Twilight Sparkle. Ass Mare

She did it. She mustered up enough courage to talk to her friends about it. One of them at least. Just one. Who she swore to secrecy. Pinkie swore. No slip ups. It was time. She told her. She had to tell one of them at least. She’d need help with the others. She told her everything. From her time as Celestia’s cushion, including the night she spent in Celestia’s colon all the way up to Cadance revealing her own debauched mind.

She wasn’t sure what to expect. Would Pinkie run away, never speak to her again. Would she break her own Pinkie Promise and tell everyone?

“Can I try?” Pinkie’s words caught her off guard. Could she try? Try what? Try having Celestia sit on her? Spending a night in Celestia’s colon? “You know? Sitting on your face?” Twilight could practically feel the smoke billowing out of her ears. Out of all of her friends, Pinkie Pie had the plushest ass in their friend group. It had to be all of the cake and pie she ate. All that sugar had to be wonderful for your figure.

She didn’t even answer. Not that she could. Pinkie question had caught her so off guard, she’d forgotten to sit up straight. Her back was cold. She’d fallen over backwards, right off of the cushion. She was now on the cold floor of the crystal castle. She would have sat up. Really she would have. But Pinkie seemed to take Twilight’s “collapse” as a yes. That perfect pink ass hovered over her head for a moment before it came down on her.

Soft pink plushness surrounded Twilight on all sides. Her muzzle was as deep as it could get inside a pink ponut. She knew where her horn was, she was sure Pinkie knew where her horn was. Neither of them seemed to mind really. Pinkie sat there, still as a statue. Suddenly she started moving. Grinding her rump down on Twilight’s face. A hum reached Twilight’s ears. Was Pinkie thinking about this? Was she actually trying to decide if she liked using Twilight’s face as her personal butt plug and cushion?

Even if this wasn’t going to be a permanent thing, did she really like how this felt. Standing up, she looked at Twilight upside down as her purple princess friend drew in a much-needed breath. “I dunno Twilight. I think I need you deeper if I’m gonna see if I like it or not.” Twilight was about to ask what Pinkie meant when that perfect pink ponut engulfed her horn. And then just kept sinking. Twilight’s eyes went wide as it pressed against her head. She expected Pinkie to stop, adjust her position and try again.

A squelching sound reached Twilight’s ears as she realized she couldn’t see anymore. She really shouldn’t have been surprised. It was Pinkie Pie. One doesn’t question Pinkie Pie or her motives. Twilight’s entire head was inside Pinkie’s colon in moments. Pinkie squirmed and wiggled, testing out how it felt. Twilight was in bliss. Breathless, anal wrapped bliss. At least one of her friends didn’t think she was a freak for liking this sort of thing.

Suddenly she couldn’t feel the floor against her back anymore. Somehow her body was being moved, rigidly, with only her head in Pinkie’s ass. Where was she going? Not being able to see or hear was near agony. The sound of Pinkie’s hooves meeting the castle floor was loud and echoing, but also muffled. It was an odd sensation. Doors opened and Twilight felt them nearly close on her hooves. Pinkie had entered a room other than Twilight’s study.

Moments passed until Twilight felt something cold dripping on her body. She squirmed and wriggled, trying to figure out what it was, but Pinkie’s ponut had her head well and truly trapped. Gravity shifted and she knew she was now on her back, as was Pinkie, and that cold stuff was back, now dripping down her front and being rubbed in by Pinkie’s hooves. It still amazed her how flexible Pinkie could be, especially with somepony’s head encased in her asshole.

Twilight squeaked, the sound muffled by the walls around her, as Pinkie’s hoof found her teats and then her sex. Was she really about to help Twilight orgasm while she was like this. Then it happened. Pinkie started pushing. Both hooves were on Twilight’s sex, and she was pushing. Her shoulders strained for a moment before they slipped inside. After that it was quick. Ponies weren’t built like this; Twilight was absolutely positive about that. The intestines were long and winding, not straight and smooth. Yet within moments Twilight found herself curling up in Pinkie Pie’s stomach.

Twilight found she could look around pretty easily. Lighting her horn revealed Pinkie’s last meal, an entire pie, two whole cakes, and a hayburger. She had to remind herself not to question how Pinkie didn’t walk around like a balloon with legs with how much she ate regularly.

Hours passed and Twilight still hadn’t exited Pinkie’s stomach. She knew it had been a few hours because she had her own internal clock. It had been around lunch time when Pinkie stuffed her friend up her ass. It was sometime around dinner now. Was Pinkie going to eat again? Did she need to with Twilight in her stomach? Those questions and more passed Twilight’s mind, but one stuck. Was Pinkie going to digest her? She’d been in Celestia’s colon before, curled up as tight as she could get. She’d never gone so far as Celestia’s stomach.

“Pinkie! Let me out!” Twilight shouted, hoping her friend would hear. She didn’t know if she could, or should, use magic while inside Pinkie’s stomach. She didn’t want to hurt her. There was also the chance that trying to teleport would simply teleport Pinkie and they’d be in the same situation, just somewhere else.

Her surroundings suddenly shifted. She didn’t know what was happening outside of Pinkie’s stomach, but something was happening. Trying to push her hooves out against Pinkie’s stomach walls, she suddenly felt everything get tighter around her. Pinkie was in something. Was she in danger? Had she wandered into the Everfree and encountered a Cragadile? Or a Buffo? Was Pinkie being eaten by something dangerous? Twilight shook her head sharply. Being eaten in general was supposed to be dangerous.

Yet here she was. Having, essentially willingly, crawled her way into Pinkie Pie’s stomach. She willingly climbed into Celestia’s ass whenever she got the chance now, but this was different. Pinkie thrashed around her, struggling and fighting. Then she was out. Twilight was suddenly in Canterlot. In a bathtub. Blinking, she looked around. It was Luna’s private bath. Turning around she saw her rescuer. Princess Luna, with a belly full of Pinkie.

“Worry not Twilight Sparkle. She will not be harmed. Now, about where to put you for the night.” Twilight blinked and was about to suggest she just go home when Luna’s magic pushed her under the water, under her bulging belly and to her folds. Twilight tried to hold herself back, but Luna was just too strong. Twilight’s muzzle entered first, followed swiftly by the rest of her head. Within moments Twilight’s entire body was curled up in Princess Luna’s womb. “Fear not Twilight. We know you are our sister’s toy. We shall not keep you longer than tonight.”
