Late one night I was PNP with my slut buddy Rod, at his place. We were both way horned up after smoking and edging for hours, and we went outside by his car, dressed only in boots, harnesses and cock rings. His house was right across the street from a leather bar and store, and it was closing time.
We started taking turns fucking each other, when we noticed a car drive into the lot across the street. The driver got out, as though to piss, and Rod whistled to him, motioning him to join us. He looked around, then hurried over to our somewhat sheltered parking spot, and stood there watching me fuck Rod. Rod told him to start pissing on us, then he told me to pull out so the new guy could fuck him.
After a couple of minutes we switched back, so I was fucking Rod again, and dude started pissing on us again. Then Rod told dude to fuck me while I fucked Rod, which dude did happily. Both Rod and I were fit, muscled 40-something pigs, and people always liked to watch us fuck. So, dude shoved his dick up my ass, and I rode back and forth, from Rod's ass back onto dude's hard cock.
Soon dude started fucking me harder and faster, and Rod told him to "breed that slut", and then I felt his cock pulse again and again as he shot a huge load up my ass. Rod then told him not to pull out yet, but to finish taking his piss up my ass. I could feel the hot piss start filling my ass as I fucked harder into Rod, and I finally started shooting a huge load into Rod's slutty hole.
He immediately pulled off my cock, turned me around, and quickly pumped his Poz load up my cum and piss filled hole. Dude thanked us for the great fuck and left us alone, covered and filled with piss and cum. Oh, and while we were hard at it, a police car slowly drove down the street, but fortunately the cop didn't see our hot slutty action.
