ほぼ女子しかいない学校でイジメられ、下僕のような扱い受ける男子。ある日転倒し頭部を強打。そして教室に戻ると…女子の頭の周辺に何やら数字が？なんだアレは？と思案を巡らせているとうっかり強気女子の会話をシカトしてしまった。それに腹を立てた女子が追い打ちをかけてくる。あまりにイライラしていたボクは「少し黙ってくれ」と思わず胸ぐらを掴んでしまった…。するとあの頭の上の数字が急上昇！えっ？これってまさか女子のM度数？つまりは犯●れたい願望？無理矢理強引にSEXしても怒られない確率なのでは？？今まで弱気で一度も反抗しなかったけど、もしボクが本気で反抗したら女子はボクの支配下に置けるということ？よし！これがわかればもう無敵！ガンガン強気で女子を追い込んでボク専用の肉便器してやる！ビンタ、首絞め、思いっきりやってやる！これまでの恨みを一滴残らずマ○コにぶち撒けてやる！もちろんイジメを黙認した女教師にも！

A boy is bullied and treated like a servant in a school that's almost entirely girls. One day he falls and hits his head hard. When he returns to the classroom… he sees some numbers around the heads of the girls? What are those? While he's pondering this, he accidentally ignores a conversation between some assertive girls. The girl gets angry and adds insult to injury. He's so irritated that he grabs her by the collar and says, "Just be quiet for a bit." Suddenly, the numbers above her head shoot up! What? Could this possibly be the girl's masochistic tendencies? In other words, her desire to be d? Is it the probability that she won't get angry even if he forces himself on her? I've been too timid to resist until now, but if I really resist, does that mean I can put girls under my control? Yes! Now that I know this, I'm invincible! I'll be assertive and corner the girls, turning them into my personal sex slaves! I'll slap them, ***** them, and do it with all my might! I'm going to unleash every last drop of my resentment into her pussy! And of course, onto the female teacher who condoned the bullying too!
