I spent the summer after my last year of high school working at a restaurant on the west coast, at a small resort town on the ocean close in Sonoma, California. I had grown up in a smaller town in the middle of nowhere in Ohio, and wanted to see a bit of the country before starting college in the fall. I also wanted to find a way to forget about my last year of high school, which was extremely uneventful. At 5'9" and 140 lbs, I was definitely not the most athletic kid in school, and was mostly overlooked by everyone, especially the girls. I had long, shoulder length hair, fine features, and could barely grow a beard: not at all the football player type that suburban Ohio girls went for. I thought moving to California for a summer would be a good way to forget about high school before starting college.
While I wasn't especially athletic, I did really enjoy running, and I took full advantage of the trails outside of the resort town. The scenery was incredible, ranging from dense pacific forests to open ocean views and even took me by a few secluded beaches. I'm pretty introverted, and I wasn't really making any new friends at work, but I was falling love with the natural landscape and my secluded runs. Every 30 minutes or so I would bump into another jogger, but they generally seemed to be about as engrossed by the landscape as I was and didn't pay much attention to anything else.
Like any 18 year old with a healthy sex drive, I enjoyed jacking off pretty much every day. I don't know how or why - maybe it had something to do with being isolated and not having much of an outlet for my sexual fantasies - I started stopping in the middle of my runs to masturbate. At first, I would be extremely careful, going well off the trail and making sure that no one was around before pulling my shorts down a bit as if I was peeing, and jerking off as quickly as possible. But after a few careful sessions I realized that it was super unlikely that anyone would catch me, and that I could take my time, getting to the point where I would stop in the middle of the trail, pull off my tight running shorts completely, and spend a while pleasuring myself.
After a few weeks of this I started to play a new 'game' to test myself. I would strip naked, hide my running clothes in the bushes, and run for while wearing nothing but my shoes and socks. After I got too scared and excited, I would run back to where my clothes were and masturbate like crazy. All the running had given me a pretty slim and tight body, and I got into the habit of admiring myself while I was still naked before playing with myself. I was doing some stretches, my dick hard and pointing out, and while I was reaching up with my arms, my back arched and my ass slightly sticking out, I jumped as I heard a man's voice.
"Very nice" he said, smiling at me lewdly. "Smooth and you've got a great ass." He must have been in his early 40s, about 6'2" with a strong build and a beard. He was wearing shorts and a plaid shirt, with hiking boots and a backpack.
I immediately covered my front with my hands, facing away from him to hide my ass.
"Don't be shy now, I've been admiring you stretching for a while."
"Fuck off you pervert!" I yelled at him, finding my voice.
He just laughed at me. "You've been running naked on this trail for the past two weeks, jerking off like crazy after you finish because it gets you so horny, and I'm the pervert?"
I was shocked, I thought I had been so careful not to be seen by anyone. "Whatever, you're the one who's been spying on me this whole time, you dirty old man!"
I started walking towards the spot where I had left my clothes, careful to keep myself covered. "Oh, are you looking for these?" he said, holding up my shorts and t-shirt in his hand. I was getting worried now - what did this asshole have in mind?
"I'll give them back to you, but only if you finish what you came here to do" he said, smiling that same dirty smile.
"Definitely not happening!" I said, lunging to try and grab my shorts in his hand, but he pulled away quickly and I missed.
He just looked at me, still smiling. "Then you'd prefer that I send these photos and videos of you to your friends and coworkers, I guess?" He pulled out his phone and scrolled quickly through photos and a few very embarrassing videos he had taken of me masturbating. In one of the videos - it must have been two days ago - I was leaning up on my toes, ass sticking out and hand bracing myself against a tree, as I came, moaning like crazy.
I was wondering what had led me to jerk off like that, with my ass in the air and moaning in not the most masculine way, and, if I have to admit, getting even hornier thinking about it, when his voice brought me back to the current exceedingly awkward moment. "Here's the deal. I know you're working at one of the restaurants at the resort. I'm guessing you're saving up for college or something. If you jerk off right now - like you always do anyway - I'll give you 500 dollars."
I was about to turn around and run back to my apartment as quickly as I could, but I had to admit that this was kind of interesting. Sure, he was a pervert, but if it was only jerking off quickly, maybe it wasn't such a bad deal.
"Let's say I do that - will you delete the photos and videos you took of me?" I asked him.
"Sure, I'll even delete them right now" he said, showing me as he erased them from his phone and pulling out five 100 dollar bills. "And I promise I don't have any backups."
Was I really going to do this? I could definitely use the money, and he had already seen me masturbate so maybe it wasn't quite so bad. Also, I couldn't deny that I was even harder than usual, and was leaking precum all over my hands and arm.
I slowly pulled my hands away and started to do what this older man wanted. The thought of someone - anyone - watching me masturbate was incredibly arousing, and I knew I wasn't going to last very long. After only about a minute I was moaning softly, and when I looked up at him he was rubbing his crotch, still smiling at me. I blushed and looked away quickly.
He must have noticed that I was getting close to cumming. I was standing up straight and picturing a hot blonde girl bent over in front of me, grunting as I imagined thrusting into her from behind. "No, not like that" he said. "Do it like you did last time."
For whatever reason - maybe because I liked the idea of showing of for and pleasing an audience, even if it was just a dirty older man - I leaned up against a tree and got up on my toes, my ass out in the air. I closed my eyes and the picture of the hot blonde disappeared, as my moans became softer and higher pitched. I came harder than ever, my ass exposed, moaning through each spasm of cum.
I was embarrassed and filled with regret. The man clapped and whistled. "Lovely performance, glad I could capture it all for posterity" he said.
