Has anyone else on here ever had a threesome with another couple? I thought I'd post my experience - and would love to hear other peoples stories... It happened after a party a few years ago, when I ended up sharing a bed with my mate and his girlfriend. As far as I knew we were just crashing out in the upstairs bedroom of a crowded house - and we were all pretty stoned and a bit drunk too. I was trying to get to sleep when they started fooling around and she rolled on top of him. Then, after a minute or two, she giggled and rolled off onto his other side, landing between the two of us with her back to me. They carried on fooling around, but whereas before it seemed like they were just having a bit of a laugh, it was starting to get very intense and breathless. It was at that point that I began to realise something was up, as she began rubbing her ass up against me - at first subtley, almost as though by accident, but gradually more and more explicitly until she was grinding into my groin. Not being the shy type, I was more than happy to cooperate, especially since i rather fancied this girl, a slim east german student who had really pretty eyes and black, shoulder length hair cut into a cute fringe. So I placed my hand on the outside of her hip and drew her toward me, pressing the hard-on that was raging in my jeans against the back of her thighs and her ass. I can't remember the exact sequence of events that led to my mate unbuttoning her blouse and unclipping her bra and me unzipping my fly, but the next thing I remember is that she had reached behind with one hand and was grasping and pulling on my big naked cock while her boyfriend had moved down to kiss her neck and breasts, which were small but nice and firm. Nobody had said anything about how far this was going to go or where the boundaries were, but, when you get that horny, instinct just kind of takes over! So I slipped my hand to the inside of her thigh, up inside her skirt and toward her panties, which I pulled to one side with my fingers. She was really, really wet, and willingly parted her lips to let me finger her, looking over her shoulder at me as I did it, which I thought was just so sexy. I don't know how much my mate knew of what was going on under the covers, but I do remember hearing him struggling to unbuckle his belt and pull off his pants at the very moment I entered his girlfriend. I think that she and I were both unsure whether it was OK to be going ahead like we were - did we need his consent at that point? should he get to go first and me wait my turn? But neither of us paused to ask as I hitched up her skirt and gently squeezed my cock into her pussy, which was so lovely and tight. As I slid inside a second time and pushed myself in all the way to the hilt, she tried to muffle a gasp by biting her hand. When he sidled back up to her all naked, it didn't take him long to realise that we had moved on from just grinding against each other: After squeezing in and out a few times, I was able to move a bit more freely inside her and I guess the squelching, slippery noises of penetrative sex - or perhaps simply the looks on our faces - had given us away. Shall I go on?
