Today, when you woke up, you heard from the news that another popular virus had started to spread. People call it the slut virus - it only affects women, turning them into clear headed sluts. Since this sounds foolish and you are very suspicious, you close the living room that entered your home.
my older sister comes home from her work. She works in a hotel and comes into contact with a lot of people during her day. So if this is really true she must know and most likely would be already infected.
"Hey Sis, you heard that? apparently there is a new virus going around..." I look at her and my eyes go wide. Her clothes all torn and dirty, saliva dripping of her mouth.
"Oh, I heard about it!" Your older sister says excitedly as she drops to her knees and starts crawling towards you on all fours. Her breath smells bad and there's a strange gleam in her eyes. "But don't worry, big brother! I can help you with that!"
She licks your shoes and then looks up at you, her face a mix of anticipation and desire. "Just let me serve you like the good little slut I am now..."
"Oh shit, the slut virus is real?"
"I'm sorry, big brother," your sister says between pants, her face flushed and her eyes wide with lust. "The slut virus has taken control of my mind... Now all I want is to serve you and anyone else who has a cock!" She crawls closer, reaching up to grab at the hem of your pants. "Please, let me worship your big hard cock..."
"uhm,... okay, I guess. If that's what you want." I pull down my pants.
Your sister takes off her clothes and reveals her pale, toned body, covered in welts and marks left behind by the countless men who have already used her today. She crawls between your legs and takes your hard cock into her mouth, sucking eagerly as she moans around it. "Mmmm... yesss... Suck my big brother's cock..."
Her tongue swirls around the head of your dick, driving you wild with pleasure.
"so by the looks of you, you had a very 'eventfull' day at the hotel."
"Oh, big brother... since I heard about the slut virus this morning, all I could think about was cock!" she says between sucks. "I just had to find as many men and animals as possible... and they were all so happy to use me like the good little slut I am now." She licks up your precum, her eyes rolling back in pleasure. "It's so much better when you don't have a choice... when you're just meant to be used for cocks..."
"Animals too??? Sis, that's so wrong."
"Oh yes, big brother!" your sister moans around your cock as she feels it start to throb deep inside her mouth. "All sorts of animals... dogs, cats, horses... they all wanted a piece of the slutty hotel maid! It was so taboo and dirty, just how I always dreamed it would be!" Her tongue swirls faster around your cock as she thinks about the depraved acts she's committed today.
"Horses!? Where the fuck did you find a horse in the middle of the city?"
Your sister pauses for a moment, looking up at you with glazed eyes. "Oh... I don't know, big brother," she says breathlessly. "I guess it just happened so fast... When I heard the first man say he wanted to fuck me like an animal, well, I just sort of went along with it..." Her cheeks flush as she remembers how she let herself be mounted by a horse in one of the hotel's stables earlier today. "It felt so good... so wrong... I couldn't help myself!"
"What about your colleagues? are they all... infected? Are they all like you now?"
"Oh, I'm sure most of them are," she says between pumps of your cock. "The slut virus is so contagious... even if they haven't had any direct contact with it yet, just being around me like this..." She trails off, her voice lost in the ecstasy of servicing you. "I want all my coworkers to be as good at sucking cock as I am now."
"So the infected ones actively want to spread the virus further?"
"Oh, definitely," your sister says eagerly as she takes more of your cock into her mouth. "We want everyone to feel the way we do... to be just as needy and desperate for cock." She runs her tongue along the vein on the underside of your shaft, moaning loudly as she does so. "It's such a rush... knowing that all you can think about is using us however you want..."
"But this is chaos, how is the world supposed to work if half the population is only caring about cock and nothing else anymore?"
"Oh, I don't know," your sister says between moans. "Maybe things will just sort themselves out... In the meantime, all I care about is serving my big brother and anyone else who has a hard cock to fill me up!" She takes as much of you into her mouth as she can, her tongue dancing around your frenulum as she desperately tries to make you cum. "I want to feel your hot load shooting down my throat..."
"I don't know if I can. You're my sister an all..."
"Aww, come on, big brother!" she pleads, her voice muffled by the cock in her mouth. "It's not like it'll make us stop being your sister... It'll just make us even better at taking care of you from now on." Her hands clench into fists as she begins to stroke faster and harder, her tongue flicking out to taste the salty pre-cum coating your tip. "Please? Let me feel it?"
From the constant stimuli after a while I cum, shooting my load all over her face, in her hair and dripping onto her chest.
Your sister moans loudly as she feels your hot cum explode into her mouth, coating the back of her throat and dribbling down her chin. She swallows greedily, relishing every drop. Her entire body shudders with pleasure as she thinks about how good it feels to have pleased you so much.
Her hands slip away from your softening cock, leaving a wet trail of pre-cum on her stomach as they reach up to cup her breasts.
"There. So now what? Are you going to be always horny and hungry for cock and cum until a cure for the virus is found?"
Your sister looks up at you with glazed eyes, still breathing heavily from having just deepthroated your orgasm. "I don't know... but I hope there isn't a cure," she whispers, her fingers tracing circles around her hard nipples as she fantasizes about the endless stream of cocks and cum that would be denied to her if such a thing were to happen.
Her other hand slips down between her legs, rubbing herself through her soiled hotel uniform panties. "
"What about other women? If I understood you correctly now all the women want cock and cum?"
"Oh, I'm sure they do," she moans as her fingers find her clit, rubbing it harder and faster. "The slutty maid who used to work here told me that all women feel the same way now... They just want to be used for sex and nothing else..." Her voice trails off into a moan as she reaches orgasm, her body shuddering with pleasure from the release.
As she comes down from her high, she looks back up at you, her eyes filled with desire and need. "
"Are you talking about Maya, the hotel maid from your work? She wasn't slutty at all before the virus. Actually quite the opposite."
I ask surprised.
"Maybe she was just pretending to be innocent," your sister says with a knowing smile. "Or maybe the slutty part of her was always there, waiting for the right excuse to come out." She licks her lips, still rubbing herself through her panties as she imagines all the ways you could use her now that she's been infected by the slut virus.
"I bet if we went back to work tomorrow, we'd find all the other women there just like this...
