Over ten years ago a couple my wife and I were close to got into swinging and tried to talk us into joining them. We became more openly sexual with them, going to strip joints, watching porn together, the girls showing off their tits and kissing and touching each other. It was pretty much all harmless fun. They talked us into going to a swinger party with them. We hung around as a group having drinks and chatting with people. Seeing women walking around in various states of undress and cocks hanging out all over the place was a big change for my wife and I but she was having a good time just people watching. Our friends wandered off to have some fun and we were approached by a few couples and a few single guys but we always said we were just there to see what it was all about. One single guy though kept talking with us focusing on my wife. He was about my current age so was at least ten years older then my wife at the time. He complimented her and flattered her and she started showing interest in him. I could tell she was aroused by all the half dressed people and the sights and sounds of sex. During conversation she started touching the guy, putting her hands on his arm, leaning into him, things like that. She was totally focused on him. I started thinking she might have sex with him if I gave her the ok.

She was getting more and more into this guy. He was touching her now, his hands on her arms and then resting on her hip. They began talking about her body. She's a brunette who had long thick hair at the time with nice firm D Cup breasts. She was what they'd call thick today. Nice round ass and big tits which both me and this guy obviously favored. They talked about her tits and during the conversation she talked about being self-conscious because her tits were slightly different size. He told her it was normal and that they looked beautiful. She mentioned they might not look as good exposed and he wanted to see. She looked at me and I nodded ok, whispered to her to do whatever she wanted and then faded into the background to watch. I was nervous, torn between her actually being with someone else and the excitement of watching her have actual sex. I was thinking this was going too far but my throbbing dick was doing most of the thinking for me.

So I watched from the other side of the room as this stranger seduced my wife. I could bits and pieces on their conversation which was exciting but watching succumb to him was more so. They continued talking about her tits and before she exposed them to him, she allowed him to feel them, squeezing and lifting, his hands running over her nipples. She was braless wearing a loose thin top and he was enjoying the feel of her breasts. She let him lift her top exposing them to him. He looked and complimented, lifting the larger of her two breasts (the difference is slight but it does bother her) then playing with her nipples. He leaned in to suck and she allowed and enjoyed it, looking over at me with a look of pleasure on her face and an awkward smile.

After a few minutes of his sucking he leaned back to compliment her and their conversation continued, he continued touching and massaging her tits while they talked which made her more and more aroused. She took off her top and stood topless in a room full of people while a stranger played with her tits. Their conversation moved onto his dick. She was looking down smiling and laughing then she took a feel which led to her squeezing and groping. Then they continued talking, him softly playing with her nipples and her massaging his dick through his pants. Soon she unzipped his fly and reached in. I was breathing heavy watching her, my dick was hard so I had to start touching myself to take the edge off.

She pulled out his erect dick which was bigger and thicker than my own. She was obviously impressed and excited softly stroking him and talking about how big he was. To that point my wife had only ever been with me. I'm not small by any means but he was substantially bigger and her curiosity and lust was obvious. Then she knocked me sideways, dropping to her knees out of the blue in front of this guy, holding his cock in one hand by it's base and then taking it slowly into her mouth. She slowly sucked his cock, her lips moving around the head, head bobbing slowly, her free hand roaming over the guy's body, feeling him and occasionally yanking his nipples. He removed the rest of his clothes while she sucked his cock still moving slowly taking him about halfway in as the pleasure she gave him shown on his face. She continued, working him deeper and deeper and eventually she stopped sucking and forced his cock down her throat. She was a great deep throater with me but I was surprised she was able to do him but she was. She took him deep to his balls over and over while massaging said balls, he was moving his hips. She settled in under him, sucking and deep throating really enjoying herself, his hands now in her hair gripping and pulling in time to his more vigorous thrusting. It started to look like he was going to cum. I noticed that I wasn't alone watching her suck his dick. There were a few single guys and couples all there enjoying themselves and watching her in action. He pulled her hair tight and groaned and shuddered and then moaned over and over. I knew he was cumming. My wife's mouth was sucking as he pumped his dick and pulled her head down on his cock. Twenty seconds later it was over, he released her head and she tenderly sucked on his cock until he was completely relaxed. I heard comments of approval from several people in the room.

