S.I.N.

“In the wake of what many considered a worldwide pandemic, a new virus has emerged at the forefront of everyone’s minds. This virus has no treatment currently and is reportedly spreading in certain locations, affecting as many as sixty percent of the female population.”

“Turn that off, we don’t need to listen to propaganda like that.” Dina’s father said.

Dina looked from the television to her father and then towards her mom. “You think that’s not true daddy?” The girl asked.

“I know it isn’t. Don’t worry about some stupid virus like that. It’s mass delusion. Something like that can’t happen.”

As her mother turned off the television, the three family members went back to eating breakfast. Dina had her doubts about what her father said. She’d gotten a call over the weekend from Sue at school. She said her older sister had been caught in class upstate where she attended college. She was caught performing oral sex on a guy, someone Sue said her sister had never even met before being caught that day.

Her father was a strictly old-fashioned guy, as was her mother. Neither of them would ever believe in something as strange as the S.I.N. virus. Sue swore it was true, that her sister was taken into a local center where research was being conducted. Apparently the research wasn’t providing any answers, other than revealing the symptoms and direct effects of catching the virus.

Dina looked down into her cereal bowl. Just the thought of such a virus made her simultaneously terrified and fascinated. There was only so much she could do to control the teenage hormones she had. It was easy to imagine what that virus must be doing to people. Her friend Todd had called last night. Of course he’d told her mom he was calling to check on some homework notes. What he really called to say was that apparently one of the teachers in the freshman classes was caught on Friday having sex with several of her students. He didn’t know too much more but he wanted to warn Dina. The virus was in their school.

She wasn’t sure whether she really believed him or what her father said just now. Either way, Dina wasn’t feeling much like eating. Her stomach was nervous just thinking about school.

“Okay Dina, you’d better head on or you might be late.” Her dad said.

Reluctantly the girl stood, looked sheepishly over at both parents and mumbled a quick goodbye. Her mind was clearly still focused on what Sue and Todd had told her. Was this really worse than the Swine Flu scare? Maybe it was no different. Everyone panicked over how many people Swine Flu would get and really it turned out to be nowhere near as serious. Maybe S.I.N. was the same way. Maybe nobody was actually catching as severe a case as she’d been told about. It seemed reasonable to think it might be merely the power of suggestion. Dina had done science experiments involving one group getting the sugar pill equivalent to what another group got. Sometimes the power of suggestion was enough to convince someone they were getting something they really weren’t.

On the drive to school, Dina kept her mind focused on that thought. This was all just a mass panic. Her dad could easily be right not to worry about it. Just the symptoms of the S.I.N. virus sounded made up. The name itself was hardly any better.

S.I.N. Dina thought, could they have come up with a better acronym? She’d had to do research online to learn anything. Every time she tried to watch the news over the weekend, one of her parents had flipped it off, lecturing the girl about not believing everything she saw on TV.

It stood for Sudden Induced Nymphomania, and if that wasn’t simple enough, the explanation of symptoms was even crazier. Apparently the virus only affected women over the age of sixteen. It created an overwhelming desire to have sex in any form. Supposedly the symptoms were a preoccupation with sexual thoughts and fantasies, the uncontrollable urge to touch one’s self, thoughts of others touching one’s self, aggressive behavior in regard to sex, and ultimately complete failing of all moral and ethical behavior concerning anything sexually explicit.

Dina turned onto a new street, keeping an eye out for anyone walking towards the school. She couldn’t believe what the news was saying. This virus could make you a slut. It sounded completely insane, but she’d seen it at CNN online. The virus supposedly had mutated from some form of a treatment primates were given in zoos. They needed to increase the mating behavior in mature animals, so they developed a treatment that stimulated the females. Somehow, it was believed the virus called S.I.N. resulted from some unknown mutation that allowed the treatment to become airborne and metabolize in the human immune system.

Walking along the side of the street, Dina saw several of the senior cheerleaders. She slowed down and waved. These were usually the friendliest girls in school. Everyone liked them. Something seemed different today. None of them even looked her way. As Dina came to a stoplight, she turned and watched the girls walking down the sidewalk.

Becky was giggling in some close conversation with Simone and Janet. The three girls were wearing their cheerleading outfits and playing with their hair. None of that was so strange, Dina thought. But when two businessmen walked out of a nearby store, the cheerleaders behaved very strangely.

