Ai Mukai was noticed by her father-in-law and tried every way to have sex: Ai Mukai had just gotten married and something happened when she was noticed by this father-in-law and tried every way to rape her. He was bored with his wife and wanted to find a new feeling, which was his son's wife. Even though he was only her husband's stepfather, Ai Mukai didn't dare tell her husband and could only endure it silently. I don't know if Ai Mukai likes this feeling, or doesn't want her husband to think about it, so she invites her homosexual brothers to watch together.
