I had been for a night out with my best friend, his wife and a few mutual friends. Me and my friend's wife had always gotten on quite well and there was some occasional flirting, but it never lead anywhere. She has always had a somewhat curvy figure, which include a fantastic pair of huge tits. At the end of the night out everyone headed home and I went back to my friend and his wife's place (I live out of town so couldn't drive until I had sobered up). By the end of the night my friend was so drunk he went straight to bed while his wife and I stayed up for a bit longer.

After chatting for a few minutes she then went upstairs to check on my friend. I got ready to sleep on the sofa so stripped off and got under a blanket. Just as I was starting to fall to sleep my friend's wife came back down stairs. When she came into the lounge she sat on the sofa with me while I was still laying down. I don't know why but she suddenly started kissing me and after slight hesitation I kissed her back. Next thing I know she is playing with my cock with I'm fondling her tits. Between us we have a sobering moment and agree that we shouldn't keep going.

The next morning my friend got up first because he had a football game. When he got up we chatted for a few minutes and then he left. Within a few minutes of him leaving his wife came downstairs wearing a dressing gown. She sat at the end of the sofa by my feet and we started chatting. Before long her hand is moving slowly up my leg and she starts rubbing cock over my underwear. She the took my cock out and started jerking it slowly. Knowing she was my friend's wife had my so turned on I was rock hard, however at the same time I could help feel a sense of guilt.

She then said, "I really want you to fuck me". Suddenly guilt was no longer an issue and I went for it. When I took her dressing gown off she was completely naked underneath (she knew exactly what she wanted when she came downstairs). I laid her down and the sofa and buried my cock deep in her pussy. She was so wet and tight I felt like I could cum straight away, but managed to hold off for the time being.

While I was fucking her she kept telling me how big my cock was and how great a fuck it was. She got even louder when I started smacking her ass.

After fucking for about 10 minutes I realised I was not going to last much longer and she started begging me to cum inside her. I told her I just had to cum all over her tits, so she laid on her back and started jerking my cock as quickly as she could. In know time at all my cock was bolting several heavy shots of cum. Her tits glistened with my cum all over them.

I know it's not right to fuck my friend's wife, but the fact I shouldn't have done it is what made it so hot. Since then I keep checking out my others mates wives and girlfriends and fantasising about fucking them.
