Lexi just doesn't care and will wet anywhere. Lexi was thinking about all the places she has wet herself and after seeing another video she realized she has never wet herself in a library before. Lexi tells you she wants to pee herself on purpose in the library because it turns her on. Then Lexi casually walks around the library peeing her pants and looking at books. You can hear all the people around her talking but Lexi just doesn't care.
