My ex and I tried this, and man, what a turn on!! We were both pretty open. We knew where each other's allegiance was, so it was nothing for us to be flirty with our friends, and vice versa. She'd flashed my best friend before, and I'd been the male dancer for one of her best friend's bachelorette party. This one night, we'd gone into town for a night of dancing and drinking. My best friend was with us, and he was feeling pretty low, due to the fact that his wife had just left him for some other guy, and he got pretty well lit. My wife wasn't feeling any pain, either. I was the only one who stayed sober, being I was designated driver. On the way home, we decided my buddy might as well stay at our place for the night, rather than trying to get him up to his place (ours was one floor, while at his house, we would've had to get him upstairs). When we got home, he very uncerimoniously staggered into the house, and flopped on our bed. I looked at my wife and said not to worry about it-- he was too lit to do anything, anyway. I told her to go ahead and undress him, so he wouldn't get twisted up in the covers, which she did. Then, with an evil grin, she grabbed him, and to both our surprises, he got rock hard immediately, her jaw just kinda dropped, and she let go. She asked me if I'd still be alright with him in the bed with us, and being my friend was about 270 lbs and built like a WWE wrestler (not a bit of fat on him), I wasn't about to move him, so I said what the hell. We both got undressed and got under the covers, with my wife in the middle, facing me. About 5 minutes later, my buddy rolled over and started spooning with my wife. She looked at me like "are you okay with this?" I just grinned, and just as suddenly, my buddy rolled back. This happened a few more times, and then suddenly, my buddy got up to go to the bathroom. Once we heard the stream from him taking a leak, she turned to me and told me that every time he'd roll over to her, he'd get wicked hard, push up against her, and then roll away. I told her the next time, go ahead and reach around and "relieve" him. She just looked at me incredulously and asked if I was sure. I told her I'd never been so damn turned on in all my life!! So when my buddy crawled back into bed, she reached around and let her "fingers do the walking". About 5 minutes into it, you could hear his breathing change, and tell he'd just shot off in his underware. Well, my wife was never one for once a night, and kept playing with him until he was at the point where he was staying hard, and without warning, he turned over again. My wife's eyes opened as wide a pie plates, as if to ask "what now!!" I just winked at her, so she reached behind her, lifted her top leg a little, and put him inside her. My buddy started rocking back and forth nice and easy, and my wife began moaning. All of the sudden she bent way over, and went down on me, and it was too much for me, I came right at her first touch. But as with my buddy, she wasn't about to stop for anything! We kept that up for about 3 hours, and man, what a night!!!!! Even now, I'm so turned on that I'm shaking!!
