[Yamamoto Naoki] Bunkou no Hito-tachi Vol. 3 Chapter 29

Two young classmates, a small girl and a boy, leave school together as she declares she'll prove her worth to a "retarded teacher," setting the stage for a charged dynamic of dominance and experimentation. Their tension carries into a private bedroom encounter where the boy's stiff erection and her teasing command ("Don't look over here. It's fine to dress up already.") blur the line between childish curiosity and forbidden intimacy, culminating in her guiding him into a frantic, shared climax. By the final page, the credits reveal this as a release by FaPii Scans, titled "Bunkou no Hito-tachi ~Slaves~," framing the whole chapter as a raw, taboo exploration of youthful bodies pushed beyond innocence.
