Nanite Fun

"So let me get this straight, then: they basically do whatever you want?"

"Yes they do. They're quite handy like that."

"Jeez, it's like Arthur C. Clarke mentioned: get it sufficiently advanced enough, and tech is virtually indistinguishable from magic, huh?"

"Precisely!"

"Yeah, I can see that. You're the tech guy, not me, so I figure you'd know better."

Art chuckled, looking over to the big dragon who sat next to him on the table. Dave was at work yet again calibrating the nanites that the parrot had only gotten a taste for: scheduled maintenance was the particular order of this day.

And so, there they were, at the dragon's work-station, the dragon typing into a computer. It was a simple diagnostic output, with numbers flying by on the screen. Art watched, half-mesmerized as he looked on, but mostly slightly confused at what the numbers meant. Even with Dave's explanations the numbers seemed strange, and as Art looked to the petri dish, he watched as very faint fractal patterns appeared on there.

The parrot exhaled, looking back at Dave. "So this is just something you do before seeing friends?" he asked.

"Yes," Dave replied. He relaxed his hand, placing it on the table. The nanites immediately flowed into Dave's hand, the scaly flesh almost soaking up those nanites. "Just to make sure it's properly maintained before I go there."

The parrot grinned, leaning against the table and running a feathered finger against the nanites on Dave's hand. "I guess he's in for a good time, eh?" he asked.

The dragon chuckled at this, the light bouncing off his black-and-red scales. "Depends on what you call a good time."

Art chuckled at this, sidling into Dave's lap. He ground his ass against the front of Dave's hips, winking at him suggestively. "What would you call that?" he asked.

Dave chuckled. "An incitement for punishment later," he replied.

The parrot laughed, throwing his head back into Dave's large chest. "Fair, fair," he said. "Well, hopefully he's not too far off, because this... Tal, was it?"

"Yes," said Dave. "He is quite a sweetheart, but he wanted something more adventurous today."

The parrot nodded, leaning back against Dave with a smile. "Well, let me know how it all goes, I'd be very interested to hear about it."

Dave could only smirk at this, twitching his hand with the nanites giving off an almost perceptible electronic growl. "Will do," he said. "And in the meantime, I hope you have fun with the kobold."

The parrot winked in turn. "You know it!"

----**----

Tal woke up as late as he typically did: he was not much of a morning person, and by that it was understood that he was never up before noon. This did not bother him as much, however, for it left him alert much later in the day, and with the help of a large cup of coffee he would be alert as an owl.

And after all, that evening he was expecting company, and it left him in the position of needing to prepare something.

Thus, the bull-dragon was stirring over a pot, the waft of a particularly strongly flavored pork stock wafting throughout his small kitchen when he heard the rather loud rapping on the door. The bull looked up, checking the clock. He smiled upon seeing that everything was right on time, and so he walked forward, a small little spring in his step as he opened the door.

"Ah, and there you are! Hi!"

Dave stepped in, the dragon clad in his usual leather get-up as he ducked his head under Tal's door. "Tal," he said. "So good to see you again!"

"Same," Tal replied. He looked up at the imposing dragon: feeling unusually small next to him. "I trust you didn't have a hard time finding this place again?"

"It's a small country cottage, it's not very hard to find," Dave replied. He then sniffed the air. "Pork stock?"

"Just making some for the road," Tal said. "Wanted to make some ramen later, so I just wanted to start building the broth now. That stuff's best done over a long period of time, you know!"

"I think I do," said Dave. "Plenty of time for what you wanted to experiment with, right?"

Tal nodded, guiding Dave to a couch nearby. "Yes." The bull promptly sat down, and Dave could tell that there was a natural curiosity in the way his eyes scanned over Dave's body. "You said the nanites could do anything."

"Chastity included," Dave replied.

Tal inhaled. "That's not exactly where I was thinking with that," he said.

Dave tilted his head forward, his brow raising up slightly. "Oh?" he asked. "And what else might you be thinking?"

"I've always wondered what it might be like to have a second dick in there," Tal replied. He glanced down to Dave's groin, leaning back and letting his smirk do the rest of the talking. "And, you know, also being bigger than I am and all that."

Dave blinked, leaning back slightly. "You want the nanites to transform you?" he asked.

"And turn this house into a castle if you could," Tal replied. "Although I understand that's significantly harder."

