Twilight entered the dingy, dirty, graffiti-covered public toilet she had been hearing rumors about for the past week. Whispers around town that seemed to imply a certain white alicorn would frequent a supposed glory hole that possibly existed in the bathroom she had currently entered. Of course, Twilight held her mentor in such high esteem she couldn’t believe Celestia would do something so dirty and naughty. But with the rumors swirling more and more as the week progressed, with at least one pony swearing they knew somepony whose brother’s sister’s uncle’s cousin’s former roommate had visited, it finally piqued her curiosity. If Celestia was really doing what she was rumored to be doing, perhaps, Twilight thought, she could get a glimpse, or even a taste, of Celestia’s royal staff.
Despite the wild variations in stories about what took place at the alleged bathroom, one thing stayed consistent: the time. According to what Twilight had heard, Celestia would show up at 3:00 PM every afternoon. The amount of time spent varied, but that’s not what Twilight cared about. Twilight checked her watch; it was about 15 minutes until 3:00. She had more than enough time to quickly explore the place, confirm if the gloryhole part of the rumors were true and, if they were true, set herself up in anticipation of Celestia’s arrival.
Twilight started with the first stall. She opened the door to inspect it and found… a standard stall, albeit each one covered in various vulgar graffiti. The second and third stalls had a similar appearance. It wasn’t until she got to the last two stalls at the back of the public restroom that she saw it: a hole cut out at about the right height for somepony to shove a cock through. The rumors were true, then. So she entered the next to last stall and began to read the graffiti. She was trying to determine which side she was supposed to wait on.
The next to last stall had a crude drawing of Luna and her cock, with a scrawling beside it declaring ‘Our cock is not that small!’, a statement stating that ‘Unicorns suck the best’, and an implication that Cadance frequented the stall on Saturdays. This was obviously the side that Celestia would be in. That meant the last stall was the one she needed to wait in. So she exited the next to last stall, let the door swing closed, then opened the door to the final stall on the end.
It was just as dirty and graffitied as the other stalls. Only this side had a very large and prominent scrawling right above the hole in the stall wall: ‘FEEDING HOLE’. That was all she needed to confirm the very last stall was the one she needed. So, slightly nervous, she sat down on the toilet and glanced at her watch: It was nearly 3:00 PM.
Twilight waited somewhat impatiently as she stared at her watch. She watched as each second agonizingly ticked by. After what felt like almost an eternity, her watch finally read precisely 3:00 PM. And at exactly the same time, the door to the restroom opened up. There was a brief flash of sunlight from the outside world that lit up the place before the lighting returned to the dingy and dull tone coming from the fluorescent lights above.
Seconds passed. Or maybe minutes. Twilight wasn’t sure. Her heart pounded in her chest as she listened… listened as hooves clacked on the tile floor. At first, she thought they would stop at the first stall, but the sound got louder and more pronounced. They passed the second and third stalls until the hoofsteps stopped at the next to last stall. Seconds passed before Twilight heard the door of the stall next to her open, slam closed, then the sound of the lock sliding into place.
There was one other thing the rumors had mentioned that were similar in all the stories. She was to wait long enough for Celestia to settle in before knocking to let her know there was a customer. There were more rumors about the things that happened to ponies who didn’t follow this rule, none of which Twilight wanted to happen to her. So Twilight waited a couple of minutes before reaching up and knocking against the stall wall next to the gloryhole twice.
At first, nothing happened and Twilight was scared the pony in the next stall over wasn’t Celestia at all. Thoughts of who it could be or if she was actually interrupting a pony relieving themselves raced through her mind until, once she heard the pony in the stall next to her moving about, tossed any such thoughts to the back of her mind. She listened as the pony next door got into place, hooves thunking lightly against the top of the divider. A distinct musky smell wafted in the air and the pink tip of something slid out of the hole in the wall. Twilight’s jaw dropped.
She stared in awe at the sheer size of the pink shaft pushed through. Not only did it have a length rivaling that of Troubleshoes (rumored to have the longest dick in all of Equestria), but also the girth of the thing barely fit in the hole. Enough so that if it became even the slightest bit plumper it would crack the hole and maybe even the stall divider! Making one last check to make sure the rumors were true, Twilight gave a quick glance below the stall divider. She saw exactly what she had hoped to see: Celestia’s royal regalia adorning the hooves. Finally satisfied that it was indeed Celestia and the rumors were true, Twilight began the task at hoof and gave an inquisitive lick to the throbbing shaft.
