My wife Jan and I have been married for four years now, and had our first child just 10 months ago.

The birth of our daughter affected Jan in a couple of interesting and unexpected ways. First, after exercising vigorously to lose the weight she had gained during pregnancy, she went further, and managed to get herself back into the sexy shape she’d been in when we first met — except that her boobs remained at least a full size larger, which made her curvy 28-year-old body look more smoking than ever.

The other change I noticed was that Jan became much more sexually aggressive, and seemed to want to make love as often as possible. When I mentioned this to her one night, she said she thought her hormones must have changed or something, because now she seemed to crave a hard cock inside her all the time.

One day I came home from work early and found my wife stark naked and lying face down on our bed as she rode a very thick 12-inch-long dildo as if it was the real thing. I was doubly surprised at this sight, as Jan had always told me that my seven-inch dick satisfied her completely; but this thing was much longer and at least a third as thick as my cock. It was freakin’ huge!

She was so lost in what she was doing that she hadn’t heard me come in, and for the next 10 minutes I watched as my wife had four very intense orgasms with her new toy. All the time she did it she was moaning obscenities and gasping about how wonderfully full her pussy felt.

When she finally removed the dildo from her cunt with a loud sucking sound, she rolled over and saw me standing in the doorway, with a raging boner in my pants. All she said was, “Make love to me,” and I was out of my clothes in seconds. When I moved between her legs, my cock slid effortlessly inside her wet pussy. We made love like animals, and she came twice more before I poured my semen deep inside her.

Afterwards, as we cuddled, she admitted that she was constantly horny these days, and that she now masturbated several times a day. We talked for a while about the changes that had come over her, and at one point I remarked that it looked as though she was craving a bigger cock than mine. She was silent for a few moments, but then nodded and reluctantly admitted that that was the case. She said she was sorry for having those feelings, because she loved me dearly and didn’t want to hurt me. Before I could say anything in reply, she swung her body around and eagerly engulfed my entire cock with her warm mouth.

After a few moments of watching her head bobbing up and down on my shaft, I pulled her body on top of mine so that I could eat her pussy while she sucked me. As I began licking her labia she began to moan with pleasure, and spread her legs wide to give me free access to her very wet snatch. I then reached for the huge dildo she’d been playing with and brought it to her opening. As I started to push it into her she gave a cry of passion, and the cries got louder and louder as I pushed the thing deeper into her body.

When it was about three-fourths of the way inside her, Jan shrieked as her body began to shake violently. I began thrusting the dildo strongly in and out of her, which seemed to prolong her orgasm for a long time. The feel of her spasming body, along with that of her mouth sucking really hard on my cock, caused me to shoot my load into her receptive throat. I have no idea how she was able to swallow all my come while in the midst of a violent orgasm, but she did.

For the next few days I thought about what Jan had told me, and then one night I sat her down to discuss what I wanted to propose. I told her I loved her more than anything in the world, but that I wanted her to be happy. I said that since she was obviously not getting all the sex from me that she needed, and since she admittedly needed a larger cock than mine to satisfy her, I proposed that she sleep with other men for as long as those cravings persisted.

She stared at me with bulging eyes, as if she couldn’t believe what I was saying. “You would allow me to sleep with other men?” she asked incredulously. I replied that I would do anything to make her happy. What I did not tell her then was that the idea of her making it with some hugely hung stud actually excited my curiosity and aroused my lust.

I told her that I had been doing some Internet searches, and had found a couple of swingers’ groups in our area, and that if she was up for it, I thought we should contact them and see how it went. Jan sat there in rapt attention while holding my hand tightly, and when I asked what she thought of my idea she gave me the most passionate kiss of my life. Then she said, “Oh God, fuck me now, honey, because I love you so much I can’t stand it!” We then rushed into the bedroom and had one of the wildest nights I can remember.

The next day I sent e-mail letters to the two groups I had selected, along with photos of Jan and me, one of which showed my wife wearing a miniskirt and sweater that showcased her magnificent body. I heard nothing for several days, and then finally one of the groups replied with an invitation to attend one of their get-togethers the following Friday.

That night my wife was again a wildcat in bed, and we made love so many times that I had a hard time getting up in the morning to go to work.

That Friday Jan took our daughter over to her mother’s for the night, then hurried home to prepare for the party. When she came out of the bedroom I just about fell over, and my dick got instantly hard. She was wearing an extremely short black leather miniskirt and a red lace body suit that was nearly transparent. Her shapely legs were bare, and she had on a pair a red four-inch heels. I could hardly keep my hands off her, but she pushed me away, saying she didn’t want to spoil her appearance.

As we drove to the party, Jan kept rubbing my boner while telling me how much she loved me. I had to use all my will power to stop myself from coming in my pants.

