Kokoro Ayase becomes the target of a twisted big-breast fanatic who finds her through a dating app. He acts like a gentleman over dinner, talks her into visiting his nearby home for tea, then secretly drugs her drink. She awakens restrained in a sterile room as his polite mask gives way to a psychopathic grin. Aphrodisiac oil is rubbed over her entire body, forcing her into arousal while she is humiliated, trained and made to cum repeatedly. The relentless abuse drives her into abnormal excitement until her body burns with pleasure and she loses control amid the gang assault.
