two sugars?”

“Please.”

Twilight accepted the cup of warm liquid and sipped at it, waiting for Celestia to continue.

“No less than half a dozen nobles fancy that they saw a young mare walking about the market place with her hind quarters wholly exposed.”

“How about that,” Twilight chuckled nervously.

“What's more is, how did High Hat put it? ‘She was less decent than a common mare come spring time.’”

Twilight swallowed, but stayed silent.

“And you know what the silliest part of this fantasy was?”

“No.”

Celestia looked Twilight in the eye and exclaimed with a playful grin, “They swore it was you.”

Twilight, slowly set her tea cup down on the table and closed her eyes. She took deep breaths to try and quell the uncomfortable feeling in her gut. When she opened her eyes again, Celestia had risen and was walking around the table to her.

“Did you know my faithful student that I had checked up on you yesterday.”

Twilight shook her head.

“I was worried that despite knowing how capable you were, that somehow you would be hurt while experimenting alone.”

Twilight shakily took a sip of her tea.

“Did… Did you?”

“Yes Twilight I did see you become… Occupied with your choice of flower, though I promise I didn’t peek for long. I respect your privacy and was simply grateful to see that you were safe and well.” Celestia gave Twilight another knowing smirk, “However, evidence has come to light that perhaps you may not have cared about having an audience.”

“I’m sorry princess, I shouldn’t have let it do that. I shouldn’t have gone out in public like that, I shouldn’t have masturbated in front of other ponies.”

Celestia blushed deeply at Twilight’s last confession.

“Oh my, did you really?” she responded with a rueful laugh.

Twilight only nodded in shame.

“Twilight, you are practically an adult and intellectually, you are more adult than most of the nobles that I see each day.”

Celestia paused and placed her wing over her dejected student.

“You are more than capable of making decision that relate to your body and your… sexual conduct.”

Twilight’s ears rose up in attention.

“I only came to speak with you because I wanted to remind you that while in public, what you do is seen by many whether they want to see it or not. Perhaps you should give greater thought before acting so… relaxed while there are others around.”

Twilight sighed. “I know. Just…”

“What’s wrong?”

“Ever after I… I had sex with the flower. I’ve felt horny all the time. I think it might even be permanent. And well, the idea of all those ponies watch made me feel so good.”

Celestia giggled at her flustered students response.

“Oh Twilight, I would never allow the Academy to keep anything so drastic life changing in general. The effects of the flower aphrodisiac are just long lasting. Depending on the level of exposure, you could be this way for another week or so.”

Twilight made a noncommittal gesture.

“I was really hoping that you might actually find out more about the flower though. Years ago a mare by the name of Sun Gazer found that the liquid could be used to synthesize a powerful healing draught,” Celestia sighed sadly, “Unfortunately, all attempt to get the plant to reproduce failed. It seems that the seed has a very distinct requirement for survival, but the academy was never able to find out what it was.”

Twilight’s face immediately lit up and she smiled broadly.

“Do you have something to add my dear?”

“I figured it out!” Twilight jumped out of her chair.

“You did?”

“Yes!”

Twilight started skipping around the dining area in excitement, which also seemed to wake up the plant inside her and she blushed a little as she unconsciously began to clench against the wriggling seedling.

“It needs the naturally lubricant and cum that a mare produces while aroused and orgasming.”

Celestia covered her mouth and giggled while blushing lightly. “Oh my goodness, that is very unique.”

“It is!” Twilight agreed excitedly.

“Does this mean that a mare must… Keep it with her?”

“From what I can tell, a mare must keep it within her vagina during the developmental portion of its live cycle.”

“I see, and that means that you…” Celestia gestured to twilight as she trailed off.

“Have one inside my passage right now, yes.” Twilight finished hopping around and stood
proudly. “The growing plant even exhibits motion similar to that of the adult flower.”

“Well… This has been enlightening.” Celestia walked over to the door. “:I expect that regardless of lifestyle changes, you will be ready for our lesson tomorrow on time. I would also, on behalf of the Royal Academy, like to thank you for your discovery and I hope you will approach this in a proper scientific manner. I would also like you to visit Rain Whistle in the alchemy depart if you find a suitable method of collect the discharge of the flower.”

“Of course Princess,” Twilight gave a mock salute, unaware that her face was stained a rosy red and she was now giving off a distinct smell of full arousal.

“Very good then my faithful student, I will now leave you to...stuff.”

And with that, Princess Celestia walked out the door and shut it behind her.

“Oh my gosh, this is the best day ever!” Twilight shouted to herself, “I can’t wait to masterbate.”

Chapter the Third

View Online

Twilight had managed to sleep pretty soundly despite having the young plant wriggling inside of her for most of the night. She was happy to wake up already close to orgasm though and as she started to clench down on the tentacle seedling she felt it push itself deeper into her. It had grown by a lot, which was easy to tell as her fluttering pussy wall stretched over it. What was more important to her though, was the familiar tingling of the plants nectar that began to coat her insides.

Twilight moaned huskily as the sweet scent of the flowers aphrodisiac began to mix with smell of her own arousal. She gently got off her bed, careful not to dislodges the plant and went about her morning routine. She didn’t have too much time to spare since she needed to meet with the Princess before court opened for their personal lessons. So after breakfast and a magical plug to keep her arousal and the plants nectar from leaking out, she made her way to the palace.

Her lessons passed without a hitch and after a short lunch, she was on her way back to the Academy to meet with the alchemist that Celestia had wanted her to see. The Academy wasn’t actually on the palace grounds and on her way there Twilight got more than a few awkward glance from nobles that had heard about her antics yesterday. Twilight did her best not to lift her tail more than she already was nor stick her tongue out at the prudish unicorns. As she reached the Royal Academy the atmosphere changed drastically.

Many of the other scientists stopped to congratulate Twilight as well as ask her about what she planned to work on. She humbly accepted their praises with a much more reserved attitude. It was one thing for her to be so uncaring in public but the Academy was a place of science and Twilight felt more than a little intimidated by being surrounded with other ponies with far more experience than her. As she made her way through the halls she did her best, and mostly unsuccessfully, tried to be as unnoticed as possible. She finally reached the alchemy labs deep inside the basement levels of the building with her nerve still intacted. SHe carefully counted the doors as she walked down the dim hallway. None of the labs down there were marked as the entire alchemy division was made up of by one pony and when Twilight opened the fourth door on the left she was immediately stopped by a thick north eastern accent.

“Hold it right there won’t you?”

Twilight squinted into the darkness before making out a dim glow on the other side of the room.

“Be right with ya, just got to secure a few things.”

“No problem,” Twilight shuffled her feet as she waited.

One of things about being horny all the time was that if she wasn’t moving, it was hard to not let herself drift into the fogginess of lust. And the growing plant had been slowly secreting its aphrodisiac all day now. Which was good because Twilight would be able to get the samples she needed, Unfortunately, it meant she really just wanted a nice big tentacle shoved up her vagina at the moment, well technically another one.

“Sorry bout the wait.”

Twilight was shaken out of her reverie by the sound of wings beating in front of her.

“Ah, if it isn’t the prestigious Twilight Sparkle. Name’s Rain Whistle what can I do for you love?”

Twilight took a moment to study the pegasus mare in front of her. She had a coat the color of summer rain clouds and summer sky blue mane to go with it. Her hazel eyes were bright and shone like the first rays of sunlight after a passing storm. Judging by her youthful demeanor and agility, she couldn’t have been more than twenty or so.

“Wait, you're not supposed to be flying inside the laboratories.”

Rain Whistle dropped to the ground in front of Twilight and gave a mirthful laugh.

“Perfect to a T aren’tcha? Special circumstance in here. Wouldn’t want to step in a rune circle now would we?”

Twilight conceded the point with a shrug.

“I guess that makes sense, but why are you working in the dark?”

“Chemicals are light sensitive, easier to work on their level than make them work on mine. Why don’t we step next door. Its pretty empty and not a hoof step away from exploding?”

Twilight chuckled nervously as she stepped out of the doorway.

“Your joking of course. Right?”

“Love, why do you think we are three stories underground?”

Without a word, Twilight walked over to the next lab door and hastily made her way inside.

“Ah, much better now. I was beginning to forget what light looked like.” Rain Whistle motioned for Twilight to sit down at one of the tables, “Now The Princess said you had something important to share with me?”

“Yes, of course.” Twilight teleported a thick manila folder onto the table between them as she sat down. “I brought all of the materials pertaining to the matter with me. Also, there is a short summary that I wrote on top.”

Rain Whistle deftly snatched the folder up with a wing and pulled out the report Twilight had made. She started whistling a happy tune while she read. At a few parts the tune was interrupted by a couplet of high notes instead.

