About a year ago, my 44 year old wife, who works in the airline industry, was sent out of town for two nights. We had long fantasized about her playing with another man, but she was always unsure she could do it because she was worried about the effect on our marriage. We discussed her upcoming travel and that seemed like a good opportunity to see if she could go through with it. I asked her to just go down to the hotel bar that first night and see if she could tempt a guy to buy her drinks and maybe eventually play with him if the chemistry was right. I asked her to keep me apprised of what was happening by text or calls as the evening progressed. Right around 8, she texted that she had finished dinner and had been in the bar about a half hour, but it was too early as only a few people were there and she was the only solo woman. She did say a couple of guys had certainly noticed her as they came into the bar. At least she knew she could attract men. Around 9 she called and said things had picked up, and an older man had taken a seat next to her and had bought her a drink. She rang off and said she would call back a bit later. I started to get excited wondering how this man was progressing in his flirtations with my wife. At the time I would have done anything to be across the room watching. I finally couldn't wait any longer and called her, but no answer. After a few minutes, I tried again and still no answer. I was lying in bed when my phone finally rang about a half hour later and I could hear a lot of background noise so knew she was still in the bar. She apologized for not answering as things in the bar had picked up and she hadn't heard her phone. I asked her what was going on - was she still with that guy from earlier? Right off I could tell she had had a few drinks. She said the first guy had bought her a second drink, then wanted to get a table for dinner. He had invited her to join him, but she politely declined - no chemistry. Soon after, two guys walked in with a woman. They were across the bar and after a little while she had made eye contact a few times with one of the guys and before long they had waved her over to join them. They also worked in the airline industry. Asking if she was having fun, she said "Yes, very much!" I asked if she was getting friendly with one of the guys. Again she said "Yes", and that the one guy was giving her lots of attention. I asked in what way, and she said he has been pretty 'handsy' with her and had been touching her a lot. I asked her to tell me more and she said he had put his hand on her leg a few times moving the hem of her skirt up her thighs, then putting his hand in between trying to get to her panties. I asked her if she was going to let him and she said she didn't know yet, but they had already kissed a couple of times in front of the other two, who not only didn't mind but encouraged them. She then asked if I really wanted her to let things continue and did I really want her to play all the way with him. "Do you want to?" I asked. "Yes," she said, "but only if it's really OK with you." By this time my cock was hard imagining her being with another man in bed, so I said, "Go as far as you want, but be ready for me to call in an hour or so to find out what's going on." With a tipsy giggle she said, "OK, I love you." "Love you too, baby," I said, "have fun!" The next hour was excruciating for me. What was going on? Would she answer when I called again, or would she be too busy getting laid? More than anything I wanted to hear all the details of what they were doing. My imagination was running wild and I was hornier than I could ever remember. Finally, I called and she answered. I could hear voices in the background and she sounded like she had had more to drink. "You doing OK?" I asked. She said she and her guy were doing just fine and the four of them were having a party in the other guy's room. It turned out the other guy and the woman were an item while her guy was the extra. Once in the room, they had split up into couples, with the other couple snogging on one of the beds, and she and her guy snogging on the sofa. She added she had let him take off her blouse and open her bra, and he had gotten her really hot from caressing her breasts and sucking her nipples. She asked me to call back in a little while as she and her guy were about to get on the other bed and 'play'. My cock twitched as the phone went dead. Again, my imagination ran away with me and I was so horny thinking about her being in bed with another man I wanted to wank my rock hard cock, but held off. I called back within 15 minutes and, when she finally answered, she didn't say anything and there were no party sounds. Then I heard her moaning with passion in the background like she was holding the phone away from her body. I asked her what was happening. There were a few seconds of silence, then another series of low passionate moans from her, and then she gasped, "Oh, yeah, like that!" Then silence, followed a few seconds later by some urgent passionate moaning from her. I asked again, "What's happening?" But all I got was more moaning, but at a much deeper and quicker pace. I kept listening and it was now obvious she had dropped the phone onto the bed next to her so she could use both hands for whatever they were doing. After a few more seconds of her moans of passion rising in volume and coming closer together, she suddenly gasped out, "Yes! Yes! YESSS!" Then I hear the unmistakable sounds of her climaxing. I immediately wondered, is she getting eaten out or is she getting fucked? My cock was rock hard and I was slowly wanking it to the sounds of her climaxing, but held off coming. Then