It happened amidst the constant bickering while Krillin was waiting around for Bulma to make a wish, the dragon balls more a formality than an adventure these days. There was always a pang of nostalgia when they had their yearly collection, though things had gotten more annoying since Goku had other priorities and spending a few days with Vegeta and Bulma always made him feel like a third training wheel to their constant mix of bickering and half restrained foreplay. He just missed the old days, when they really felt like best buds and spent all day training together. Or even the days when they both had downtime. With an elongated sigh he spoke without thinking, reflecting as the bickering power couple argued over what to wish for, Krillin not thinking of the equally impatient Shenron already summoned.
“I wish Goku could be by my side every day.”
“Hmm… GRANTED!”
Before anyone could even process what happened, Shenron was gone, the balls all splitting apart as Krillin wondered what Bulma had settled on, already forgetting his half muttered wish by the time he heard Bulma scream out, “Get Dende on the phone! Tell that gutless god that his products are DEFECTIVE!”
There were limits to what the power of the dragon balls could do, a being like Goku far too powerful at this point to destroy or take down in a conventional way, but the wording of the wish left a certain amount of wiggle room, the magic flinging halfway across the world to strike the unsuspecting protector in the middle of flying back home. It was like a blaring headache as the world brightened, Goku feeling dizzy as his flight turned more into a sudden crash landing, his body crashing into a thankfully deserted rocky outcrop.
“Huh? What was that? Hello? Red ribbon guys, are there some of you still hiding somewhere?”
No response, just an insistent throbbing in his temples that felt like a spot was humming, an advanced copy of a personalized nanomachine incubator purring to life as metallic tendrils weaved their way down his spinal column, more of that strange internal humming causing awkward muscle spasms as he smacked around his body like a swarm of mosquitoes were harassing him.
“Hello 18. Irregularities were detected in our last saved backup. Improvements in aerodynamics and strength have been detected. Shall we proceed?”
It was a calm androgynous voice, sort of like the ones Bulma had answer her calls, Goku again trying to find anyone, sensing only his own chi as he realized the voice wasn’t just nearby, but seemingly inside his head.
“Oh is this like telepathy? I wanted to learn that but I had to get back and Bulma already had those ear thingies? Who is this and what are you doing? Cause this feels weird…”
The buzz was continuing to spread, like a second heartbeat thrumming through his muscles, circulating into arteries as it wrapped around his internals in a complementary flow of liquimetal support.
“I am an advanced Homeostasis AI Unit for designated user 18. I exist to only appear during the most extreme eventualities. Shall I commence the update?”
By the time it threaded down to his toes, the whole buzzing thing felt kind of nice, and Goku couldn’t sense any malice in its voice. Besides it said it could make him stronger? Maybe it was an advanced civilization reaching out to teach him more techniques, though he wasn’t going to hop on it just yet.
“What does this update thingy involve? Could you walk me through it?”
There was a slight pause, Goku flinching a bit at the whirring between his ears as the voice processed his question.
“It seems you need a reminder. In cases of outside tampering or genetic deterioration, this system is made to ensure as pleasant an upgrade as physically possible. While I am not allowed to begin the upgrade without consent, I am allowed to recreate the physical sensations.”
There was no warning, Goku toppling over as his voice moaned loud enough to cause cracks in the ground around him, his own thrashing sending up a cloud of dust as he gasped and shuddered. It was like when Chi-Chi wanted to have “adult fun” or another kid but way stronger, his whole body alight with sparks of raw bliss, pleasure so potent it was almost scary how easily his mind just wanted to shut down and let it wash over him. Then it faded, Goku gurgling as that incredible passion died down, his neurons directed to ease him out as his cock wilted, an unsatisfying end to what had been one of the best feelings in his life.
“Shall I commence the update?”
“Y-Yes!”
He immediately clutched his lips but the damage had been done, more whirring as thin wires of heat bubbled throughout his body. A fine sheen of sweat followed, his body quaking as a sudden pressure filled his hips, the saiyan’s brow creasing as he clutched at an intense discomfort that was just shy of being painful. Something was inside of him, scraping against his pelvis as he wriggled, the pressure only worsening with time.
“Wh-What the hehhck is this? What are you doing to m-HEEEEE~?”
