It was a particularly warm spring day, and Princess Celestia exited her carriage the moment it pulled up outside of Twilight's own castle doors. The proud princess walked toward toward those doors, full of confidence in her long elegant dress. Those beautiful translucence locks streaming behind her. Celestia's personal guard performing the routine escort, as they lead her into the custody of Twilight's own personal guard. It was something she never wanted, but was given regardless. Though as few as these visits were, it was typical for them to act this way.
Celestia managed to maintain her composure around them, clearly something was up with her. Though the princess was internally struggling against her own growing lust. The royal princess was hiding a certain tool, and while it was fully grown - it was stuck against her thigh, throbbing angrily. So far the meat-stick had remained hidden all day, but quickly the princess was getting restless. She needed to blow off some steam. Celestia panted gently, her breathing growing more heavy by the moment. Even her large chest within that dress, was heaving with each exhale.
Finally Twilight's personal guard, led Celestia to the princesses chamber, before excusing themselves. With a firm and domineering knock, the ruling princess would wait a few moments before letting herself in, quickly giving a gentle bow.
"Hello, Twilight? Pardon my sudden visit, but... I've been needing to come see you. How have you been?"
Of course prior to all this, Twilight had heard about the visit from her teacher. As usual they would agree to meet up a few times per month to enjoy each others company, whether it was garden games or simply tea, cakes and conversation. Today was just another one of those days and finally, Celestia had arrived and it was time to begin the festivities planned for throughout the day.
The moment the beautiful princess stepped through the doorway, the purple maned teen would turn her head and smile toward her gorgeous teacher.
"Princess Celestia! It's so good to see you, please come in, come in!"
Twilight waved her hand toward the woman, allowing Celestia to close the door behind her and enter further into the large room. It was very fancy, typical of a princess. Large, fancy furniture, bookshelves, alchemy equipment and everything a girl could ever need in her bedroom chambers. Now Twilight replied, answering her question.
"I've been fine, Princess Celestia... how about you? How was your journey? Pleasant, I hope."
Celestia gracefully accepted her friend's welcome, smiling as she ventures further into the room. She'd sheepishly fold her dress under her as she takes a seat in one of the lush, expensive chairs in the room, sitting in a very ladylike posture. When she sat however, her legs setting down almost seemed to have a bit more force behind them.
"I apologize for making my way straight to your private chamber when I got here, Twilight. I... didn't mean to drop in while you were still changing, afterall. Still, I thought it might be best to bring up a pressing matter with you in private."
Of course Princess Celestia couldn't help but look her longtime student and friend over. Her dark complexion and figure were certainly something to look at. Especially for someone like Twilight, whom was spent locked up with her books most of the day.
Twilight smiled toward her mentor and nodded. "Not a problem, Princess. Just get comfortable and i'll finish, I don't mind with you here. It's not like it'll be the first time, you'll see me change regardless."
With that being said, Twilight continued stripping from her bedtime clothes. Slipping those nightwear garments from her body, now revealing her naked lower half to her close friend and teacher. That curved back facing Celestia and that delicious, dark backside staring that gorgeous porcelain girl in the face.
"Hmmm..." Twilight hummed as she changed, already removing her top and casting it to the ground like the careless princess she was. Revealing her soft, plush body as it was completely naked. Even now Twilight leaned forward to pick up a few garments she'd placed on the ground, such as panties and socks. "Eh, sorry Princess... what did you say? You know you can tell me anything, right?"
It was now that Celestia's breathe suddenly caught, as Twilight went about stripping down right in front of her. That third leg throbbed ceaselessly underneath her extravagant dress. She came here to ask her student for some help, and she wanted to do it right.
"Well, Twilight, its... hard to talk about. Perhaps its best if I show you. Do come here, dear, and remain in the nude. Let me inspect your backside."
Celestia smiled at her student, her face warm and red. Her hand was outstretched, motioning for Twilight to come near her. "Don't worry my darling, I'm not going to bite."
Twilight was a little confused about that statement that Celestia had suggested she do, but naturally she'd stand and turn, looking toward the woman. "Uh... sure? I guess if you want me to come over... why, did you find something?" Twilight merely asked, making her way over toward Celestia and when she'd reach the girls proximity, she'd turn around and place that ample bottom over the girls lap - merely hovering it there for the moment and not taking a seat.
