Cleaning Cleavage

Katie is showing you around the room that she will be renting out once her current roommate moves out, she has left it in a bit of a mess so Katie tells you that she will give it a quick tidy up while you wait so you can see the room properly. As she leans over to pick up some clothes off the floor you realize the shirt she is wearing is unbuttoned so much that you can see her breasts, she isn't wearing a bra and you can feel yourself getting aroused.
