Riri looks even sexier when an old classmate sees her again at a reunion. After the gathering, he invites her for a private drink and learns that she is engaged to their mutual acquaintance Sugiyama but dissatisfied with their sex life. She says no but kisses him back, quickly growing aroused by the thrill of betraying her fiancé. He strips her and sucks her marshmallow-soft tits until she moans with pleasure. In the end, he cums inside her. Riri complains that she told him not to finish inside, yet looks oddly pleased, and he offers to satisfy her again anytime.
