	Celestia awoke that morning with a rather odd feeling. She knew something about this day was off, but she couldn’t quite put her hoof on it. No matter, she still had duties to perform. Walking into the throne room, her guards gave her an impeccable stance as usual, but she couldn’t help noticing their eyes were wide and darting back and forth between each other. A guard she already passed could be heard shuffling around just slightly. She paid this no mind, as it was probably just another rumor they tossed around once in a while.
As she approached the breakfast hall, she saw Luna also headed for some breakfast before she went to sleep. Greeting Luna, they walked together in silence until Luna could stand it no longer. 
“Dear sister, art thou okay?” 
Stifling a giggle, Celestia replied, “Oh Lulu, you always revert to the traditional Canterlot language when you’re tired. And of course, why wouldn’t I be?”
Bumping her sister’s flank playfully as they walked, Luna reminded herself she needed to watch how she talked around her sister. Celestia took every opportunity to poke fun at her, over the simplest things.
Luna had noticed the way her sister smelled was quite different than her usual vanilla scent, and the effect it had on her guards was plainly obvious. After a moment of silence, Luna finally mustered up the courage to ask, “Tia…are you…in heat?” She blushed fiercely after asking this, and couldn’t stop herself from turning her head away as she walked. 
So that’s what it was. That’s why this day was feeling off to Celestia. She managed to keep her mind off of it, but now that it was so obviously put in front of her, there was no dancing around it any longer. Those guards, their strange looks, all of it made since now. And now there was nothing she could do about it. 
Or so she thought. Shaking her head, remembering she hadn’t yet replied to Luna, she cleared her throat and muttered, “Oh, dear. I guess…I guess I am. I felt something was off when I woke up, but I didn’t know what it was exactly.” Sighing, she continued on. “But now that you mention it, I have roughly a few hours before it kicks in completely and I’ll want to…ahem, rut…anything in sight. I’ll inform the guards in the throne room to cancel all requests for me, and I’ll spend today in seclusion.”
“But sister, you know as well as I do that doing so is very unhealthy. Why don’t you send for Twilight? She’s just a few halls away, I’m sure she’ll take some time away from her newly-acquired princess-y studies to help…you know.” Luna looked pitifully at her sister, feeling empathetic towards her situation. Sometimes being a princess wasn’t easy, and times like this were a perfect example why. 
Pondering for a moment, Celestia began to think of how Twilight could help her. It would most definitely sedate her heat cycle before things got too out of hoof, and by the stars, it’d feel absolutely amazing. It had been so long since Celestia had any kind of relief, in that sense. Quite a long time, almost certainly longer than any normal mare would be able to withstand. 
Arriving at the breakfast table broke her thoughts, and Luna sat next to Celestia, putting a wing around her elder sister. 	Celestia shuddered at the touch, and realized how soft the pillow beneath her rump was. Ever so slightly pushing herself into it, she contained a whimper and did her best to keep a straight face. Luna didn’t let it slide however, she noticed exactly what happened. So she ordered a nearby guard to send for Twilight Sparkle to be addressed directly to Celestia’s personal chambers as soon as breakfast was over. The guard raised an eyebrow, but ended up nodding and returning to his post for the time being.
Ears pinned back at this point, Celestia whimpered to Luna, who was having none of it. Luna knew exactly what her sister needed, and couldn’t bear to see her in such a miserable state. The waitress arrived with their favorite breakfasts, both steaming hot and freshly cooked on this fine morning. For Luna, she ordered something more on the side of a dinner, as this actually was her dinner just before bed. A plate of fettuccine alfredo, along with a few boiled carrots and a small salad sat in front of her, as Luna licked her lips in anticipation for her meal. For Celestia, she preferred a smaller breakfast than most, so her breakfast consisted of two sunny-side-up eggs, (no pun intended) and some French toast with a bit of syrup. Celestia wasn’t exactly hungry just yet, given her situation, but she hurriedly swallowed every last bit, and finished off her orange juice. Excusing herself, she hastily made way for her chambers, determined to give herself relief before Twilight showed up. Maybe if she sated herself, she could tell Twilight her sister was just over-reacting. Although, Celestia couldn’t lie, she wanted it extremely bad right about now.