Dina almost thought she was imagining things, but all three of the high school girls stopped talking and giggling simultaneously. They licked their lips and practically skipped up to the two men. She couldn’t hear what was said, but Dina saw the two men stop and look down into the girls’ faces. Their eyes widened at whatever Becky was saying and one of the men began smiling and nodding his head.

The light changed and several cars began blowing their horns as Dina slowly started out, still craning her neck to look back to the cheerleaders. Becky was leading one man and Simone and Janet had their arms around the other. They were walking into a thin alley between buildings. Just before Dina lost sight of them, she clearly saw the man’s hand all over Becky’s ass.

“What the fuck?” Dina said out loud.

Was this really happening? Had Becky and the other cheerleaders been infected? She’d known them since junior high. She’d often thought of joining the squad. They begged her all the time, saying she had the looks and would definitely look great in the outfit. Dina hadn’t joined but appreciated the compliments. They were cheerleaders, but these were good girls. They were sweet and wholesome, always going out of their way to help people. Had they become sluts now? What were they doing in that alley with those two men?

Her mind was almost running away with her when Dina saw Sue walking along the road up ahead. She whipped up beside her and slowed the car down. Rolling down her window, Dina called out to her friend.

“Hey, Sue, come on. I’ll give you a ride the rest of the way.”

As soon as Sue was in the car, Dina started back down the road. She glanced over at her friend. Something seemed to be on her mind as she’d hardly said a thing.

“Are you okay?”

“Fine, really good, how about you?” Sue answered, staring out the side window.

“I think I’m okay, but have you seen Becky or the other cheerleaders lately?”

Sue looked from the window over at Dina. As she did, the girl smiled and let her eyes flow up over her friend’s chest. “Yeah, I had them over last night. We had lots of fun.”

Suddenly Dina noticed just how strange her friend was acting. Her voice seemed incredibly relaxed and even her manner of dress seemed a little odd. Dina found herself trying to ignore just how much cleavage her blonde friend was showing.

“Are you sure you’re okay? I mean, I just passed Becky and the others. They looked... well they looked different.”

“Fine, fine, we’re all good. You should really lighten up. Loosen your collar a bit, have some fun.”

Dina pulled into the school parking lot and tried to ignore her friend’s very odd attitude. “What about your sister, have you heard anything more?”

Sue looked blankly over at her friend. She appeared to have very little thought going on inside her head but she giggled a little and leaned over towards Dina as she parked the car.

“My sister, oh yeah. She’s fine too, thanks so much for the ride.”

Dina was completely caught off guard as her friend leaned in and planted a wet kiss right on her cheeks. She was even more shocked as she felt Sue’s hands tweak her nipple through her top. Pushing the girl off, Dina pulled away towards the driver’s side door.

“What the hell? What’d you do that for?”

Sue giggled. “Just thanking you properly. We really should spend some more time together. Boys are totally fun but us girls should stick together sometimes.”

The blonde girl giggled some more, opened the passenger door, and skipped off towards the school. Dina leaned against her window in complete shock. Did Sue have the S.I.N. virus too? Could she have gotten it from her sister, or the cheerleaders? Oh my god, Dina thought, wiping at her cheek. Did she just give it to her?

The halls were hectic when Dina entered. That much never changed. What did change was some of the activity she saw when she really stopped to pay attention. Several girls from a lower grade level were gathered by the ladies room. That wasn’t at all unusual. What they were doing was pretty odd, to say the least.

Dina stood by her locker, trying to act casual. She watched as one and then each of the other girls reached beneath the little skirts they wore and pulled down their panties. The group of students all looked around, grinned, and then began stuffing their discarded panties into a nearby trash bin. After that, they simply skipped off happily to class.

As if that wasn’t strange enough, Dina nearly choked when she turned around to see Becky up against the lockers. She’d opened her locker on one side of her so it blocked what she was doing in that direction. But from where Dina stood, she could see it all. Adam, one of the senior football players, was manhandling Becky’s tits. He’d pulled her top up and released her jiggling little breasts. As Dina watched, he sucked on the girl’s nipples and thrust his hand up in between the large fleshy orbs, making a fucking motion.

