While washing dishes in the house, Furukawa suddenly heard a knock on the door, thinking that her husband came home from work, she eagerly ran out to open the door but no, it was her husband's friend and also her mistress. As soon as he opened the door, the bastard friend who had jumped into a passionate hug and kiss, groping all over his body, he wanted to have sex with her. At first, she didn't agree because she was afraid that if her husband came to see her, something big would happen, but after being reassured by him and thinking about it, she changed her mind and clumsily clumsily with him. Although she knew that this was extremely wrong, perhaps because her husband was physiologically weak or unable to have sex, she had to find another person to satisfy her needs, unfortunately that person was her husband's friend.
