Yes, with her first boyfriend and the biggest cock she'd ever had. It was at a club. She told me he was at a nearby table with a group of friends. I was curious to see how big it was, so I watched him discreetly. When he went to the bathroom, I took the opportunity to follow him. I wanted to see how big his cock was. Unfortunately, the urinal next to him was occupied, so I couldn't get a good look at his tool. But the thought of it turned me on, and that night while we were having sex, I told my wife. She smiled at my crazy ideas, and even though she didn't say anything, I know it turned her on.
