A Futa Family Vacation

"Okay, smart one, let me just explain it scientifically so you'd understand. Humans basically... we evolved to fuck! That's one of the things that first alerts us that someone will be a good mate. You think cavewomen had a girl do an IQ test before making babies with them? No, they just fucked first and then hit em on the head with a rock later if they didn't like their personality or whatever." The blonde's sister said. The blonde actually managed a laugh.

"...You're an idiot." She grinned slightly and shook her head, before Ella and the others caught her attention.

"Hey, girls, I know it's been awhile since you've all been together, but Alex and Chris are excited to hang out with you while we're all here! And this is their friend, Ella. Ella, the cute brown haired girl is Julie, and this is Sierra". Stella happily introduced Ella, giving her a little wink. Ella blushed and shyly waved towards Alex and Chris' cousins, Julie and Sierra waving back.

"Wow, your eyesight must be even worse than Sierra's!" Julie loudly commented. Sierra hit her sister on the shoulder, while Stella just laughed. Alex admittedly found it pretty funny too, while Ella just grinned sheepishly and rubbed her neck.

"God, can you not be rude for once?" The bespectacled Sierra chastised Julie.

"What'd I do?" Julie sincerely asked her taller sister, shrugging.

"I-it's okay, I really am blinder than a bat. Everything looks really blurry without them, even up close." Ella explained, Julie nodded sagely as her facial expression seemed to suggest that she was wondering if Ella's eyes were actually that big without her glasses.

"Alright, you girls help Alex and Chris unpack their things, okay? Ella, would you like me to introduce you to everyone?" Stella said.

"S-sure." Ella smiled nervously and let Stella lead her off to the next room over.

In the next room over, a tall and athletic looking girl was doing jumping jacks, dressed in nothing but a t shirt and tight workout shorts.

"...My goodness, Terra what ever are you doing?" A frail looking girl with black hair asked. She looked rather annoyed as she laid on her bed and attempted to read.

"Sam, I was busy working because my first day off is actually tomorrow, then I had to make sure I packed everything, then we made loads of stops on the way here because YOU kept having to go pee, so I'm doing my daily workouts now!" The fit blonde girl enthusiastically explained. She then switched to kicking and punching the air, at which point Sam nervously moved further back so Terra wouldn't accidentally smack her in the head.

"I have an abnormally small bladder! Plus, who drives for so long, anyway? If we were taking a private jet we could've gotten here much faster." Sam crossed her arms and pouted. Terra responded to this with her typical overdramatic laugh, while the redhead painting on a large canvas behind them giggled softly.

"Sorry, don't think I've saved up enough for that on a college students budget. Maybe next year!" Terra joked.

"Most people aren't fortunate enough to have been born the daughter of the president of a real estate conglomerate." The redhead quietly and politely explained. Sam huffed.

Soon, Stella and Ella came into the room, and Ella blushed as she was instantly met with the sight of Terra's bulge in her shorts. Admittedly, it was fairly modest, as no details could be made out, but that didn't stop the teenagers eyes from widening like mad.

"Everyone, this is Alex and Chris' friend, Ella!" Stella gladly introduced the girl.

"U-uh hey there, everyone." Ella shyly greeted them and waved, averting her eyes from Terra. The blonde athlete smiled and happily shook Ella's hand, before guiding Ella by the shoulder by the shoulder and introducing her to the other girls.

"Hey there, Ella! I'm Terra, the grumpy pampered girl over there is Sam, and the super talented soon-to-be-famous painter over there is River!" The freckled River smiled kindly and waved, slightly blushing at Terra's compliment.

"River is Stella's daughter, but me and Sam aren't, we're just her friends." Terra continued to explain. Stella laughed, as she saw the girls were already hitting it off.

"I see you girls are already getting along! If you need me, I'll be downstairs." Stella said.

"Wait, which rooms will me, Alex, and Chris be staying in?" Ella asked. Stella shrugged.

"Ya'll are adults, you can sort that all out amongst yourselves. Oh, and the next room is just for Robin and Luna. See ya!" Stella smiled wide and then left.

"Why do they get a room to themselves?" Sam asked.

"Why shouldn't they? They're a couple after all, they probably want some alone time so they can...you know." Terra said, and giggled at her implication.

"Isn't Robin like, very Christian though? You'd think she wouldn't want to do it until they got married." River proposed.

