Tsumugi (Tsumugi Akari), 27 years old, in her fourth year of marriage. She used to be active in show business and was becoming popular, but retired to focus on being a housewife after marrying Yuta, a photographer. By chance, she did a nude model shoot where she crossed the line with a young man she met. This sparked an uncontrollable desire in Tsumugi... Facing a cock she hadn't experienced in a while, this housewife lost all reason! "I... I want to suck it..." She can't believe that sex after such a long time feels this good!! This is a forbidden sexual act.
