Mike and I were enjoying an early morning run through the woods as we do whenever he visits my wife and I. He was slightly ahead of me and, try as I might, I just couldn't avert my eyes from his swaying bottom, his arse cheeks rubbing together in the tight white shorts he was wearing. I knew I shouldn't be looking at him the way I was, but his arse was just so damned attractive and very very sexy.
Mike slowed down to allow me to catch up, at forty years of age I am still reasonably fit but not as fit as a nineteen year old who attends the gym regularly and plays football each week for his local Sunday League team. Mike smiled at me as I neared him, feeling a desperate need at the same time to relieve myself.
"I gotta take a piss, Mike," I said.
"Me too, dad," Mike replied, "best go in the bushes, don't want any dog walkers seeing us."
My son turned and headed off the main path down into the undergrowth where we would be safely screened by the trees. As the shadows from the trees fell on him, his bum looked even more succulent, accentuated by his skimpy shorts framed by his white matching sleeveless vest. I could feel my cock hardening inside my shorts and I willed it to go down as Mike stopped in the copse, reached inside the right leg of his shorts and took out his prick.. I stood next to him and took out my own appendage too and together we began to let fly with two gushing streams of hot steaming father and son piss.
"Fucking hell, dad," Mike said, "I need this."
"So do I, son," I replied as our pee splashed against the bark of the tree, "I was bursting."
From ogling my son's bum for the last ten minutes or so, I decided I couldn't resist it; I just had to sneak a quick glance at his cock. Fucking hell, he was big, just like his old man, a right chip off the block and a classic case of like father, like son if ever I saw one. Mike had his foreskin peeled back, as did I, and as he shook the last drops of pee from his knob, he smiled across at me.
"Like what you see, dad?" he said, nonchalantly.
I was taken aback by my son's direct comment. Obviously, in eyeing up Mike's prick, I had not been discreet enough. There was no point denying it, I had been caught, hook line and sinker.
"You've got a nice dick, son," I said and then, as a wave of nausea swept over me, I hastily added: "but I shouldn't be saying things like that."
"Why not, dad?" Mike rejoined as if this was the type of conversation every father and son had every day. "I've seen you ogling my arse in my shorts while we've been running and looking at my dick while I was pissing. If you want it, you only have to say."
By now, I too had finished pissing and the early morning air grew pungent with the scent of freshly disposed pee. I had thought my embarrassment would cause my cock to return to its flaccid state but when I looked down, it had grown to mammoth proportions and literally throbbed in my hand.
Mike turned and walked towards me, holding in his hand his equally throbbing cock, which was now as hard as mine after relieving himself. My mouth was watering at the sight, I had never in a million years dreamed that a moment like this would happen, despite having secretly fancied my adult son for the past year or so, and now here he was offering me sex on a plate.
"Dad," Mike said, sensing my dilemma, "there ain't nobody here but us chickens. If you want to suck my prick, then it's all yours."
I couldn't refuse an offer like that. Sweeping caution to the wind, I fell on my knees, oblivious to the stings from a few nettles, and looked up at my son. His cock, with his retracted foreskin and his big balls hanging out through his shorts as well, were being presented to me as if the taboo act we were about to embark on was the most natural thing in the world.
"Suck it, dad," Mike said, "I really need a nice hot fatherly blowjob."
"In a moment, son," I replied. Now that I had decided to abandon any idea of propriety, I wanted to admire my son's cock to the full.
"You have a beautiful prick, son," I said, "and such lovely juicy balls," I went on, reaching out a hand and cupping them gently. They felt absolutely delightful in my hand and with my other hand I gave several quick tugs on my cock.
"They're full of spunk, dad," Mike replied, "as I'm sure yours are. Now, don't keep me waiting, you horny sod, suck it. Suck it hard."
I reached round behind Mike and grabbed his arse cheeks, enjoying the luxuriating feel of his buns in my hands through the tightness of his shorts. A whimper of pleasure from Mike gave me the courage to continue and I pulled him closer towards me until his dangling cock was literally only an inch or so away from my waiting mouth.
"Fucking hell, son, your bum feels great in those tight shorts."
"Yeah, dad," Mike replied, "I like you touching up my arse. Now quit speaking and get sucking."
I wasted no further time as I opened my mouth and took Mike inside. I licked the tip of his knob for a few seconds and then took the entire shaft inside, taking it right to the back of my throat. The sun shone down on us and the birds were singing high up in the trees but, at that moment in time, it could have been pouring down with rain and I wouldn't have given a damn.
"That feels great, dad," Mike said as I went to town. Unbeknown to Mike's mother, I had sucked plenty of cock in my youth before we were married but this was the first time I had had a man's cock in my mouth for nearly twenty years and the fact that it was my own son's cock gave it a surreal feel, adding to the exquisite pleasure as we indulged in incest for the very first time.
"Hey dad," Mike said, after I had been blow-jobbing him non-stop for nearly ten minutes, alternating between sucking his prick and licking his huge sweaty balls, "what do you think of this?"
I rested back on my haunches and watched fascinated as Mike turned his back to me and slowly lowered his shorts. As his bare arse came into view, my excitement reached fever pitch. I had thought my son's bum looked fantastic in his shorts but it looked even more spectacular and exquisite in its naked form. His smooth hairless cheeks were nicely rounded in perfect proportion to the rest of him, perching nicely at the top of his athletic legs and his long narrow crack looked divine, dividing his bum into two beautifully separate globes.
