Rieko-san, a beautiful mother-in-law living in Hakodate, Hokkaido. This time, my beloved wife will be hospitalized for a while, so she will be leaving the house empty. So, she came to Kyoto alone for a while, leaving her husband at her parents' house. So, my life with my mother-in-law and daughter-in-law began in my house!! A life alone with my son-in-law, in contact with a young man, my mother-in-law's thirsty female body regains its moisture!!
