#37 of Transformation Stories

A little solo adventure of Orel down in the Cistern, obeying his MC's instructions as he tests out some new equipment.


Wandering through the Cistern as Orel always felt weird, the brown rat padded bare-foot across the mesh-floor of the main room toward the new rooms the MC had built. Pausing the brown rat looked around the room and grinned; he had to admit he loved it down here, assuming the persona of the Sewer rat, spending days indulging his kinks and sexual desires with a willing friend; it was great and paid well.

Today however he was here to see the new systems the MC had installed, they wanted to expand their offering to the members. They loved the watersports, the humiliating games Sewer played with his pets but some local polls had flagged up some areas they were lacking.

Ducking through the new doorway built into the wall of the Cistern Orel looked around the clean tiled room beyond. There was a shower alcove, a few cabinets for cleaning materials but the centrepiece of the room was a large reinforced glass cubicle. There was a handle on the outside but nothing on the inside, just four large spouts in the ceiling and what looked like chains and equipment for stringing someone up by their wrists. It was also about five feet wide so it wouldn't be a snug fit, in fact it was more than large enough for two people to move around in.

"I like what I am seeing," Orel said softly as he walked around the cubicle, "What's it for? Mud? Piss? Gunge?"

"Gunge," a voice murmured over the intercom, "The thick, colourful kind, also sometimes called slime."

Orel grinned and walked around the cubicle, peering inside then ducked through the arched doorway on the other side of the room into a tiled room with a sunken, sloping floored pit in the middle of it, "And they really want to see me fucking and playing and teasing my pets in this mess?"

"Yes," the voice of the MC said, "Is that a problem with you?"

"Hell no," Orel laughed and looked up at the nearest camera, "You know me, I love being a mess but this seems pretty tame for us."

"Not quite as tame as you think," the MC chuckled, "Some of our VIP guests want more chances to interact with Sewer and his pets, see the hatch on the far side?"

Orel walked down into the currently empty pool and examined the hatch, the tiled wall was designed to open and as the rat touched it the wall slid aside. A tiled corridor, with cameras and cleaning apparatus built into the walls and ceiling lay just on the other side. The deep channel he was standing in was flanked by a narrow walkway, much like a sewer tunnel and split into different tunnels up ahead.

Orel laughed and pulled himself out of the channel to look along the corridor, "You built me an actual sewer? Albeit I've never seen one as well lit and fresh as this one."

"I did," the MC said through the speakers, "We've made enough profit from your shows and some of our ideas at our last planning meeting sounded fun."

"Bet you can't wait to sit up there pawing off to them," Orel teased, squeaking softly as he walked along the sewer a short way, "So I'll be let loose in the sewer to hunt down guests or people our VIPs have nominated?"

"Yup, everyone in the sewer will be being expected to be hunted by you and your current pet. They'll know the penalty for losing is probably to get humped or pissed on or even transformed by you."

"Sounds fun," Orel chuckled and moved back into the main tiled room, "Is the sewer going to be full of piss or gunge or something else?"

"Still planning that," the MC said, "I think it'll depend on the theme of the night, we can fill and drain and clean the sewer in about an hour so we have options."

"Nice," Orel chuckled, "You know I'll dive head first into anything if it means I get to be a mess and have sex," the rat laid a hand on the glass cubicle, "So what's the other catch for the gunge?"

The MC was quiet for a moment and Orel looked up at the cameras and grinned, "Come on, I know there has to be one."

"You're right rat," they chuckled, "But fine, turn into that hot skunk boy of yours and get in the cubicle."

Orel nodded and pulled off his T-shirt then slowly, swaying his hips for the camera as he pulled down his shorts, underneath he was wearing a dark green wrestling singlet. The rat preferred to wear the tight, clinging lycra beneath his clothing instead of regular underwear. As he reached for the straps over his shoulders, the MC ordered him to leave it on and he obeyed.

Many people assumed MC stood for Master of Ceremonies but Orel was clued in, it stood for Master of the Cistern and Orel had happily knelt and proclaimed the mysterious figure his master. The rat obeyed without question any order given by that smooth voice, he'd spent six months being trained by them before his debut as Sewer and he loved and trusted them like no one else. Dressed in just his tight singlet and collar Orel accessed the holographic controls for his collar. His species wheel waited and the rat selected one of the secondary species in the green allotment.

The change was as always electrifying, the collar retracted about his neck, squeezing his throat. Orel watched himself on the screen that was playing the camera feed, of course the MC would start recording this. The strip of polymer turned from bright orange to a deep, dark emerald green. The next step was his eyes, the flashed, changing colour to match his collar, accompanied by a jolt of pleasure deep into his brain that made him groan and the front of his wrestling singlet start to bulge in excitement.

From there the changes came quickly, black fur spread down his body, from the underside of his muzzle, to his crotch. It swept along his legs as they grew longer and his shoulders broadened, hands bristling with dark fur instead of pink skin. His whole build was changing, taller, broader, heavier and white fur engulfed the top of his head. Swept around his eyes in a skull-like mask then raced across his shoulders and formed two stripes along his back before merging again to forge a thick stripe along the length of his huge, fluffy tail.

He was Orel, he was a skunk, a good six feet tall, broad shouldered but lithe, willowy, his upper fangs larger, completing the skull look as he braced himself, one paw pressing against his thick, rock hard cock as it stretched his singlet, this next bit was always so intense.

Piercings, he'd not understood they could be recorded as part of a shape. But the collar was using nanites, his body was infused with them. So it was a simple thing, cold metal bloomed in one ear, a plug of green metal with a black filling etched with the chromatech sigil. His other ear received a bar whilst a ring of green metal grew to hang just so from his nose. They felt good but the ones that did it every time, that drove him to his knees were the studded bars sliding into place along the underside of his cock!

It was hard, uncut and he didn't have a sheath like this, the piercings sliding up the length of his cock in a ladder felt amazing. There were six of them, one by one his collar put them in place until the final small ring slid through his frenulum and he started to cum. He moaned, leaning backwards, soaking his tight lycra clothing, the cum trapped between the stretched fabric and his fur. This just made his twitching cock rub his piercings against the taught material and left the skunk gasping and riding his orgasm for longer.

"That's a keeper, a VIP video if ever i saw one," Orel's Master purred through the microphone, "Take a moment skunk then climb in the cubicle, we're only just getting started, it's time I showed you what the Grunge Pit can do."
