It started off as just talk for us, then watching it on pornos. We implemented it into our fucking sessions. I thought she was just talking to turn me on untim we had a sitter one night and got a hotel, and shortly after our arrival there was a knock in the door. It was her ex fuck buddy that she always talked about during sex. I found out that night she wasn't saying he had a big dick (which I told her I wanted to see her get fucked by a big dick) but he actually had a really big dick. That was the start of 20 years of playing.
Ultimately all girls want to try it at least once, most are afraid of how they will be perceived after the fact
