A bear embarking on a long trip discovers his exact role on the vessel.

This was the first story I completed for last weekend's Splatterday Marathon. ChimpyEvans on FA suggested this one though it went off in some weird directions that I did not intend. Each time I do a Mechanophilic story I like it a little more.


A dull hum rang against the spartan walls of the old colony ship. The thrum of dozens of pods worked in tandem to protect the vessel's crew from the ravages of time. The ship was fairly self reliant, the astrogation system making constant, minute corrections to keep the cutting edge, drifting ark on target for the first interstellar landing, a modicum of atmosphere cycling through the ventilation systems, even dim lights glowed from recesses in the floor just in case someone were to wake up and need a path somewhere or another.

A quiet hiss cut through the relative emptiness announcing just that sort of guest to the cold of space. The mildly claustrophobic chamber released the gasses and chill which had kept his body suspended for the last 13 months then opened slowly. The process of waking up after a year of deeper-than-REM sleep wasn't exactly pleasant but after a few coughs, the ursine took his first full breath in weeks and groaned as he pushed himself onto his elbows.

A chime came from somewhere near his feet and he moved his head much slower than he meant to. His body was doing its best to catch up but it was still fogged with cold sleep and he felt like he was surrounded by gelatin resisting every motion. Still, he shift and pushed until he could sit up straight and look at the screen trying to get his attention.

Good afternoon, Mr Grey, it said in softly backlit letters. You have been asleep for 1 year(s), 27 day(s) and 16 hour(s). Your trip will end in approximately 7 year(s), 3 day(s) and 15 hour(s).

John nodded as if the computer had actually spoken to him, he appreciated the fact that they gave him that information; it made the disorienting sense of waking up as soon as he'd fallen asleep have more context. He read one groggily, rubbing his eyes to make sure the year's worth of sleep would let him focus.

You were awoken in accordance with your contract as a member of the ship's maintenance crew please follow the green lights to your workstation for further instructions. Your uniform is in a lit locker along the path. Thank you very much!

It was a very congenial spaceship. At least as far as inanimate objects go. He pushed himself once more and drifted into the air turning head over heels until he pressed his hands against the low ceiling and shifted to orient himself. Weightlessness was definitely out of his purview but he figured he was the only one awake and if he was only going to be up for a few hours, turning on the artificial gravity would be extraneous. So he aimed for the hall and pushed slowly, following the soft glow of the maintenance lights and flew through the corridor.

The bear's thick body bumped clumsily against the padded walls shifting and turning somewhat out of his control. by the time he reached the locker assigned to him he was starting to enjoy the sensation. The locker was small, scarcely enough to hold his uniform. He looked himself over, his black fur naked save for a tight pair of bulging underwear, his thick frame obviously built for planetside machismo than weightless dexterity. He rather liked his body. Even the less than subtle swell of his belly. Putting a uniform on just because the ship said so was almost offensive. Instead, John reached in and extracted the glove that connected him to the electronics on the vessel and slipped it on.

It beeped and chimed as the ship remeasured John's personal stats, checking his finally equalizing heartrate and his respiration, adjusting the atmosphere to provide just the amount of oxygen his body needed, then flashed green to alert him that he was in fact healthy and ready for work. He sighed with a little more relief than he expected and rubbed the tesitcles pulsing against their supportive, white harness. It was a neurotic tick he'd developed years ago but it did make him feel better.

He shivered at the sensation of stroking himself after a year without it. Admittedly, to John's conscious mind it had only been moments and his body had only aged a few days but his balls seemed to know they'd been ignored for much longer than they ever had been before. They were massive and swollen, even for his exaggerated size. He felt like he had pumpkins stuffed in his underwear. He would have sworn he could feel them mixing up more of his semen churning and pulsing against his legs while he prepared his mind for work. It was a distressing feeling even though it was remarkably pleasant. Distracting may have been the more accurate word. Still he couldn't stop to handle it. He had work to do and the ship had been so polite about it.

