Mestren inched his head past the corner of his bedroom door, peering down the hall towards the bathroom. He had just heard the shower go quiet, and now he could see the stocky silhouette of his father behind the shower curtain. After a long moment, the curtain was pulled back, and a stark naked, lumbering tower of a dragon stepped out. A magnificent draconic mane of white hair, wet from the shower, wreathed his head. Long hours at construction sites had bulked up his arms and chest, the former of which were sleeved in onyx black, and his voracious appetite combined with many a detour to fast food restaurants had given him a nice gut, colored a bright crimson, just like those strong pecs. However, nothing could compare to the huge package between his legs. That big, barbed, dark red shaft topped by white pubic hair, those hefty balls... all of which the youth got an eyeful of as his dad turned towards the mirror to groom himself.

Gawking at his dad’s dick from his room had been a daily routine for Mestren for a few months now. From the day the youngling had discovered things like sex and orgasms, he had become increasingly enamored with his father, Ovren, finding every opportunity to take discrete peeks and glances. It seemed today he was getting the special treatment, too, as Ovren ran his hands over his chest and belly, slipping his other hand under his cock and languidly pumping it. Mestren stroked his own pubescent cock, a mere four inches at that point in his life, as he watched that sight with wide eyes, squeezing between his barbs and slickening it with his copious pre, a perk of being a dragon even at the young age of twelve. Mestren wasn’t nearly as well built as his sire. Though he took after him overall, and though his frame was beginning to show signs of the same stockiness, many of the boyish features of childhood remained, and his musculature was ill-defined, thanks to his more sedentary lifestyle. 

“Mmmm...” That deliciously deep baritone rumbled out as Ovren worked himself to half-erection before stopping to grab a towel from a nearby shelf and dry off his upper half. Mes almost whined out in frustration, but he kept quiet.

Ovren turned and walked down the hall, giving his son a full frontal and increasingly detailed view of his heavily swaying endowment, before turning into his own bedroom. Mes closed his eyes, trapping that lewd imagery in his mind, his pace speeding up. His breath hitched, and he strained to keep quiet as he covered the wall with his cum. After a few seconds, his cock was left dribbling onto his hand, and he was left panting from the intensity of his climax.

God, he wanted his dad so much. He was starting to lose patience with keeping his distance. Something had to change.

Maybe tonight.

-- later that evening --

After dinner that night, Mestren waited for his dad to retire to his room for the night, passing the time by playing video games and poking around aimlessly on the internet. Eventually, his door creaked open, and Ovren’s head peeked in, “Good night, Mes.”

“Night, dad.”

The big dragon’s heavy footsteps grew fainter as he went to his bed, and eventually, snores drifted in through the crack in the door. Mestren waited an extra five minutes before getting up from his chair as quietly as he could and slipping out the door.

He trembled as he stepped down the hallway, his heart pounding hard in his chest with apprehension and excitement. He had been building up all of his courage for what he was about to do that night. Even though his dad slept like a brick, there still remained that deep fear of what if?

Upon arriving at the doorway, he found it wide open, and his father laid on his back. It was summer, so the blankets were left neglected at the bottom of the bed, leaving the big dragon almost completely exposed, wearing naught but a jockstrap that was filled to the brim, white pubic hair poking out the top. His eyes were closed peacefully, his chest rising and falling with his breaths.

Mestren tiptoed up to the bed, coming to a halt as he stood over his dad’s crotch. He stood there for a short time, frozen, stuck between admiring Ovren’s perfect form and bolting back out to his room before he could get himself in trouble. Mes drew a shuddering breath, struck with indecision. After a moment, he shook his head, No, not now. I’m this close...

