A married woman living in Chiba Prefecture appears ordinary, with a serious and modest personality in daily life. However, she still carries a habit from her youth—back in the day, she used to pick up men at Roppongi nightclubs—and even past forty, this desire hasn't faded. On weekends, her longing becomes unbearable, driving her out at night for exhibitionist thrills, seeking thick, intense cum from younger men. Recently, her anal sensitivity, which only blossomed in her forties, has become intensely aroused.