A box had been forming, countless microscopic threads digging into his inner pelvic area, a small rounded piston sliding up the base of his cock before buzzing. Goku wasn’t much of a carnal enjoyer, romance and love kind of afterthoughts even if the kid making sessions he had with Chi-Chi felt pretty good. This was something else entirely, a mechanical vibrator shoved between prostate and cock, buzzing at a high enough frequency to make his insides feel half numb, half blisteringly orgasmic as more subtle jabs poked into his genitalia and prepared his body for the changes to come.
“Please calm down, this is just the start of the update. Adjusting hormone production for max efficiency.”
He didn’t understand what it was talking about, and even if he could, his internals were being massaged in the most incredible way, his lids fluttering as he rubbed against the earthen dust. His endocrine system was being hijacked, a thick sheen of fluids too thick to be sweat saturating his gi as oils were ejected from his rougher skin, his body buzzing like a cicada as all over hairs were being plucked, his skin smoothing over as it tightened, the slightly rugged tan paling itself to a softer peach tone. The hair removal caused a prickly feeling across what remained of his hair, one hand rubbing at the buzzing base of his cock, the other around his brow and scalp, his eyebrows shaping into stylized lines, a golden color spilling up the follicles while his pubic hair shaved itself into a golden triangle.
As the blonde creeped up his spiked tufts of black, the overall shape deformed, the greasy tangles that stuck together in his usual shape gradually cleansed of impurities causing each section to sag like a deflating balloon. It wasn’t till the whole thing collapsed that he noticed a floral scent tickling his nose, silky strands of spun gold fringing his chin as a blonde cowlick bobbed into his vision.
“D-Hiiiid I go S-huuuper Saiyan? But I didnGHH AHHH AHHH~!”
The piston retracted, then thrust again, a damp patch spreading over his orange gi’s pants and dying it blue as his muscles flexed, the buzzing making his dense crop of musculature shift about like a bed of sand as down to his genetic code edits were being made. It looked like everything was shivering, small tears in the bulging structures of his physique spreading as the jostled muscle groups were contracting, the tightness of his skin squashing down on plates of muscle, bubbling pops bursting in a ticklish array of diminishing bulk. All these subtler motions were drowned out by the ceaseless internal fondling of his most tender spots. Even something as big as the meaty stump of his cut off monkey tail was thrusting inside, tangled up in the internal penetration, his Saiyan heritage being filtered and edited to purely human as the submerged stump was pulped and ejected out of a cock that was beginning to feel wrong.
It wasn’t like he ever really thought about it much beyond when Chi-Chi wanted to use it, but had it ever been this stiff or this tender? Even with the AI inside explaining steps, it wasn’t like Goku would know what a hormone was and his groin was being saturated with estrogen, the chemical bath making the inner urethra grow textured, his dome shaped tip ever so slightly pressing down as the spongier material wrung out a thick stew of nano infused release.
“Hormone saturation levels adjusted. Primary conditioning and facial interface remodeling commencing.”
More words he didn’t understand, not that it mattered, the pleasure radiating outwards as the piston made his whole body quake, muscle pulling in as waste material leaked from his cock, more patches of blue appearing on his clothing as it all tightened down a few sizes, his skull rattling his brain about as wiring dove in to reformat his throbbing, pleasure addled temples.
“OHHHH~ OH OHHHH~!”
It was weird, his thoughts of Chi-Chi when they made babies twisting, his own bucking far less satisfying than the feeling of the piston thrusting up and down, his memories replaying the way Chi-Chi seemed to enjoy it, her moans echoing, her begs to do ‘it’ harder, whatever it was getting clearer as his flexed temples deflated with a wet crunch. He needed to touch himself, his body aching contact, needy like he had never felt as meaty palms writhed, muscle compacting them in alongside his shrinking face, bones thoroughly screwed into by the nano network giving in to the genetic orders, slim hands fondling his softening muscle, lips tingling as fat was slowly added to plumpen their shape from the converted shaved bone of his slimming cheeks.
“Beginning secondary task of mass displacement. Placing waste adapter for more efficient management.”