He slowly reached a hand out, hovering over that huge bulge, hesitating for one last moment, before laying it down on the fabric covering his father’s member. Mes felt his face heating up, and a spike of lust drove into his core. Ovren’s cock pulsed underneath the cloth, emanating a heat that surprised the young dragon. He rubbed it up and down slowly, and that meat shifted underneath, welcoming outside touch. He slipped his hand lower, hefting that package in his palm. God, it’s heavy... He moved his hand back up, gently hooking his fingers into the waistband of the jockstrap, lifting it away from the skin beneath, trying his best not to drag it down and risk awakening his father. Even then, it pressed up into the fabric, and upon pulling the waistband below the tip, Ovren’s shaft popped out, slowly starting to engorge from his son’s fondling.

Mestren gaped at its size. He’d seen how large it was many times, but up close, it seemed even bigger. It had to be at least six inches soft, and it was getting bigger as it hardened. Pre beaded at the tip, and just like his own cock, barbs lined its underside on either side of the urethra, and its strong masculine scent filled his nose. He took hold of it, marvelling at its thickness, as his hand couldn’t wrap completely around it. With his dad’s cock, the same one that created him twelve years ago, pulsating there in his hand, what Mes was doing finally began to sink in. I’m finally... wow... He gave it a few experimental pumps, working more fluid from the tip, which threatened to run down the side of the shaft.

He stuck out his tongue to lap up that pre, now dripping copiously, even more so than from his own cock. The shaft jumped, and Ovren made a noise, causing Mes to freeze, staring up at his father’s face. When the snores continued, he breathed a quiet sigh of relief. With that, he continued to lick at the tip of that fat rod, savoring its salty emissions. Soon enough, it was at full mast, just over nine inches in length, and seven around. Wanting more, Mes took the head into his mouth, suckling on it, feeling his dad’s heartbeat on his tongue as delicious pre dribbled onto it. With his other hand, he pushed his briefs down, which were now damp from his own arousal, exposing his own cock, a mere four and a half inches compared to his sire. He spread his pre around his head, and a groan slipped out from the sensation, vibrating up the dragonhood in his mouth. He almost didn’t care, this was all so fucking hot, he wanted to drink his dad’s cum, he--

The snores had stopped.

“M-Mes?”

The youngling’s eyes snapped up. Ovren stared down at him, a mixture of confusion, surprise, lust, and horror painting his face.

This was it. It’s all over. Mestren had messed up, and he would pay the price. The cock slipped out of his mouth, “D-d-dad... I--”

“Oh, Mestren,” The elder dragon’s hand lifted up, and the youngling winced, almost expecting a slap, but instead it came to rest on his son’s face, “You know this is wrong. You shouldn’t be doing this to anyone unless they say you can, much less at your age,” Mes’ face burned with shame.

“D-dad... I-I’m sorry... I wanted-d to... so bad...”

“Gods, is this why I saw you peeking around the corner so much, Mes?”

He’d seen that? He was really in for it now... “Y-yeah,”

Ovren sighed, and sat for a long moment, “I suppose I can’t blame you. I was a horny little bastard at your age too...” He seemed conflicted, inscrutable emotions working across his face in the dark. After another long moment, he looked his son in the eyes with resolution, “If you’re going to be having sex at this age, I want it done right.” He shifted his bulk, sitting upright, propping up some pillows behind him, then pulled Mestren up onto the bed, sitting him between his legs. He took hold of his cock, “Here,” He held it up to his son, “Get it nice and wet for me.”

For the third time that night, Mes froze. He couldn’t believe his luck. After a pause, he began his task with gusto. Slithering out his long draconic tongue, he angled his muzzle against his dad’s cock, wrapping his tongue around it, slathering it up and down, rubbing over and threading between those sensitive spines. Ovren rumbled appreciatively, “Wow, look at you... you’ve been waiting for this for a while.” He reached over and flicked the bedside lamp on, and for the first time, Mes could see all of his father clearly. That handsome, rugged face, lined with small ivory spikes round the jaw, crowned with two pairs of horns, an encouraging smile and trusting eyes peering down at him, that mess of white draconic mane splayed out against the pillows behind him. That strong, barreled chest that breathed deep as his son tended to his cock. Those huge arms, etched and built through hard work, one strong hand rubbing affectionately on the back of Mestren’s head. That big belly, protruding slightly above his groin, smooth and huggable. And that huge dragonhood between his legs, veined and spined, musky, girthy, and pulsating, with balls to match. It was the most beautiful thing the dragonling had seen in his life.

