A visit to Sumire Kurokawa's home turns into an entire day of being made to cum by the seductive married woman next door. Her refined beauty and composed demeanor immediately captivate every man who visits, but behind her demure smile is a bossy tease who loves playing with men's self-control. She repeatedly edges her guest, dictates exactly when he is allowed to cum, and takes charge of every orgasm without her neighbor ever finding out.
