My parents went on a trip with Masayuki who was injured in a motorcycle accident, and during that time my brother Kazuo and my brother's wife Nori came to my house and took care of me. However, when Kazuo goes on a business trip and is alone with beautiful Risa, Masayuki who is injured and can not masturbate increases her sexual desire for Risa. In front of such Masayuki, I dry the laundry with no panties and clean the bath in a wet and transparent appearance. And Masayuki's patience has reached the limit of Risa's behavior, which seems to be temptation.
