Stressed by growing distance from her husband, Airi Mikumo takes a friend’s advice and joins a swimming class. She never intended to cheat, yet gradually begins a sexual relationship with her instructor. The pool is no longer enough, and they finally have sex in her home. With her youthful face and shy smile, Airi gets pounded as her huge tits bounce, her hairless pussy grows wet, and her body trembles through orgasm after orgasm. After such a long sexless marriage, her request to “do it again” makes it clear how much she enjoyed being taken.
