To sightsee in Tokyo, Mirei decided to stay at her daughter's place. When she talked about her daughter's childhood friend getting married and pregnant, her daughter's face clouded over, and she left the room. According to her son-in-law, their relationship is good, but they don't have sex at night. Mirei was worried but thought it was their business, so she kept it to herself. After taking a bath, she opened her daughter's room and caught her son-in-law masturbating with her underwear. The sudden situation flustered him, and Mirei felt sorry for him, thinking he must be desperate, so she gave him oral sex until he climaxed.
