At first, it was imperceptible, looking like nothing but a few unusual cases of septicemia. It crept across the globe, and by the time doctors even realised it existed, it had infected 98% of the population.

The remaining 2% lucky enough to be immune were evacuated to Taiwan. The new cradle of humanity, they called it. Even as the dying begged for aid, the remaining authorities said they were devoting all resources to the immunitas, for the sake of mankind's survival.

Fuck mankind, Izz had thought.

It works like this: you can't know you're infected without being tested--and there's nobody left to do that now. You can be spreading it for years without noticing. Then one day your number comes up; your blood turns to poison and your organs liquefy. Then you die in a pool of your own filth. The oldest anyone had made it, as far as Izz knew, was 35.

Medical research stalled. Virology took forever to learn; everyone who tried died before making themselves useful. People were still trying. Izz thought they were stupid.

From her living room window, Izz could see an altercation unfolding. Some kid from down the street lay on the asphalt at the mercy of his older brother. She watched with slight interest as the bigger sibling choked his brother to death.

It wasn't uncommon for older siblings to kill the younger ones. Staying alive was hard enough as it was, without having to worry about all those little shits. It wasn't a good idea to get too attached to anyone, anyway. Everyone's about to die, always.

She did love her little sis Monica though, in the same way one might love a prized pet.

Besides, the girl was a chick magnet.

Izz picked up girls nightly, without fail. Usually, she'd watch someone glance down at Monica, and then up at her, looking for whoever owned the fuckable 8-year-old. Luckily, Izz was cute too. Her sister was the bait, and then Izz would reel them in.

Izz kept Monica clean: plucked her eyebrows, scrubbed her cunt, cut her hair and slathered her head to toe in strawberry scented moisturiser. She made Monica work out too, her little ass had to stay perky, and her stomach taut. She looked delectable.

She was usually naked--at Izz's insistence--and always by her sister's side.

Izz never killed her dates without asking first. Unless they were men. She wasn't into guys, not that it much mattered what you were into, in a world that had largely forgotten the meaning of consent. Izz had a reputation, though. The last guy who'd tried something ended up choking on his own balls.

At this point, Izz lived for the sex and the killing. Especially the parties. Even with the world in the state it was, most people minded their own business and didn't cause any trouble in public. The parties were different.

Everyone attending understood that nothing was off limits. Nobody cared if you died, got raped, or both. It was up to you to defend yourself, if you could be bothered. Plenty of people went there to die for fun, while others relished in taking lives. Izz was a little different, she sought human connection. She slaughtered her lovers, sure; all her relationships had ended that way. But she liked that look in their eyes, that grateful gaze that said 'thank you for letting me end it with you.'

She'd share her sister with them too. Izz smiled fondly at this, remembering her sister eating her last girlfriend's ass. That night had ended with Izz licking her deceased lover's still-warm blood from Monica's cunt. It was a fucking beautiful mess.

Tonight was going to be another good night. Some of her friends had converted an old warehouse into a bar after finding a bunch of liquor stashed away there. They'd even appropriated the old overseer's office as a private room; Izz was invited, of course.

Sister in tow, she arrived at the warehouse around 10pm. She glanced around briefly, admiring the sea of half-naked revellers. There were plush leather daybeds dotted about the room, most of them occupied with writhing lovers. She watched covetously as a twenty-something redhead plunged a razor-sharp blade into the cunt of a tween with the same auburn hair, the kid's screaming rising above the din . Sitting beside the dying girl was, presumably, her little brother. He looked about ten. His little cock was throbbing, and Izz could see apprehension and excitement in his expression. She marked his face. If he were still alive later she might do something about that.

By the time Izz managed to drag her eyes away from the redheaded family, Monica had vanished into the crowd.

Stupid little shit.

Izz shrugged and pushed her way through the crowd, up the industrial staircase and into the converted office.

Everyone else was already here. Jess, Sophie, Alice, Farah and Erica.

Jess was absentmindedly slicing her thighs with her favourite pocket knife when Izz walked in

"Hey," Jess said, smiling sweetly.

Izz returned the greeting, feeling a rush of arousal as she admired her naked friend's tits, stomach and bloody thighs.

"Where's Monica, then?"

Izz sighed, "she fucked off somewhere."

"She's fucking dead then," Jess said, laughing.

