[Ah, face on top, squirting below] A married woman is given an aphrodisiac, becoming drenched in sweat, her eyes glazed over lewdly, her tongue lolling out, her legs wide open, her whole body trembling and convulsing, squirting while urinating. She becomes the perverted body of Mizukawa Jun, who has erogenous zones all over her body, in the erotic development salon DVAJ-689.

As a reward for herself, Run, a full-time housewife, went to a massage parlor recommended by her husband. However, the parlor was run by a middle-aged male therapist with a wicked reputation. He used a sticky, provocative massage with an aphrodisiac ointment to induce sweating. Run, stimulated and aroused, said "no" but her body couldn't resist the pleasure and she gradually became aroused. She reached orgasm and became incontinent, experiencing multiple ejaculations. Run, whose erogenous zones had been perverted and her body was being developed, secretly repeated this process many times. Her sexual desire was exposed, and she became addicted to the development of her sensuality, turning into a lewd wife who made obscene moans and sprayed her own fluids.
