A high school girl finds herself in an escalating physical relationship with her male teacher after he penetrates her with the claim that placing only the tip inside does not constitute sex. What begins as a sudden, forceful encounter during which he continues thrusting until she loses consciousness soon becomes a recurring arrangement framed by his persistent rationalization. The teacher exploits his position of authority and the girl's naivete, gradually pushing past the boundaries of what he defined as permissible under the pretense that each new act still does not qualify as the real thing. The story follows this power-imbalanced relationship as the girl struggles to reconcile her growing physical response with her understanding of consent and violation. Set primarily within the school environment and private spaces where the teacher asserts control, the narrative focuses on the psychological manipulation and the gradual erosion of the girl's ability to resist or define what is happening to her. The central irony of the title is reinforced throughout: the teacher's verbal distinction between his actions and sex is repeatedly contradicted by the reality of the encounters, creating a tense dynamic of denial, complicity, and abuse.
