After planning everything with the husband, a pickup artist approaches his wife Ai and talks her into dinner and drinks while the husband watches from the shadows. Aroused and tipsy, Ai masturbates with a vibrator, then drains the man with skilled oral. Her husband suddenly appears and she freezes in confusion, but the other man keeps thrusting into her mouth in front of him. He then penetrates her bareback. Ai begs her husband not to look, yet when asked whether the man should pull out, she moans that he must not stop. Her excited husband stares at the penetration until the man creampies her; Ai watches the semen run from her pussy and touches it with her fingers, completing their extreme cure for marital boredom.