“Well doesn’t that just take the cake.” Rain Whistle set the the folder back on the table. “This isn’t some prank by the princess is it?”

Twilight shook her head.

“Well, guess we should get to work then, unless you have plans?”

“Oh no, I can’t wait to get started.”

Rain Whistle nodded before taking to the air as she made her way over to the cupboard around the room.

“I assume you brought the research subject with you.”

“Yes, I have it safely in my… Well my vagina.” Twilight trailed off.

“No need to be flustered, we’re all mares here. Still, if you prefer some privacy, there is a bathroom down the hall.”

“No, It’s okay.”

Twilight picked up a large pot that had been pulled from the shelf and levitated it over to herself before sitting on it much like she would a toilet. When she released the magical plug though, the strong smell of the flowers nectar as well as Twilight’s own musk began to fill the room.

“Well, that's some strong stuff isn’t it,” Rain Whistle commented as she approached Twilight.

Twilight concentrated on the object inside her pussy and with her telekinesis slowly pulled the stubby tentacle shaped plant out of her inner passage. She couldn’t help but moan as it scraped against her walls before coming free. She gently set the plant in the pot and stood back up.

“Well then,” Rain Whistle stared at the pot for a moment, blushing slightly. “I imaging that felt pretty good.”

“If I move around enough, the seedling will start wiggling too and it feels amazing.”

“Right.”

Both mares stared awkwardly at the liquid filled pot, shuffling their hooves.

“I guess we should start where the last person left off then?” Twilight suggested quietly.

“Yes. We should do that.”

Rain Whistle turned around and pulled a test tube out of one of the racks and dipped into the mixed fluids with tongs.

“Of course, we will need to separate the plants fluids from your own discharge.”

“How do we do that?”

“Well, we will need a sample of your fluids that are uncontaminated by the nectar and then a sorting glyph should do the rest.”

Twilight shuffled awkwardly, finding the idea of masterbating in front of a fellow scientist oddly much more difficult than it had been in the market the day before.

“Bathroom's down the hall on the left.”

“Ah.” Twilight started walking back to the door.

“Don’t forget to clean yourself out first or you will contaminate the sample.”

Twilight nodded and stepped out into the hall.

It didn’t take long for Twilight to complete her task and in a few minutes she returned with a sphere of her arousal and cum suspended in her telekinesis.

“Perfect, now just put it into this beaker on the glyph.”

Twilight followed instruction and very soon the two mares had a sizable quantity of pure nectar to work with. The excess fluids were returned to the pot in order to keep the seedling well fed. Rain Whistle would alternate between whistling and questioning Twilight about her life while she in turn spent most of the time taking thorough notes of their progress.

“I’m not sure I understand why this is supposed to be a basis for healing application.” Rain Whistle state casually as she pulled the final beaker out of the power rune she had been working over.

“I think that the nectar has a natural healing component in it already. In my experience, after rough and even extensive sexual stimulation, I haven’t had any problems with soreness or skin irritation. I can imagine that it is because the nectar is speeding up and revitalizing those areas.” Twilight rubbed her chin in thought. “I suppose it must also affect metabolism since I also haven’t had problems with running out of natural fluids despite many orgasms. Though I have been more hungry and thirsty which make sense.”

“I guess that clears some things up.” Rain Whistle walked over to the ‘research table’ and set down the final product in front of Twilight. “There we go, that's the original recipe that you found,. Now how about we call it a day and get something to eat?”

Twilight looked over at the clock and blinked in surprise. They had been working for almost three hour straight at this point.

“Yeah, that might a good idea,” Twilight chuckled.

The two mares walked over to the pot that the plant had been sitting in and Rain Whistle let out a surprised gasp.

“Well, that might be a problem…”

Twilight stepped up next to the pegasus and looked inside herself. The plant had lengthened considerably and had formed a bulb on at one end.

“Well, I mean the bulb isn’t that big.” Twilight said with a significant blush.

“Yeah, but what the hay are you going to do with that much of it’s tentacle?” Raind Whistle countered. “You sure you shouldn’t just plant this thing and be done with it?”

“I still don’t think it would survive yet, I would guess that the petals of the full grown flower are the only photosynthesizing parts of the plant and those won’t develop until it is almost fully grown.”

As the two mares discussed the problem, the tentacle coiled itself up like a snake and lifted out of the pot. Before either mare noticed It sprayed them with a huge amount of the aromatic mist that the adult flower had produced. Both mares stumbled back cough as the tried to clear their lungs. After Twilight’s initial survival instincts had worn off however, she stepped back into the hazy cloud that still hung in the air and took a deep breath of the mist.

Without the plant in her for most of the afternoon, Twilight’s arousal had been fading but when she was exposed to the smell again, it reminded her of how much hornier she could be right now, how much hornier she wanted to be right now.

“I don’t think you should be doing that.” Rain Whistle said as she backed away from the pink cloud.

“Don’t worry,” Twilight sighed. “It won’t hurt you. In fact, it is so much better to just give in to it.”

Twilight scooped Rain Whistle up in her telekinesis and pulled the mare into the cloud. The pegasus was too surprised to hold her breath and was immediately assaulted by the sweet scent. Twilight was content to hold her inside the cloud as she went to check on the plant. As she approached the tentacle rose up again and a single bead of nectar dripped from its tip. Twilight couldn’t wait to taste the amazing liquid again and quickly brought the tentacle into her mouth before starting to suck and massage it with her tongue.

The tentacle poured a generous amount of the nectar into Twilight mouth and she happily drank it down before sucking for more. The tentacle obliged her but immediately withdrew from her mouth after transferring its gift. Twilight gave it a curious look, cheeks still bulged out with liquid. The tentacle pointed itself at the other mare and Twilight nodded in agreement.

“Twilight Sparkle you damn well better let me go,” Rain Whistle threatened even as a small blush began to appear on her cheeks.

Twilight simply ignored her though and stepped up to face the other mare. She wrapped a for hoof around Rain Whistles head and pressed the mares lips against her own. Rain Whistle held her lips closed tight while she struggled but Twilight covered her nose with her magic and when the pegasus was forced to take a breath, Twilight pushed the nectar she had been saving in her mouth into the other mares. Struggling with her need to breath, Rain Whistle was forced to swallow the aphrodisiac before Twilight pulled their mouths apart.

“Why would you do that?” Rain Whistle implored between panting breaths.

“You’ll see.”

Twilight went back over to the tentacle and it quickly filled her mouth again. This time when Twilight returned, Rain Whistle had accepted the consequence of fighting with the unicorn and begrudgingly accepted Twilight's kiss. Seeing her resistance fade, Twilight was slower and more gently as she passed the nectar on, using the time to press her tongue into the other mare’s mouth and explore as the pegasus swallowed down the forced meal. When Twilight pulled away this time, Rain Whistle gently closed her lips around the unicorns tongue and gently sucked on it until it retreated from her mouth.

“See, isn’t that so much nicer?”

Rain Whistle didn’t respond and just hung her head as her blush and shame grew.

Twilight walked around her captive and giggled as she reached the pegasus’s hind quarters. Rain Whistle didn’t realize it but there she was definitely pushing her butt out and her tail was gently twitching to the side. Twilight enjoyed seeing the first few drops of arousal collect at the entrance to the pegasus’s pussy and with careful attention collected just a little on the tip of her hoof. She licked off and moaned sensually at the flavor. It tasted just like the air on a rainy day but sweeter and a little musky.

Twilight was about to give Rain Whistle’s nether lips a lick but halted what she was doing.

“Oh my goddess.”

Twilight released her telekinesis and the pegasus mare slumped to the floor.

“I’m so sorry. What have I done.”

Twilight ran panicked to face Rain Whistle and gently propped the mare up with her hooves.

“Are you okay Rain Whistle?” Twilight lifted her face so she could see eye to eye. “Please say something, are you okay?”

Rain Whistle however just stared blankly at Twilight.

“Oh, how will you ever forgive me? I wouldn’t forgive me. The Princess is -”

Twilight was interrupted by the pegasus as she pressed her soft lips against Twilights. She tried to pull away, but Rain Whistle wrapped her hooves around Twilight’s and pulled them together. The feeling of the other mare’s kiss, the soft fur of her muzzle brushing against her own, reminded Twilight of her own longing. Before long, Twilight was mewling pleasantly as they eagerly mashed their lips together.

The arousal flared up in Twilight and sent pulsing heat through her body, making her more impatient and she stuck her tongue out and began licking at Rain Whistle’s lips. The pegasus giggled before enclosing the saliva slick muscle with her mouth and sucking and licking at it. Twilight moaned as their tongues danced together and Rain Whistle eagerly reciprocated the sound of pleasure.

