Falling for men who are always already taken—married or in relationships—only intensifies her desire; the thrill of wanting what belongs to someone else consumes her. Upon learning that her best friend from college is engaged, Kokona Asakura, driven by jealousy and passion, lies in wait for the fiancé. Pretending it's a chance encounter, she invites him out for drinks and seduces him with her F-cup breasts. Though he initially resists out of loyalty, her soft mounds pressed against him, her tongue ravaging his body in deep French kisses, send his cock into relentless arousal. In that state, she mounts him in cowgirl position and forcefully claims him with repeated creampie orgasms. Over and over, she demands his cum, trapping him in a spiral of domination from which there's no escape.
