“Sister?” called Celestia, standing outside the door of Luna’s bedchamber. “As long as you will be spending the day awake, would you care to join me in a midday repast? I make no promise as to the presence or absence of pranks, but... what is life without risk, sister dear?”

There was no answer. Wary of potential pranks, she put her ear to the door and faintly detected the sound of rushing water. “The shower!” said Celestia, putting her hoof to her forehead. “I should have pranked the shower! Well, live and learn…”

She pushed the door open cautiously and stepped into the empty bedroom, eyeing the closed bathroom door on the far wall. “Perhaps I could still surprise her somehow… maybe cast a spell on the door? Hmm, but what spell to use…” she trotted thoughtfully across the room, focusing her mind on the question at hand.

In fact, she may have focused too closely on the question, because in doing so she forgot about something she should have been very aware of. The invisible, magical trap she had laid on the floor of Luna’s bedchamber was directly in her path, and she trod upon it unwittingly.

The trap sprung, flinging her back through the door and into the hallway. And that wouldn't have been so bad, if Chrysalis had not happened to be walking by Luna’s bedchamber at just that moment. If Celestia had been launched into an empty hallway, she could have dusted herself off, her embarrassing mistake witnessed by no one. She might even have had time to set another trap for Luna.

But Chrysalis was there, and as the doors to Luna’s bedchamber burst open, her jaw dropped in shock. And her open mouth she as set at just the right angle that Celestia’s horn sailed right down her throat, lodging the sun princess’ head in the changeling queen’s mouth.

Chrysalis staggered back in surprise and confusion, and her throat reflexively pulled Celestia inward, drawing the princess’ head deeper. At this point, Chrysalis regained enough presence of mind to see what was in front of her: the struggling body of Princess Celestia herself.

Chrysalis watched Celestia’s hooves scrabbling on the marble floor, struggling to find purchase. Reflexive muscles pulled the princess deeper, lifting her forehooves off the ground as Chrysalis swallowed her up to her withers. The changeling queen felt a moment’s annoyance at the situation; swallowing Princess Celestia, while a strangely exciting prospect, had not been part of her plan for this visit. She would have to incorporate this into her long-term agenda.

But there was no going back now. The throat muscles of a changeling were rarely used but surprisingly strong, and she could not have freed the princess if she'd tried. Although - the deeper Celestia went, the less she wanted to release her. The bulging in her throat was agonizing, but there was something sensual about being filled in this way.

Chrysalis moaned, stretching her neck to try and loosen up her throat. The thickest part of Celestia’s body was making its way into her mouth, her legs forced back against her chest as her upper thighs were pulled past Chrysalis’ lips. The changeling’s legs quivered, and she lowered herself to her knees, muffled moans escaping her throat as she gulped down Celestia's body inch by inch.

There was a twinge of sensation between her back legs, and Chrysalis felt moisture gathering on her bright green pussy lips. I can't believe this is making me horny, she thought. The thought of swallowing an alicorn never even occurred to me, and yet… Celestia is inside me, powerless to escape, and being pulled deeper… my body is exerting its superiority over hers, enveloping it, absorbing it.

She lowered her back legs to the ground until her wet lips touched the floor. The hallway was all glistening marble, polished and cleaned each morning, and the floor was smooth and - at first - shockingly cold on her exposed marehood.

As she felt Celestia’s folded wings hit the back of her throat, she moved her hips slowly back and forth against the white marble floor, smearing it with her glistening fluids. It wasn't the most effective method of self-pleasure, but she had to do something. The heat in her cunt was rising with every helpless squirm of Celestia’s forelegs, and she would go mad if her pussy wasn't satisfied.

Chrysalis felt her belly start to bulge as Celestia settled in her stomach. Her forelegs had been kicking and thrashing when they were still out in the open, but now she was bound up tight by the walls of Chrysalis’ stomach and she could do nothing but squirm. Chrysalis moaned, a blush rising on her onyx-black cheeks as Celestia’s head and hooves fought uselessly against her.

And then, with her mouth stretched over the back end of Celestia's barrel, Chrysalis tasted something sweet and surprising. Not the lingering flavor of cake frosting, still clinging to the princess' fur - this taste was stronger, muskier, strong and feminine. Chrysalis hadn't given it any thought, but now she realized it was obvious. Of course Celestia's cunt would pass over her tongue as she swallowed the princess’ body.

