I did not get involved in pee drinking with my first wife. She was willing enough to go along with me watch her weeing but that was as far as it went.
My second never talked much about her previous relationships or sex life. I was used to long build ups with much foreplay, cunnilingus being a favourite but it was my hand which got her started. We had been going out together for about six months & as the time had passed she was more & more eager to make love & especially to take part in our long foreplay. It had just been a normal play time when it suddenly changed.
