Casted Desires: A Twisted Academy

<h2>Chapter 1: The Academy of Control</h2>

The halls of U.A. Academy were no longer a bastion of heroism but a labyrinth of dark desires, where the next generation was molded into masters and slaves of a perverse art. The air was thick with the scent of plaster and lust as students learned the intricate craft of full-body casting and the brutal pleasures of domination. At the center of this twisted curriculum was Katsuki Bakugou, once a fiery hero-in-training, now a willing Full Body Plaster Cast Sex Slave, his body a canvas of pain and ecstasy.

Izuku Midoriya, now a sharp-tongued instructor in the art of ownership, strode into the training chamber, his boots echoing on the cold floor. Katsuki, encased in a pristine white cast from neck to toe, lay on a padded table, his broken bones a testament to his dedication. A fuck machine hummed relentlessly, pounding into his uncasted ass, while a spreader bar forced his legs apart, making every movement a humiliating waddle. A cock milker was strapped to his raw, throbbing cock, connected by a tube to a cock gag in his mouth, forcing him to swallow his own cum in a ceaseless cycle of degradation. His moans—raw, guttural sounds of 'Mmmph! Nghh! Hrrrng!'—filled the room, a symphony of tortured pleasure.

'Look at you, Kacchan,' Izuku drawled, his voice dripping with mockery as he adjusted the machine’s speed, making Katsuki shudder. 'A perfect little statue, hard as stone and just as useless. You love this, don’t you? Being broken and fucked raw while you drown in your own mess.'

Katsuki’s eyes burned with a mix of defiance and desire behind the gag, his moans intensifying—'Mmmph! Grrn!'—as the milker squeezed tighter. He couldn’t speak, but his body screamed his answer, his uncasted cock twitching helplessly under the relentless suction.

'Don’t play coy,' Izuku snapped, leaning close, his breath hot against Katsuki’s casted neck. 'You’ve got rules to follow, slave. Twenty of ‘em, etched into your pathetic soul. Break one, and I’ll make sure you regret it.' He pulled out a leather-bound booklet, flipping it open with a smirk. 'Let’s remind you, shall we?'

Izuku snapped the book shut, his grin wicked. 'You’re dripping already, Kacchan. So wet, so fucking pathetic. I bet you’re dying to cum, aren’t you?' He cranked the fuck machine higher, the relentless pounding making Katsuki’s casted body quake, his moans a desperate 'Nghh! Mmmph!' as sweat beaded on his forehead.

'Not yet,' Izuku hissed, his own arousal evident as he watched Katsuki’s uncasted cock pulse under the milker. 'I’m gonna make you beg for it, make that pussy-ass of yours scream. You’re mine to break, and I’m just getting started.'

The room pulsed with tension, Katsuki’s body a battlefield of pain and pleasure, his hard cock trapped, his ass pounded raw. Izuku’s hand hovered over the controls, ready to push him over the edge, the air thick with the promise of an explosive release—but not yet. Not until every rule was tested, every moan earned.
