Em and I had always had a very active sex life. We fucked a lot, even a dozen years into our marriage, and never shied from exchanging fantasies. We also engaged in a little light BDSM from time to time. One time, well past our 10th anniversary, while she was riding on top of me, I reached up with my left hand and squeezed her throat. Gently at first, but then harder, tighter. She moaned and quivered as she came on top of me. From then on, this "love choke" became a go-to move. It never failed to make her come.
Compared to others who've been married as long, I think our sex was outstanding—we could share thoughts and fantasies freely. At some point, we started talking about threesomes, foursomes, and swapping partners. We were up for anything, including me with another man, her with another woman, whatever. We were both non-judgmental of whatever the other one wanted—one of many signs that we are so well suited to each other sexually.
Em had a very sexually adventurous friend we often fantasized about, but after sex, she would mention that she could never actually do anything with her friend, that she would prefer a stranger if it ever came to that. I on the other hand preferred to think of a real person, or real people. But honestly, whatever heightened the fantasy for each of us was fine with me.
Last summer we took a trip to southern France. For one week we were free to be lovers again, not parents or "domestic life partners." Each day we explored our shared passions, unfettered by the distractions of day to day life at home. We went to a nude beach, fucked hard on the balcony of our hotel, fucked on a deserted street while walking home from dinner, and generally reinvigorated the sexual energy that made our match so great.
As the trip was nearing its end, we spent our last night in an airport hotel next to Charles de Gaulle. It was a nice place, with a spa. We wondered down to the spa and were pleased to find no one else there. After soaking in the steam room, nude of course, we adjourned to the hallway outside the steam room, where I fucked her hard from behind while pulling her wrists back, wheelbarrow-style. We came simultaneously, as we often did, and then embraced sweetly afterward, as we often did. In a relatively new twist, I had started occasionally "cleaning her up" after sex; sometime on my own accord, sometime at her urging. This time, with some wine in me, I had no problem going down and licking my cum out of her pussy. It wasn't something I thought I would like, but, as I said, I'm up for just about anything that keeps our sex exciting. I didn't mind it, and she seemed to enjoy it.
After I cleaned her up we showered, which helped to wake me up a little, so we decided to go back into the steam room for another few minutes. We did not realize that while we had been in the shower, the steam room was no longer empty. We opened the door, naked of course, and found another couple had gone in for a steam. The woman was lying on her back, naked, on top of her towel. She had what I would call bouncy blond hair, past the shoulders, perky breasts, long legs, and a little runway strip of light brown pubic hair. The man, also naked, was sitting spread eagle on his towel. He had black wavy hair, was in good shape, and his thick cock was resting on his balls; he was also well-groomed. They both appeared to be in their early to mid 30s.
We were surprised to see them, and they us. "Bonjour," the man said with a grin. Then he asked us something in French. "Non parlez Francais," I said, and he shrugged his shoulders the way the French do, as if to say "No problem, whatever." The woman was just grinning slyly at us as she lay on her back.
My wife is not usually given to modesty but it's not every day you walk naked into a small steam room to see another naked couple staring at you. Instinctively, she covered her breasts with her hands, but quickly realized the futility of that effort. She is well endowed—voluptuous—with feminine hips and a thin triangle of dark brown pubic hair between her legs. We took our places on the other side of the small room, she lying on her back, like the other woman, I sitting on the bench below her. The other couple was no more than 6 feet away.
There was a brief awkward silence before the French couple started talking under their breath to each other. At this point the woman began rubbing her breasts slowly and squeezing her nipples gently to get them hard. Mission accomplished. I glanced up at Em and we grinned at each other. She then did the same thing. At this point I looked down to see "Francois" stroking his cock. They were looking at each other and chatting/giggling in French. He looked over at me and looked at my cock, which was growing, and said something which I interpreted as "Your turn." So I started stroking my cock as well.
Francois then got up and walked over to his lady friend, who sat up and took his cock in her mouth. At this he looked at us. Em and my eyes locked, I raised an eyebrow, she nodded enthusiastically, and it was on. We mimicked the other couple. As Em sucked my cock I rubbed her breast and pinched her nipple. Shes huddered a bit and made a little moan. Francois appeared to like this and kind of chuckled as he looked at us.
He was grinning as he looked at us and asked me a question in French, which I took to be "This is pretty good, eh?" I answered back "Oui. This is awesome." But apparently that wasn't his question, because he looked down at his lady and said something, then pulled his cock out of her mouth and walked over towards us. Em was still sucking me but slowed down as she watched him move our way. His cock was hard, probably 8 inches long and plenty thick, and was bobbing back and forth as he walked.
He got over to us and said something and made a "switch" gesture with his hands—so it now became obvious that what he had asked me was "Do you want to switch partners?" And I had said "Oui." I looked down at Em and asked if she was ok with it, and she said she was if I was. Our moment of truth had arrived. We had talked during sex many times about being with other people, but neither of us thought it would actually happen. Now, I leaned down to give her a kiss before she started sucking another man's cock.
Our eyes and tongues met simultaneously—with Francois' cock standing inches away. It was as close as I had ever been to another man's cock, and I couldn't resist touching it. I took it in my left hand and with my right I guided Em's head forward so she could take it in her mouth. It was an incredible turn-on to watch my beautiful, sex-loving wife suck this man's large cock. I just knelt there for a second watching. She went at it vigorously, with her mouth and her right hand. He moaned in pleasure and said something in French.
She was looking at me as she sucked. I can't imagine what the look on my face was like. After about ten seconds, I licked my lips a little and she pulled her mouth off and said, "You want to try a little?" I didn't say anything but moved forward ever so slightly, and now the tables turned and her left hand went to the back of my head and guided me onto his cock, which she held in her right. I had sucked one of her dildos during previous sessions of ours, so I had a general idea what to do, but the real thing was very different. It was warm, and wet with her saliva, and big. He muttered something again, and Em whispered to me, "That is so fucking hot." She kept her hand on the back of my hand, and was gently pushing it as I moved back and forth on his cock, which only heightened the excitement because it added an element of force and control—as if she were making me do this. I grabbed his cock with my right hand and stroked it as I sucked. I couldn't take his full length but went as close to the base as I could; stroking it with my hand helped a bit. Then she took her hand off the back of my head and moved her mouth towards the confluence of my mouth and his cock, and said "OK, honey, I think our other friend is getting lonely over there." I stopped sucking/stroking and said, "Oh, right, I completely forgot about her. She needs some TLC as well." But Em surprised me when she said, "You stay here. I'll help her out."
This was certainly a little different than I had envisioned our first foursome to go. Em walked over to "Marie", who had been rubbing her clit pretty furiously watching our little suckfest, and knelt down between her legs and proceeded to lick her pussy as if she were an experienced pro. Francois and I were watching with rapt attention as my wife licked and then fingered his partner's pussy, to her obvious and audible delight. Marie went from zero to 60 in about 5.3 seconds, moaning and rubbing her tits and squeezing her nipples the way Em liked to do when I ate her out. I was just kneeling there, holding Francois' cock in my hand while we enjoyed the show our ladies were putting on. But soon I felt a little slap on my cheek, which stunned me, and looked up at Francois, who said something and pointed at his softening cock. But watching the ladies in action let me know I had had enough of cock-sucking for one day, so I got up and said to him as I did, "I think we need to re-focus our activities over there," pointing to our beautiful partners.