there was silence except for the sound of her heavy breathing as she came down from what must have been an intense orgasm. At the same time, I could hear the couple on the other bed fucking loudly. It sounded like the woman was getting close to a climax, and then she screamed out her climax. God, it was so erotic to be listening - almost as good as being there. After about a minute or so, I heard my wife picking up the phone and I anxiously ask her what just happened with her. She said, still breathing still a bit out of breath, "He just went down on me and made me come with his fingers and mouth." I started to ask for more details, but she interrupted me and said very quickly, "Just listen on the phone. I can't talk right now. He's between my legs now and getting ready to put it in. I'm putting the phone down. Just listen!" There's silence except for the muted sound of bodies joining together, then a sudden gasp from her, then him asking if he's hurting her. She responded with, "No, it was more surprise. I didn't think you would go up me so quick in just a single push." He answered, "Sorry, but you were so wet from before and so hot, I couldn't hold back." Then I hear her start to moan intermittently as he starts to fuck her. Their fucking progressed quickly as the pace and urgency of her moaning indicated her passion was quickly building up. The muted sounds of their bodies moving against each other also increased in volume like they were being more energetic in their fucking. A little while later her moans became even more frequent and louder, just like she gets when we fuck and she's very close to coming. It was so real; I could almost see them together on the bed, him between her legs, her arms and legs wrapped tightly around him, and both of them moving their bodies earnestly against each other striving for release. Suddenly, he asked her if she was getting close and she said, "Yes. Don't talk. Keep going. Yes, just like that!" After a few more seconds, she gasped loudly two or three times as she started to come. Her loud gasps were so clear; I could almost imagine I was lying between her legs pumping her as she came. God, I wished it were me! Her gasps of release and completion lasted quite a long time until they became moans again, and finally became muted until the sound of her heavy breathing took over as she came down from her climax. But I hadn't heard him come, so I knew he was far from finished with her. Then there was the sound of them kissing and whispering to each other. Finally, she came on the phone and thanked me for letting her be with him. I ask the obvious question, "How was it?" And she replied, "It was fabulous, much better than I expected from someone I just met. I came so good and then we kissed and cuddled. Sorry to keep you waiting, but it felt so good I just had to enjoy the 'afterward'. But I'll make all this up to you when I get home. I think we'll be in bed a lot after I get back!" I then asked, "Does he know who you're talking to?" "Oh, yeah," she said, "I told him down in the bar of your hope I would meet a guy and perhaps spend some time in bed with him if the fit was right. He was more than happy to help and couldn't believe his luck!" As I listened to her reply, I could tell they were still playing with each other and I volunteered to let her go, but she told me she was going to leave the phone on the bed next to her so I could hear what was going to happen next as he was now between her legs and was starting to put his cock in again. There was a moan, then she gasped and said to me with some urgency, "He's back up me. Gotta go!" I heard the phone falling back onto the mattress and actually heard her wrapping her arms and legs around him again and saying to him, probably for my benefit, "Fuck me. Fuck me hard and fast. I want to scream when you come in me!" I listened for about 20 minutes to the squishing sound of him stroking his cock in her very wet pussy, then the build up toward a come with her moans, and finally her gasping and crying out her climax. He came just after her with male grunts of completion. It was so like being there and watching them fuck, I couldn't help myself and wanked to a tremendous come at the sounds of them coming. I sprayed cum all over my belly, then listened to them coming down, ending with them kissing and whispering 'sweet nothings' to each other. She finally came back on the phone and, answering my question how it felt, told me how wonderful it was to feel another man come in her. She also said how she should have done it when I first proposed it several years before. Then she again thanked me for being so understanding and letting her be with him. I was glad for her, then suddenly became extremely jealous, but I resisted telling her to get away from him. Instead, I reminded her she had to get up early for the next days meetings and she should get back to her own room. She hesitated, then said she was going to stay there for a while longer. I asked, "He wants to have you again, doesn't he? Or is it you who wants him again?" She hesitated again, then said in a low voice, "Yes and yes. We both want to do it again. I'm sorry, but please say I can stay and have him again. Don't be angry with me but I'm still so very horny, a lot more than I ever expected." I calmed down and told her I loved her and to go ahead and enjoy herself. She rang off telling me she would call when she got back to her own room. She rang an hour later, just after 1 in the morning, saying she was going to sleep - alone. Then she volunteered he had fucked her to another climax with her on top (and she actually used the word 'fuck', which she never used to say), then