I have to admit that I'd never really paid much attention to my body, just took for granted the firmness and the natural shape of the muscle I had. Well at least until I started to get older... I looked at myself a little more critically now, and started to see the lines around my eyes, the hair that creeped further and further back on my scalp, and up over my shoulders, and not to mention the podgy, wobbly belly that seemed to have formed where I once had a firm solid mass of muscle. The last straw was really when my doctor looked at me and said that I either needed to do something about my fitness (read that as weight...) or I would need to start medication... I guess you could say it was a wake up call.

And so... I found myself, under cover of darkness, starting, trying to jog...

My partner worked at a bakery, and so I found myself being woken up at 4am... I waited until he'd left the house before I forced myself out of bed, into a tracksuit and down to the local oval. I'd been maintaining the secret training regime for a couple of months now and the results were starting to show... I'd actually managed to get myself up to a solid jog, doing five laps of the oval before strolling back home at a more leisurely pace and collapsing back into bed.

I took it as a good sign when I started to think of other things when I jogged... things other than the burning of the cold air in my lungs and the aching in my legs... but that presented problems all on its own... have you ever tried to run with a hard-on? Not only distracting, it can be downright uncomfortable! I went out that afternoon a bought a jock strap, I'd always wanted one anyway, and I told myself that this was a legitimate (non-sexual) reason to have one... I stashed it under the bed to wait for the next training session.

The next morning I pulled the strap up over my hips, the new addition to my workout gear. I loved the feeling of my arse exposed in my track pants, maybe a little too much... I had to really argue with myself that a wank did not count towards my cardio-vascular exercise for the day! I laughed and forced myself out the door... my cock responded by getting even harder at the thought that my arse was exposed in public (well sort of, more than it normally was)... I noticed that I seemed to have gathered an audience, there was a car parked in the shadows under the trees, I took note of the rego, took a wide berth and continued my jog.

As the weeks continued, I stuck to my routine... the same car was there, and sometimes it was joined by another, along with the unmistakable sounds of fucking... on other days there was no one... but it became more and more common that one or the other of the cars would be there, until I started to take for granted that I would have `company' on my morning jogs. I don't know if they actually watched me, or if that was the paranoia talking... but I certainly felt like I was being watched, and that I may as well have been running naked.

It was a morning like any other when it happened... I had dragged myself out of bed as usual... I walked slowly to the oval... and then started my slow warm up jog... my first lap... I didn't see him hiding in the shadows. He already had his cock out, it was hard and he was stroking it slowly as he watched me, I'd passed him at least twice before I noticed the movement in the shadows. I ignored him and kept running, each pass I made he stepped a little more into the light, so I could see him more clearly, and see just what he was doing... On the final pass he was completely in the light... naked and stroking his cock... I wrote it off as a strange occurrence, down to the full moon as I wandered back home, but it was his cock I dreamed of that morning.

He was big... a solid mass of muscle... his cock was huge... a long thick slab of manhood with a distinct upward curve... I had no doubt whatsoever that if he ever had any trouble getting laid, all he'd need to do was flash that monster and any gay guy would be on his knees for him in a second... it was a beautiful cock and I found myself thinking about it all day. I was wondering if he'd be there the next day...

I couldn't help the slight twinge of disappointment when his car wasn't there... I jogged as usual and trotted back home. This pattern continued for a few weeks, and I came to the conclusion that I must have been right, and when I didn't drop to worship that cock immediately he decided I wasn't interested... I worked harder without the distraction of thinking about him and got used to him not being there.

I didn't even notice when he started coming back, I didn't see the car parked way up amongst the trees... and he stuck to the shadows when he came closer to watch me. I was really pushing myself and had gotten up to running 10 laps in around 20 minutes before I headed home... he'd obviously been watching me to know my pattern, and he knew I wouldn't be able to fight him off... if I even wanted to...

It was a cool, foggy morning I couldn't see much further than 5 metres in front of me, I pushed myself harder trying to beat my 20 minute time, I had my head down checking my watch at the last bend, my blood pounding in my ears... I didn't hear the heavy footfalls behind me until it was too late...

He crashed against my back, tackling me to the ground... my arms were pinned under me and his weight against me made it near impossible to breathe, let along escape his grasp. His voice was harsh in my ear, and his cock was already hard against my crack... "I've been watching you... you make my cock hard... and now you're going to take care of that for me... aren't you?" I wasn't sure that he actually wanted an answer... but I wasn't capable of one either way... my own cock had sprung to full attention as I gasped and grunted for breath beneath this monster of masculinity.

He pushed my track pants down over my arse exposing my arse to the cold morning air... I managed to grunt out a response... "Wait!"... He grumbled at me but waited... "Are you going to use a condom? Or lube? That monster is gonna tear my arse without it... there's some in my wallet..." He paused for long enough to rifle through my wallet and roll the condom over his cock, he shoved the lube against my arse and squeezed the tube... "Now you're gonna take my cock boy... and I'm not gonna be gentle..." He was true to his word... he pushed his dick at my tight sphincter... "Let me in bitch..." he growled... when that tight ring finally stretched around his cock he slammed it in the rest of the way, completely ignoring my discomfort...

He rutted my arse for what felt like an eternity... his cock was huge and I'm not sure I ever really adjusted to the size before he started fucking more desperately... and unbelievably... it got bigger... He pulled me up onto my knees and started fucking me with long strokes, I felt his cockhead pop out, only to be slammed back in again... my arse had completely surrendered to his size, welcoming it even as it sucked his cock back in... he held me hard to him as his cock continued thrusting, shooting deep inside my gut... filling the condom to bursting point... he collapsed against my back as his dick shrank from my arse and slipped out leaving my hole gaping and raw from his invasion.

He pushed himself up, standing in front of me he reached out a hand to help me up... the condom was tight and distended with cum even though his cock was soft... It was still a monster, even soft and I wondered at the strength of the condom that it survived the onslaught of his cum... I slid the condom off and his cum dripped to the ground... I took his head in my mouth and gently cleaned the cum clinging to his shaft... the taste was salty and warm in the coolness of the foggy air... I let him slip from my mouth and stood before him, close...

"You know you don't have to tackle people to have sex with you right?"

"Yeah, but I had to have you... and it was his idea..." He pointed towards the grandstand where my partner was sitting, "he said he knew you and you'd be into it like that... I guess he was right hey?" He laughed... seeming kind of uncomfortable now...

"Is that right? You wanted to watch me get fucked hey? How about you get fucked next time..."

I had a feeling that this wasn't going to be the last time I would be `ambush fucked' and it was going to make sex a lot more interesting... and public. I was glad I'd been putting in work on my body, and that there'd be people who were going to appreciate it!
