Copied from a post I wrote on Reddit:
This story is a true account of what is simultaneously one of the hottest things and one of the most "this could have gone bad real quick" things that I've ever done/has happened to me. There's a lot of setup, but I'm a fan of context.
In my early 20s, I would drive back and forth about 8 hours to school in Oklahoma. I'd visit home roughly once every couple of months, and for one reason or another, always ended up making the drive back to school in the middle of the night.
Being a typical 20 something, there are two facts that we need to remember - 1) I never wore anything besides gym shorts/ sweat pants if I could help it and 2) I was, of course, incessantly horny. It was only my 3rd or 4th late-night trip across Arkansas on I-40 when I realized this was prime "jerk & drive" time. My typical routine would be to stop for gas and an energy drink outside Memphis and within an a few miles, I'd have my hand under my waistband, groping my hard 6.5" cock.
The first few times, I'd just jerk in my shorts and then whip it out through the leg hole to cum into a napkin or something. Once I lost control and shot into my sweats (that made for a sticky drive). And then once I came very close to running off the road during a particularly intense orgasm. That's when I vowed to only edge while driving, and wait until I stopped somewhere to finish. That's when I discovered the setting for our tale - the White River Rest Stop.
This rest stop had to have been the original. I think it's since been torn down and rebuilt, but at the time, it was simply a parking lot and a cinder block building containing a male and female restroom. The door opened into a wall that blocked the view from the outside. Once inside, the men's had two stalls, a trough urinal, and two sinks. The first time I stopped here, honestly just to pee, I instantly thought it might be kind of cruisey - definitely had that vibe. But even though I started stopping here on every trip back to school - often blowing a load in the stall - I never saw anyone else in the restroom.
One night, on my way back from the Easter break, I had been playing with my cock through my shorts and edging for several hours. I hadn't gotten off in several days, and was especially horny. I noticed the rest stop was coming up, and decided to stop for my usual mid-drive nut.
I pulled into the parking lot, and as usual I was the only car there. I didn't even bother tucking my boner up into my waistband, and walked up the steps and into the bathroom with my shorts fully tented. I entered the handicap stall and placed the paper cover on the seat (I'm not a total animal) before dropping my shorts, sitting back, and slowly stroking my cock.
I soon realized that maintenance or whoever hadn't been prepared for how warm the weekend was going to be, as the in-wall AC unit wasn't on, and even with the door to the outside propped open, and it had gotten pretty warm inside the building. I quickly pulled my t-shirt over my head and laid it across the top of the TP dispenser. Feeling bold, and pulled my left shorts leg off over my shoe and spread out, relishing in the feel of my slick cock. I don't know if it was the pent-up frustration of not getting off, the heat, or what, but I started thinking about how hot it'd be to walk out and blow my load on the wall of the trough urinal for the next guy to find.
I slowly stood up, letting my shorts fall off my other foot, and slide the lock on the stall door. I stood there for a few seconds, realizing how utterly naked I was. I stepped back, letting the door swing in under it's own weight, and paused briefly before stepping out. There I was, naked except for my converse, free for anyone who walked in to see. I reasoned to myself quickly that I'd hear anyone pulling into the rest stop and have time to get back to the stall before they walked in. Besides, it was nearly 3:00am - no one would be stopping here at this time of night.
I gingerly walked the few few to the urinal and stood there, admiring my distorted, but plainly naked, reflection in the metal paneling about the square trough. As the adrenaline continued to pump through my body (as I pumped something else), I got braver (stupider?). I decided to walk over and watch myself in the mirror above the sink. I stood there for a second, watching myself stroke my hard cock. The longer I was there, naked and exposed, the more confident I became, but also the more I wanted to push the situation. Feeling secure behind the wall blocking the view from outside, I walked over and put myself in position to instead be the first thing anyone walking in would see. I stood there for a moment, feeling the slight breeze coming through the propped door. The coolness felt refreshing in contrast to the stuffy bathroom, and I cautiously poked my head out the door.
My SUV was still the only car in the parking lot, and I couldn't even hear any traffic up or down the interstate just 40 yards aways. That's when I decided I wanted to push this just a little further. From previous stops, I knew there was a sidewalk that led around the building to vending machines on the backside, facing the interstate. I began to think about how exposed I'd feel making a lap around the building. The thought gave me goosebumps, but also made my cock throb. I dared myself to make one lap around, and then I'd blow my load and go.
Stepping out of the building and into the yellow-light of the parking lot lights, I was almost overcome with the thrill of being so exposed and completely nude in plain view. I turned left and walked past the open door of the women's restroom before turning the corner and walking towards the back of the building. Once I reached the back, I realized how isolated the space was. A tall stand of pine trees blocked any view of the interstate, and the building itself blocked almost all the light from the parking lot. The only light was the dull glow of an ancient soda machine. I stopped for a second, hand lightly stroking my cock - some deep part of me wanted to soak it in. I leaned against a picnic table, jerking my cock and looking up at the hazy sky. I pretty quickly and unceremoniously blew a huge load across the packed dirt.
Post-nut clarity hit and I realized I needed to get my clothes and get out of there. I began walking back towards the front of the building and right as I turned the corner to enter the bathroom, I happened to glance back towards where my car was parked when I saw it - another empty car was parked right next to mine! How had I not heard them pull in?!? More importantly, where was the driver?
In the same split second that those thoughts hit my head, they were quickly replaced by the thought "get your clothes, and GTFO of here!". I stepped into the men's room and quickly saw the back of a stocky older man with his back to me, pissing into the trough urinal. He looked to be about 60 , wearing a white button-down fishing shirt and dark jeans, tucked into cowboy boots. He had on some kind of ball-cap over his shaggy gray hair, and I could see the handgun holstered to his belt (this was the middle of Arkansas after all).
As quickly as I processed his presence, he clocked mine and gave an involuntary glance in my direction. I could almost see his double-take when he realized I was standing there butt-ass naked. The 15 seconds that followed consisted of him shouting every conceivable cuss and slur he'd every learned. Key phrases that etched into my brain included "fucking pervert" and "gonna get yourself killed.
While he continued to yell at me (pretty sure he was still pissing too), I quickly ran to the stall where I'd left my clothes. I didn't even bother to put them on, instead grabbing them and digging my car keys out of the pocket while I made a run for the parking lot. I jumped in and was at interstate speed before I every even left the parking lot. I wanted to put as much distance as possible between me a JimBob. I was 20 miles down the road before I realized I was still completely naked. I managed to pull my shorts on (thank god for cruise control). I reached for my shirt and couldn't find it - I must have dropped it during the dash to my car. Luckily my suitcase was in the trunk, so during my next gas stop an hour or two later, I got a new shirt out and popped it on.
I know this was a long story, and realize how badly it could have turned, but it's still an oddly-fond memory and I'll admit I've jerked to the recollection of it more than once. But it was a long time before I could bring myself to stop at that particular rest stop again.
