Meeting On Friday

On Friday this week I'll be meeting a twenty eight year old recently married man early in the morning, while it's still dark.
Well both drive over to a place he's recommended, where no matter the weather or temperature, I'll fuck him as he lays naked on a very old stone slab.
He wants me to sacrifice his arsehole with my large cock, and using his phrase, bum him until he spurts his spunk onto the stone.
I'll be emptying my balls up his arsehole, because that's what I do to the guys I fuck.
We have fucked before, but not in the open air. Now I'm really looking forward to thrusting into his arsehole, as he cries out from his orgasm.
