The water stretches like an ocean, contained in a single glass, floating in the air with the assistance of purple magic. You struggle to keep above the water, but bigger problems are upon you, as seen by the gigantic maw hovering over the rim of your world.
"The spell will last for the duration of the day, so you don't have to fear going in," Twilight says to you, her voice booming in your ears, as the waters ripple in reverberation. "I'm going to swallow you whole now."
Her giant, plush lips begin to lick at the rim of the glass. You gulp, fearful of when she's going to do the same.
"And remember," she says, tilting the glass up as the currents rush into her awaiting mouth, "thwis is for scwince!"
You've never hated science more in your life, but not quite as much as the darkness that surrounded you as the torrents pull your body past her lips and into her mouth. There's enough liquid in her mouth for you to float, your leg grazing against the monstrous tongue as you attempt to rise above the surface, but this only lets the beast know that you're home.
You look back. The glass, your previous home, pulls away from her lips, which slowly began to close, until you're left entirely in darkness. Your heart races, more so when you feel something slither around your body, and then takes you into its hold.
Its Twilight tongue. She's tasting you.
Her tongue covers your face, filling your vision with small bumps of the spongy surface. It trails down your body, from your chest to your crotch, which you can't help but moan at the potential for having a blowjob from the beast: maybe that would be your reward for complying with this experiment.
You yelp as the tongue begins to sway you. It rubs you along the walls of her mouth, your front getting a soft treatment while your back slides against her pearly teeth, before you are flung to the other side. You feel like candy, your life at her whim, and for whatever reason, you couldn't be more turned on.
Something opens and the water begins to drain. You can breathe properly now, coming to stand on top of the tongue as it became still, setting an eerie chill inside the dank cavern. You feel air rush past you, its warmth washing over your scales, and at the back of the throat, you can see Twilight's pharynx opening up.
She's breathing on you. It feels nice on your cock.
You stand there, eyes closed and enjoying the sensation. The atmosphere of her mouth is one you come to appreciate more the longer you stay, knowing that you were inside the mouth of something far bigger than yourself, going about her day with a creature in her maw. It's like two self-contained worlds, and the thought of that makes your dick erect.
Then the tongue flings itself upward; the sudden movement sends you flying through the mouth. You hit the back of her throat, creating a giggle that rumbles below as involuntary muscles take hold of you.
Down you go, tiny morsel.
Her throat surrounds you on all sides. The muscles clamp on you, sliding you slowly down and covering your scales with thick saliva, but it feels nice enough on you that you don't mind. As you progress, you realize you should be going faster, looking downward to see what the issue is.
The bottomless pit below isn't so much at the moment. The muscles are pressed inward on themselves, obstructing your descent. You quickly realize that Twilight must have a hoof pressed against her mighty throat, keeping you as an adorable little bulge. You imagine the pleasure is as good for you as it is for her.
For science her pony ass.
"If that's the way she's going to play," you say, pressing your claws against the slimy muscles, opening you some space in her esophagus. "Then I'm going to get off as well."
You begin to rock your hips back and forth, feeling your cock collide with the slime, which warms your tip at the touch. You hump upward; you cock gliding up on the surface, as the muscles clamp tighter on your arousal and you because of the sudden activity.
You enjoy the sensation. Your descent starts again, the walls so tight that it presses your cock to your under-belly, and every downward inch is a divine pleasure. You feel yourself coming close, just for the sensation to jack up to eleven.
An outside force presses against your cock, and you know it to be Twilight's hoof, rubbing along her throat to where you were. It's weird, being jerked off through the flesh of her throat, but the idea of it all sends you over the edge as you finish.
Just in time too. The hoof presses down on your head, sliding you down itself. A sphincter opens at your feet, and you fall into a fleshy chamber. You've reached her stomach, glad to see only water and no food. Suddenly, your whole world rumbles and grumbles, as your host begins to move.
The idea of her going about her day with you inside her as your dick rearing for round two.
The walls begin to close in on you, but only from up above. You realize Twilight is rubbing her tummy, at where little old you is standing, and you can't help but find the whole affair kind cute. The constant shifting of the chamber has you stumbling on your feet, but the fact that your host is walking around is driving you madder with pleasure then it should.
You hear a valve open, watching the liquid in the chamber drain around you, and you know where you must go next. You walk open to the valve, letting it suckle on your feet as it begins to eat you whole—the second time today.