Dina stared so blatantly, both students looked over and saw her watching. Becky simply smiled and leaned her head back, letting Adam mock fuck her tits with even more depraved crudeness. “You wanna have some fun next Dina?” Becky asked. The girl giggled and Dina instantly turned red, walking away towards class.

Through her entire first period class, Dina kept picturing what she’d seen. Girls throwing away their panties, a friend of hers letting a guy play with her tits, even her own best friend kissing her and squeezing her breast. This was all too much. Whether it was mass panic or a real epidemic, the S.I.N. virus seemed to be here in this school.

She looked around at others in class. Most of them seemed just fine, perfectly normal. A few girls towards the back of class looked a little different though. Dina knew these girls. They were the ones who dressed in black all the time, they rarely had much use for school or learning. However, today these girls were staring attentively up towards the front of the classroom. Turning to see where they were looking, Dina felt her breath catch in her throat. The girls were staring right at Mr. Harris. The English teacher was currently writing something on the board. Those girls were staring at him like a piece of meat. And what a delectable piece of meat he was, Dina thought, licking her lips.

Her eyes widened and Dina slapped a hand up to her mouth. Had she just thought that? Had she just found herself looking at Mr. Harris’ ass and thinking something as outside her character as that? She shook her head and looked down at her desk, trying to focus on anything but the sensations she’d felt upon licking her lips.

By the end of class, Dina had convinced herself she was fine. It must’ve been some fluke that she found herself so interested in the teacher like that. The power of suggestion, she thought.

At her locker between classes, she again looked around to all the strange activity going on. A different group of girls were standing at the entrance to the ladies room. These were juniors, she thought, and they seemed to be more focused on their tops than what was beneath their skirts. Dina slowly put her books away, watching the girls each open their tops up completely. Anyone in the passing hall could see the teens as they hauled their tits out from their bras and threw the offending undergarment in the same trash bin that no doubt now contained a decent amount of panties. Surprisingly, Dina didn’t find herself so shocked at seeing girls baring their tits in a public hallway. She actually found herself thinking how much nicer hers were than some of these girls.

A noise behind her drew her attention and Dina closed her locker, looking down the hall from her. Becky had made the noise and she had good reason to. The cheerleader was now facing her locker, the open door still managing to hide some of what she did. It couldn’t disguise enough though. A small audience had formed in the passing kids and amazingly no one seemed overly interested in doing anything about it.

“Ohhh...” Becky moaned into her locker.

She was hunched over just slightly like she was reaching for a book. But Adam, the football player from before was now thrusting slowly into the girl from behind. He’d simply walked up, freed his cock, and plunged right up inside the girl’s wet cunt. Becky gripped the edges of her locker and allowed the boy to fuck her. She looked over at Dina and smiled, moaning with every sharp insertion of Adam’s cock.

Dina couldn’t believe what she was seeing. Becky was a good girl. They went to the same church and she knew this was not how Becky acted. The most surprising thing that scared Dina more than she’d thought it would, was her own reaction. She wasn’t trying to stop it, she wasn’t saying anything in protest of the behavior. She wasn’t even looking away.

Just like many of those passing by, Dina simply watched as Adam bucked his hips harder and faster, grunting with every forward movement. He reached his climax quick and dirty, thrusting deep into the girl from behind. As Adam leaned in, kissed Becky, and then took off down the hall, Dina found her eyes drifting down. She was fascinated by all the cum streaming down Becky’s legs. It was disgusting and yet she couldn’t look away.

During her next class, Dina saw Todd. It was the first time they’d seen each other since he called her, telling her about the freshman teacher. She smiled when he sat down next to her and for some reason she felt annoyingly bubbly in his presence. She almost caught herself giggling as he leaned in close to whisper something to her.

“Have you seen what’s going around campus today?”

“You mean the girls?” Dina asked, barely keeping from leaning in closer and just licking the boy’s face.

“Yes,” Todd said, looking up to the front of class. “Half the girls in school are acting like hookers or something. They hang around by the men’s room and whenever any boy tries to enter, they have to fight off the advances.”

“Yeah?” Dina asked.

Todd looked her way. “Some of the guys aren’t refusing. I have to admit it isn’t easy. These girls are really desperate for it.”

As the class got started, Dina lowered her voice. “It? What do you mean it?”

Todd leaned even closer and whispered a single word. “Sex.”

