Years ago I took my then girlfriend Holly who I had been dating for about 6 months to my best friend's house party. We got there and had a few drinks, danced and generally had a good time. Then at about 2am everyone either passed out or went to bed in various rooms around the house. Me and my girlfriend were going to sleep downstairs in the lounge on the sofas. We started to make out on the sofa and I went down on her and we were going to fuck but unfortunately I couldn't get it up no matter what I tried, which she was a bit annoyed about. I asked her if she wanted me to go down on her again but she said no and went to sleep.
Anyway I fell asleep shortly after but when I woke up a while later I noticed she wasn't in the room anymore. I thought maybe she had gone to use the toilet or gone to the kitchen to get a drink. I didn't really think anything of it and went upstairs to use the toilet and see if I could find her. As I was walking towards the bathroom however I could hear the sounds of people fucking coming from one of the bedrooms. As I got closer I saw that the door was open slightly so I snuck a peek through and there was my girlfriend totally naked riding some random guy on the bed!
I watched as she bounced up and down on his cock which must have been hitting the right spot as she was trying very hard to stifle her moans so not to wake people but I could hear her moaning "oh fuck it feels so good" I'd never seen her like this or make nosies like it with me but instead of being angry I felt so turned on and noticed my cock was rock hard! I watched her riding and started playing with myself stroking my cock with two fingers as she came but continued to ride him, I came fast and went into the bathroom to clean myself up. To this day I still have the image of her riding him burnt into my memory, her ass cheeks bouncing as she rode that big cock.
Everytime we had sex after that all I could think of was her riding that guy and it made me cum so quickly. She broke up with me about a month after that on the phone while being fucked by another guy.
FUCK MY WIFE!
