A few years ago, we let my wife's friend stay with us. She was with us for about two years. She drove me wild because I thought she was really hot, always in some state of undress, and always masturbating.

Well one night I was in bed alone and I was sleeping naked. I woke up to someone behind me. I felt bare breast on my back and I had a hand jerking me off. I was already hard. At first, I thought it was my wife. I rolled on my back and they moved down and started sucking me. They weren't at it very long before she got up and straddled me. Then they put my cock in their pussy and began to fuck me. I was felling their tits when I finally realized something was wrong. I was finally getting completely awake and realized it wasn't my wife, but her friend.

For a few minutes, I just went with it as it was really nice and hot. Then I warned her I was about to cum and she didn't say anything. She just kept going and I held her hips as I came in her. Even after I finished cumming, she kept going. I tried to talk to her but she never responded. Then I realized, she was doing this in her sleep.

I got her off me and got her to bed. I tried to apologize in the morning, but she didn't remember any of it and even denied it. I made sure nothing happened between us again and later confessed it to my wife.
