The Experiment

The doctor stood at his computer terminal, the blue glow of the monitor lighting his features. He was a 5' 11" grey squirrel, in his mid twenties. He wore a pair of glasses, and had an off-white labcoat on, draping over an athletic body. An odd bulge ran up the front of the coat, pulling it tight to his shoulders. His brown eyes scanned the screen in front of him gleefully. He had almost done it! Soon, he would complete his last, greatest biological breakthrough. He had long been interested, some would say obsessed, with the male sex organs. How they worked, thier size, their efficiency. When he had tested certain formulas on an unknowing patient, the medical society had cast him out, even though the person had had no complaints; who would complain about a 15" penis that came almost steadily without stopping from the slightest touch, and that could keep doing it at will, without any negative side effects? But the other doctors had deemed him too insane for conducting such a test without authorization, and had banned him from experimenting on others, or from conducting medical work on anyone else. That hadn't stopped him, though. He still had his own body to work with, and due to several saavy investments, had quite a fortune to work with. He had had this laboratory constructed, and had begun his research.

First, he had addressed the sensitivity of the organ, deeming it much too weak. A male should be in complete ecstacy for the brief time that he came, not just barely feeling it. He had used a combination of super computer simulations and careful sample cell tests to enhance and alter the nerve cells in a subject so that while cumming, the entire body would experience the pleasure, not just the man's cock. He had immediately tested it on himself as soon as he had perfected it, completely ignoring the fact that he had broken a code that could be used to restore damaged nerves and enhance brain function; some things were just more important. It had worked just as he wanted it to, except that the mind numbing orgasms only lasted for a few seconds. Which had given him his next project. Why not increase the length of the orgasms, so as to prolong the effects of the previous formula? He had quickly started on this next idea, and settled on nanotech as a way of safely altering the physical makeup of his balls so as to make them produce more cum, for an extended period. This too he had immediately used on himself, with the result that his bedroom had begun to have a strange smell to it and he had been forced to install a drain in the floor of his bathroom. Thinking of that particular enhancement, he reached down to rub at his balls, which always felt as if he needed to drain them now. They were each the size of a softball, and stretched the skin of his sac tightly. He rubbed them eagerly, forgetting for a moment what he was doing.

"Now, now... I can do this afterwards; first to complete my greatest experiment." He reluctantly returned to typing on the keyboard, thinking as he did of the other marvels that he had created. His cock was always hard now; he had heard a thousand times that it was a problem, or that it was unhealthy, but he had created a formula that just made it pleasant. Unconciously, he thrust his hips softly; the head of his shaft brushing up against his collarbone. That too had been a formula he had created. He had used the nanobots to copy cells in his cock's length, increasing it's size and girth. It had been a measly 8" long and two inches wide; now it was a 15" long and almost 3" wide along the entire length, and could get even larger. He humped gently at his labcoat, stroking the head of his shaft faster and faster, starting to lose his train of thought. Suddenly, he forced himself to stop, breathing heavily. "I have to finish first." he said to his cock, which throbbed at him eagerly, urging him to forget again and go relieve himself. "No, not yet!" he muttered, then returned doggedly to his typing.

As he worked, he reminisced on the other improvements he had made: he had increased his stamina to the point where he only came if he wanted to; he had added a special series of valves and heart-like organs to his shaft that kept it stiff and made it throb steadily like a beating heart; he had even developed a colony of nanobots within his body whose sole purpose was to multiply the amount of semen and sperm his body created, allowing him to produce gallons of cum at a time. As these thing ran through his mind, the front of his labcoat began to get wet with precum; he didn't bother with clothes much anymore, they tended to get in the way when he needed to satisfy himself. He only wore the labcoat in the lab, to keep the delicate machinery from getting sticky. Even so, he found himself resting his cheek against his throbbing shaft's head, licking it through the coat. It sent waves of pleasure so intense through him, he felt his head spinning, and it swelled even further, pushing through the neck of his coat and pulsing in front of his eyes, blocking his view of the screen. For a moment, he couldn't think of anything but cumming; that hot pulsing feeling ripping through his senses and leaving him unable to do anything but stroke and gasp and cum and cum and...

