It had been an uneventful day for Dr. O’Hara and his cyborg pig son, with the older hare busy in his lab for a majority of the day. Doz, the pig, had been sprawled out in front of the TV all day. At least it was mostly documentaries and stuff to actually teach the porcine cool little science and nature facts.

“Remember Doz, while I’m out with investors tonight, you’re not allowed in the lab. I’ve got some sensitive equipment in there AND half finished birthday presents. If you interrupt anything, I WILL be punishing you. This is important, got it, Piggo?”

“You can count on me Doc, I won’t be going into your lab tonight! There’s a horror movie marathon going on until three in the morning. The whole series of The Cheese Monster That Ate All The Jocks In Town is gonna be playing.”

    “I… Honestly, yeah, that’s probably a movie that exists…”

    “A movie? No, it’s EIGHT movies, and a Christmas Special.”

    “Oh uh. Okay, I’m leaving now, enjoy your shlock, Doz. Remember, no lab tonight.”

    “No lab tonight!”

The little pig lad waved from the window as his adoptive father as the hare backed his car out of the garage, out of the driveway, and down the street. A moment later and Doz was plopped across the couch, butt naked, with a bowl of puffed corn product covered in orange cheese powder, usually known as “Cheese Doodles”

    “Greetings Boys and Ghouls! I’m Spooky Dan and I’m here to provide low quality, heavily outdated humor that annoys everyone but the near braindead or stoners! I hope you fellas and fellinas are ready for some Cheddar! ‘Cause we got The Cheese Monster That Ate All The Jocks In Town. I ain’t gonna spoil anything for you folks, but…. The Cheese Monster eats all the Jocks in town. Shocker, I know. Take your potty breaks and get your snack bowls ‘cause we got ALL EIGHT MOVIES…. AND THE CHRISTMAS SPECIAL!”

    About four hours into the marathon, Doz sat up and checked the digital clock up on the wall, above the phone. 12:01. With that, the pig teen gave a grin similar to that of Jim Carrey’s Grinch, and hopped to his feet. The little tippy tappy noises of his hooves on the tile floor sounded down the halls as he headed right for the lab.

    The place was pretty swanky, but it had the vibe of a hospital, with the too clean smell and the polished white surfaces and everything. Part of the lab had been partitioned off with a few lengths of tape and a lab table. On the other side of the closed off portion was one of O’Hara’s main projects, a synthetic feral donkey. He looked super cool, with the white and blue plating over the black bendy bits. It kinda reminded the pig of the Chinese Stealth Armor from Fallout… just with white and blue pads instead of all black and stealthy. A few days back, he’d actually gotten to pet the donkey, who O’Hara had been calling Uno, and the flexible black parts honestly felt similar to the smooth underarmor shirts and undies made for athletes.

    Doz knew that Uno wasn’t his present, obviously. The donkey was for some kind of synth zoo starting up in San Diego or something. So, after a few glances over the silent, still equine, the pig moved on to the other tables and gizmos.

    There was something on a tray that looked pretty familiar. It was a little plug in jack that matched what the pig had installed in his own body. So, after reading the little inscription “Temple R” Doz hoisted it up and clicked it into the port in his right temple. 

    Almost immediately, Doz’s eyes went wide as his dick boinged up to full erection in seconds. Already, the head was oozing precum, ever so slightly pooling up in his foreskin like a tiny bowl. Sure, the pig jerked off regularly, but it had never really gotten this hard! One of his hands slipped down to squeeze and rub along the pulsing length, coaxing another blub of precum to ooze free and smear along his fingers.

    Frantically, he looked about the lab, trying to find a rag or something he could rub out a load into. As if it were placed especially for him to see, there was a smaller table up against the divided part of the lab. On that table was an assortment of different attachment parts for Uno’s genitals. A big donkey dong, fully extended and somewhat floppy, a hefty pair of nuts, a plump donut tailhole, even a plump, eager pair of equine folds, just begging for a stallion or jack to pump a load into. Beside all of those enticingly displayed android attachables, was another pussy, though it just looked smaller, there’s no way it could fit on Uno without looking ridiculous.

