In a bustling school setting, the story unfolds with the arrival of a new teacher, 吉見ゆりや (Yoshimi Yuruya), who takes on the role of the class's new homeroom teacher. With a warm and inviting presence, she promises to make the school life enjoyable for her students. However, the tranquility of the classroom is soon disrupted by an unexpected incident during cleaning time — a student is injured, and the tension escalates as the class is drawn into the chaos.
As the investigation unfolds, it becomes clear that the injured student is the son of the principal, and the blame falls on 吉野先生 (Yoshino-sensei), the previous homeroom teacher. The principal, who had once been Yoshino-sensei's teacher, demands an explanation, and the situation quickly spirals into a personal and professional conflict.
The story takes a dramatic turn as the principal imposes a harsh punishment on 吉野先生, requiring him to take on the role of the school's "sexual processing officer." This new assignment brings a wave of intense and intimate encounters, as 吉野先生 is subjected to a series of passionate and explicit experiences with various students and teachers, including 吉田先生 (Yoshida-sensei) and 吉田君 (Yoshida-kun), who play significant roles in his transformation.
As the days pass, the once-respected teacher is gradually overwhelmed by the physical and emotional demands of his new role. The school becomes a place of both tension and seduction, as the boundaries between teacher and student blur. The narrative captures the emotional arc of 吉野先生 — from a composed and respected educator to someone who is physically and emotionally exposed, undergoing a transformation that challenges his identity and dignity.
Amidst the chaos, the story also highlights the dynamic between 吉田先生 and 吉田君, who, in their own ways, contribute to the unfolding drama. The setting of the school becomes a stage for passion, power, and personal revelation, with each scene building up to a climactic and unforgettable experience that leaves both 吉野先生 and his students forever changed.
