I approached the door and pushed it just a crack open. Charlotte was naked, on her knees, with her hubby mounted behind ramming in and out of her. I c...ouldn't see whether it was her arse or pussy that he was fucking, but the look on her face, the erect nipples and the smell of sex had my hard again.I stood, watching, rubbing my cock through the fabric of my trousers. I pulled the zipper down, and released my hard cock, rubbing it's length while I watched Charlotte being fucked hard by her.

After everything we'd talked about, she was making jokes about this?Heather must have sensed my frustration, for she quickly stood and walked over to me."Oh, Daniel," she said,.
