Welcome back to the Cistern

Tonight's show involves our delightful rats doing what they do best


Toilet squirmed as his master fixed the clips to his wristbands, chaining him in place against the mesh floor of the Cistern. He was down on all fours, palms flat against the plastic coated grill that kept them out of the drain itself. The yellow rat's legs were also bent in the right way to let him keep his feet flat as Sewer moved back to secure his feet.

This body he was now living in was mostly anthropomorphic, but had clearly been designed to make it easier for him to crouch on all fours like this. He wasn't quite sure what was in store for him but after last night's amazing time in the tank he was ready for something a bit less intense.

He'd been in the tank for about eight hours, by the end of the sixth he was entirely submerged, trapped, tied down, floating in all that piss! It had been so humiliating but at the same so very, very horny. At the end of the evening Sewer had climbed into the tank, naked, hard, wearing just a breathing mask and set about humping Toilet there and then, Trapped in his suit, floating beneath the surface with his Master's cock riding in and out of him Toilet had been in heaven. Add to that the fact he knew the occupants of the club were up there watching him it had been amazing. Despite the cage holding his cock imprisoned he'd cum, or at least experienced orgasm as he was filled with Sewer's seed once more.

After that the screens had turned off, the tank had been drained and the smaller rat had been released from his prison. Of course Sewer had been a mess, he wasn't just damp with piss he was soaked, entirely and he stank and had still been horny. They'd both wound up putting on one final show in the showers, Toilet finally got to cum properly, sitting atop Sewer as the big rat lay on his back and showed off Toilet's eager pawing to the cameras.

It had been a huge orgasm, the smaller rat had poured hours of pent up rat-cum all over himself, Sewer and then been given permission to let go as well! He'd emptied his bladder all over Sewer whilst his Master fucked him and the screens recorded the whole wild, desperate, eager, piss soaked session for the patrons upstairs. After that neither of them had the energy to clean up properly, they'd just sat in the hot water cuddling for a bit then slept in the nest.

So far today had been pretty sedate, they'd slept in really late, eaten brunch and now Toilet was being tied down right over the central drain. He let out a soft, squeaking groan as his Master finished, clipping his tail to the back of his sleek, black polymer collar. Panting excitedly at being so methodically restrained the yellow rat felt his cock sliding free of his sheath. It slipped between one of the larger gaps in the mesh and he moaned as he caught sight of himself on the screen.

Trapped on all fours, tail hiked up to expose his rump and balls, cock hanging free and eager below the floor, dripping pre-cum right above the drain. Satisfied with his work Sewer moved to mount him, that long, tapered rat cock nudged up beneath his tail and with a happy, rumbling squeak the bigger rat started to settle himself down into Toilet's warm, inviting rump.

The rat groaned in delight, pushing back as best he could, clenching around that shaft as it slipped into him, then relaxing to let it be drawn back out only to be driven home once more. Inch by inch Sewer worked more of that length into his rump and Toilet moaned and squealed in delight. His clawed paws opened and shut in time to those thrusts, stretching, curling, tensing with each clench only to uncurl as he relaxed and let Sewer pull back out. It felt so good, he knew he was being filmed, that people upstairs were probably watching this, getting off to him being fucked like this.

It was still a massive turn on, Toilet needed that, wanted to know he was being watched, being admired, being toyed and played with by the big rat and the mysterious MC who over-saw their lives. He was aware that at any moment the shower would start, the deluge of warm piss that would rinse down over them, once again putting them both Master and Pet in their place as sewer rats. But the deluge didn't come, Toilet was left squeaking, gasping, feeling his own nuts drawing up closer to his body, he was being toyed with, played with expertly, his cock was twitching, leaking pre in a near steady stream!

Sewer was speeding up, panting heavily, leaning forward, sliding his hands down Toilet's arms, gripping his hands, resting his head atop the smaller rats, that long, luxurious goatee sliding over his muzzle. Sewer rumbled, squeaked, thrust home and held still as his cock twitched once, twice and then started to fire thick ropey jets of his sticky seed deep into Toilet's rump. He moaned in delight, pleasure coursing through his body at being filled and as he lay there, enjoying the warmth of Sewer inside of him he felt his own body balanced, right on the edge, he needed to cum, wanted to cum.

But he had enough sense to tilt his head back and whimper, "Master, can I cum?"

Sewer rumbled, remaining quiet for a moment before murmuring, "Only whilst I use you as the toilet you are meant to be."

Toilet's eyes went wide as he felt a new rush of warm liquid flood his rump! It swirled deep into him, forcing his insides to stretch as Sewer released his bladder into him! It was too much, eyes popping wide open the smaller rat let out an ecstatic cry and started to cum! His cock twitched, jerking against his stomach and the underside of the mesh floor as he spilt his seed down over the drain. Panting heavily the rat rode his orgasm out, that flood of piss still filling his rump and started to ooze back out around Sewer's cock and spill down over their furry legs and balls.

