Seracen whistled as he read, a mindless tune. Today he was in male form, which really wasn’t that different from female form. Beneath the tail was really the only change. The dragon was sitting in the entrance to his cave, safely out of the sun and bright light but close enough for there to be a breeze that played over his scales.

Magic helped keep the pages of his book from rustling and flying up as he read, but otherwise his concentration was solely on the text. This one was a compendium of fictional stories from one of the local authors and he devoured chapter after chapter with bright eyes, not pausing for a moment. He had planned to go to Malv’s today, but that could wait a bit. Malv probably wouldn’t expect him until evening anyway, when it wasn’t so bright and more comfortable for the black dragon.

He grinned to himself, thinking back to the last time Malv had come over. That had been a fun bit of magic, turning his friend into a plushie. Nice to sleep with and cuddle at night. He’d been female through that encounter but Seracen squirmed as he felt his cock poke free of its sheath at the thought of their last meeting. It had only been a few days ago; he’d let Malv go soon enough, as promised. The dragon lifted a hind leg, smiling as he looked down at himself.

He’d gone for a more external configuration this time, with a sheath and balls visible just behind it. Sometimes it was merely a slit on his underside, not that different from a female sex, but he’d had a sudden compulsion to do this for a while. He shrugged, trying to concentrate and push the thoughts of Malv from his head. The way she’d been transformed into a conscious, inanimate toy, frozen on the edge of cumming, so sensitive everywhere and filled with need but no hope of release…

With a huff, Seracen slammed the book shut. That wasn’t helping! Looking up, he saw that it was dark enough anyway; he could go to Malv’s now and put the thoughts of his plushified friend out of his mind. He placed the book down on a pile that was nearly as high as his shoulder. As the thick, leather-bound book was put down on the top, the entire pile teetered dangerously. Seracen winced, ready for the crash, but it didn’t happen. The pile was on a lean, but apparently not enough to fall. With a sigh of relief, the dragon looked around at all of the other piles, many tilted dangerously as well.

“Should use the shelves more often,” he mused to himself, look across the big room. There were lots of fallen piles around. Even now, as he looked across the cavern, a pile of encyclopedias in the distance fell over. He winced and waved a paw. “Take care of it later,” he said. Walking to the entrance of his cave, he shivered, wings springing into existence on his back. 

He flapped them a couple of time experimentally, leaving the entrance to his cave. Behind him, it became a little misty, the only sign of the magic that kept it hidden. Malv and, of course, Seracen could find it, but no one else. He didn’t get many visitors anyway. Spreading his wings, he took off, flapping hard and rising quickly. Malv’s home was fairly close, just about a twenty-minute flight from his own.

The sky was a bright orange colour as the sun set but it had already mostly dipped beneath the mountains, and it was to the dragon’s back anyway. Seracen landed at Malv’s, giving a quiet roar to announce his arrival. There was a blur from inside as Seracen was busy removing his wings, getting them out of the way, before he let out a yelp, bowled over as Malv slammed into him. The blue and yellow dragon growled, pinning the black dragon beneath him. Seracen noticed that his friend was also male now as well, but he was distracted, giving another yelp as Malv bapped the end of his snout.

“Hey!” Seracen protested but he was bapped again.

“You still haven’t been forgiven, you know,” Malv growled, bapping him a third time. “You turned me into a plushie! A needy, plushie toy!”

“Hey, I turned you back,” Seracen protested again. “After a little while…and I let you cum when you left!”

Malv huffed into his face at that, bapping him once more but climbing off him. “You did,” he admitted. “But that doesn’t make up for all of the teasing and denial!”

“It does a little,” the black dragon said, waving a paw and walking inside. “So, what do you have planned this time? You usually have something nice when I come over; a game or…or…or…”

As Seracen walked into the cave, he spotted something right in the middle, right where his eyes were naturally going to land. It was a gem on a pedestal, like a sapphire but glowing with a faint, internal light. “What is that?” he said, moving closer. There were so many facets, the light inside seemed to glimmer and dance with every movement of his head. Malv didn’t answer and Seracen closer. It was getting increasingly hard to look away, or do anything that wasn’t staring. “What…is…?” The words trailed off, Seracen’s mind becoming hazy and his thoughts indistinct. He was present enough to know that it was some kind of magic but here, away from his own home, the black dragon’s powers were vastly reduced.

His jaw dropped open, mind filled with the light from the jewel, unable to even make himself move. All thought turned sluggish, moving so slowly it seemed frozen. “Oh, this,” Malv said with a laugh, walking up besides Seracen. “This is just an ordinary gem—with a little hypnosis magic added! Effective, isn’t it?” He petted the black dragon’s head, between the horns, but Seracen didn’t respond, just staring blankly into the crystal.

