My stories are copyrighted, so NO takee! This story was 'inspired' by a lovely series of drawings I saw on one of the Furry sites some time ago, they just cried out as the basis for a story. I almost titled it "Close Encounters of the Worst Kind", but decided to save that title for another story!

Spare Parts

By William W. Kelso

The huge ship shuddered, alarms sounding, and with another shudder slipped back into normal space. Diagnostics confirmed what the ships central control node already knew, engine failure. Two of the main drive components had finally given out after untold eons of service. They could no longer perform their main function, so others would have to be found to replace them. But they would not be discarded, the ship wasted nothing, another use would be found for their basic components. It was sheer bad luck two had failed almost simultaneously, the ship could have continued it voyage despite the loss of one, but not two. Replacements would have to be found.

The ship was not familiar with this section of space, it was largely unexplored as it was isolated and most of the planets were little more than barren rocks, and the systems were quite a distance apart, even by universal standards. So the ship was pleasantly surprised; if it could truly feel such emotions, when a probe returned fairly shortly; about twenty years later, with scans of a planet with a civilization in the early technical stages. Initial reports indicated the parts needed would be easily acquirable. The ship set course for the nearby system, and at normal drive would arrive in approx. ten years, which to the ship was rather quickly. It did not measure time in hours, but eons. It was so old it did not remember its true origins.

The ship resembled a huge oblong similar to a football more than anything else, and it was a living being designed by its makers to live in space, and be self repairing and self sustaining. It was a 'deep space probe', and had no real 'crew' even though all of its components were alive, in one form or another. The ships technology was based on organic biology, not mineral or other non-living matter as was more common. It had been dispatched to explore, find, and send back reports of planets and other things of use to its makers. It continued to dispatch messenger drones to the indicated coordinates at regular intervals, but had not received a reply in longer then it could remember. But it had a job to do, and continued to perform it. But now it needed to rest and repair its engines. It would also replenish other needed staples such as water and various trace gases and other nutrients. The planet recently detected was ideal for what the ship needed, it was surprisingly rich, not the usual almost barren rock.

It entered into a stable orbit out of range of any scanning systems the civilization might have, having been programmed to avoid contact with alien races if possible. It doubted this civilization had any scanners capable of penetrating its shields, but still, it had not survived for so long by taking any chances. It had no real defenses, and if attacked its only option was to run, but without its main engines its speed would be severely limited to only standard drive. As soon as orbit was established specialized probes were dispatched to obtain the necessary components and raw materials needed. Some collected huge amounts of water from the planets oceans; the water, salt, and minerals it contained being very welcome as the ships supply of liquids had been recycled so many times it was past time for replacement. As soon as the new water entered the ships 'circulatory' system the ship felt 'better', more energized, as the old over used and worn out liquids were voided into space. Others gathered various materials, living and non-living, which were processed and utilized, or stored for later use.

When the probes with the main 'components' arrived the ship very carefully examined each and every prospect, and finally settled on four. Two would be adapted and utilized right away; the other two would be put in long term storage as 'spare' parts. The rejects would be reduced to their basic components and used as deemed fit. They were placed in 'pods', infected with biological nanites, and dissolved, the fluid being drained into storage tanks. Though aware of what was happening to them they suffered no pain, and in a strange way didn't really 'die' as they understood the term as the 'solution' they became was still living, and it remained aware and cognizant, it's 'mind' a composite of many different entities, but that was of no importance to the ship.

The two animals selected to become the engines new components were run through a long and extensive series of tests to determine how they could best be of use. The ships engines literally ran off of psychic energy, provided by extreme physical and/or mental stimulation of the engine's main drive components, which were living beings. It did not matter much if they were sapient or not, but intelligence did seem to increase the levels of stimulation response. So the ship was quite 'pleased' with the new components as they met all the required criteria quite nicely. The next series of tests would determine which types of stimulation would produce the highest levels of physical and psychic response.

