On the night in question Robin picked up me and Sonia and took us to a Hotel suite. Sonia and I wore business-like clothes on top so as to not cause t...oo much of a stir as we passed through the Hotel but underneath we both had on really sexy underwear and stockings.We used the bathroom amd came out in our undies. I could see Robin for one had his tongue hanging out.We undressed each other as slowly and as sexily as we could and lay on the bed and put on a really dirty show for the guys -. I grabbed the last box, and took it to the street, as I did the pizza arrived I paid the guy and took the pizza inside. She had gotten dressed, in a sleeveless top and tight jean shorts, and come out of her room, “oh, great the pizza’s here just set it on the table I’ll get some plates and cups, she went to the cupboard and reached up (in futility) “Matt, can you grab the pizza tray for me?”“Sure,” I said as I came up behind her still semi-erect from thoughts of her I inadvertently pressed. But I was discovering tonight that we were not a ‘normal’ husband and wife, we were different from other couples, we enjoyed and craved the pleasures that ‘normal’ couples would not allow themselves. I had thought I was the one in our marriage that was hiding my perverted passions, but Sarah obviously had her own passions that seemed as perverted as my own. As I was concentrating on watching my wife on the screen expecting another hard cock to be forced into my mouth, Peter had another idea in. My hair lay matted against my head from sweat and I wondered if Chris's mum had turned up the house's heat.Chris's mother was unique and she was a stunner. I took quite a fancy to her and often had fantasies about playing with her when Chris was not around. She doesn't look like your typical mother, with the fact she looks more like an older sister than anything. I don't come to Chris's house often but when I do, I look forward to any encounter with her. I remember one morning, our first.
