Offline/Make Brayden share clothes with his sister
"Brayden, give her your shorts."
"What? Why? I didn't mean to push her!"
"Just do it."
It's like they don't even get what the big deal is. Brayden grumbles his dissatisfaction but does as you ask. Beth sticks out her tongue in retaliation before she even steps into her new shorts, caring far more about her brother losing something than her gaining it. Them being so similar in size is fortunate here as her brother's shorts fit Beth remarkably well, although anything would be better than literally nothing. You sure feel a lot better returning to camp with Brayden in his underwear than Beth bottomless.
You stash Beth's prickle pants in a bush as an extra precaution and assure her you'll come back later to grab them; probably unnecessary, but you'd hate to have Beth try to explain to someone why she's holding onto her shorts and then go into precisely how you helped her.
Assuring the siblings that the clothing reallocation is temporary and that you're all going back to your cabin to change, the moment you stroll into camp they are both too enticed by a high-stakes soccer game - kids vs Uncles - to go through with your plan. They run straight out as they are onto the small rocky pitch, positioned on the flattest bit of land that Uncle Dave cleared between the camp and the river, just past one of the cabins. Only then does it dawn on you that the clearing around your tiny cabin could have been a sports field of some kind. In fact your "cabin" might have been an equipment shed. But now that field is filled with tall grass and flowers and dotted with saplings and hardly suitable for any kind of game with a ball, though it'd be fine for running around.
The kids lose to the uncles in the end, even with Uncle Mike holding his beer, and even after you and Nicky and Lizzy all sub in for the littlest kids. But no one really cares that Brayden is running around in his underwear and no one notices Beth is wearing her brother's shorts. Teaming up with your cousins helps you feel normal again too, so it all works out okay, though it would have been nice to win the match.
Playing soccer in full sun only makes you more tired, even after getting rehydrated, but getting food in your belly is what really perks you up. After dinner, Nicole takes charge of the younger kids as the sun goes down, leading the herd of cats through some silly little games that your bunkmates insist you join in on. No big campfire tonight as the adults seem scattered, but there's still one started in one of the smaller firepits to facilitate evening boozing and young scampering. Once the sun is all the way down and your thoughts similarly darken, you have the funny thought that you could sneak into the bush and jerk off behind a tree under cover of night without anyone knowing, but it still seems a bit risky and desperate, and you'd hate to have to nurse a bug bite on your schlong, so you again resolve to take care of those urges tomorrow.
Beth asks you to take them to bed once she's good and tired, a much better result than last night. When you all get to your cabin you open the door to a somewhat stuffy room, the small box still holding the heat of the day. You manage to prop open one of the windows as much as it will go but feel weird about leaving the door open at night, so you only get minimal airflow into the confined space.
Propping your flashlight up in the corner like a tiny floor lamp, you all get changed for bed. Beth strips off her shirt with a big yawn then returns Brayden's shorts back to him, effortlessly taking off all of her clothes as if she were the only one in the room. You suppose she's treating it just like it's her bedroom, but you have a harder time looking at it in the same way as you timidly open your pants and inch them off your hips with your butt tight to the wall. You contemplate switching into a fresh pair of boxers to sleep in while Beth rambles on about something and places her hands on the small of her back, pushing out her lean tummy while bobbing her head to make her braided pigtails sway. You might have to change sooner than later if your shameless cousins keep parading around like this and flashing you multiple times per day.
Brayden has a longer think than Beth about making himself naked, but when he pushes his underwear down off his butt he confidently shares that he doesn't "need" pajamas tonight.
"Whaddya mean you don't 'need' them?" asks Beth, still nude, but finally reaching down into her bag.
Bray shares a look with you, nodding his head at his sister as if she's ridiculous. "Guys just do that sometimes, Bethany," he replies, one fist propped up on his bare hip as condescendingly as possible with his pelvis pushed out.
"I don't think so," says Beth, squinching her face and pausing to look at the bulge in your boxers before she stands up holding a pair of checkerboard patterned Hello Kitty panties.
"It's not a big deal," counters Brayden, parroting you from this morning while his compact package doesn't swing so much as it shifts and wiggles with each of his gestures.
"I do wear boxers to bed though," a point you illustrate by adjusting them, carefully adjusting your chub for good measure.
Beth glances between you and Brayden before warily stepping into her panties and squinting at her brother with an accusatory glare. "You're not going to do weird stuff are you?"
"No... what are you talking about? What weird stuff? I don't do weird stuff." Brayden got real defensive real fast.
"Don't lie. I always fall asleep after you."
"No you don't!"
"Yes I do, and I hear all those sounds you make in the dark."
"I don't make sounds!"
"Do too! Sometimes it's like a squeak and sometimes you grunt and sometimes it sounds like a slappy thingy."
"I... you don't know what you're talking about!"
It's still quite dim in the room with only one flashlight pointed at the ceiling but you can tell Brayden is starting to blush. He haltingly reaches down towards his stuff, possibly questioning his decision to go nude, but then he doubles down. Abruptly straightening his legs and bouncing his cock, he crosses his arms to stubbornly stare down his barely-more-decent pantied sibling.