He pushed away from the locker, his balls swinging their inertia against his legs despite the firm hold his trunks tried to give them. He ricocheted around corners and bounced up ladders until he found himself at the door to the engineering deck. A touch of his glove, and the door unsealed and swooshed open, warmer air greeting him and seeming to focus the wave on his crotch, making the bear shiver and moan under his breath. His cock swelled against the cloth too, releasing some of the pressure off his balls and giving him the distinct feeling of them filling even further as his body remembered very fondly what it felt like to be aroused.

Lights flashed and blinked, giving John something to draw his attention away from his increasing masculinity. He bounced from wall to wall, his hardening cock slapping most of the padding along the way until he finally floated to a stop at his station. He pressed his hand against the panel, downloading his data but his cock blocked his view, throbbing insistently as he tried to start his work. The more he tried to ignore it, pressing it away with one hand while he read his instructions with the other, the more wild it acted.

Precum drooled through the soft fabric, his copious flow quickly revealing ruddy skin through the increasingly transparent shroud. The air in the ships was very neutral, scrubbed constantly to keep particles from damaging the sensitive systems or the crewman's still vulnerable lungs so when his musk drifted away from his body the full effect of it hit John's nostrils like a truck. His head swam for a moment, his body pulling his lungs more open than they had been in a year to enjoy the distinctly male and the distinctly sexual perfume to its fullest extent.

For a moment, the bear's lust fed the bear's lust. A feedback loop of breath after breath until his cock rose up the three feet to his nose and slapped it hard with a particular eager beat of his heart. He wasn't going to be able to ignore this. He couldn't even hold it back anymore as the gaping waistband, stretched out much further than its designer intended by his titanic erection, let his precum drift into the air. It floated in chaotic bolas, turning and whirling like tiny liquid galaxies through the air around him.

Globes and ropes and slings of it poured out of his underwear like those toys filled with water and blue oil from the 20th century. John watched them for a moment, thinking the light glittering off them made it a rather pretty display. Some of them rolled off his face, doing a weird combination of splatting and bouncing, leaving him feeling only a portion as wet as he would have otherwise. The mesmerizing swirls of his own sexuality had pushed the technology and machinery around him out of his mind and only when a bright flash of yellow illuminated his own little gooey sector of the universe reminded him that his glove still had lots of chores for him to do, did he try to pull his underwear back down his length so he could read the new message tucking it to the side, curling, or more accurately, bending, around his thick form.

I have detected a distinctive peak of sexual arousal, Mr Grey, the ship remarked sympathetically. Your contract stated that you would be given a special modification which would make you more suitable to the maintenance of this vessel and this modification appears to now be active.

John could remember no such thing. Some lab techs took an extra long time with him because of his condition, an extra inoculation or two, but he couldn't think of any reason why his boner would have anything to do with the ship. Of course, the thought of people fondling and stroking his length, measuring and gripping and testing it only made his underwear tent again when his head escaped its prison wrapped around his hip. He needed to get off. The ship talking about his erection was only making it worse. So he unceremoniously pulled the waistband all the way over his dick head and let the poor underwear snap wetly into place against his balls. The resilient elastic gave a pleasant slap to his scrotum, reprimanding him for taking so long to relieve its pressure and making making him fire off a long jet into the air to fill engineering with even more of his liquid lust.

He reached down and grasped the fat meat in front of him. The bear's meaty fingers couldn't reach all the way around it. He might have need four hands to really grasp the whole way around. But he thought it was the best way for his cock to be. It meant he didn't have a lot of partners actually taking him inside them but he didn't much care. He loved his dick and by the way it jumped at his attention he knew it loved him back.

The bear didn't get to finish more than a few strokes, feeling the subtle veins crawling up the sides of his length or the wet skin squishing precum between his fingers into a light froth before the computer interrupted with a firm red flash.

Please do not masturbate. It said sharply, a very clinical map of his his genitals appearing on the screen beside the messages. Your genitals have been modified to produce a chemical compound during suspended animation that can be harvested for use as omnilube. Please follow the green lights to a harvesting station before you complete any other task as your arousal has become too extreme.

