[Nakamura Yukitoshi] Underground Athlete Maker (2D Comic Magazine Kikaikan Ningen Bokujou Vol. 2)

At AR Girls' Sports Academy, Hoshikawa's record-shattering sprint times hide a filthy secret: behind closed doors, the school's busty athletes are drugged, gagged, and strapped into training machines that hammer away at their swimsuit-clad bodies until ahegao-wrecked orgasms become just another workout. Tennis players, the swimming team, track stars — every girl is numbered like human cattle and 'shipped' off to corporate teams once her enhancement is complete, her toned ass and thighs sculpted by mechanical stimulation she can't refuse. When the champion takes the podium and credits her 400-meter victory to 'a secret,' the academy's corruption machine is already grooming the next record-holder.