Dina nearly fell over as the sensations welled up inside her. She felt her pussy go wet as soon as Todd said the word sex. Immediately the images that came to mind were of Todd fucking her. She saw herself being his little cum slave. She’d do whatever he wanted as long as she got a taste of his hard cock in any hole he wanted to put it in.

“No.” Dina practically shouted, straightening up in her chair and suddenly feeling very embarrassed as the entire class looked her way.

Mrs. Williams, the history teacher, stood impatiently at the front of the class. “Is there a problem, Dina?”

She shrank back into her desk, trying to get a hold of herself. “No... no ma’am. Sorry.”

As class continued, Todd looked over and simply mouthed asking if she was okay. Dina nodded and quickly looked away from the boy. Even his chiseled features just being in her field of view were too much. She couldn’t focus when she looked him in the eyes.

This was more than just power of suggestion, Dina thought. It wasn’t mass panic either, this was something real. It had to be. Whether S.I.N. virus was real or not, the symptoms were definitely there. By the end of class, Dina was having difficulty thinking of anything other than sex. She caught her hands slipping down under her desk. She had to clench her fists together just to keep from sliding several fingers beneath her dress and finding her warm wet slit.

“Get control of yourself, come on get control.” Dina said, staring into her locker between classes. She looked over at the ladies room. Nobody was there this time. Maybe things were getting better she thought. Dina grabbed her book bag and headed into the restrooms. Unfortunately, although nobody was outside, the inside stalls were fully occupied. She heard moaning in every stall and many seemed to have more than one occupant.

Dina hurriedly wet her hands and looked at her face in the mirror. This had to be some kind of nightmare, she thought. Looking into the reflection behind her, the girl saw a stall door open. Out came Sue. Even worse was that Sue wasn’t alone.

“Shit babe, you were great.” Aaron said.

Aaron was another one of the football players, only he was one Dina knew and trusted. He was ordinarily a stand-up guy, a real gentleman. Watching the guy slap Sue on the ass and leave the ladies room, Dina wondered if somehow the virus did affect guys.

“Hey girlfriend.” Sue said. She walked on slightly unsteady legs over to the sink beside Dina.

“Sue?” Dina said. She still wasn’t sure what was really happening.

“Man, that boy has one big cock hidden in his pants. He really filled me up. I swear it feels like my belly’s at least two inches bigger than this morning.” Sue laughed and rinsed off her hands, grabbing a paper towel and wiping the sweat off her forehead. “Of course I can’t forget the other three guys who fucked me earlier. Those men did their best to fill me up too. Isn’t it fun Dina?”

Dina was staring at her friend like she’d never seen her before. It took her a second to even catch up in the conversation. “UmÉ isn’t what fun?”

Sue playfully slapped at Dina’s shoulder. “Silly, being a slut of course. Sluts have lots of fun. And I can’t wait to get home later. My step daddy is such a hunk. I think I might put the moves on him later tonight. Can’t you just imagine that man pumping away between your legs.”

Dina gasped but said nothing more as Sue turned and walked out the door. She looked back at herself in the mirror, trying to ignore the moaning coming from most of the stall doors. She’d known Sue a long time, longer than her stepdad had even been in her family. Never before had the girl expressed one bit of interest in the man. Now Dina was fighting off her own fantasies, ones in which not only Todd plowed her tight little cunt, but ones where Aaron, Adam, and even Sue’s stepfather joined in to fill all her holes. She imagined them shooting cum inside her, on her, in her face. She imagined them roughly groping away at her tits, lifting them up and letting them slap back against her belly as they licked and drooled all over her hard teenage nipples. Dina nearly collapsed to the sink as a minor orgasm washed over her. Something was wrong with her, this clearly wasn’t right.

Rushing from the bathroom, Dina nearly ran right over Becky. The girl was now not trying to hide anything. She was on all fours in the middle of the hall. One of the band geeks was behind her. He had his hands on her hips and was thrusting a very hard cock eagerly into the girl’s sodden cunt. Dried cum speckled the girl’s face and back. Several sticky streams of the stuff made a nice puddle in the hall floor.

This was crazy, Dina thought. Where were the teachers? Why weren’t they doing anything about this? She had to find out what the deal was. Painfully averting her eyes from the public fucking and the line of guys waiting their turns, Dina ran off down the hall towards the school office.

