[Furaimai] Majime na Iinchou no Kanojo ga Sex ni Hamatta Riyuu

An earnest class rep, restrained by a black cuff, is coerced into a forbidden liaison that forces her from denial to ecstatic surrender. The tense exchange erupts with shouted refusals and a desperate promise of never forgiving, while the heated act culminates in a raw, internal release masked by mosaic censorship. Her transformation from the stern schoolgirl to a trembling, ahegao‑filled figure hooks the reader into the forbidden thrill of the story.
