Two gorgeous girls, Koi Miyamura and Tsukushi are home alone and having a very intimate conversation. Since one of them is dating the brother of the other one, they realized that things have changed once that started. Instead of fighting about his attention, since it is not possible to compare those relations, girls were smart enough to get to know each other better and benefit from that as much as possible. Soon, they were making love with each other and moaning from pleasure very loud, hoping that no one will come home to see them in action, especially because they did not want to stop, until they both experience an intense orgasm. It did not take long for it to happen.
