Sakura, who confessed her feelings to her beloved teacher. She never thought it would end up like this... That day, she was tied up and would spend her school life as a perverted teacher's masturbation tool. Sakura, who stays after school and is captured one-on-one with a teacher with ropes, and has a strong dick thrust deep into her pussy in a state where she can't move. She showed a beautifully assimilated erotic expression of painful and pleasant expressions! Wakana Sakura, who had just been allowed to creampie and still challenged a bondage work, is greedy to become erotic. Neck strangulation, intense spanking, strong pistons, all of them are erotic! I don't know if it will appeal to bondage fans, but I was able to meet an erotic bondage work for the first time in a long time. This is also a result of the successful combination of director Niku-son's perversion and Wakana Sakura's strong desire to grow. This is truly a masterpiece.
