Please Professor

Kylie has asked you if she can borrow some of your personal books but you don't want her to take them away with her in case she loses or damages them, she is leant over your desk making notes and your eyes get drawn to her breasts. She isn't wearing a bra and while she is leant over you are getting a great view down her blouse, Kylie notices you looking and decides to make a mutually beneficial deal.
