I was a kid and learning to ride horses. My mother thought that was a good idea. At the stables we had lessons in the paddock, but once in a while we went out for rides along the trails. That day we left, just me and Rob, for a ride along the trail. I got the urge to pee and held it in as long as I could and until I had to ask Rob to stop and let me pee in the bushes. Rob held me tight against him, made me pee in my pants and all over him. He held me tight by my butt and kissed me hard on the mouth and promised to pee on me.
It was the beginning. I peed on Rob after that, held onto his neck, my legs wrapped around him, and I just peed away in my pants and all over him. He kissed me and felt up my butt and grabbed my still baby girl titties. He pulled out his pipi and I opened my mouth and he peed in my mouth and I sucked his pipi. Since we played pee I kept a change of clothes at the stable and he did the same and we showered together where they washed down the horses. He had a big pipi for a girl my age and I had a itty bitty pretty pussy. I rubbed myself against his hard pipi and he grabbed me hard by my butt cheeks.
I was a good rider and advanced to the precision team and all that and my mother was happy at my progress. She didn't know that Rob fucked me and I sucked his pipi, that Rob peed in my mouth and my face and I peed on him. But that was between me and Rob and not my mother. It's a 'fetish' that I've never grown out of.
