Secret Lives in mistressiside

In the silent stacks of “mistressiside,” she hides between shelves in a pleated skirt and no panties. Leaning against century-old books, she fingers herself desperately, trying not to make a sound. The risk makes it better. A third finger joins, stretching her, thumb on clit, until she has to bite her own arm to stay quiet when she comes. Juices run down her thighs in “mistressiside,” leaving wet spots on the carpet as she straightens her skirt and walks away like nothing happened.