The large dragon let out a laugh at this, leaning back and briefly looking to the ceiling. "Not really harder, as much as it would be time-consuming and would take a lot of raw materials," he said. "But that is not what I am here for." He then looked to Tal's groin, noticing the strange way the bull's jeans bulged. "Your permanent lock won't be a problem?"

Tal shrugged. "Well..." He blushed, glancing to the side. "You know how it is with this. I haven't felt what it's like to get off in years, sometimes I wonder what it'd be like to get close again..."

Dave nodded, looking down at Tal. "And are you looking for a permanent transformation?"

"Depends," Tal replied. He looked to the floor nervously. "Truth be told, I haven't given much thought to whether or not I think it should be permanent."

Dave smiled, bringing a large hand onto Tal's comparatively smaller shoulder. "Well, let's think about it later, yes?"

With this, the dragon leaned in, Tal blushing at the size difference between the two of them. Tal was no slouch, what with being six feet tall, but Dave absolutely dwarfed him in every way that mattered. It was something the bull could never get over no matter how many times he met with Dave, and while he always liked being put in his place by bigger people Tal liked it the most with the imposing black and red scales in his face.

And as he looked up at Dave, he felt this would be a good day.

"Shall we take this downstairs, dear bull?" Dave asked.

Tal nodded fervently.

"Good."

And Dave smiled, looking down at Tal mischievously as his teeth glinted white in the light.

----**----

Once in the basement, Dave had taken great care to make sure the door was closed behind him. He towered over Tal, who made his way onto a particular work table. The smaller bull inhaled sharply, stripping down. He looked rather slender, but Dave's attention was drawn to the chastity cage over the bull's groin. Tal had never unlocked that chastity cage: whether it was due to personal choice or because he had lost the key, Dave had never gotten the chance to confirm. But in the end, he found he also did not really care.

And it especially would not matter in a few minutes anyhow, Dave testing the nanites between his forefinger and his thumb briefly as he approached. "Let's see what we get here, eh?" Dave asked.

Tal nodded: if he was nervous in any way, it did not show at all. "Let's do it," he said.

With this, Dave leaned forward, placing his large hand so it covered almost all of Tal's belly. Tal felt a rush of heat inside of him, one that gave him a nice jolt of surprise as he laid down on it. The heat began to multiply and intensify, and slowly, Tal began to feel a strange kind of growth take form over his body.

He looked down at his torso, at first seeing his muscles begin to bulge out much more than usual. His legs stretched out slightly, but mostly his pecs and his abs grew much more defined in such a short period. He also noticed with some amount of surprise that little spots of scale began to appear from underneath the patches of fur, with one rather prominent one coming up right above his heart. His tail, normally rather small, also seemed to have gotten longer, and he felt the way his ass cheeks parted slightly at how thick it got at the base.

But perhaps most pressingly, Tal blinked in shock upon seeing something along his groin: he felt a second cock begin to form, the flesh turning from the metallic black of a nanite to the firm pink of the flesh he had long locked away previously. It was flaccid from the beginning, but the force that he felt from how it immediately flopped onto his strong belly was enough to tell him how much bigger it was than the cock still locked up in a cage.

It was over in just half a minute: as soon as the rush of heat left Tal's body, the bull was left panting rather loudly, and he could not help the staggered exhale that followed this. He looked up at Dave, feeling the sensations of his new body course all over him.

"That... that felt like something else," Tal stated gently.

"It looks beautiful from here," Dave said. "He grinned. "How does it feel to be closer to your dragon half for once?"

"W-weird," Tal admitted. He looked over himself, and most prominently to the free half of his hemipenis. "Fuck, that especially feels weird."

Dave nodded. "You haven't felt how hard you can get in a while, huh?"

"Yeah." Tal exhaled, shaking his head. "It's just... so weird to see it just out and hard like that." He flexed his free cock, feeling how firm the flesh was and how constrained his original cock felt in comparison. "Fuuuuck, I haven't felt that in years..."

"Nor have you come in that time," Dave commented. He immediately let his index finger hover over the bull-dragon's new cock, swirling around. "I wonder what it'd be like..."

It was as Dave twirled his finger around that Tal felt himself start to grow hard. His freed cock began to snap to attention, and under Dave's light, teasing touch, it began to harden up to full length. It was quite impressive once it finally fully hardened, but Tal lost sight of how big it was after seeing just how good it felt to be hard again. He knew the two rods through his actual penis in the cage kept it from ever getting hard again, but he had not missed this sensation until now, and now that he knew what it was like again he could not get enough.

