[Okyou] Taking Off In The Wrong Direction (COMIC Anthurium 2022-05) [Nisor]

A hardworking track team junior is over the moon when his statuesque captain praises how fast he's gotten—until after-hours cleanup ends with the clubroom door clicking locked and her admiring smile curdling into obsession. Pinning him down with sweat-slicked strength, she growls that he belongs to her and sets out to teach him the 'rules of nature,' mounting and riding him relentlessly while his stunned protests go nowhere. Okyou's yandere femdom one-shot turns senpai devotion into possessive, breathless territory the junior can't outrun.