The taste was more exquisite than Twilight had ever imagined. It was a mix of salty, tangy, musky cockflesh mixed and the lingering scents of the various products Celestia used to keep herself clean. It tasted so incredible, in fact, that Twilight knew she needed to taste the entire length. She dragged her tongue lovingly and almost teasingly over the entire girth of cock in front of her, savoring the flavors she dreamt of tasting dancing on her tongue. And as she lapped up the splendid flavor, the cock grew larger until it strained the hole in the divider.
“My, my, such an eager pony today,” Celestia moaned out loud. The sound of her mentor actually letting out a pleased moan caught Twilight slightly off guard... Enough so that she stopped licking. “But sinking my dick down a tight throat is not on the menu today. Please, turn around.”
Twilight blushed profusely to the point she was the same color as the ripest tomato in the world and her heart skipped a beat. Had she actually heard what she thought she just heard? Getting an eyeful and mouthful of her mentor’s cock was one thing, but to be asked to present herself and be rutted? And even with her meticulous day to day planning, the one thing she neglected to bring was a condom. Which meant what Celestia asked of her... she could end up carrying Celestia’s foal! Excited at the very idea she turned around, hiked up her tail, and began rubbing her warm slit on the throbbing cocktip in anticipation.
“While I appreciate your enthusiasm, I’m afraid you've misjudged me. I have no intention of rutting you either,” replied Celestia through another moan. She allowed Twilight to rub her slit on the throbbing tip of her cock just long enough for her pre to start dripping onto the tile floor below. She was completely ready.
“Wait, what? You’re not going to rut me?” asked Twilight aloud, her tone of disappointment unmistakable. Realizing her mistake, however, she clapped a hoof over her mouth to silence herself. It was too late, though; she had just given herself away.
“Oh?” came Celestia’s questioning statement, though it was obvious she recognized her partner’s voice. “How surprising that my faithful student would seek out my glory hole.” There was a slight pause before Celestia let out a small chuckle. “Though with all the whispers around town, it’s not THAT surprising.” Celestia’s voice got low, more serious, and dripping with sensuality. “What IS surprising is you chose today of all days to seek me out. I wasn’t even aware you were into that...”
“What… what do you mean? Into what?” asked Twilight, completely confused. What was special about today? “I just wanted to taste your cock!”
“There’s nothing I can do,” replied Celestia. “Today is not a day for cock tasting or rutting. And since you’ve entered the stall that means you’ve given consent.”
She lit up her horn and used her golden aura to took hold of Twilight’s back legs. Twilight felt herself dragged backward with the magic, her hooves prodding lightly at the cockslit. Still confused about what was going on, Twilight hesitated to do anything. That allowed Celestia to slide those back hooves right inside the slit. No sooner had those hooves slipped into the warm embrace inside that cock, Twilight felt Celestia’s cock swallow hard around her, sinking half of herself inside her mentor’s tight flesh.
“Wh-whoa, hold on! What are you doing!?” demanded Twilight while half stuck inside the cock. “The rumors I heard talked of tastings and ruttings, not… this!” She felt a small ripple around her as the cock swallowed gently around her, massaging her and trying to keep her calm. “I wasn’t aware this was even still in practice!”
The only response Twilight got at first was a lewd moan from Celestia when the cock swallowed hard around Twilight and pulled here even deeper. She was utterly trapped in the tight tube of flesh with only her forelegs and head sticking out. In a brief pause of her feeding, Celestia finally found her words.
“Mmmm, indeed, there are rumors about tastings and ruttings,” replied Celestia. “But why do you think there were no whisperings about ponies disappearing down my cock? I’m sure you can figure out the reason why, my most faithful and clever pupil.”
Twilight racked her brain to figure out why, though the musk of the flesh around her made thinking a little difficult. Why hadn’t anypony mentioned anything about Celestia cock voring ponies at her glory hole? The other ponies would give her a blow or get a good rutting, then leave, albeit with a much bigger belly than when they started. But why wouldn’t the ponies leave after Celestia… unless… Twilight’s eyes shrank to pinpricks when she understood.
“You… you didn’t!” Twilight exclaimed as panic rose through her body. She began to squirm and attempt to get herself free of the cock. “How many!?” she demanded. “What did you do when you were finished with them!?”
“So far?” replied Celestia, “Only four. As for what I did with them afterward…” Celestia paused, her cock throbbing as she remembered the fates of her other prey. “Well, one brought a condom and asked that she be kept as a trophy back at my castle. A second requested I knock up a mare with the spunk he became. I’m sure he had expected somepony rich or famous but I figured Berry Punch could be a good mother for him.”