Tal felt something rush up his new cock like a fire rushing to get out. He groaned, slamming his back up against the table. Dave's hand pulled away, and the sensation immediately died down: it left Tal shuddering, in such a way that it stirred his balls in ways they had not been for years. "D-Dave..."

"Yes, Tal?" asked Dave.

Tal nodded. "God, that felt so good."

"What, this?"

Dave let his hand circle around Tal's new penis again, and amidst the haze of pleasure this second rush of pleasure conjured up Tal almost felt his new cock grew harder. It left Tal shuddering, letting out a soft moan as the sensation died down again as soon as the large dragon had pulled his hand away.

"A-ah God..." Tal exhaled roughly, looking back up at Dave with wide eyes. He turned down to his caged cock, realizing just how tight the cage felt in that moment. "Fuck me..."

Dave chuckled. "Oh don't worry, Tal, that's still in the cards," the dragon replied. He grinned mischievously, his hand hovering just above that hard length. "Of course, that's after I figure out whether or not to touch you like this..."

Tal began to nod furiously. "O-oh, please!" he said. "I haven't had anyone touch my cock in so long."

The bull-dragon blinked, realizing in shock how easily that had come out of him. The shock quickly faded, though, for he felt that buzz of pleasure radiate out again, Dave letting his hand hover over the cock as he contemplated that thought, his gaze seeming more intense than usual...

But Dave shook his head. "No, I don't think I will," he said. He then pulled up, opening his jacket as he inhaled. "I have other, much more interesting things in mind, after all..."

And with this, the dragon stood up, pulling the zipper of his leather pants down and revealing both of his massive-pierced cocks. Tal had known all about that famous double dick that Dave sported, but never did he think either dick was so massive. Both shone an angry red in the light, and the large ring pierced into both really gleamed in front of Tal.

The bull exhaled, shifting himself back. He was surprised, but he felt his free cock get that much harder at the prospect of having either cock anywhere near him. It was such an exciting prospect, being able to get so close to such a beautiful pair of lengths...

And indeed, Tal groaned as soon as Dave pressed himself forward, Tal's free cock sandwiched between Dave's much larger cocks. The dragon's eyes gleamed as he looked down at Tal, and he leaned in closer holding the ends of his cocks together.

"So tell me Tal..." Dave said. "How does it feel to be so close to a real dragon?"

With this, Dave shuffled forward, his two cocks brushing up Tal's length and sending a shudder of pleasure running up Tal's spine.

"O-oooooh!" the bull-dragon replied, leaning his head back and squeezing his eyes shut.

"I can't hear you..." Dave repeated the motion, Tal shuddering again.

"I, uh..." Tal blushed quite hard as Dave brushed that again, setting up a small rhythm as he moved. "Oh God..."

Dave leaned towards Tal, his muzzle hovering just inches above Tal's as he looked down. "Lost for words?"

"So good..." Tal nodded, looking up at Dave. "That's what I would get out if you'd let me."

Dave chuckled, the sound quite deep as he pulled back. "Careful," he warned playfully. "That kind of talk results in a bull-dragon never being allowed to cum ever..."

Tal blinked in shock, the prospect now seeming far too tantalizing with the way his new cock throbbed hard in desire. Before he could say anything else, however, Dave brought a paw up, effortlessly spreading Tal's leg. Soon after, Tal felt pressure at his ass, massaging a muscle he had not even realized had bulked up as that spread as well.

He shuddered the second he felt cold metal at his asshole, the feeling bringing a twitch up his whole freed length. "O-oh God!" Tal replied.

"Just call me Dave," the larger dragon replied, positioning himself above Tal. "All I am is a real dragon..." The dragon's wings flared out, and Tal noticed the way the black leather of Dave's jacket almost gleamed in the light. "And this dragon is going to show you what a real dragon does to someone in your situation..."

He then pulled forward, Tal feeling pressure against his asshole as he did, the area suddenly feeling slick. Tal had no time to wonder if that was also the work of the nanites before was spread open, and then moaned out when Dave slid in almost effortlessly. He let out a surprise moan the moment Dave hilted, his arms flopping to the side.

He found himself looking back up at Dave, his breath coming in shuddered gasps. "H-holy..."

Dave grinned. "Real dragon." He pulled back, thrusting back into Tal slowly. "Or have you already forgotten?"

Tal shook his head profusely. "N-no," he said.

"Good." Dave pulled his hips, taking the cock not inside Tal's ass and wrapping his hand around both his own and Tal's free cock. "Now tell me..."

