My wife (C) and I (A) use threesome roleplaying in our sexlife (a lot) and have discussed having a threesome with another man or woman but we're alive to the risks that go with it and decided some time ago to leave it as a juicy fantasy unless something amazing dropped into our laps...well... We went to Cornwall for New Year and stayed in a large rental house with friends. One of these is a guy (T) who went to university with my wife, we probably see him no more than once every couple of years now. He was coming down with his girlfriend but arrived without her announcing they'd split up over Christmas. He did not seem devastated! He seemed relieved and up for a party. We sorted out rooms and given the house was stuffed we put a spare mattress in our room for T. The evening was amazing, everyone was nicely drunk, there was some mild but hilarious scandal and by about 2am most people had gone to bed, including my wife. T said he was also ready to crash and joked about not wanting to go in without me in case C thought he was trying to get in her knickers, I blurted out that this was a fantasy of ours anyway so not to worry. He looked shocked and I said, "not to have sex with you! But a threesome you know, a bucket list type fantasy." He said that he'd actually had one with an ex whilst on holiday, two girls and him and it had been amazing. We were talking about his threesome experience as we went upstairs and I was starting to feel that unless C was absolutely dead to the world that we might end up having to make a call on whether to convert from fantasy to reality. I looked at T and suddenly thought "do I actually want you fucking my wife?" I could feel myself getting hard by way of an answer. "Would you be up for it if C was?" I asked "Are you joking? Yes! I always thought she was hot. And your beds massive." which made me laugh. We went into the dark bedroom and C asked, "what are you two going on about?" "T was telling me all about the threesome he had." I told her She turned her light on immediately and sat up in bed, "No! Really? With Em?!?" T was kicking off his shoes and sat down on the end of our bed to take his socks off. "No way! She'd never have tried anything as wild as that. I never even told her I'd had one. Remember Clare?" C shrieked with laughter. "At university?!?" "No when we were in America." He started to describe the night in great detail. I went into our en-suite bathroom and brushed my teeth listening and thinking, "here we fucking go!" When I came T was describing the two girls kissing iand had taken his shirt off and was unbuckling his trousers. C was sat up, wearing a t-shirt as pyjamas, her nipples looked like, well like erect nipples through a really thin white t-shirt. I stripped off to my boxers and jumped in bed and put my arm round C who snuggled in against me. T started to describe having sex with the other girl while she went down on Clare. C was goggled eyed. T hadn't taken his trousers off yet and asked if C had ever had a threesome. "We've talked about it." said C I had been letting my hand wander up and down the outside of her thigh and now moved to the inside. Her legs parted a little and I traced a finger across her panties over her sex, I could feel her warmth and wetness through her panties. "Aren't you taking those trousers off?" she asked T. "Can't, I've got a bit of a hard on." "Lets see it then." she said. Under the covers she spread her legs and pushed her sex against me. I pulled her panties to one side, she was so wet, she gave a little gasping sigh as I slid a finger into her. T dropped his trousers to reveal a very nice thick cock. " Are we having your threesome then?" he asked C looked at me and said, "Well A's already fingering me...so..." and I said, "looks like it!" C pulled off her t-shirt and said, "we can't be too noisy." T pulled the duvet off the bed and C went down on me with her bum pointing at T. He moved behind her and gently eased her knickers down and off. "I always liked you bum." he said, she arched her back a little and parted her legs and he felt her wetness first, fingering her and then moved in to kiss and lick her pussy. I could see her frown in pleasure and she moaned with my cock in her mouth. The sight of someone behind my wife, knowing they were licking her pussy, hearing the wet sounds. Fucking amazing. He must have done wonders because in no time she was shaking and falling forward in the most enormous orgasm, furiously wanking my cock into her mouth. I had to pull away for fear of cumming too quickly and C spun round and started to blow T. I sat back for a minute letting my orgasm subside and gently stroking myself as she blew him. My wife with another man's cock in her mouth... She started to weave her bum at me and I knew she wanted me inside her. I moved into position and gently slid into her, my god she was so wet. I started to sloooowly fuck her from behind while she sucked T's cock. It felt fantastic and just looked so dirty. He was kneeling up holding her head gently with the palms of his hands looking at her as I started to gradually build up my speed. I really went for it for maybe 10 strokes before having to pull out again, on the brink of cumming. "Sorry! I'm going to cum if I carry on!" C's pussy was open and soaked, her pubic hair a wet mess. It looked lovely and I stuck my face into it as she carried on blowing T. She was so sensitive she started to cum immediately and fell forward into T's lap. "Fuck me." she said, "I need to be fucked." "I'll cum as soon as I'm in." I said, "Your turn T." He knelt up stroking his cock and C turned round on all fours looking back at him, "here's that bum you like so much..." He gave a grunt of lust and slid his cock all the way into her with a long groan. As I had he started super slowly which C likes, pulling his cock all the way out before slowly sliding all the way back deep into her. She started to give a little quiet dirty talk as he fucked her, "that feels amazing. Your cock feels amazing in me. Fuck me T, fuck me..." that kind of thing, it had me hard as a rock and he started to build up his pace. I was so hyped now I knew I had to cum. I moved in front of C again and she greedily took my cock in her mouth. "Give it to her T" I said and he started to really pound her her, she was squealing in pleasure with each thrust, he was grunting as he fucked her and I came as hard as I've ever cum into her mouth. Fucking incredible. I had always been scared of the post orgasm blues having a really negative impact on a threesome but for some reason I didn't feel that. It was like my sexual experience was still somehow carrying on through their fucking. I lay back incredibly content as they fucked. T was ready for his orgasm as well and C was face down and arse up as he took her and came in her and they collapsed forward with his cock still in her. "Wow." mumbled C, "wow." We all got cleaned up and had a giggle, in the loo we had a moment alone and I asked if C was ok about it, she said "yeah, really ok, it was just super hot. You ok?" "It was amazing. Better than I'd fantasised." We all got into the one massive bed with C in the middle and crashed out. In the morning there was much groaning with hangovers, T went and got some teas and paracetamols and we lay in bed together, the rest of the house quiet. We had some post match analysis about how good it had been and about how we weren't going to tell anyone. I ran a bath and T asked when we were going to have our hangover sex. C and I laughed, hangover sex is awful and amazing at the same time. "Tell you what." I said, "I'm going to have the bath and you two can have the hangover sex, while I listen from the bathroom. If it sounds good I'll join in, but bath first." "Sounds good." said T pulling C on top of him. She groaned but started to roll and rock her hips over his groin while I went into the bathroom. As I eased into the hot water I heard my wife ask in a heavy, sexy voice, "How d'you want me?" It was just so hot listening to my wife getting fucked. I couldn't work out exactly who was doing what but the sighing, moaning, creaking bed thing and the slap of bodies couldn't have been more erotic. I got out of my bath to find C riding T, her eyes closed. I stood beside them and she took my cock in her mouth and wanked me as T thrust away underneath. He came with a shuddering groan and that made me cum as well, shooting another load into C's mouth as T emptied himself into her pussy. We all left the house after lunch for the long drive back up country and while we were lying in bed on the Saturday morning C turned to me and said, "you realise that for the first time in a long, long time you're not the last man I had sex with?! Better sort that out..."
