学校では友達もいなく、空気のような存在で、いつしか引きこもり不登校になってしまったしおり。ある日、家庭訪問に訪れた担任の先生に襲われ、強烈なイラマ指導を受ける。きょどり、耐性無し、拒否反応、の初々しい喉バージンリアクションがリアル。男のS心を刺激する。次の日、しおりは半年ぶりに登校。通学途中、先生に引っ張られ物陰に。そこで再び喉奥指導。マスクの下にボールギャグディルドを咥えさせられていて、イラマスク責め。学校では、放課後クラスメイトに呼び出され「俺たちが友達になって遊んでやるよ」と、集団イラマ。さらに腹パン、蹴り、ビンタ、水責めすっぴん晒しと、仲良く遊んで（？）もらう。胸糞注意のバチボコプレイの連発で、苦しく辛いはずの行為だが、これまで孤独だったしおりは、初めて‘自分に向き合ってくれた’と脳内変換され愛の錯覚。M気質も相まって、しおりもじょじょにマゾ覚醒していく。この狂った世界が私の居場所だ…（しおり）
Shiori had no friends at school and was practically invisible, eventually becoming a recluse and truant. One day, she is attacked by her homeroom teacher during a home visit and receives intense deep throat instruction. Her flustered, helpless, and rejecting reactions as a virgin throat are realistically portrayed, stimulating the sadistic desires of men. The next day, Shiori returns to school after six months. On her way to school, she is pulled into the shadows by the teacher, where she receives deep throat instruction again. She is ****** to wear a ball gag dildo under her mask, subjected to deep throat mask *******. At school, she is called out by her classmates after class and subjected to group deep throat *******, with the classmates saying, "We'll be your friends and play with you." Furthermore, she is subjected to punches in the stomach, kicks, slaps, water *******, and ****** to expose her bare face, all as they "play" with her (?). A series of brutal and disturbing acts that should be painful and difficult, but Shiori, who had been lonely until now, mentally interprets it as the first time someone has "faced her," creating the illusion of love. Combined with her masochistic tendencies, Shiori gradually awakens to her masochistic side. This crazy world is where I belong… (Shiori)
