Hanging out in my new room

Jim helped me get the few things I owned to the new house, I own just enough things to fill my bedroom. As I sit on my bed, watching some tv in my underwear, I see Pam walk into the bathroom that connects our rooms, she's wearing a tight white tube-top, thin enough to see the shape of her 34C tits with erect nipples, and skimpy red panties that barely cover anything. She pushes the door to my bedroom shut to give herself privacy, but it doesn't latch hanging slightly open, and she doesn't notice.

From where I'm sitting on my bed, through the crack in the door, I can see her reflection in the mirror. Her reflection is facing away from me, and I can see her big butt eating her thong. She bends down as she pushes off her panties, and my dick swells. I push the band of my boxer briefs under my balls, rubbing my shaft, and my cock begins to firm up. She throws her tube top on the floor, but I can only see her back. The door creeks open a little more, and she turns around to look. I see the totality of her fit body, and her perky tits, still idly rubbing my cock which is now fully erect (8"). She approaches the door again, which I anticipate her to shut. But she opens it, and reveals her self in my door way...
