Friendship Lesson

View Online

Today was a nice sunny day, as usual. You, the human, wore a plain short-sleeved white t-shirt, blue shorts, and brown sandals. You were having a relaxing day. Nothing crazy was happening for once in this magical horse land. You ventured forth into Ponyville Park to avoid nosey ponies. You would like to stay at your new home in the Golden Oak Library, but ponies had a terrible habit of walking in on you, even if you were using the bathroom. You didn’t own the library. The unicorn known as Twilight Sparkle allowed you to stay there by the kindness of her heart; it seemed.

The library wasn't a perfect place to live. For ponies didn't seem to grasp the concept of privacy, even though you had your own ‘private’ room… in the basement. This was particularly the case with Pinkie Pie. Who often came to check up on you while you were in a compromised position, such as trying to masturbate in peace. That was mighty embarrassing. Thankfully, she never seemed to tell anyone about it.

Anyway, on this quiet day in the park, you could only hear birds chirping, and the distant laughter of pony children. There was a mild breeze in the air, which helped you cool off a little during this hot day. You were sitting on a park bench along a paved path while reading a book. Your dear friend Twilight Sparkle recommended this book. It was quite an exciting book. It was about an adventurer pony known as Daring Do. This Daring Do mare kind of reminded you of Indiana Jones.

Yep. Today was going to be perfect. No crazy little horse shenanigans today. Just you and your book. The loud, silly pony Pinkie Pie was busy at work at Sugarcube Corner, so even she was not here to bother you today.

“There you are!” screamed a familiar voice, along with a loud clopping sound. It appeared she was trotting toward you. You could hear her hooves hitting the paved path hard below.

You exhaled deeply. “I spoke too soon.”

You lowered your book to see your friend Twilight Sparkle had a crazed look in her eyes as she stood before you. Twilight’s eyes were twitching erratically, darting from left to right, and sometimes spinning around in a circle. The unicorn mare’s pupils had become shrunken into tiny marbles of purple. Her mane was a complete mess, and she was sweating profusely. Her body itself seemed to radiate heat. There was a psychotic smile on her face.

You whimpered in fear. Twilight was quite scary today. Normally you are not afraid of Twilight. But today was a different story. It seemed she had lost her marbles.

“Thank Celestia, I found you! I’ve been looking all over for you! Surely you, the only human in Equestria, must have a friendship problem!” she said, tilting her head to the side. This came accompanied by a sickening bone-cracking sound. The psychotic smile on her face made it all the more creepy.

Nervously, you scratched the back of your neck with your right hand. “Uhh, maybe? I dunno.”

Twilight neighed loudly in frustration, lifting her two front forelegs high into the air, before she slammed her hooves on the paved path with an earth-shattering kaboom. A cloud of dust was created from the hard impact of her hooves hitting the path. You could see her hooves had dug deep into the path from the sheer force of the impact.

You whimpered in fear. Twilight was immensely strong. Despite being only about 4 feet tall, or so. This little horsey could tear you limb from limb if she wanted to. “Come on! You are the only human in Equestria! You must have some sort of friendship problem!” she shouted.

“Twilight! Go suck my dick! I just want to be left alone!” you shouted.

Twilight gasped in joy, her right hoof coming to her mouth. You could see the pupils of her eyes enlarging. It was as if she was on drugs. “That’s it! I’ll go suck your dick!” she lunged at you, jumping onto your lap. You winced in pain when her rump landed on your lap. You ended up dropping your book on the path below. She was quite heavy for a little pony. The mare laid her soft, spongy feeling hooves on your shoulders. Her rather plump rump rested directly on your crotch. It was warm and soft to the touch. Only a thin layer of clothing prevented you from touching it. Her body in general radiated heat as if she was a mild radiator. Her ass was particularly hot in temperature.

You smiled nervously at Twilight as she looked at you with a psychotic grin on her face. Normally, Twilight was a very nice mare. “Uhhhh, Twilight, what are you doing?” you asked, giving her a questioning look.

“Well, I want a kiss first before I suck your cock.”

“Twilight, I don’t feel that way about ponies. I was only joking about you sucking my dick.”

Her right eye twitched and she glared at you angrily. “A joke?! A joke?! This is serious, Anon! My life depends on sucking your cock!”

