One day, my husband's colleague Sawaki called me home to drink with my husband. However, her husband never came, and when she was alone with Sawaki, she received an e-mail on her cell phone. From my husband... Sawaki lied and called Rena. Sawaki has been secretly in love with Rena for a long time. Then, as if to impose that forcible affection, Rena is tied up with a rope. Furthermore, Sawaki fixes the toy to Rena who is unable to move and leaves it alone. Rena's heart gradually shakes in the days of forced pleasure with such a husband's colleague.