"Yeah, but a lot of those girls are secretly freaks. I can't even tell you about how many girls put up a 'pure' act, and then..."

"Sh-should we really be talking about them like this when they could be in the next room over?" Ella asked.

"Hmm. Probably a good call." Terra said, and then shrugged.

...

Later, Chris, Alex, Sierra, and Julia were all getting dressed into their sleeping clothes, Alex in a cute white nightdress, Chris in pajama bottoms and a t-shirt, Julia in panties and a t-shirt, while Sierra simply pulled a blanket over herself and tossed her clothes onto the floor. Alex laughed.

"You still sleep naked?" She asked, amused. Alex could still remember their sleepovers from when they were younger. Sierra nodded.

"It's always made it much easier for me to fall asleep, I don't know why." Sierra shrugged. She would've been embarrassed, but she'd known them since they were kids, so it made things a little less awkward.

"You get used to it, to be honest. Except the nights when she has a wet dream and you can see her tenting the blanket. And it was even worse when she used to be a sleepwalker, good thing she doesn't do that anymore." Julia giggled. Sierra blushed really hard and gulped.

"Sh-she's joking." Sierra said. Julia smiled.

"Right, joking. Anyway, goodnight everyone!" Julia said.

"Wait, where's Ella?" Alex's goth sister asked as she started to tie her hair up into a ponytail.

"Stella told me that Ella and the others got along really well, so she decided to sleep in their room since there isn't enough room in here for her." Alex said.

"Ugh, why couldn't me and Ella switch room..." Chris grumbled as she pulled her blanket over her.

"I think our Moms think forcing us to spend time together during this vacation will make us closer, or something." Alex shrugged. Chris scoffed, and Alex couldn't help but share her cynicism for once.

Soon, the lights in the house went off one by one, as every lady in the house started drifting off to sleep.

Alex tossed and turned in her nightie as vague images and sounds flooded her unconscious mind. Pretty faces, soft hands, kissing sounds, pleasant smells, and the warmth of young bodies rubbing against each other.

The girl groaned, her cute little cock slightly hardening. The fact that she hadn't touched herself in awhile, and her being under the same roof as a bunch of young attractive ladies, both of those combined in her dreams and turned her on, her horny unconscious mind not caring that most of those young ladies were related to her.

Her cock soon slipped out of her panties, rubbing against her thigh and the soft silk of her nightdress. Alex rolled onto her side and rubbed her thighs together.

"Nnng, ahhh~" Alex gasped, her now rock hard erection burned with arousal as it rubbed against her thighs. Her dreams continued to get lewder, soft moans and suckling sounds accompanying the sensory overload going on in her dreams.

Alex's nostrils flared as not only the scent of her arousal began to waft her way, but also something else. A scent came from somewhere else in the room, and simply urged the sleeping girl to continue her lewd actions.

"Ahh, ahh, mmm~" She whimpered. The night went on like this, the girl not waking up once to tend to her needs. Her cock simply throbbed and drooled pre as she began to sweat under the warmth of her blanket.

Then, suddenly Alex eventually awoke, bolting upright. Her breathing was heavy, and her entire body was sweaty and burning like it was on fire.

"Wh-wha?" The tired and puzzled girl whimpered and took off her blanket, revealing her cum covered lap, and her still-hard cock that was pounding and pulsing in her hand.

"Eep!" Alex threw her blanket back over herself, her eyes darted over the rest of the room. No one else was there. Thank god.

Alex opened the curtains to the window just above her head, the soft light of early morning poured through and illuminated the dark room.

The mortified girl began to clean herself up before anyone else could enter the room, she couldn't believe that she'd had a wet dream while other people had been so close to her! She prayed to God that no one had noticed.

Alex groaned as she slowly got up, picking a towel out of the dresser. She stood up and trembled slightly, why was her cock still hard? It wasn't as steely as it had been, but it should've gone down by now! She desperately hoped one of the showers was free so she could properly clean herself and relieve herself of her morning wood.

She soon took off her nightie and wrapped the towel around her body, making sure it properly concealed her slight erection. Once that was sorted, the girl left her room and looked down the hallway to see if anyone was there. It was empty. And quiet.

It was about 8:30 AM, why was it so quiet in such a crowded house when everyone should've been awake? Did everyone go off without waking her up? Typical.