    This must have been the birthday present O’Hara had mentioned! Sure, it kinda looked similar to the donkey pussy, with the thick, pudgy lips and kinda loop shape to it. The big difference was an exposed clit, honestly. Other than that, it was pretty close to equine anatomy! It even was textured on the outside similarly to how the soft parts of Uno’s body were. 

    Once Doz had it picked up and spread between his fingers, he could see the glimmering, slick walls along the inside, with little ribbed rings for added sensations. After he’d started exploring the thing, it actually seemed to get wet and slippery too, with little realistic pulses running through the synthetic organ. The lips gave a wink like a real equine, and caused the pig to jump in surprise, nearly dropping the toy three or four times with his slippery hands in a rapid catch and drop fashion.

    Finally, Doz had it in his hands, and it was adequately lubricated. Of course, it had lubricated itself, because he had it in his hands, but that’s semantics, and in the porcine’s mind, he had done all the work and was obviously a natural ladies’ man. He lowered it down, hovering the needy toy over his twitching prick. A deep breath escaped from the hog as he slowly but surely eased himself into the portable cunt.

    Once he’d fully buried his cock into the tunnel, Doz began to get just a touch more confident. His hips began to wiggle and rock, and his hand moved the toy back and forth, causing a lewd little squelching noise every time he squished it up into his lap fully. Cute grunts escaped the porcine every time he pulled it away too, so an adorably lewd symphony was being made as he rutted back and forth into his early birthday present happily.

    Every few seconds, the toy flexed around his cock, causing him to lightly arch his back to keep from simply blowing his load then and there. Already, the boy’s balls and inner thighs were soaked with a mixture of synthetic feminine arousal and his own, slightly less synthetic, slightly more masculine arousal. At about the second minute mark, Doz had already started to lose control, with wild hip jerks, and drool running down his chin, and little curly flexes in his tail.

    With a final groan of pleasure, the lad squeezed the tunnel with both hands, squishing the muscular entrance even more tightly. A heavy pulse ran through his prick and the first goopy jet of his payload blasted deep into the quivering, clenching tunnel. It immediately responded by bathing the pig’s lap in a warm feminine climax with three or four spasms and squirts of clear fluids. Doz’s orgasm lasted a good fourteen shots! By the time the boy was done, his knees were shaking and he was panting out heavily.

    When he was all finished up, a gasp escaped the pig as he pulled the toy free with a messy *Splorch* noise. *Poink* The little jack device in his temple ejected itself onto the table abruptly and that horny fuzziness in the pig’s mind almost immediately faded.

    “Oh Heck! I gotta clean this up before Doc gets back and I get in trouble!”

    Doz did an admirable job of cleaning up the massive mess that he’d made. He’d wiped up all the drippings, stuck the head implant back where he’d found it, and even sprayed some air fresheners to get the smell of sloppy, sweaty pig sex out of the lab. To him, it was perfectly clean. It looked exactly like when he’d arrived. So, he went and kerflopped down onto the couch to watch the next few hours of cheesy cheese based horror movies while he dozed and waited for the hare to return home.

    It was in the wee hours of the morning when Dr. O’Hara finally returned home to find his son passed out on the couch, snoring loudly, with cheese powder on his muzzle and fingers. Of course, O’Hara already knew that Doz had been in the lab. There were cameras everywhere, and little sensors in the equipment. Heck, there were sensors in the cybernetic parts of the pig himself that told the scientist when he went in the lab and what he’d done!

    Even without all those sensors and alarms and such, it was fairly clear that the pig had been up to some naughty fun. Doz’s prick was half hard, and covered in slick gloop from his escapades with the toy. With his dick flopped against his belly as he slept, Doz had forgotten to clean himself up after putting in all that work with cleaning up his mess in the lab.

    He also didn’t seem to get the pussy cleaned out, since it had resumed oozing a portion of the porcine load onto the little pan it was sitting on.    O’Hara gave a sigh. He’d had this all planned out, and it was gonna be a lot of work to get done, especially so early in the morning with no sleep.

