I recently saw my wife's ex, naked, at the gym. I was shocked at how well endowed he was. When I asked her about, it she laughed and said, "Oh my God, I know! He's totally huge." For some reason, I was turned on and we had some of our best sex ever. This continued for weeks and she has asked me if I'd like to watch them together. She said she'd love to do it if I was into it. I have a big decision to make.
