Experimentation
The lab itself loomed rather massively over him as he stood outside the main doors. The loose clothes and ratty shoes he wore only made him feel more uncomfortable. The appointment had been for noon and it was now 11:50. He still couldn't get up the nerve to actually walk inside yet.
He shook his head. He shouldn't have signed up for this. It was probably some silly ploy to run a placebo test on him. It certainly wouldn't be what they had suggested. But the lure of the flyer was just too much. He bit his bottom lip and walked inside.
The receptionist took down his name and information, running over the release forms and the medical information before telling him to report to the back room. It wasn't embarrassing enough to go over his complete medical and sexual history to some random lady, in the back room he discovered that he would have to strip.
The whole reason he was here in the first place was that he was unhappy with how he looked. Not that he was hideous, just built wrong. Thin arms, pudgy stomach, no real muscle definition anywhere. Just kind of a stick with legs... and body issues.
When next he found the garment he was directed to wear, he blushed intensely. The small latex thong-like thing barely covered his groin and left his backside completely exposed. It was intensely uncomfortable for him and the only relief was that there appeared to be no real human interaction involved in the whole experiment. He shivered in the metal table, wondering again what in gods name had driven him here in the first place.
He was directed to enter a small, cylindrical room. This, so the speaker from the control room said, was the Memetic Gel Saturation Unit. To him it appeared more like a glass tube that he was shifting uncomfortably in.
Slowly, the container began to fill with a thick, transparent, lumpy gel. It poured out steadily through tubes in the floor. It felt odd at first, sort of like clumps of Jell-O, but he grew accustomed to it. Wasn't much choice otherwise, after all. The gel continued to fill the cylinder, slowly oozing over his chest. A breathing apparatus was lowered into the container and he was instructed to place his over his mouth. He did so, blinking a little as the gel grew to cover his head completely.
Next, he could feel a tingle all over his body. This would be the mild electrical shock they were talking about. It was far from unpleasant, just more of an overall tingle. It would make his hair stand on end, if it wasn't saturated in the gel. The tingle ran through his body, making his muscles convulse a little and giving his spine a significant chill. The current slowly died away, the gel sinking downwards into a set of weak vacuum ports. He still felt tingly, his body not responding quite well. His legs and arms felt rubbery and numb. He managed to slink out of the cylinder, maneuvering over to the table he was directed to and laying down across it's surface.
His face poked through a cushioned ring, much like a massage chair, though he felt a little flush from having his backside so completely exposed. Wasn't much he could do though, his muscles felt extremely fatigued and it was hard enough just to lay peacefully, much less shift around. Another opening appeared to be placed where his groin was, letting the thong poke through. Considering the lack of motor skills, he was happy enough not to be laying on top of any sensitive bits.
His ears perked as he heard some movement behind him. Something rather large was maneuvering around behind him. The sound of metal against metal stopped as he felt something loom over him, the dark shadow covering the floor beneath him.
"Initiate injection sequence one." A rather mechanical voice stated above him. He felt something firm and rigid against the cleft of his rump. It took him a moment to realize it was also phallic shaped. His eyes went wide as he felt the tip of it press against his exposed ring. It slid in smoothly, parting the muscle and slipping deep within his body. He gasped at the feeling, the cool metal within him vibrating softly. He clenched around it reflexively, his body still too numb to move any other way.
The metal phallus began to slowly pump in and out of his backside, brushing and rubbing against his sensitive insides. He grunted and moaned, the skimpy latex thong stretching out as his own length began to grow erect. This continued for a only a minute or two before a spray of thick liquid shot deep within his bowels. He shuddered again, feeling it tingle within him.
Slowly the phallus drew out, followed by a mechanical click. The voice came over again.
"Initiate injection sequence two."
He was filled again with the metal shaft, pushing deep within his backside. His hips moved as much as they could against it. His body strained as his own erection throbbed between his legs. This wasn't exactly what he expected when he signed up, but so far he wasn't objecting. The metal cock pounded him harder this time, stimulating him now. He rocked back against it eagerly, shuddering as he felt his balls begin to draw upwards. The shaft plunged as deep as it could within him, letting loose with another stream of thick liquid as his own shaft erupted, spraying seed against the floor.
Again, the length drew out of him, leaving him panting. The voice buzzed to life once more.
"Initiate injection sequence three."
He felt something large and metal began to move him, rolling him over on the table. His eyes now facing upwards, he could see what had been ravishing him. At approximately eight feet in height, it appeared to be a large, robotic dragon. The curves were smooth enough to simulate flesh, but the glowing eyes and quite obviously metal sheen of it's body suggested it's origins were not organic. Why a dragon? He shivered as it drew over him. He barely had time to breathe before it thrust it's way roughly into him again, pushing even deeper into him now. He panted, his body tingling even more than in the tank as this strange robot pounded away at him.