When they eventually parted to catch their breath, Rain Whistle took Twilight's head in her hooves and looked her in the eyes. All of the passion and desire drained from the pegasus’s face and her expression became hard.

“Twilight Sparkle,” she said seriously, “Do you want this?”

Twilight nodded meekly under the suddenly intimidating pegasus’s glare, afraid to break eyes contact.

Rain Whistle paused for a moment and then pushed herself up against the smaller unicorn, wrapping her hooves around Twilight’s barrel. She then flapped her wings and took to the air for just a moment before landing softly on top of Twilight.

Twilight, now on her back, wrapped her own legs around the pegasus and pulled her down on top of her. As they pressed their bodies together, Twilight's desire skyrocketed. The heat of Rain Whistle’s body, along with her smell and the taste of her saliva pushed everything not related to their embrace out of her mind. She relaxed and allowed her partners hooves to roam her body while she in turn explored the pegasus’s soft coat and whenever she touched a spot that was particularly sensitive, Rain Whistle would let out a little moan through their heated making out. Twilight made note of these spots and made it a habit to return to them. Rain Whistle seemed to be particularly sensitive around the base of her wings, not surprising.

Rain Whistle pulled away from Twilight and the two of them laid panting as they continued to hold each other. Twilight’s pussy was burning with need and she could feel the pegasus’s arousal dripping onto her.

“Ready for the fun part?” Rain Whistle asked with a sultry grin.

She was definitely ready, but Twilight took the opportunity to re-assert control and after a quick flash of light, Rain Whistle was now pinned under her. Before the pegasus could protest though, Twilight turned around and laid down with her pussy right above Rain Whistles face. Twilight hooked her legs around the other mars backside and leaned in, giving the musky arousal leaking out of Rain Whistles snatch a big sniff. She sighed as the pheromones burned pleasantly in her sinuses just like her own had before slowly dragging her tongue along the outside of her folds.

Twilight moaned as the taste hit her tongue and immediately went in for another lick. Rain Whistle hadn’t been completely inactive though; Twilight’s own arousal poured out like a weak facet and the pegasus eagerly caught the mare juice in her mouth as she massaged Twilight’s butt and pulled the unicorn towards her. She gasped as she felt Twilight’s tongue run along her pussy lips but spurred herself on and wrapped her lips around Twilight’s mound. Both mare moaned and grunted shamelessly as they lapped at each others fold.

Rain Whistle was the first to press ahead and as she pushed into Twilight’ passage, scooping away more of the liquid still stained with the taste of the plants nectar, causing the unicorn to moan into her snatch. The pegasus gasped as her wall vibrated in time with Twilight’s voice and then moaned herself as the unicorn pressed her tongue deep into Rain Whistles pussy. Twilight watched as Rain Whistle’s juices along with her own saliva trailed down between the mare’s ass cheeks and decided to take a chance at getting ahead of the other mare. With a little bit of magic she gently began to rub the lubricating liquid into the mare’s tight sphincter.

With her masterful ministration, Twilight soon had Rain Whistle on the ropes and could feel her walls starting to squeeze down on her tongue. Twilight pulled her tongue free and latched on to the pegasus’s clit, sucking it gently and biting softly on the tender nub. Rain Whistle screamed into Twilight as she started to climax and her cum began to pour out, Twilight returned her tongue to the mares snatch and happily licked up as much of it as she could. She was content to let the mare ride out her orgasm even if it meant that she had stopped pleasuring Twilight but the unicorn made up for it as much as possible by grinding her nether lips against Rain Whistles muzzle.

When she finally stopped Cumming, Rain Whistle went limp and Twilight used her magic to push herself to climax as well. She sighed happily as she shuddered and sprayed her own cum onto the mare’s face beneath her. She then collapsed on top of the panting mare, letting her face fall between Rain Whistle’s legs, and simply enjoyed the pungent smell of her partner's left over sex juices.

“That was amazing.” Rain Whistle said as she finally caught her breath.

“Oh don’t worry,” Twilight said in between her own heavy breathing. “It gets better.”

“It does?”

Twilight crawled off of the pegasus and Turned around to snuggle up against her partner.

“Of course. The nectar that the plant produces helps revitalize the body and prepare it for continued sexual activities.”

Rain Whistle wrapped her legs around Twilight and pulled her face to face.

“I love it when a mare talks science to me.”

Twilight giggled and started licking away her own juices from Rain Whistles face. The pegasus enjoyed the tongue bath for a second and then decided to return the favor, though Twilight’s face was much less messy. Once Twilight was satisfied, she captured the other mares lips in another kiss and as their tongues collided and pressed against each other, both mares quietly moaned at the heady taste of their combined saliva and mare cum.

They continued to make out for several minutes, moaning and gasping as their hooves traveled around each other’s bodies, massaging and stimulating them until Twilight unexpectedly gasped and pulled away.

“What’s wrong?” Rain Whistle asked as Twilight rolled away from her.

Twilight didn’t answer and instead the pegasus followed her gaze down to in between the unicorns hindlegs. The plant had escaped from its container and was now sitting on the floor, trying to press the large bulb into Twilight’s pussy.

As Rain Whistle watched, Twilight tried to redirect the tentacled end into her but it rose up instead and plunged into Twilight’s mouth and immediately started pouring its nectar into her. Twilight knew that is she kept swallowing it she would almost definitely give into the plant but it was just too tasty not to and she craved feeling hopelessly horn from the powerful aphrodisiac it contained. She half heartedly struggled with it for a moment before she gave up and began humping against the body of the plant.

“Um, I don’t think that’s a good idea Twilight,” Rain Whistle said hesitantly.

The tentacle came out of Twilights mouth and wrapped around her body for support as it pressed itself against her pussy.

“I don’t care,” Twilight panted with need. “I have to have it inside me.”

Realizing that there was no fighting with the powerful unicorn and remembering the consequences of doing so earlier, Rain Whistle scooted up behind her desperate partner and wrapped her in her hooves while kissing and licking along her neck and ears. It worked and as Twilight relaxed, the bulb began to make progress, stretching Twilight’s nether lips over its fat body. Twilight moaned as it began to slip in. Rain Whistle moved her hooves lower, using them to help pull open Twilight’s pussy lips and despite her trepidations, seeing her partner stretching around the large object was making her more than a little horny again as well.

The tentacle saw the pegasus helping and as a reward it stretched itself up to Rain Whistles mouth. She gently took the tip into her mouth as it began to secrete more nectar. While Rain Whistle helped stretch her open, Twilight used her own hooves to press the bulb into herself and once it made it over half way, the tension forced it to slide all the way in with a quick slurping sound.

Twilight sighed as the heavy object settled in her passage and when the tentacle removed itself from the now rosy cheeked pegasus, Rain Whistle gave the unicorn a loving nuzzle and a quick peck on the cheek.

“Happy now my slutty little mare?”

Twilight nodded and relaxed against the larger pegasus, enjoying the closeness. It didn't last long however as the tentacle wrapped itself again around her legs and began pushing deeper. Twilight squeaked in both pleasure and pain as it started to press against her cervix, causing Rain Whistle to give her a concerned look.

“Is everything okay?”

“I think it wants to get deeper.” Twilight said as she cringed.

Rain Whistle looked down at the tentacle and realised that she could see the deformation that the bulb had made in Twilight’s abdomen. It did look like it was trying to go deeper. The pegasus was contemplating pulling the whole plant out of Twilight, but a larger part of her wanted to see what would happen when the bulb reached its goal.

“Shhh, just relax,” Rain Whistle whispered to Twilight.

She grabbed the tip of the tentacle, which was hanging off to the side and pressed it against Twilight’s already stuffed folds. Understanding what the pegasus wanted, the tentacles sprayed more of its nectar into Twilight’s pussy. As her inner passage became more sensitive to the pleasure of the plant filling her up, twilight’s gasps of pain started turning into moans of pleasure and she rocked herself against the tentacle every time it pressed against her.

The bulb was somewhat tapered at one end and when it finally got its alignment right, Twilight’s cervix began to stretch a little around the tip, but it was still slow going.

“Twilight hun, I think your going to need to use your magic,” Rain Whistle suggested.

Twilight nodded in agreement and fought for enough clarity to cast her telekinesis. Once the familiar magical aura appeared around her horn, the unicorn was able to begin applying direct pressure to the bulb inside her. Ghe let out a long continuous moan as the plant slid its way in inch by inch before finally popping in and settling snuggly inside her womb.