“Try sucking it,” Ovren again wrapped a hand around his meat, pressing it to Mestren’s lips, “You’ll like it,” The young dragon nodded dumbly, before once again slipping his lips over the head. “Wrap your lips around your teeth, don’t want any scraping now”, his sire gently instructed, “Take your time going down, no rush,” Mes did as he was told, sliding that fat meat further into his maw. Once again, he thanked his draconic heritage, as it allowed him to open his jaws wider than most other species.

Ovren watched as more and more of his dick disappeared into his boy’s mouth. When he had noticed Mes taking peeks around the corner so often, the thought that his son might be attracted to him had briefly crossed his mind, but he had quickly disposed of the idea, unbelieving that a child could lust after their own father. Showed how much he had learned over all these years. Put that in with marrying that hellion of a dragoness. Thank the gods he had divorced her and managed to take full custody before the matter could have affected his son’s development. And thank the gods for this moment now, where the one that mattered to him most was gifting him with the ultimate expression of love, his warm, moist mouth wrapped around the man that brought him into this world twelve years ago. It couldn’t get better than this. Well, it could, and he was planning on getting to that soon.

Mes’ muzzle met his dad’s pubes as he sucked in the last inch of cock. He breathed deep of that wonderful manly smell trapped in that hair, strongest here than anywhere else. Ovren’s meat now leaked pre directly down his throat, and the sensation of that whole shaft throbbing in his mouth pushed his arousal even higher.

“Alright, now start pulling off, nice and slow,” Though he hated to empty his muzzle, Mes knew this was the way forward. He drew back, dragging his tongue along the underside of that cock until he reached the top, “Now back in, wrap your tongue around it as you go,” Once again, he complied, curling that organ round, feeling the veins pulsing under it, reaching down about three quarters before pulling back again. “Thaaat’s it, mmmm...”

Ovren groaned as his boy began properly fellating him, working up and down with the finesse of a pro under his guidance, the sounds of suckling filling the room. Even with the boy’s excellent grades that proved how well he learned, the elder dragon didn’t expect him to pick up the art of cock sucking this well. He felt a hand slip under his balls, rubbing them softly as Mes continued. His hips rocked up and into that wet maw, almost without him realizing it.

Mestren was in seventh heaven, there between his father’s legs servicing his maker. His own dragonhood was rock hard and twitching underneath him, drooling onto the bed sheets, but that didn’t matter. His attention was solely focused on pleasuring his dad, his tongue now sliding up and down like a slinky, and from the sound of it, it was working splendidly. Ovren’s grunting and moaning was getting louder, more frequent, and the youngling knew what was coming. Replicating a move he’d seen in those videos on the internet, he took most of the cock into his mouth and twisted a hand at the base, the other continuing to shift between his father’s testicles.

“H-here it-- ahhh!”

Mestren’s eyes went wide as his dad’s cock expanded in his mouth, the urethra swelling against his tongue, before a jet of hot, thick seed hit the back of his throat. He pulled back, sitting the tip on his tongue, tasting the cum as it streamed out onto it, eagerly gulping down the stuff that gave him life. It was just as salty as the pre, but now with added musk and masculinity, and even a little bit of sweetness. He pulled back even more, wanting more of his tongue to be covered in this wonderful stuff. Above him, Ovren panted and moaned out, bucking his hips, causing Mes to accidentally let his cock slip out, and ivory painted his face. Mes took the head back in and drank the remaining cum, prolonging his father’s climax as he nursed it.

Ovren’s head fell back as he breathed heavily from one of the strongest orgasms he’d had in years. After taking a moment to collect himself, he looked down at his son with a small smile, “Damn... nice job, Mes.”

“Yeah... thanks dad.”

