A 3 night and four -day training for 3 nights and 4 days invited by senior Jun for Shiori, who has just become an esthetician. At a training facility that was far away, it was supposed to be peeled off as an esthetician under the guidance of gentle seniors. However, what I was waiting for was a pure lesbian training aiming for Shiori's G cup milk. "I have to understand both the heart and body of a woman to be a top class." The pure lesbian tech, which does not stop from that day, is hit by the body, and the body of Shiori gradually changes.
