SPRD-819 Mom, you're way better than that bitch wife... Chiaki Shinomiya

Weekend. A young office worker named ShinTarou lives with his wife in a certain place within the city. He was hurriedly tidying up the house to welcome his mother-in-law, who would soon arrive. His wife's mother, who lives in the countryside, is coming to visit her daughter and son-in-law, traveling far by train to Tokyo. Hearing the doorbell ring, ShinTarou involuntarily held his breath as he anticipated the voluptuous figure of his visiting mother-in-law, Chiaki Shinomiya, entering the house.
