Eventually give up and face the consequences Shrunk in an Amusement Park chapter 16 by Louka31

After several minutes of trying you realize you can't reach the top, "I give up," you finally admit.

"AHA!" she exclaims in glee, "You know what that means...my butt demands a sacrifice!"

You plead with her but she's set on this one. She picks you up and places you on top of her butt, "Undress!" she commands, you're afraid to refuse, so you strip quickly, "Now we can do this the easy way or the hard way, you can either go in of your own free will or i can push you...CHOOSE!!!" at that last word she wiggles her bottom, causing you to lose your footing and almost slip in. Afraid to disobey you choose to go in peacefully, and so you dive in feet first. Her butt is really deep to you and you find yourself sliding in for what feels like forever. It's really clean after her shower and smells nice. Her butt is really soft and you begin to wonder what kind of punishment this is. Eventually, however, you make your way to the bottom, and find yourself at the hole. Suddenly...

As you chill in her butt, thinking about how this isn't so bad you hear her thunderous voice, "What is this vacation? Get to massaging por favor!" so you begin to message her butt hole. You begin first with your hands, then with your right leg, and eventually you decide to try your whole lower half. As soon as you get half way in she clenches shut, trapping you halfway in. "Now I have you right where I want you...MWAHAHAHA," she cackles. You wonder why she didn't just put you there herself but you figure she's still just role playing, "I've ordered some food, and you will stay where you are until I finish!" She quickly slips on a skirt and blouse. Just then you hear a knock on the door. She opens it, takes her mystery food, thanks the delivery boy and closes the door. She then strips, flips on the t.v., lies down on her belly on the bed, and begins to eat. She eats for around an hour (the length of two t.v. shows) then stops.
"Ok, can I come out now?" you plead.
"Not yet sweetie...there's more to come..."
"Fine, whatever but can I at least have something to eat? I'm starving," you reply.
"Ok," she giggles, "you can have some of my leftovers."
She reaches back n gives you a finger-full of some brown glop. It tastes familiar but you can't put your finger on what it is. You begin to feel pressure building beneath you, and her muscles start to hold you tighter in place. "Um...what did you have?" you ask.
"Burritos!" she exclaims in glee "Shouldn't be long now..."
You beg her to let you out before the eruption, but she just laughs at your plight. For some reason a quote from Willy Wonka and the Chocolate Factory comes to mind, when that fat kid gets stuck in the pipe, "Remember when you asked me how a gun works?"
Suddenly she lets rip a tremendous fart that shoots you high into the air! She farts for what sounds like 5 seconds, and you come down lightly on the bed next to her. She's laughing so hard she's starting to tear up, and in her glee she doesn't pay attention to what shes doing and rolls her massive booty on top of you. She's laughing so hard she farts again, setting her into a new giggle-fest. Her farts don't smell too bad, and as she laughs you can feel the vibrations coursing down her body as the waves formed in the fat of her ass massage your body. Because you find yourself between her cheeks and not crushed by them, you're finding yourself enjoying your predicament. Eventually (after a few more impressively huge farts), she calms down and sits up to find out where you went off to. "Baaabyyyy...where'd you gooo..." You respond by furiously trying to move, which gets her attention, "Sorry little guy, guess I got carried away there," she then gets up and plucks you from your fleshy prison, "So what do you wanna do now? I'm sorry for getting carried away, we can do whatever you want."
Hmmmm...
