FratRat: Rodents of Filth

Written by: Eiji Otaka and Howler

Jack's chest was pushed into the sewer wall his ass being fucked from behind from his master as the two other ratlings looked on laying in a slime pile making out. Loud squeaking and moaning echoed throughout the sewers as the rats had their fun, Bryan and Kevin locked muzzles thrusting their slimy tongues down each others throats.

"Harder master....fassster!" Jack groaned wildly his tail whipping around at the rat king's feet.

"When I'm done with you your gonna beg me for more, all you'll crave is sex be it with men or women. This is your home now boys and soon we'll fill these sewers with our filthy subjects and take this town for our own." The vermin king hissed drooling past large buck teeth.

"Yessss...masterrrr..." Jack squeaked obediently.

Bryan and Kevin squeaked in compliance as well, thinking of the piles of filth and fur that would soon fill their grimy home. They continued making out, caressing each other's bodies and rubbing filthy junk into one another's fur. The distinct smell of trash mixing in with their rodent musk, had their lust rising.

With a squeaking moan the vermin lord filled Jack's rear with his mutative semen, coating his insides thoroughly with the mind-twisting spunk.

"Now my ratlings, it's time to see what new disciples we can gather," ordered the master rat, pulling out of Jack's tailhole as sludge-like cum followed.

"Just a little more masterrr.... Pleasssse.." begged Jack, but his sire wasn't giving into his pleading.

"You'll get more soon my ratling, but until then, have a treat," he says wiping a hefty glob of cum that spilled from Jack's rear and smearing the yellow fluid on his follower's muzzle.

Jack squeaked in thanks as he licked his lips of the vile cock cream, that for him was like a contaminated ambrosia.

With that done the master rat leads them through the tunnels, peering through the drains with vicious red eyes to see if any vulnerable prey were passing by. A small car was parked between a narrow alleyway with two shadowy figures inside, Jack slowly pushed away the sewer grate and slithered out with his brothers right behind. The smell of sex ran heavy in the air here and it appeared to be a lovers lane of sorts, twin moans filled the air as the vehicle rocked slightly.

"What should we do master?" Bryan bemused curling his long rat tail around his thighs, the vermin's noses twitching at the sent of fornication.

"Do what feels natural my ratlings don't question your instincts instead let them guide you!" The large rat king mused staying low to avoid being seen.

Kevin sniffed the air drinking in the heavy sent of copulation that hung in the air around them. "One male and one female my master, they will join us and know the freedom of the rats." The filthy minded youth sneered eyeing the car carefully.

"Yes their healthy and ripe my lord and so perfect for breeding!" Bryan added lapping his chops hungrily, all three rat boys cocks dripping and erect.

"Then go my children go, make your master proud of you!" The rat king squeaked out.

The beasts stayed low to the ground crawling on all fours to remain out of the humans sight, each creature careful not to arouse the lovers suspicion's. With expert deft and silence they open up a door to the vehicle, the young lovers don't even notice before it's too late.

Kevin grabs the male and pulls him off and out the female, quickly impaling him on his slimy ratcock. The girl lost her chance to scream as Jack scurried onto her, and stuffed his tongue down her throat before replacing the modest human cock filling her with an large infested rodent one. The human boy tried yelling at the furry creature violating his woman and sudden unwanted penetration of his ass, but Kevin covers his mouth with a cum-coated paw.

Bryan was quick to find a way to not be left out, and grasped the male's thighs as he swiftly took the human's cock into his muzzle. The shaft was slowly deflating from the shocking rap, but Bryan was sure that he'd bring the cock back to life and more.

"Yesss... You know just how to please your instincts my children. Breed them...Breed them into more vermin disciples to worship and praise me!" hissed the rat king.

" Yes sweet master I will take great pleasure in corrupting him, I will show him our ways as you have commanded my lord." Kevin squeaked causing the human to close his eyes in disgust, the human male's muscles unable to move leaving the boy paralyzed.

Bryan suckled and licked at the human's semi soft penis, he gummed and ran his long slimy rat tongue from his balls to the boys tip. "Mmmm...I can smell his sent changing, he won't be long now. How is the female coming along brother, is she leaking milk yet like a proper breeding rat should?"

Jack snickered drooling onto her ample chest, grinning widely he slipped his mutated cock even deeper inside the girl. "She will serve our needs well and give birth to many babies, a breeder for all of the males to use!"

The human male tried to resist after hearing what was in store for his lover, but the cock pumping into his ass we starting to feel good, in addition, so was the muzzle coaxing lust back into his cock. His body was ready to give in and slowly but surely he started grinding his ass into the mutant vermin's thrusts. Eyes rolled in their sockets as the musk from the come covered paw sent him into an ecstatic haze. His tongue lapping out and cleaning the fluids from the gnarled hand as fur dusted his cheeks and down his spine. Weird thoughts were drilling into his brain, thoughts of filthy sex with males and females, of breeding amongst trash and grime, of changing humans into sex crazed vermin. He couldn't even picture himself as human anymore as his body convulsed and mutated, cock growing a sheath and lengthening into a virile hard rat cock in Bryan's muzzle.

