We had just sat down for our evening meal when Gabriella said she had something to ask me. I told her to go ahead. She came right out with it, "I want us to have a foursome." I nearly choked on my food. I checked with her that I had heard right and she confirmed that I had. I thought for a few moments and the thought that I would get some fresh pussy had me salivating. Then she ruined it. She wanted three men and her not two couples. I asked what had brought this on as in our four years of marriage there had never been the slightest hint of her wanting to stray from our marital bed and up till now I had been totally faithful. I could see her knowing that I had loads of questions. "What's brought this on," I asked and she told me that she had been talking with Sharron at work and she had been in several threesomes and foursomes and had described them to her. I wouldn't have minded a threesome or foursome with Sharron as she was gorgeous. It had got Gabriella all fired up and excited. I asked was it any men or did she have some in mind. I was pleased that I was one of the three and she told me that she had two others in mind. Of course I asked who and she told me that they had two men from their Australian office over for a couple of weeks and she doubted that when they went back she wouldn't ever see them again. I certainly wasn't happy that she got three cocks and I didn't even get any pussy. Then she made it clear that it was going to happen with or without me. What choice did I have if I wanted her to stay with me, and reluctantly told her yes, but it would be the one and only time. She came home the following evening with an extra bounce in her step. Over dinner she informed me that it would happen on Saturday night. She had invited them to dinner and afterwards she was hoping they would come around to her way of thinking. Dinner was ok and then we were sat in the lounge with Gabriella between them on the sofa. Gabriella told me to break out some brandy. That on the top of the two bottles of wine should grease the wheels as they say. I noticed that Bruce already had a hand on Gabriella's knee. Then as she turned to face Robby he planted a kiss on her lips. It had started and I had a clear view from my favorite chair. After Bobby's kiss she turned to Bruce and he took his turn to kiss her as his hand went up my wife's skirt. I heard Gabriella gasp as he touched her pussy through her panties. Robby wasn't idle, he had grasped my wife's tits through her blouse. It wasn't very many moments before Robby was relieving my wife of her blouse and bra. Bruce broke his kiss to take one of Gabriella's nipples in his mouth. Gabriella groaned as he sucked a good amount of tit in his mouth with her nipple. Then it was like a free for all and clothing was flying everywhere. The men were both naked as was Gabriella. She was sucking Bruce's cock as Robby sucked and licked her pussy. Even with her mouth full of cock she was still able to moan as Robby sucked her clit and licked her crack. I had got in on the act and besides kissing one of her tits Gabriella was using a hand on my cock. Then Robby was putting Gabriella on all fours and before Robby had the chance Bruce got behind Gabriella and beat him to my wife's pussy. Gabriella groaned extremely loudly just before Robby filled her mouth with his cock. She was still moaning but it was now muffled. I was fondling one of her tits and she was still trying to wank me, but not very successfully Bruce didn't last very long before he hollered and pumped his seed into my wife's pussy. It then dawned on me that we used condoms and Bruce was bareback in my wife. To compound the situation Robby quickly replaced Bruce and he was also bareback as he plunged in and out getting sloppy seconds. Gabriella pulled me towards her and took my cock in her mouth. I couldn't remember a time it was that hard. A few minutes later Robby pumped a second load in my wife's pussy. She pushed me from her mouth and stayed on all fours. I knew what she wanted and moved behind her and slipped my cock all the way in with one push. It felt strange her pussy was so wet and loose, nothing like it normally felt. I decided that if she was to get pregnant it should be mine and I wanted my semen to have the best chance and rammed as hard as I could and pumped my load as deep as I possibly could. Then we were all sat around naked. Gabriella suggested more drinks and I cracked open another bottle of wine for Gabriella and beers for the men. Both Bruce and Robby were telling me what a fantastic woman my wife was and that I was a real sport for letting them have her. I must admit I felt proud of my wife even if she had just acted like a slut. Then I noticed that Bruce was ready to go again. It wasn't missed on Gabriella who pulled him on top of her as she lay on the sofa. Bruce had her legs high in the air as he penetrated her again and the her feet were on his shoulders as she slammed away again at my wife's pussy. Robby wasn't about to miss out and turned Gabriella's head so he could put his cock back into her mouth. She was again moaning around a mouthful of cock. Bruce lasted much longer this time before he pumped a fourth load into Gabriella's pussy. As Bruce pulled out Robby held her legs up and took Bruce's place and slammed straight into Gabriella's pussy. Robby didn't take that long as Gabriella groaned through the banging she was getting from him. Then like Bruce he dumped another load in Gabriella's pussy. I could see it trickling down her pussy and arse onto the sofa. I needed to even load and the chances of any offspring to be mine so I went to lift her legs again as Robby had let them down as he withdrew. Gabriella told me to leave them down as it was getting uncomfortable with them up. I slipped into her with one partially up and the other with her foot on the floor. I took my time as my cock sloshed around in a sea of cum in my wife's pussy and slowly pumped her towards a heavy climax. She moaned and groaned through it until she came and then I followed her and dumped my final load. Shortly afterwards Bruce and Robby dressed and after shaking my hand they left. We had a very nervous few weeks until Gabriella had her period. I was very relieved as was Gabriella who hadn't thought about contraception or the consequences of not bothering before hand. It was a few months later Gabriella organized a threesome for me with Sharron from work. She also told me that she would like further threesomes with another man telling me that two additional men was too many. I told her I couldn't risk her getting pregnant by someone else. She told me no problem as she had been taking the pill for just over a month and was now safe. That started us on the road to regular wife swaps. It was a few years later when Bruce and Robby came back to the UK for a holiday. No need to tell you Gabriella's reactions. All I will say is that at the end of their stay they went back to Oz very happy.
