Dolly is so grateful you have helped her out by finding a few books for her to read, she has been struggling with her assignment and can't wait to start reading. As she flicks through the books you notice that she is wearing a bra, while she is leaning over the book you are getting a great view of her tits and cleavage. Dolly looks up and catches you looking down her blouse, instead of telling you off she decides to show you how grateful she is for your help!