While she'd never considered swallowing her enemy before, eating her pussy had figured into Chrysalis’ fantasies. She'd pictured a dungeon cell just for Celestia, where she would chain up the princess and take her to new heights of pain and pleasure. The changeling queen had more than once brought herself to climax with such thoughts, and now she realized that her current situation was strikingly similar. Celestia wasn't chained up, but she was helpless and struggling. This was a once-in-a-lifetime opportunity.

And as Chrysalis’ tongue snaked out to part Celestia’s marehood, it was met with another exciting surprise. The sun princess’ cunt was dripping wet, overflowing with juices and faintly clenching, begging to be touched. Celestia was disoriented, desperate to escape - but apparently being swallowed was turning her on. As fearful as she was, her pussy betrayed deeper, more sensual feelings.

Chrysalis did what she could to slow down the swallowing process. Her throat muscles still wanted to pull the princess deeper, but Chrysalis needed to keep her in place - at least until she could make Celestia cum. She sank her nimble tongue deep into the princess’ folds, drinking up her juices and flicking wildly inside her. Chrysalis watched Celestia's back legs kick - not in panic, but in arousal.

Chrysalis flicked the tip of her forked tongue over the sensitive nub of Celestia’s pussy, and her hooves clacked against the marble floor as her back legs twitched violently. Inside the queen’s belly, Celestia's forelegs twitched almost as hard - but they were sealed tight in Chrysalis’ stomach, reducing their movement to spirited squirming that only excited Chrysalis more.

Still rolling her hips against the marble floor, Chrysalis leaked more juices from her pulsing green cunt, producing a growing puddle under her thighs. Humping the floor, by itself, would not have been enough to get her off - but the taste of Celestia’s royal cunt and the writhing fullness in her stomach was getting Chrysalis very close. And Celestia was coming right along with her - the muscles of her pussy were constricting around the changeling’s snakelike tongue, and quick, sharp breaths were rising and falling in her chest

Chrysalis decided to finish Celestia off. She positioned the forked tip of her tongue over Celestia’s clit and flicked it rapidly back and forth, whipping the slick muscle over the sensitive little nub. It was a maneuver she'd used frequently to pleasure female lovers while in disguise; if any of them noticed that their partner had an unusually shaped tongue, they were too busy cumming their brains out to say anything about it.

And Celestia was no different. Her back half seized up, her legs straightening as her pussy clenched, and then her marehood throbbed again with an earth-shattering climax. Chrysalis could feel Celestia’s cries resounding in her belly, shaking her body from within - and that was more than Chrysalis could take. She came, her thrumming cunt spilling more and more pussy juice over the pristine marble floors.

Chrysalis’ conscious mind was submerged in the tidal wave of her climax, and her body resumed the task of swallowing its meal. Celestia, still cumming, slid further down into Chrysalis’ throat, her dripping cunt sliding past Chrysalis’ tongue and giving her one last taste. Her rump, the widest part of her, forced Chrysalis to relax her jaw even further - but the changeling queen barely noticed. She just felt one final convulsion of her cunt as she felt Celestia's back legs slide into her.

Chrysalis rose on unsteady legs as her climax ran its course. The orgasm had left her weak-kneed, and on top of that she was now carrying around a massively bulging belly, a huge writhing lump with the full weight of an alicorn inside it. Chrysalis reached up a forehoof to massage her strained jaw, marveling at what she'd just accomplished. “Unbelievable,” she whispered. “I always knew I'd conquer you, Celestia, but I didn't think it'd be today. And I couldn't have guessed it would feel this good.”

Chrysalis jumped as she heard a voice from within Luna’s bedroom. “Oh sister!” the princess called out, “We were pleasantly surprised to find our shower free of traps… we trust you are not hiding nearby?”

Chrysalis backed away from the door to Luna’s room. She didn't want to risk an encounter; she wasn't sure she could fight effectively in this state, should Luna discover what she'd done. Hastily, she pushed through Celestia’s bedroom door and ran to the balcony, casting an illusion over herself to appear as an unassuming pegasus. She leapt off the edge, barely making it over the railing with her added weight and the low-hanging belly beneath her.

Chrysalis drifted to ground level without attracting any unwanted attention, and trotted towards the edge of the city with a casual air. She noticed suspicious eyes turning in her direction, and nearly panicked - had she not disguised herself properly? She wasn't prone to mistakes…

She looked down at the generic, cream-colored body she'd given herself, and spotted her mistake. She still had a belly down to her knees, softly squirming with the motions of the sun princess. Raising her head, she walked on proudly. Let the ponies stare, let them talk. They'd never guess what she had within her.