Omnilube? He recalled the stuff. It was amazing feat of technology. Coolant, antifreeze, lubricant; it was the Swiss Army Knife of modern transportation maintenance. He'd never thought someone could make it organically though. Of course someone was hoarding the tech, Synergist if he remembered correctly. Capitalists hated making the process known to anyone who could imitate it. But if his balls were swollen with omnilube he couldn't very well just pump it into the air. And the computer was just trying to protect its systems. It need the fluid probably as much as he needed to get rid of it so he bounced and bounded again, leaving a trail of glittering sex stars behind him as he navigated around engineering's various stations and supports.

This was definitely a room built with gravity in mind. There were a lot of things just in the way, still everything was soft and round so his cock and his still swelling balls simply sprayed more and more as he followed his lights and finally found himself beneath the drive core looking at a quartet of curiously reclined chairs. Under the dim blue of the glowing core the seat assigned to him shined a dull green shutting the light off once he touched it and swung his meaty lower half into place. The light on his wrist flashed again, showing him how to strap himself in so the machine could once again take his vitals. After a few snaps of his harness he was settled in place, and his balls floated in place, throbbing eagerly to be harvested.

He pressed his gloved hand to the panel beneath it, watching as the two chatted back and forth about his exaggerated manhood. Finally they blinked simultaneously and a message came for him through his glove.

You appear to have an excess of omnilube in your system and it must all be extracted immediately. Near the end of the process it may become uncomfortable however this system is designed to be pleasureable and will do its best to adjust to your changing sensitivity. Please relax and do not flex any pelvic muscles until the extraction device is sealed firmly to your penis.

Preprogrammed dirty talk. Maybe it was weird that it was doing it for him but he didn't want to question it. Instead, John sighed happily and let the ship lower a conduit from the core. Luckily it wasn't connected to the flickering bolts of energy dancing around above him like he was getting a show to go along with the soft, subtly textured hose struggling to wrap itself around his dick.

The slightly cool seal, was tight around his flesh, backing up the precum that was, until a moment ago, sputtering out of him and into the air around him, making a field of blue orbs flicker in time with the ship's own private dance. Now he could feel a subtle vacuum dragging the precum right out of his dick, tugging him deeper into the ship and stroking him slowly down like adding more pressure would let it empty him out that much faster. But soon enough each of his 36 inches was snuggly encased in cool, sucking spaceship and he flexed to make sure it was deeply in place.

A deep groan rumbled out of the bear when the vibrating vacuum increased in power, suck even deeper into his body for the precious omnilube inside him. He could feel his altered semen rising up in him as his sensitive meat sparked with pleasure from the texture pulsing up and down in a gentle milking motion. John couldn't get over the strangeness of the whole thing but he was getting the very first blowjob of his life and the harvester was really good at it. Its biometrics knew exactly where to squeeze and tug while he relaxed and enjoyed the sights and sounds.

The whir of the vacuum, the drone of the core, the wet sucking around his cock, a delightfully bizarre cacophony of sex that made his balls jump eagerly for joy. He was tender and pent up from a year of production and it didn't take him long to approach his first climax, cum bubbling up in him until he moaned out slow and low, almost like he was trying to hide his intense orgasm from the rest of the suspended crew as his cum burst into the conduit. He could see through the mostly clear tubing as his modified seed bloated through the length of it, stretching it out even while the machines drew it up into the systems.

He groaned and shook as his usually drawn out orgasm matched then outlasted all of his old ones. More and more semen plowing into the ship's bowels churning into the core, the blue turning a dull white for a moment then calming to more mellow purple colour as the energy was filtered through his cum to help stabilize the course of power through the ship.

He panted and sighed as the tube finally returned to it normal size and his cock relaxed, letting the distended tube shrink again. He felt good, his balls had gone back to the size of pumpkins, still excessive but much more manageable than they'd become by the time the harvesting began, and he had a good buzz of endorphins running through his body. The one good part about not cumming for a year. The bear patted the seat, thanking the ship for it's clever attentions.