“Come here, Mes,” He beckoned, and his son clambered up to meet him, sitting on his belly. Ovren wiped the cum off Mestren’s face with a finger, then licked it off, “Sorry ‘bout that”. Mes giggled.

Mes’ eyes went wide as his dad moved in closer to press his lips against his own. A tongue bade entrance to his mouth, and after a small hesitation, he let it in, melting into the kiss. After several seconds, Ovren pulled away, “How’d you like that?”

“I really liked it, daddy,” The elder dragon grinned at the change in moniker. It’d been a while since Mes had called him that. He felt something poking into his stomach, and he glanced down to see his son’s rod, turgid and dripping onto his belly. 

Ovren wrapped his arms around his son, shifting to get up from the bed, holding the kiss as he did. Mestren wrapped around his neck and locked his legs around his waist in response. Ovren laid his boy, his amazing little hatchling, down on the bed, straddling him with his arms bracing to either side, resting his still erect dragonhood between his legs. He grinded himself against Mes’ pubescent cock, and the younger dragon whimpered at the sensation.

After a time, their lips finally parted, and Mes stared up at his sire, eyes half-lidded, “Dad... are you going--”

“Yes, Mestren,” the elder dragon smiled, “I’m going to fuck you.”

Those words spoken aloud in his dad’s deep baritone made Mes’ eyes widen yet again, and he drew in a deep breath, lust burning through him at those words and the thoughts they summoned. Ovren drew his hips back, letting his dragonhood come to rest at the base of his boy’s tail. Taking hold, he worked up from the tip, squeezing out pre and rubbing it into that virgin tailhole. When he had enough, he pressed a finger against it, testing it more and more until it gave way.

Mestren gasped as the digit slipped in, probing deeper inside him, spreading his father’s natural lubrication onto his walls. Soon, a second finger pressed in, and the two began to tenderly stretch his tailhole for the coming invader. Ovren milked more pre from himself, using it to push deeper inside as he added a third finger. Mes groaned in discomfort, and his dad scritched a finger behind his ear, “It’s alright... it’ll get better.”

And it did. Those fingers touched something inside the young dragon, and it forced a gasp from his muzzle as it sent a shock of pleasure through his lower half, his ass seizing up around his those fingers.

Ovren stopped, suddenly deeply concerned, “Did I hurt you?”

“N-no... that felt good, dad.”

“Mmm... I see I’ve found your prostate, then.”

“Wha-- oohhhh!” His question was cut off as his father’s smirked devilishly and those digits curled up, rubbing that nugget of bliss deep within him. Ovren watched as his son writhed beneath him, his eyes clenched as he reveled in the sensation. Little did he know what he was in for. He retracted his fingers from the tailhole, now sufficiently loosened.

Mestren opened his eyes, confused, “W-why--”

“Because you’re ready, Mes.”

With that, Ovren took hold of his cock once more, pressing it again to his son’s tailhole. The two stared deep into the other’s eyes, their hearts pounding, with nervousness, lust, and love for each other. Then the elder dragon began to push.

For a moment, Mes wasn’t sure if it was going to fit. Then the head popped in, and all doubts were erased. Ovren groaned out from the youngling’s tightness, pushing further inside, those spines popping in one by one as he went. Meanwhile, Mestren was in awe at just how huge his father’s cock felt in his ass, panting hard as it stretched him open. Soon enough, his brow furrowed as it became too much, and the advance stopped, “Just tell me when you’re ready, Mes.” When the pain subsided, he nodded, and Ovren sank ever more of himself inside.

They continued like this for a short time. Though Mestren was frustrated at seemingly how often they had to stop, his father was patient as ever, tamping down his instinct to ram the entire thing in. Eventually, Mes felt that belly press against his crotch, those pubes ticking his balls, and that heavy sack resting at the base of his tail as his dad bottomed out. He was so full of roasting dragon cock, its heat like a hot rod throbbing deep inside him.

