I still remember that morning in 2012, at the end of my second year at university. It was a warm summer’s day, almost too hot for a run, but I’d been working hard to get myself properly into shape before my holiday, so I was determined to stick to my weekly schedule. My fitness trainer had recommended a few circuits of the local park every Sunday morning, to augment my daily workout, and I hoped if I worked up a good sweat, I might even burn off a couple more ounces than usual.

I put on just a pair of tight blue running shorts and a rather skimpy cropped red running top that kept my little tits in place while showing off my trim tummy. I looked at myself in the mirror and wondered for a moment if I was maybe showing too much flesh. But hey, I knew I’d be more comfortable like this, and if I got a few admiring glances along the way, then no harm done.

I jogged down the road to the local park and began my first circuit. There was a small lake at one end, surrounded by trees, and a larger open area beyond, mostly grass, with some tennis courts at the far end. Sometimes I’d run full circuits of the park, but in view of the heat I decided it’d be more comfortable to stay under the trees as much as possible and do a series of circuits of the lake instead.

As I’d hoped, it was slightly cooler under the trees, and I enjoyed the feel of the fresh air flowing past my legs and over my bare tummy. I knew my bum looked good in my tight shorts, and before I’d done even half a circuit, I’d noticed several other runners glancing at me as they ran past. I glanced at them too, looking at the bulges in the shorts of the male runners and imagining what their cocks looked like, as I always do.

As I rounded one end of the lake and started to jog along past a grassy bank, I saw a guy sitting there wearing a tight Lycra top and cycling shorts. As I got closer I could see a very prominent bulge in his shorts. Goodness, that was quite a package he had in there, and the clinging Lycra meant that the outline of his cock and balls was very obvious. He definitely had a bit of an erection, and I gave it perhaps more of a glance than necessary as I jogged past. I caught his eye and gave him a quick little smile. How he took that was up to him, but I was definitely impressed by what I’d seen.

In fact, I couldn’t get it out of my mind as I ran to the end of the lake and finished my first circuit. I couldn’t help thinking what it would be like to slip his shorts down and get my hands on his cock. How big would it get if I stroked it for a while? And what if I put it in my mouth? If it was as big as it looked, could I swallow the whole thing? What would it taste like if he came in my mouth? Or should I let him cum on my bare tits instead, so I could see how thick it was?

Sorry God, these were dirty thoughts for a Sunday morning. But what with the heat and my filthy imagination, I was feeling pretty horny. At this rate, I’d have to go home and masturbate to calm myself down.

As I started my second circuit, running along the near side of the lake, I looked across the water to see if the guy was still there. Yes, he was, sitting on the grassy bank as before, but my heart gave a lurch as I looked more closely. It was a bit hard to see from this distance, but I could swear he had his cock out of his shorts and was stroking it. His hand was in front of his crotch, and there seemed to be a big fleshy rod in his fist.

Woah, if that’s what it was, it was pretty enormous. And wasn’t he taking a bit of a risk, getting it out in public like that? What if someone saw him? Apart from horny girls like me, that is.

As if to answer my question, I saw another female runner come along the path on his side of the lake, and he quickly slipped his rod back into his shorts.

In a couple of minutes, I was round the end of the lake and approaching him again. His cock was still back in his trousers, and I couldn’t help feeling disappointed – I knew full well that flashing unsuspecting women in the park wasn’t acceptable behaviour, but what if the woman didn’t mind being flashed? I’d always been a bit of an exhibitionist myself, and I knew the “rules” were different between men and women. If I went out in a loose strappy top without a bra and let people get a peep at my bare breasts, that was kind of okay, but a man flashing his meat and two veg in public was definitely frowned on by society. I could see why the rules were necessary, but I kept longing for some hot guy to break them when I was just passing by.

This time, I slowed down as I jogged past and made it clear that I was looking at his package. His cock was definitely rock hard in his tight shorts, and I swear I could see the outline of his knob at the tip of his shaft. I looked him in the eye and smiled. He smiled back, then reached down and ran his hand across his bulge.