“Surely you can't be serious…. right?” you said, before giving her a nervous smile.

Twilight neighed in frustration. “Neeiigghh! Anon! If I don’t suck off your cock today, I won’t have a friendship lesson! Princess Celestia will banish me to magic kindergarten! You’re my only hope! Help me! Please allow me to suck you off like a good friend!”

“Uhhh, don't you think you're overreacting a little?”

Twilight growled angrily, flaring up her horn with magic with a deep pink glow. “I AM NOT OVERREACTING!” boomed her magically amplified voice. You cringed as your ears rang painfully. Unlike you, I'm not a lazy bum that lives on welfare!”

“Hey! That hurt my feelings, Twilight!” you said in a bitter tone, narrowing your eyes at her.

“Then let your friend suck your dick as a form of an apology. Please, I want to suck your cock. I’ll do anything for you, my friend. I’m sorry for calling you a lazy bum.”

You were happy Twilight wasn’t that forceful, even in this deranged state of mind she was in at the moment. At least she was asking. Twilight could if she wanted to just force herself on you. She had magic and was far physically stronger than you.

You thought about saying no, but you didn't want Twilight to go completely insane. It seemed she really needed to suck your dick. You were not going to leave your friend dry by leaving your dick dry. “Okay, Twilight. Just be… gentle, please,” you said in a low voice.

Twilight made a sound like a dog’s chew toy in happiness. “Of course, I will be gentle. Now, give me a kiss before I suck your cock.”

“Here in the park? Should we not go somewhere more private?”

“Public intimacy is perfectly legal in Equestria. Although if we hold hooves… err… Or hand and hoof we will get funny looks. While not illegal, it is frowned upon.”

“Oh, I see.”

“Shut up and kiss me, my human friend!” she demanded, wiggling her soft, warm, plump rump over your crotch. You gasped at the feeling of her rump. You found yourself quickly gaining an erection, a rather large one of that. An 'O' shape came over her mouth, before the mare giggled, her right hoof coming to her mouth. “You do like ponies, huh?”

You felt your shorts become damp. There was also an odd musky, yet fruity smell in the air. “Uh, Twilight? Are you okay?”

She smiled nervously and began to sweat profusely. The mare tapped her two front hooves together, fidgeting nervously. “I’m so sorry about being so forward with you. I just need a friendship lesson, and I am in the middle of my estrus cycle.”

You pondered for a moment to think. Twilight Sparkle was a very intelligent unicorn with connections to royalty as Princess Celestia's personal student. You may end up set for life being her partner. If you were going to fuck a pony, it might as well be a socially awkward bookworm. Besides, she is really cute, and also she’s technically your landlord, so you could pay rent by fucking her. It was a viable survival strategy to enter a romantic relationship with this crazy little pony. You were going to stick your dick in crazy.

So, with all that considered. You leaned forward to leave a soft kiss on her lips for a brief moment. Her lips felt warm and soft, and slightly fuzzy against your own. You pulled back to gaze at her reaction. The mare's cheeks lit up with a pink blush and she beamed happily at you.

“Oh, Anon. Do you want to help me during my estrus? That could be a good friendship lesson instead.”

“If it means you don't go crazy, sure. I don’t want my friend totally losing her marbles.”

Twilight squealed happily as her eyes sparkled with joy while clapping her two front hooves together. “Awesome!” she said in an excited voice, placing her hooves back down on your shoulders. “You are a true friend. I'll suck your cock all the better now, my good human friend.”

She gave you a psychotic smile, overjoyed that you were here to help her during her estrus.

“Looking forward to it,” you simply said, giving her a smile of your own. A nervous one of that.

Twilight whimpered with delight before she lunged forward, her lips locking with yours. Her large equine tongue came to enter your mouth and swirled about, completely dominating your far smaller one. You could only lick the underside of her larger tongue for the most part. Her breath smelled minty fresh. It seemed she had brushed her teeth before arriving here. It was almost as if she had anticipated you would end up kissing her.