Further tests indicated the animals did not utilize their entire brain capacity, and much of what they did use was sub-conscious and/or instinct. This was something of a disappointment as animals that had higher amounts of upper brain function were the most useful. Some even became new control units for the ship to replace old or 'ailing' ones. These animals, though sentient, did not meet those criteria. So other methods of stimulation were applied other then purely mental, and the ship soon found exactly what it was looking for, in fact was almost 'shocked' by the incredible amount of power the rather basic stimulation produced. The readings were almost off the scales, and the ship realized it had found exactly what it needed. The new drive components would be far superior to any the ship could remember having used in its long past. The fact the animals were also easily susceptible to physical and genetic modifications were also a major bonus as physical modifications would increase the power production rate considerably. Further analysis and tests were performed, and then the preparations began for the new components to be adapted to their new function.

Jimmy was terrified; he didn't know what was going on. One minute he had been on the way home from work, and had run into that big bully Marvin, who had been giving him a hard time as usual as making his life miserable seemed to be the much larger boys favorite pastime. Then everything had gone dark, and he'd woken up here, wherever 'here' was. He had a feeling he wasn't even on earth anymore, he knew it instinctively. Nothing like this existed on earth. He'd woken up butt naked in some sort of weird cage, and Marvin was there too, the bully just as scared as he was. When he'd woken up there had been other people as well, men and women, as well as some animals, all in the same clear 'cages' of some kind. Then to his horror the others had, one by one, began to melt. They had; screaming and begging, literally dissolved into piles of what looked like grayish pudding, then had been drained away through holes in the floors of the cages. He kept waiting for it to happen to him every time he was put back in the cage after having been 'tested' and experimented on, but so far had been spared.

Finally only he, Marvin, and two other guys he didn't know, were left. The other two had been taken away by the weird living 'robot' things again, never to return. And now the robots had come for him and Marvin again, removing them from the cages, the clear barrier that looked and felt like glass just disappearing. He guessed it was some sort of force field like in the space movies. He'd given up trying to resist, the robots; or whatever the hell they were, were too damn strong. He was a little less terrified then before as they never really hurt him, in fact some of the tests had been horribly pleasurable, such as when they milked his cock and made him orgasm. For some reason that had seemed to 'excite' the robots, and they had done it until he'd run out of cum and the ejaculations became dry, and painful. When he started screaming in pain they had seemed to realize he'd reached his limit and stopped. But they'd done it again a few more times over the next few days, the orgasms even more incredibly intense and pleasurable each time almost as if they were learning how to increase the pleasure on purpose, which he thought was kind weird and sick, but it did feel good, at least his body thought so even if his mind was less than thrilled.

He and Marvin were taken through the icky looking corridors of the ship, or cave, or wherever they were; the corridors or tunnels looked like the insides of intestines or something. They were gray, red, pink, dark purple, or a blend of those colors, and looked wet and slick, and it was humid. The 'hatches' they went through opened and closed like sphincters with slurping sounds. It was gross, like being in somebody's butt. He giggled a little hysterically as he remembered a funny Beavis and Butthead video he's seen once, that's what the robots are, buttnoids, he thought, and we're in some aliens butt! Marvin heard him giggling and looked at him like he was loony. The robots didn't care if they talked or not and Marvin had apologized for being such a jerk before, and they were friends now, brought together by their mutual fears, each taking some comfort in the other presence. When he explained Marvin laughed too, they were both Beavis and Butthead fans so Marvin knew what he meant.

He had been taken this way many times before, but suddenly realized the robots had taken a left instead of a right, they should have gone right if they were going to the 'testing' chambers. So it would appear they were being taken somewhere else this time, which was reason to be worried. They were taken to a new chamber he hadn't seen before, and there were new cages similar to the ones they'd been in before, but as they got closer he realized they were very different as well, and started to panic, Marvin as well. The other cages had been smooth and slick on the inside, these had protrusions, and as they approached what looked like tentacles came snaking down from the ceilings and up from the floors, and he had the horrible feeling the 'cages' were alive somehow, and waiting for him. Despite his frantic struggles and begging he was pushed into a cage and some of the 'tentacles' grabbed him. The whole time he'd been here the robot things had never said a word or made a sound, in fact the only sounds had been screams and begging from himself and the other people and animals, or a kind of distant pulsing sound like a giant heartbeat at times. He could hear that pulse now, slow and regular, almost soothing.

