So I had been out of work for what seemed like for-fucking-ever when I finally landed a job at JFK as a security guard in the parking structures. It’s not the best job in the world, but it’s a steady paycheck and it’s not like the work is hard. It’s a lot of walking around and keeping an eye out for suspicious activity. Of course anyone planning on doing anything bad is already suspicious himself, so he’s not doing it when I get there, but whatever, man. I don’t care. Money is money at this point.

The other guys who’ve been doing this a lot longer have some fucking ridiculous stories about the stuff they’ve caught people doing in the parking garage. Hot stuff, too. Seriously fucked up shit, in fact; but then if you could actually managed to get it up in that cold, gray concrete car zoo that smells like piss and exhaust fumes, you’d have to be a freak.

At least that’s what I thought up until last week.

I’m walking around, doing my usual rounds, and not seeing much of anything going on. It was chilly that day, it had been drizzling most of the morning so the wet tires were squealing more than usual as they turned the corners. If you’ve ever been in a parking garage on a wet day, you know what I mean. It sounds like someone’s stepping on a cat, and after awhile, it’s all you can hear.

The noise must be the reason I didn’t hear them at first, or why they didn’t hear me coming. I turned the corner and saw a guy out there with his lady friend. Her eyes were closed and her head was back, and at first I couldn’t quite see what was going on. But I got a step closer and caught sight of one luscious, creamy tit hanging out there in the cold. The guy leaned close and took that sweet, hard nipple in his mouth and I was all, “HELLO.”

Now, I knew I should get in there and break it up. As soon as I knew what they were up to, I should have stopped it. But her face was so beautiful. Her mouth was open slightly and she was breathing hard, and she would lick her lips making them red and shiny. I could tell that she was so turned on that she didn’t care who was looking, and before I knew it, I was rock hard. My cock was straining against my zipper and I had to reach down and adjust a bit.

I know it’s wrong, but I slipped behind one of the big, concrete support pillars and shielded myself behind a nearby Suburban. I watched the guy as he slipped a hand down her pants, and I could tell just by the way she squirmed and moaned that he found her clit and was going to town on it. He was fingering her like a violin and she was going fucking nuts.

She had her hands all over his crotch, fumbling with the button, and I have to tell you, mine throbbed in sympathy. I reached down and stroked myself through my polyester uniform pants and thought I’d cum right then and there. She was rubbing him through his pants, humping his hand, and when she opened her sweet mouth and sucked his tongue, I couldn’t stand it anymore. My mouth was dry and my cock was so hard it hurt. I went to unzip my pants and rub one out, but my nightstick banged against the side of the Suburban and made a huge, metallic bang.

Her eyes flew open and I didn’t have much of a choice at that point. I cleared my throat and walked up and hoped to hell they couldn’t see my dick was at full attention. “Everything okay over here?” I asked, trying to look imposing and not like a kid in a costume with a raging boner.

It must have worked, because he turned around, yanking his hands out of her cunt so fast I could see her pussy juice still shining on his fingers. He yanked the tails of his flannel shirt down and stuffed his hands in his pockets, but I could see that he was as hard as I was, and his cock was at least as big. When I looked up, the girl had zipped her pants and I caught sight of that beautiful, big tit as it disappeared inside her sweater. She was blushing and shaking a little and in my mind I could see how hot she’d be wrapped around my cock, her legs tight around my waist as I drilled her up against her boyfriend’s truck. Her tits would be bouncing around and she’d scream my name as she came…

I shook my head and stammered something about them having to do that somewhere else, and they nodded guiltily. I think she even called me “sir.” I walked away, but I had to look back over my shoulder. She looked every bit as hot as she had before I’d interrupted and I hoped they’d take their chances and finish up, but they caught me looking and got into his truck.

I heard them leave, and I knew they were off the floor when the tires of his truck cat-squealed on the wet concrete. I stopped walking and leaned against a minivan to catch my breath and compose myself. I couldn’t remember the last time I was that turned on. My dick felt ready to explode.

I looked around quickly, and seeing no one, I slipped between the van and a black sedan and unzipped my pants. I pulled my cock out and grabbed it, stroking it hard. “Oh God,” I said, and my voice echoed and bounced around the cars in the enclosure. I bit my lip and ran my hand through the spunk that was already drooling out of the tip and started milking my cock for all it was worth. Every shriek of tires made me jump a little and I hammered away at my dick, scared of being caught, scared of losing my job, scared of being arrested for indecent exposure, but nowhere near scared enough to stop.

I came harder than I ever had before. My balls tightened up in the cold air of the garage and I had to lean on the car so that my legs wouldn’t give out under me. My cum shot out in long, white curving arcs and splattered on the tinted windows of the shiny black car. “Oh, God,” I said again, both from the exquisite, throbbing, pounding release of my orgasm and because I realized I’d left slimy gobs of my DNA all over a brand new Mercedes.

Embarrassed and ashamed, and not having anything to clean it up with, I tucked my sticky, still-hard cock back in my pants and got the hell out of there as fast as I could, looking all around and hoping no one saw me.

I didn’t think to check inside the car, though. And in this story, that’s where the fine line between really bad luck and fortunate accident is.
