Ashley has come round to help you out with your university work, she had the exact same assignment last year and thinks she will be able to get you a good grade. As she goes through the book with you though you get distracted by her cleavage, she isn't wearing a bra today and when she leans over in her low cut top you get a great view of her tits. It doesn't take Ashley to notice that you attention is on her tits instead of the book and she decides to let you get your hornyness out of your system.
