Trapped in the Cat's Crack, Part 2 (Shortstack, Butt Entrapment, 2nd Person)

“What do nyou mean nyou fell into my butt, nya? Who does that, lmao?!”

Your new world shakes as Nyanko laughs, making the engorged cheeks of her already enormous derrière shake like a pair of puddings. You, caught between them, find yourself bounced from one side to the side, slapped back and forth till you can barely think. “St-stop doing that!”

Finally, Nyanko stops laughing. “Well, I guess I should try to get nyou out of there, shouldn’t I, nya?” 

You swallow. “Y-yeah.” Actually, you’d prefer to stay in here a little longer–it’s so cozy and warm–but you can’t tell Nyanko that, can you? What are you supposed to say? Oh please, Nyanko, please let me stay in your ass a little longer. It’s so snug in here. Ridiculous. 

Hands around your ankles. They tighten and start to tug. You brace yourself to return to the cold, harsh air of reality–it’s a little like being born, even if you’re coming out of the wrong part of the woman. But just as suddenly as the tugging started, it stops. 

“Wait a second,” says Nyanko, and the tone of her voice makes you shiver a little–that’s the tone she reserves for when she’s plotting something. What’s she planning? What’s she planning?! 

Nyanko giggles, making her butt bounce and slapping you from side to side a little more. “If nyou’re trapped in there, that means nyou can’t stop me from doing anything, nya. Hehehehe. Maybe I’ll leave nyou in there a little longer.” 

You open your mouth to respond and abruptly slam it shut, swallowing. It’s true, of course. If you’re stuck in Nyanko’s butt, you can’t stop her from doing anything. She’s free to do whatever she wants. 

On the other hand, isn’t that perfect for you? You want to stay in here, don’t you? If she thinks she’s getting one over on you by leaving you trapped in here, well… You have no reason to disabuse her of that notion. 

On the other other hand… Are you sure it’s safe to let Nyanko do whatever she wants? She isn’t exactly the sma– Her intelligence is less than– She’s… To be honest, she’s a moron. 

And you’re trapped in her butt, forced to go along with whatever stupid idea pops into her head. Are you sure you’re willing to go along with that? 

You bite your lip. Maybe… Maybe you’ll hold your tongue for now. After all, you never know. Maybe she won’t be as bad as you’re expecting.

Your new world shakes, swinging violently up and down as Nyanko rushes for the door. “What should I do? What should I do?!” she cries, gleeful as a child without a parent to stop them electrocuting themselves. “Ooo, ooo, I know! I can finally play in the traffic!” 

You squeak. O-o-on the other other other hand…! 

Before you know it, Nyanko is outside on the street, bouncing up and down in excitement. Even over the clapping of her cheeks, you hear the roar of the passing automobiles. She isn’t serious, is she? You thought you’d weened her off this obsession! 

“Hmm…” Nyanko stops bouncing, and you practically feel her frown. “On the other hand, it does look pretty dangy-rous, nya. And nyou’re kinda weighing me down back there, Senpai. I don’t wanna get hit by a car ‘cos my butt’s so fat I can’t jump outta da way, nya. Hmmmm…” 

You can’t fault that logic, especially when you’re in the danger zone. 

Nyanko ambles away from the road, making her butt jiggle a little more with every step. “What can I do?” she asks herself, sounding a little like every young adult with their first taste of freedom. And like many young adults, she soon gives up: 

Her cheeks part, spilling light into your dank new home. “Hey, Senpai,” she says. “What do nyou think I should do, nya?” 

You take a second to think about this. “Er…” 

“And don’t say ‘let me out’, because I’m nyot gonna, nya!” Giggling, Nyanko gives you a poke. “Nyou’re stuck in there till I say nyou can come out, Senpai. Sorry.” She sticks out her tongue. 

You spend the next several seconds writhing in suppressed fury. You don’t want to get out anyway. You’re quite comfortable in here. “Fine,” you say, trying to sound bitter about it. “Why don’t you go for a nice jog through the park? Maybe all the exercise will make that fat ass of yours a little smaller.” 

Nyanko grabs her cheeks with a squeak, sounding horrified. “My butt’s nyot that big, is it, nya?” 

You decide not to dignify that with an answer.

Despite taking offense, Nyanko accepts your suggestion. Crossing the busy road (via an actual crossing, mercifully), she heads in the direction of the nearby park, with you bouncing around in her buttcheeks with every step. It’s heaven, if a little disorientating. 

As she approaches the park proper, she picks up speed, breaking first into a jog and then, finding that too boring, into a proper sprint. You can only squeal, as much in enjoyment as terror, as you found yourself swung up and down battered around, bouncing from one wall of flesh to another, battered, yet comfortably, as if you’re jumping on a waterbed. 

Finally, Nyanko comes to an abrupt stop. Struggling to recover, you manage to find enough strength of self to ask her what’s going on.

“There’s a thing full of things, nya?” 

She has such a way with words. “What…? Can you describe them?” 

“Hmm. There’s one like a pendulum that these kids are swinging in. And there’s this spinny circle that they’re riding on. And a horse on a spring. And this plank of wood on a pivot that goes up and down and up down and–” 

“Oh,” you replied, “it’s a playground. That plank of wood is called a ‘see-saw’. 

“Ooo, ooo, I wanna try the seesaw, nya!” 

She rushes off, knocking you back into senselessness. You can only lie there in her ass, shivering in expectation.
