Ruby Summers "New Uniform"

Ruby wants to use your college classroom to do some revision which is fine by you seen as today she is wearing one of the shortest college skirts you have ever seen! While she is sat reading her book you manage to get a peek up her tiny skirt and see that she is wearing very sexy white panties. You cant help but get a hard dick under your desk! What will ruby do when she sees the massive bulge in your trousers?