"What do you see?" Twilight asked, waiting patiently for her teacher to answer. Despite having no clue what was about to happen or rather what she had in store for her at this moment.
The fat breeding stick of Celestia's strained against the confinement of the garter holding it down against her leg. Getting to see Twilight's impressive rear right above her lap, greatly excited the Canterlot princess. She bit her lower lip in anticipation and arousal. It was getting harder and harder to resist, but she was well past that point right now.
"O-okay, Twilight, I'm going to do something and I want you to stay like this, alright? No moving even if it feels weird..."
With that said, Celestia tenderly grabbed the folds of Twilight's plush butt cheeks in each hand, spreading the girl and putting her friend's anus into plain view. A few of her fingers gingerly poked at the puffy donut hole, eyeing it with great interest.
"I know you're a chaste girl, but I wanted to know... have you ever pleasured yourself with only your rear hole, dear?"
Naturally hearing those words, sent Twilight into an instant shade of crimson. It was an embarrassing set of questions and the purple haired beauty wasn't sure what to say. Nervously, she did reply but only just.
"I um... I don't know why you're asking... but yeah... I suppose I have sometimes. With my fingers..." The girl looked back only slightly, but faced forward again. Not wanting to show the fellow princess her embarrassed maiden features. A hard swallow followed, as her backside was spread and she could feel those hands and fingers wandering and exploring her darkest star, of course this made Twilight a little weary but she'd grump lightly.
"O-okay... I promise I won't move... I don't know what you're going to do, but... um... I trust you teacher."
Celestia's hand only began holding onto the dark girl's cheeks all the firmer. The desperate princess moved one of her hands down between her own legs, trying to swiftly hike up her dress.
"T-Twilight...I have something to show you."
The mentor was nervous, but she was far enough now that she wanted to get to the root of the matter quickly. Her hand finally found the garter belt, and she worked it off forcefully, greedily working her girl cock out from her soft thigh. She found the break in her dress, and allowed the angry, swollen member to bounce up and erect freely. The princess managed to finally nestle the head of that bulbous white cock, right on the small of Twilight's back, part of the shaft barely touching the plush cheeks of the student princess.
"I know I said not to move, but maybe you should get on all fours?" Celestia suggested.
Of course the dark skinned princess, found Celestia's requests more and more strange. Now she knew something was up, but she was still hesitant. "I um... okay... I'm not entirely sure about this, but... as I said... I do trust you." Twilight confirmed again, for a second time. Even as she barely felt the breezing touch against her plush backside, she didn't pass any remarks upon it.
In fact she thought it was maybe Celestia's wrist or hand. Something else, besides the head of that fat and angry girl prick. Moments later the purple maned girl leaned forward and slowly lowered herself down and onto her fours, sighing deeply as the weight of her body came now to rest upon her knees and palms. "Princess Celestia, is this okay?" The girl asked, waiting for a reply.
Princess Celestia stared starry-eyed at Twilight, the dark-skinned girl's twerking, bouncing cheeks on spread display. Of course, the girl's puffy starfish, the pucker even more swollen and inviting than Celestia could have hoped for.
"Twilight, we're best friends, aren't we? Teacher and student, and I feel I could count on you if a very private problem cropped up? Could I not?"
Celestia swiftly rose from her seat, her fat dick meat still bobbing freely in the air. She leaned down a bit as her hands found Twilight's young, wide hips and backside.
"For example, say, if I woke up with an angry, insatiable girl cock that I needed to constantly make cum, I could count on you to help me... by letting me use your sphincter as a dick milker, yes?"
The veiny she-dick throbbed powerfully, the head pulsing against Twilight's tight little crack. It dribbled clear pre-ejaculate slime into the crevice, as if wanting to lube up its bountiful future conquest.
The princess was still a bit unsure of the entire situation. The fact that her best friend, and teacher, Princess Celestia was now stood behind her, hands on her hips and massaging her soft ass-flesh was making her quiver. But also causing some worry. When Twilight heard her out, listening to those words and then realizing just what might actually be the case, and what is now happening.
The purple haired teen shook her head. "W-Wait! I'm not sure Celestia... I mean... if you're doing what I think you're doing... then... I... I never did stuff like this before... maybe we should reconsider?" The dark-skinned princess would protest, obviously nervous and weary of what might happen should Celestia continue.
