Due to her daughter and son-in-law's circumstances, Marika has come to live with them. The couple are constantly arguing about work and having children, and their sex life is not going well. The son-in-law relieves his pent-up sexual desire by using Marika's underwear. One night, the son-in-law sneaks into Marika's bedroom. He spreads Marika's legs and places his mouth on her vagina. Marika wakes up, noticing something strange happening in her lower body. "Mother-in-law, I can't hold it in," the son-in-law pleads. Marika, who knows the strained relationship between her daughter and son-in-law, feels sorry for him and accepts him in.
