In a prison outside society, lawless criminals gather in a strictly enforced no-ejaculation zone—any release of semen results in severe punishment. Among them, a sadistic female guard targets inmates whose testicles are on the verge of bursting, dominating them to satisfy her own desires. With a scornful gaze, she inspects and identifies rock-hard, swollen cocks, then mounts them in aggressive cowgirl position to force orgasms. For exceptionally potent inmates capable of multiple consecutive ejaculations, she demands relentless, rapid-fire thrusting. Restraining the men completely, leaving them unable to escape, she forcibly performs creampie sex. Remember this—your dicks are under my control!
