Although he is dissatisfied with his wife who won't let him live in her parents' house, he manages to do his best thanks to his kind mother-in-law. Her mother-in-law, Noriko, was a plump and beautiful woman, and I couldn't help but follow her with my eyes. When her father-in-law told her not to mess with him as a joke, she was even more surprised than usual, thinking he had found out, but she laughed and pretended. At night, her mother-in-law goes to take a bath. I went to the bathroom to sneak a peek at my girlfriend's mother-in-law taking a bath. Then, her stepmother played with her own body and masturbated as if to show it to me. I couldn't resist anymore and opened her door and hugged her mother-in-law. Her resisting mother-in-law saw it all, and when she said she couldn't stand it, she did it only this time.
