I know many men have fantasies about their wife having threesome sex and with my wife and I it happened just the one memorable time. We were both in our forties, reasonably fit and healthy and had sometimes joked about getting her tits out for friends but nothing more than that. On this occiasion our mutual friend Pete had seperated from his wife of many years and was living in his brothers house whilst his brother was away working in Dubai. I was driving that night so my wife June could have a drink and relax. We arrived at Pete's place and he was not feeling too grand to go out so I went to the off license and got some wine and snacks to make a night of staying in listening to music and chatting. After a couple of hours I playfully pulled ny wifes dress strap down which she immediately pulled back up saying "no chance". Being a gallant gent I poured her more wine and we continued to chat, laugh and listen to good music. Once more I pulled her strap down and this time she left it off the sholder for a few minutes before pulling it back. Being a gent I poured her more wine. Another hour passed and she was a little tipsy and decided now was a good time to have a little dance and pulled me up to dance with her. As she swayed to the music she dropped her left strap, then her right continuing to dance. Slowly she swayed and then moved her arms through both straps, I thought "she's going to do it!" the straps came down and her small, firm breasts were there to be seen swaying as she danced. " If you want more" she said grinning mischeviously "you'll have to do it". I went around behind her and caressed her breasts, moving my hands down to her waist and pushing her dress to the floor along with her undies. There she stood totally naked only in her heels, swaying to the music. Our friend was mesmerised by this and just sat there open mouthed but not for long. He soon came over an took her breasts in his hands, stroking and kissing her nipples, moving his hands over her tight body which elicited groans of satisfaction from June. She pushed him back into his chair and leaned over him with her hands on each chair arm, her breasts were dangling over Pete with her legs on each side of his. Soon his hands slid down to her shaved slit and caressed it with more moans of pleasure coming from my wife. I saw Pete's hand move between her thighs and his thumb raise to gently enter her. June was moaning loudly now and enjoying every second of this attention. I thought I was going to pass out, hopefully before I had a heart attack! I moved behind her, dropped my pants and as Pete moved his hand away I entered her. Pete opened his pants and got out his very impressive dick, much bigger than mine it reached to his navel and impressively thick. June bent her head and took Pete's dick in her mouth while I worked away behind desperately thinking about my VAT return to stop myself cumming right away. I didn't last long though and came in gushes inside her beautiful smooth pussy. June then turned around and lowered herself slowly onto Pete's dick, easing it into her, groaning and swaying as she did. Eventually the full length was inside as she moved her hips back and forth riding Pete with happy noises coming from both ends. Grabbing my dick to suck it back to life which in the circumstances, didn't take very long she wanted more and as Pete pumped his saved up load into her, she got the same from me in her mouth. I was very proud of coming twice in a hour at my age. June spent the rest of the night until the early hours completely naked, servicing one or both of us as the mood took us, Anytime, we felt like it. One time I made coffees and came back to find her sucking Pete off, no problem it was that kind of night where we all understood it was something to be treasured with no recriminations or pestering in the future, It was what it was. Three adults enjoying a fun, no strings spontaneous happening. We never did it again. We had many threesome gropes in the car and blowjobs but the opportunity never seemed to happen again when everything was just right. Who knows what the future holds though.
