.. after I quickly downed at least one beer and hopefully two (and a small package of chips) before the sun set on another diet cheat sabbath.Certain ...hat sun had set for certain and that a third quick frosty beer would now be quite against the house rules, but with my belly a bit less empty, I braved going upstairs where I could hear loud-pitched female shrieking. For a brief moment I anticipated trouble; namely that the twins quite limited stock of patience, tolerance and understanding had. For the next few days the subject of Gary wasn't mentioned. I thought about it a lot. Could I handle the thought of her with this other man. I had done it before but the circumstances were much different. Then I thought about what I would want in return. If I let Jennifer do this, would I want to have a fling with another woman, if so, who? I decided what I would want in return wasn't important. I had to make this decision based on whether I felt comfortable letting Jennifer have sex with. Tom was drawing lazy circles around her breasts giving her pause to wonder if they had showered too soon. 'You know,' he said, 'you have incredibly powerful orgasms. Sometimes I think you may hurt yourself.' 'You know me,' she laughed, 'I enjoy everything to the fullest...especially sex. Besides, you seem to keep up with me pretty good!' This unexpected comment brought a snort of laughter from Tom. 'It's more difficult than you think,' he mused. 'Perhaps we should try more positions.' Now it. The guy I was with told me to come over there and get on his lap. His cock was out and he was stroking himself. The guy behind me pulled out of my pussy and I stood on my shaky legs and walked over to him, straddled him and reached down, grabbing his cock and holding it at the entrance to my pussy. He was thick, but familiar, and I was a little relieved to be fucking him again. I was so turned on by the whole surprise spectacle, but also incredibly embarrassed by what a slut I was turning out.