Several strange looks from her guards later, she entered her personal chambers. Relieved that she didn’t pounce on anything on the way back, she removed her crown, neck regalia, and finally, her golden shoes. Not wasting another second, she lied down on her bed and relaxed. All of a sudden, her nether region sparked into life. She gasped, no longer able to resist putting a hoof down there. Slowly rubbing up and down her moistening sex, she whimpered lightly and thought to herself, “Why can I not stop…I’ve never had this much trouble in the…past…Oh by the stars, this feels…so good…” There was no stopping now, until she finished at least. Knowing Twilight would be here in the next few minutes, she began to rub faster, teasing her entrance and causing her to wink uncontrollably. She then moved up to her clit, and upon coming in contact with it, she let out a quiet moan and continued rubbing it forcefully.
Despite all of the pleasure she was giving herself, she couldn’t stop her mind from wandering. She thought of everything bad that could happen in the next half hour, and even worse, she feared that Twilight would be horrified and storm out of the room. She tried shaking the thoughts out of her head as she kept rubbing harder and harder, going faster to try and keep her mind in the right thoughts. Proving that to be no help, she slowed down as tears began to form in her eyes, the frustration finally getting to her. Celestia was scared, no doubt about it. Stopping altogether, she just flipped over and cried silently into her pillow. Remembering Twilight would be here very soon, she was about to get up and make herself look presentable. All of a sudden, as her mind made up this thought, a knock on the door, followed by a guard allowing Twilight inside, scared Celestia. Sniffling and not moving from her spot, she was almost unnoticeably trembling, as she quietly said, “Come in, Twilight.” 
“Princess…? Is everything okay?” Twilight slowly approached Celestia’s bed, and upon noticing her trembling, she put her hoof on Celestia’s back and nuzzled her the best she could. Although, now she was this close to Celestia, she could smell a rather musky, desperate odor, and could only imagine what went on in this bed within the last twenty minutes. But now, her beloved ruler was crying and shaking. Permission or not, she was going to comfort Celestia if it was the last thing she did. Hopping up on the bed, she lifted Celestia’s face off the pillow and caressed her cheek, wiping away the tears gently.
“Celestia, look at me. I’m here to help you with whatever you need, okay? But to do that, I’m going to need you to tell me what’s wrong, and to trust me.” Twilight whispered gently.
Nodding, Celestia sniffled once more, and readjusted herself to a more comfortable position. She hadn’t stopped trembling yet, but she did her best to hide it. Clearing her throat, she began to speak. “My dear Twilight, I’m sorry you had to see me like this. I assure you, I’ll be fine with some rest. It was merely a nightmare.” Her voice was shaky and sounded almost heartbreaking to hear. 
“Now, you know as well as I do that isn’t the case at all. You wouldn’t have had time to fall asleep upon returning from breakfast, let alone start dreaming long enough to startle you into such a state. So, if you’re not going to tell me yourself, I’ll just tell you that I already know what’s bothering you.”
“Y-you do…? But Twilight, it’s only been five minutes since you’ve been in here. There’s no way you could possibly kn-“ Celestia was cut off by Twilight, as she pushed her lips into hers. Making Celestia go wide-eyed, she relaxed into the kiss. Her former faithful student had the most incredibly soft lips she had ever felt, although that number wasn’t very high. She could count on a single hoof how many ponies she’s kissed. 
Twilight’s tongue slowly parted her lips, reigniting the fire in her twitching marehood. Celestia tried to rub her hind legs together to sedate the burning itch, but that only made it worse. She moaned into Twilight’s mouth as their tongues danced together, fighting for dominance. Eventually, the need for air suppressed the lust temporarily, as Twilight bit Celestia’s lower lip gently, pulling away. Celestia was panting, and couldn’t deny the pleasure that was slowly building up again.
