Saya Kirijou visits a relaxing massage parlor in Tokyo for the first time in a while. A familiar therapist offers her a cup of herbal tea, which she drinks completely. Unbeknownst to her, the tea contains a surprising ingredient. As the session progresses, her body grows hotter and her sensitivity increases rapidly. Confused by her unusual physical reactions, she gradually surrenders to the sensations. The therapist coats her entire body with oil, pushing her sensitivity to the brink. Under the aphrodisiac's influence, her consciousness fades as her body becomes increasingly responsive. As the erotic massage continues, oil seeps into her pussy, drool drips from her mouth, and she transforms into a submissive female. Eventually, she reaches for the therapist's briefs and starts devouring his cock. Her transformation is unbelievable—she begins to display an obscenely lewd appearance, losing all sense of self. She begs the man to "fuck me," moaning with pleasure as his bare cock thrusts deep into her uterus. Trapped in an endless cycle of pleasure addiction, she's further drugged and conditioned, receiving creampie after creampie into her swollen, aroused pussy, her eyes rolling back in a classic ahegao expression. This woman is no longer the person she once was.
