A lot of her looking around afraid that she's going to get caught. The irony is that the 30 minutes spent rubbing her twat in the library will probably make her more money than the hours the majority put into their textbooks.
I think the full video is 17 minutes (that's the one I found). I thought it was awesome! She's got some very nice hooters!
I'm just having some fun with you Beavs. If I ever got around to getting off of my ass to finish college i'd probably transfer to OSU anyway, especially if they have girls like this masturbating in the library.
