Des：The nephew of a ronin student came to the Takakura family again this year to take the entrance exam. However, Rina was saddened by the insensitive remarks of her husband and daughter. After a while, Rina talked to her husband for the first time in a while, but her husband fell asleep again. Rina feels depressed and goes to the bathroom alone. While I was washing her body, I played with her aching body and comforted her. The next day, her nephew, who had gone out for her exam, came back. Rina asks how she was. But her nephew was no good, she said, saying that she couldnt concentrate because of Rina. Apparently, her nephew had seen her masturbate yesterday, and the erection in her lower body wouldnt stop, so she asked Rina to do something about it. Rina is confused by this sudden thing, but she loses to her nephews force and ends up ejecting cloudy liquid into her mouth...
