I used to let this Latino guy, Alberto, fuck my bubble ass. He was older than me and I suspected he was HIV positive. Every time he put his huge dick inside me, it was bareback, and I had to insist that he wore a condom.
Fast forward a couple of years, after I got pozzed during Pride 2004. I ran into Alberto at the bathhouse, where I was face down and ass up in a room. Alberto came in and put the tip of his bare dick inside me. I reached around to feel if he was wearing a condom and of course he wasn't. I took a deep hit of poppers and then slowly backed my raw hole all the way down to the root of his cock.
We started to fuck intensely. My hole was devouring his poz cock. We took a break during which he said "I wish I could piss in your ass. I wish I could cum in your ass."
I leapt onto the bed doggy style ass up and open to let him know that he could pump my ass with whatever he wanted. In the end, he blew a load inside me, walked out of the room without me realizing it. He had left the door wide open, so everyone passing by could see my doggy style ass dripping with his cum.
