It's been 3 years since we got married. In order to make my wish of having a child come true, my girlfriend's husband is trying to get pregnant, but he only has sex in the morning and is indifferent. She feels lonely, and after her husband goes to work, she fills the void by having creampie sex with her adulterous partner, Mr. Yamamoto. If she had been loved more by her husband, she wouldn't have cheated on him.
