After ten days of abstinence, Rena Fukii participates in a wild sex project she had been anticipating. The director, eager to push boundaries, secretly administers a powerful aphrodisiac imported from overseas. As the drug takes effect and her body heats up, Rena willingly accepts a cock offered to her, overwhelmed by pleasure as she receives a heavy load of cum on her tongue, smiling in bliss. Even during breaks, she indulges in masturbation and titty fucks, sinking deeper into intense arousal under the aphrodisiac's potent influence. In the threesome scene, she loses all rationality, stuffing two cocks into her mouth with dual blowjobs, grinding her hips and begging, "Put more cock inside me!" as she reaches climax.