“So…still think I don’t know?” Twilight smirked, waiting for Celestia’s reply. A blush crept across her face, as she lowered her head into Twilight’s chest. Finding a perfect opportunity, Twilight kissed her beloved princess on the forehead, and feeling adventurous, kissed the base of her horn as well. This elicited a sharp gasp from Celestia, jumping up from her comfortable position. 
“Twi…Twilight…Please, help me out of this, err, rutting mood…I need you Twilight, you’re the only pony I’d trust enough to do this. Other than Luna of course, and you know I’d never do that to my sister.” She whispered, with a few pants in between.
That was all Twilight needed to hear, and she gently rolled Celestia onto her back, and exposed her soft, fuzzy belly. Kissing it, Celestia let out a quiet, cheerful giggle. “Twilight! That tickles!” 
Twilight planted one more kiss on her tummy before moving down to her abdomen where her perfectly-hidden teats slowly perked up. She gently slid her tongue right in the middle of them, causing Celestia to shudder and whimper just slightly. By this time, Twilight’s marehood was slowly starting to moisten itself, making Celestia twitch and shiver under her fuzzy purple lover. Twilight took one of the now exposed pink nipples between her teeth and gently suckled it, making sure to run her tongue across the very top for good measure. Hearing Celestia’s squeals and pleasured moans, she decided to switch to the other one, when suddenly a soft, white hoof on her forehead stopped her.
“Twilight…please, wait. I-I can smell your arousal and it’s driving me crazy. I absolutely must use the bathroom…smelling another’s sexual desires, well…you know what that does to us mares. I’ll only take a minute.” 
Smirking, the purple alicorn placed a hoof right on Celestia’s urethra and pressed in. Rubbing slowly and holding the larger princess with her body weight, she simply whispered, “No. You’re a big pony, you can hold it.” Upon saying this, she rubbed faster to help the poor mare contain herself.
Celestia groaned as she shivered, slowly feeling her bladder fill even farther. She instantly regretted not using the restroom before succumbing to her desires. Twilight was down by her soaking marehood, tending to her needs, but with a hint of teasing as well. She moved slowly, other than the hoof pressed against her urethra to help her hold it in. She suckled on one teat at a time, licking them, and caressing them with her nose. This sort of teasing was beginning to be too much for Celestia, and finally she cried out, “Twilight…please! I can’t wait any longer…”
Her main reason for begging wasn’t the pleasure, but for the burning desire to let her bladder lose. She was losing control as her sphincter muscles began relaxing due to Twilight’s now-gentle rubbing. A mare in heat generally can contain herself, but upon smelling the arousal of another pony, has to rush themselves to the nearest restroom, or secluded area, to relieve themselves. And now, Twilight was denying her the release she so badly needed. A part of her was aroused due to that, but the other part desperately wanted to just let loose. Whimpering, she tried to grind her hips into Twilight’s hoof, which pulled away at that very moment. Instantly, she thrust her hoof down to hold herself, realizing how much Twilight’s hoof had actually helped. Celestia was visibly shaking now, much more than she had since Twilight entered. The smaller alicorn kissed the white hoof now rubbing forcefully, and removed it with her magic. Celestia quickly clenched her legs shut, to try and help the pressure subside. With a cheeky smirk, Twilight took her hooves and rubbed up the sides of Celestia’s flanks, moving to her abdomen. 
Once she reached the now swollen part that caused her beloved princess so much agony, she gently massaged it. The pressure of it being pushed down was too much for Celestia, as she begged for Twilight to let her go. Twilight did stop rubbing her swollen bladder, just so she wouldn’t be in pain, but that didn’t stop her from moving down to her quivering sex and letting out a warm breath against her clit. Celestia moaned quietly and began to move her hips, as if she was trying to hump anything that came into contact with her. Wanting Celestia to calm down and let her do the work, Twilight placed a hoof on her crotch and gently pushed her down, and giving her one last look of endearment, placed her muzzle right on her clit, also taking in her throbbing urethra. Celestia’s back arched as she cried out in pleasure, her marehood now winking constantly below Twilight’s muzzle. Twilight moved a hoof to the desperate hole, and quickly rubbed it. She had a better idea though, one that would surely help the oversexed mindset of the sun princess. 
