The sixth installment of the 15th anniversary project is a godly collaboration with S1's popular exclusive actress, Yume no Aika-chan! My brother's wife, Aika, who is sometimes cold to me. One day, while I was watching an AV, she suddenly barged into my room! And for some reason, we ended up watching it together! That night, she said, "You're responsible for keeping me up all night," and our secret lover relationship began! Is her cold attitude when we're with the family a strategy to avoid being found out by my brother? Or is it just shyness? A completely subjective, forbidden relationship of non-stop sex! Living together in an illicit affair with my brother's wife who can't be honest!
