I was having a boring day at work so I was cruising Grindr and was hit up by a cute bottom guy. He was tall, about 6’1” with dark hair and fairly muscular but not totally ripped or anything. He asked if I wanted to fuck and I said yes but couldn’t go far from my work and I had to do it on my lunch break. I suggested the bath house because it was fairly close to me and he agreed. I also made sure he was good with fucking raw, and he said he loved it. We met at the bath house and I paid for both of us. We just got lockers so we went to the changing area and I got naked with just a towel and he stripped down to a jock strap and a harness. 
He had never been to the bath house before so we walked around, me with a towel around my waist and him in his jock and harness. Being the middle of the day, there was hardly anyone around. We briefly went through the maze, stopping to make out a bit, which got my cock growing. We went out onto the sun deck, and he put his towel down on one of the loungers and got on his ands and knees. I got behind him and knelt down, giving his hole a few licks with my tongue. I could tell he had cleaned out and was pre lubed. I stood up behind him and tossed my towel onto a lounger. It felt great being naked outside, although it was a bit chilly. I spit in my hand a couple times and between that and his pre lubing, I was able to sink my raw dick balls deep in him without any problem. I grabbed on to his harness and slow fucked him, sliding nearly all the way out before going in again. His ass was buttery smooth and felt amazing wrapped around my cock. This guy was a stranger two hours prior and now my precum was lining the walls of his rectum. I fucked him slow for about five minutes then he wanted to go get in the sling. 
I pulled out of him, grabbed my towel and led him to the sling room, my hard cock swinging out in the open. We got to the room and he got in the sling as I shut the door. I lined up my cock with his hole and sank back in again. I grabbed the chains of the sling and used them to swing him back and forth on my naked cock. I told him in a few minutes he’d have his ass filled with a strangers cum. He squeezed his ass on my cock and told me to fuck him faster and breed him so I started slamming my cock in and out of him, feeling my orgasm build. A couple minutes later I told him to get ready as my orgasm hit and I started shooting inside of him, still slamming my cock in and out. 
I finished cumming and pulled out of him and watched as some of my cum leaked out of his ass onto the floor below. He told me that was his favorite part and we went and showered and left. I went back to work, wondering what my coworkers would have thought if they’d known I’d just bred a stranger on my lunch break. 

About a year later he texted me and told me he was poz and I should get tested. I was fine but he said I should get on prep. A few months later I saw him on Grindr and said hi. He asks if I wanted to hook up again and I said of course. I got there and he was in a jock and harness again and as I was undressing he said I could use a condom but he was undetectable. I lined up my cock and sank it bareback in him and a few minutes later I unloaded into his poz ass.