“Ohhhh, Mestren”, Ovren’s eyes were screwed shut with pleasure at the sensation of being connected so intimately to his son, “I haven’t felt like this in years...” Mestren’s walls molded perfectly to his cock, warm and snug, shifting around him, struggling to get used to the feeling of penetration. He began to pull out, and Mes whimpered at the suddenly empty sensation he was left with, and at those spines tugging at his walls. However, as it then sank back in, it rubbed against his prostate just as those fingers did.

“Hahhhn...”

The thrusting began to pick up pace, and soon his father was truly making love to him. Ovren wasn’t just fucking his son for his pleasure, but tenderly showing him just how much he meant to him, giving Mestren the best time of his life that he could. He paced himself, not just so he could savor the sensation of that tight tailhole clenching and rippling around his cock, but also so that he could continue to watch his beautiful boy melt into a puddle of blubbering ecstasy beneath him.

Mes never thought in his wildest dreams that anything could feel this good. He moaned and cried out in bliss, occasionally punctuated with a “daddy!”, holding onto the elder dragon’s shoulders for dear life. That dragonhood struck his immature prostate like flint against steel, creating sparks that set his body alight, those big, full balls tapped the base of his tail, and that belly rubbed against his own dick, smearing pre all over himself and his partner. He pulled Ovren down into a kiss, this one much more passionate than the last one, and their tails intertwined in an unconscious show of affection as Ovren wrapped his arms under and embraced his boy.

Eventually, it all became too much for Mestren. Tensing up, he screamed into his dad’s mouth, and his ass began to quiver and spasm erratically around that fat cock as he was blasted into the stars by the strongest climax of his twelve years on the earth, and his dragonhood spat cum all over his front, spurting seemingly without end. Ovren was surprised by the suddenness of his son’s orgasm, and his thrusts became more erratic.

One. His hips smacked against the younger dragon’s, and he felt the tingling build up deep within him. Two. Another thrust, and he felt himself pass the point of no return, and he broke the kiss to let Mestren’s cries free. Three. With a plap, he hilted firmly inside, and his cock began to jump and twitch, and he opened his mouth to roar.

Mestren, in the throes of his peak, felt a torrent of the very stuff that created him shoot deep inside him, searing hot and plentiful. Ovren bucked into him instinctively, his member pulsing hard with each spurt of thick, white, virile seed into his son, his head pressed against Mestren’s and his eyes clenched as he roared and growled like a feral. Mes wailed out and shook with euphoria as his father filled him, drawing out his orgasm as he continued to shoot all over his front. He never wanted this to stop, he wanted to spend eternity in this beautiful, perfect world, there under his dad with his thick, throbbing cock buried balls deep inside him gifting him with his essence, their essence, marking him and bonding them together in a way a father and his son should be, but hardly ever knew.

Eventually, though, the flood within lessened to occasional jets, then to dribbles, and then finally to a halt. His own cock had stopped its pumping as well, and in the end, Mestren was left covered in his own emissions, and filled to the brim with his dad's cum. The two panted hard from the exertion of their tryst, staring deep into each other's eyes.

“Gods, I love you so much, Mestren,” Ovren slipped his arms under his hatchling, drawing him close, uncaring of the mess that plastered his front. 

“Y-you too, dad,” Mrs couldn't find more words to say, but thankfully, there were none. All that could be said between the two didn't need to be.

Ovren's length had softened by now, slipping out of his son's no longer virgin ass, which gaped slightly from its girth. A trickle of pearly white soon followed from it. The elder dragon shifted himself onto the bed, rolling Mes under him so the two could lay facing each other. There the two basked in the afterglow of their consummation. A deep contentment filled Mestren now, safe in his sire's embrace, closer than he'd ever been to him, in more ways than one. He sighed deeply, eyes half lidded with satisfaction and sleepiness. 

“Hey, Mestren?” That chest rumbled with Ovren's voice, though the question itself was soft. 

“Yeah?” 

“Please don't ever leave me, will you?” 

A small smile tugged at his lips, “I won't, dad,” 

With that, his eyes slipped shut.