With her ordeal over, Twilight's walls clamped down on her new tenant and she moaned again and again as more cum spilled out of her. Rain Whistle gently placed the orgasming mare on her back and then began licking around the tentacle at her spasming folds. Along with Twilight’s musky flavor, Rain Whistle tasted more of the plants nectar coming out of her and indeed the bulb itself was starting to secrete fluids as well. Though this new liquid was also a very potent aphrodisiac, it also different chemicals that would let Twilight’s body and womb stretch without causing permanent harm or damage.

When she finally stopped cumming, the tentacle in Twilight's pussy began to retreat into her and she moaned as her abdomen began to stretch more and more as the plant filled her. The feeling of fullness, along with it rubbing across her pussy walls and even through her stretch cervix all felt amazing. By the time the tentacle stopped and only its tip rested just outside her womb, Twilight was unbelievably aroused. It left her looking like she was a few months pregnant and Rain Whistle couldn’t deny that it was extremely sexy.

“Please fuck me.” Twilight gasped as she arched her back, desperately presenting her leaking snatch.

The pegasus didn’t need to be asked twice and she stepped over Twilight before interlocking their legs and pressing her own dripping marehood against her partners. Both of them moaned as they started bucking and rubbing against each other. Twilight reached up and pulled Rain Whistle down on top of her before hungrily invading the mare's mouth again. Both mares moaned back and forth as they rubbed and writhed against each other. With how full she felt, it wasn’t long before Twilight climaxed and sprayed her cum into both of their crotches, but even as she pulled away from the kiss to give the unicorn room to breath, Rain Whistle continued to grind sloppily against Twilight’s slippery cunt. Soon, Rain Whistle joined Twilight and added her own deposit to the juices that now covered most of their lower bodies.

Rain Whistle was about to get off of Twilight but the unicorn held her fast as she felt the plant move inside her again. She moaned as the tentacle pushed to her entrance and then began to snake into Rain Whistles folds. At the unexpected intrusion, the pegasus clenched her inner walls tight but in response, the tentacle shot more nectar up into her pussy.

It only took a few moment before Rain Whistles inner passage was burning with the need to be filled and she began to push against Twilight's folds as she allowed the tentacle to push into her. Rain Whistle quickly saw why Twilight enjoyed being filled so much as the tentacle wiggled against her velvety walls. She eagerly pressed herself against the welcome invader and Twilight began to push into her as well. Without a word, Rain Whistle returned to Twilight’s lips as they continued to mash their pussies’ together.

The personal contact with the other mare on top of the pleasure from the tentacle stretching her walls quickly had Rain Whistle climaxing again. As her walls pressed against the plant it started to spue out more warm nectar and the pegasus’s orgasm started all over again. Even as she spilled her cum all over Twilight, she couldn’t help but desperately thrust against tentacle, trying to get more pleasure out of it.

It wasn’t too long before Twilight started climaxing again as well and after being in contact with the plants aphrodisiac for so long, it did nothing to release the need that she felt. In fact, even as wave after wave of pleasure flowed through her, Twilight could feel her arousal and desire get bigger and moaned deliriously as Rain Whistle began bucking against her again.

The two mares continued their frenzied activities even as a puddle of their combined juices began to form on the floor and only finally stopped when they became physically incapable of continuing.

Rain Whistle collapsed to the floor and held Twilight tightly as the tentacle kept them connected. Both mares panted and pressed against each other, desperate for the intimate closeness even if they couldn’t keep up with their sexual needs. As a parting gift, the tentacle pressed up against Rain Whistles cervix and poured a generous amount of nectar inside her before slipping out. The warm fullness made the pegasus whimper desperately and nuzzle against Twilight.

Twilight, being more accustomed to the constant arousal, recovered a lot sooner and gently stroked Rain Whistle’s mane while she placed kisses all over the pegasus’s head and ears. This continued until Rain Whistle had recovered enough that she wasn’t completely paralyzed by her lust and after just enjoying the embrace for a minute, started to get up off the floor.

Twilight rose with her and the two mares leaned against each other for support as well as for affection.

“That was,” Rain Whistle paused for a second, “Impossible?”

“If you mean impossibly great then yes, it was.” Twilight said before giving the other mare a quick kiss on the cheek.

Rain Whistle nodded, still trying to digest what had just happened.

“So… The plant is in your womb now?”

Twilight giggled. “You helped it get there silly.”

“Yeah, I guess. I just… are you okay? Does it hurt?”

“Not really,” Twilight rubbed her chin. “It feels a little stretched, but even that feels pretty good. But what are we now?” she asked hesitantly.

“Research Partners hopefully.”

“Well, obviously, but I mean the whole, having gratuitous amounts of sex thing? And...” Twilight dragged her hoof back and forth across the floor, “Maybe more?”

“Well,” Rain Whistle said after a moment of thought, “They say relationships built purely on physical attraction are not very successful.”

Twilight flinched at the pegasus’s reaction, which in turn made Rain Whistle internally berate herself.

“But, I had a wonderful time working with you before all this and I would be willing to try dating.”

“Yes!” Twilight shouted. “I mean, I think that would be a good idea… For science”

“For science.” Rain Whistle giggled at the unicorn’s reaction.

“And even if it doesn’t work out,” The pegasus continued, “There is plenty of evidence that friendships based off of casual sex can be rewarding in in of themselves even if the two or more parties aren’t romantically compatible.”

Instead of answering, Twilight nodded happily and finally separated from Rain Whistle before starting to clean up.

“Well, I don’t know about you, but I am starving. I propose we start this dating experiment immediately after cleaning up the mess we’ve made.”

Rain Whistle nodded in agreement and began to mop up the spent sexual fluids at her feet.

Chapter the Fourth

View Online

Twilight and Rain Whistle walked side by side down the mostly empty streets of Canterlot's market district. Snow was falling lightly and a gentle breeze was kicking up small flurries of white. The cold didn’t bother Rain Whistle but Twilight shivered; she had decided to teleport her saddle along with all of the materials she was taking with her home. Rain Whistle extended her wing and gently brushed the light dusting of snow off of Twilight's back before laying the warm feathery limb on the unicorn's back and drawing her up close.

“Thanks.” Twilight snuggled up against her date.

Rain Whistle just smiled and kept whistling a holiday tune as they each scanned the building for a place to eat. Though secretly each was enjoying the calm walk and was hesitant to be the first to end it. As the wind began to pick up however, their decision was made for them and they quickly retreated into Les Aliments et les Boissons.

“Goddess look at the menu.” Rain Whistle said.

“I know, I come here with the princess for dinner sometimes,” Twilight replied excitedly, “They have wonderful Prench onion soup.”

Rain Whistle took hold of Twilight's head and directed her gaze to the prices.

“Oh, that menu…”

“I couldn’t afford a salad and a drink here.” Rain whistle said dejectedly.

The pair was interrupted by a polite cough from behind them.

“Let me take care of that for you.”

The two mares turned and found Princess Celestia standing behind them.

“What are you doing here?” Twilight asked with both surprise and joy.

“I had a dinner engagement with some members of the council and was on my way out.” Celestia gestured for the maitre de to come over. “See that these two are taken care of, send their bill to the castle please.”

“With pleasure your highness.”

Celestia turned back to Twilight and Rain Whistle and studied them appraisingly.

“You would do well to give them a private booth as well.,” Celestia said with a knowing smirk.

“Of course.” The gentlecolt turned to the two blushing mares, “If you would please follow me ladies.”

As Twilight and Rain Whistle started to walk away Princess Celestia whispered in her student’s ear, “I let you decide if you want to write me a report on this,” turning Twilight’s blush into deep crimson rash.

Rain Whistle was stunned as she walked through the dining room, there was more money in any given suit coat then she made in a month.

“Twilight, are you sure this is a good idea?”

“It will be fine, we are going to have a private table anyways,” Twilight replied, happy to have the oppressive silence broken.

The two mares were promptly seated and as Rain Whistle began to acquaint herself with the menu, Twilight cautiously slid around the table until she was directly next to the pegasus.

“Is there something wrong with the lighting on that side?”

Twilight latched onto the flimsy excuse, “Yeah, that’s it. The uh… light was in my eyes.”

Rain Whistle smirked and tickled Twilight playfully with her wing.

When the waitress came both mares ordered the Prench Onion soup and hot chocolate. While they waited they both talked about how the got interested in science and when their food did finally come, they scarfed it down in no time at all.

“It seems you two were hungry, long day of hard work?” The waitress asked casually.

“Oh, definitely,” Rain Whistle agreed enthusiastically, “Lots of work.”

Twilight nodded along intently but couldn’t hide the rising blush on her face, “Yeah, work.”

The waitress gave them a confused look before blushing slightly and stammered “Oh, well that’s good, yeah lots of work to do. Anyways can I interest you in any dessert?”