“Hehe, you turned me into a plushie, but I have a special plan for you,” Malv said, moving in front of Seracen. The blue and yellow dragon picked up the gem, Seracen’s eyes following it, not letting it out of his sight for even a moment. Holding the gem in his paw, Malv stepped back slowly, Seracen following immediately as the gem pulled away. Malv used the hypnotic crystal to lead the black dragon further into his home. “That’s it…just follow the crystal…”

Seracen didn’t speak, just staring hard into the gem. It was so hard to think, so hard to do anything but just look… Malv was smiling widely, and he set the gem down on the floor, Seracen stopping to just look at it. He didn’t react as Malv began to walk around him, running a paw down his haunch. Even when Malv pushed his tail up, the black dragon barely twitched, keeping his tail in the same position. Neither did he react as he ran a paw over Seracen’s ass, giving it a firm grope.

“Stay here,” he smirked, the order unnecessary; Seracen wasn’t moving an inch while under the crystal’s spell. Chuckling, he went to a chest, opening it and rummaging around inside for a few moments. He pulled out a grey visor made of tinted plastic. Just below it though, something caught his eye: a metal ring and cage. “Hehe, this will be excellent payback. And just to make sure you learn your lesson, I’ll be keeping you for at least a week, just to make sure this sinks in. But first…”

He set the chastity device and visor down on the ground beside Seracen. “I think we should change…you, just a bit. Especially because you make it so easy.” He stepped behind the black dragon, looking beneath his raised tail. His tailhole and balls were clearly visible. “Why not add a little back here?” he mused, giving Seracen’s ass a soft spank. “Change into a herm.”

The order resonated in Seracen’s mind, empty apart from the crystal’s light, and the thought of resisting didn’t even occur. A shiver ran through his body and his body shifted. Beneath his tail, just above his balls, a set of lips appeared, a hint of pink flesh visible. Malv grinned, licking a finger and pushing it into Seracen’s new tunnel. The black dragon let out a soft moan, clenching a little on the finger. Malv pulled his digit out, quickly grabbing the chastity device. The tip of the dragon’s cock was poking free from his sheath at the bit of stimulation but Malv tutted.

“Uh, uh,” he said, slipping the cage over Seracen’s sheath before his length could grow anymore. He slipped the ring over his balls as well, locking the cage on and snapping a small padlock onto the entire contraption, sitting back. Even with the hypnotic crystal, Seracen let out a little groan as his cock tried to grow a little more and hit the metal of the cage, aching a little as it was stymied. “You can stay with that locked up for as long as you’re with me. But now for this…” 

He returned to Seracen’s front and picked up the visor. Carefully, he put it onto the black dragon’s face, the visor fitting perfectly. At that moment, the visor attached itself to his face but it also broke his eye contact with the crystal, Malv then sitting in front of it. Seracen shook his head slightly, in a daze as his mind began to clear. There was a tingling around his face where the visor was attached. “Wha-what?” he mumbled as the tingling spread.

Malv smiled. “Just wait a moment.” 

Seracen took a step back, groaning again as he felt the hardness of the cage around his sheath, as well as the slight warmth in the feminine sex beneath his tail. The tingling was moving, running down his neck with his face feeling pleasantly cool and almost electric. Malv reached out, running a claw down Seracen’s jaw and the black dragon let out a surprised moan. That felt powerful, his scales extra sensitive. The tingling reached his chest just as he reached up to the visor, trying to take it off. To Seracen’s surprise, he couldn’t find the edge; it seemed to have sealed itself directly to his scales.

He looked down at himself, gasping a little. The blackness of his scales was changing, shifting, becoming shinier and more…rubbery. “Latex?” he said quizzically, his own voice sounding a little different. The magic wasn’t just for his scales either; he could feel it deep inside, turning him fully to magical latex. The change began to spread faster and he moaned at the sensations, eyes closing as his front legs were changed. Seracen looked at his paws and they were different, simpler and without claws.

“Latex,” Malv confirmed cheerfully. “You’ll be my rubber drone, for as long as I want.”

Seracen was going to say some snappy retort but he was much more interested in watching the changes. He slipped over onto his side, watching as the latex moved down his belly, heading right for his chaste cock. As his internal organs shifted into latex, he felt biological needs vanish. Air, water, food, he could feel the desire for all of these disappear, no longer needed. The changes didn’t affect the cage but he felt his sheath turn to rubber, the sensation of which made his now black length press all the harder against the chastity. “Ngh,” he panted, moaning louder as his balls changed as well, seeming to swell a little larger.

