The bad students called Nanako, a beautiful female teacher with beautiful legs, to the classroom after school. Nanako listened to the delinquent leader Miyamoto, who was grinning and saying, "Teacher, I saw it," in a tone that clearly created an uneasy atmosphere. "You can't lie, I asked him later. He said it was really erotic, teacher..." Nanako desperately denied it, but it was true that she was secretly dating a male student. The bad students, not missing Nanako's reaction that she couldn't hide, suddenly started to caress her forcefully, saying, "We can find out how sensitive you are if we check it out." When they played with her nipples, her sensitive body couldn't suppress the twitches and she showed a clear reaction of pleasure. Nanako strongly denied it, saying, "I'm not feeling anything!!" but she couldn't stand the electric massager and Nanako with her legs shaking. With two penises thrust before her, she closes her mouth but eventually sticks them out, and while still holding one in her mouth, she accepts the insertion of the erect cock from behind, bringing her to orgasm again. "You put it in at the end..." Miyamoto urges her, and he pushes his stiff cock into her vaginal opening in the missionary position, thrusting violently into her, ignoring Nanako's Nanako that "I definitely don't feel anything!!" as he pours a huge amount of semen into her uterus...Despite the circumstances that prevent her from succumbing, the unyielding Kokoro of this sensitive female teacher and her slutty, ripe body reveal her true masochistic nature.
