A boy is bullied and treated like a servant in a school with almost no other boys. One day, he takes a fall and hits his head hard. When he returns to the classroom... he sees numbers floating around the girls' heads. What are those? While wondering, he accidentally ignores a strong-willed girl's conversation. Angered by this, the girl attacks him with words. Frustrated, he instinctively grabs her by the collar and tells her to "shut up for a second..." Suddenly, the number above her head skyrockets! What? Could this be the girls' M-level? In other words, their desire to be fucked? Is it the probability that they won't get angry even if he forces his way into sex? Until now, he was timid, but if he truly rebels, can he put the girls under his control? Alright! Now that he knows this, he's invincible! He'll push the girls hard with an aggressive attitude, turning them into his own personal meat toilets! Slapping, choking, he'll do it all! He'll pour every drop of his resentment into their pussies! And of course, the female teacher who turned a blind eye to the bullying too!
