My best friend has a very active sex life and loves to tell me all about it when we are out. She's 28 and has had more sex than I have and I'm 45 which I find frustrating in fact she regularly shares her adventures with you guys hence why I'm in here telling you my story. I have to admit I some times think of what she tells me when I'm having sex with my husband. I think its this frustration and worrying that I'm getting boring that stopped me from saying no to Paul. He's my husbands 'mate'. A few of us went to Turkey last year, to a villa with its own pool. In total there where 4 couples and we had a great time. 4 days into our two week holiday everyone was in the living room getting slowly plastered when I decided to jump in the pool. My husband, Paul and his wife joined us for a little while but as it was getting cold (about midnight) they jumped out leaving Paul and me alone. Paul is a nice enough guy, he's a bit full of himself and has always made it clear he fancied me, even his wife has had words with him about his flirting but my husband thinks its funny. Now I know some of you are going to criticise me for this but at the time it happened to quickly but I suppose I should have stopped him. Everyone else was talking and laughing in the living room which is about 12 ft or so from the pool, I was at the side watching when Paul got out and switched the pool lights out before jumping back in. I asked him why he had done that but he just moved in besides me. He said it was so they couldn't' see us. I asked him why he didn't want them to see us when he unclipped my top. I went to grab them but he pulled my top away and threw it into the centre of the pool. I told him to behave but he moved behind me and started to gently thrust himself against my backside. If id told him to stop he would have but I just found it funny and started to laugh. He slipped his hands round me and grabbed by breasts gently squeezing. I should have pushed him away, I mean I don't fancy him or anything and I love my husband but it was so naughty I just let him carry on. He was squeezing my nipples and kissing my neck which apparently my husband told him drives me wild. I though I would leave him carry on for a few more seconds and then push him away when one of his hands moved. He took my hand and placed it on his cock. I nearly giggled becouse it was quite thin and long but in a matter of seconds he had tugged at my bikini bottoms and I was naked. I whispered that we weren't going to fuck but he just said I could stop him whenever I wanted. And with that his thrust himself forward and his cock slipped into me. This was the first time I have ever had anal sex. He pressed himself against me and was fucking me as quickly as he could. One of the girls looked over becouse of the splashing and I told him he was making too much noise so he slowed down doing as deep into me as he could. I could feel his balls against my arse. Like I said, I should have stopped him and I could have but the feeling was amazing. With one hand he was playing with my tits and with the other his fingers where inside my pussy and all the time I was being fucked up the arse. We both watched the others hoping they didn't' come out, thankfully he didn't last long and within about a min or two I could feel hot cum shooting into me. I have to admit, I did cum and had to stay in the pool a few minuets to recover. Nothing happened for the rest of the holiday although he did try a few times. The most I did was give him a quick wank when we where in the pool but now I feel quite liberated and am wondering what I am missing.
