Brain

You chuckle a little as you inscribe the word “Brain” onto the padded diaper, “This shit can’t possibly be real”

Still, you bite your lip gently as you imagine the potential consequences of what you’ve just done. You’re smart, you shouldn’t be this careless with something like this, but that only excites you more. Not wasting any more time worrying about the consequences, you step into the diaper and pull it up to your hips. “Oh, that’s soft…” you mumble to yourself, squirming a little to full appreciate the padding between your otherwise-naked thighs. “…mmmm…”.

The unexpected pleasantness of the diaper wrapping around your sensitive crotch makes your body tense up slightly, and you let out a faint moan of pleasure. Your new sensations are interrupted, however, by a tickling gurgle you feel from the back of your throat. Your eyes open and you frown, that felt like your stomach churning slightly, but higher, almost up to your…

Another gurgling noise rumbles your skull, and your eyes fly wide open in horror as you realize: your brain, it’s starting to digest itself! “F-fuck!!” You cry out, fumbling in panic with the hem of the diaper, your frantic fingers slipping across the tight edge of the material while your head rumbles loudly. The noise is loud enough to be heard from outside your head, as the precious intelligent meat of your brain starts to scramble right there inside your skull. You gasp and groan, eyes rolling back and hips bucking as your neurons start dissolving, causing mass confusion in your head. Colors pop and swirl together in your decaying vision, and everything crackles with a texture like fuzzy electricity. Grunting like a dumb pig, you can’t help but drool as your motor functions misfire and melt away, and years of memories are burned away by the heat of digestion. You try to cry out for help, unable to remember if you were alone, or who you even are, but all your mushy brain can muster is “C-carrot! Mix -ng-guh- penguiiiin-!!”

Your hips dumbly thrust forwards repeatedly as your body spasms, fucking the padding of the diaper as your reptilian brain panics and bubbles up into a pile of shit inside your skull. Squealing, you flop onto your back, spasming violently and squirting messily into the diaper, your face s mess of drool and snot as your turd of a brain flushed down the back of your throat and starts gurgling out your throbbing ass into the diaper. Your mulched brain piles up in the tight diaper, bulging the fabric with a wet sound as you shit the last of your sentience into the padding, then collapse with a weak whimper.