Usually if someone saw a child was spoken for, they'd respect that--at least early in the night. An unaccompanied kid at a party like this, though, was just asking for it.

"Oh well. She's a slippery little fucker. If they can catch her they can have her," Izz said, taking a seat on the couch next to Erica.

"Hey beautiful," Erica said, putting her arm around Izz.

Erica was a trans girl, and as hot as any of her friends. She was girl enough for Izz, that was for sure. Izz grabbed her girl-cock, which had been standing at attention since she arrived. She stroked it gently as they spoke.

"Your tits are looking great."

Erica beamed. "Thanks! Marc found a huge stash of hormone drugs at the pharmacy near his parent's old place. I have enough to last me a lifetime."

Sophie, Alice and Farah had not paid Izz any mind. Sophie looked catatonic, sitting in the armchair opposite her. Izz saw that she had pissed herself at some point earlier in the evening. Alice and Farah were busy fucking on a nearby bed. Farah was a middle-eastern beauty, with her smooth dark skin and hair the colour of treacle. Her breasts were an immaculately perky b cup. She was celebrating her 17th birthday with Alice, who was buried between her thighs. Alice was a little butch, but only in comparison to the rest of the girls Izz hung out with. Alice had a feminine face: big blue eyes with long lashes, and full lips. She kept her jet black hair in a short pixie cut. Unlike her relatively hairless lover, Alice let her armpit hair grow freely, and she had a substantial but well-kept tuft of black public hair. She was somewhere around 25--old by today's standards. This was no detriment to her body, though, with her weighty C cup tits and a big, firm ass that Izz couldn't help but appreciate.

"I think Sophie's gonna go tonight." Jess said, breaking Izz's reverie.

Izz looked across at the petite girl, unconscious in the armchair. "Yeah, she's probably fucked her brain with whatever she's on."

Jess nodded, "she'll wake up, I think. But she'll have lost some IQ points."

Indeed, she had just woken up.

"H-hey Izz," she said, eyelids half-open. "God, I'm so fucking wet."

"No," Izz laughed, "you just pissed yourself."

"Oh," Sophie said, as she considered this for a moment.

"Did I fuck up?" she asked.

"Uh-huh," Izz replied.

"Fuck," said Sophie, drool spilling from her lips, "I can't remember where I fucking live."

"It's okay," said Izz, whispering, "I'm gonna do you right now, you don't have to worry."

"Y-yeah, Oh. Okay," Sophie said, stuttering. She didn't know if she wanted it, but her now useless brain didn't offer her any good alternatives.

Izz kneeled down in front of Sophie. She could smell her cunt, and the stale piss that had soaked into the upholstery.

"Hey, Jess, pass me your knife."

Jess threw her unfolded blade to Izz, who reflexively caught it by the handle.

"Ha ha, funny," Izz said dryly.

With her left hand, Izz shoved two fingers into Sophie's cunt and pressed uncomfortably hard against her friend's g-spot. This made Sophie arch her back, presenting her soft stomach to Izz, pale flesh flushed with arousal and fear.

With her right hand, Izz gripped the blade tightly.

Sophie moaned from the pleasure of Izz's fingers intrusively probing her cunt. Then, she screamed as Izz forced the knife into her belly just above the pubic bone, and yanked violently upwards. Sophie vomited all over her tits and on Izz's face. She moaned again quietly, this time in defeat. Izz smiled gently.

"Good girl," Izz said.

She put the knife aside, and worked her right hand into Sophie's belly. Izz found the exterior of her dying friend's cunt and squeezed it tightly.

Sophie made a noise somewhere between ecstasy and agony.

"Don't wanna die," she said, almost silently.

"It's okay," Izz said, now stroking Sophie's sex from inside her ruined belly.

"N-no, not..." Sophie whined.

"Shhh." Izz removed her left hand from Sophie's cunt, and stroked her cheek. "It's just taking a little nap. You know when you cum and then drift off? Just like that."

This had the intended effect. Sophie calmed down and let the inevitable happen.

Within minutes she was dead. Izz scanned dead friend's body. Her little tits were covered in puke and sweat, and below her chest were a mess of intestines spilling from her ruined belly. Finally, Izz admired Sophie's still moist cunt. She leaned in and licked her friend's sex, savouring the last taste she'd ever have.

Izz closed her eyes, felt the music, and shivered in anticipation of the night to come.
