Stranger in a swing

I answered an ad in here a while back. A guy an anonymous fuck. He said he was face down ass up and lubed. I told him I was in my way. Before I got there he asked if I wanted to him face down or blindfolded in a swing. I told him the swing sounded like fun. When I got there he was in the swing with a blindfold in. I walked up and dropped my pants. I started rubbing his ass and worked a finger in while I was making myself hard. I slipped the head of my cock in and pushed it all the way in. I was pumping his ass and he was swinging back and forth his legs spread wide. My balls were slapping his ass as we fucked. After fucking him for about 10 minutes I was getting tired so I pulled and shoved my cock onto his mouth so he could suck it. He tried to pull away, but I held his head and wouldn’t let him stop until I was ready to cum. I pulled out and shot my load all over his face and chest. I pulled my pants back in and left. I heard him cussing me as I left, he wanted my cum in his ass. I told him next time I might.
