Kana Mochizuki, a Japanese language teacher, possessed a beautiful figure and voluptuous body that made her the center of desire for adolescent male students. The swell of her breasts, her plump hips, and the movement of her lips deeply stirred the boys' emotions. One day, a group of men ambushed her collectively and began recording the assault. Kana erupted in fierce anger, but she was overpowered by their brute strength. From that day forward, her body became an object of training and restraint.
