[Yaza Daichi] Kinbaku Seidorei Choukyou Gakuen [Toyo Trans]

Kurihara is a freshman trapped in an academy where rope binds her body and rules bind her mind—a place where her captor promises that ranking in the top ten on the final exam is her only path to contacting the outside world, all while reminding her she's too stupid to manage it. Bound, gagged, and blindfolded, she's passed around and trained until she can't tell whose cock is inside her anymore, only that it feels too good to resist. Between shibari sessions that leave her trembling and tearful, her master dangles freedom just out of reach, ordering her to study hard and call her parents for expulsion—as if escaping a school built to break her into a cock slave were ever truly possible.