With a supreme effort, he stopped working at himself; he had started sucking on the monstrous rod, and had opened his labcoat to pump his hands along the pulsing length, working towards a good cumshot. But if he did that, his computations would be lost, and he would never reach his ultimate goal. You see, he had discovered the one fatal flaw in the male genitialia and intended to correct it. Being curious and interested in the male sex organ, he had examined many specimens in his search for a way to improve on them. He had noticed a trend; the males with the hardest cocks were also the smallest comparitively, and depended on blood pressure to get erect. On the other hand, the truly huge males tended to have cocks made of muscle, but couldn't use them for long; they were too heavy and sensitive, and would cum too soon, then retract. He had solved the hardness problem with the valves, but hadn't been able to endow himself with a truly huge shaft. The biggest he could support comfortably was a 10' rod, with 12" balls. Past that, the weight of the organs would make them pull free under their own weight. He winced at the thought. Also, trying to keep such an organ hard with blood pressure tended to use more blood than the body could give, causing unconciousness and blood pressure related problems, like heart failure and burst arteries. So he had decided to use a muscular approach. But then, he still had weight problems... until it came to him, as he was... relieving himself, and was feeling around the base of his shaft. If it was connected with some kind of support... he had immediately begun designing a cartilage skeleton for his cock,using a shape similar to what a snake had, with a spine running along the top side, and ribs arching around the shaft, stopping near the tube running underneath.

He had realised that this form would allow him almost unlimited increase, but still wanted some sort of mobility, so he had begun alteration plans for the lower part of his body as well. He had programmed increases in the musculature of his legs, hips, rump and feet, as well as increasing the strength of the tendons and joints. He had also increased the size and spread of his soles, so as to give added support to the final result. He had felt a horny flush run through him as he looked at the final result on the screen; he would be able to double or even triple the original specs! He imagined himself with a 20 or 30 foot long cock, with 3 foot wide balls, and had jacked off for hours, thinking how good it would feel... and what an accomplishment it would be, of course. Now he stood in front of his monitor, trying to stop sucking himself long enough to finish inputting the final algorythms... He pushed his cock onto his shoudler, resting his cheek against it and continued to type. Finally, the final computation was finished. He grinned at the 'Computations Accepted.' quote on the screen. He could move to the nanotech application room now, and soon he would have his wish granted. Gripping his cock and softly stroking at it, he walked into the room, his balls bouncing on his thighs.

As he entered the room, he dropped his labcoat to the floor and began stroking himself in earnest; this room was designed to deal with the sudden urges that came over him while he was working, and had several wide drains in the floor. Climbing on the padded (and waterproof) table top, he lay on his back, holding his cock up so it pointed to the ceiling and working it with both hands. A cascade of precum flowed down it's pulsing length, quickly slickening up it's sides, until he was able to speed up, his hands flying over the throbbing length. His entire body felt as if it were pulsing in time with the massive rod, which had reached it's maximum length of 18"; he kept it so hard so often that it had actually gained in length. He felt the steady flow of pre washing over his hips; it felt like a warm, sticky shower, and he groaned, curling his feet up and gripping at his balls with his toes. He waited for one of his mistakes to kick in; one of his favorite mistakes. When he stroked himself, but didn't allow himself to cum, he eventually reached a point where it felt as if he were coming anyway, with the full force of an orgasm pulsing through his body, and jets of precum spurting from his cock. He watched and groaned as his cock pulsed harder and harder, shooting jets of clear fluid around the room, quickly coating his body. The first shock of false orgasm rushed through him, and he yelled wordlessly, his body going stiff with pleasure. When he came, every nerve in his body sent pleasure messages to his brain, swamping all other sensation. He humped at his grasping fingers, thrusting hard as he shook from head to toe with the force of his almost coming. 'Now the second mistake should kick in..." He grunted as the base of his shaft, filled to bursting with held back cum, began to expand outward, quickly spreading up the length of his shaft. The sensation was indesrcibable and he grunted wildly as his fingers were forced apart until they were resting on opposite sides of his now 12" wide shaft. The bulging increased, moving slowly up the massive shaft, until it reached the head, where it stopped. The doctor wanted to cum so bad; but it felt so good to hold it! He had held himself like this until his shaft had actually trippled in girth once; then he had cum for eight hours straight, the feedback of pleasure too much for him to halt on his own. Feeling the pressure building, and watching the massive veins in his cock swelling, he decided he would have time to try this again after the operation, and relaxed his last bit of resistance.