But at least that meant it was less likely that the shower was taken! Alex could jerk off in peace, and she'd have enough time to wash her cummy nightie before everyone came home.

As the girl made her way down the hallway, a strange scent wafted her way, filling her nostrils and making the hair on the back of her neck stand in attention. Her cock twitched.

Alex whimpered, but kept on walking. Something strange was definitely going on, but Alex couldn't quite figure out what it was. And then she started hearing noises.

She gulped and looked down to her crotch to make sure her erection was still fully concealed, before realizing the sounds weren't coming her way, they were coming from the room at the far end of the hallway, whose door was slightly ajar.

"Ahhhh~" Alex's heart practically leaped into her throat. Was that sound what she thought it was? No, it couldn't have been.

"Mmm~ F-fuck~ Yes, make me cum~"

"Oh my god..." Alex felt like she was going to faint. A choir of soft moans echoed out not just from one room, but multiple! It sounded like the voices of several girls she couldn't quite identify. What the hell was going on?

Curiosity got the best of the girl, and she sneakily crept up to the door, peering in through the crack.

"Nnng~ Suck my cock!" A blonde girl with glasses moaned hungrily. Sierra! Alex gasped, thankfully those in the room were too caught up in their passionate lovemaking to hear her. Sierra looked delirious with arousal, her face was flushed bright red and her eyes looked unfocused and glazed.

Tending to the girls' cock was...Alex cracked the door open slightly further, and covered her mouth to hide her reaction to what she saw. It was Ella. She was practically devouring Sierra's hard-as-steel rod, whorishly moaning and whimpering as she suckled the throbbing fuckstick. Someone was slamming into Ella from behind, but it was hard to tell who it was with how dark it was and how Alex didn't have a full view.

The poor girl stepped back from the room, she'd seen more than enough.

"Wh-what the actual fuck..." Her attention was soon brought back to her cock, as it relentlessly throbbed and hardened with a renewed vigor.

"No no no no..." The confused and horny girl trembled, her cock and pussy now aching with the arousal. "Wh-what's happening~" She whined, now running to the bathroom so she could relieve herself. She could hear more moans coming from Robin and Luna's room, but she simply ran past it. It didn't take a rocket scientist to figure out what was going on in there.

Alex soon made it to the bathroom and pounded on the door, still trying to get those horrible (horribly arousing) images out of her head. It just didn't make sense! It was almost like...

"I-I'm in here!" Alex could hear her sister Chris say from the bathroom. She could also hear soft squelching and stroking sounds.

"How long are you going to be in there!?" She questioned her sister.

"A long time! Now fuck off!" Chris said, clearly annoyed as Alex was interrupting her from whatever she was doing in there.

Alex whimpered, but simply went to go look for another bathroom. She seriously hoped the door to the other bathroom wasn't in one of the bedrooms.

As she made it into the livingroom, she noticed that someone must have had turned the tv on earlier. Alex gulped, the curly haired news anchor looked to be in about the same situation she was in. Flushed skin, heavy breathing, and a slightly glazed look in her eyes. Something about seeing such a normally professional woman in this state made her so horny, though it mortified Alex to admit this to herself.

"For those of you who have just woken up and have perhaps not been affected yet, we would like to inform you that, against all odds, the Heat has come much earlier than normal this year. Not since the summer of 1970 has a wave of breeding pheromones come so early.

Needless to say, we have not prepared thoroughly for such an event, and many of the major cities have scrambled to get under control the millions of women who have been consumed with the pheromones that humans normally release from late-July to early-September." Alex's jaw was wide open with shock and horror as the news started to show several scenes (admittedly censored) of mass orgies taking place at supermarkets, offices, just about everywhere where there were adults.

Society normally had time to prepare for when their primitive Futa urge to breed took over, but this was clearly not the case this year. The hormone pills that work to different degrees for different women, the sex toys that women brought to work and school, and the weeks of physical and mental preparation were not present now. Women just went about their day as normal, and were suddenly overcome with the urge to fuck. So they did.

"The more rural areas should be less affected due to the smaller population, but the heavy amount of pheromones in the air in the big cities is currently making it essentially impossible for people to go about their day as normal, as no precautions have been made this early in the year.

We recommend that those in heavily populated areas do not go out into public unless necessary, at least until everything has gotten under control." The attractive redhead news anchor read out, and just by looking at the poor womans' face, Alex could tell that she desperately wanted to touch herself. Or have someone touch her.

