After her colleague is murdered and she is raped, Rumi Kodama vows revenge against the drug cartel. She infiltrates their hideout, but her investigation is exposed and she is captured. Her big tits are groped, she is brutally raped and cum is shot into her mouth, and she is injected with drugs. Her burning body is whipped, tortured with vibrators, candle wax, and electric massagers—alternating pain and pleasure. Choked during rape until she loses consciousness, she climaxes with convulsions. Endlessly trained like a bitch in heat, Rumi eagerly devours cock when it's offered, becoming a submissive slut who takes creampie after creampie in a relentless gangbang, moaning like she's in ecstasy as she's repeatedly filled and destroyed.
