The taxi pulled up outside Dion's house. He paid up and stepped out, followed closely by his date for the evening - a cute pink bunny named Sleepey.

Sleepey took one look at the place and gasped. "Dion, this place is huge!"

"Eh," the human shrugged. "It's alright."

"Are... are you taking the piss? Look at it! It's like a- a straight-up mansion!"

Dion just laughed and led the way, through the fancy gates onto the grounds. He heaved open the front door just enough to let them both inside, then slammed and locked it shut behind them.

Sleepey looked around the foyer in awe. He'd never dated anyone with a foyer before. How did he not realise he was on a date with a rich guy? It should have been obvious with hindsight - so flashy and groomed, not a hair out of place on his perfect head. Maybe a little too much cologne...? Well at least now he felt less guilty about letting him pay for dinner.

"I'll take your jacket," said Dion.

"You back already?" A large silhouette appeared on the landing upstairs.

"Yeah," the human replied. "Brought him home. Could you run the bath for me?"

"Sure."

Sleepey blushed at the idea of a little wet play with his date. "Is that your roommate you mentioned?"

"Yeah, his name's Ward. I'll be back in a sec, don't fight him."

"F-fight him?"

Without another word, Dion vanished into the cloak room with their jackets.

The roommate descended the stairs, revealing himself in the light - a brown rat, at least 7ft tall and clearly obese, wearing nothing but a pair of boxer shorts. Each step landed with a thud that rippled through his big round belly. He approached Sleepey, but his odour arrived before he did - a thick, ripe musk he must have been stewing in for days.

Poor Sleepey could do nothing but stare, mesmerised first by the rat's jiggling gut, then by his piercing stare, and finally by his hardening cock, tenting his shorts unabashedly.

"H-hi," squeaked the rabbit. "I'm Sleepey."

"I know. Turn around."

Sleepey gulped and complied. With his back turned he could only guess from the sound what was going on - fabric rustling, grunts of exertion. An alarming amount of slapping and squelching.

"May I ask... what you're doing?" he said.

"Running the bath."

The rat grabbed Sleepey by the head - a meaty, greasy paw clamped across his face - and yanked him backwards. Downwards. Toppled him onto the waiting tip of his oversized cock, and with a gentle grinding motion began to press him inside the slit.

No chance to react, no resistance but a muffled yelp, Sleepey struggled to comprehend what was happening to him. He kicked and thrashed but only managed to push himself deeper.

Wrist-deep in his own urethra, the rat let go of his prey's face and pulled his hand back out. The opening sealed shut around the rabbit's neck. Next, he slipped his hand under Sleepey's butt and hoisted his body into the air. Gravity would do the work from there, pulling him down, deeper into the rodent's hungry shaft.

Sleepey hacked and spluttered at the fluids invading his every orifice. He tried to shield his face with his big bunny ears but it was no use, the rat's precum permeated everything. The tight, fleshy walls massaged it into his fur and skin, lubricating his body, allowing it to be consumed ever faster. Within a few moments though, a few slimy mouthfuls later, something changed in Sleepey. It got to him - the taste, the stink, the suckling, the squeezing. He stopped all his coughing and kicking and just... swallowed. Savoured. Salty and sweet. Liquid lust, soaking him through. As the alarm bells faded away he started writhing again despite himself, not in fear but in pleasure.

Then he reached the bottom.

As his ankles sank into the tip, his head reached the base of the rat's hyper-sized cock. The tube curved sharply upward, toward the rodent's belly. Now Sleepey was grateful for being told to turn around - he wouldn't have been able to bend like this the other way. This part of the tunnel was different. A little less slick and a lot less sweet. His head bumped into something, but the motion of the tunnel walls kept pushing him forward. The blockage - a sphincter - gave way to the pressure and Sleepey was slowly forced through to his destination.

The rat felt every inch of his prey's journey. He watched the rabbit's feet disappear into his cock, the slit closing up behind them. And he sighed. That was the easy part.

