In 2XXX, the era of gender equality has ended, and female supremacy has become the new social order. As a result, men are now seen merely as tools for reproduction, and vast numbers of them are imprisoned. Day after day, they are treated as living semen dispensers—penis-shaped toilets for the pleasure of female prison guards. Into this execution chamber steps guard Hibiki, dressed in black boots and a sexy uniform, lining the male prisoners up in a row and smirking as she forces them to masturbate one by one. For those who can't cum quickly enough, she demonstrates with a dildo handjob, bringing them to full erection before subjecting them to various pleasure tortures—handjobs, assjobs, nipple twisting—to extract every drop of semen. The first muscular prisoner to ejaculate is rewarded with a deep-throat blowjob, her swallowing his cock down to the root, then flipping into a 69 position, grinding her dripping pussy against his face as she cums repeatedly, forcing him to taste her thick fluids. Meanwhile, the flaccid weakling who failed to cum is bound upside down and whipped with a riding crop; Hibiki doesn't miss how his screams mix pain with pleasure. Lying the men on the floor, she torments them with mustard and Tabasco handjobs, making them writhe in agony until they explosively shoot their loads. She then forces a penis clamp onto their cocks and subjects them to candle wax torture and relentless handjob torment. Finally, during the group penis-meat-vessel punishment, all prisoners are released from their cells and forced to worship her body—from the tips of her black boots to every inch of her skin. Four erect cocks are brought to full hardness through handjob and blowjob, then she straddles the men lying on the floor, riding them in a vigorous cowgirl position, making their cocks gush with pre-cum. "Move your hips harder and make me feel good!" Hibiki screams, as the men desperately thrust from behind with her in a standing doggy style, or spread open like a lunchbox, each using their favorite position to please her. The high-pitched moans of the female guard echo throughout the prison in this world.
