Cat Scratch Fever: Sister Act

added 2 years ago A BM S

Elizabeth unlocked the back door of Purgatory, running through all that needed to get done before opening the bar this afternoon.

Emma's older sister, or rather half sister, was 35 and did not resemble her younger sibling at all. Elizabeth - or Eliza to her friends - was a plump MILF contrast to her string bean of a younger sibling. She had been a wild child, and gotten pregnant with twins at 17, and never fully managed to shed the pregnancy weight. They would joke that Emma couldn't gain weight because somehow all the calories just ended up going to her sister.

She carried in her outfit for the evening, a bright pink full body latex catsuit. Included was a matching pink heavy collar and leash. Keeping with Purgatory's theme, the sisters had found that Emma parading Eliza round the place on a leash, and then spanking her with a liquor bottle on the bar, was good for a couple hundred dollars in extra tips each night. It also invariably caused their adoring regulars to order enough shots of the liquor used for the spanking to empty the bottle.

As she entered the small kitchen, she smelled vodka and something else. Looking down on the floor, an empty handle of Smirnoff lay discarded on the floor.

Picking it up in confusion, she almost dropped it. The bottle was wet and very slippery, much moreso than it would be from just water. Sniffing her hand, it smelled almost like lube, with a hint of blackberry.

In alarm and confusion, she dropped her outfit and bags and hurried out into the bar proper. She stopped dead at the sight of two big Cat Scratch anthros passed out on the floor. Several more empty liquor bottles were scattered around them.

They were tangled up in each other's arms, a crimson and copper lioness, and an ebon pantheress. The red feline was on top sprawled over the other's massive tits, head resting in the valley of their cleavage.

Eliza's eyes were drawn to the lioness's copper latex almost dreadlocks. The length and color shot a cold jet of fear down her spine and kept her from fleeing. She looked around and saw flesh colored tatters by the bar. Walking over, her fears were confirmed as she saw her sister's trademark long red hair in the mess of shed human skin.

Looking back at the passed out behemoths, she noticed something that had been hidden from the other side. Poking out of the pantheress's plump cunt was the neck of yet another bottle.

Eliza's eyes snapped to her own left hand, still slightly slick from the residue from the bottle in the kitchen.

Mind ablaze with what had become of her sister and fear of her own infection, she stood frozen in place for long minutes. Ultimately she had to be sure. If that had been their juices on the bottle, she was almost certainly already infected.

Wrapping a bar towel around her hand, Eliza carefully approached the sleeping lovers. Slowly she grasped the bottle and pulled it free. With an audible pop it came out and the cat's slit squeezed shut.

She sniffed the dripping bottle... Lube and blackberry.

Eliza retreated from the bar room to her office in the back.

Her sister was a dumb rubber fuck beast. Eliza herself was probably a ticking sex bomb, one little cut away from trading her humanity and about thirty IQ points for a lifetime of mindless fucking.

She wanted to scream. After all she had done and built, her life as she knew it was over. She had fucking worked for this. Going to college as a single mother of two, bartending at her dad's shit hole biker bar at nights to pay for it. Turning her dad's failed business to a local (though controversial) landmark. She'd taken in her teenage half sister when their dad fled to Columbia his past caught up with him. She'd scraped up the money to buy back Purgatory after the Feds seized it. Through it all she raised her kids right. She was a literal genius and an inspiration, she fucking deserved better than this!

'LIZZY! Fire has tits now!' A deep but feminine voice filled the air. Eliza looked up to see the towering rubber feline that her sister had become. She was crouching, far too tall to stand upright in the doorway. Her massive handpaws were squeezing her ample chest. 'They're like totally bigger than Lizzy's. They were hiding inside, Lizzy didn't get all the boobies after all!'

Eliza almost smiled at that. When her sister had gone through puberty and never developed anything close to her older sister's DD's, they joked that Eliza had claimed all the breast genes in the family, leaving none for Emma. Rubberized, anthrofied, and bimboized; it was definitely still her 'little' sister.

The crimson cat entered the room. Lizzy realized she had trapped herself.

'Lizzy needs to taste Fire's pussy, Smoke says it tastes like yummy cherries.' With that the latex feline launched at her sister.

Eliza tried to duck, but her reflexes were far too slow. However either luck (or bimbo stupidity) saved her. The room was lit by strands of Christmas lights criss crossing the ceiling. Fire's powerful leap to vault the desk and pounce her sister took her high enough to catch the strand with her neck. Clotheslined, she twisted and flipped backwards.

The red lioness's bulk slammed down on Eliza, buckling her chair and crushing her to the floor. The feline's head came down and caught the edge of the desk. With a bang, she was knocked out cold.

Trapped under the bulk of her sister, Eliza quickly focused on herself, fearful that she might have been cut or scratched. Amazingly, she seemed to only have bitten her tongue. Spitting, she was relieved not to see any blood.

Fire's bulk proved difficult to shift. Eliza remembered one of the great mysteries of SkinSplit. When an infected transforms, they invariably grew much taller. With that growth, volume increases, mass increasing by the square of the growth. The new rubber anthros were usually five hundred to a thousand pounds, and no one could explain where that mass came from.

