And what can you do when your roommate waits for you like this on your bed?

My new roommate is the weirdest thing. as soon as he gets home from work he locks himself in his room and when we pass by the house he hardly speaks to me. what a surprise i was when i got home today to find him on top of my bed and almost completely naked. yes, it is rare for a while but how does he make me see that little white and small ass open and playful on top of my bed.
