Meet Sena Kasumi, a lustful college student who's mastered the art of seduction. In 'part4【極上のケツとGカップ】', she finds her match in Nikku, a man who loves women as much as she loves sex. After meeting on the ski slopes, they retreat to a cabin, where Sena, with her G-cup tits and big, round ass, takes the lead. She sucks Nikku's cock with enthusiasm, her cute face bobbing as she deepthroats. The action heats up, with Sena fingering herself, then using a vibrator, before finally taking Nikku's dick. She cums multiple times, her body convulsing, and the scene ends with a spectacular squirting orgasm.