Conjuring up things with magic was not a new study for the former librarian, so she easily summoned up a fairly long and thick vibrator, with rotating pearl-like balls taking up a little under half the insertable length. Keeping her muzzle attached to her clit to keep Celestia from letting her bladder loose everywhere, she slowly lowered the dildo to Celestia’s aching slit. Turning it on a moderately low setting, she slid it up and down the leaking hole. Finally letting her clit loose, she lifted her head to see Celestia’s back arched and wings splayed out. Seeing Celestia in such an arousing position, as well as the given circumstances, drove Twilight insane. Deciding to conjure up another vibrator, she cast the spell. Not wanting anything large, she went with an egg-shaped vibrator that slipped inside her, while attached to another egg-shaped vibrator for her clit. With hers in place, she went back to attend to Celestia. But, she decided enough agony was enough. She crawled up to Celestia’s abdomen and sat down, causing the larger mare to wince in pain. Twilight had laid the vibrator down, so nothing was aiding her predicament, and it was everything she could do not to let go on her sheets. 
With Twilight sitting on her abdomen, Celestia felt the vibrations coming from Twilight’s toy, which made her bladder twinge and beg to be emptied. She grimaced and huskily whispered, “Twilight…I can’t hold it anymore…”
Twilight crawled up closer to her, and kissed her muzzle lightly. She then whispered into Celestia’s ear, “Just let go, let it all out…” And as she said that, she placed her magic against Celestia’s slit, allowing her to release into a magical barrier that prevents any sort of mess. Upon hearing permission to release, Celestia’s bladder had enough of holding. She sighed in complete relief as the pain in her abdomen subsided and left her body. The relief of letting go caused her vaginal walls to wink once more, now even more sexually aroused. 
Once she finished, Twilight’s magic suckled every last drop off of her to ensure cleanliness, and Twilight sent the filled orb to the toilet. Feeling much better, Celestia was able to fully relax to whatever Twilight wanted to do. Twilight crawled up even closer to Celestia, and gently leaned in for a kiss. It didn’t last long however, since Twilight pulled away to focus her attention elsewhere. She wanted to see what would happen if she paid special attention to her horn and wings, so that’s exactly what she did. Using her magic to massage her wings and preen her feathers, she licked Celestia’s horn from the base all the way to the tip, making sure to listen attentively for any special reaction. 
As she continued however, it wouldn’t take much listening to hear the quite obvious moaning coming from Celestia’s muzzle. Deciding to suckle on the tip of her horn, Twilight kept massaging her wings, but moved the dildo to her marehood and held it against her clit. The low, teasing vibrations on Celestia’s clit drove her wild as she began bucking forward in a further effort to push it inside. With Twilight tending to her horn, wings, and aching marehood, Celestia wanted to return the favor, so she reached up with her hooves and while one hoof ran along her spine and the base of her wings, the other gently pushed and pulled the toy in and out of Twilight, eliciting several moans from her.
Not wanting to be outdone, Twilight ran kisses down Celestia’s belly and planted a kiss on each teat before reaching her slit once again. This time, she gently pushed the dildo inside of Celestia, slowly to avoid hurting her, and turned the power up about halfway. The sudden change of speed drove Celestia wild, causing her to buck her hips forward and arch her back. Finally being filled almost sent her over the edge as she whimpered and moaned, begging for more.
“Unh…TwiliIIIGHHTT!” Her speech formed into a scream halfway through, when Twilight turned the speed all the way up inside of her, causing the pearls to rotate even faster against her swollen g-spot, and the vibrating head to buzz harder against her cervix. 
“Do you want me to move it for you, Tia?” 