“And… the other two?” asked Twilight with a gulp.
“The third I drank and the fourth I flushed. And now,” she paused again to give a thrust and a small swallow with her cock. The swallow was just enough for Twilight to feel but not strong enough actually pull her deeper inside. “You’ll make number five.”
Twilight’s panic and the full realization of the situation finally overwhelmed her, so she began to fight back hard. Despite the awkward angle left by how much of her front hooves were still free, she managed to leverage herself enough to feel herself slide a few inches free.
“Yes!”
Twilight’s attempt at escape only turned Celestia on even more. “Mmmm, no, no escaping…” moaned out Celestia as her predatory instincts spiked. “Besides…” Celestia paused while licking her lips. “Struggling will only make it worse.” As if to punctuate her statement, Celestia gave a hard thrust, a thrust that ended up breaking the stall wall, and a powerful swallow. The progress Twilight had made, what little it had been, was quickly reversed as well as getting pulled deeper than she had been before. “Horseapples… every time I do this I have to fix the stall wall…” complained Celestia through her moans. “But it’s always worth it!”
But Celestia’s advice fell on deaf ears. Twilight’s mind, ripe with panic, wouldn’t allow her to think clearly. Instead, she could only act on her own instincts, which meant pushing, wiggling, and squirming in a futile attempt to pull herself free from the cock. Unfortunately for her, though, each wiggle and squirm just brought Celestia more pleasure. And the more pleasure she felt meant stronger swallows. And stronger swallows meant Twilight was getting squeezed harder than needed and pulled in even faster.
Twilight’s fighting continued until her head was left out the cock tip and the warmth slowly crept up the back. At that point, her fighting stopped completely as she was forced to stare at the far wall. Her last glimpse of freedom before she slipped fully into the darkness of the cock.
The inside of the cock was wet, warm, and slightly calming, not that it calmed Twilight any. Her mentor was still trying to fully swallow her down! And what she needed was one small chance to try and escape. As she felt herself sinking deeper into the warm embrace of the cock, a thought cut through her panic: The wall was still mostly intact, which meant it would prevent her from sinking all the way inside! She had a chance of escape, no matter how small it was!
Twilight eventually felt her progress inward stop when she felt herself bump against the glory hole in the wall piece stuck on Celestia’s cock. There were a couple of small swallows around her, but it was obvious to both her and Celestia, Twilight wasn’t going anywhere fast. Using the reprieve to her advantage, Twilight slowly attempted to make progress back out the cock that had slurped her up. Unfortunately, each attempt was met with another swallow pushing her back against the too-small hole. And with each attempt, the swallows and tugs became harder and rougher. Twilight felt herself tugged harder against the glory hole with each failed attempt until finally the wood wall cracked and splintered. Celestia was so focused on swallowing her prey she hadn’t realized the barrier was gone. A final, exceedingly powerful swallow forced Twilight almost immediately into Celestia’s pendulous testicles.
Celestia’s testicles were one of the assets she was most proud of. With how large they were, Celestia could easily hold a pony or two inside and arouse no suspicion to who or what was hidden inside. And Twilight was no exception; she made absolutely no bulge. Only Celestia, who could feel Twilight’s movements inside her left testicle, would be aware of what was going on.
And despite there being no outward bulge, Twilight found her new location quite cramped. The walls hugged tightly around her in the wet, humid, musky darkness. Wanting to look around, Twilight attempted to light her horn. But as soon as the smallest bit of magic wrapped around her horn, it seemed to disappear.
“Attempting a spell? Did you not do your research on my anatomy?” asked Celestia with a chuckle. “Anything inside of me cannot use magic unless I allow it,” she explained. “As such, each spell you attempt to use will have the energy siphoned off to my own reserves.” She reached down with a hoof and traced over the testicle housing her favorite student.
“Please! Please let me out!” cried Twilight as she tried to find a comfortable position in her warm, musky prison. “I won’t tell anypony what I learned, I promise!”
“Oh, my favorite student, I would love to,” Celestia responded while massaging her sack. “But by entering the stall, regardless of you being aware of it or not, you agreed to the terms of being there. The only way you’re leaving is as one of my loads” She paused her rubbing to think. “Never imagined you would end up being one of my loads, but I can’t say it isn’t enjoyable.”
