Riri looks even sexier when they meet again at a class reunion. Afterward, an old acquaintance invites her out for another private drink and learns that she is engaged to their mutual friend Sugiyama but dissatisfied with their sex life. She says no yet kisses him back, becoming aroused by the thrill of betraying her fiancé. He strips her, sucks her marshmallow-soft tits, and soon has her moaning with pleasure. In the end, he cums deep inside her. Riri protests that she told him not to, but she looks strangely pleased as he offers to satisfy her again whenever she wants.