Only as his orgasm drew itself to an end did the shower start! Not a deluge like normal, but a fine falling spray that splattered down across their fur. Without even thinking about it Toilet tilted his head back and started to drink. A thrill ran through him as he saw that Sewer also had tilted his head back, even as he continued to empty his very large bladder into Toilet's rump. They were toilet rats through and through... he couldn't wait to see what they got up to next.

After lying happily for a while, cuddling and just steeping in piss, their fur soaked and slick Sewer got them both up and into the showers. Rinsing out their fur, using shampoo and conditioner and brushes the pair had grown quite adept at helping to clean each other up. They took longer than necessary in the hot water then retired to the kitchen to eat dinner and relax a bit before the evening show.

Toilet watched with interest as Sewer crouched near the centre of the mesh floor and gripped it with his claws. His muscular body strained for a moment before with a metallic clank, a circular patch of the floor rotated. He then heaved the whole section of floor up and slid it out of the way then hopped down onto the slick concrete surface of the drain. Moving up to the edge at his gesture the smaller rat let his Master help him down and watched curiously as he walked down the slope to the large drainage hole.

Toilet followed and peered in, expecting to see a blockage or something, but there was just a five foot hole then a mesh grill before the hole narrowed further into a proper pipe. "What are we looking for?" Toilet asked curiously then yelped as Sewer wrapped his arms around the smaller rat's waist and lifted him down into the drain.

Toilet squeaked and gripped the side of the concrete hole then gasped as Sewer clambered down after him. The bigger rat's shoulders and head poked out of the hole but Toilet's chin was barely above the rim.

"We aren't looking for anything Toilet, turn around and face me," Sewer said in that deep voice of his, making it clear it was an order, not a suggestion. Sliding around to face his master Toilet blushed at the tight confines of the hole that pressed their bodies together.

His sheath was resting against Sewer's balls whilst his master's cock, half hard and eager pressed against Toilet's stomach. It was a tight fit in this hole and Toilet wasn't entirely sure why they were down there but after a moment something descended from the ceiling. It was a clear pipe and fixed to the bottom of it where two bronze muzzle gags.

Sewer slipped an arm out of the hole and reached up to pull the contraption a bit lower then held out one of the gags to Toilet with a wicked grin on his face, "MC wants us to be urinals tonight, but I won't force you Toilet, you can climb out of this hole and go rest up in the nest, I know it has been a full on schedule so far, you might be sick of piss."

Toilet blushed, his ears growing red, Sewer had just handed him an out, he could climb out of this drain, go lie in the nest. Spend the night dry and not drinking the piss of every member of the club who had to take a leak. Squirming a bit, his body rubbing against his master's fur, his rat cock growing thicker in its sheath Toilet took the bronze coloured gag, slipped the cock shaped mouthpiece into his muzzle and tied the straps behind his head, pulling the latex muzzle covering tight. It forced his mouth shut and by the time he was done his cock was rock hard and pressed against Sewer's furry body.

"Good sewer rat," the big blonde rat murmured, "I knew you wouldn't let me down," he took hold of his own gag, but paused a moment before putting it on, "You can relieve yourself and cum whenever you want tonight, since I won't be able to give you orders."

The big rat then slipped his own gag on, tying the straps tight behind his head to hold it in place leaving Toilet's master with no choice but to drink all the piss that came down the pipe as well. It was odd thinking that his Master would be suffering the same fate as him. But then as he kept being reminded they were both sewer rats, even if Sewer himself was in charge.

This setup was clearly as alluring to Sewer as it was to Toilet, the smaller rat could feel his master's cock pressed up against his furry body and he had no restraint, humping his cock up and down through Toilet's soft fur. He grinned down at the smaller rat, red eyes twinkling in delight then looked up as something gurgled above them. Dark yellow liquid poured down the pipe and then flooded Toilet and Sewer's muzzles, the flow split between them as it funnelled into each rat's mouth. Both of them started to swallow, gulping it down, grinding and humping against one another as they had no choice but to be urinals.

As their first drink ended there was a loud clunk and piss started to wash down the far walls of the cistern! Pouring out of the pipe system that usually managed the cleaning each night. It was quite a torrent, pouring down the concrete walls, the pipes angled to cause the water to swirl around the sloping drain rather than flow straight toward the drain. The wave of rich, musky piss whirled around them before crashing in a wave into the hole Sewer and Toilet were standing in. It soaked them and added an extra layer of needy, horny squirming to their desperate humping, wriggling need. The drain was too small for them to paw off in, all they could do was hump against each other and as the wash of piss continued to soak their bodies more piss started to flow down the pipe, forcing them to drink.

It was going to be a long night, a horny night as both Sewer and Toilet were reduced to little more than squirming, horny, piss soaked urinals for the pleasure of those watching them upstairs.