You take bliss in how it consumes your body, the muscles rubbing along your body, squeezing you into the tight tunnel. Your cock once again presses against your underbelly as your upper-body disappears past the valve. You wave goodbye to the chamber, hoping to set up a second home there sometime soon.
You enter her bowels. You praise Celestia that they're clean, even more so at this is the tightest space you ever been in. Instead of being claustrophobic, you're just extremely horny. Her stomach rumbles, reverberating all around you.
"Geeze, you move pretty quick." It's Twilight voice; only, you hear it from inside her. The sound is like that of a submarine receiving a transmission from the world above. "I have to admit you feel pretty nice in there. Kinda hot knowing I have a teeny-tiny dragon coursing through my body, my body like a cage to him."
Your world begins to rise as she starts to sit.
"How do you feel about that, Spike?" she asks, and you find her hoof stroking over her midsection, occasionally pressing over you. The fact that a giant hoof is on the other side of this flesh causes you to start humping again. "Trapped inside my body at my own whims, seeing how it works while I remain unaware. You know where you're going, right?"
You nod, despite her never being able to find out.
"You're heading to my butt, my big huge butt, out my asshole and between my cheeks." You hear her moan, her hoof gliding more-so downward. You hear a clopping sound and become very afraid. "I'm going to shit you out. My body has already sucked you for all your worth, and now, it's going to dump you into a toilet."
The clop sounds get louder, her body shivering in pleasure, it having a direct effect on your cock as her walls rub against it. So this is how things are? So be it. You grip your cock in your claw and jerk in rhythm to her distant hoof.
"My little dragon, trapped inside my belly." You hear her moan. "My little dragon, but candy in my jaw." You feel her body begin to quiver. "My little dragon, just shit that's going to come out my ass!"
The walls close in on you as you hear a feminine moan from up above. It's cute and sweet, making your heart complete as you hear a distant waterfall. You cum as well, enjoying the sensation of the walls sucking you for your worth—you didn't mind being shit after-all.
"Whoa," you hear her pant, "who knew having a dragon in you was such a turn on, hey, Spike?" You bang on her walls in response, only to feel them jiggle by your touch. Twilight's giggle rumbles throughout her system. "Well well well! I see you've finally made it to my butt!"
Her body shifts as she stands up, swaying as she walks, and in the distance, you hear a door squeak open. Then the movement ceases as she collides upon a seat. "Guess it's time to get you out my rump. Are you ready, my little dragon?"
The walls clench around you, slowly pushing you out as light shines below your feet. In the distance, you see Twilight's pucker, a vista of white and water down below, but your eyes are drawn to the two things before that.
Twilight's butt cheeks. They clench upon sensing your arrival, the fur adorning them all so fuckable with your cock, as your feet pop at her asshole and dangle in the open air.
"Hope you enjoy being crushed, my little piece of shit!" Your body is pushed out her asshole, before being claimed by her ass on either side, the lavender fur caressing your scales. The globe of her cheeks stretch on forever, and you get the idea to just spend the day between her cheeks as Twilight goes about her business.
But today is not such a day, as the cheeks let you go. You fall, down into the water, creating a splash. Once again, you tread pretty okay, staring up to see those same butt cheeks eclipsing the light of the bathroom. Her pussy looms over you as well, still winking in need, slick with previous satisfaction.
Light blinds you. The lavender rump raise from the seat, Twilight turning back around, and staring into the porcelain.
"Looks like you made it through my experiment," Twilight says, her face monolithic, eyes staring down at you. They narrow. "It also looks like you enjoyed it just as much." You raise a brow, looking down, and seeing your cock again hard.
"Tell me, Spike." You look back up at her giant face. "Do you get off on big ponies eating little you? Of trapping you inside them with no chance for escape except through the way nature intended."
It's hard for you at first, but you nod.
"Good!" A lavender magic surrounds you as it raises you heigh into the air. "Because my pony pussy needs a second rubbing, and you're just the fuel that I need."
The magic ceases. You fall. Upon looking down, you see Twilight's open maw.
She catches you on her tongue, the contact knocking the air from your lungs. You cough, reaching a claw out as her tongue retracts you back into her maw, the giant pair of lips closing afterward, sealing your fate once again.
You gulp.