His sex was next, Seracen giving an even louder moan as his folds changed to black rubber. The rest of the changes happened quickly, his tailhole and tail turning to latex so quickly he was barely able to feel it. It wasn’t the limit to the changes though, the next part more subtle and insidious. As Seracen got to his feet, he looked towards Master. Wait, was that who he was? No, the blue and yellow dragon wasn’t Master? It was…Master?

“All done?” Master said, smiling widely and running a few claws down Seracen’s side. The new drone moaned, hips bucking slightly as the cage grew tighter. At the same time, synthetic lube began to drip from his female sex, the same lube in his tailhole but not dripping out. With the visor over the top half of his face, he was practically anonymous. “Excellent. Now, what do you need to do?”

Seracen began to speak almost before his mind had registered the words, the response automatic and meant wholeheartedly. “Serve and please you, Master.”

“And what do you want to do?”

“Serve and please you, Master.”

The blue and yellow dragon grinned, beginning to get hard himself. His own length began to emerge, hardening rapidly as Seracen’s visored face turned towards him. “You know what to do,” he said, pointing down at his length. The dronified Seracen moved at once, dropping to his belly and extending his muzzle to his master. He took Master’s length into his maw, teeth now soft rubber but tongue still nimble. He licked, sealing his lips on the cock in front of him and beginning to bob his head.* Serve…please…Master*. The rubber dragon’s sex clenched on the emptiness inside it, more fluid gently trickling out of the latex folds, making them glisten.

Master moaned, putting his paw on the back of his drone’s head, pushing him a little further down until Seracen’s nose was pressed against his yellow belly. With no need for air, Seracen could stay that way, with the tip of the dragon’s length at the back of his throat as he licked and sucked. A little precum came from Master’s tip as he stayed like that more than a minute, moans and soft huffs coming from the biological dragon.

He let Seracen pull back and then pushed him off completely as the drone went to bob again. “Not any more of that,” Master said, panting softly. “Turn around, tail up.” Seracen didn’t hesitate. *Serve Master. Obey Master. *He turned, raising his tail high and displaying his caged cock, balls, sex, and tailhole for Master’s view. There was a growl of appreciation from the dragon behind him, the drone standing still as there was a puff of air against his balls as Master nosed at him. 

Seracen moaned as a tongue flicked out, running along his balls and then over the slit above them. Master chuckled, fondling the cage and the sheath beneath it with his paw, Seracen’s cock trying to grow more, the pressure growing. “Very nice,” purred Master. “Which part to use first? I want to try out all of you, including that cock of yours. Get hard, now.” He smiled, pausing a moment. “Bet that feels frustrating; trying to grow that rubber cock and please your master, but stopped by the hard metal…”

The drone groaned again, bucking his hips slightly. Master wanted him hard, but he couldn’t do it! The ache in the ruber dragon’s shaft increased. That was soon a secondary concern though as Master reared up, the blue dragon putting his weight on Seracen’s rear as his cock pressed against the latter’s balls, tip poking up. For a moment, Seracen tensed, thinking that he was going to thrust into his sex, but Master moved higher still, the head of his cock pressing against his tailhole instead. The drone’s body was made to be taken there so when Master pushed in, his ass was slick with lube as well.

Master’s moans mixed with those from Seracen, pleasure exploding through the latter’s body as the tight rubber ring was spread. The blue dragon huffed in pleasure, nipping at his drone’s neck as he thrust into his ass with long, smooth strokes, the latex tailhole spreading easily and the lube inside slick. Seracen moaned as well, feeling the pleasure just build and build, cock getting harder. Beginning to thrust faster and harder, Master’s moans grew in volume, pleasure building in both of them.

Seracen didn’t fail to notice, rocking slightly against the blue dragon, that as the pleasure got stronger it didn’t seem to be building to anything. His tailhole felt amazing but it didn’t seem to be going towards any climax or orgasm that he could feel. The part of him that wasn’t completely subject to the visor surged, letting him whine, before the programming came back. 

Meanwhile, Master moaned and roared, thrusting deep into his drone and staying there, cumming powerfully in a way that Seracen just couldn’t. He panted, nuzzling against Seracen’s neck as he let loose pulses of seed into the rubber tailhole. “Mmmm,” he purred, making small rubbing thrusts. “That felt good. Since plushies can’t cum, neither can my drones.” He nuzzled more firmly against his drone, laugh echoing around the cave.

“Don’t worry though; that cock will stay locked up while I use the rest of your holes.” His tail curled around, squeezing around the cage and making the rubber dragon moan, grinding into the touch as well as against the length in his tailhole. “I can’t wait for this week.”
