I have been fascinated with the idea of this for years but couldn't quite come to terms with it. Then I started dating a girl who could squirt. That was an eye opener. I started checking out GS porn, despite that she would squirt on me and I would drink it, she was against me drinking her pee, or doing anything with it.
Move on, we break up get into a Long term with another girl and she is open to most things but I am embarrassed to ask. We do lots of kinky stuff, but i started putting water inside her with a turkey baster and she would then shoot it into my mouth. We did this but I still wasn't comfortable asking her to pee on me. Eventually one day we were messing around and putting water inside of her and I said piss it out onto me. She stopped and replied there is a difference, did I want her to contract and squirt water out or did I want her to pee in my mouth. I said to pee.
It wasn't a good idea.
It was really strong, and it took my breath away, to the point it stung.
But I was still interested in it. We talked about it and the next time she drank a lot of water and had a diet soda, and she peed on me again it was completely different. We are still together and though she doesn't love it she does indulge me with some regularity, she doesn't like the setup eat clean, lots of towels and what not but when we do its great.
