Ticklish Transformation
Keith was strapped to a table, surrounded by darkness, his wrists and ankles clamped down to the surface. As he woke up he realised he was still in his con fursuit: A stylised smiling Asriel, complete with shirt and shorts. That suit still encased his whole body, he was looking out through the eyes of his elaborate headpiece. The only thing he saw was the grey walls, rising into the dark, unlit ceiling.
“SUBJECT HAS REGAINED CONSCIOUSNESS.” An emotionless, mechanical voice echoed through the room. “BEGIN APPLICATION OF TRANSFORMATIVE GEL.”
The next moment something lowered out of the darkness above him, something that looked like a huge metal cook-pot, as tall as himself, suspended by two metal bars. As he watched, he heard a mechanical whirring sound and the thing began to tilt. He panicked as he saw the lip of the pot turning down, aiming the green sludge inside directly over him. He had just a moment to scream before it splashed onto his face.
His head immediately felt encased in the sticky, binding gunge. The fursuit head had felt as lightweight as a pair of glasses compared to this. Screaming had been a mistake, as a fraction of whatever-this-was had gotten inside his mouth before sealing it up, and he could feel it coating across his tongue and teeth.
The pouring tank hadn’t stopped, but it was moving lower, he felt the foul stuff pouring over his torso, then his legs, leaving his whole body feeling wretchedly encased. He struggled to breathe. His eyes were covered.
Suddenly he felt a crack as his jaw extruded forward. It was followed by his nose and mouth, similarly projecting forwards. A sensation of pressure in his scalp became two sturdy nubs pointing from his head. There was no pain, but a hideous sense of dissociation as his body wracked with change from head to toe. His hands and feet became smaller, wider with sensitive pads. His frame became slight and skinny, the suit and his flesh merging into one.
Keith found he could breathe again but through an unfamiliar nose, a white furred snout sitting over his muzzle. He opened his eyes and found he was no longer looking out through the eyes of the suit, but was seeing the room around him clearly. Yet, when he turned down to look at himself the view was still the same. The same white fur, the same striped shirt, the same beige shorts. But the prickling sensations told him that this was no mere suit, that fur was his.
“SUBJECT SUIT ASSIMILATION COMPLETE.” The mechanical voice interrupted his thoughts. “BEGINNING PHYSICAL TRAINING.”
“Wait!” Keith called out, twisting his head to try and see anything through the gloom. “Who are you?! What are you doi- EEP!”
He was brought up short by a strange prickling sensation against his feet. He looked down and saw something that looked like a roller, covered in small bristles, pressing against his freshly-minted paw-pads. There was a mechanical beep and the rollers started to turn.
The sudden sensation of soft bristles brushing against his feet made him giggle, he had always been a little ticklish. He tried to pull his feet away but the cuffs held him firmly in place. All he could do was grit his teeth and shut his eyes, stifling his laughter as best he could.
Then there was another beep and he felt some soft tendrils pressing against his hands. The next moment he was gasping and whining as whatever-it-was delicately, carefully caressed all around his paws, in between his fingers and across his palm-pads. He would never have imagined his hands could be so sensitive!
He burst out in laughter, yelping and gasping as his sensitive spots were massaged. “PUH-PLEASE! AHEHEHEHE! STAH-STOP! GYAHAHAHAHAAH!”
With the sound he was making the next beep was almost inaudible. To his horror a couple more mechanical arms came up to his sides, bearing rollers covered in soft nubs. The next moment they were pressed against him rolling down slowly from his armpits down his torso.
He was shrieking with laughter now. He didn’t want to be, there was nothing funny about this situation, but the stimulation against his body was too much for him to resist. Heaving his body against the restraints he writhed under the mechanical touch.
“STAH-STOOOOOP!” He screamed out in between breathless gasps.
The machine paid no notice to his outbursts, continuing the relentless assault. Keith could do nothing but writhe on the table, laughing hysterically as his whole body was mechanically manhandled.
“BIOMETRIC SCAN COMPLETE.” Came the next mechanical voice, only faintly registering in Keith’s mind over the endless stimulation. “BEGIN MENTAL TRAINING.”
The next moment the world went dark. A visor had sprung down from somewhere and snapped over his eyes. Moments later all sound was drowned out. He wasn’t sure what had happened but he felt something soft encasing his goat ears.
Without any change in the tempo of the tickling this change had made everything feel far worse. Without any sight the tensions against his body felt that much stronger. The speakers in his ears must have been playing some noise cancelling sounds too, his own laughter sounded faint and muted as if it were far away. He was feeling horribly dissociated.
The next moment something flashed across his vision. Colour filled his sight then coalesced until it focused into a picture of Asriel. Keith knew the character well, after all, hadn’t he chosen to cosplay as him? The chirpy goat boy, kind and chipper (pre-transformation of course) always felt like such a happy mindset to get into. Now images of Asriel, even some he could recognise from browsing online, were being flashed before his eyes. He caught the faint glimpse of some text around the edge of his vision, but it always disappeared when he tried to focus on it.
But now those images were being bombarded into his eyeballs, all while his sensitive skin was being bullied by the prickly rollers travelling up and down his body. Something else was happening too. He could feel his clothing being pulled away and cool air playing across the fur on his crotch.
The next moment he had his answer. A sensation like a hundred tiny toothbrushes started brushing all round his crotch, his balls and his sensitive shaft. His screaming reached a crescendo as the sensation multiplied in his hands and feet as well, more brushes, faster brushes, softer brushes, it was impossible to tell. The white-hot nerve-signals shot through his body, leaving his brain feeling as if it were being electrocuted.
He took in breath for another scream, but was suddenly cut off. Something round and soft had been jammed into his open muzzle. Without even the ability to cry out all other sensations grew stronger. He knew he was still thrashing about on the table, but even those feelings were numbed by the unceasing stimulation to his most sensitive spots.
