A showcase of four irresistible friends with benefits: Ayami, a 23-year-old married office worker who secretly meets him during trips from Fukuoka and gets even hornier when she drinks; Kokono, a 21-year-old clothing-store gyaru with thick pubic hair, spectacular squirting, and a possessive streak; Mako, a beautiful 32-year-old divorced tax accountant whose eye contact during blowjobs nearly gets him emotionally hooked; and Asami, a kind, sexy 31-year-old married childcare worker drawn into a secret arrangement connected to her husband. No commitments—just four women he meets whenever both sides want sex.
