Rina is normally the type of woman who focuses solely on her boyfriend. One day, she visits a male friend's apartment to discuss something about her boyfriend, but unknowingly ends up drinking a powerful aphrodisiac. As the drug takes effect, her body heats up and her rational mind begins to crumble. When he slips his hand into her panties, her uncontrollable desires overwhelm her, driving her to crave a cock. Helplessly aroused, she's toyed with and penetrated by both dildos and a real cock, ultimately receiving a creampie from another man—an intense, shocking betrayal of her boyfriend.
