The daughter-in-law is more interested in her father-in-law's hot penis, which is more lustful than her sexless husband's. The father-in-law comes to stay at the newlyweds' home and gets excited when he sees his daughter-in-law's panties while she does housework. The daughter-in-law is so excited to be seen that she even shows off her underwear to her father-in-law when she takes a bath. He peeks at the daughter-in-law masturbating in frustration at not being able to have sex with her husband in the newlyweds' bedroom, and the daughter-in-law sneaks into her father-in-law's sleeping room and rapes him, saying, "Father-in-law, you have to take responsibility for my husband." The naughty daughter-in-law embraces him tightly and enjoys his hot penis.
