Andy and i had been to the pub and called back at our house for a night cap. Helen was still up and in her dressing gown. Andy had been fucking her for a while but he had no idea i knew. we sat and chatted for a while and i told him that i had got a porn video if he wanted to take it and watch. Helen suggested we play it now. i was a bit surprised at that but I didn't need to be told twice. i put it on and sat next to them on the settee, Helen in between us. we started watching it and i put my hand on Helen's leg, her dressing gown moved showing her legs. Andy looked and smiled. I got up to go to the loo but left the door open a bit. i stopped and watched he moved over to her and they started kissing. this was the first time i had seen my wife kiss another man like that. It was so horny. she was snogging him like crazy. he put his hand under her dressing gown and was rubbing her pussy through her knickers. she was rubbing his cock through his jeans. I watched for a while then went to the loo and returned. as I walked in they moved apart.I sat down and put my hand under her dressing gown she was very wet. Andy got up and went to the loo, he had quite a bulge in his pants. when he had left I kissed Helen and pushed a couple of fingers in her. I asked her if she would like us both to fuck her she said she would, i told her that when Andy came back I would go to the kitchen and she could tell him that I knew he had been fucking her. I went to the kitchen and Andy came back in the room, Helen's dressing gown was open showing her legs and knickers. I heard her talking to him and then they both got up and left the room. I waited a while and went back in. they had gone to the bedroom. i walked in and they were standing there kissing she was trying to undo his pants to get to his cock. he looked at me not knowing what he should do, Helen just continued to undo his pants and started kissing him again. I got behind her and undid the belt on her dressing gown and slipped it off. all she had on was her knickers. Andy stepped out of his pants and she was rubbing his cock. I was kissing her neck and rubbing her boobs. Andy had his hands on her ass pulling her to him. she was snogging him like mad and pulling at his boxers. she got them down he took his top of and was naked. They got on top the bed and i stripped off I joined them on the bed. he was rubbing her pussy through her knickers and she was slowly wanking him. I pulled her knicker to one side for him so he could get right to her hole. My heart was pounding. she started kissing me and playing with my cock as well. Andy and I took her knickers off and both started rubbing her. she had her legs open and was so so wet. we were sucking her tits and biting her nipples. she was pulling my cock towards her so I got on top of her and started rubbing my cock on her slit. she was pulling me towards her and i slip my hard cock slowly in her. It was strange having someone watching. as i was fucking her she was playing with Andy's cock, i could see pre cum on his cock and I thought he was going to cum. I pulled out and lay next to her. He got straight on top of her and started fucking her fast. He was kissing her and squeezing her tits, moaning. Helen had her legs round him and was fucking him back. she started to shake and I knew she was cumming, he gave one last push and started to cum in her. I couldn't believe what I was watching, there was my young wife being fucked by our friend. they lay there for a bit kissing and he got off. I got straight between her legs and could see his cum in her cunt. I rubbed my cock in it and slipped in her she was so wet and her hole felt big. I started to fuck her faster and faster while she was kissing Andy. I could feel her start to cum and I exploded in her my ball were aching. I lay there until I softened and rolled off. She was wanking Andy who was starting to harden, I was rubbing her pussy and fingering her it felt so sticky with 2 loads in her along with her own. I felt Andy's hand on her pussy and we both started to finger her. She was fucking our fingers like mad. I took mine out and sat up to watch them. They were kissing and touching each other, it was so horny to watch. Andy was hard by now and Helen got on top of him, she lowered herself on his cock and slowly slid down it. She put her hands on his chest and moved up and down his shaft. Andy was playing with her tits and nipples. I was wanking as I watched her fuck him. She leaned forward to kiss him and I watched his cock slipping in and out of her pussy covered in our spunk. I got behind them and started rubbing her ass rubbing some of her juice and our cum over it. i slipped a finger in her pussy and could feel his cock in her. I pulled it out and started rubbing her ass. I got the tip of my finger in her and she started to push back. I pushed a bit harder and got it all in I could feel Andy's cock fucking her as she was fucking his cock and now my finger, It wasn't long before they both cum. As she got off him I got behind her and fucked her doggy style it was so sloppy I added a bit more and we all lay there for a bit before Andy got cleaned up. Helen just put her knickers on. As Andy was leaving she snogged him and put his hand on her pussy and smile. She asked him if her had enjoyed it, he smiled and said yes. She told him that was good and would he like to do it again. He told her that would be great kissed her and left. She took me by the hand to the bedroom and got on the bed and took her knickers off, opened her legs and asked me if I wanted to look at her full pussy. I got between her legs and she opened her lips, I could see both our cum in her dripping out. I started rubbing and fingering her till she cum again. I asked her what Andy had said when she told him that I knew he had been fucking her. she said that he had gone white, but she told him that it was my idea in the first place and that it was OK with it. then when she asked hi if he would like to fuck her there and then he couldn't believe his luck. She said that she stood up took him by the hand and led him to the bedroom. He's now been fucking her for over 29 years and still going strong lasted longer than his 3 marriages. Lots more to tell.