“Oh, I’m not sure I could eat any more.”

Twilight gave the pegasus a withering glare before turning back to the waitress.

“We’ll split a molten chocolate filled cookie.”

“Right, one molten chocolate cookie for the two les- ladies.”

The waitress then did her best to not run as she left the table after her slip up.

“Well, that was interesting.” Rain Whistle said, “And why are you so intent on desert?”

“Well,” Twilight looked down at the table, “It’s just that there is this book I read once, well maybe more than once, but in it when the main character goes on a date for the first time with her love interest, they shared dessert and I sort of have always wanted my first date to end like that.”

“This is the first time you’ve ever been on a date?” Rain Whistle asked, surprised.

“Yeah, a few of the colts at school have asked but I have always been busy,” Twilight said sheepishly, “and-”

“You only like mares.”

Twilight looked at her partner in surprise, “How did you guess? I mean you're right, but statistically speaking a vast majority of mares are bisexual with only a small few being exclusively homosexual.”

“Well, lets just say that both me and the waitress have picked up on some of the same vibes.”

“Oh.”

“Though she didn’t have to be such a prude about it.” Rain Whistle said gloomily.

“It’s not her fault,” Twilight replied in a sympathetic tone. “This is a high class establishment and discussing even unintentionally, one of the guest sex lives could lose her her job. Especially when the nobles that frequent these places tend to look down on and keep secret anything that isn’t purely a heterosexual relationship.”

“Wait, are you saying that she think we would get her fired to keep her quiet?” Rain Whistle asked.

“Well, not us specifically, but the normal types of ponies that come here.”

“That’s awful, what’s wrong with sex anyways? Everypony does it, even them.”

Twilight just shrugged.

A different waiter came out with their desert. Rain Whistle tried to take a bite out of it but Twilight pushed her back with her telekinesis, before scooping a generous amount of cookie and hot fudge onto her fork and sheepishly bringing it up to the pegasus’s mouth. Rain Whistle rolled her eye good naturedly and accepted the food, humming as the sweet flavor filled her mouth. When Twilight tried to reclaim the utensil however, Rain Whistle stole it out of her magic with a competitive glint and returned the favor. Twilight blushed as she ate off of the previously used fork. The two mares went back and forth until the entire plate was empty except for a few smudges of liquid chocolate.

The waiter did them the favor of not showing them the total and simply informed them that they could leave when they were ready. As they made their way to the exit Rain Whistle got a glimpse of their original waitress and when the two made eye contact, the pegasus gave her a reassuring smile and a wink.

When Twilight and Rain Whistle got back into the lobby, they were met with quite a problem however. The weather had continued to get worse and had turned into a late winter blizzard.

“We should have stayed at the table, maybe just spent the night.” Rain Whistle said as she stared forlornly out at the howling snow and ice on the other side of the door.

“Well, I can just teleport.” Twilight offered.

“You can teleport me all the way home?”

“Well, not exactly. I can only teleport to places I can see or places that I have a good memory of. So…”

Rain Whistle adopted a stern expression.

“Don’t you think it is a bit forward to invite a mare over after only the first date?”

“I-I mean I can take you to the castle and you can use a guest room instead” Twilight verbally backpedaled.

“I’m kidding silly.” Rain Whistle said with her usual charming smile. “I have this itch that I can’t quite reach anyways and I think you might be able to help.

Rain Whistle rubbed her stomach that was still somewhat bulging from the plant’s nectar and gave Twilight a hungry grin.

Twilight flung her arms around the pegasus and in a flash of light they disappeared.


Rain Whistle woke up to the quiet sounds of bird song and a few rays of light tickling her feathers. As her mind began to push away the fog of sleep she realized that her bedroom didn’t have any windows in it. With a little panic, Rain Whistle’s eyes shot open, only to be met by the half lidded gaze of a recently awoken Twilight Sparkle. The pegasus sighed in relief and sunk back into the mattress a little as Twilight pulled herself closer to her bed-mate.

“G’Morning” Twilight whispered groggily.

“Morning.”

Rain Whistle shifted her weight a little and then came to a startling realization. When the two of them had fallen asleep last night, the plant tentacle had been inside her pussy and as she started to stretch out, she could feel it still pushed deep inside her, stretching her out.

“Twilight, your plant is still inside me,” Rain Whistle complained.

“It’s okay, with us moving around,” Twilight yawned, “It should wake up soon and leave.”

And wake up it did, but instead of removing itself, the tentacle began to wiggle around and secrete its aphrodisiac into the two mares. Rain Whistle groaned in defeat as she felt her body heating up.

“We don’t have to do this if you don’t want to.” Twilight said even as she mentally berated herself for suggesting they should stop.

Rain Whistle looked into Twilight’s slightly pouty eyes and sighed.

“I don’t really have anything better to do.” She then smirked playfully, “Plus, you look cute with bed head.”

Twilight blushed at the compliment even as she leaned in and kissed the pegasus. Rain Whistle happily invited Twilight's tongue into her mouth. The mares’ lips pushed against each other as they enthusiastically traded saliva and the tentacle began to push back and forth between them. It was not long before they were moaning into each others’ mouths.

Rain Whistle scooted her lower body up against Twilight's until she could feel her pussy lips brush up against the unicorns. The tentacle retreated further into Twilight's womb until Rain Whistle had easy access to begin thrusting their lower lips together. Twilight moaned as the two mares clits brushed past each other. She shifted her legs so that she had more leverage as she pushed her hips into her partner’s.

The mares pulled and pressed at each other leisurely, even slowing down their kisses, as they enjoyed each other's embrace. Twilight massaged Rain Whistle wings. She ran her hooves through the feathers and pressed into the toned muscles along the edge. Rain Whistle returned the favor by stroking Twilight’s back and thighs. In turn paying special attention to her starburst cutie mark.

Twilight cooed as she quietly orgasmed and pulled Rain Whistle tight against her. The pegasus released Twilight’s tongue and instead gently licked along her ear and nibbled at the tender flesh. Rain Whistle gasped as Twilight pushed hard against her and mashed their clitori together. The sudden jolt of pleasure was enough to push the pegasus over the edge as well and join Twilight as she softly moaned and added her marecum to the mixture between their legs.

As they came down from their shared highes the two mares snuggled together, content to enjoy the afterglow in the tangles of each others legs.

“Well, I have woken up worse.” Rain Whistle said, finally breaking the silence.

Twilight hummed in agreement and rested her head against Rain Whistle’s neck.

“Your so soft and warm,” Twilight muttered against the pegasus’s plush winter coat.

In response, Rain Whistle draped her wing over Twilight's body. Twilight looked up at her with puppy dog eyes.

“Are you sure we can’t be marefriends yet?”

Rain Whistle giggled, “Not until the second date.”

“We should go to the park then after breakfast,” Twilight replied matter of factly. “You know, for our second date.”

“You sure are eager, aren’t you?”

“I like you, a lot. And plus the park looks nice in the snow, especially when it is sunny outside.”

“Alright then,” Rain Whistle acquiesced. “After breakfast.”

Twilight cooked up an omelette with cheese and bell peppers while Rain Whistle showered. The pegasus claimed that the breakfast was delicious but Twilight knew that she had over cooked almost everything. Even the milk was slightly warmer than it should have been. Ultimately, it mattered little to the two of them as they put on their cold weather clothes and trotted out into the snowy Canterlot streets.

Rain Whistle walked with a calm and relaxed gait but Twilight had a hard time not jumping up and down in excitement as they walked side by side. Every now and then, Twilight would accidentally bump into her companion; Rain Whistle would respond by giggling and playfully batting at Twilight’s flank with her wing.

Canterlot park was easily the largest city managed park in equestria. It boasted over a thousand different species of flora in the summer time and even in winter had an amazing array of both coniferous and deciduous trees though only small pockets of evergreens still had needles while the other trees had shed their leafy coverings and opted for a more seasonal plumage of fluffy white snow.

The two mares passed a group of foals sledding down one of the parks hills as they stepped into the bastion of calm wilderness and out of the still bustling city. They walked in silence as they made their way through the glistening wonderland of snow until they came to a more secluded hill that overlooked the frozen pond at the center of the park.

“You were right,” Rain Whistle said as she layed down on the soft snow. “It really is beautiful out here.”

Twilight laid down next to the pegasus and shift to make a comfortable resting place.

“Yeah. Me and Shining Armor would come out here all the time when I was little. We would sled and have snowball fights.”

“Who is Shining Armor?” Rain Whistle asked casually.

“Oh, he’s my older brother. He is a Lieutenant in the Royal Guard you know.”