I thought it was over but he was just getting started. He lifted her up off the ground then kissed her deeply which surprised me considering she had just swallowed his cum. He brought her to an unoccupied ottoman and lay her down on it. He removed her pants and her panties stripping her nude in a room full of strangers. They made out intensely followed by him sucking hard on her tits, massaging and squeezing. Other people were fucking in the room but most of us were watching my wife and her lover. Her legs were spread and he was between them his hands circling her tits, mouth going back and forth, hands feeling her body, her hips, thighs, stomach and ass. Looking at her it was so obvious she needed a good fucking and he was planning to give it to her. He worked his way down to her pussy. He licked and kissed, rubbed and fingered, fingers entering her, circling her clit, pumping in and out, her breath fast and deep, eyes closed, focusing on her pleasure. Her body totally exposed now, all of us watching her squirm, seeing her grabbing his head directing his mouth to her clit, seeing her arch her back, a hand grabbing and twisting her nipples in turn, a loud "ahhhh" as she shuddered, then stiffened and came, muscles tensing, jaw clenching, she came hard, one woman in the room saying "yay" drawing laughter as my wife bucked her pussy just so until she too relaxed just as her man friend had when he came in her mouth. He stayed between her legs for a long time gently teasing her pussy and feeling her body.

When he was ready he sat up, his cock stiff and rigid pointing directly at my wife's wet and willing pussy. The guy walked to a table and selected a condom. He gave it to my wife who opened it and put it on his dick for him, rolling it down it's length. Then she lay back, legs spread, wet waxed pussy exposed, open and ready, breasts hanging slightly to the side, nipples hard. He started by rubbing his dick up and down her slit, splitting her thick lips, rubbing her clit, her moaning in response. He slowly pushed in his cock head, stretching her, her moaning, him withdrawing, over and over, going deeper each time, her hips moving, pushing her pussy at his dick, trying to get it all, her legs spreading wider, him smiling, looking over at me then plunging deep inside her with a hard hard thrust, his cock banging hard enough against her cervix to draw a loud gasp from her and some "oohhs" from the women in the room watching.

He was ready now. He fucked her and fucked her hard. Each thrust long and deep, his balls slapping, her grunts in time with his slamming cock. Her cries drawing comment, her gripping the ottoman, holding on for dear life, her tits bouncing up and down, up and down, my cock throbbing, I took it out to stroke while watching my wife get the fucking of her life.

He lifted one of my wife's legs and it allowed him to somehow go deeper with his thrusts. She was rolling her hips, bucking her pussy at his cock getting closer and closer to orgasming. I moved closer to see her more clearly. She would look to me with a strange look of worry on her face then look back at him and close her eyes and moan to his thrusts. He fucked her faster as he got close to cumming which made her hang on and say "oh yes". I was looking down at her, ecstasy on her face, both he and she close to cumming, her tits bouncing and bouncing as he thrust deep inside her. The thing I think of most was the look on her face and her beautiful tits bouncing to his thrusts.

When he was ready he laughed and kinda yelled and hard thrust deep inside her. She lifted her hips and her body froze, she moaned and came, her body now stiffening, her jaw clenching like always, her eyes closed hiding from the room. His deep thrusts making her tits bounce harder. Slower but harder.

He took his time pulling out and then gave one of her tits a playful squeeze and nipple twist, gave her a deep kiss and was off to clean up. My wife just lay there for a few minutes, legs still opened, breath slowly returning to normal. I helped her up and after getting dressed we headed home where we fucked. I fucked her and fucked her. It was a great night of sex. A few weeks later while talking about going to another sex party my wife said that she wanted to wait. We're still waiting. She later explained that she loved it, loved the atmosphere and loved the sex and found herself thinking of it all the time after. She couldn't get that guy out of her mind and started thinking of ways she could fuck him again and again and realized it could ruin things between us. Even though she loved it she was reluctant to risk what more sex outside our marriage could do to it. I tried to convince her we could manage it but so far she's only hinted about doing it again, she's never actually agreed to and it's been ten years.
