NHDTA-899 A high school girl who is so horny that she can't help but do saddle onanism on her bicycle seat, which has been smeared with an aphrodisiac, even on the way to school. 4

A man follows a female student riding a bicycle and smears an aphrodisiac on the saddle when she's not looking. Unaware, the girl gets back on her bike and starts pedaling again. The aphrodisiac seeps into her vagina, causing her to become aroused... She can't hold back and starts masturbating on the saddle! Even then, the unsatisfied female student feels pleasure even when attacked! Moreover, incidents like 'in front of friends'!, 'near her boyfriend'!, 'riding a bicycle upside down'! etc. keep happening!!