The tentacles grabbed his wrists and ankles and held him suspended in the center of the cage, and the same thing happened to Marvin, the larger anthro struggling desperately. The tips of the tentacles flattened into narrow 'straps' as they wrapped around their ankles and wrists, easily keeping them secured. They were soft and rubbery, and didn't bind or hurt, but were incredibly strong, and he knew he couldn't get loose from prior experience, so just hung helplessly suspended, whimpering. Once secured 'glass' walls appeared sealing the cages, and he yelped as he suddenly felt something warm brushing against his feet, and looking down realized the cages were filling with some sort of thick liquid. It looked like water, but didn't really feel wet; it felt more like some sort of oil or gel. It was pleasantly warm, and as it slowly rose up his body it tingled where it touched his fur. Then some sort of new appendages lowered from outside the 'glass' barriers of the cages, and pushed through them causing the 'glass' to ripple like it was water or something instead of a solid. Jimmy stared at the end of the nearest appendage; it looked like a dick, and the tip opened up into a funnel like shape, and he could see Marvin turning his head trying to avoid the thing as it neared his face.

___________

The ships engineering control node monitored the drive component pods as the new 'parts' were installed. It would be some time before they would be ready for use as the required modifications had to be made first, but first they needed to be put in life support suspension. First they were immobilized, oxygen & nutrient supply umbilical's would be attached, and then they were sealed in the pods as an insulating and nutrient bath was injected until the pods were full. It was similar in some ways to an amniotic solution as it would help to provide them with nutrients they needed, and would also act as a barrier against infection and contained antibodies to help keep them healthy. It would be quite similar to being in a womb. As the fluid levels rose the life support umbilical's were inserted into to the pods. They were specially designed to provide the components with oxygen, a nutritious paste, as well as part of the stimulations which would help provide maximum power output as it had been determined that oral stimulation was also beneficial when applied simultaneously with the main stimulations. The females had responded better to the oral stimulation, but the males produced more constant power overall from the main stimulations, so had been chosen over the males.

__________

Jimmy watched as the thing that looked like a dick with a funnel on the end came closer to his muzzle, the one in Marvin's cage had already clamped over his friends muzzle and the other cage was full of the fluid now and the fluid in his was up to his armpits, the warm tingling getting more intense and pleasurable. And to his horror the stump looking thing in Marvin's cage had sprouted more tentacles that had attached themselves to his friend's nipples, and from the way Marvin was acting it must hurt or something, and it was growing what looked like a cock! A big thick one; that was clearly going to soon be going up his friend's rear! OMG, he thought, it's going to sodomize us; it's true, we're going to be probed!! But what the HELL for? He was unable to see the same kind of 'trunk' behind him also sprouting tentacles; as well as another rather large 'cock', moving closer as it prepared to attach itself to him for life support and assimilation, which had already started on the other component.

Once the life support umbilical had been secured around the first components oral orifice tendrils were inserted in to the nasal passages and mouth of the component to attach to its nerve endings there and monitor its condition; and also to help with stimulation, as a phallus shaped organ was slid into the components mouth and partially down its throat. It would inject all the nutrients the component required in a simulation of oral sexual coupling, the phallus injecting food in spurts similar to those of reproductive fluids being injected my a male animals penis. For some reason this produced a fair amount of desirable stimulation. Shortly thereafter the connection was made to the second component as well, and the main nerve nexuses stimulation probes began to move into place as well. The first component's two upper nerve nexus stimulation probes had already attached themselves and began to extrude filaments for assimilation and adaptation as they merged with the component to become part of it. The process could be painful at first, at least until the components nervous system was integrated and modified to provide a maximum of pleasure stimulation.

__________

Jimmy squealed in pain, bucking helplessly, as tentacles attached themselves to his nipples and naval, and he could feel them actually growing into his body, and it stung and hurt like hell. He whimpered and tried to bite the thing sliding in and out of his mouth and throat, then froze as he felt something push at, then penetrate his asshole! 'NGGMMFF! AHHHUGH!' he moaned as it slid in deeper and deeper. He could feel it inside of him, worming its way deeply into his bowels. Suddenly he gasped, and went limp in shock as the pain turned into pleasure, and he felt himself getting an erection, and soon it was rock hard and aching.

