My 2nd Ex and I used to go to house parties for BBWs every month. The women who were regulars became friends.So, the September party was for a woman named Margaret's birthday. It was on a Saturday, and I had to be at the store later than I expected, and my Ex was going to help decorate Judy's house for the party, so she went early. When I got there, the girls were sitting in the living room having cake. There was one other guy there, only wearing a towel, also having cake and something to drink, but I didn't see my Ex. I asked if she was still there, and Laura said "She's around here somewhere. have you tried the kitchen?" I went to the kitchen, no one was there. I went to the office, no one was there. The door to the back bed room was closed, so I opened it a crack ... The bed faces the door, so I saw my wife from behind riding some guy's cock, cowgirl. My eyes focused first on her back moving up and down, and then on her butt sliding, bouncing, up and down this guy's cock. She was telling the guy "Your cock feels good, I'm cumming all over you." And I focused on his balls, which were coated with her cream.
So, I closed the door, and went back to the living room. Margaret, the birthday girl, was getting her pussy eaten, and the other women were watching and making comments. Judy asked me if I found my Ex. I said yes, and she asked me where she was. I told Judy that she was in the back bed room. Judy was like, "Still? She's been at it for hours and hasn't come up for air. Tell her to get her ass over here and have a piece of cake!"
