To support her daughter who is about to give birth, mother-in-law Rina Shigeru went from home to Tokyo to take care of her daughter. During my wife's pregnancy, I had to abstain from sex with my wife, and I was ordered to masturbate during this time and not go out with girls. A few days later, while hiding in the bathroom and masturbating, my mother-in-law discovered that because I was so angry, I pushed my mother-in-law. Maybe she also sympathized with me and also felt like she was going to climax, so she have sex with me until my wife gives birth to a child