“Wow sounds like quite an accomplished family you come from. You’re the personal student of the princes and your brother is an officer. I wish my siblings had that kind of drive.” Rain Whistle huffed. “One is a clerk at a supermarket and the other digs irrigation canals.”

“Both of those seem pretty important though,” Twilight replied.

“Yeah, but they're not happy about what they do. Not like you and I, pursuing our dreams.”

Instead of speaking, Twilight just pressed herself up against Rain Whistle and wrapped a foreleg around her as comfort.

“Enough gloominess though, we came to have fun right?” Rain Whistle said, her usually cheeriness returning to her voice.

Twilight looked over at her.

“What did you have in mind?”

“Well,” Rain Whistle gave Twilight a mischievous look, “I think you said something about a snowball fight, didn’t you?”

Before Twilight could respond, Rain Whistle had taken to the air with a flap of her wings and had also managed to bury Twilight under a half foot of snow. Not to be caught flat hooved, Twilight teleported out of the snow pile and began to collect ammunition. Rain Whistle did have a head start though and before Twilight could even get a bearing on the pegasus, a baseball sized chunk of snow splattered against her side.

“Too slow!”

Twilight grimaced with determination, a rarely felt competitive urge swelling inside her.

“Oh yeah?” she smirked. “You may be fast but I think you are forgetting something.”

As Rain Whistle prepared to throw again, her target suddenly disappeared in a flash of light. Twilight re appeared directly in front of Rain Whistle before pelting the pegasus with three point blank snowballs. Rain Whistle managed to get her wings up in time though and only took one hit to her chest before retaliating and hitting Twilight right in the face.

Shaking off the hit, Twilight quickly disappeared again. Rain Whistle collected more snow as she cautiously scanned her surrounding. She was caught off guard though, when several more projectiles hit her from above. When she turned, she caught glimpse of purple in the trees.

“So that’s how it’s going to be?” Rain Whistle jeered.

She scooped up a pile of snow and promptly took to the air. With the aerial advantage, Twilight couldn’t take a shot without exposing herself and though she did still get a fair amount of hits, she took just as many. The game ended abruptly when Twilight was hit as she poked her head out from around a tree. The snowball connected directly with her horn causing all of her ammunition to fall to the ground. Twilight herself curled up and started whimpering.

“Oh my goddess, are you alright?” Rain Whistle said with a voice full of panic. “I’m so sorry, please don’t be hurt.”

The pegasus was at Twilight side almost immediately and as she crouched down next to the stunned unicorn she could heer Twilight hissing.

“Horn f-f-f-freeze. Be okay s-s-s-soon.”

Rain Whistle draped her wing over Twilight and pulled the unicorn close. Twilight was rubbing her horn with her hooves to try and warm it up and stop the shooting pain. Unicorn horns were extremely sensitive in order to detect and feel out the magic around them but unfortunately made injuries, even minor ones, very painful.

“Here, let me help you.”

Rain Whistle moved Twilight’s hooves out of the way and brought her muzzle close enough to the unicorn's horn that it was almost touching. She then gentle exhaled the warm air from her lungs against the cold appendage. Twilight shivered as the hot air hit her but this time because of the numbing pain starting to release. Rain Whistle continued to blow against Twilight’s horn until the unicorns moans and whimpers subsided completely.

Twilight was about to get up but then she felt something entirely new against her horn. Rain Whistle had, entirely impulsively, wrapped her tongue around the base of Twilight’s horn and gently stroked the bony protrusion with the warm wet organ. Twilight moaned as the warmth filled her horn and travelled through the sensitive nerves into her head. Though not in pain any more, Twilight still whimpered as Rain Whistle started to pull away.

“Please… Do that again.”

Rain Whistle chuckled but complied and Twilight shivered as her tongue stroked her horn again. The pleasure caught Twilight off guard, she had gotten her horn wet before and even run the warm water of her shower over it. She had felt it clearly, but it had never made her feel so good like the sensation of Rain whistles licking did.

Twilight moaned as her body began to heat up. She instinctively rubbed her back legs and clenched her pussy wall together. The plant inside her felt the movement as well as the liquid arousal begin to build up in her inner passage and started to become active. It shifted and gently wiggled inside her as well as began to secrete more aphrodisiacal nectar. Twilight moaned and mentally praised the plant as it worked to increase her sexual need.

“Is this making you that horny?” Rain Whistle asked incredulously. “I mean, I knew unicorn horn were sensitive but wow.”

Twilight rolled onto her back and wrapped her forelegs around Rain whistle and pulled her towards her.

“Well, I am a huge slut now right?” Twilight purred.


“I suppose if we must head back and engage in more sex.” Rain Whistle replied in a faux put-upon voice.

Twilight though shook her head and pulled herself up to the pegasus’s face.

“No, I want you to fuck me right here until both of us pass out and then wake up under the stars and then fuck some more.” Twilight paused and placed a gently kiss right below the pegasus’s ear,speaking much softer. “And then finally when it is too cold outside, we will go back to my tower and make sweet love to each other until we fall asleep.”

Rain Whistle couldn’t help but blush.

“That is very speci-”

Before she could finish her sentence, Twilight had claimed her lips and sent her tongue into Rain Whistle’s mouth. The pegasus returned the kiss for a moment and then pulled back.

“Twilight, we can’t have sex out in the open like this.”


Twilight huffed in aggravation. Her hower lips were practically on fire now and she needed something to rub them against.

“First of all there is nopony here and second there is actually no law against public fornication.”

“Realy?”

Twilight answered by replacing her lips on Rain Whistles and eagerly continuing their make out where it had left off. With less reservations, Rain Whistle reciprocated and allowed Twilight to drag her down on top of her. When Twilight broke away, Rain Whistle leaned up and began licking her horn again slowly and sensually. Twilight in turn kissed and licked at the pegasus’s neck and chest as well as occasionally softly biting her. Still it wasn’t enough though as her womb filled with the alluring burn of the plants lustful fluids.

Twilight fired up her horn, which sent sparkle flavored tingles across Rain Whistles tongue. She used her telekinesis to push the other mare down all the way so that there stomachs met and pushed pleasantly against one another. Rain Whistle took a bit of initiative and interlocked their back legs. Both mares cooed as their nethers met. They slid easily against each other and Rain Whistle felt the nectar that was being forced out of Twilight start to burn pleasantly against her pussy as well.

As they began to push harder and harder against each other, the two mares mouths met again. They sloppily sucked down each other’s saliva as their tongues danced and carassed each other. Twilight was already close to her peak with both the external stimulation to her swollen vulva as well as the plant’s tentacle rhythmically pushing up and down her passage way.

Their clits brushed against one another’s.

Twilight came.

She squirted her pleasure all over her own lower body as well as Rain Whistles. Twilight pulled back and laid her head against the snow as her walls clenched down on the tentacle inside her. She moaned as Rain Whistle continued to grind against her, stimulating her already overstimulated nerves.

For her part, Rain Whistle gently lapped at Twilight’s horn as the unicorn orgasmed. Twilight moaned as her pussy convulsed again in a second mini orgasm.

“I don’t want to sound greedy,” Rain Whistle said cheekily as Twilight’s shuddering ended, “but do you think you could share some of that plant with me?”

“I don’t really control what it does though,” Twilight said apologetically.

After she finished speaking though, Twilight did half heartedly try to will the plant to extend its tentacle and to her surprise, It did. The tip poked just outside of her snatch. Thinking it was a fluke, she willed it back in. The tentacle retreated back to her cervix.

“Or maybe I can control it?”

Rain Whistle gave her partner a look of half confusion and half hope. She didn’t have to wait long before she felt the tentacle press against her own pussy. Before it entered though, it sprayed more nectar up into her. Twilight smirked as Rain Whistle sighed at the returning feeling of mind numbing lust.

“More please, and deeper.” Rain Whistle begged, hoping to feel the hopeless horniness that she had in the lab yesterday.

Twilight complied and Rain Whistle moaned as the tentacle pressed up into her. She sighed contentedly as the tip nestled up against her cervix. The nectar forcing its way into her womb sent euphoric heat through her. Even before the tentacle had finished, Rain Whistle was desperately thrusting against Twilight’s hips again. Twilight, already lost to her own arousal eagerly returned the motion and both mare moaned again before locking muzzles mouths again.

It didn’t take long for either of them to reach their climax and they both orgasmed at the same time. The squirmed and held each other tight as their combined marecum soaked their lower bodies. Twilight latched onto the pegasus’s wings and kneaded them relentlessly even as she held the mares tongue captive between her lips.

