LET ME GO!!!

*pat pat* @N@ Poor poor muscled monstery dude~

Now, GentleLadies and UngentleMen, would you explain to me how the hell you managed to a) capture such a buff specimen and b) stuff him into your kinky sex-cave /-dungeon without anyone noticing? D8<
Admit it >w>/ You want to wiggle-waggle on his joystick for a little while, don't you! Also this must be one of Forge's infamous magic glowy cockrings. Wonder where he sells 'em!

Rubilax's Woes (travisbuchanan's short story, approved by the author)

“So here’s what’s interesting about you.” Your voice was faintly amused as you glanced down at Rubilax. The demon growled at you, struggling, but you’d been sure to bind chains around him that changed with his size. It didn’t matter how large he grew - the chains would just grow along with him and keep him bound in place.

Besides, it wasn’t like he was in control of his size change, anyway.

“You’re not actually in control of your abilities.” You folded your arms, fiddling with the remote you’d created. It connected directly to the control ring that’s wrapped tightly around the base of the demon’s cock; you still had no idea what energy it used to function the way it did, but…

Well, throw enough science at something, and you usually figure something out. Case in point! While you still had no idea how to directly control the energy in the ring the way a mage would, you’d discovered that certain frequencies of electromagnetic radiation would cause the ring to react and activate. It was a step forward, and had been quite the breakthrough.

The next step, of course, was figuring out if the ring had any effect on the samples you needed to collect for your work. You’d already done the requisite testing on non-magical beings; now it was just a matter of making sure it didn’t taint samples from magical creatures as well.

Which led you to now, with a captured Shushu bound to your service.

“Like hell I’m not.” The demon’s words were a low, dangerous growl - a threat in spite of his current incapacitated state. You tilted your head at him, then turned a dial on your remote. “G-graagh, w-what…”

Rubilax’s body shuddered, his cock suddenly twitching and growing to full hardness where just an instant before he had been entirely flaccid. In a mere moment he was leaking, precum sliding out of his shaft and dripping onto his lower abdomen. The demon’s eyes gleamed white as shuddering pleasure slid through him, and slowly - very, very slowly - his body began to grow.

“You absorb kinetic energy, but the rate of your growth isn’t proportionate to the amount of kinetic energy you absorb,” you continued, just as though Rubilax wasn’t desperately holding his moans back in the background. You tapped at your remote once or twice, and the demon gasped, his entire body arching into the air as the ring began to vibrate.

“F-fuck-!” Rubilax cursed. He writhed on the ground, straining against his chains - but try as he might he couldn’t break free. He wasn’t even sure what he would do if he did; strangle the strange creature that had trapped him, perhaps, or…

...or give his dick the attention it craved. He was so hard, achingly hard, moreso than he could remember ever being.

“The obvious explanation, of course, is that you’re getting your energy from somewhere else. Kinetic energy is just a trigger.” You pretended to be oblivious, but you saw Rubilax shaking with pleasure in the corner of your eye, and it took everything you had to hide a grin.

“So what if we gave you a different trigger? Just a slight alteration of your magical chemistry with the use of a certain ring, and we can make it so that the harder you get - the hornier you get - the more powerful you become.” You allowed yourself a smirk, looking down at Rubilax. “You like being powerful, don’t you?”

“...Power?” The demon seemed to be in a bit of a daze, and you couldn’t blame him. You prepare the sampling tubes you needed, keeping a careful eye on your remote - no point wasting all that delicious demonic seed, after all! The more he grew, the more of the sample you would get; that was the other benefit to collecting his seed like this. “Nngh… A trick! Let me go!”

“No tricks,” you promised, folding your hands carefully behind your back. You strode confidently towards the rather confused demon, dialing up the remote as you did so. Rubilax’s body stiffened and arched, and he let out a confused moan as his body grew once more; he was a good deal larger than you, now, enough so that you could comfortably sit on his abdomen.

His cock pulsed and throbbed in front of you, large enough at this point that you could easily wrap your arms around it. You didn’t, of course; that would be far from sanitary. Instead, you reach out with a finger and dabbed it in the flowing precum, now copious enough that you’d have to hire another employee just to get the floor of the cave cleaned up.

Ah well. Whatever was necessary for science.

You licked the demon’s pre off of your finger, savouring the taste - hygiene should never get in the way of good science, after all! Rubilax was moaning and shuddering underneath you, squirming against the floor of the cave. You chuckled, looking down to your voice recorder.

“Demon’s taste remains unchanged despite magical influence… commencing full test,” you mutter into it, then twist the dial all the way up on your remote.

You didn’t quite expect Rubilax to expand all the way up to the size of the cavern you’d placed him in, nor for him to shudder and shatter his restraints in an effort to reach his cock. You moved out of the way in time for him to grip and groan, stroking it at a feverish pace as the ring glowed and vibrated around the base.

It took only a minute of solid stroking before he abruptly came, vast torrents of cum flooding the caves. Even as prepared as you had been, you couldn’t quite capture all of it; it left you with a slightly shocked expression on your face as you were drenched with his seed.

Then you remembered that you had more important matters to deal with - Rubilax was free, now, and would do to you whatever he wished. You glanced at the slowly shrinking demon, who was…

...looking away from you sheepishly?

“I, uh… Don’t suppose you can do that again for me?” he asked after a moment. The demon’s tone was meek. “...Master.”

You grinned. Alright, well, if that was what worked.
