Ayaka Mochizuki, a sadistic case worker at the welfare office, didn't take the job just for work—she's here to sexually dominate and brainwash worthless men into total male masochists. Using her authority, she fully restrains an alcoholic man, threatens him with an electric saw, and fucks him mercilessly. A middle-aged shut-in is subjected to electrified shocks and forced cunnilingus training. A pachinko-addicted man endures BDSM torture and forced pissing humiliation. Finally, these broken men, now obedient sex slaves, engage in a wild, splashing group sex frenzy with her. Obsessed with inferior men's cocks and cum, Ayaka indulges in every depraved pleasure they offer.