The geyser of cum flooding from his shaft reached the ceiling easily, and splashed around the room, quickly overflowing all but one drain on the far side of the room. The clear plexiglass windows to the room were coated in a spray of cum, looking like someone was pouring milk down them. The table became slippery, and the doctor squirmed around eagerly, drenched in cum. He worked his tongue out of his mouth, lapping up the sweet rain, and squeezed with his muscular toes at his balls, urging them on. They swelled and pulsed underneath his feet, filling then spewing thier contents to the sky. After almost an hour of cumming, his shaft slowly began to shrink, then the spout of cum trailed off, leaving the doctor panting happily. "And this is why I needed to do these experiments." he said to the room. He gripped his still hard, still ready shaft, then began stroking himself again. "I can cum like that over and over!" he panted eagerly, working his paws faster. "The same amounts! Again and again!" he pulled himself into a sitting position, working his arms around the throbbing shaft. "I... can do it... *grunt!* as man...ahhh!... many times... as... as I want...!" The doctor reached up and gripped the head of his shaft, pressing two fingers into the wide slit at the top and working them in and out. Cum immediately began to boil from it, and he worked another finger, then two into his slit, cum now spurting crazily from the partially blocked opening. "Huuhh! Huunngh!" pressing wildly, he managed to get his entire hand into the head of his shaft, and began trying to work his wrist in, cumming furiously. The small thing couldn't handle it though, and he was forced to pull his hand free and let his cum shoot out, drenching him again. Finally, he decided to let the operation progress, then return to his fun; it would be much more interesting afterwards, anyway!

* * * * * * * * * *

The doctor didn't bother washing off the cum; if this operation was anything like the last one, there would be a lot more before it finished. He reached to one side of the tabletop, then pulled out a screen that had been concealed under the edge. Lifting the glass plate protecting the keys, he hit the activation sequence. Panels in the roof slid open and robotic arms extened from the ceiling. The doctor felt his balls draw up in excitement, excitement that just became heightened by two of the arms gripping his ankles and pulling his legs apart and down. Straps extended from the table restraining him from moving; the last treatment he had used on himself had felt so good, he had nearly broken one of the arms working it against himself. Two more arms gripped his shaft, which throbbed, then held it upright. A fifth arm lowered, holding the end of a wide tube, and pressed it against, and into, the head of his now throbbing shaft. He watched with rising arousal as the arm, tube and all, pressed itself into his cock, sliding down it's length. The other two arms holding his shaft worked at it carefully, helping the fifth arm to go deeper, and making the doctor squirm eagerly, thrusting his hips as best he could. The arm reached the base of his shaft, then shifted a bit and continued up into his body, making him shiver in pleasure. He held back with all his might, though he could no longer stop himself from working his hips, shifting the tube and arm in and out of his cockhead. Precum spurted out around the arm, and he closed his eyes, concentrating on the sensations.

After what seemed an eternity, the arm stopped moving in, and he watched a silvery flow of liquid move down the length of the tube; nanobots. They would carry out the conversion of his sex organ and some of the other changes as well. He jumped as another arm lowered, then winced in surprise as it began pushing itself into his rear, pulling another tube behind it. "This must be the... other nanobots...uuunnghh!" Grunting and squirming he watched the arm slid itself several feet into his rear; he shifted his hips, thrusting at the arm deep in his cock, and felt a bit of answering pleasure from his rear as well. "Huuunn! I might need to investigate this further!" He worked at both arms, groaning and trying to wait for the nanobots to begin. A sudden rush of cum shot from the head of his shaft, and then his balls began to expand. They grew and grew, until they overlapped his thighs, which he saw were beginning to grow as well. He grunted and thrust harder, feeling each thrust gaining in strength as his legs and feet grew stronger. His ass muscles gripped at the arm pushed in between them, pulling it in deeper. Concentrating, the doctor was able to begin pulling and pushing the arm in and out of his ass using just his muscles! He started them to stroking him deeply, grunting in pleasure and pushing his hips forward harder, straining the straps holding him down. Finally his cock began to change as well; the veins lining it grew huge, and branched out under the skin until the entire length was webbed with them. It swelled in girth, expanding to two thirds the width of his altered hips, then began to change further. It took on a corded, muscular look, and stopped pulsing, instead swelling like a tightly flexed bicep.