    Doz slowly awoke the next day to warm breath snuffling across his hair and face, and a slippery black tongue slurping the cheese powder from his snout curiously. When the pig opened his eyes, he was rather startled to find himself in something like an old horse stable, in one of the stalls, strapped to a sawhorse thing with some rectangular hay bales underneath it to add some support and some width to it. Sharing the room with him was Uno, the synthetic donkey.

    When he went to push the donkey’s face away from his, he realized another big development. Someone, most likely Dr. O’Hara, had detached his cybernetic limbs, and the poor porcine was left as a torso and head! Usually this was only for parties, impressing bigwigs or testing some new sexual based technology for the lab.

    That’s when it dawned on Doz that this was a big tech test, and he was the test dummy. The boy was about to start questioning things and try and get a feel for what was going on, when the little light plugged into his temple decided to light up and that incredibly horny burn started running through his body again, same as the night before in the lab.

    Unlike the other night in the lab, something felt different. He felt a burning need in his lower belly, and he could feel the throbbing twitches as he ached for release. The difference was that he couldn’t feel his cock jumping, instead, he felt the puffy, almost feral lips give a tense, then a wink, exposing the inner walls of his slippery, synthetic cunt. 

    His cheeks turned an almost maroon color in an intense blush as he tilted his head, only to see a mirror and camera on the wall and ceiling, showing the pig his own needy cunt’s pudgy, fat lips and swollen clit. O’Hara had swapped out his boyhood with the very pussy he’d fucked, he could swear he could even feel some of his own load still in there as feminine arousal gushed out in a firm splash at the sight of himself on such thorough display.

    Now that the horny had overtaken Doz, he started noticing things that didn’t really seem all that important at first. For one thing, Uno had his attachments added too. So a massive pair of black coated balls, and a droopy black equine cock were just casually hanging out between his hind legs and under his belly, lightly swinging as he moved. The air was heavy with pheromones too, as if O’Hara wanted to be extra sure that everyone involved was as horny as could be, even though Uno probably wasn’t affected by it in the slightest, and Doz’s only responsibility was being there.

    Of course, now that the pig was in full on horny mode, Uno had taken an intense interest. The feral donkey android just trudged around the hay bales and over between where the boy’s legs should have been, if they hadn’t been detached and stuck on a shelf for later. Doz wiggled in place in a mix of anxiety and more than a little excitement. Sure, he’d hiked his little curly tail for some guys before, but never something THIS hung, and certainly not a feral.

    It’s not like the pig was complaining all that much, he was just nervous and so desperately horny. The donkey pushed his muzzle right up against the presented snatch, those dexterous lips flipping up over the pig’s clit and just covering the whole sex like an old lady eating a peach. The lips clamped down over the whole thing, almost forming a suction cup feeling for the poor pig.

    If the sucking donkey maw on his “virgin” sex weren’t enough, the wide, flat, slobbery black tongue slurped out over his butt, tailhole, taint, and finally over his tender folds, pushing a long, drawn out moan free from the piggy’s maw.

    It was honestly worrying the pig a bit with the amount of force that Uno put behind his licks. He was getting dangerously close to simply sinking his massive tongue right up the boy’s ass and into his guts each time the donkey licked on him. The tongue slurped dramatically up into Doz’s tunnel, spreading him open wide and causing the pig to squeal out in alarmed pleasure. Thankfully, this left his butthole alone, since it was ever so slightly gaped and slick, one more lick and Uno would have gotten in there good. 

    “Oh God!”

    Doz was in heaven as the tongue spread his tunnel, grinding greedily against the pig’s cervix as he slurped up every splash of juices that squirted freely into his maw. He’d be grabbing on the donkey’s ears and head or gripping handfuls of hay at this point, if he could do anything more than arch his back against the restraints. There was a pressure inside him, rising higher and higher, similar to when he was about to cum, but different. He could only assume that it was exactly that, a climax, but feminine and all.