With determination, Eliza wiggled out from under the seven hundred pound dead weight of her sister.

She had to call for help. The plump blonde grabbed her purse and ran out of the office. She must have really chomped her tongue, it felt very swollen, filling her mouth.

As she turned the corner towards the rear exit, she saw a dark mountain filling the hallway.

Eliza slid and reversed direction as the pantheress launched towards her. She ran back into the kitchen. Her mouth was open as she ran and gasped for breath, she could feel her too large tongue hanging out.

Eliza whipped open the walk in freezer and slammed the door shut behind her. The freezer of Purgatory was unusually heavily built and had thick steel walls - possibly related to her father's long ago illicit business dealings.

Smoke's half ton bulk slammed into the door, which dented slightly but held strong.

Temporarily safe, Eliza reached up to her face. Her tongue was far too large for her mouth, hanging out over her lips. She realized there wouldn't have been any blood. SkinSplit infectees don't bleed when cut, they just start changing. A cut from biting her tongue wouldn't be any different.

She whipped out her phone, determined to use her last lucid moments to alert the authorities.

Her phone wouldn't unlock, fingerprint invalid. Glancing at her fingers, they were starting to swell as something grew inside her, distorting her prints.

She tapped the unlock code and dialed 911. Her face was starting to feel tight.

'911, what is the nature of your emergency?' she heard the voice of the dispatcher.

'Iah nuhh haaaaa! Ah pbbbbtbb bhhh.' Eliza stopped. With her altered tongue she couldn't begin to speak intelligibly.

'Hello? Please repeat.'

A long snout pushed out through her open lips, her mouth stretching wider and wider as it emerged. In the bottom of her vision she could see a black nose, her snout a pretty teal blue on top and white on the sides.

The rest of her body felt tight, ready to split like a hot dog on a hot grill. Eliza was horny too, a fire had been lit in her loins. her arousal already burned hotter than it had ever before in her life, and kept rising.

She dropped the phone and tore off her clothes. Her tits had left their old DD size behind, standing tight and firm, as if she had H cup breast implants. Eliza plunged two fingers into her needs sex, then three. Still not enough she clenched her fist and forced it through her increasingly elastic netherlips.

This was what she needed and let her focus a tiny bit. She tried to speak but found her human mouth was too tight around her muzzle. Reaching up with her bulging hands, she grabbed her lips and pulled.

Her old face pulled away, and she saw white solid rubber bangs fall down the side of her vision, framing her new animalic face. Her rear felt tight, like a balloon was inflating inside just above her ass.

'Lizzy... No, I... Lizzy needs help. Caught SkinSplit and like is turning all rubbery and stupid.'

With a pop, her backside blew out, ruptured by an enormous teal fox tail. It quickly surged to the length of her legs and a foot and a half thick at it's widest. It was solid and smooth, with a white tip.

'Like wow! Lizzy... No, I'm... a... A big booby butterfly. No, no butterfly. A big titty sexy fox lady inside me. Lizzy is the fox. Lizzy needs to say... But what does the fox say?' She struggled to remember what she had needed to do. Her thrusting fist had her on the brink of orgasm.

That last unfortunately phrased sentence was the final straw for the frustrated dispatcher. 'Very funny, I remember that old earworm. With everything going on in this town right now, I have zero time or patience for stupid pranks.' With that the dispatcher hung up.

The transforming woman clenched her fists, bursting the human skin which had been stretched too thin over her vulpine handpaws. They were teal on the tops, white on the underside, with black pads on the fingertips and and palm. Her fingertips ended in black claws, made of the same glossy rubber as the rest of her new body.

Lizzy dug her claw tips into the taut skin of her chest. Each pressure point opened a hole, which quickly widened as soft white latex flesh pushed out through the gaps.

Her old flesh parted down the front, revealing another surprise gift from SkinSplit. The new fox had a second pair of breasts below the first. The four pack of pillowy white rubber mammaries went from collarbones to just above her belly button. They spilled around her sides and partially hid her arms from the front.

Her thighs shed their human covering as her change completed. She stood on new big vulpine paws, and opened the freezer door.

The new fox could feel a rubber ponytail bobbing behind her, tapping her blue green rubber back. Her solid latex 'hair' was one white mass but very soft and movable. Two long bangs framed her face, the tips of which grazed the tops of her upper pair of tits. Her thick tail swayed lazily behind her.

Where Smoke and Fire had hard bodies with well defined muscles, Lizzy was plump and soft. Her midriff was soft, looking like the barest beginning of a baby bump. Her ripe ass, huge hips, and plump thighs completed the voluptuous hourglass started by her outrageously stacked chest. Only her shoulders and biceps hinted at the power she had under that softness.

Smoke greeted her with a huge hug. They squeezed tight, tits squished together. Their abundant busts kept them from getting their muzzles close enough to kiss.

The pantheress instead dropped down and pressed her muzzle into the vixen's juicy cunt to greet her even more intimately.

Lizzy caught a scent of blackberry from her feline lover, and licked some of her own juices off her hand.

Mint! Delicious.