“Yes, Twilight…That feels so…good…I need more…” Celestia panted.
Twilight pulled it out, agonizingly slow, and left just the tip inside. She decided to give one final tease before she gave 	Celestia the best orgasm of her life. “Say please.”
“Please…please Twilight, I need it so bad, rut me with that thing!”
That was more than enough Twilight needed to hear. With one quick motion, Twilight thrust the vibrator all the way inside of her, and pulled it out, only to thrust it inside yet again. Every once in a while, she’d allow some of the pearls to rotate against Celestia’s entrance, which caused Celestia to squirm and moan. Twilight didn’t want to leave any area of Celestia untouched, so she used her magic on the dildo to keep it thrusting in and out at exceedingly fast speeds. That alone drove the alabaster pony wild, but to make matters better, Twilight turned her own vibrator up to the highest speed and sat on Celestia’s crotch, causing the egg on her clit to be shared with Celestia’s clit. 
“Oh, Twilight…please don’t stop…mmmm…yes…”
Twilight gyrated her hips and made the clit vibrator move around on Celestia’s clit, along with leaning forward to kiss the horny mare. Their moans being exchanged between each other’s mouths, Celestia broke the kiss with a slight pant and croaked out, “Twilight, I’m really close…” 
“Cum with me Celestia, let’s both feel better, together…” Twilight continued pushing herself into Celestia’s clit, so that the vibrator between them drove both of them crazy. She was still rutting her with the dildo as fast as she possibly could, faster than any stallion could ever move his hips by far. Both of them were moaning sensually and rapidly approaching their climax.
Their movements were becoming quick and desperate, and Celestia suddenly cried, “I’m cumming, Twilight, oh please, don’t stop!”
In a last ditch effort to make the beautiful mare beneath her have a longer orgasm, Twilight rapidly rubbed against Celestia’s clit with the vibrator against her own, sending her over the edge as she screamed, “Oh Celestia, yes! Cum with me!”
Twilight collapsed onto Celestia’s chest, panting with exhaustion and pleasure. Celestia sighed with relief that her estrous cycle had been sedated, and wrapped her forelegs around the adorable mare on top of her. 
“Thank you, Twilight.” Celestia whispered.
While lying on top of Celestia, Twilight asked, “Why were you crying earlier, by the way?” 
“I’ll tell you when we wake up. But don’t worry; you already crumbled the thoughts that upset me. Promise.” The two nuzzled together as they dozed off for a nap, both happily relieved and exhausted.

Sniffling and not moving from her spot, she was almost unnoticeably trembling, as she quietly said, “Come in, Twilight.” 
“Princess…? Is everything okay?” Twilight slowly approached Celestia’s bed, and upon noticing her trembling, she put her hoof on Celestia’s back and nuzzled her the best she could. Although, now she was this close to Celestia, she could smell a rather musky, desperate odor, and could only imagine what went on in this bed within the last twenty minutes. But now, her beloved ruler was crying and shaking. Permission or not, she was going to comfort Celestia if it was the last thing she did. Hopping up on the bed, she lifted Celestia’s face off the pillow and caressed her cheek, wiping away the tears gently.
“Celestia, look at me. I’m here to help you with whatever you need, okay? But to do that, I’m going to need you to tell me what’s wrong, and to trust me.” Twilight whispered gently.
Nodding, Celestia sniffled once more, and readjusted herself to a more comfortable position. She hadn’t stopped trembling yet, but she did her best to hide it. Clearing her throat, she began to speak. “My dear Twilight, I’m sorry you had to see me like this. I assure you, I’ll be fine with some rest.

“Y-you do…? But Twilight, it’s only been five minutes since you’ve been in here. There’s no way you could possibly kn-“ Celestia was cut off by Twilight, as she pushed her lips into hers. Making Celestia go wide-eyed, she relaxed into the kiss. Her former faithful student had the most incredibly soft lips she had ever felt, although that number wasn’t very high. She could count on a single hoof how many ponies she’s kissed. 