He made his way across the hall, dragging his rapidly-softening but still absurdly long penis beneath him. For each step he took, a little more of the fully-grown man inside him forced its way into his bladder. His belly seemed to be growing before his eyes. He waddled through a door, passing from the immaculate lobby into a rather less-than-immaculate bathroom. Damp and yellowed, strewn with dirty laundry, with a thick layer of shed hair over every surface. Ward sat on the toilet to rest his legs.

A short while later, Dion entered the bathroom wearing nothing but an old bath robe, tattered and stained. He laid his hands on the rat's bulbous body and kissed him on the nose.

"Nearly ready?"

Ward nodded and hoisted himself to his feet with a grunt and a slosh. "He settled quickly."

There was nothing left of Sleepey inside the rat's bladder - at least, nothing solid. The poor bunny had been melted down, his body stripped of its form and leached of its nutrients, until all that remained was water and waste. Urine.

Ward waddled over to the bath and pointed his cock over the edge. He took a deep breath and closed his eyes. The piss shot out of him, deep yellow, splashing and roaring against the opposite side of the tub. A jet so hot, so forceful, it could strip paint.

The acrid smell of it reached Dion's nose and made his dick hard then and there. He groped himself through his robe as he watched the rat drain his bladder into the bath, that bloated belly shrinking before his eyes. With a long sigh he snuggled up by the rat's side, brushing his cheek into the rat's thick, grease-slick fur.

"You should try being the bait some time," he said, chuckling at the thought. "Get you cleaned up, find you a nice suit..."

"And what would you do when I brought them here? I'm not doing both jobs."

Dion unfastened his robe, revealing his lithe, pristine human body. "Mmm... I'll think of something."

He stepped into the half-full tub and felt the warm, soothing liquid between his toes. Kneeling slowly, the steamy piss engulfed his legs, lapped at his crotch, crept up his backside. He washed his hands in the filth and ran them through his hair, perfect no more. Then he looked at the rat through lidded eyes, and nodded.

With only a small movement of his hand, Ward pointed his gushing cock at Dion's chest. The human recoiled at first from the sudden force of it, but soon began to enjoy it, as he always did. Squirming and moaning under the shower of waste, rubbing it into his skin, basking in the stink. It was running clearer now, a lighter shade of yellow than the initial blast, but it was still plenty potent.

Dion reached out and snatched the rat's dick out of his hands.

"H-hey!" yelped Ward. The surprise made him clench and the flow slowed down for a moment. "You're not usually this... grabby."

Dion took no notice, his full attention centred on the thick, vibrating ratcock in his fingers, urine pouring from the tip like a riot cannon. He aimed it down, just below his chin, and gingerly lowered his mouth into the flood.

"Mmph!"

Instantly overfilled. He turned away to swallow what he could and regain his breath.

"How's it taste?" said Ward.

"It's uhh, interesting." Dion licked his lips, savouring the flavour. "Salty of course, but not as bitter as usual. Maybe even a little sweet."

"You mean...?"

"Yeah, no fear. I think he even enjoyed it."

Ward laughed. "You pick up the weirdest guys sometimes."

Dion sat back in the tub and stretched out. The piss nearly covered his chest now, the stream slowing down to something a normal person might produce. He stroked his own cock a few times beneath the surface, not taking much to push him to the edge.

"Hold on," said Ward, grinning. It was his turn to get grabby.

The rat squeezed his last few drops into the bath, then leaned over and dipped his nose into the waste, clamping his mouth over Dion's dick and sucking on it hard. First gulp, he swallowed a mouthful of his own piss. After that, glob after glob of thick, fresh cum.

"Oh my GOD Ward!" Dion screamed. In a mixture of shock and orgasm he thrashed his legs around, flinging urine everywhere, and accidentally snagging the plug chain with his toes. A loud gurgle erupted from the drain, and the former bunny's remains began to swirl away into the plumbing, never to return.