You could hear the mare utter a muffled giggle when her tongue brushed over your semi-sharp canine teeth. You could only guess she liked the hint of danger. Unlike you, she was a vegetarian for the most part. Apart from chicken eggs, she ate them too. Eggs were your only source of protein for the most part here. Well, not exactly, Fluttershy gave you fish and grounded up bugs to eat. Normally, you don’t like bugs, but you had little choice here. You also had milk to drink. A cow’s milk was a bit awkward since it came from a sapient minded creature. Cows were intelligent here, and could speak. You pray a cow never learns you ate beef burgers on Earth.

During the kiss, you raised your hands up and placed them upon Twilight’s lovely, plump backside around her cutie marks. Your hands sank into the plush bubbly softness of her rear. Deep beneath, you met her strong muscles. Her cheeks were soft and warm to the touch. The mare uttered a muffled giggle into your mouth when she felt your hands upon her ass.

Her tail swished from side to side during her excitement. It was quite an adorable sight. You were warming up to the prospect of doing the deed with a pony. Twilight was probably far more intelligent than you. Actually, you were pretty sure she was. For her teacher, Princess Celestia was thousands of years old.

The two of you kissed for quite some time before you eventually pulled apart. A strand of both of your respective saliva came to fall as you slowly departed lips. The two of you were panting heavily from the entire ordeal. The mare stared at you with dreamy eyes.

“That… that… that was wonderful, my friend,” she said in a blissful tone.

“You’re… you’re welcome, Twilight.”

Affectionately, she leaned forward to leave a tender kiss on your lips with a wet smooching sound. The mare then pulled back and gave you a warm smile. You lifted your right hand away from her rump and raised it upward toward her face. The mare leaned into your hand and sighed happily. She seemed a little less crazy now, and more relaxed.

“Twilight, before we proceed further, can we do this someplace else more private?”

“Sure thing. Let’s go.”

The two of you stood up and made your way to leave the park. As you walked, Twilight kept close to you, rubbing herself against you as if she was an affectionate cat. Her tail wagged back and forth, lightly brushing off against you. In fact, she was quite literally purring like a cat. You chuckled at this, shaking your head.

You too soon crossed the bridge and came to enter Ponyville. The ponies of the town seemed to be quite happy to see that you managed to get a mare. The ponies smiled at you and cheered at you in celebration. The only notable exception was Lyra Heartstrings, who had a heartbroken look on her face with her jaw dropped.

You then saw Lyra rush back inside her home. You then could hear the distraught mare wailing in grief from inside.

“Poor Lyra,” Twilight said quietly, coming to a stop. You did the same. “She has feelings for you. Do you want her as a marefriend as well?”

“Er, Twilight. I’m kind of a one-woman man.. errr… one-mare.”

Twilight’s ears drooped sadly. “Oh, you’re one of those selfish monogamous types.”

“Twilight most humans are monogamous. Jealousy is inherent to most humans.”

“What’s there to be jealous about? A herd normally consists of a single stallion and his marefriends. It's very rare for there to be two stallions in the same herd. Since most stallions are stableosexual.”

“Stableosexual? What’s that?”

“It means you are only attracted to the opposite sex. Most mares tend to be openbarnosexual. An openbarnosexual are attracted to both sexes. It’s very rare for a mare to be a stableosexual. There are also samebarnosexuals, who are only attracted to the same sex as their own.”

“Ahhhh! Stop it with the horse puns! It hurts!” you said sternly, rubbing your forehead with your right hand.

A single tear fell down her cheek. “I always wanted to be the lead mare of a herd. But I guess, that will never be now.”

You sighed deeply. “Okay, okay. I may give it a chance someday. But I’m not willing to just jump in bed with somepony. I need to get to know them first.”

Twilight rolled her eyes. “Anon, you’ve only been here for about a week. And you are already willing to jump into bed with me.”

“I… I-I..” you sighed. “You got me there.”

Twilight gently tapped your thigh with her hoof. “It’s okay. We can take this slow if you want. Sorry, if I come across as trying to rush you.”

“It’s okay, Twilight. I should be delighted that you want to drown me in pussy. I don't think any human woman, at least where I used to live on Earth, would behave like you.”

“Mares like to share their stallion among friends. It helps build good relationships, “ she sighed deeply and looked at you with an imploring look. “I do hope you will have sex with my five best friends as just friends for the very least.”

You were quite confused. You have not even done the deed with Twilight yet, and already she wants you to fuck her friends; Pinkie Pie, Rainbow Dash, Applejack, Fluttershy, and Rarity. This magical little horse world is so strange. Then again, she is an alien.