Standing outside the office, Dina heard the now familiar moans she’d heard in the restroom. No, she thought, not here also.

Opening the door, Dina peeked in and saw a sight she couldn’t ignore. She’d heard people say there were things you couldn’t unsee. Until now, she’d never actually seen one of those sights.

The office had a large carpeted space between several desks and the doors to a few rooms. In the center of that carpeted spot was a group of female students and teachers. Dina saw Janet and Simone, as well as several junior and even sophomore girls. What they were currently doing was terrifying in just how arousing it was. Simone was completely nude as was the female teacher she made out with. They were on the floor groping away at each other while Janet lay back and allowed one of the Junior science teachers to suck on her clit. A few other girls were laying mouth to pussy, creating a chain of depraved orgy-like activities that filled the room.

Dina stood by the door and smelled the heavenly scent of sex that permeated the room. It was so strong, she almost failed to even notice what the men were doing. Several male teachers and even the principal were currently jacking their cocks in a ring around the women and girls. They were aiming them at whatever parts of the girls they could, standing there like gunmen ready to spray the orgy with bullets.

What came from their cocks wasn’t bullets, but it looked just as hot. Dina gasped and failed to even realize she had her dress pulled up and a hand buried down the front of her panties. The men were spraying rope after rope of cum all over the teachers and students. Simone looked as though she’d been basted in the stuff, her young body dripping all over the woman she made out with.

As the men turned to see her standing there, Dina backed out of the room. She tore off down the hall towards her locker. She had to catch her breath. Trying to ignore the sight of Becky and now Sue on the floor in the hall, Dina shoved her face in her locker and took a deep breath. It was the only place that didn’t smell like sex, dirty hot sex. She breathed deeply and tried to calm herself. This was important.

Suddenly she felt someone step up behind her. Hands roamed over her young hips and she nearly melted into the locker. Looking back over her shoulder, Dina saw Todd standing there with a grin on his face. He had his hands up under her dress and was pulling at her panties.

“Todd?”

“Hey Dina, you know I’ve always thought you had a cute figure. I think I’d like to get intimately acquainted with it.”

He didn’t sound like himself. Something was definitely wrong. This wasn’t how things were supposed to be. “What are... you... doing?” Dina gasped.

She bent over even further, grabbing the edges of her locker as Todd pulled her wet panties down her legs. She stepped out of them without even thinking. Why was she doing this?

“You want this don’t you Dina?” Todd asked. “You want to be a slut like all the other girls don’t you?”

Dina shuddered as Todd slid his fingers up into her wet cunt, rubbing inside her and leaning over her ass to whisper into her ear. She did want this, for some reason, she simply couldn’t imagine not having him turn her into a slut. S.I.N. virus or no virus, she was nothing but a little slut. She’d spent so much time studying, she never even focused on what was really important. Getting fucked was not only fun, it was easy to accomplish. What man didn’t want to fuck a hot high school girl like her?

She thought back to Becky and the cheerleaders and those men they’d pulled into the alley earlier. They were fucking those men. They had to be. What else would be the reason for pulling two hunky guys like that into a dark alley?

Todd was now moving in closer behind Dina. He lifted her dress and she could feel he wasn’t wearing any pants or underwear. She wanted this. It made sense. Why fight it any longer? The girl gasped as she felt his smooth hard cock press into her moist slit. She leaned over further and thrust back at the boy.

“Oh Yesss!” Dina moaned. She felt him slide further and further inside her. His cock reached a slight barrier and she braced herself hard against the locker. “Go ahead,” Dina said. “Go ahead and fuck my virgin cunt.”

Todd grunted and slammed his hips forward, driving balls deep inside the young girl. He began fucking her with a frantic and steady pace, slapping his hips into her ass and reaching around her to grab at her tits.

Dina groaned and flailed her arms around as her belly sucked that delicious cock up inside her. She felt her muscles twitch in orgasm and wiggled from side to side as he screwed her deeper and deeper. The hallway was filled with girls being bent over and mounted, guys grunting and sending load after load of cum deep inside these student’s bodies. Dina looked over at Sue on the ground. She was taking two cocks at once. She felt jealous. More than anything right now, Dina wanted more cocks inside her. She wanted the whole school to fuck her. All she wanted was to feel as slutty as possible. Being slutty was so fun.

