My buddy Carl and his wife Gail were swingers, and I had fucked Gail on several occasions, with Carl’s knowledge and consent.

Carl was hoping to get to fuck my wife Sylvia in return, and I had no objection to that. The problem was that Sylvia was something of a prude, and wasn’t all that wild about sex in the first place. The one thing that seemed to loosen her up was when she had too much to drink, so one day Carl, Gail and I hatched a plan to take her out for dinner and dancing, to make her feel relaxed and see how far we could get her to go.

We had a couple of bottles of wine with dinner, and Sylvia was starting to feel pretty good. At one point I rubbed her thigh under the table, and she didn’t push my hand away as she normally would have, so I took that for a good sign.

After dinner we went to a club, where we found a table next to the dance floor and ordered some drinks. When Sylvia and I got up to dance, my wife cuddled close to me and started humping my leg, so I knew the alcohol was having the desired effect. I actually fondled her breast while we danced, and she made no objection. Gail and Carl were dancing close by, and I made sure that they could see what I was doing.

After a few dances we changed partners. By this time Sylvia had had several more drinks, and was having trouble keeping her balance, so Carl had to hold her up as they danced to a slow song. She was grinding his leg between hers, and he had both hands on her ass, holding her close. When they returned to the table he had his arm around her to keep her upright and was groping her tit, but if she was aware of it she didn’t seem to care.

When we left the club Carl suggested to me that Sylvia sit in the back of the car, between him and Gail, so they could go to work on her. In her drunken state, Sylvia made no objection to this unusual arrangement. I adjusted the rear-view mirror as I drove so I had a good view in the back seat. Carl had his arm around my wife as she leaned into him. When he started kissing her she protested weakly, saying he shouldn’t do that, as Gail was her friend. Gail told her to just relax as she slowly lifted up Sylvia’s top and pulled one of her tits out of her bra, telling Carl he should suck on it. Sylvia started to protest again, but Carl just kept kissing her and fondling her tit, while Gail rubbed her tummy, her hand moving down toward her crotch.

By the time we got to our house, Sylvia’s top was completely off, and she was moaning softly. The two of them helped her out of the car, and Carl and I put our arms around her, each cupping a tit as we walked her to the house. Once inside, Gail finished undressing her, then led her to the bedroom. Sylvia was mumbling something about how she couldn’t do this, it wasn’t right. Gail ran a hand between my wife’s legs to feel her wetness. “Your mouth says no,” she told her. “But your pussy is telling a different story.”

Sylvia gave up all attempts at resistance as they laid her out on the bed. Carl got between her legs, kissing her thighs and fingering her wet pussy before diving in face first. This brought loud moans from my wife as she grabbed the back of his head, pulling him tighter against her and humping his face until she came.

Gail and I quickly got undressed as we watched what was going on. Carl now moved up and slipped his fat cock inside my wife’s pussy. I knew this was her first time being fucked by another guy since our wedding. She was moaning and whimpering with pleasure, and her moans only got louder when Carl told her she was his slut, and that from then on she would be his to use any time he wanted. “Oh, yes!” she cried, surprising the hell out of me. “Use me, make me come with your big cock, I’ll do whatever you want, just keep fucking me!”

Carl fucked her for several more minutes, but stopped just as she was approaching orgasm. He started to pull out, but she wrapped her legs around him, begging him to make her come. Carl grinned at me and told her that if she wanted to come she had to suck my cock first. When she said she didn’t do that, he just pulled out of her completely, as she continued to moan and beg.

At that point I moved up close to her, bringing my cock to her mouth. She opened up enough to take just the head of it in, sucking on it halfheartedly, until Carl told her that wasn’t the proper way — she had to really suck on it and make me come in her mouth, or he would leave. Sylvia then tried harder, taking a little more of my dick, until Gail got impatient and said she would show her how to do it. With that she got on her knees, pulled my cock away from Sylvia and engulfed the whole thing down to the base. After a few good sucks she gave it back to Sylvia, telling her to do the same. She then started to suck on Sylvia’s tit, which made her moan around my cock and start sucking for all she was worth.

Carl moved back to her then, sliding his dick inside her. Sylvia was twisting and squirming with Carl’s cock in her pussy, mine in her mouth and Gail sucking on her tits. I came in her mouth, and Gail told her to swallow my jism, which she did as best she could. A minute later Carl brought her to an earth-shaking orgasm that left her panting and gasping for breath.

Gail then climbed on top of Sylvia and began cleaning up her pussy with her mouth. Sylvia was shocked at first, but soon she was obviously enjoying what Gail was doing. When Gail turned around and pushed her delicious pussy into her face, my wife reciprocated, and soon Carl and I were watching our wives twisting wildly with pleasure as they brought each other off.

Gail then said it was her turn to take on both of us guys. Carl lay down on the bed as Gail straddled him, sliding his cock inside her wet pussy, while I grabbed some lube, spread it over my dick and worked my way into her very tight ass. At one point Carl told Sylvia to get behind me and lick my ass as I fucked his wife, and she did so without hesitation. It turned out to be a great night!

After that Sylvia did become Carl’s slut, and mine too, doing whatever we told her, including fucking other men and women in front of us. Needless to say, I have enjoyed the change in my once prudish wife, and I will tell you more about our sexual adventures in the near future.
