Bewitching woman's love, protected forbidden bond

Jun was taken in by his father during a divorce, but after his father passed away, he returned to the house where his younger sisters Natsumi and Ryoko lived. That night, Natsumi and Ryoko have become passionately entangled as usual, talking about how Jun has grown to hate men due to the trauma of his violent father, but Jun seems to be different. In order to find out the truth, Ryoko approaches Jun and fondles her breasts as if admiring her mother's image. As sobs began to leak out of Jun's mouth, Ryoko's hands slipped into Jun's lower body and their tongues intertwined as if they were melting into each other.
