Got caught cheating in threesome [MFF] | 2016

I’m a little tipsy right now, and just thought I’d share this story.
Fake username, obvs

I went to a party at my wife’s work. I’m usually pretty nervous around new people, so I stuck close to wife most of the time.
She wanted me to mingle more though, so I started drinking a lot for the courage. I met two of her co-workers - two attractive middle-aged women.

We got talking, and I kept drinking more and more - they did too, but not as much. Eventually, they took me to the floor above, which was empty.

I was very, very drunk by this point, and could barely walk, so they told me to lay down on a desk that was there. All I remember after that was one of the co-workers was fucking me reverse-cowgirl-style, and I think the other was licking my balls.
It felt really good, so I didn’t do anything to stop it. I just stared as her fat ass pummeled me.

I then heard screaming and shouting - my wife had walked in on us. She pushed the women away from me and dragged me to the car. The next day, I begged her for forgiveness. She just said there was nothing to forgive.

So yeah, not that hot as I don’t remember all the details, but I still feel a lot of guilt about this, especially as I always find myself thinking about this event when I masturbate.
