You can't do anything at all...

You can barely see a thing. The fleshy walls of the experiment's colon feel nice and warm, but you know their true purpose. To absorb your nutrients and break your body down into waste. You're not lying down straight, but instead you're body is bent and curved. You assume your ass is the closest to where her lower abdomen is, while your upper body is bent back in toward the center, but you're also laying down on your right side, so you're wrapping around like a snake, somewhat.

The colon and large intestine were large enough to hold you, but they were by no means spacious. Her walls pressed down on your body tightly, giving you close to no room to maneuver. You could wiggle your fingers and shift your legs about a little, but that was about it.

You tried pushing your body back down and out of her anus, but you only felt empty space beneath your toes. She pushed you too far in. You couldn't move your hands enough to push yourself back down, and even if you did reach her sphincter, you highly doubted you'd have the power to push yourself back out.

After a few minutes of trying, it becomes apparent that it's useless. You didn't want to accept it, but you have ****. You have no chance of escape, and you begrudgingly accept your fate.

You feel your body and your prison shake.

"She must be moving..." You thought to yourself. You could feel each footstep as it touched down, trembling throughout her body. You feel pressure for a moment against your ass as you feel the woman's hands pat you gingerly.

"Good girl..." You hear the woman say from outside. "I've never gotten the chance to shit out two women in one day... This is going to be fun... I knew it was right to hold off on that other chick for a while... Let's go see if we can't find a third, hmm?"

You were carried about in her colon for about half an hour as see searched for more prey to stuff up her butt. Thankfully, she didn't find any. At least something went right today...

As your eyes adjusted to the incredibly dim light that shone in through her stretched skin, you noticed something. Your skin was usually pretty pale, but you started to notice it had become fairly tan. You tried wriggling your fingers, and found that they were sticking together a little bit. In addition, moving them had become difficult. You felt sluggish and slow. Digestion was underway.

Your skin became darker and darker until it was the color of dark chocolate. You could barely move your fingers, and your vision was becoming hazy. Your skin wasn't really skin at this point, but a semi-solid layer of mush. Bits of your finger came off when you moved them, and stuck to your thigh.

You felt a "THUMP" and your entire body shook heavily. Your stomach churned as you fell downwards without warning, jiggling in her intestine for a second afterwards. The experiment must have sat down on the floor to rest and finish processing you...

The walls of her intestines contract around you, fusing your arms and legs together. You can barely see, you can't move your tongue or your fingers at all anymore. The mushy brown substance has permeated your muscles, and is rendering your body useless. The contracting of the walls appears to be due to it not being able to subtract nutrients from your skin anymore, so it's pushing down in order to get the last bits from your insides.

You're about 50% shit at this point. Your arms and legs are 100% shit, and really only your vital organs remain. It wouldn't be long now before you met your fate. You thought back to your girlfriend, and all the people who had been counting on you. They had placed their trust in you, and you were only about 20 minutes from being dropped off at the pool. You had failed, and like a failure, you belonged in the sewers... It was only fitting.

"I'm... Sorry... Ryu-" You manage to mutter from your mouth, but you could go no further. Your vision went dark and your mind went blank as your skull was transformed into feces, followed by your brain. The rest of your body soon followed as the contracting of the walls intensified, squeezing you for every last drop of food.

Within 20 minutes, your entire body was a human-shaped turd, simply resting in the intestine of one of Alex's creations.

...

Rosalina the experiment patted the bulge in her belly as it gurgled softly. She slowly got to her feet, and opened the door to her bathroom. She sits her plump ass down on her toilet, and starts to strain herself as she poops you out.

"Unf!" She exclaims, and bites her lip. "You wanted to go down the next floor? Glad I could be of service~!"

Slowly, Rosalina's colon starts to poop you out of her tight sphincter. Your legs are totally smashed together as they emerge, but the rest of your body slowwwwly slides out in near-perfect condition, like a molded chocolate desert.

"Splash!" Your legs hit the water as the turd you've become continues to flow out of her body.

"Ah... Ah... Ah... W-wow! Either you're way bigger than I thought, or I must be losing my touch..."

With a final moan of pleasure, Rosa spreads her cheeks and poops out your head. Like D.va and all the girls before you, the pretty shape of your face and your tidy hair is twisted and smashed beyond recognition, a clay figure who's head had been smashed and twisted into a point. You lay upright pathetically, half submerged in toilet water as Rosalina takes a piece of toilet paper and wipes off her fat ass.

Once she finishes, she drops the paper by your side and admires her work.

"Someday, I'll get a perfect one... I just have to work on keeping my asshole open at the end... Oh well, down you go, dear..."

She pulls the lever, and the water starts to drain from the bowl, taking you along with it. Your body is shaped beyond all recognition as you are plunged into the pipes, your ass being stretched out to three feet long, your breasts breaking off and merging with your neck, and your legs being pulled off entirely as your body is stretched out like a noodle.

You travel down the pitch-black waterway until finally you splash down in a tank. There, you meet your end. You're broken down with all of Rosalina's previous victims, as well as the cum, the piss, and the shit of all the maidens and staff. You wouldn't know it, but D.va, Rosa's previous victim mixes in with your body, turning you into a pile of sludge.

Back upstairs, Rosalina scrubs off the stains you left with a toilet brush. One week from now, she would find another victim, and she too would join you in the septic tank. And so, the cycle of digesting useless failures continued...