Twilight’s tongue slowly parted her lips, reigniting the fire in her twitching marehood. Celestia tried to rub her hind legs together to sedate the burning itch, but that only made it worse. She moaned into Twilight’s mouth as their tongues danced together, fighting for dominance.

Finding a perfect opportunity, Twilight kissed her beloved princess on the forehead, and feeling adventurous, kissed the base of her horn as well. This elicited a sharp gasp from Celestia, jumping up from her comfortable position. 
“Twi…Twilight…Please, help me out of this, err, rutting mood…I need you Twilight, you’re the only pony I’d trust enough to do this. Other than Luna of course, and you know I’d never do that to my sister.” She whispered, with a few pants in between.
That was all Twilight needed to hear, and she gently rolled Celestia onto her back, and exposed her soft, fuzzy belly. Kissing it, Celestia let out a quiet, cheerful giggle. “Twilight! That tickles!” 
Twilight planted one more kiss on her tummy before moving down to her abdomen where her perfectly-hidden teats slowly perked up. She gently slid her tongue right in the middle of them, causing Celestia to shudder and whimper just slightly. By this time, Twilight’s marehood was slowly starting to moisten itself, making Celestia twitch and shiver under her fuzzy purple lover. Twilight took one of the now exposed pink nipples between her teeth and gently suckled it, making sure to run her tongue across the very top for good measure. Hearing Celestia’s squeals and pleasured moans, she decided to switch to the other one. 
“Twilight…please, don’t tease…” 
Smirking, the purple alicorn placed a hoof right on Celestia’s clit and pressed gently. Rubbing slowly and holding the larger princess with her body weight, she simply whispered, “No. You’re a big pony, you can wait.” Upon saying this, she rubbed faster to help the poor mare contain herself.
Celestia groaned as she shivered, this sort of teasing was beginning to be too much for Celestia, and finally she cried out, “Twilight…please! I can’t wait any longer…”
Once she reached the now swollen marehood that was leaking constantly, Twilight let out a warm breath against her sensitive clit. Celestia moaned quietly and began to move her hips, as if she was trying to hump anything that came into contact with her. Wanting Celestia to calm down and let her do the work, Twilight placed a hoof on her crotch and gently pushed her down, and giving her one last look of endearment, placed her muzzle right on her throbbing bud. Celestia’s back arched as she cried out in pleasure, her marehood now winking constantly below Twilight’s muzzle. Twilight moved a hoof to the desperate hole, and quickly rubbed it. She had a better idea though, one that would surely help the oversexed mindset of the sun princess. 
Conjuring up things with magic was not a new study for the former librarian, so she easily summoned up a fairly long and thick vibrator, with rotating pearl-like balls taking up a little under half the insertable length. Keeping her muzzle attached to her clit to keep Celestia on the absolute edge, she slowly lowered the dildo to Celestia’s aching slit. Turning it on a moderately low setting, she slid it up and down the leaking hole. Finally letting her clit loose, she lifted her head to see Celestia’s back arched and wings splayed out. Seeing Celestia in such an arousing position, as well as the given circumstances, drove Twilight insane. Deciding to conjure up another vibrator, she cast the spell. Not wanting anything large, she went with an egg-shaped vibrator that slipped inside her, while attached to another egg-shaped vibrator for her clit. With hers in place, she went back to attend to Celestia. But, she decided enough agony was enough. She crawled up to Celestia and sat down, causing the larger mare look up questioningly. Twilight had laid the vibrator down, so nothing was aiding her predicament, and it was everything she could do to avoid pouncing on the purple pony. 
Twilight crawled up closer to her, and kissed her muzzle lightly. She then whispered into Celestia’s ear, “You look so beautiful when you’re like this…” And as she said that, she placed her muzzle on the tip of Celestia’s ear and nibbled gently. The strange, new sensation caused her vaginal walls to wink once more, now even more sexually aroused. 