The girl was moaning in rising pleasure, her disgust waning as Jack rocked his shaft into her. The odor of his filthy rat musk was now compounding her lust, where before it had drained it. She spread her legs to allow him better access, her swelling cunt and thighs shading with vermin fur. Nipples stood firm as her furring breasts began to lactate, much to Jack's glee. He took a nipple into his muzzle as it stretched into a teat and began stimulating her mammary glands. She squeaked in pleasure and shock from the milking of her breast, and the thought of her providing milk only exhilarated her. She felt a corrupted need to breed taking root in her and moaned as the thoughts took on a mindwarping verminous quality.

Jack drank his fill of the transforming rat girl, sexy buckteeth and whiskers on prominent display. Fine grey hairs dusting over her nude sweating form stopping at the wrists and ankles, Jack cried out sharply as his balls released their mutated glory and he seeded her with his tainted spooge. "That's a good girl squeak for me embrace what you are, your free now bitch...free to fuck and be fucked!"

The female's moans devolved into long pleasured squeaks of joy, her feet warping into fleshy gray rodent foot paws. Jack locked muzzles with her letting her taste of her own contaminated rats milk, this drove her over the edge and drove any remaining human thoughts out. Her clit swelled to new heights as thick ooze like musk ran across her thighs, the two ratlings sexual fluids mixing together in a puddle on the pavement of the ally.

The male was now squeaking with wild abandon, his muzzle pushing out fully, furred with buckteeth. Kevin was humping his ass like no tomorrow and the male rocked in rhythm, feeling utter ecstasy as a thick hairless tail stretched out his spine and wrapped around the leg of the rat topping him. Grey fur covered his body thoroughly as it started releasing its own filthy musk. With his nasty handpaws he grabbed the back of Bryan's head and forced his muzzle further onto his vermin cock. His fuzzy balls churned constantly as they filled with mutative rodent seed, his hairless feet twisting into digitigrade foot paws with nasty yellow claws. With a powerful squeak, his balls pulled up and surged pints of tainted yellow cream down Bryan's throat. His humanity a thing of the past as the feral orgasm washed away its remnants. Kevin squeaked at the pleasure of the new ratling's tailhole gripping his cock, and he climaxed to pour gushes of his own corruptive fluids deep into the male's body and bowels.

The two former humans squeaked and reveled in their new being, embracing the loss of their humanity and the gain of vile rodent essence.

"Good... Good... You two will make pleasing ratlings. I'm sure you'll breed and corrupt other humans to our superior species well. And, you my dear," said the rat king indicating the female, "You will be but the first of many females to birth our kin." He then squeezed some milk from her lactating teat as if to accentuate her new purpose.

"Yes father I will birth many ratlings to the cause and all will grow large and strong to further our species, my milk is creamy and thick and no human will be able to resist it once they taste it." The she rat hissed out rubbing at her tits her snatch dripping thick fluids from Jack.

"Very good my dear now kneel before your master, feed and taste your king's hot filthy cum." The rat king chuckled with glee.

The female fell to her paws and crawled over to the king like the stunning creature of filth she was, her form was attractive to the males and her cunt sprayed musk as she slunk towards her father. "I'm sooo hungry masterrrr....please feed meeee!" She moaned low and needy.

She quickly licked the pre dripping from the tip of her master's feral cock, enjoying the taste of the corruptive fluids on her palette. Without a hint of coercion, she took the foot long shaft into her muzzle, wrapping her slimy tongue around the vile shaft. Bobbing her head up and down the rat phallus sent a deep pleasure through her, the joy of being a rodent breeder slut to the core showing itself. She felt pride whenever the rat master squeaked in delight at her fellatio skills. Every bob of her muzzle shoved the pre-leaking tip into her throat, and the pull of her esophagus on the rat king's cock made his balls churn in anticipation.

The other ratlings were stroking each other and groping themselves as they watched the master feed the rat bitch. They hungered for sex, and they hungered to feed of his penile nectar themselves. Clawed paws stroked one another and their own cocks as the males slowly sank to the ground jerking themselves squeaking out nosily in the ally way, the slimy fur coats of the rats reeked of waste and trash like a land fill.

"Quickly my children we must retreat to our den before we're spotted, I do look to the day when we may roam openly in the sunlight!" The vermin king moaned aloud as powerful jets of yellow rodent jizz filled the female rat making her cheeks puff out.

"Yessss fatherrrrrr.....lead the way." The she rat groaned opening her newly minted rat's eyes to gaze up at her creator lovingly.

The rat king scurried back to the manhole with his vermin disciples closely following. They could sense they joy he felt at their numbers increasing. Taking to the sewer tunnels, they basked in filth while waiting for the opportunity to corrupt more of those disgustingly clean humans. To further this point, they rubbed dirt and junk all over each other's bodies as if giving baths, taking joy in the increasing pungency of their vermin musk as their sweat mixed with the filth. Bryan going a bit further in his actions, by taking a nice grungy pile and rubbing it into his furry ballsack, squeaking all the while before shooting jets of yellow cum all over his brothers and sister.

"My children the best is yet to be, we will strengthen our numbers until we can walk the surface and be free." The king hissed his disciples joining him.

"Yessss masterrrr....." The five rodents replied in chorus, the take over had begun.

The rat's began an orgy that night of which the squeaks could be head in every manhole and sewer grate in the city, even the normal rat populous stood watch at the sight of the fur and tails slithering before them.
