A married woman who has been married for three years. Currently living with my husband's father. Her busy husband is often away on business trips, and the frustrated wife masturbates, but her father-in-law can't help but grin at the scene. One day, the courier with whom she was having an affair comes and they have sex, but her father-in-law is once again peeping on her. Then, the father-in-law asks for his wife's body, using the fact that he witnessed her masturbating and cheating on her. Her husband threatens to expose her and she can't refuse and opens her crotch. Furthermore, the plump wife gets fucked at night and is made to cum over and over again by her hated father-in-law.