“I’ll think about it,” you simply said.

The mare simply nodded. But you could tell she was a little upset by your answer. Her floppy ears folded back, indicating she was sad. Without a word, the two of you made your way toward the Golden Oak Library.

This building stuck out like a sore thumb when compared to the rest of the Western European mediaeval architecture of the town. In a sea of thatched houses, a huge ass oak tree stood near the centre of town. The building literally carved into a tree had many balconies and windows. The front door was dark red. The tree was quite inviting.

Twilight pushed open the door with her right hoof and stepped inside. You quickly followed behind her. The interior of the building was pleasant. It was warm and cosy. It was not remotely damp, nor filled with nasty insects. The downstairs entrance room was a wide-open space circle. You could see many shelves carved into the wooden ‘walls’ of the tree. These shelves had many books neatly stacked upon them. In the centre of the room, there was a circular table with a small oak tree stump as a support structure, instead of legs. There were some passageways in this room that lead to other parts of the tree.

On the ceiling of the room, there was a large yellow, spiralling, yet non-moving sun. It glowed like a lightbulb, giving light to the room. It appeared to be made of some sort of yellow crystal-like substance. From what you could gather, ponies did not use electricity for the most part. Everything seemed to be powered by magic crystals. Everything from the lightbulb, the oven, electric toothbrush, (or crystal-powered toothbrush in their case) to even very primitive computers was powered by this mysterious crystal material.

You were thankful that this world wasn't a total mediaeval shithole. They still have many modern appliances. Some key things that were missing were cars, aeroplanes, fast computers, the television, the microwave, and of course the Internet.

On the right side of the room, there was a staircase. Twilight trotted up the stairs, and you followed up after her. You had to duck your head, the passageway upstairs was quite narrow. Thankfully, it opened up once you reached the top of the stairs.

Sure enough, upstairs was yet another library. Albeit far smaller. This place had many bookshelves lining the walls of the room. It had a fireplace on the opposite side of the room to you. On the left side of the room, there was yet another staircase, but it was a much shorter one. Halfway up the stairs, there was a telescope pointing outside a window. You have never been up here, it was quite nice. Your ‘bedroom’ was the dark and gloomy basement of this tree, where Twilight kept all her crazy machines and other strange stuff.

Twilight turned around to face the short passageway of the staircase you came up. She lit up her horn with a deep pink glow and created a magical ward over the upstairs passageway. This ward was a deep pink colour like that of her horn’s magic. It was thin and transparent, so you could see-through the other side.

“There. That should stop any nosey pony from–” as she spoke you saw a pink blur dash across the room, and then suddenly Pinkie Pie appeared standing next to her on the right. The pink earth pony mare had a big happy smile on her face as she looked at you. “Oh... never mind.”

“Can I join?” said Pinkie Pie in a hot steamy voice, winking at you seductively.

You sighed deeply. “You just had to jinx it.”

Twilight turned around to face you. Her ears drooped sadly. You could see her lower lip quivering, and tears welling up in her eyes.

“Does this mean, you don’t want to– Hhhuuuh?” you cut her off, by kneeling down to give her a hug, your arms wrapped around her shoulders, touching off her lower back, just shy of touching her rump. Your head came to rest against her silky soft mane. The mare uttered a happy, quiet whinny, and she affectionately began to nuzzle your neck. “Oh, Anon,” she said in a quiet, relieved tone.

“Can I have a hug too?” said Pinkie Pie, looking at you with sad puppy dog eyes, while quite literally whimpering like a dog.

“Pinkie, should you not be working?” you asked.

“Eh, I can do two things at the same time,” Pinkie darted off like a pink blur, disappearing from sight, before reappearing again a moment later. “See?”

“Sorry, Pinkie. I want some alone time with Twilight.”

“Awww!” she whined sadly. “Well, if you ever change your mind. Just ask. And I’ll come. My eyes and ears are everywhere. I'm always listening and watching.”

Then the two of you witnessed a very disturbing sight. Pinkie Pie dissolved into a puddle of pink goo. This goo subsequently slipped through the floorboards underneath and vanished from sight. Both you and Twilight had a shocked look on each of your respective faces over what had just transpired.

