Housemate's Arrangement

Ivy is stuck on her assignment and she needs some peace and quiet, she definitely can't concentrate with you trying to get a look down her blouse. You have always fancied Ivy and you know she doesn't wear a bra when she wears her blouses, you are currently trying to get a good look at her boobs so Ivy decides to offer you a deal. If she agrees to let you look down her blouse while having a wank you have to agree to give her some space so she can finish her assignment.