Oh fuck, I wanted to stop and have a proper look, but I didn’t quite dare. I looked back and saw he’d slipped his hand down inside his shorts and was clearly touching himself. Jesus, what would it feel like inside me? The big knob stretching my pussy lips apart, before slipping into my wet vaginal passage…

I was getting way too turned on by this. I stopped for a moment and slipped my hand inside my shorts. I could feel the heat from my pussy, and two fingers slipped inside me so easily. It was like putting them in a warm wet squishy bag, and I almost came right there, pumping them in and out a few times. But I saw someone coming towards me, so I pulled myself together and my fingers out, and jogged on, sniffing my juices on my hand as I went.

As I reached the far side of the lake once again, I looked across to see if he was still there. I found myself worried that he might have gone, deciding he’d already gone far enough, but luckily he was still there, and again I could see his erect cock out of his shorts. This time he left his hands by his sides, and his erection reared up in full view. He was looking across at me, and in a moment of madness I pulled my top up, letting him see my little bare tits. I felt so naughty doing that, and I actually ran on for a short way with them still exposed, jiggling on my chest.

I was so excited that I very nearly took my top right off and jogged topless, but I chickened out at the last minute and pulled it back down again. But my heart was beating faster than usual as I approached my guy for the third time. There he was, and this time his cock was still out. I almost stumbled as I got closer, my eyes fixed on his erect shaft. It was big and thick and meaty, and he had his hand around the base as I ran past, just giving it a little tweak.

Fuck, I wanted to stop so much, but I didn’t dare. Then, as I jogged slowly past, I looked back and saw a little spurt of pre-cum shoot out of the end. That was it, I just couldn’t go on. I turned and ran slowly back. Reaching the guy, I sat down not quite next to him, not actually looking at him, and slipped my hand down the front of my shorts and began to rub my clit. I glanced sideways at his erection, then slipped a couple of fingers inside myself.

My guy actually looked a bit worried. I thought maybe he hadn’t expected me to turn back and sit down. I smiled at him to put him at his ease. “Don’t stop,” I said, “Look, I’m doing it too.”

Quickly I lifted my bum and slipped my shorts down so they were round my thighs, then spread my legs a little. Now he could see my pussy as I fingered myself. I’d recently had a full wax, so I was totally hairless, and there was nothing to hide my fingers as they slipped in and out.

“I’ve never done this before,” he blurted out suddenly. “But you looked so pretty that I couldn’t help touching myself in my shorts. And then I got hard so I took it out to rub. And then you didn’t look shocked, just interested. So I carried on. I’m sorry.”

“Don’t be sorry,” I replied. “I wasn’t offended at all. You have a lovely penis. Can I touch it?”

“I’d love it if you did,” he said. So I edged closer until my bare arm touched his, which made him jump a little. He was obviously more nervous than me, so I reached out and took his erection in my hand. I could only just get my hand right around it, and I reckoned it was a good eight inches long. I’d also never held one so hard – it was rock solid, totally engorged with blood, with very little of the natural flexibility of most hard cocks. I gripped it gently and pumped it up and down, letting his foreskin close over the tip then slide back to expose the shiny knob again.

“Oh God,” he gasped. I looked around nervously as two other runners jogged past, but they were chatting and didn’t even look in our direction. Once they’d gone, I bent over and took the tip of the guy’s cock in my mouth. The knob was smooth and warm, and I ran my tongue around the ridge at its base, making him gasp with pleasure. Although his cock was big, I was confident I’d be able to get most of it down my throat. I’d practiced hard to perfect my deep-throating skills, and it was always a pleasure to try them out on a new example. Slowly I began to slip the shaft into my mouth, letting it slip out each time I sucked on it, then slurping it back a little further.

My willing victim was gasping with pleasure as he felt his rod sucked deeper each time. Then suddenly he pulled back and covered his glistening shaft as another jogger ran past, much closer this time.