“Okay, that was rather freaky. Should I even ask what happened?” you said in a low voice.

Twilight shook her head dismissively. “No. She’s Pinkie Pie. I’m not even sure she’s a pony sometimes.”

Twilight walked toward the staircase leading to what you could only assume was her bedroom. She swayed her hips from side to side, causing her thick, bubbly buttcheeks to create a light clapping sound of flesh, slapping against flesh.

You rushed after her, you wanted ‘dat ass’. Sure enough, Twilight lay on the bed presenting her rump to you. She looked back at you with a sultry look in her eyes. She shook her ass from side to side, creating more of that lovely meaty clapping sounds as her asscheeks smacked together.

You could not suppress your erection from the sight. Your shorts became very tight as your cock roared to life. You quickly pulled your pants down to let your member free, only to find it had grown much larger than normal.

“Uh, Twilight, did you cast some freaky spell on my junk?”

“No. You are a human in Equestria. I read books about your kind having huge, godlike cocks.”

“You read a lot of porn?”

She smiled sheepishly, her cheeks lighting up with a pink blush. “Yeah. I don’t have the best luck with stallions. But you seem nice.”

You were shocked at hearing this. Who could not love this cute bookhorse? You quickly took off the rest of your clothes and left them on the floor. You then lay yourself down on the crescent moon and starry themed bed next to her on the right. The mare positioned herself over you and laid her two front, soft hooves on your shoulders. She then lightly sat herself down upon your crotch. In doing so, your member ended up being hotdogged between the wonderful softness of her asscheeks. Her rump was pleasantly heavy as it lay upon you.

A strong musky smell was in the room. Her soaking wet marehood dripped profusely on your lap. The mare closed her eyes and began to grind herself over you, moaning in bliss, and uttering quiet horsey whinnies.

You raised your hands up and planted them upon her lovely rump’s cheeks, around her cutie marks. Subsequently, your hands sank into the plush, bubbly softness of her asscheeks like that of soft pizza dough. You could still hear her buttcheeks lightly clapping together as she continued to shake her ass. At the same time, her wildly jiggling cheeks came to smack against your cock. Your hands soon met her strong muscles underneath the thick layer of soft, lovely bookhorse booty.

Your only thoughts were. “God fucking danmit! Her ass is hot!”

Cheekily, you decided to pull your right hand away. You watched in delight as her asscheek resumed a perfectly smooth shape like that of a lake from your hand’s absence, like that of memory foam. With a show of force, you applied a hard slap upon her rear, causing her buttcheek to smack against the other one with a loud meaty slap, and also earning yourself a loud neigh of bliss from your unicorn lover.

The mare opened her eyes and stared at you with dreamy eyes. “If I suck your dick now. Will you return the favour? I need a gentlestallion to take care of my heat.”

“Of course, Twilight,” you said softly.

The mare giggled happily, and also made a sound like a dog's chew toy. Then the mare stood up, walked backwards, and positioned herself between your legs. An ‘O’ shape came over her mouth as she stared with dreamy eyes at your massive erection looming over her.

You breathe deeply, anticipating her affection. You reached your right hand down and brought it toward her cheek. The mare leaned into your hand, and sighed happily, her cheeks lighting up with a pink blush. The mare stared up with love and affection behind those big purple eyes of hers. Her big purple eyes stared into your very soul, into your small, human eyes.

None of you wanted to say anything. Saying something could spoil the moment.

The mare decided to show her gratitude for your affectionate gesture by leaning down and bringing out her long and thick equine tongue to oh-so lovingly lick the midsection of your long and thick cock. You gasped, your legs slightly jerking from the wonderful feeling. The mare giggled happily from your reaction.

The mare felt encouraged, and thus she began to apply a series of loving licks upon your member, soaking it with her warm saliva. You panted heavily at the feeling, and moaned in bliss, your hand upon her cheek came falling to your side. The mare between your legs for her part was moaning with hunger as she eagerly licked your member.

The mare stared up at you, to gaze at your reaction. When she saw the look of ecstasy on your face she giggled happily and continued her work. Inch by inch she worked over your member, making sure it was wet and slick with her saliva. Eventually, she decided to lift her head toward the thick tip of your member. She withdrew her tongue and leaned forward to plant a soft kiss on the tip with a wet, smooching sound.