As the minutes passed by, Twilight felt her fleshy prison get quite hot. It was so hot that Twilight felt like her whole body was covered in sweat. In fact, she felt like the sweat was just pouring out of her and pooling around her in her tight confines.
“It’s…. It’s so hot in here, I feel like I’m melting!”
What she couldn’t see in the darkness was what she thought was sweat was actually parts of herself getting melted and transformed into Celestia’s next load. And as she was transformed, the cum she was becoming ran down her body and pooled around her, not only soaking into her body but also speeding up the process. As she felt more of the ‘sweat’ dripping off her body, Twilight began to feel the strangest sensation spread over her wings. It was as if she had lost all feeling in her wings.
“That’s because you ARE melting,” came Celestia’s response. “You probably think you feel sweat on your body, don’t you? But it’s not sweat at all! It’s just the parts of you already turned to cum.”
Celestia resumed fondling her sack gently. Not only did she enjoy the light touch to her balls, but it also helped speed along the digestion process.
“Soon it will be all over and you will be-”
Celestia’s words cut off and a smirk grew on her face. As Twilight was transformed into royal spunk, an image of her cutie mark slowly appeared on the ball sack housing her. And the more of her transformed, the clearer that mark became.
“Oh, look at that,” commented Celestia in an amused tone. “Not that you can see it from where you are, of course. I’ll just tell you: Your cutie mark is appearing on my ball sack. You know what that means?”
Twilight attempted to respond, but she was nearing full transformation at that point. Her own burbled attempt at speech mixed in with the glorps and gurgles of the testicle turning her into spunk, effectively keeping her from responding.
“Hmmm, I suppose you’re too far gone now to respond. What it means is, you’re almost all spunk now, not just body, but magic and soul as well. Just a few seconds more and…”
A flash of light illuminated the dingy bathroom, briefly brighter than the dim fluorescent lights. Once the brightness faded away, Celestia could see Twilight’s cutie mark fully clear on her sack. She gave a gentle prod to the mark on her testicles and heard the lewd sloshing sound created by the huge load of royal cum waiting for release.
“There we go~” moaned out Celestia. “You’re just another load for me to waste. It’s too bad… If you would have supplied a condom I’d have taken you as a trophy,” moaned Celestia as she gripped her throbbing cock in her golden aura. At first, she just used the magic to grip and stroke along her length, but that feeling wasn’t quite enough. So slowly she reshaped her magic aura into the shape of a masturbation toy. She brought it up to the tip of her throbbing cock, teasingly rubbed the tight hole against it, then rammed her cock into the magic orifice as hard as she could.
With a single thrust, she hilted herself into the ‘toy’, quite enjoying the fact that magic could stretch easier than most ponies. Slowly she slid the magic toy off her length as the magical nubs lining the inside gripped and rubbed teasingly along her length. Pre dripped from the tip of her cock into the warm magic before she pounded hard into her ‘toy’.
“I’d even…” she huffed out between her pants and moans. “Have considered… restoring you to a pony shape… albeit…” Celestia let out a loud moan at even just the thought of what she could have done. “You’d have been made entirely of my cum.”
With the nubs and ridges inside the magic teasing and pleasing her, Celestia felt a familiar pressure starting to build; Her release was imminent. But she decided she couldn’t just waste this particular load. It was her best student, after all. So she decided at nearly the last moment to find some sort of suitable container to hold her load as a trophy. Which meant calming down so she could walk around.
But instead of dissipating her magic from around her cock, she instead slid the warm magic off. The nubs rubbed just teasingly enough that as soon as the last of the nubs brushed over the sensitive tip of her cock, as well as the cool air from the dingy bathroom washing over it, she couldn’t hold back. Her flare expanded, her balls drew up, and the first rope of cum erupted, all while Celestia let out a loud cry of pleasure.
The first spurt splashed on the side of the far wall. The second hit with enough force to splatter and spread on the wall before dripping to the floor. Each shot grew stronger and heavier. And as each shot grew larger, Twilight’s cutie mark faded more and more.
Seconds turned to minutes and it seemed the flow had no end. What was left of Twilight started to pool on the dirty bathroom floor and, as the puddle grew large enough, began to flow toward the drain in the center of the bathroom.
Celestia’s balls clenched up one final time as the largest of all her cumshots erupted from the tip. Twilight’s cutie mark glowed extremely bright before it disappeared completely.
“Whoops~ Looks like I’ve turned all of you, body, magic and soul, entirely to cum. Enjoy the dirty sewers since it looks like you’re not coming back~”
