The highly popular series, volume 4! This time, debuting is Shima-tani Ai, a current OL at a certain top-tier company. She has an ultimate body in terms of looks and style, but she's inexperienced when it comes to sex. Too embarrassed to do it, she can't even make a sound. Director Futamura Hitoshi teaches her "real" sex. Her body cries tears and reaches orgasm from plays she's never experienced before.
