When Two Becomes 3 SeXStoRY

My Girlfriend and I have always had a good sex life, then things got a little stale, we decided a few months back that we were going to spice things up. We agreed that we would do something a little different at first we had thought about possibly swinging, but that idea didn't really appeal to either of us. We both really enjoyed the though of watching others and being watched. After a few days of discussing we decided that we would look for someone to come and watch us fuck. We put out an ad on a few sites, we after vetting all the responses we chose our guy to come and watch us. I booked a hotel room for all this to take place in, I don't really feel comfortable having strangers from over the internet into my home. One saturday evening, we decided to meet this guy in the lobby for a few drinks (just to calm any nerves). He was very pleasant, agreeable, 26 years of age. After a few drinks we decided to take it up stairs. We took a few drinks up with us just in case, more nerves kicked in but at this stage everyone was pleasantly relaxed. We entered the room, allowing her to walk to walk in first so I could drink in the view of her ass. She sat down on the edge of the bed, and patted it, I sat down beside her. He sat down on the other twin bed facing us. I think at that everyone was a little nervous, and jittery. After a few minutes of semi awkward, semi sexual small talk I remember saying "lets get this show on the road". This seemed to ease everyones nerves. My partner then turned to me and started kissing me, on my neck. A a guy this was kind of strange to me as usually I would do the neck kissing but, it was strangely arousing, I could feel the bl**d rushing to my penis and myself starting to get hard. I grabbed her close and kissed her passionately. I could feel her running her hands over my now rock hard cock which was almost painfully trapped in my jeans. I ran my hands across her breasts and slowly unbuttoned her top. Slowly I exposed her breasts, at this stage our watcher unzipped his trousers and started to touch himself (this was the first time that any other guy had seen my girlfriends breasts so it was kind a bit weird for me but I very quickly forgot about that.) She slowly at this stage had unzipped my jeans and was starting to slowly suck my rock hard cock. I could tell that our watcher was enjoying himself, the super charged sexual atmosphere seemed to amplify everything. He then asked me to massage my girlfriend. I didn't really even hesitate, I pushed her onto the bed and slowly took off her pants and panties and started to kiss her down her tummy and along her thighs. She was just lying there on the bed completely naked. I could tell that she was extremely aroused at this stage. I went to the bathroom to find something to use to massage her with. I was lucky to find a small bottle of baby oil in the bathroom which the hotel had provided. I went back into the room and turned her over so that she was lying on her stomach, I started to slowly pour oil all over her legs and lower back. I started to rub it into her legs making sure to run my fingers close to her pussy, in order to tease her. I then started to rub the oil on the top of her back. At this stage I couldn't take it any more I started to kiss the small of her back, and started rubbing my cock between her bum cheeks. I had pretty much forgotten that our watcher was there. I poured the rest of the oil on her making she was covered in oil and the slid myself deep inside her. I could feel her pussy wrap around my cock as I slowly slide myself in and out of her, while she laid there on her stomach. I could feel her starting to come and this naturally brought me closer to climax. I some how managed to edge myself so I didn't cum. It was at this stage that I noticed that, our watcher had completely stripped off and was standing at the edge of the bed, stroking his cock. He had positioned himself near my girlfriends face. I instinctively knew what he was looking for. Yet strangely i wasn't annoyed, usually I would be fuming, but I think the fact that I was so randy probably blurred my decision. She look at me over her shoulder, in a sort of 'should I ?' sort of way. I gave her a little nod of approval. I propped her up into the doggy position, and she slowly took his penis and started to suck it. I could tell he was delighted with himself, it was kind of actually arousing watching her suck on his hard cock while I pounded her from behind. It didn't take long before, I was close to climax. I could tell he was close too, I could very quickly feel the pressure building up for a massive release. Her pussy felt so tight. I couldn't help it and I shot a massive load deep into her pussy. We actually ended up coming together. I was still hard as a rock, but our watcher was close to cumming. I turned her over and entered her again. She had stopped sucking his cock at this stage and he was stroking his cock again. He then moaned "Im close". I looked at him and he at me then her, I pulled back and he crept up beside her and came on her body, slightly filling her belly button. I actually though this was pretty hot and decided to touch myself and stroke my cock as she lay there, after a minute or two I was ready to cum again. I pulled up to her and came all over her body and tits it was really hot... I think that is where I think I will leave it for now... More happened but I think thats for another time. I hope you guys enjoyed my experience as much as I did. Maybe I'll write again soon :)