She wanted to see what would happen if she paid special attention to her horn and wings, so that’s exactly what she did. Using her magic to massage her wings and preen her feathers, Twilight licked Celestia’s horn from the base all the way to the tip, making sure to listen attentively for any special reaction. 
As she continued however, it wouldn’t take much listening to hear the quite obvious moaning coming from Celestia’s muzzle. Deciding to suckle on the tip of her horn, Twilight kept massaging her wings, but moved the dildo to her marehood and held it against her clit. The low, teasing vibrations on Celestia’s clit drove her wild as she began bucking forward in a further effort to push it inside. With Twilight tending to her horn, wings, and aching marehood, Celestia wanted to return the favor, so she reached up with her hooves and while one hoof ran along her spine and the base of her wings, the other gently pushed and pulled the toy in and out of Twilight, eliciting several moans from her.
Not wanting to be outdone, Twilight ran kisses down Celestia’s belly and planted a kiss on each teat before reaching her slit once again. This time, she gently pushed the dildo inside of Celestia, slowly to avoid hurting her, and turned the power up about halfway. The sudden change of speed drove Celestia wild, causing her to buck her hips forward and arch her back. Finally being filled almost sent her over the edge as she whimpered and moaned, begging for more.
“Unh…TwiliIIIGHHTT!” Her speech formed into a scream halfway through, when Twilight turned the speed all the way up inside of her, causing the pearls to rotate even faster against her swollen g-spot, and the vibrating head to buzz harder against her cervix. 
“Do you want me to move it for you, Tia?” 
“Yes, Twilight…That feels so…good…I need more…” Celestia panted.
Twilight pulled it out, agonizingly slow, and left just the tip inside. She decided to give one final tease before she gave Celestia the best orgasm of her life. “Say please.”
“Please…please Twilight, I need it so bad, rut me with that thing!”
That was more than enough Twilight needed to hear. With one quick motion, Twilight thrust the vibrator all the way inside of her, and pulled it out, only to thrust it inside yet again. Every once in a while, she’d allow some of the pearls to rotate against Celestia’s entrance, which caused Celestia to squirm and moan. Twilight didn’t want to leave any area of Celestia untouched, so she used her magic on the dildo to keep it thrusting in and out at exceedingly fast speeds. That alone drove the alabaster pony wild, but to make matters better, Twilight turned her own vibrator up to the highest speed and sat on Celestia’s crotch, causing the egg on her clit to be shared with Celestia’s clit. 
“Oh, Twilight…please don’t stop…mmmm…yes…”
Twilight gyrated her hips and made the clit vibrator move around on Celestia’s clit, along with leaning forward to kiss the horny mare. Their moans being exchanged between each other’s mouths, Celestia broke the kiss with a slight pant and croaked out, “Twilight, I’m really close…” 
“Cum with me Celestia, let’s both feel better, together…” Twilight continued pushing herself into Celestia’s clit, so that the vibrator between them drove both of them crazy. She was still rutting her with the dildo as fast as she possibly could, faster than any stallion could ever move his hips by far. Both of them were moaning sensually and rapidly approaching their climax.
Their movements were becoming quick and desperate, and Celestia suddenly cried, “I’m cumming, Twilight, oh please, don’t stop!”
In a last ditch effort to make the beautiful mare beneath her have a longer orgasm, Twilight rapidly rubbed against Celestia’s clit with the vibrator against her own, sending her over the edge as she screamed, “Oh Celestia, yes! Cum with me!”
Twilight collapsed onto Celestia’s chest, panting with exhaustion and pleasure. Celestia sighed with relief that her estrous cycle had been sedated, and wrapped her forelegs around the adorable mare on top of her. 
“Thank you, Twilight.” Celestia whispered.
While lying on top of Celestia, Twilight asked, “Why were you crying earlier, by the way?” 
“I’ll tell you when we wake up. But don’t worry; you already crumbled the thoughts that upset me. Promise.” The two nuzzled together as they dozed off for a nap, both happily relieved and exhausted.
