Always found myself incredibly turned on by the thought of watching another couple have sex close up. I've checked a few websites and finally got up the courage to visit a site this week. I drove up to the Wisley site and parked up next to a couple in a car. So horny, but equally hesitant, they smiled at me and I smiled back. I spent a bit of time looking at my phone, trying to decide what to do when I noticed a guy from another car wander over to them. The lady was in the passenger seat and had the door open while the new guy casually chatted with her and her husband. After a couple of minutes I noticed she had extended her leg put of the car door and the new guy was leaning in. I moved in my seat and I could see that he had his finger on her pussy and was gently rubbing. She pushed back on her seat and we made eye contact again. This time we both held it and, to my absolute surprise, she gestured to me to come over. I was so hard and so apprehensive when I got out of the car and walked across. I stood next to the open car door with my cock throbbing in my suit trousers. While I stood, midtrance, another older guy walked over. He obviously wasn't welcome as her husband gave him a stern 'no thanks'. At this point she asked if we would like to join them in the woods. As nervous as I was I wanted to watch, so I eagerly agreed. The four of us walked as casually as we could to the woods and, once we'd been led to a quiet and secluded area, the couple proceeded to put down a huge towel. The husband got his cock out and she hungrily started to suck him. She eased off her top and pulled her bra off to reveal beautiful large breasts. The biggest I'd seen up close. She was playing with her nipples while she sucked him. The other new guy was rubbing his cock in front of them. The lady stopped sucking her husband and started gently stroking him. She looked at me again, and said words to the effect of, get your cock out too. I was happy just to watch, but her comment was taken like an order and I pulled my hard cock out of my trousers. I'm not a small guy and she seemed pleased with me. Her husband commented about my size and asked if I would like to fuck her. I looked at the lady and she said she would love to. She rummaged in her handbag and brought out one of several condoms and proceeded to unwrap it thrn push it on my eager cock. She then got onto all fours and said, and I kid you not, 'fuck me like an animal'. Well my cock was straining and any doubts I had were a distant thought, as I kneeled behind her and started to enter her. I usually have to go very slow, due to my size, but I said inside her in an instant. We were both surprised by this and at that point we fucked as hard and as frantically as I ever had in my life. She took my cock in all the way and on every thrust, I could hear her breasts slap on her belly. The new guy had his cock in her mouth as her husband watched and wanked. Every now and then she would break off from sucking him to let out a moan. Then she started rubbing herself, and me, really hard. After a couple of minutes she was shaking and gasping; at this point I was nearing my come too. I pushed in so hard as I felt my release and she pushed against me so hard she was sat on my knee. As I slid out and took the condom off she rummaged again into the bag and handed my a couple of wet wipes. She gently admonished me by saying I should have finished off on her tits. I didn't realise before as last just took over me. Post come, the nervous feelings came back. I said an awkward thanks to the couple and as I walked off, I looked back to see her sucking her husband and wanking off the other guy again. There were a couple of other people nearby who I hadn't noticed who had obviously been watching and wanking, and they nodded an uneasy acknowledgement. I got back to my car, started the engine and drove off in a bit of a daze. I couldn't have imagined the evening taking such a turn despite all I had read in advance. I drummed the wheel and smiled a smile knowing I'd fucked a complete stranger. So hot..
