Rhem buttoned up his lab coat and walked over to his seat in the observation room, which of course was directly in front of the wall-sized window that looked into the experiment lab. The chubby panda got himself comfortable in the padded chair, putting his arms up behind his head and putting his feet up on a nearby console. "And this, my friends...", Rhem started, "is our reward for years of hard work." The lab room itself was large and mostly empty this morning. At the moment, the little dragon "volunteer" was strapped down to a table in the center of the room. Built into the ceiling above the table was an assortment of robotic arms, probes, and mechanical devices. A few consoles that were bolted to the ground near the table glowed softly with some green and red lights as they displayed an array of information graphs and charts on the subject. But that was for experiments that were run with technicians in the room. Today's experiment was being run from the safety of the observation room, so all of the same information was also being routed to the terminals in there. The lab boasted a freshly clean and waxed ceramic tile floor. The walls and ceiling of the lab were a solid composite material not too far off from fiberglass. Florescent lights dotted the ceiling, and a large cargo door on one wall allowed access for larger pieces of equipment to be brought into the lab if the situation called for it. Rhem moved his foot and gently pressed it down on the intercom button next to where his feet were propped, "Mr. Rex, can you hear me okay in there? We're about to start, so sit back, relax, and enjoy the ride." Rhem then moved his foot back and looked over to Christopher, the lead scientist, and gave him a nod. Chris nodded back to Rhem and started issuing orders to the technicians seated at the control panels. Moments later, the mechanical apparatus in the ceiling above the green dragon suddenly sprang to life. Little gears started to spin, a bit of cold steam rolled off some of the tubes and ducts that connected to various parts of the device, and a flurry of little lights lit up along the length of the arm. The arm eased down from the ceiling slowly, moving to a point about halfway between the ceiling and the table. It paused there before slowly moving to one side, then rotating to the opposite direction. After the little mechanical hand spun around a few times, the lead technician called out, "All equipment checks are clear. Movement is normal, calibration is within parameters." Rhem flicked his little round ear, "Glad to hear it. Proceed." The mechanical arm moved back up to the ceiling. Two more robot arms descended from the ceiling, with what appeared to be flashlights on the ends of them. They took up positions on either side of the little dragon subject, hovering about a meter above and to the side of him. The lights activated, and the dragon was bathed in light as the scanners measured out his bodily dimensions. Next, the lenses in the lights shifted and the beams of light became much more narrow. The arms started moving around, scanning the dragon's insides and measuring out his internal capacities. When they finished, they ascended back into the mechanical device and locked into place. The first mechanical arm slowly emerged from the ceiling again, hovering almost menacingly above the poor little dragon strapped down onto the lab table below. The arm moved just past the end of the table by the dragon's tail, then it moved down and plucked something out of a cubby hole in the table. It pulled up above the table to reveal a small hose with a very smooth silicone tip. Draco Rex's eyes locked onto the little hose and he let out a small, almost inaudible whimper. He fidgeted around in his restraints, but they were all too tight for him to move anywhere. His balls twitched and his cock throbbed, letting a bit of dragon pre oose out of his cocktip and drip down onto his belly. The mechanical arm moved very slowly now, easing the end of the hose down near the tailbase of the bonded dragon. With the dragon's legs strapped down and spread far apart, there was nothing to get in the way now. So the arm moved the tip of the hose up to the dragon's exposed tailhole, rubbing the silicone gel tip around in a very gentle circle as a clear fluid oozed out of the tip of the hose and across the little green dragon's ass. Within seconds, the warming sensation from the lube kicked in, and the dragon seemed to relax a bit with a visible blush forming in his cheeks...and perhaps even a little giggle? Rhem wasn't quite sure if it was a giggle or not. If it was, the microphones inside the lab didn't pick it up, but he could swear the little dragon grinned and shook a bit. Next, the arm pressed the little hose against the dragon's tailhole. The tip of the hose slipped in through the greased passage without much trouble now, although the dragon's ass did clench down tightly around it. The hose moved in only a few centimeters before more lube streamed through the tip and coated the inside of the dragon's ass with the slick, warming substance. Then the mechanical arm moved the small, smooth hose tip back and forth