GS-113 - I put an adult magazine on the library shelf, and the high school girl who picked it up started getting off right there!

I planted an adult magazine on a library shelf and watched as a curious high school girl started squirming in excitement. When she caught me watching, she immediately pressed her body against mine. We ended up in a frantic, silent encounter hidden behind the bookshelves, where she struggled to keep her moans muffled while I took her right there.
