Locked in steel chastity and stripped of control, the gimp has no choice but to surrender to his Muscle step-Mommy. Nurse Lee Keyrouz is his keyholder, his punisher, and the only cure for his weakness. Dressed in her tight nurse uniform, her powerful body radiates authority as she straps him down and spreads him open. One by one, she stretches his ass with merciless precision: the chill of glass, the heavy thrust of rubber, the shocking fullness of a fist-shaped plug. But this is only preparation. His chastity cage bites into his skin as Nurse Lee oils her arm, pressing her thick, muscular fist inside his trembling body. Every push, every stretch, every intense movement transforms him from a porn addict into nothing more than step-Mommy’s personal fist toy. His release isn’t between his legs—it’s in the way she breaks his hole and owns him completely.