At this moment, Twilight felt that girl cock against her asshole and that slimy, dribbling pre-cum staining her darkened shit hole. Making her quiver and tingle to the very touch, it was a pleasant feel but at the same time - Twilight was an anal virgin and thus she waited to see what Celestia would say.
"Believe me Twilight, I tried to think of something else. I considered fucking my servants, but I can't have word of this getting around, and out of the castle. Plus, I thought it might end up better if I relieve myself with one hol-I mean, person."
The forceful teacher moved her hips forward the smallest bit, gripping Twilight's backside. Her lubricating cock head pressed insistently against her students darling anus, but came as close to penetration as possible, without actually penetrating her.
"Besides, you have the loveliest bottom in the four kingdoms. I bet anal feels amazing for you, and we can keep you a pure virgin at the same time! Now, relax your hole and lean back into it for me, okay my dear student?"
Celestia kept tapping away at the backdoor, leaving the final push up to her darling and prized student.
Gentle gasps escaped her lips, feeling that cock head push up against her winking ring. The more pressure that Celestia applied, the more desperate the gasps of Twilight sounded. Of course the student whimpered and felt shivers spread throughout her entire form. When her teacher complimented her upon her pretty backside, a deeper shade of red spread across her cheeks and she'd mumble slightly. "Mmn..."
It wasn't certain if Twilight agreed that way, but she felt like she was a mere toy for her mentor right now. With constant throbs and pokes of that thick she-dick the girl would grunt lightly and nod. "F-Fine... i'll help you out, seeing as you are my teacher... but i'm still... not sure about this..." Twilight spoke.
Now she'd begin leaning back against that defiant cock, feeling the head poke and begin combining into the flesh of her tight anus. "U-Uuuah... oh... oh goodness..." The naughty princess groaned, leaning further back into it and soon feeling the entire head pop past her natural tightness; which in turn caused a sharp cry of pleasure to escape from Twilight's lips.
"OOAH!"
That was the result of feeling such a heavy, fat she-dick push right into her tightest of pleasurable cavities. Princess Celestia even tensed up the moment she felt those walls clench around her thickened shaft. That anal cave gripped her tightly, not wanting to release it.
"Nnnnnnrf... Twilight... you're squeezing me this... much already? I always knew you were special!"
The mentor once more, complimenting the student. Despite the fact that right now, both of them were engaging in a sexual encounter. Much to Twilight's surprise, she did not see her day ending like this. But of course the cute teenager couldn't do much against her teachers advances.
"Yes... yes... that's perfect... I won't last long like this, Twilight." Cried Celestia with a sexual coo in her voice.
"Ugh! Princess C-Celestia... I... I don't think I can do this... it's really... too much!" Exclaimed Twilight.
"Don't worry my darling student! Yo-You can endure! I know you've endured much worse!"
It seemed Celestia was pretty certain on those words. The princess was positive that Twilight could help her out, though with the amount of time she had spent being pent up on the way here. It wasn't going to take much.
"Nnnnnarrggh...!" Celestia groaned deeply, those slender and long fingers; clenching that soft and plush backside of Twilight. Squeezing her with deep desire, pushing her hips forward and creating a wet clap with both their flesh kissed. Hips against ass. That's how Celestia liked it. Regardless of the fact, that she woke up like this. Pesky Luna.
"Uuoooaoagh...!" Twilight moaned.
These moans only helped to spur Celestia on, her darling student in front of her and being the perfect assistant. What more could a mentor ask for? With another loud, lewd slap. Celestia continued her anal assault upon Twilight, starting to pick up the pace as that thunderstick of a girl-cock continued to pierce into the winking depths of that nerdy princesses asshole.
"Uh! Yes, Twilight... I can feel you squeezing me... everytime I... ugh!" Celestia groaned heavily, as she thrust into that squeezing fuckhole once more.
"Aaaaaaaagh! Princess... you're throbbing inside me!"
"If... If this keeps up... I might just... get you pregnant through your asshole... Twilight!"
"D-Don't say such... things... Princess... please!"