Dave immediately thrusted forward, drawing a loud groan out of Tal. Tal was most taken off guard by the friction of Dave's piercing against the skin of his freed cock, and by how both the friction inside and outside of him sent a wave of pleasure coursing up his spine. Dave only kept a cocky grin, however, and he looked down at Tal mischievously.

"How does it feel to be compared to a real dragon?" Dave asked.

"H-holy..." Tal exhaled, looking up at Dave as he pulled back again, that piercing dragging against his skin a little more. "God..."

Dave grinned, thrusting back in and making sure his piercing smashed against Tal's prostate in the process. "Yes, we can be quite godly," Dave commented.

Tal chuckled at the end of his groan, flexing his legs slightly as he looked up at Dave. "Must you be so witty?"

"Only to you," Dave replied. He pulled back, thrusting back in almost immediately. "But you haven't answered the question: how does it feel to be compared to a real dragon?"

Tal opened his mouth to answer, but before any answer could make its way out of his mouth he groaned as Dave began to get a rhythm of rather rough thrusting into him. The stars danced in Tal's vision so profoundly that the bull-dragon could scarcely get a word out, even as Dave continued to press the question onto him.

It drove Tal wild with desire, but it was downright torture with his new, freed cock. He'd forgotten how it could be to be so hard, to have another man's cock rub up against his, to even have it free to get hard to begin with, and now that he was feeling sensations he had not felt in literal years it was driving the bull-dragon absolutely insane with desire. He tried to push back against those thrusts, and a part of him wanted to rub himself off to climax, buck up into that cock that was held in place by Dave's hand...

...but Dave pulled his hand away, letting his free cock flop just over the chastity cage that held Tal's other cock. Tal felt himself pulse, but he saw Dave's hand circle above the tip of his cock once again, and he felt the rush just stop.

Tal inhaled, looking up at Dave as the dragon grinned. "I think, Tal, you are about to be bred by a real dragon," he said. "Mmph, such a good boy..."

Tal cried out, his freed cock twitching as he felt Dave's thrusts speed up. He did not have to wait long, however, for then he felt something slick and wet fill his backside. Dave grunted, and then the free cock erupted in cum, splattering the white substance all over Tal's front side.

The bull-dragon inhaled sharply, feeling his cock twitch gently as he watched this happen. It had been years since he had felt the urge to cum, but now that he had seen what a truly draconic cock could do, he felt the urge to cum right then and there. All it would take was one more motion, one more stroke, maybe even one more touch...

But the feeling passed almost instantly. He definitely felt the wave crest and he felt tingly all over in the aftermath, but it was not accompanied by any feelings of relief. He had not cum at all, at least not physically. He realized faintly how strange it felt, but particularly at the strange mix of disappointment and relief he felt as he looked at his cock.

Dave chuckled. "Did you feel like cumming?" he asked.

Tal nodded. "Not really," he said. He turned to Dave then. "I guess even if I did feel it, you wouldn't let me."

"No," Dave replied. He leaned forward. "But we can't have that happening again, can we? So let's ensure it doesn't."

And with this, Dave swirled his hand. Whatever he did caused Tal's cock to shrink out of a strange lack of arousal. This was strange enough, but Tal gasped as soon as he saw the chastity cage already on his cock began to morph, as if growing a second holder.

Tal looked up in shock at Dave. "Wh-whoah!" he said.

But Dave's smirk remained on his face, and it left Tal only able to watch as his new cock was also enclosed in a similar black holder, now joined forever to the chastity cage that already held his original cock. The transformation happened surprisingly fast, and Dave's teeth glinted in the light as he looked down. It was all over in a few seconds, and Tal now found two pouches holding both of his penises in place.

Tal nodded. "You're playing a dangerous game there, Dave."

"Oh, I know, but I'm all about dangerous games with my friends." The dragon chuckled gently, circling his finger around the chastity cage. "Be a good boy, and I may let it come out to play. Very strong may, although I suspect you will tell me no when the time comes."

Tal exhaled, putting on a fake pout. "You might be right," he said.

"As I usually am," Dave replied. He flexed his hand. "The nanites can do just about anything, you know?"

"Yes," said Tal. He exhaled, looking at the ceiling above. "I guess we'll see what else we can get up to with them, huh?"

Dave chuckled. "For sure."

And he let that statement linger in the air as the two of them remained in place, Dave keeping his eyes on Tal as the bull-dragon moved his muscles, getting used to his new form.