Your body has responded well to modification and your omnilube has been rated "Grade S", The computer responded with a proud chime. It was nice to be told he was better than expected and the computer knew how to give a compliment without blowing it out of proportion. Extraction will resume in 20 seconds. Due to your current refractory state, level 2 techniques will be deployed. Please remain relaxed.

John closed his eyes and contemplating napping until the seat under him shifted, scooping his balls down under him into a warm, tight, vibrating pit, massaging them deeply, applying pressure to all the right spots and even tugging gently every so often. It was very thorough about the whole process, even timing a roller against his taint as the machine did its best to force his cock erect again.

Growling under his breath, the bear tried to go with the flow, but his arousal was coming slow, swelling inch by inch into the ship's tubing gradually overriding his body's desire to just laze about. He even tried clenching his muscles to guide even more of his energy into his dick but it wasn't working as well as he or the ship wanted.

Not to be disappointed, the ship flashed to his glove simply stating Level 3 techniques are being deployed. Please remain relaxed, I will attempt to compensate for any displeasure.

Suddenly, John was a bit distressed at the remark but when the harvester pulled his underwear off his ass he understood. He did his best to relax as something warm and wet pressed against his newly bared cheeks and suppressed the urge to clench as it slipped deep into his body. After the larger intruder wriggled its way in a second snaked underneath it, coiling over his massive prostate and pressing down tight on it. now with his whole groin commanded by the vessel he knew he was in for a ride. The seat fucked him gently, filling his tunnel and pulsating remarkably like a real cock, sliding in and out and each revolution pressing the coil deeper and tighter against his prostate, milking it gently and pressing the whole thing together.

He was still getting hard but his body was already releasing some of the omni lube, mixed with precum unfortunately but it had a rich colour to it that was as good a sign as any that the ship was getting what it wanted. He groaned and moaned loudly as the vacuum returned in full force, sucking up his juices as the harvester worked him over, his prostate starting to tingle as it used him more completely.

He felt his body ejaculating, His muscles were forcing his cum out. The ship was forcing him to feed it his cum. He felt gallons of Grey-brand Omnilube pouring through him and it felt good. He didn't even need to orgasm and it felt good. The machine did a good job of keeping the fucking just right and the pulsing sensation in his prostate never got too sharp while the rest of him was milked incessantly. Heated spooge flowed out of him, without end he could feel himself approaching orgasm again as he cummed into the ship like a faucet turned open.

He had a great job, he thought to himself just before his second orgasm hit. The flow didn't change for a moment but the ship's biometrics eventually shifted to turn his flow up to overdrive as it felt him cum then relax when he started to come down again. But it didn't stop this time. It just kept going, draining his body faster than it could produce, milking him harder and hard dragging him forcibly toward orgasm again.

Eventually he stopped trying to tell the difference between orgasm and extraction, the two becoming either end of a repeating cycle until after hours of being sexually dominated by his vessel, John was released, panting and exhausted and confused by his limp cock falling against his face.

The glove blinked once more for his attention and turned his head groggily. Thank you, Mr Grey. I apologize for any discomfort you may have experienced. because of this medical emergency you are dismissed from duty for the rest of the day. Please follow the yellow lights to the galley and enjoy the meal prepared for you. There are a number of forms of entertainment available for you as well. You will be alerted when you are ready to return to suspended animation.

John really want to just take a nap in the chair but eventually the tubes and phalluses extracted themselves and the harness blinked dimly alerting him how to exit the device. He sighed and complied once again, drifting off into the air still filled with his precum though much of it had migrated toward the scrubbers to keep the ship safe from his moisture. He was hungry and if they were going to give him his one day of work a year off and let someone else take care of it he might as well see what there was to do. Still he could feel his nethers vibrate, pulsating with the aftershocks of the harvesting and he couldn't help but long for next year when he would be thawed out again.