Now, while he was his most vulnerable, the images playing across his eyes began to change. Before they had all been images of the happy goat boy playing, talking with his family or strolling in nature. Now they changed, Asriel was as chipper as ever but he was always naked below the waist, his cock and balls swinging freely.
There was a lot more nudity in all of the images. Asriel in a suggestive pose, spreading his legs in a bar full of other half-dressed characters. Asriel taking a 12-inch strap-on from a tall purple cat-woman. Asriel stroking his own generous shaft while giving a sultry look to the viewer. In every image he looked so happy, just like how you wanted.
What? Keith struggled to focus his mind, processing the information overload. That last thought hadn’t felt like him, but it was nothing to worry about, was it? He just needed to bear through it and be happy like a good Asriel and accept how happy his body feels. No! That wasn’t right! He wanted to be happy and smiling like Asriel and enjoy everything that was happening to his body!
Bombarded with the sensations writing and without, unable to identify what thoughts were his and which were injected into his consciousness, Keith struggled.

Later. No knowing how much later, but later. The tickling had gotten worse. He couldn’t rest, not while his body was buzzing like a dynamo. More sensation had been added. A feather across his belly, tendrils along his arms, even a rhythmic brushing against his scalp that made his thoughts feel like they were flying away. A stream of drool was running down the side of his gag, and his body twitched spasmodically against the restraints.
All this time the images and messages had never ceased. Asriel taking dick, Asriel masturbating, Asriel posing in a languidly submissive sprawl. Always smiling, always upbeat. So easy to be that way, just be Asriel.
It was getting harder to resist. But the finding blow was yet to come. Unknown to him a portion of the table had opened up, leaving his fluffy behind exposed.
The gag prevented him from making any noise but he still released an exhausted squeal as a metal probe pushed its way into his sensitive tail-hole. He grunted and panted, his visor showing animations and video of Asriel getting a gleeful backdoor butt-fucking, the thrusts synchronised to the movement of his own anal probe.
He could feel himself getting shamefully hard, despite the relentless stimulation all over his body his cock was still responding.Tragically as it turned out. The next moment what felt like a spinning array of soft bristles fastened across the shaft and sent a fresh wave of electric sensation right up his spine.
This was too much. Every nerve was screaming with sensitivity, but his mind was endlessly being flooded with horny sensations and reminders of how much he loved being a horny golly-gosh goat-boy.
He couldn’t see it, but he could feel the climax when it hit, his dick exploding with enough jizz to rain down on him in little droplets, soaking into his sweat stained fur. Despite everything, the sensation of release was wonderful, regardless how much of it was hypnotic influence or genuine dopamine.
His relief was short-lived. A second later the brushes against his cock started up again, even harsher in their efforts to milk him. How?! How was he still this hard and horny?! Was it because he was a good Asriel? His cock was still hard and eager. Whatever had happened had reduced his refractory period to almost nothing, already he could feel another climax rising on the heels of the last one.
As the brushes against his body spun faster and faster, as the headset pumped more and more depraved, happy-Asriel porn into his head, as his consciousness began to buckle under the weight of the stimulation. Keith Asriel whimpered into his gag.

“Hee… Hee… Hehee…” The whimpering breaths echoed through the gag, each one timed with a spurt from the goat-boy’s eager cock. The brushes had nearly all gone now, the probe had gently been pulled from his butt, the sensory cage around his member had been pulled away, even the rollers across his torso had retracted. Only the brushes against his paws were still active.
But they were enough. The goat was being milked far beyond whatever limits he had formerly possessed, his fur and the table completely coated with sweat and cum. The whole room was a mess, the scents of desperation and release mixed strong enough to knock anyone out.
But Asriel was still smiling, still watching. Oh golly he loved to watch! So much fun to be had rubbing one out for a crowd of adoring fans- HNNGH! His thoughts paused briefly as he shot another jet of spunk onto his sodden chest-fur. Being passed around by a group of studs, sitting in their laps and getting a sloppy cream filling from each one! Or taking another twinky boy just like him, licking him in all the right places until he was a needy puddle of lust and then spreading him wide with his pretty cock! HUFF!
Finally the last few brushes pulled away, leaving his body raw and tingling. The visor switched off and retracted and the gag was removed from his maw. The clasps that had been holding his wrists and ankles secure came undone, and for the first time the goat was free to move from the table.
He did not do so. He just lay there, panting, lewd fantasies flashing through his mind. Cock still spurting from the phantom sensation of being milked.
Finally, finally when it dawned on him that he wasn’t being toyed with anymore, he reached a paw down to try and steady himself on the table. HNNGH! The sensation was enough to make his dick jump and spurt a little dribble of pre. His paw pads were so sensitive, just like a good Asriel! Just touching something was nearly enough to make him cum on the spot, how good would it feel if…
He cautiously reached a paw down, hovering a moment above his needy stiffy, then grasped it.
“HYAAAH!” He couldn’t help crying out. White-hot pleasure shot through his paws and his cock, meeting with fireworks in his brain. Every touch was ecstasy, every release was nirvana, he was helpless to resist.
Without quite willing it his other paw snaked down and started circling his sensitive asshole. The dual sensation from front and back made his eyes roll. He wanted, he needed to use them, and be used just like a good Asriel.
As he settled into his rhythm, one paw pumping over his dick, another pumping into his backdoor, his mind permanently hopped up on overstimulated pleasure, the mechanical voice chimed in.
“CALIBRATION COMPLETE.” It echoed through the room.
There was a hiss as the room started to fill with pale blue gas. Asriel had barely the time to pump out two more climaxes before he collapsed back on the bench and fell asleep.