He could feel the metal cock pushing and forcing it's way deeper into him, a slow mechanical whurr suggesting that the thing could extend. His own length began to respond again to the steady and brutal fucking, twitching within the sweat soaked confines of the latex brief. The robot's snout dipped downwards, lingering over his mouth. A thin, flexible, rubber tongue pushed past his lips, forcing open his mouth as the machine began to french him. The thrusting grew faster as the tongue snaked into his mouth, the porous material appearing to ooze it's own fluids down his throat. He gasped, suckling at the tongue as his hips bucked back against it once more. The metal cock within him twitched and fired another heavy load of fluid deep within his body. He panted into the thing's metal maw before it slowly drew away from him.
Slowly, he was rotated back to face down on the table, his bulging thong pressed back through the hole, giving him another shiver. The thing drew away as he was left alone for the moment, his body rumbling and his mind woozy.
The tingle he had been feeling expanded out over his body, feeling like every muscle was tensing at once. He took deep breaths reflexively, shuddering as he felt a heat rush into his arms and legs. His body rippled, his backside clenching tightly as the fire rushed from his tailbone to his skull. Suddenly, it faded and he was left panting and erect, pressed against the soft table. He lifted himself slowly, pushing up with his arms as he turned, facing a shiny slab of metal before him.
His body was sleek and toned. The fat had melted away from his thighs and belly. His arms had thickened a little and over all, he was looking pretty hot. He blushed at his own reflection, running a hand down over his smooth, flat belly. He shivered a little at the touch, his skin seeming extra sensitized. The flyer was right, he did look and feel a lot better, but this didn't seem as radical as they suggested.
"Initiate injection sequence four."
He barely had time to turn his head before the robotic dragon grasped him roughly once more. He struggled in surprise, shivering as he felt that metal cock press against his backside once more. A series of latex rings and mechanical arms grasped and restrained him, binding him against the things heavy body. He we left to stare at himself in the smooth metal as the thick length pushed within him once more.
His backside spread open easily, almost eagerly accepting the length. It seemed different now, though. The smooth metal was now rubberized, ridges along the length rubbed against his velvety insides, making him shudder. The robot forced it's length into his fully, pressing well beyond anything he had taken before. His toes curled as he heard the slow rush of air from behind him.
Within, he felt the length begin to thicken and expand, swelling up inside him. He bore down on it again, shuddering as it filled him completely, sealing him shut. The robot brought it's snout down once more, the rubber tongue forcing it's way back between his lips as he felt the steady rush of fluid into his belly.
The tongue slathered the inside of his mouth, oozing it's fluids into him once more as he was filed from both ends. His eyes rolled back into his skull as his whole body felt on fire once more. The robot tilted forward a little, lolling his head to watch as his body began to react to the treatment.
Slowly, he could see his chest begin to expand, swelling outward and widening. His pectorals began to tense, broadening and thickening as thick ropes of sinew formed beneath his flesh. His arms also followed suit, thickening out as his shoulders shifted to support the new muscle weight. His belly sunk in, tight ridges of muscle now visible, moving subtly with every breath. Broad slats of muscle filled out his thighs, his calves swelling up as well. He could feel the rush of new strength through his body, flexing against his restraints.
His hips twitched as he felt more changes beginning. His thighs began to slowly change shade. What was once healthy flesh began to grow icy blue, shimmering as flesh turned to tough, shiny hide. He head rolled back as his jaw began to lengthen, eyes shutting tight as his new snout began to take shape, his newly forked tongue flickering over his sharp, ivory teeth.
A growl raised from his throat as he bared down hard around the robot's length still buried within him. His groin began to tingle as well, the flimsy brief feeling tight around his waist. His eyes fell back to his reflection, seeing the swollen bulge that now rested between his legs. His balls had swollen huge, pushing out from either side of the thong, the skimpy latex barely covering his new monstrous sheath. With a sharp thrust the robot forced his hips forward, the jolt rending the skimpy thong.
Hanging free now, his sheath bobbed between his legs, the tip of an ebon cock already peaking from the opening. His balls swung between his legs, his clawed toes curling as he felt himself grow erect. Inch after meaty inch slid from his sheath, bobbing between his legs. He could feel the warmth of his own tip brushing against his firm abdomen, every inch glistening in the light. Along the sides, thick fleshy ridges expanded outwards, his newly formed length now drooling precum through the valleys of his belly.
The shaft within him slowly began to shrink, slipping smoothly back out of the well-abused passage. The robot continued to kiss him, thrusting it's tongue deep into his throat as he felt himself lowered. His new three toed feet touched the cool metal floor as he felt the robot draw back. The tongue left his snout as the robot buzzed to life once more.
"Initiate collection sequence."
The robot turned, lifting it's metallic tail to expose a tight, rubbery ring beneath. His mind already hormone-flooded, he dove forward, sinking his ebon shaft deep within the robot. His claws dug into it's metal hide as he began to thrust frantically. Pounding his hips against it's backside. It wasn't long before the rush poured over him, the intensity sending him into a roar as he pumped thick pint after pint of hot dragoncum deep within the confines of the robot. The robot provided more than enough suction to draw out the last of his seed before stepping away and letting him sink down to his feet once more.
He turned again to see his reflection, a huge, well-hung dragon now staring back at him. He licked his lips and smiled, cupping his balls gently with a purr.
Now that was more like it.