slowly, working it around in a small circle to loosen up the dragon. The mechanical arm pulled back and moved down below the table again, dropping off the hose and picking up another device. It came back up with the torpedo-shaped, smooth-surfaced dildo. The little dragon looked down past his naked and helpless body, seeing the dildo being held by the device and hovering by the foot of the table. His eyes widened a bit and his cock twitched again, growing a bit more as it dribbled a bit more precum. The arm moved the dildo up slowly along the dragon's tail until it reached his tailbase again, gently prodding the dragon's anus with the tip of the dildo. After poking it a few times, the arm slid the very tip of the dildo in, carefully measuring how much resistance there was and making sure not to hurt the little dragon. The dragon's well-lubed ass spread easily over the tip of the relatively thin dildo, so the arm moved forward and eased the rest of the dildo in slowly, letting the little dragon adjust to the new intrusion. After giving the dragon a few moments to calm down, the dildo pulled out again and as soon as it was completely out, it pressed against his tailhole again, which opened right up for the dildo as it eased its way in. The dildo slipped in deeper this time, pushing in slowly until the base of it met the dragon's anal ring. The dragon huffed and moaned, clenching his ass around the dildo pressed so deeply in him, rubbing up against his prostate and making his cock squirt out little shots of pre all over his belly. With no more length to go in with, the dildo half-withdrew and started slow, deep thrusts into the little dragon's ass. The smooth dildo easily slid in and out of the well-lubed hole, pushing in as deep as it could go with every thrust. But then the mechanical arm withdrew the dildo and moved back to the foot of the table, returning the dildo from whence it came. But when the arm came back up, it brought another, larger dildo with it. This one was cone-shaped with a rather wide base and a blunt tip. The arm moved the dildo carefully over to the dragon's ass, pressing the tip to his tailhole and gently pressing forward. The dragon squealed lightly, but his lubed hole spread out around the tip of the dildo. The dildo pressed forward a bit more, stretching out the dragon's ass a bit more. The arm started moving the dildo back and forth, making it stretch more and more with each thrust. And just as the dragon's ass was stretched enough to take the entire cone dildo, the arm pulled back, giving the dragon a moment to rest and relax as it put the dildo back under the table. That's when the mechanical arm brought up the last dildo. It was brutally thick, it was blunt, it was ribbed, and it was veiny. It even had a little grinning shark face painted on the front of it. As the little dragon looked down past his spread legs and saw this dildo, his eyes opened up wide and he pleadingly looked over to the observation room. Rhem waved to him and pushed the intercom button, "You are such a trooper! You are doing great, don't worry!" Rhem then sat back and took a deep breath, taking a moment to look around the observation room. He had an throbbing tent in his pants, and he wasn't the only one either. Although he couldn't see the crotches of the technicians sitting behind their consoles, he could plainly see that the rest of the observer scientists were all hard under their pants. With a grin, Rhen moved his paws down and stood up, taking his pants off and flinging them to the side, revealing his thick, black, throbbing erection. The scientists looked over at him with a shocked look on their faces. "Oh don't get coy with me now. We're all enjoying this, we might as well forsake trying to hide it. In fact, it's an order. Everyone strip. [i]Right now[/i]." The scientists and techs looked at each other then back at Rhem. Rhem grunted, "I said, [i]now[/i]". Everyone in the room hesitated, but then finally reached down and unbuttoned their slacks, sliding them off and exposing themselves and their throbbing erections. Christopher, the Great Dane and lead scientist in the room, was hiding his privates behind a clipboard he was carrying. Rhem pointed at him with a wry smile and said, "Nu-uh! Let's see them. In fact, I want you over here right now. You're tall enough. I'm going to lean back in this chair, and you're going to stand up behind me here and rest your nuts on my head. I want your thighs pressing against my ears in ten seconds, my man". The panda turned back around to face the window and sat down in his chair. Chris looked around at everyone with an immense blush on his face before meekly walking up to his boss and putting his paw on the panda's seat, leaning it back. He then spread his legs and inched forward, rubbing his nutsac across the top of the panda's head, letting it come to a rest on his brow. The panda sighed happily as he felt the weight of the dog's nuts on his head. He leaned up, giving the nutsac a good lick and kissing it. "I've always loved your nutsac Chris. Your nuts are so large, so heavy, so firm". Rhem punctuated that comment by giving the Great Dane's