[OTOMEKIBUN (Sansyoku Amido.)] Gakkou de Seishun! 18

A track-and-field schoolgirl blessed with an enormous bust gets cornered during her morning commute when an older neighbor confronts her with a compromising video, and her plea to get off at the next stop only drags her deeper into his grip. Changed out of her plaid skirt and into gym bloomers, the trembling athlete is groped, teased with a vibrator, and pressed into servicing him until her protests melt into aching, unwilling pleasure. This eighteenth entry in the ongoing school series leaves her sweat-soaked and cumming helplessly under the thumb of the old man who owns her secret.