    “Aieeee!” cried the pig, as his inner muscles spasmed and clamped down around the invading tongue tightly. The walls of his cunt squeezed and pulsed and twitched rhythmically. Two or three spritzes of cum fired from his urethra, messily into Uno’s muzzle as he drew backwards, pulling his tongue free from the gaped hole as two or three more waves of orgasmic bliss wet the scattered hay and dirt floor below his bondage setup.

    By the time that Doz had somewhat returned to his senses, he could feel Uno pressing down over him. Those powerful front legs were pressed down on either side of him, right about where his arms should have been. The warmth radiating off of the donkey’s chest was surprisingly soothing. Almost like he wasn’t a synthetic creature, though that was intended, when O’Hara put the exhaust vents for the cooling system there, under the edges of the chest plating.

    A warm humming noise could be heard over the heavy huffing and puffing coming from the donkey’s flared nostrils. The pig couldn’t see what was causing it, though. The mirror didn’t help either, all he could see from his angle was a slightly hiked tail, a donkey donut, and the twitching epididymis along the backs of Uno’s heavy black nuts. 

    The real magic was happening under Uno’s belly, against Doz’s butt. A trio of red lasers trailed about, oriented, adjusted themselves meticulously, then locked on target. The target was the gaped, drooling pig pussy. If the purpose of the lasers wasn’t obvious already, the donkey leaned his hips back, flexed his member, and prodded the blunt tip right up against the porcine sex on the first press. Laser guided dong assistance, what a time to be alive. 

    Now that the donkey had himself in position, he just jerked his hips forward and spread the poor boy open, straight to his cybernetic cervix in one push. A loud squeal and gasp escaped the pig as he wriggled in place. Rather than wait for his new cock sleeve to get used to the intrusion, Uno instead began to rut hard into the boy, hips dragging back about five inches, before ramming the squishy, sloppy length back up against the barrier, over and over. Unlike a real donkey, instead of five or six good thrusts and a grunt, Uno seems to have the endurance and stamina to last as long as is needed. Though honestly, O’Hara might be somewhere out of sight with a big red “NUT” button.

    The sounds of Uno snorting, and the sloppy sex sounds were really getting to poor Doz. His cunt was aching with overexertion and need for more, and the donkey seemed perfectly happy to give it to him. Each thrust seemed to get a bit more desperate and needy, with little grunts escaping the equine. His powerfully muscled synthetic flanks tensing and twitching as he slammed away at the pig below him, bulging out Doz’s tummy with the size of the penetration.

    The piggy could feel warmth seeping and squirting into him, and at first, he thought that maybe Uno was finishing and that it was over and he could get a breather, but no, it was just the goopy, almost pudding like precum splattering freely from the squishy equine tool. A loud squeak escaped the boy as he clamped down like a vice around Uno’s throbbing prick. Undulating waves of muscle spasms tried desperately to milk the donkey’s dick, and still he didn’t unload in him.

    It took a whole thirty five more minutes to Uno to finally be allowed to cum. By this point, Doz was a complete, shivering, crying mess of overstimulation and exhaustion. Uno on the other hand, had never done this before and the waves of pleasure that washed over his bioplastic and circuitry driven brain sent the donkey into a loud braying fit, mouth wide, lips flipped up, honking to the heavens as his cockhead flared out to the size of a frickin’ tea saucer inside of the pig. The little bump around his urethra pressed right up against the opening in the cervix, and with a powerful throb, the first rope of gloopy, off-white donkey batter squirted up into the boy’s womb. This was quickly followed by another rope, and another. It continued on and on, lightly swelling the kid’s belly to look a few weeks pregnant, before it was pushed back onto the donkey’s tensing, twitching balls, and the hay bales and floor below in a splatterfest mess.

Both Uno and Doz sat there, wide eyed and panting out heavily for a good five minutes, before the donkey shimmied his front hooves back a few feet and hopped down, plopping the limp, still flared cockhead free from the gaped, well used, heavily creampied cunt. 

Doz couldn’t help it, after a few shuddering breaths, the pig passed out into a deep, exhaustion fueled slumber that not even the horny button in his head could wake him from.
