The Demon's Dragon For Necross by Draconicon

"Well, this is one dragon who doesn't fancy visitors, isn't it?"

Greydrone shook his head as he glanced around the opening to the dragon's cave. It was ringed with runes, ones that were strong enough that the demon didn't fancy trying to get through them at the moment. They looked quite strong, and even extending a bit of magic towards them made them glow warningly. He didn't want to imagine what they'd do if he actually stepped into them.

Not to mention how quickly they'd wake the dragon up if I tried, he thought as he looked down the cave. Even if I got through them, he'd be up and ready, and I'd be exhausted, at best.

But he couldn't just walk away. After all, the dragon mage was one of his favorite feeding 'friends'. So easy to get under his foot and then have his fun with. For that matter, it was probably the reasoning behind all the wards; he hadn't let the big guy have all that much free time of late, considering how tasty he was.

"No reason to shut me out, though. I wonder if I -"

He drew his hand back just in time to avoid getting it zapped right off. When he'd extended it, the entire cave mouth tried to clamp shut on his hand, and in the instant before it moved, there was a sealing magic that would have kept him in place, making him a convenient target for the sharp and hard stones coming down. He probably could have survived it, but it would have hurt like hell.

"Yeah...I'm not getting in there anytime soon. But with all that..."

He didn't know as much magic as the bookwyrm in the cave, but he knew enough to know that a barrier was only effective on a few things at a time. If it was too vague, then it would rapidly run out of power, and then would be useless. So if the dragon had specified that it was not possible for a demon to enter, he might have forgotten to seal out a few of the demon creatures Greydrone carried.

Reaching into a pack at his waist, the demon rooted around until he found the fuzzy thing that he was looking for. Pulling it out by the back of its head, the demon smiled at it.

"Hello, cutie."

The creature was known as a Mentis Furis, a creature that had been created through a number of different experiments down in hell, but wasn't technically of the hellish realms. Instead, it was a parasite that was quite alive, and quite mundane in its own way. With a long but slender body, and long legs like a spider, it looked like a cross between the arachnid and the centipede, but quite small enough to do what it needed.

He laid it down on the ground, and immediately stepped back. He needn't have worried, however, as it immediately started crawling into the cave. Doubtlessly, it was attracted by the scent of a non-demon, another little trait that was good to have bred into it. The last thing that Greydrone and the other incubi needed was to have those little things crawling inside of them.

It disappeared from eyesight very quickly, but Greydrone had no intention of skipping the show. He took a few steps back from the cave entrance, just enough to be out of range of any of the wards by a good few meters, before using some of his magic. After all, just because he was an incubus didn't mean that he didn't know a few spells, and scrying - specifically, peeping - was a particular speciality of his people.

Locating the Mentis Furis almost instantly, he locked the scrying spell on it and followed it through the open tunnels of the dragon's cavern. He was a little surprised at the sheer amount of space that the mage had claimed, let alone some of the bigger caverns that the creature passed by.

That would wait for another time, however. For now, there were bigger things to be concerned about.

As the creature finally reached the dragon's bedchamber, Greydrone couldn't help but smirk. Draconicon - the dragon mage that had been so fun to play with in the past - still slept in the nude, it seemed. Laying on his back, no less, with his scaly rump slightly raised. It was probably no more than a pillow, but the demon liked to think that the dragon mage was subconsciously offering himself to be taken, just like he did when they played.

The creature knew what it was meant to do, and the Mentis Furis started scurrying across the floor. Doubtless, it was drawn to the scent of the dragon and the heat that the mage was putting out. The little things did like the warmer spots, the demon knew well, and there was one very warm spot that the creature would be heading for.

As the scurrying thing made its way onto the bed, the dragon rolled onto his side, and the demon grumbled. Though it was still a nice view - the dragon had a smaller shaft than many of his kind, something easy to mock and play with - it wasn't something that the parasite could do much with. It was too large for urethral insertion, and it needed to get to the ass. If the dragon didn't roll over again -

Thankfully, he did, flopping back on his stomach with his legs spread wide and his tail flopped to the side. The view was even better than before, letting the demon get a perfect glimpse of the dragon's puckered - and surprisingly loose - hole, as well as the ass cheeks that were shown at their full size, rather than shrunken behind an illusion. The demon smirked to himself, particularly as the little parasite crawled across the dragon's bed.