The doctor threw his head back and, with a powerful thrust of his still growing hips, broke the restraints. He gripped his shaft with both hands and began working it at the arm still deeply embedded inside. Cum exploded from it's head, gouting more powerfully than even the doctor had thought possible, showering him in so much cum he had to hold his breath for a moment. It continued to grow, sliding along the arm until it was pressed against the ceiling, and then pushing into the hole the arm had come out of. The doctor humped at the hole in the roof, feeling his cock swallowing the arm right to where it was connected to the ceiling; a large metal ball joint. He grunted, pushing against this as well, and came even harder as it slid deeply into the head of his cock, slippery with his cum. The arm in his ass was being pulled deeper and deeper, until it began to whir and grind, extended as far as it could go. The squirrel's ass muscles pulled even harder, dislocating the arm from the ceiling and dragging it deeper still. The doctor leaned forward, raising his tail and gripping at his cock, humping into the ceiling, as the arm was drawn right up to the ball joint into his ass, where it strained to go further. His huge feet splayed powerfully on the tabletop as he stood, his body still changing. THe ball joint between his cheeks pressed in, then slid slowly into his ass, stretching him widely. Looking around eagerly, he saw the arms still attached to his cock and ankles, no longer able to restrict his movement at all. He pulled the two from his cock and then eased back from the one in the ceiling, a horny thought flooding his mind. His cock unflexed as he thought of what he wanted to do, and he was able to draw it down to where he could reach the head. Carefully, he pushed the straining arms into the head of his shaft, slowly flexing the muscle that was his cock until they were buried as deeply as the first one, then thrusting agianst them all at once. The sensation made him come again; this time he had to hold his breath even longer, his still swelling balls pumping gallons of cum at every spurt.

As he had done at during every procedure, the horny doctor made a mess of his room, but even more so now than ever before. When he walked from the room, pulling the last of the disconnected arms from the head of his shaft, he was still too horny to stop. He went to sit in his chair and stroke himself off again, but the feel of the chair against his ass made him even hornier. He began to rub his enlarged and muscular rump against the chair, then, balancing awkwardly on the seat, began working the back against his tailhole. Slowly, the altered muscles there grasped the back of the chair, drawing it up into his rear. He sat down on the seat eagerly, wondering how far it would go. He thrust down on it until he felt the floor under his rump, then looked back in surprise. The chairs legs slowly worked into him, and he rubbed at his ass hungrily, looking for something else to try. He eased the chair out again, then walked around the lab, looking at things and testing them. He finally came apon a long tube that was filled with electrical energy sparking from the insides; the source of the lab's power. He grinned widely, then set the head of his cock against it, feeling a jolt of electricity pass through him, which only made him hornier. Oozing percum, he thrust against the tube, which was both wider and longer than his new cock. "Which science will prove to be stronger, I wonder?" he said, then moaned as the head of his shaft began to expand.

He worked the tube slowly into his cockhead, thrusting wildly and rubbing at the thing with both hands. The tube was knocked free of it's connections, and the lights went out; only the flickering violet pulses of the energy tube lighting the scene. The doctor felt a steady wave of electricity flowing down his cock into his balls and hips; he gripped his balls with his feet, kneading them as he scooted forward with his hips, sliding the tube deeper. He came powerfully, but nothing but a trickle was able to escape past the tube which he continued to work in to his cockhead. Grunting, he stood, then thrust hard, sliding another two feet into his cock. It swelled mightly, as he came again, his balls growing also until the were brushing the ground. Again and again, he strained forward, until he finally worked the last few feet of the energy tube into his swollen cock. It glowed from inside with the tube's light, and pulsed so powerfully that the doctor began to lose conciousness. He felt one last overwhelmingly powerful orgasm build up...

When he woke up, the laboratory was gone. All around him, broken masonry and bent metal showed that some horrible accident had occurred. "What...?" he started to get up, but something was holding him down. He looked down, and stared in disbelief. His huge, erection lay there on the ground, easily twenty feet long and two feet wide, just like he had dreamed it would be! His enormously muscled legs, hips and feet were spreadeagled around his huge balls. He tried to rise, and was surprised at how easy it was, the massive shaft shifting easily at his command. this wasn't what had him staring though. He was staring at the violet glow that came from his cock, and the rippling electrical field that surounded it. He suddenly remembered his ill advised 'test', and groaned inwardly."It must have shattered! If I hadn't had those nanobots in me programed to create new cells, I would probably be dead!" He looked around, then resigned himself to walking to town, huge cock and all to ask for help, when the giant thing twitched then suddenly shrank to a much more manageable size; though it was still glowing and wreathed in lightning. "Better than nothing, I guess. I wonder what else I can do with this?" A wicked grin came to his face. "I can't wait to see what those fools on the medical board have to say about this!" Digging through the rubble until he found a torn labcoat, he walked off towards town, whistling.
