We were in our early 40s and had been together for about 2 years we had a very active sex life as you do when first getting together.We started off fantasizing about introducing another person into our sex life, but it was always another man but she was a bit nervous.So one night after downing a bottle of red wine she agreed to a little adventure, so off upstairs she went and reappeared 15 mins later dressed to thrill low cut top (38 dd on view) skirt but no knickers on.Into the car we got a drove around looking for any males who she might fancy.After about 20 mins of driving around and her getting very wet we spotted a group of young men approx 18 to 22 years of age grouped together on a corner.I stopped the car up the road and off she shot straight up to the group. She apparently asked if anybody wanted to walk her home ,they could tell she had had a drink and also immediately 2 jumped up and wanted to.Both put their arms around her and wanted her to go with them but it appears they didn't want to share and she had to pick 1.She picked 1 and started walking along the main road with him, it was by now after midnight but still a lot of traffic about, as they walked along he started kissing her and immediately put his hand up her skirt and nearly cam in his pants when he discovered she was knickerless and had a black haired trimmed brush.He managed to walk along with his tongue down her throat for about another 30 yards till they found a public bench and he immediately went to work on her right ther in full view of the passing traffic, hand was straight up her skirt fingering her juicy fanny and groping her tits.Everyone passing could see her legs wide open and being fingered for about 20 mins while she had her hand on his prick which was rock hard wanking him in full view.She came in full view of everyone, but realised people were watching and made her excuses to leave he was gutted and wanted a fuck but she jumped back into the car and we left for home,I was so horny by then I wanted to fuck her in the car when I felt her pussy it was dripping, so rushed home and fucked her most of the night.Since then she has had other adventures and come home full up and dripping.
