Dan had told me a couple of times in the past, when he had got a good look at my cock, that he thought I had a nice one and kinda joked about how big ...t was, but I had just blew it off as guy talk. I was beginning to see that he might have been trying to come on to me and it was making me hot and horny as hell that we were here alone, half naked, touching each other watching a hot porno movie with guys sucking and fucking each other.My cock was starting to get hard and I was starting to loosen. "Merry Christmas, Mister Desmond. Is Santa Claus ready to deliver my present down my chimney?" She reached up and drew my head down onto her breasts. The shirt was unbuttoned to her waist, and I had my mouth around her nipple before I knew it. I sucked, savouring the taste of her, feeling the erecting flesh against my teeth. My prick awoke from its slumber."I believe it time for some more cheating," she breathed in my ear, and took hold of my rapidly swelling prick and guided me into her. It was mid-summer and the air conditioning was faulty, so most people were subdued and lazy in the heat. Lots of exposed flesh and sweaty bodies were lounging about; some of the bodies were very easy to look at. I was in a pair of green knee length combats and a tight white vest top showing my toned arms and chest. Kay wore a little blue summer dress, low cut with straps over her shoulders nicely showing the shape of her breasts. The bottom of it reached mid thigh giving a great view of her. The music pounded around us. People walked back and forth, laughing and talking, not six feet away. We were as oblivious to their presence as they were to ours.As ludicrous as it seemed, given the situation, it was the first time in my life I really felt like a man. It was also to be the only time.I don't know how, but Gwen and the others could tell. Perhaps it was a glazed expression on my face when I walked in on Monday morning. Perhaps I was staring dreamily out into space at my desk..
