This one I do enjoy, and it actually goes pretty far back. Grew up having a pool, and we were taught never to pee in the pool. Would get out, pull our suits aside and pee behind the pool. Soon we would watch to see who could pee the farthest. One time while older I dated a girl who said that she could pee further than anyone, and one night while we were skinny dipping with another couple, we all got out and peed next to each other. Already nude, no one cared, and my gf actually did pee pretty damn far!
Later in life, with other partners, we would pee on each other in the shower, and always loved watching a girl pee. I was always turned on by it. Then I met a girl who was pretty damn kinky.
She is very much in to watersports and adores being peed on and pee play. I have posts of her on my page, she is old gf.
One night after one of her amazing blow jobs, I said that I had to get up to pee, and then clean up. She just bent down on my cock and said to go ahead and pee. I said absolutely. It took a little bit to get over the stage fright and finally let go. She swallowed every drop, and fingered herself to another orgasm. She sucked me hard again and she turned around and I fucked her from behind, and just before I came, she turned around and I came in her mouth... we still chat but damn I do miss her kinkiness!
