Ririko is frustrated with her husband's long business trip. At that time, my son brought his friend Kousuke. Seeing him frantically peering into her body, Ririko feels mischievous and can't stand it anymore, so she seduces him... No matter how many times I do it, I keep getting fucked by Kousuke's unfailing youthful cock, and before I knew it, it was morning. Since then, as he continues to come every day, she has become exhausted both physically and mentally due to unfaithful copulation.