We pulled up in front of a large, sprawling ranch home at exactly nine o’clock. I could tell that Jan was really turned on; her breathing was rapid, and her face was flushed. When I rang the doorbell a handsome man of about 35 greeted us with a big smile and introduced himself as Sam, the host for the evening. He led us into the living room, where a dozen or so people were drinking and talking. Some were older than we were, some younger, but the men were all handsome and fit, and the women were without exception, attractive. Though most of the women were dressed provocatively, I was proud to note that every man there was staring at my wife as we came into the room.

Introductions were made, and each man came up to Jan and kissed her on the lips, while the women did the same to me. Sam’s wife, a voluptuous dark-haired woman named Lily, made us drinks while Sam explained that all sexual activity was strictly voluntary. Anyone could approach anyone, but the person approached had the right to say no at any time.

Shortly thereafter Sam and Lily led the group downstairs, where we found a large, lavishly appointed rec room with a fireplace, numerous chairs and couches and a number of large mattresses placed around the floor. Soft music was playing through the speaker system, and the lighting was dim. I noticed an assortment of sex toys lying on a coffee table in the center of the room.

People immediately started undressing and pairing off. It wasn’t long before a man came up to Jan and took her hand to lead her to a mattress. She blew me a kiss, and I gave her a reassuring nod as she went with him. A moment later Lily, the hostess, came over and led me to another mattress.

“First time ever?” Lily asked me as we sat down. I nodded, and she smiled and told me not to worry, because everyone would be gentle with Jan — unless she indicated a desire for something else. She then gave me a kiss that would have melted snow in the Arctic winter.

The room was soon filled with the sounds of moaning, as well as grunts and gasps and the unmistakable noises of fucking and sucking. I kept glancing over at Jan as Lily and I started making out. It wasn’t long before her body suit and skirt were off, and the guy with her was starting to feast on her turgid nipples.

A few minutes later, while Lily and I were eating each other, I heard a familiar wailing sound that I knew came from my wife. As I looked over to see what was going on, Lily pulled her mouth off my dick to say, “It looks like your wife likes Ron’s big cock. He’s got ten inches of pure love meat, but wait until she gets a taste of Kit’s huge thing. He’s even longer, and he’s as thick as my wrist. I’m sure he’ll get around to her, because all the guys like new meat. Your wife will be very popular tonight.” She then went back to sucking my cock, and I resumed eating her pussy while listening to Jan’s wails and moans.

When Lily and I started fucking, I looked over and saw that Jan was still on her back, enthusiastically enjoying Ron’s cock, but that there was another guy now feeding a very long thick cock into her mouth. I assumed that this was Kit, and that turned out to be the case.

Lily was right; Jan was the center of attention that night, because all the guys wanted to sample the new girl, and they couldn’t seem to get enough. Nor could she. Every guy fucked her at least once, and she orgasmed with them all. When she fucked Kit’s cock the room was filled with her screams and shouts as she came again and again. She was also double-penetrated numerous times, and she loved it.

As for me, I bedded five different women that night, and although I couldn’t measure up to Kit and Ron, nobody had any complaints about the size of my dick.

At around one in the morning, Jan came over to me and asked if I was okay with what was happening. I smiled and kissed her, telling her I was fine. She smiled back and said, “Then make love to me.” I got on my back and she rode me cowgirl-style, her lovely boobs dancing about as she bounced up and down on top of me until we both came.

After that, Jan took another crack at Kit’s big cock while Sam took her ass. She came several times, and each time she did, everyone knew it. Watching her fuck them got me hard again in no time, and I knew that things would never be the same for either of us after this.

When Sam and Kit moved on, a busty redheaded woman named Iris, who happened to be Kit’s wife, crawled over to Jan, holding a two-headed dildo in her right hand. They stared at each other for a moment, and when Jan smiled, Iris moved up to her and they started kissing each other.

I knew Jan had never had a girl-girl episode, so I sat watching in fascination as they really got into it. They kissed several times, and then Iris sucked my wife’s breasts for a minute or so. Then they quickly moved into a 69 position and began licking each other’s pussy with a vengeance until they both came.

Then Iris turned around and smiled again, saying, “I’ve been wanting to do this to you all night long.” With that she pushed one end of the two-foot long dildo into her pussy, then crawled between my wife’s legs to bury the other end in her cunt. She then lay flat on top of her, and the two women started humping each other wildly, moaning and kissing at the same time. They quickly worked themselves into a frenzy, which ended with both of them coming explosively.

When the party ended, Sam and Lily told us that everyone was happy that we had come, and that they hoped we would be back. I told them I was pretty sure they could count on that.