Something hard thrust up his cock, Goku gurgling as fine wires flowered out the tip, cobweb thin strands clasping around the mushroom head and buzzing. That palpable gap between his pelvis suddenly widened, hips popping as the widening vacuum sucked at his core, his voice cracking alongside a few ribs as his broad frame contracted. A rush of melted down waste drained into the gap, ramming his prostate as more and more images of Chi-Chi’s pleasure replayed, a white fountain of fluid spraying out as his cock was suddenly angled to the left then right, the orgasmic spray halted as his arms were covered in the white, slippery fluids firmly wrapping along his arms, tearing through the mutating gi as the start of sleeves while Goku’s innards churned. He couldn’t think, cock aching as it could only throb, his mind lingering on *how much better it felt to be penetrated* as the roiling slurry of fluids rumbling behind his cock continued to shift.
“Primary conditioning achieved. Secondary conditioning in tandem with mass displacement shall begin. Please enjoy.”
Two sharp pricks stabbed behind his nipples, something hot pumping in as he screamed, one hand tearing at the thin orange fabric, ripping it down the middle as his gi pulled in the torn layers into a blue jean jacket, wires drilling through pecs, all twisted under a pumping mechanism whose handles both spread his nipples thick and pink. Suddenly the mechanisms squeezed, his pecs looking like some unseen force was gripping the muscular plates and scrunching them, sinewy pops ringing out as his tender nipples depressed before plunging back up, pressure doming each pec as the neural rewiring went haywire.
Each mechanical scrunch was a drawn out process, flashes of when he’d squeeze or suck his- some broad’s chest percolating, flushes of jealousy being conditioned in, his eyes watering as they slowly widened from mirror neurons all flaring in tandem with the sucking pulls of his chest. The pressure was delirious, three points of blissful resolve as each slow unpuckering of his nipples inflated the spreading domestic, his cock finally allowed more releases as sticky black spray on pantyhose sprayed up as his tip sank further, widening as the black splotches splattered onto his chest in the barest outline of a shirt, fibers tactically massaging his malleable muscle as the roiling flesh continued to congregate under pumping nipples.
“AHH AHHHN WHAT AHHHRE Y-OOOOH OOOH FUUUUUUCK~!”
Sleeves squeezed his arms and shoulders inwards, the muscle squeezed out like tubes of toothpaste directly into his tits as his ribs continued to contract, inches splattering out or forwards as his growing tits continued to thoroughly flatten themselves in a pumping motion like a rough lover was battering them, memories of times he had messed up that balance flaring as his brow continued to flatten, his throat grunting and moaning in a tone that half felt right and half like someone familiar as his cock continued to unleash black splashes of fabric.
In a matter of minutes his entire core had collapsed, his spine bent by the multiple pistoning vacuums, his hips and chest both accented as his barrel chested body was sucked into an hourglass, the violent jostling of his breasts turning to a more practiced, tender pleasuring. His own slender hands added to the feeling of rightness as they played with his swollen breasts, tracing the inwards slope of his toned, curvy waist, the pleasure peaking with a final feminizing suck as he moaned out, “KRIIIIILLIIIIIIIN~!”
That was finally a step too far, the mental conditioning facing the first bit of resistance as Goku internally recoiled, confused why he’d ever think of his short, longtime lover~. The meshes squeezed, Goku squealing as he suddenly came, more memories of Krillin over the years flashing at every forced release as he groaned, feeling splashes of pantyhose squirt down his legs. He was now aware of a pulsing suck somewhere in his head, thoughts slipping away, memories shifting, his irises glowing as arcs of reconditioning blazed through his brain matter.
“S-STAHHHHP Thhaaaht you fuhhhcking fr-HEEEAKS THat’s my h-UHHHSB- GAHH?!”
“Conversion cannot be stopped midway. What is the problem? Does it have to do with the pipsqueak?”
“DON’T CALL KRILL-IHHHHNGH~?!”
Goku was never much of a thinker, and the advanced system knew exactly how to goad him into repeating the name triggering the next set of reformatting, transplanting his feelings for Chi-Chi, fighting and the pleasure down below to every utterance of Krillin’s name as the rewiring sparks were making his teared up irises glow an electric blue. Just like the snatches of curses flowing freely out the once pure man’s mouth, feminine desires were slipping into his mind, the lack of sexual desire making it easy to have his breasts overshadow his cock, the piston still thrusting into it as further wires threaded into his prostate. All his screaming managed to do was make the system’s job easier as drool spilled down full lips, his nose grinding inwards as tiny poking threads lengthened his eyelashes, that thrusting from below joined above as his eyes fully slanted with a loud crunch.