__________

The first component had already achieved full upper nexus attachment, and now two more tendrils were extruded from the main assimilation trunk to attach to the part of the animals genitals containing the sperm producing organs. The animal was already experiencing a sense of pleasurable; steadily increasing, sexual arousal; its injection organ extended and erect, and as its sexual organs were assimilated that pleasure would increase proportionately. The anal probe had already achieved maximum required penetration, and was already extending fine villi to merge with the nerves in the components intestinal tract and other lower body, much as the three attached to its upper body and head were doing the same. Soon the ships engineering control mode would feel everything the component did, and would be able to minutely control everything it felt as the component became a living part of the engine. The anal probe would also simulate an anal sexual coupling with another male as this would also increase the components power output considerably, so was designed to thrust constantly at varying speeds to stimulate the desired organs and nerves. The main probe would also modify the components digestive tract and other internal organs to make it more efficient in the absorption of nutrients and produce fewer waste products.

Slowly the main assimilation trunks merged more and more with the components, the anal penetration and assimilation spreading, the trunks beginning to absorb the components extremities as the animals were pulled into a permanent 'embrace' with the ships engines; literally becaming part of it, as the bindings around their arms and legs also merged with their bodies. The first components penis and testicles had already started to undergo noticeable enlargement; which was required in order to increase power output, and another tentacle with a cup on the end was being extruded to complete the sexual organs assimilation. The second component was also responding well, and assimilation and stimulation tendrils were now extended to attach to its sperm and semen producing organs as well. The sexual arousal and pleasure the components were experiencing was increasingly steadily, but actual ejaculation had not yet been allowed. To promote more rapid genital growth this release of ejaculate fluids would be denied for quite some time.

The second components testicles having been successfully assimilated another tentacle was extruded and the cup sealed over the head of its penis as well. As soon as the cup was secure a tube was inserted into the urethra slit, pushed in to the testicles, and as it reached the sperm reservoirs the tip of the tentacle split, each new tip entering each testicle and attaching to the components nerve endings, in addition to the tendrils inserted directly into the sperm producing organs having penetrated the scrotum. The cup created an airtight seal around the head of the sexual organ, and it would also provide sexual stimulation to the sensitive head of the organ. At this point the increase in production of semen and sperm increased dramatically as intended, and the injection organ and testicles began to enlarge fairly rapidly. The specialized assimilation attachments were now producing intense sexual arousal and stimulation identical to what the animal would feel during coupling with a female; only many times increased, the two new components now at an incredibly intense level of sexual arousal and pleasure as their sexual organs underwent steady enlargement. Full sexual assimilation had been achieved, now there only remained for the growth stage to reach completion, at which point the components would be brought on line to perform their intended purpose.

__________

Jimmy squealed and bucked as much as he could as he felt his testicles suddenly penetrated, and though it hurt at first the pain quickly became intense pleasure, and he could feel his balls churning and pulsing. He moaned and thrust as something soft and smooth swallowed the head of his cock, then gave a muffled yelp as something slid into, and down, the shaft of his cock, and groaned as he felt the intrusion enter his balls, which became even more sensitive, pulsating and starting to swell even faster. He grunted and thrust, desperately trying to cum, to reach orgasm, his aching cock and balls quivering with their every growing need. He'd never been with a woman, but somehow he knew this must be what it was like. It's fucking me, he realized, but WHY? Ohhhh, it feels so good, so wonderful!! Groaning he thrust desperately even as he tired to remain lucid, but as the pleasure; and horrible need, increased he sank more and more into a kind of trance of sexual bliss, his only concern the incredible pleasure and his desperate need to CUM!

_________

The ship monitored the steady growth of the components sexual organs, their increasing size and weight easily supported by the thick life support gel that filled the components nodules. The penis and testes swelled steadily, growing to sizes that amazed even the ships intelligence nodes, the ability of the animals to undergo such modification to their sexual organs was truly amazing; it far exceeded the modifications of any previous components.