“That was a near thing, we were nearly caught,” he said, though I got the impression he was getting a kick out of the possibility of being seen. Good, because so was I, and frankly I wasn’t going to be interrupted again. With one swoop I took his cock in my mouth again, this time relaxing my throat so the first few inches slipped straight down. Even so, I almost gagged – the hardness of the cock was an extra challenge – but I’d done it. I let it rest there for a minute, licking round the shaft with my tongue, then let it slip out again, giving me a chance to catch my breath.

He reached out and began to play with my breasts through my top. I love having my tits fondled, so I quickly pulled my top up and let him see them in all their 32b glory. Small, but firm and very squeezy. He tweaked my nipples, making them go hard, and then leant over and sucked on them one by one. My pink nipples were soon tingling with arousal. I reached down and began to play with his cock again, cradling his balls with one hand while rubbing his shaft with the other.

Tit play always gets me really turned on, and I could feel my pussy juices starting to dribble down my thighs. I was so turned on by this time that if I didn’t get some sort of release I’d explode. I pulled my shorts right off and spread my legs wide, letting him see my puffy aroused pussy lips.

“Fuck me, quick, before someone else comes” I gasped. He got the message and quickly pulled off his own shorts before straddling me and pressing his hard cock against the entrance to my vagina.

“Oh fuck,” he gasped, then pushed forward, shoving his cock right into me. I let out a squeal of pleasure as his balls slapped against me and he began to thrust in and out. The rhythm was making my little tits jiggle like mad, and I tweaked my nipples hard, loving the painful pressure.

As I gazed over his shoulder across towards the lake, I saw a young man walking towards us with a dog. I thought about warning my lover, but honestly I was past caring, and the last thing I wanted was for him to stop now that he was in me and going at it full throttle. The dog-walker saw what was going on and stopped in amazement. I saw him mouth the words “fucking hell” or something similar, and to my delight he got his own cock out and began to masturbate as he watched us fucking on the grassy bank.

Schlup-slurp, schlup-slurp, schlup-slurp went his cock as it plunged in and out of me. I could feel my pussy juices frothing out of me and dribbling down my legs. “Oh fuck, fuck, fuck,” I gasped, “That’s so good, don’t stop, Jesus fuck, I’m cumming, I’m cumming.”

Lubricating my finger with some of my juices, I began to rub vigorously at the hard bud of my clitoris. Soon I’d built up just the right rhythm, and the combination of this and his thick cock rubbing against the nerve endings of my vaginal walls brought me to a glorious fizzing orgasm. I squealed with pleasure and squeezed his cock hard with my juicy cunt.

“Shit and fuck, I’m cumming too,” he groaned.

“Don’t cum inside me, cum on my face, I want to see it,” I squealed with delight. He pulled out with a final “squelch”, then leant over me and gave his cock a few more rubs.

“Oh FUCK,” he yelled, and a big creamy dollop of cum spurted out of his cock and onto my cheek. This was followed by lots more, some of which went in my hair and the rest over my face. The last spurts dripped onto my little tits, coating my nipples and running down the sides of my squishy mounds.

As a final tribute, I saw the dog-walker ejaculate as well, his semen shooting out in front of him and over the path. He quickly tucked his cock back into his trousers and walked off with a grin.

“Ah fuck that was awesome,” said my lover, tucking his cock back into his tight shorts. “You’re amazing, you know that?”

“Well, you started it,” I said, pulling my top back up over my cummy tits. Dark patches quickly appeared as the cum seeped into the material.

“Do you want to wipe your face?” he asked.

I got out my phone and took a couple of selfies of my face, covered in rivulets of semen that were already starting to run down my cheeks and drip off my chin.

“No, I think I’ll finish my run like this,” I said. “If anyone sees, I’ll say I had an accident with some ice cream.”

“Fuck it, you’re my kind of girl. Maybe I’ll see you again?” he said hopefully. “Do you run here often? I don’t even know your name.”

“Annie,” I said. “And yes, I’m here most Sunday mornings. Sometimes I’m with my flatmate Katie. So next time, maybe you’d better bring a friend too.”
