Sophie has asked if she can borrow some of your books to help with her college work, while she goes through them leaning over your desk you realise you can see down her white blouse. It's very clear she isn't wearing a bra and as soon as you see her hard nipple you feel your cock jump to attention! You decide not to tell her you can see her tits and enjoy the view while she has no clue you are perving on her.
