The library's dim lighting casts long shadows, accentuating the librarian's curves as she shelves books, her mind wandering to illicit thoughts. She can't resist the urge any longer, disappearing into the stacks to satisfy her craving. Her skirt hikes up, revealing her toned thighs, as she leans against a bookshelf, hiking one leg up to grant herself easier access. Her fingers dance over her clit, sending waves of pleasure through her body. The sound of pages turning fills the air, echoing her increasing pace, until a creaking floorboard alerts her to an intruder. Hastily, she rights her clothing, her heart pounding, as she silently vows to continue her self-indulgence another time.