Alex couldn't blame the woman, considering that even the heavily censored events that took place on the screen made Alex's cock and cunny ache in need.

'Need to lock myself in my room before I end up doing it with anyone here...' The girl panted, desperately running back to her room to relieve herself. She didn't at all want to look for the other bathroom and risk running into another desperately horny girl, it was safer to just backtrack to her room.

As soon as she made it into the guest room, Alex locked the door and instantly threw off her towel like it was attacking her, and started to methodically stroke her burning, almost painfully erect cock.

She trembled, a low moan escaping her soft lips. "Ahh, uhmm, nnggh~" Alex closed her eyes and almost doubled over in pleasure once she plugged her clenching cunt with three fingers from her free hand.

"Ahhhh~" Her strokes increased in speed and intensity with every stroke, her fingers also keeping up the pace in her molten hot pussy.

"Sh-shit, shit, shiiiiit~ Why did this have to happen noooow~" Alex groaned. What bad luck that her first time experiencing the Heat had to happen like this. With no preparation, in a house full of relatives who were just as out of control as she was.

Alex continued to pound her cock, finding it nearly impossible to divert her thoughts to fantasies not involving her friends and cousins, whom she'd never thought of sexually at all.

Alex thought of girls she'd had crushes on at school, porn stars, celebrities, literally anything to distract her from thinking about her best friend sucking her cousins cock. So hungry and ravenous. Like she needed cock.

"Unnnggh~ No no no nooo~ D-don't think about it~" But she couldn't not! Thoughts of Ella and Sierra taking turns slipping her cock into their soft, wet mouths filled her mind. And they were getting pounded from behind like Ella had been. Julie was slamming into Sierra's cunt, making her moan whorishly. And Ella's face contorted in pleasure as she was being filled by... Chris.

"Fuck! Ahhhhh~" Alex whimpered almost pathetically as her first orgasm of the day rippled through her, and her painfully hard cock blasted a hot, fat load onto the door.

She continued to shamefully pump her erection, whimpering and gasping girlishly as she trembled in feverish pleasure.

"Mmmm, hmmmm, nnngh~" She thrusted into her petite hand and shot another load at the wall, mewling as her eyes struggled to maintain focus.

"G-god, this sucks so baaaaad~" What was supposed to be a fun and relaxing vacation had turned into this humiliating and nerve wracking experience, and she still couldn't help but wonder what her family members were doing right now. Just thinking about how her parents were in a similar situation right then almost made her sick.

If only they'd had time to prepare, they wouldn't be in this situation now! Then again, if they had time to prepare they wouldn't have gone on vacation at all.

But there was one question Alex did have. Even as someone who hadn't experienced the Heat before, she knew it shouldn't have been this intense, even without the weeks of preparation beforehand.

She thought she could recall in biology class that she'd read that the initial spread of the Heat every year was always the most intense, and the arousal usually died down to various degrees depending on the individual, but she honestly couldn't remember because of how hard it was to think at that moment.

Alex continued to pleasure her desperate and sensitive little cock as time ticked by, nearly an hour passed and Alex was still playing with herself, why the hell was she still so horny!?

The poor girl panted in arousal and exhaustion as she started to slap and pinch her cock and nipples, she had basically resorted to doing anything to reach a climax that would calm down her arousal, but every body shaking orgasm simply brought a new wave of renewed arousal!

"Nnnng~ Stoooop~" Alex whined to her needy cock, as if that would help with anything. It didn't. Her toes curled as another orgasm ripples through her body, a long shot of cum staining her flat chest and lips. Alex mewled and licked her lips, still furiously pumping her cock. She then heard a knock on her door.

"Wh-what is it!?" Alex asked.

"J-just seeing if you're okay." It was Chris' voice. Chris was asking if she was okay? That was out of character.

"Uh-ummmm~ I uh...it's a bit complicated." Alex told her sister, which was a pretty big understatement of the situation.

"...Look, Alex. ...I know you're horny. W-we all are. I-I've been able to distance myself from the o-others but...I can't stop. I-it won't go away. I need your help, and I think you need mine too." Chris said. Alex's cunny clenched harder around her fingers as her sisters breathy and aroused pleas made her tremble in arousal and uncertainty.
