Upskirt Fixation

Ariel is sorting out the college library and you are getting a good look up her skirt, she doesn't know you are stood behind her perving on her ass and panties until she has finished. When she turns around she tells you how inappropriate it is for you to be stood behind her looking up her skirt, it doesn't take her long to notice that you have a bulge in your trouser and you were clearly enjoying what you were seeing.