“Oh yess... Oh... Oh please fill me up.” Dina moaned. She’d heard the cries earlier. Now she understood them. She needed her wet little cunt all filled and bloated with seed. She wanted guys fucking as much inside her as they could.

Todd grunted even louder and sank his cock all the way inside Dina, reaching depths past her cervix. He flooded her body with cum, spraying as much inside her as he could before finally pulling out to coat her ass and legs.

Dina leaned against her locker on weak legs. She held herself up but just barely. Looking down, she saw semen pooling at her ankles. This was so good, she thought. Why had she tried to avoid this? Pulling herself up and trying to remain steady, the girl turned and looked Todd in the eyes.

“Thanks for the fuck. I really needed that.” She said. Pulling Todd to her, she kissed him forcefully, shoving her tongue deep inside his mouth and reaching around to grab his ass.

“If you don’t slow down, I might just need to fuck you some more.” Todd said.

Dina grinned and felt the cum leaking from her cunt. “Mmmm... you promise me that?”

Todd simply nodded. Dina looked around at all the chaos unfolding in the halls. Nobody, it now seemed, wasn’t either fucking or being fucked. Everywhere she looked, cocks were filling young cunts. Girls were bent over, on their backs, on all fours, or just flat up against the wall. The school had taken a break from teaching and learning today. Fucking was the only lesson underway right now.

“Let’s skip the rest of classes today.” Dina said, pulling Todd with her as she shut her locker.

“Where do you wanna go?” Todd asked, loyally following the girl he’d just filled with sperm.

“My house,” Dina said. “I wanna spend all day getting fucked by that gorgeous cock of yours.”

As they walked off, Dina suddenly remembered something. She turned and walked away towards the ladies room. Once there, she turned and smiled at Todd, showing just how much of a slutty teen she now was. Grabbing her shirt, she pulled it over her head and threw it in the trash bin. She removed her bra and tossed it in alongside it. The now topless girl walked over and joined Todd as they made their way out to the parking lot.

Outside, all across the lot, teenagers were bent over hoods of cars being fucked. Several teachers were the ones doing the fucking and over in the faculty parking some female teachers were getting screwed by their students.

As Dina and Todd drove back to her house, the girl had a hard time keeping from jumping in front of the wheel and planting herself on top of her friend’s already throbbing dick. She settled for lightly bobbing her head up and down in his lap as they tore down the road.

Dina was all over Todd as they walked in the front door of her home. The television was on in the kitchen again and Dina halfway listened to the announcements as the news broadcaster spoke.

“New information is indicating S.I.N. does appear to be transferring to the male population now. The CDC has stepped in to try and quarantine segments of the population more prone to this virus. This is a very disturbing development as we are getting numerous reports from all over the state that S.I.N. has been identified in most towns today. The reports are alarming and rather graphic.”

Dina was jacking on Todd’s cock as they entered the kitchen and suddenly saw her parents. Her father was currently fucking her mother over the kitchen table. Todd simply looked up and grinned, showing little embarrassment at being caught with his pants down and their daughter’s hand wrapping itself tightly around his member.

“Errr... Hi, sorry to bother you guys.”

“Unghh... No bother.” Dina’s dad said. He fucked into his wife even harder, knocking a glass over. “What are you kids doing home?”

Dina grinned and wiggled from side to side, making sure her daddy saw how big her titties were. She leaned in next to Todd and said. “I figured we’d go to my room and fuck for the rest of the day.”

Her dad stared right into her cleavage and seemed to pick up his pace. “You were huh?”

“Yep.” Dina said. She resumed jacking Todd off and they started down the hall.

“You mind if I join you kids later?” Her father asked. Dina gasped with renewed desire. Just the thought of what those words meant was almost too much to bear. The fantasy of having two cocks at once was too enticing for the girl to care who one of those cocks belonged to.

“Oh yeah daddy, come in anytime. And I do mean cum!”

As the kids ran off upstairs and the parents continued fucking over the table, the news anchor continued on TV.

“Our recommendation right now is that people stay in their homes, avoid all possible contact with anyone suspected of being infected. Just stay inside.”

That wouldn’t be a problem for Dina or her folks, not now that there was plenty of cock and pussy to go around. S.I.N. turned out to be the real deal. Unlike Swine flu though, it actually turned out to be pretty fun.

The End
