Supermarket Sex

At the supermarket a few weeks ago with my girlfriend, a guy I'd met at a cruising place calls me over.
A couple of days before at a gay cruising place I'd sucked his dick and was just about to get fucked as I leaned against a tree, when we got disturbed by a dog walker, who then stood watching us walk back to our cars.
Walking with the supermarket worker into the back warehouse, he leads us into a small room.
He has me sucking on his dick for only a minute before he pulls me up, spins me around and has me drop my jeans and boxers.
Seconds later using just saliva, he's sliding his cock up my arse and begins fucking me.
Hammering away for only three or four minutes, he unloads up my arsehole and pulls out.
A minute later I'm walking back towards my girlfriend near the clothes section with his cum leaking out of my backside.
I tell her I need to use the toilet and go in.
There's an older man in there (50's maybe 60's) Without me saying anything or hinting in any way, he begins stroking his cock in front of me.
He asks me if I want his sperm and we end up in the cubicle.
Sucking on his short fat cock for no more than a minute, he cums in my mouth, wipes his cock on my face and gets dressed.
Spitting out his jizz into the toilet, I wipe my arsehole clean of my previous guys spunk, have a pee, wash my hands and rejoin my girlfriend.
She's still in the clothes section and non the wiser I've just had sex with two men in the supermarket.
