Pleasure pissing

Bike runs over a few days, camping in the bush. I was the only female at these gatherings, but was treated as one of the boys. One guy, was constantly drinking, like me. Everywhere we stopped, he would have a piss. I followed him one day, and stood behind him as he pissed, rubbing my hand down his body. That progressed into me holding his cock for him while he pissed. That progressed into me giving him a handjob, while he pissed. We soon found out that he could piss, while hard, and then cum straight away. This was over months, years. We just kept going up a notch of things we could do. In the end, when he needed, I would go to his house. Just friends, it was our normal. One day, I stripped his clothes off. He took off mine, leaving me with a white singlet on. He pushed me into the bathroom, forcefully. I liked the new game, I didn't know what was going to happen. He grabbed me and kissed me hard, spat on me, and put his hand around my throat. Pushing me to my knees, he fucked my face, really pulling my hair. It hurt, but it turned me on just as much. He stood me up and turned me around. He tied my hands behind my back. Blindfolded, he sat me on the loo, and I started to give him a gentle headjob. His hand on my head, the other around my neck. I cum, and because I did, he swore at me. Calling me the slut I was. I'd never seen him turn like this. So he continued guiding my head on his cock. It was rock hard. I knew he was close to cumming. With my legs spread, he roughly fingered my cunt. I was so wet after cumming, and not knowing what was coming just got me even wetter. He held my head, cock as far as I could take it. He started to piss in my mouth. He told me not to move. I couldn't. I had to swallow it all. I coughed and choked a few times, but I never spilt a drop. Fuck yes I enjoyed it. I enjoyed being over powered. He took his cock out of my mouth. I could feel my shirt getting wet, I could smell piss. He was just standing there laughing. He told me to open my Mouth, and would piss on my body and in my mouth. With my hands still tied behind me, I heard him wanking. I knew what would be coming next, so I held my mouth open. He grabbed my head again and told me not to spill a drop, and to swallow it all. As he cum, he really moaned so loud. As he finished, I was so desperate for him to fuck me. But no...we jumped in the shower and he washed me, still tied up. This was our fun. We never fucked.