His hand started to slide along his cock as he watched the creature's head nudge at the dragon's hole. He knew how it would go from here. A little bit of slime would ooze out, easing the way of the creature to penetrate that rear opening. If the dragon had been female, it would have been crawling into the pussy or the ass, but either one would work.

The hole started to stretch as the creature's head pressed against it, and the dragon shuffled in his sleep. Greydrone could just imagine the slight moan that would be coming from the dragon's lips, knowing how his little friend loved being filled from behind. He teased himself more, squeezing the base of his shaft before running his hands up towards the head.

Inch after inch of the creature disappeared into the dragon's stretched out hole, and the incubus licked his lips at the sight of the legs pulling into the creature's sides, making it almost like a snake at the rim. But inside...mmm, he knew what would be happening inside.

Just as the last bit of the creature's body slithered in, the dragon rolled over once more, laying on his back. Greydrone chuckled at the sight of the dragon's cock starting to engorge, getting bigger and bigger as it rose towards erection. The teasing inside was already beginning, he could tell, which meant that the dragon would soon be feeling -

Draconicon suddenly arched his back in his sleep, and the incubus grinned widely as the dragon's cock throbbed, spurting cum all over the dragon's belly and covering him with the potent goo that the dragon produced. He loved the sight of the white droplets falling over his friend's face, over his chest, everywhere. The orgasm continued for a few soundless seconds before the dragon flopped back onto his back.

However, his cock didn't go down. Instead, it seemed to swell even harder, probably as a result of the aphrodisiac-filled 'venom' that the creature had just injected into the mage's prostate. It would be swelling, throbbing from the bite, and so very sensitive.

"That's it, dragon. Just let the parasite do its work, and then you'll be all ready for your proper place. My little plaything."

He settled in, teasing himself as he watched the process, knowing it by heart as the Mentis Furis continued to work on the dragon, sparking spontaneous orgasms, and teasing the dragon with more and more arousal as he continued to sleep on.

Greydrone leaned back against one of the trees near the edge of the dragon's cave, the six-armed incubus tapping his foot as he waited. The spell had shown the dragon waking up after nearly six hours of being conditioned, and he had little doubt that the big mage would be coming out, looking for something to sate his condition. It wouldn't take much to make the dragon want a little incubus sex.

Sure enough, the black dragon stepped out of his cave. Well, more crawled out, whimpering and panting like some creature in heat, but it still brought the big guy out of the cave and away from his protection. The demon nodded to himself, stepping out of the shade of the trees and walking towards the dragon.

He saw Draconicon look up at him, and he kept a grip on his own power, just in case something was left, but he needn't have worried. Those white eyes were glassy, glazed over with the dragon's own need for something. Greydrone smiled in approval, patting his leg.

"Come here, dragon. Come here, if you want a treat."

Draconicon would never have done that, if he had been sober by any stretch of the imagination. Yet, there he was, crawling across the dirt ground towards the demon. It was enough to make his cock spring to full hardness again, and considering the demon had enjoyed four orgasms while waiting out the dragon's conditioning, that was no mean feat. He laughed out loud, rather than chuckling, and patted Draconicon's head when he was close enough.

"Heh, you really are a big slut inside, aren't you? Didn't take you that long to come looking for someone to fuck you. Did you really need the help of my little friend, or have you always been looking for this?"

The dragon looked up, almost dumbly, with just the hints of intelligence left behind all the lust that he was feeling. Greydrone shook his head.

"I guess it was the right name to give those little guys after all. Mentis Furis. The mental thief. I don't know if you'll ever get fucked enough to be able to think clearly again..."

He grabbed hold of the dragon's ass, his lips turning up in a smirk.

"But I think that you have the best chance with an incubus, don't you think?"

The dragon nodded his head a few times, but Greydrone was pretty sure that was more due to the sheer lust and need to please that was going through the former mage, rather than anything more substantial. If there was any thought other than 'cock', 'fuck', and 'cum' in the dragon's head right then, he would have been surprised.

Greydrone snapped his fingers, creating a small collar which he wrapped around the dragon's neck, and then created a leash ending in a cock ring. It only took a second to slap it around the dragon's shaft, and then he gave the leash a little tug.

"Come on, Draconicon. We have a demonstration to put on with some of my friends. How to properly satisfy a subby dragon. I think you'll do very well as a demonstration, don't you?"

"Y...y...."

"Yes, master, isn't that what you're trying to say?"

The dragon nodded.

"Very good."

The End