You grunted, your legs kicking weakly at the feeling. The mare giggled with her right hoof over her mouth at your reaction. Without further ado, the mare leaned down to capture the tip of your member in her absolutely incredibly soft mouth. You gasped, your legs kicking weakly again. You almost felt like you had an electric shock from the sheer feeling of her wonderful mouth. The mare uttered a muffled giggle around her mouthful before beginning to slowly descend over your member.

Your head fell back, and you closed your eyes. You closed your mouth to muffle your scream of bliss. This was just Twilight, an inexperienced mare. And she wanted to share you with her friends. It was almost as if her mouth itself was laced with magic to amplify the feeling.

Inch by inch, her head gradually descended, her soft pony lips sliding along your member as she did so. You soon could feel your member going down her throat, and down into her oesophagus. She went further and further down, until she reached the very bottom, her lovely pony lips coming down to kiss your large grapefruit-sized balls with a loud smooching sound.

The mare lovingly held your member in her mouth and down her neck. You could see a huge bulge in her neck. The mare swallowed hard around her mouthful, creating a wonderful sensation of tugging and releasing. You moaned helplessly at the feeling. The mare uttered a muffled giggle in reaction around your thick cock.

Encouraged, the mare began to lift her head agonisingly slowly, sliding her soft lips along your cock as she did so. Her tongue came out of her mouth, affectionately licking your lower shaft as she slowly raised her head upward.

Once she reached the top of your member she began to make the slow journey downward again, licking your cock all the while she did so. Rinse and repeat she did this over and over again. You were a quivering mess, your whole body was shaking. The mare was content to suck you off this way. She uttered muffled moans as she slowly, and tenderly sucked you off.

At some point, the mare stopped moving. She held your member down around your base. Her large purple eyes looked up at you. You could tell she was wanting an answer from you.

“You’re… a good girl… Twilight. Keep going,” you said in a low, weak voice.

The mare uttered a muffled, happy giggle around your shaft, and went back to work. Gradually the mare began to pick up more confidence, slowly becoming faster and faster with her sucking. Soon, loud slurping could be heard as the mare bobbed her head up and down your long cock.

If that wasn’t enough, Twilight’s horn lit up with a magical, deep pink glow. You could now see a transparent magical deep pink ring appear at the bottom of your cock. This magic ring felt warm and soft like a woman’s hand against your member.

With a flick of her magic she began to quickly move the ring up and down. You were now effectively being sucked off and receiving a handjob at the same time. You quickly placed your right hand over your mouth to stop yourself from screaming at the wonderful feeling.

With both her mouth and her magic ring combined you found yourself quickly succumbing. Twilight dismissed the magic ring and pulled her head back, taking your cock’s tip into her mouth just in time. With a cry of pure bliss you unleashed a massive explosion of your creamy human spunk into her mouth.

Twilight eagerly swallowed down your cum with a loud gulping sound. You delivered spurt after spurt of your thick creamy human spunk. The mare soon became overwhelmed by the sheer amount of your cum pouring out of your cock.

Subsequently she quickly dropped her head down and took you all the way down her throat. She swallowed hard around your member, this came with a wonderful sensation of tugging and releasing, which coaxed you to unleash additional spurts of your cum.

You were only too happy to deliver volley after volley of your seed. Eventually though, your waves of cum became less and less, until they eventually stopped. Your whole body was twitching from the whole ordeal. Your member began to slowly soften in her mouth and down her throat.

Twilight did not seem too happy about this. She quickly began to bob her head up and down in an attempt to rekindle your erection. Your cock soon answered the call and subsequently began to re-harden.

The mare squealed in joy around your cock. She slowly lifted her head and released your member with a loud pop. Your cock stood primed and ready for more action.

"You stay here. I'll be right back. I need to find Spike and write a friendship report."

"Sure thing, Twilight."


Twilight’s voice could be heard speaking.

Dear Princess Celestia,

Today I learned that sucking off my human friend’s huge cock is a great stress reliever. I was very stressed out today, and my human friend helped me in my time of need. I am heading back upstairs to do further friendship studies with him. Soon, I will let you know the results.

Your faithful student,
Twilight Sparkle
