[Shota Mangaya-san (orukoa)] Bukatsu no Ato wa Mainichi Choukyou ~Nakadashi Shiru mamire de Kyousei Shasei! Nikubenki Gakari no Kichiku Rinkan~ {Chin²}

A timid first‑year student is dragged into a brutal after‑school training where a group of older boys force a tail plug into his ass and make him endure relentless anal abuse, his body convulsing as he is reduced to a helpless sex toy. The panels show his panicked cries, cruel taunts, and thrusts that push him toward repeated orgasms while his mind shatters under the humiliation. The story builds a tense, erotic power struggle that leaves the reader wondering whether he will ever break free from the cruel training.
