I had wanted to try threesome for a while but my girlfriend wasn't overly keen. After months of pestering we discussed it and decided that only a two guy threesome would work, as she didn't want to see me with another girl. This was fine by me as i wanted to see her get fucked by another guy anyway. So one friday we were out in our local, socialising as usual with the usual faces. There was a young lad in there who was a regular and was barely 18, we by the way were 20. Anyway towards the end of the night my girl started flirting with him and I could see a twinkle in her eye. I let her continue, she sat on his lap and stuck her tongue down his throat and I knew tonight would be the night! She writhed on his groin and suggested we all leave together. It was a short walk home so not much was said. we got in and pretty much got down to it!!! Clothes strewn on the floor. Straight on the bed with her getting off with the lad and my face buried in her pussy. after a while i look up to see my girl taking the lad in her mouth and sucking him hard!! I couldn't wait and parted my girls legs and fucked her hard! I gave her a pounding till i felt like i was gonna cum and switched. i sat and watched the lad mount my girl and slam his rock hard cock into her sopping wet pussy. It was great watching him pummel her and for her to wrap her legs around his back dragging him deeper. I moved to the back so i could watch his cok penetrate her pussy and the site was amazing. My girl then got him to lie down and she rode him good and hard, again i watched her move up and down on his cock as it dissappeared up her. Feeling horny as hell I thought I try my luck for a double penetration. I got my girl to give a saliva fest blowjob (without teling her why) Then I moved and poked her tight arsehole with my cock, she turned round and asked me "what I was doing" and I replied, "this" as I managed to inch my helmet into her tight bum hole. At the point disarter, she asked me to stop and not to do anal on her. So after cleaning my cock I got her to suck the lad off while I did her doggy and boy was it a great site. Then we swapped again and she lay there and let the lad shag her sideways whilst sucking me off. She looked deep into my eyes as she sucked and i cold feel myself coming, I shot a hot load down her throat which she took graciously. meanwhile we hadn't noticed our friend start moaning heavily and cumming right up her. we went to bed after, all three of us. Then in the middle of the night I woke to hear noises from the front room, i strolled in to find my girl and the lad fucking on the setee in reverse cowboy position. I felt a little miffed at not bein invited but then to my horror I knelt to see the action and what did i see............................... My girls pussy wide open and running with juices and a little lower, this lads cock right up her bumhole, no rubber or anything, the thing I got denied earlier. Are you gonna join in then? she said almost sarcastically. I thought, fuck this so i did. I fucked her as hard and as mean as i could, how dare she humiliate me like this. She was practically growlong now as I drilled hard in the pussy while she rode this kid. I turned to see our reflection in the telly and the sight two cocks up my girl simultaneously set me off as I spurted up her moist pussy. Seeing the lad hadn't cum yet I preceded to watch him pummel her bumhole in doggy style position with her moaning like a slut. I got a real close look as i watched slip in and out and wondered how he got her to allow him in. Then I heard my girl moan as she climaxed and squirted juices down her leg, the spasms and clenching must of set our friend off as he then dumped a load up her bumhole, leaving his com to trickle out and mingle with mine in her pussy. in the moning he left and i thought about what had happened. The bitch never told me how he got her to do it but I still can't get it in that sacred hole even now. So far it has been a one off and I would love to get in the mood for more.
