Fellatio Kenkyuubu

Seishirou Amaya harbors a quiet affection for his classmate, Azusa Shirayuki. However, their dynamic takes an unexpected turn when Azusa approaches him with a highly unusual request: she asks if he would allow her to perform oral sex on him. Rather than a spontaneous encounter, this bold proposition is tied directly to a peculiar extracurricular activity that Azusa is involved in, setting the stage for a bizarre and intimate arrangement between the two students. Azusa introduces Seishirou to the Fellatio Research Club, an unofficial and largely forgotten student organization that once existed within the school. Though it operates outside the boundaries of recognized school activities, the club serves a very specific purpose for its members. Intrigued by his feelings for Azusa and the surreal nature of the situation, Seishirou agrees to participate, stepping into a hidden world where conventional school life does not apply. Within the secluded confines of this unacknowledged clubroom, Seishirou becomes the primary subject of their ongoing studies. Because of his notably large endowment, he is chosen as the ideal candidate for the members' dedicated practice sessions. What begins as a surprising confession of interest quickly evolves into a recurring commitment, as Seishirou finds himself at the center of the Fellatio Research Club's hands-on curriculum, navigating both his growing connection with Azusa and the explicit demands of the group.