Both mares soldiered through their climax as if it was just a bump in the road and continued to grind needily. On Twilight’s command, the tentacle started pumping in and out of them. Every time it pushed roughly against her cervix. Rain Whistle would gasp inside their kiss. Twilight couldn’t stop moaning quietly as the tentacle pushed and pulled against her walls. Using a little imagination she told the plant to turn like a cork screw inside them. Both mares gasped at the change and came again.

The tentacle added its own contributions to their free flowing fluids and helpfully reignited the sensitive nerves of their pussies with fresh nectar. The liquid even flowed over their clits, causing the bundles of pleasure to stiffen almost painfully.

Rain Whistle happily ground her clit against Twilight’s even as the pleasure of climax continued to flow through her. The spike in stimulation made Twilight experience an immediate second orgasm. She was forced to break away from Rain Whistle and gasp for breath as her pussy walls started to convulse all over again.

Instead of licking her partners horn, Rain Whistle took the entire protrusion into her mouth. As she massaged it lovingly, Twilight howled in pleasure. She continued to squirt as a third climax took a hold of her. When the convulsions ended, Twilight quietly drifted off to sleep. Rain Whistle grumbled as the tentacle retreat instinctively from her and back to it home in Twilight womb.

Still horny beyond belief, Rain Whistle gently laid Twilight on her side before scooting against her and thrusting her fold against the unicorn's back. It wasn’t anything amazing but it was enough to get off one last time before fading away as well.

~~~~~

Twilight awoke embraced in warmth. Rain Whistle legs were wrapped tightly around her and the pegasus’s wing was draped over her body. As Twilight shifted her head out of her curled up position, her nose brushed against one of the feathers making her sneeze.

“Good evening my slutty little unicorn.”

Twilight looked up at the sky and the stars were in fact out, framed by a few wispy clouds against a canvas of the deepest blue and purple.

“How are you feeling?” Rain Whistle asked before gently kissing the unicorn's neck and jaw.

“Great...” Twilight replied easily,

Twilight sighed as she felt her body begin to heat up again.

“Very Horny.”

“Is that so?”

Twilight cooed and pressed back against her partner as she felt a hoof trail down her body and rest atop her still wet folds. She moaned as Rain Whistle softly rubbed her flower and carefully flicked her clit. Every now and then, the pegasus inserted just enough of the tip of her hoof to be satisfying and not teasing.

“Can we be marefriends now?” Twilight asked before gently climaxing again.

“Depends, can you put that tentacle back inside my needy cunt?”

Rain Whistle shivered as her hoof was pushed aside by the advancing plant. It expertly snake up the valley of Twilights ass, pressing against the muscular ring of her anus on its way pas and deftly penetrated the pegasus’s plump pussy.

“It would be my pleasure.”

Chapter the Fifth

Twilight moaned as Rain Whistle removed the head of the flask from her pussy.

“Was that as good for you as it was for me?”

Twilight chuckled and walked back to the work bench.

“I don’t know, did you get enough liquid?”

Rain Whistle swirled the pink sticky mixture around the inside of the flask.

“Yeah, this should be enough for the next test. I guess it is pretty convenient that you can just make this stuff at will.”

“It’s not that simple,” Twilight replied. “The plant feeds off the magic produced when ponies, specifically mares in this case, have sex. The more liquid I use up, the less control I have over the plant.”

“Interesting. What a strange relationship.”

“Indeed. I assume that if I went too far, the plant would end up forcing me into sex at some point, but I don’t know. Of course, the plant stores all of its excretions as magic and with how well we have kept it fed, I could probably fill my entire bathtub before that happened.”

“That would be quite a sight for sure.” Rain Whistle agreed.

When she was answered by only silence though, Rain Whistle turned away from her workstation to check on her marefriend. Twilight was diligently transferring the results of previous experiments to their official log, but with her tail raised and out of the way, the pegasus had an unfettered view of her hindquarters. The tip of the plant tentacle was sticking out of her pussy, which was leaking arousal. Though with constant and increasing exposure to the aphrodisiac, both mares were almost always aroused and wet. The tentacle was sticking out just enough to curl up to Twilight's anus and firmly massage itself against the tight sphincter.

“Please tell me you aren’t planning on trying this out?”

Twilight casually reached around and pulled on her ass cheek to help open up her puckered star. The tentacle pushed itself in and Twilight sighed as she stretched around the intrusion.

“Want to join me?”

Rain Whistle shook her head. “As much as I love doing kinky stuff with you, I think I’ll let the results of this specific experiment come in first before I give it a go.”

“Aww. Well, more for me I guess,” Twilight giggled. “I promise I’ll think of you.”

“No you won’t.” Rain Whistle said with a smirk. “You will be thinking about how much you want all of your slutty little holes filled with plant nectar to the point of bursting.”

In response to the comment, the tentacle pushed much deeper into Twilight’s ass making her groan.

“Yeeeeeeaaaah…”


As soon as Twilight got home, she rushed through the house to ensure Spike wasn’t home. Most week days he stayed in the castle as part of his developmental program but Twilight wanted to be sure she wouldn’t be interrupted. After clearing the house, Twilight locked all of the doors and windows and put up a teleportation ward. Obviously it couldn’t keep the princess out, but it would let Celestia now that Twilight wanted to be left alone.

With that all done, she laid a liquid proofing spell over the entire house. There was no telling how messy this would be so she wanted to be sure. With everything accounted for, Twilight eagerly climbed into her rather large bathtub, one of the perks of living on the castle grounds.

Twilight laid on her back with her head resting on the rim of the tub. She mentally commanded the plant to start producing its nectar and instantly was rewarded by a deep tingly and burning in her womb and passage. Twilight reached down with her hoof and gently kneaded her lower lips as more arousal and nectar flowed out of them. She couldn’t help but sigh as she became hornier .

The burning lust had become a comfort to Twilight and her entire body relaxed even as it prepared itself for sex. Twilight wasn’t even sure how she would have dealt with not being at least somewhat aroused all the time. It was a comforting presence that helped wash away her fears and anxieties. Additionally, the pleasure of her pussy lips brushing against each other as she walked and the feeling of her own arousal drying against her inner thighs was always exquisite.

As Twilight contemplated her perverse sexual desires her hoof pushed harder against her pussy and with a moan she spilled out the first of what was about to be a lot of marecum. The plant, sensing that Twilight was adequately worked up and willing, stopped filling her with its aphrodisiac. Twilight mental pushed against it, pleading for it to keep going. Reluctantly, more nectar began to spill out and Twilight giggled in anticipation. She mentally promised the plant that when this was all over she would let go of her control and beg it to do anything and everything to her. Surprisingly, though the plants surprises were become commonplace, the plant seemed to understand and be enticed by this arrangement. More and more nectar spilled out, faster than ever before. It was enough pressure to stimulate Twilight’s wall. She instinctively clenched against the outpouring of liquid to try and increase the pleasure. All she accomplished was turning it from a leak into a concentrated spray from her pussy. Twilight groaned as the fast moving liquid tore across her erect clit. She came again, adding an insignificant amount of her own juices to the rapidly growing pool of aphrodisiac.

The Tentacle pushed itself out of Twilight’s snatch and began to fill the tub directly as she recovered from her climax. Her relaxed breathing helped to work the quickly growing aroma of the plants nectar into her lungs. She took as deep of breaths as she could to make sure that as much of the aphrodisiac got into her body in as many ways as possible. She even grabbed the end of the tentacle and sprayed it into her mouth. After swallowing several mouth full, she could feel the warm contents of her stomach begin to absorb into her body and add to the fiery lust as well.

The pool of nectar now covered her entire groin and almost hid all of her cutie mark as well. Interestingly enough, even her exposed skin was becoming hot and itchy for stimulation. Twilight pressed her hooves into her flanks and groped her own ass cheeks. She moaned as it sent waves of pleasure through her body.

Eager to get started but not wanting to lose control until the plant was finished, Twilight mental urged it to speed up. In turn, she felt something stir deep inside her. In just a moment, more nectar spilled out from around the tentacle and the tub filled faster. At the same time, Twilight could feel her link with the plant start to fade. She tried to hold onto it while simultaneously waiting anxiously for the moment at which it would break.

Twilight slid deeper into the tub as the liquids reached her shoulders. Her head sank into the nectar until only her eyes and nose were above the surface. The liquid rushing out of her pussy combine with the squirming in her womb and the thick tentacle spreading her open all quickly brought about another orgasm. Twilight writhed in the debaucherous fluids causing some to splash over the sides of the tub. The constant exposure to the plant’s fluids had also made her much more sensitive and it was easier than ever for Twilight to climax.