Memories flooded in alongside intelligence, Gok8 realizing he was being distracted, struggling to ignore all the forces pleasuring him as his malformed pantyhose squeezed against his still stocky legs, his uniform’s pants unfurling and ripping in two as they wrapped around his feet as an overly tight pair of brown boots. He had to find help, needed anyone to know what was happening to him so they could undo this with a wish. He had to fly home now.
“Understood. Rerouting. Rerouting. Rerou-“
“SHUT UHHHHP YOU MMGH FUUUHCKING NUISANCE!”
It was hard to focus with it yammering all the time in her head, plus it sounded a lot like Gero that perverted mad scientist asshole which was the last thing she wanted to hear as he flew off in an awkward, trailing line. It wasn’t like flying took the most focus in the world, but his tits kept jostling in the wind, his own moans turning him on as he couldn’t help the flashes of Krillin appearing as his toes sank into his feet, the shoes shaping and curving his bottoms as more converted releases splattered down his thighs. Keeping anything straight was fucking impossible, his flight lines curving like his calves as he flew from desolate wasteland to a thriving metropolis, rushing to a familiar door as he hoped someone was home to-
“Arrived.”
“Huh? But i-isNNGH this Kr-HIIILLNNGH’S GAHHH OHH FUUUUCK~!”
Everywhere he looked were triggers, pistons hastening their pumps as the memories assaulted him, Go8 falling to his knees as the contact made them snap inwards, the hollow gap behind his cock spreading as every inch of him felt well and truly fucked.
“OHH OHHH P-PL-HEEEEASE MY HEAD MY AHHHHN YESSS~!”
Friendship was becoming lustful, his eyes fluttering as Krillin’s scent was all around, memories of a life that felt increasingly more real than his own pouring in as his legs spasmed. Muscle was bloating out, heels digging upwards as his calves bulged nicely, a few more pumps sending his thighs to wrap around his already aching cock as years of squats and body building were being modified into the ultimate cock crushing thighs. Everything felt so good he didn’t even know what to focus on to try and hold on, begging for help, begging f-for… Krillin~
A while back Go8 remembered Krillin mentioning 18 had “the right parts” or something, and now it was time to get them himself, the threaded wires digging into his prostate, Go8’s mind flooding with memory after memory as his g spot was being spread apart. Out spewed every last drop of sperm he’d ever produce, one hand constantly at her temples as they throbbed, the other between her thighs as the drilling intensified, the organ throbbing desperately as it warped into a womb, two tubes digging outwards before G8 felt twin stabs inside her balls. The piston went back to buzzing, making the whole area like a bed of sand as two viney ropes tugged, her balls slowly filling her as all she could imagine was Krillin on top of her, rubbing his bald head as she yelled for him to cut the crap and finish the foreplay and just stick it-
PLOP PLOP
“YES YESSSS OH GOD I NEED THIS!”
She didn’t know what was getting into her, her mind struggling to form a coherent thought, G18 stumbling into the bedroom, everything hot as her skin was flaring, her balless cock feeling harder by the second as her innards were as muddled as her memories. The only thoughts allowed were of Krillin, so many days spent training and hanging around taking romantic connotations, the mesh clamped around his tip from earlier applying pressure as with every needy thought, her cock sank.
No release was allowed, just pure lust as a chemical bath washed away earth’s strongest hero into earth’s strongest wife, the piston slotting in and linking to the mesh as her tip continued to distend. All she could do was howl as she threw herself onto their bed, letting years of sexual desire flow as she grinded through the skirt and pantyhose, feeling his cock as if it was actually there as she groaned in delight. All that was left was the final process, shaft grafted and molded to her deepening walls, tip sinking as the mushroom head partially separated around the widening slit, one final squeeze of the mesh popping it into a clit as one last click of the piston pulled it all the way in, the newly christened 18 finally able to cum.
But that was hardly enough for her, 18 feeling uncharacteristically needy at the moment, waiting for her hubby to come home, needing to rock his world, wondering why it felt like she’d been apart from him for ages. Well it wasn’t like they had a quiet honeymoon period but she’d be sure to really make her feelings known the second he walked in, 18 excited to grant his every wish in the bedroom, a chaotic, wild night ahead for both of them. Till the original came back.
But that’s a story for next time on Dragon Ball TG!!!