he had her from the rear on her hands and knees. And yes, he took her roughly from the rear, which I know she likes when she's particularly aroused. He came in her again after she had two quick orgasms, one right after the other. She then said she would call me the next day during one of the breaks and rang off. I again wanked to a climax imagining him violently fucking her from the rear like I do when I'm really horny. I was so turned on, it was very hard to fall asleep, so I wound up wanking a few more times over the next hour or so before finally falling asleep. I didn't hear from her the next day until after the last meeting ended around 4:30. She sounded strange on the phone and I asked what was wrong. She asked me not to be angry with her, but the four of them were going to dinner together, then go dancing in the hotel bar, and afterward all go the other guy's room and fuck as couples again, then probably swap partners. I pointed out to her that she used the 'F' word and she said she was using it deliberately with me since that's what this was, 'fucking' instead of 'love making', as there was no love involved. It was purely physical lust and didn't mean anything to our marriage or how she felt about me. She said she just needed to do it some more before coming back to me. I told her I understood - that as a man I had felt that way a few times in the past, but it seemed unusual for a woman to feel that way. Then she surprised me by saying she was starting to understand that men and women were not all that different when it came to physical lust. She promised to let me listen again, the same as the night before, if I wanted. Of course, I eagerly agreed, then told her I would love to be there with her if she did it in the future with another man. She said we would talk about that when she returned home, but she thought she would probably like that. That night, I listened to them do it for about an hour, then listened while she and the other guy went at it for another hour or so, and wanked myself to a come both times. Then she went back to her room to sleep since all the sex had finally worn her out. When she returned home the next afternoon, I met her at the airport and we went straight to bed. We lost count how many times we did it before morning, then groaned from lack of much sleep as we got up for work. We were both so turned on by what had happened to her during her two nights on travel, we had each other every night and then again in the morning for the next week or so. It really rejuvenated our sex life - not that it really needed it before. And yes, a few months later when she next went on travel, she had a similar experience, that time one-on-one with a man about 15 years younger than her who was a fellow attendee at her meetings, but whom she hadn't known previously. She told me later it was so erotic fucking a much younger man that she readily agreed when he wanted her with him all night, and the second night as well. Each night I listened for the first hour or so, then she rang off as he insisted on time alone with her as his price for allowing me to listen to them. She went on travel one more time after that and he was also an attendee, so they hooked up again. It looks like she may have a regular lover at those meetings in the future. She had not shown any interest in finding a local lover until about a month ago, when she slept with a colleague from another office a few hundred miles away who was in for a week long meeting she was also attending. After the second day's meeting, she went with him to his hotel room in the afternoon after the last meeting of the day and fucked him for an hour or so, then got home before me. When I arrived home, she appeared to be napping on our bed in just her panties. I smelled the odor of sex the moment I got close to the bed. She opened her eyes and beckoned me to lie next to her. When I did, she enveloped me in her arms and kissed me with some passion saying she had something to tell me. When I asked what it was, she suggested I get undressed. Sensing what she was about to tell me, I quickly got naked and returned to her arms. She quickly told me about her afternooner, ending that since I was not there to watch, she had brought home a souvenir for me, and told me to remove her panties to see it. By now my cock was rock hard with anticipation. I knew what I would find. She rolled from her side onto her back and raised her legs as I knelt below her hips. I slid her panties down and off, feeling the gusset soaked with slippery man cum as I sniffed them before tossing them aside. She then slowly spread her legs as she lowered them on each side of me as I knelt there. The pungent odor of sex hit me as I stared at her well used pussy, the hair around it smeared with cum. I immediately fingered her with two fingers, then added a third as I explored inside her still swollen pussy. It was a veritable swamp of cum. I groaned with lust and quickly removed my fingers, replacing them with my cock as I lowered myself onto her and plunged into her. I fucked her violently with tremendous lust. Afterward, she told me all about him fucking her just a few hours before. He was a young one and desperately wanted her to stay that evening, but she told him she had to go home so her husband could have 'sloppy seconds'. The next three afternoons I met them in his hotel bar and we went to his room where I watched him fuck her, and then had her in between their sessions which lasted several hours. Watching them and then having her myself in between was certainly as erotic and satisfying as I had imagined, and we intend to repeat it whenever and with whomever we can in the future.
