Tsubomi was kidnapped and held captive by yakuza as a substitute for her cheating husband. Bound tightly, she is subjected to violent rape, and her sensitivity skyrockets when rubbed with aphrodisiac oil. Though she desperately resists, she cannot overcome the intense pleasure of drug-induced sex, suffering repeated mental breakdowns and involuntary urination. Feeling the deep bite of the ropes into her skin, she undergoes three days of relentless orgasm training, transformed into a tightly clenched sex slave. Amidst a storm of pleasure, she screams, "My pussy is so hot! Fuck me harder, deeper!" dripping with vaginal fluids, drool, and sweat, convulsing violently in a frenzied, mind-blowing climax.