__________

Jimmy floated in a fog of near sexual euphoria. He'd never known such pleasure before; this was even better then jacking off! Much better! Instead of biting at the; what he now thought of as a, cock in his mouth he eagerly sucked and tongued it, being rewarded with blasts of salty 'cum', even as the 'cock' in his ass kept 'sodomizing' him, thrusting nonstop, only varying its speed. His own cock ached and throbbed; so hard it was painful, his balls pulsing with lust, he needed to CUM! Though rendered almost comatose from sexual pleasure he still managed to come around enough to open his eyes for short periods, and was horrified and shocked by what he saw. It looked like Marvin was completely out of it, and his cock and balls had grown immensely, were now as large as his body, and Jimmy could see them visible pulsing and throbbing. With a whimper of pleasure he craned his head and looked down at himself and gave a chocking sob, his own cock and balls were huge too, not as huge as Marvin's, but his cock was still over two feet long, his aching balls the size of cantaloupes. And he could see that where the tentacles were attached to his and Marvin's bodies they had grown into them, and he realized with horror they were part of them now! Then the 'cock' in his ass sped up as it kept 'fucking' him, and with a moan he sank back into sexual bliss, needing to cum so very badly, the need agonizing now, his cock throbbing and aching. It would be one of his last returns to coherent awareness.

__________

The components were almost ready to go on line, the growth of the second ones sexual organs had begun somewhat later then the firsts, but both had to reach their full potential before being brought on line as the growth would stop once they were allowed to reach sexual release. Finally both components were ready, their sexual organs now far larger than their greatly modified bodies, the rest of their bodies now being merely part of the life support system for the huge straining sexual organs and their prostates. The immense shafts throbbed and pulsed visibly, the skin of the scrotums taught from the swollen straining testicles they contained, each one producing sperm and other sexual fluids at hundreds of times their normal rate, but once they reached full modification and went 'on-line' that rate would decrease as the cum they produced would be recycled, pumped directly back into their testicles.

Having reached maximum sustainable power levels the stimulation was increased to a level tenfold above what had been applied so far, and the inhibitors preventing orgasm and ejaculation were lessened and simultaneously each of the components climaxed violently, huge pulses of cum being blasted into the tubes inserted down their penile shafts and into their testicles, to be returned directly to the testes for 'recycling', the airtight cups stimulating the heads of their penises preventing any leakage.

Both components arched and bucked as intensely agonizing sexual pleasure exploded through their nerve endings and brains as they orgasmed, thus producing the intense psychic stimulation that would power the ships engines. Approx one minute later they both climaxed again as stimulation was increased, then again every minute for an hour and ten minutes, muffled/gurgling squeals and screams of ecstasy coming from the writhing components. Then the orgasm's began to occur every fifty seconds for an hour, then every forty-five seconds, every forty, and finally several hours later stimulation was increased to maximum, and they began to orgasm nonstop, their huge penis's pulsing, balls straining throbbing, as they entered into full power mode. A minute later the ship engaged its main drive and disappeared from normal space. By then their only awareness was one of total sexual euphoria, pleasure beyond description, a Heaven and Hell of unending ecstasy.

__________

Jimmy came too once, very briefly, even as the unbearable pleasure kept increasing, and managing to open his eyes didn't realize what he was seeing at first, didn't recognize the huge throbbing shaft of flesh in front of him for what it was. He moaned as the 'penis' in his mouth slid back and forth, thick sweet 'cum' spurting down his throat at regular intervals, the other 'cock' in his ass thrusting so pleasurably, his own cock and balls feeling like they were exploding as they ejaculated again and again with waves of excruciating pleasure, the time between orgasms steadily becoming shorter, the pleasure even more intense with every throb and spurt of cum. Moaning, he watched as the tube attached to the end of the thing visibly swelled in pulses as fluid was pumped through it, and lowering his gaze gave a muffled moan of shock and horror as he realized it was his penis and balls, now even larger than the rest of his body, and turning his head saw Marvin's was even larger. He gave a final moan of confusion and despair as to why this horrible thing had been done to him, and then his eyes rolled up in his head as he began to orgasm nonstop, and he returned to the bliss of total sexual euphoria, no longer aware of anything but the pleasure.

__________

Over time the two main drive components; which were now a part of the ship, would continue to be absorbed until only the sexual organs and nervous systems, including the brains, remained. The life expectancy of such a component was in excess of 300,000-5000,000 earth years, and when they finally failed they would be dissolved and their components used for the further benefit of the ship and its purpose. Then the two other animals would be modified into new drive components. The ship was quite 'happy' with its new parts; they were proving to be top quality.

The End