sac a big, long lick. "Um, sir, the experiment...?", Chris said with a bit of a shaky voice. He had a bit of a dopey, blissful look on his face that he was desperately trying to hide. It was a habit that Rhem was never able to rid from him; that need to always look and act professional [i]every second of every day[/i]. Rhem looked up one more time at the Dane's throbbing erection, then he looked down at his own cock which was sticking up and throbbing as well. He moved his hands up and started caressing Chris' thighs. "Okay, I'm good now. We can continue." The mechanical arm slid forward and brought the thick, blunt dildo up against the dragon's tailhole, making the dragon huff and groan lightly. The dildo pressed firmly against it, and it slowly started to open up and stretch over the tip of the blunt dildo. With the tip in, the dildo continued to edge forward, pausing slightly as the dragon's anal ring met the first rib in the veiny dildo. The mechanical arm gave the dragon a few seconds to adjust before it gently pressed forward again, the dragon's tailhole stretching slowly over the rib before taking it in. It eased the dildo in deeper, and the second, then the third ribs in the dildo pushed into the dragon's stretched ass. As the last few centimeters of the thick dildo pushed into the dragon, the mechanical arm started slowly pistoning the dildo back and forth, letting the veiny ribs drive the little dragon's excitement. Each time a rib on the dildo popped into him, his cock would twitch and shoot pre onto his belly. With his body strapped down and legs spread, the green dragon was completely helpless as the mechanical device probed and fucked his stretched tailhole with the big dildo. The dildo pushed deeply into him time and again, thrusting away as the ribbed texture rubbed across his lubed tailhole. His belly started to bulge a bit each time the dildo pushed in, the large toy had him about stretched out to his limit. His cock twitched and throbbed freely, himself now fully erect and blushing as the dildo pounded away on him. The mechanical arm stopped for a few moments and started to slowly ease out of the little green dragon. It took the dildo away and stowed it underneath the table. The little dragon sighed in relief, his cock still throbbing and dribbling pre as he tried to relax. A moment later, the arm came back up with that little hose with the silicone tip again. It moved over to the dragon's ass, shooting warming lubricant all over his ass again. Then it poked the tip into him, shooting more lube all over his insides. After it pulled out, it paused and waited while the little dragon huffed and moaned from the stimulation; the tingling and warming from the lube making his cock twitch and shoot pre straight past his head. The arm then moved the hose up just a bit more and shot the warming lubricant all over the dragon's balls and cock. The little dragon squealed in delight, his entire body shaking as his cock throbbed and pulsed, shooting more pre all over his chest. It was all he could do as the tingling and warmth spread throughout his balls and cock, himself trying to dry-hump at the air as his cock tingled and spurt pre across his snout. Rhem noticed a drop of precum from Chris' cock dripped off and landed on the tip of his muzzle. He quietly licked it up then patted Chris on the side, "Okay boys, he's stretched and lubed. Are we ready for the second phase of this?" Everyone around the room repsonded with muted mumbles that sounded vaguely positive. They were definitely a bit distracted by the display. Good. There was no rule that said people should hate their work. "Okay then", the panda announced, "let's move on with the next phase then. Let's open up those bay doors to the lab and give the signal to the handlers outside." On the far side of the lab, the big cargo doors opened up, giving about ten meters clearance horizontally, by four meters vertically. The bright daylight penetrated the lab, lighting up the vast room much better than the lights had been. A rush of fresh air blew into the lab, with the quaint scent of trees, exotic flowers, and a salty breeze coming in off the ocean. After a few minutes, the panda started to get impatient. He looked over to one of the technicians, "Hey. What's the holdup?" The tech touched a button on his console and whispered. After a few seconds he nodded and spoke back, "Handler's on her way now. There was a bit of a delay but it's been fixed now." Finally after another minute, everyone in the observation room could hear a noise echoing in from outside. [i]clomp clomp clomp clomp[/i]... Rhem grinned from ear to ear. His erection had died down for now, but he was sure it was about to come back up. He looked up and licked Chris' ballsac again for good luck...or for being a horny bastard, it really didn't matter. [i]clomp clomp clomp clomp[/i]... The panda's cock twitched and leaked a bit of pre, which dribbled down his shaft, down his balls, and dripped onto the floor below. He wasn't hard, but he was certainly feeling excited anyway. The noise was getting closer very quickly. [i]clomp clomp clomp clomp clomp clomp clomp clomp[/i]...
