Seiko, a 35-year-old married woman, emails the studio because she wants to make porn. Her husband, a former classmate of the same age, works for a major corporation and is always too busy for sex, leaving her to masturbate through the frustration. His suspicious behavior makes her wonder whether he is really working or seeing another woman, so she decides to take revenge with her first porn—and uncensored—appearance. The gentle, composed beauty next door reveals gorgeous breasts and a surprisingly filthy side, cumming instantly with toys and repeatedly on a porn actor's cock.
