Nip Slips

Ellie has misplaced a book she borrowed so she has to get on to her hands and knees to try and find it under her bed, luckily for you she is wearing a very low cut top and you can see straight down her blouse! You can feel your cock getting hard and you realise you don't want her to find the book any time soon, you also wonder if she will notice the bulge in your trousers.
