Stepmother Incest Compliant Slave Mother

Rin, the mother-in-law, was dissatisfied with her husband who always came home late and didn't pay attention to her, and she immersed herself in masturbation to relieve her loneliness, not knowing that her son was spying on her. Although Rin is a mother to her sons, she is a stepmother to whom they have no blood relation, and it was only a matter of time before her rationality collapsed. When the younger brother saw Rin's lewd appearance for the first time, he couldn't stand it anymore and started to devour Rin's sexy body! Then, Rin's older brother, who witnessed the scene, also tells her, ``Mom's your type! I'm going to expose you to my younger brother!'' and Rin does as he is told.
