I love when a guy pisses in me after he cums. It's one of my favorite feelings.
The best experience I had combined a few of my favorites. Anon guy from one of the apps came over and I was waiting naked on all fours, ass aimed at the door so that was what he saw when he walked in. I heard him say, "fuck yeah" and the sound of him unzipping. Within seconds, he leaned in and spit on my hole, his hands were on my hips and his cock was pressed against my ass. He didn't waste and time getting inside me in one fast stroke. Lucky I was kinda open already. He fucked me hard but didn't last long before he came, maybe 5 minutes.
But he didn't pull out. He stayed in deep and let out a sigh of relief as he started to fill me up with his piss. He held my hips tight so I couldn't pull away (not that I wanted to) and I swear the pissing lasted longer than the fuck. He kept up a satisfied moan as he kept going. I just remember how warm it felt and how full I was. "Thanks. I've had to take a piss since I left work. You're a good little urinal." And with that he zipped up and left. I never saw what her looked like, but I think about that one a lot. I hope to do all of that again just like that again.
