College woman Motoka Komatsu enters porn to research partner-sharing sex from a woman’s perspective without telling her boyfriend. The intelligent, fair-skinned beauty has never had purely physical sex with a man she does not love, but her curiosity leads her to a hotel for a private sex shoot with a stranger. She openly reacts to every kiss, hug, blowjob, and thrust, then twists her slim waist while riding him and grinding deep. Her hidden kinky side emerges, and after affectionate bath play and another blowjob, she also has a threesome with a different man. While taking another man’s cock, she begs to be told she is loved, creating footage she could never show her boyfriend—and her research is far from over.
