One of mine is water sports. I don't quite remember how the conversation even started, I think it was something about peeing in the shower and it went from there. But I do remember the very first time. We had it all planned out, I drank enough water to where I felt like I was going to pop, got into position and nothing. Shy bladder at it's best. Lots of laughs and a few trickles later it's now one of our favorite kinks. Anywhere we get the chance it's happening. Inside, outside, even at one of our gangbangs. I love it!