Hot and horny moans, gasps and pants filled the room. As well as the loud clapping of flesh, as both smacked off one another. Both princesses on a pleasurable high. Of course Twilight remained upon her fours, rocking back and forth in response to Celestia's thrusting from behind. Sweet groans escaping her lips, like sweet-sweet honey.
Her chest bouncing and jiggling also. Twilight closed her eyes, panting and hissing through clenched teeth, whimpering as she could feel her pussy swamping with juices. While she wasn't able to touch herself, because of the amount of pressure Celestia was placing on her; she was getting ample enough pleasure through that fat cock in her ass. Surely it would only be a matter of time.
"Princess... I'm really close... ugh... I'm so wet...!"
"You naughty girl... I said I wasn't even going to touch your lady-hood... and yet... aaaah... it seems my sword is doing all the work regardless!"
Celestia chewed down upon her lower lip, humping into that tight asshole with quick thrusts. Smack-smack-smack-smack-smack! Such fluid and lewd noises, as Celestia's hips clashed with Twilight's backside. Ample amounts of liquid, dripping onto the floor between Twilight's legs.
"Hnnnnugh... Twilight... my dearest student... I am... very close..."
The mentor advised her student, but of course Twilight couldn't stop her even if she wanted too. Celestia was putting much more focus into this than before, and it seemed the princess was working herself toward an orgasm that she'd utterly unload into Twilight's poor backside.
"Pr-Princess... please... uuagh... I-I'm... I'm coming!" Twilight quickly announced.
This was unexpected or rather for Celestia, it was. Twilight arched her back, and leaned right back into Celestia's dick. Bottoming out herself, pushing that thick and fat shaft right into her anal-space with full force and allowing the head to poke right up into the depths of her asshole.
"UUUUUAAAAAAAAGH!"
Twilight screamed out nice and loud, surely enough that even the guardsmen at the door would have heard; but they dared not to enter and earn the wrath of Celestia. Twilight squirted directly onto the floor, managing to soak Celestia slightly in the process.
It was the deep insertions caused by Twilight, that pushed Celestia over the edge. The mentoring princess couldn't thrust forward nor pull back, thanks to the anchoring backside of Twilight. That was pushed directly back into those hips, locking Celestia in place while Twilight experienced her cunt-shattering orgasm.
"Yes... yes... I've waited so... so... loooooooooooouuuuuuuuuuuungh!"
Celestia couldn't hold back any longer herself. Thanks to those efforts brought upon by Twilight, the mentoring female found herself experiencing a wildly throbbing prick and taunting balls; which assisted in pumping out a heavy amount of spunk, right into Twilight's accepting anal cavity.
"Uuuuuuuuuargh! Twilight! My darling student! Aaaaaaaargh... this feel too good!"
Those words continued, with a mix of pleasurable groans and grunts. As the princess continued to empty her balls into Twilight's poor asshole. Filling her up like a yogurt pot in a factory, squeezing more juice into her with each climaxing throb of her dick. Until she was finished.
A few minutes had passed and both girls were shaking. Each panting and gasping for breath, while they were completely unable to move. Celestia released her student's hips, giving that backside a small smack as she'd slowly ease back and allow that now softening prick to escape the slickened confines of Twilight's now gaping asshole.
"Aaaaaagh... I feel so... refreshed." Celestia chirped.
"I feel so... full... and... bloated." Twilight replied.
Celestia released a small chuckle from her lips, as she leaned forward with a butt-plug she managed to sneak with her. Pushing it against Twilight's ass, she'd then pop it simply into place.
"AAA-AAAAH!" Twilight moaned. "W-What... was that?" She then asked.
"It's a naughty-liquid stopper my dear... something to stop you oozing all over the floor. We wouldn't want the servants to see something like that, would we?"
"I... I suppose you're right." Twilight added.
"That's my favourite student. I knew you wouldn't let me down. You can remove it when you go to clean yourself up. Now... I must be on my way. This was a wonderful visit Twilight, i'll send word when i'm due to visit you again."
"Y-Yes... of course Princess Celestia... I'm glad I was able to help..."
With a simple wipe down, Celestia was utterly refreshed and quickly fitting her elegant dress back into place. Before she'd cast blankets over Twilight, to hide her from prying servant eyes on her way out.
"Have a wonderful day, Twilight. See you next time, for our next lesson."