As usual, but to a magnified degree this time, Twilight’s need for sexual stimulation only grew as she clenched down against the tentacle and came. With the last spasm of pleasure she felt the plant slip completely away from her mind. The tentacle wasted no time and quickly pushed its tip up against her anus. At the same time it thrust back and forth out of her pussy. Twilight moaned as the tentacle forced itself into her again and clenched her sphincter tight. The resistance as the tentacle forced its way further and further up her ass was mind blowing.

Twilight felt herself squirt almost immediately and as the tentacle pushed further and further it got much thicker as well. In a flash of clarity, she realized that the Plant must also be conserving its own mass as magic in order to grow so large without tearing her womb apart. Before she could start getting distracted by the science, Twilight took a mouthful of nectar and swallowed it greedily.

Thankfully the tentacle didn’t let up either even after another climax and more waves of indescribable pleasure. As Twilight’s need grew, her pussy began to feel more and more empty. Despite the tentacle being larger than ever, she wanted something to stretch her out more. Twilight mentally begged the plant for more but it just kept thrusting along. She climaxed again but it was incconsequential in comparison to how horny she was. In desperation she pushed her hooves up against her mound and mashed against her clit.

The spikes of pleasure were welcome. Her pussy’s need to be filled further though grew exponentially. Twilight’s thoughts began to run together. Eventually everything became an image of more tentacles filling her holes. Twilight whined as she thrust against her own hooves. She couldn’t even tell when she orgasmed again.

Eventually, desperately, Twilight turned over and stood up in the tub. Instinctively she thrust out ass as if presenting to a mate. She shook and pushed her backside out as far as she could and let her entire head sink into the tub full of nectar. Finally, she felt something inside her stir again.

There was a new pressure on her cervix from within. Twilight let out a submerged moan as her inner barrier was stretch further again. A second tentacle began to press its way into her passage from her womb. The feeling of her cervix being stretched as it submitted to the new tentacle was exquisite. When Twilight pulled her head up to breath she cooed and orgasmed harder than ever before.

Twilight rocked her hips in time with the pulses of pressure and drooled as the tentacle stretched her further Each tiny bit that her cervix gave caused Twilight to clench her pussy walls, slowing the tentacle’s progress. Twilight didn’t care because feeling her body slowly submit was ecstasy. She stretched out her back legs more and did her best to relax, letting out little squeaks and squeals every time the tentacle drew further out of her. Twilight mentally begged for the tentacle to sunder her inner barrier.

As soon as the tentacle finally made its way past her inner barrier, Twilight happily squirted her pleasure into the liquid below. Her legs locked up and her moans joined the sounds of the tentacle ravaging her pussy along with her cum splattering into the fluid. As soon as the second tentacle emerged it pressed itself up against Twilight’s clit. She came again immediately and fell onto her stomach in the fluid filled tub.

As she came down from her high, the tentacle snaked its way across her body. It rubbed sensually against her matted fur before circling her neck and presenting itself to Twilight’s mouth. She gratefully accept it, lavishing it with her tongue. Instead of feeding her nectar though, the tentacle pushed a fine breathable mist into her mouth. Twilight eagerly inhaled it and delighted in the feel of the aromatic aphrodisiac filling her lungs. The mist was better suited to being inhaled and giggled as she became even more deliciously horny.

With her breathing accounted for she sank deeply into the liquid filled tub and bucked back against the two tentacles as they pistoned inside her holes. Even the one in her mouth pressed itself deeper into her throat and thrust in rhythm.

Twilight hugged herself and gently rolled back and forth in time with the pleasure. She came again and sighed contentedly into the nectar bath. Before it could become routine though, the two tentacles stretched away from each other to try and open up Twilight's pussy even wider. Feeling another tentacle pushing up against her cervix, Twilight stretched her back legs out and apart as far as she could to try and help it get through. She hissed in need as it got more and more forceful. Thankfully, the plant had also been exposing Twilight to chemicals that would help her body stretch and recover painlessly. The third tentacle pushed its way past her cervix and down her passage spreading the other two further apart and igniting another climax.

Instead of following the second tentacle, this one travelled along her back. It passed between her ears and gently curled around Twilight’s horn. She gasped as the tentacle rhythmically squeezed her. Twilight raced towards her next orgasm. This time as cum spilled from her, she poured out magic uncontrollably as well. The tentacles shimmered and turned from blue green to lavender. Twilight orgasmed again as a fourth tentacle pushed out of her. It looped up and firmly pressed itself against her anus as well. Twilight orgasmed a third time when it forced its way in.

As the plant absorbed more magic from Twilight’s horngasms, a fifth tentacle grew and quickly pushed its way out of her womb. Twilight gasped and choked as her body continued to shudder. She could feel her her entire pussy stretched beyond belief and could only hope for more. Her womb swelled as the plant grew more and more.

Thankfully, The tentacles had some give to them. As a sixth tentacle emerged Twilight couldn’t stop herself from trying to clench down on the spongy appendages. With how filled she was though, she made little progress. The feeling of having so little control over her body was bliss to Twilight. A new pressure built at her cervix and growing frustrated at Twilight’s unintentional hindrance, the last two tentacles wrapped around her hind legs. They stretched her legs as far apart as possible and finally thick bulges began to pass down the tentacles.

Twilight moaned as thick gel erupted inside her ass. It was much thicker than the nectar and it made her burn much more too. As the tentacles continued to fill her back door, a seventh tentacle appeared and moved up to join the one at Twilight’s lips. With, all the stimulation, Twilight came and came again. The new substance was making her so much more sensitive. Between gasps, Twilight managed to open up for the new tentacle and it quickly entered her awaiting mouth.

She swallowed as hard as she could to help The tentacle as it pushed down her throat, past the one that was giving her air. It finally stopped above her stomach and began feeding her the thick gel as well. It was impossible now for Twilight to stop what was happening. She didn’t want to; she couldn’t want to. Every fiber of her being told her this is where she needed to be. She would cum. The plant would consume the magic. The plant would feed her to keep her horny. And she would cum again.

It was perfect.

Twilight’s mind blanked out at the euphoria.


Twilight didn’t know how long it had gone on for but only that it had felt like heaven the entire time. Now though her mind was clear. Her body was floating in a sea of sexual discharge and at the welcome mercy of more than half a dozen tentacles. Her stomach was as big and tight as an expectant mother. Her mind though had become detached. The pleasure was a distant, warm, breeze: comforting, but an afterthought.

It was in this moment that Twilight realized something.

Sex is the magic of creation, but wielded by ponies.

Her vision filled with stars.


“I still don’t like it,” Cadence said with a troubled sigh.

“Certainly your not jealous of her are you?” Celestia replied, shading her eyes from the afternoon sun. “I mean, what about you and Shining Armor?”

“I’m not Jealous. Well, maybe a little.” Cadence admitted sipping her tea casually. “Me and Shiny haven’t.. You know.”

“Had sex yet?”

Cadence rubbed her forehead in frustration.

“Yeah. But that not my point. I don’t want her to get hurt. This Rain Whistle is six years older than her.”

“She’s a good pony though.” Celestia wrapped a forehoof around her niece, “You know I wouldn’t let Twilight get into any big trouble right?”

“Yes, I know that. I just don’t think being that sexually active is healthy.”

“Well I lost my virginity at eleven. It’s not uncommon for alicorns to be sexually active at a young age.” Celestia snickered. “In fact Twilight was a bit late.”

Cadence gave Celestia a confused look, “What do you mean alicorn?”

Realizing what she had just let slip, Celestia wisely introduced her face to the small tea table.

“Wait, is Twilight? Oh goddess this is great news!”

“Cadence, you can’t tell anypony, not even her.” Celestia quietly pleaded.

“Of course. It could interrupt her ability to ascend, like with Sunset Shimmer.”

“Yes, and we don’t even know what her domain is.”

“Well at this rate,” Cadence said sarcastically, “It will probably be-”

The two princesses were interrupted by a flash of brilliant lavender and magenta light filling the room.

“Princess Celestia, Cadence, You won’t believe what just happened.”

Both alicorns turned to Look at the excited unicorn. Standing at the other end of the balcony was a slightly taller Twilight Sparkle, with wings spread proudly.

“Twilight!”

Celestia leapt from her chair and swept Twilight up in a hug.

“I’m so proud of you!’

“Thanks princess. I couldn’t have done it without you.”

When Celestia finally set her student back down she summoned another chair and beckoned for Twilight to join them.

“So, my most faithful student, what is your domain? Magic? Alchemy? Knowledge, perhaps?”

“Or maybe books?” Cadence added teasingly.

“Well actually,” Twilight replied with a smile, “It’s a lot like Cadence’s. We’re almost like alicorn sisters.”

Thud

“Oww”

Celestia looked over at where Cadence had taken a turn at face to table introductions-

“It’s Sex!”

-and joined her soon after.
