Принадлежащий:Yuis father died after remarrying Horai. Yui and Penglai are stepsons, close in age, mother and daughter-in-law, but they get along like friends and live together. Yui couldnt forget the ecstatic expression of Horai who was tied up before, and she hid her feelings for Horai. One day, the two of them discover that they both feel the same way... and get stuck in a swamp, even though they know they shouldnt. Rich lesbian play methods, including hard spanking, hanging and bondage, and enema to test and confirm each others feelings.