"Ungh! Ungh!" cries Beth, lifting her upper lip and flailing her arms and body in an exaggerated display of mockery. Brayden sends daggers back at her, fuming, but while watching her flail he suddenly uncrosses his arms and covers his junk. You were already watching it happen before he even noticed; he's getting hard. At least you're not the only one.
"Shut up Bethany!" shouts the embarrassed sibling as he scrambles into his sleeping bag to conceal his lengthening cock. You follow suit, having been too distracted by first Beth's and then Brayden's striking nude forms to do the same, and crawl into your bed to hide your own semi that has been pushing ever harder against your boxer shorts since you all stripped down.
"Least I'm not gross! You're not going to let him be weird are you?" asks Beth. What a weird position to be put in.
"Brayden... he's, uh... he's in bed, so, y'know... whatever."
"It's fine cuz he's in bed?" Beth isn't happy with that. She reaches into her bag with a suspicious glare, slowly picking up her polkadot princess sleepwear while eyeing the two weird boys in the cabin. In protest, she throws her nightwear across the room and crosses her arms as indignantly as Brayden before her, seemingly upset that her brother is going to do his 'weird stuff' on vacation. "Fine. Then I'm not wearing my nightie. And you can't make me."
"Nobody cares," snaps Brayden, twisting in his bag, his body hunched forward.
Beth huffs and snatches the flashlight, turning it off and clamoring into bed. It's such a saving grace for your own cock to no longer be staring at such an incredibly cute and upsettingly immodest young girl. If Brayden has been jerking off most nights in their shared bedroom back home you wonder how much his sister has to do with that.
A few minutes pass with no one saying anything, not even a single goodnight, only the chirps of crickets and critters through the cracked window filling the tense gap of silence. Then you hear shuffling from Brayden's bag. Repeated shuffling. Specifically you hear the sound of his arm displacing the slick nylon exterior of his bag, the slow soft rustling growing faster and steadier. Then it suddenly stops.
"Why do you have to be so stupid Bethany!"
"I'm rubber and you're glue and all your stuff bounces off me and sticks t-"
"Jesus! What the hell is wrong with you two?! Do you wanna sleep outside?"
"Yeah, make her sleep outside!"
"You'll both sleep outside!"
"What did I do?! He's the one being weird!"
"You're both being fucking annoying!" you bark. That shuts them up, at least for a moment. You can't help but have plenty of sympathy for Brayden if he's only trying to quell his stiffy. That's probably why you have such a short fuse at the moment. Heck, you have half a mind to join him right now and clear out your own frustrations. You'd have to sleep better after. It's wild to think Beth has been listening to her brother jerk off for however long - maybe months - without knowing what he's been doing. Surely she has some vague idea, but she is pretty young too. She might just be that innocent still.
"I shouldn't be in trouble..." Beth eventually mumbles to herself. "I'm not the one going to bed naked..."
"I don't care what you wear to bed!" you snap, wanting this to end. "Be naked! Wear your panties as a hat! I don't fucking care! Just stop arguing about everything!"
That actually shuts them up. Brayden stretches out in his sleeping bag and seems to relax, or at least gives up on rubbing one out tonight. Beth on the other hand tosses for a bit but does not calm down. You can feel her anger emanate from her tiny body, and sleeping right next to her makes her flustered state that much more apparent to you.
Once heavy breaths can be heard coming from Brayden, Beth carefully sits up. She fishes about in her sleeping bag for a moment then pulls her arms out. Although there's no flashlight to aid you, there is enough moonlight to make out what she's doing. You watch her clearly spread her panties between her hands, place the undergarment onto her head, taking extra care to pull her pigtails out through the leg holes, then spitefully stick her tongue out at either you or Brayden, you can't be sure, before fluffing her pillow and laying back down to sleep.
What a fucking pair of roommates you have. You wonder if it's too late to give up your private cabin and bunk with the other kids instead.
"Huh? Ha...! Ahahaha!"
Braden's burst of laughter wakes you up. Peeling your eyes open, you see him standing and pointing across the room, either coming back from or about to go outside to pee. As you lift your head from your pillow he quickly scrambles back into his sleeping bag, still lacking his PJs.
"Oh my God sis, what did you do?"
Beth groggily lifts her head but you can tell she's quickly pleased. "Hmm? Oh... Nuuuuuh-thing."
"Seriously? That's so funny! You're such an idiot!"
Beth scowls and furrows her brow, her bottom lip protruding as she sits up, her panties still firmly secured atop her head. "What's so funny? I don't know what you're..." She pauses dramatically, her hands diving down into her sleeping bag. Then she even peeks inside before slapping her hands atop her bag as if utterly embarrassed. "Hey! Where'd my panties go? Someone's playing a joke on me!"
Brayden continues to make fun as Beth throws open her sleeping bag to reveal not only the fact that she isn't wearing anything, but very specifically that there are no panties to be found anywhere in her sleeping bag, as if she might have inadvertently kicked them off in her sleep.
"C'mon, who did this?"
She does look quite silly playing out a comedy routine with underwear on her head like someone misplacing their glasses, but it's difficult to both laugh and leer while she scrambles naked on all fours along the length of her sleeping bag hamming it up. She really draws it out too, tossing all of her other panties out of her bag looking for "that pair" then demanding to check inside your bag as well as her brother's.
"I didn't do it!" insists Brayden, zipping his bag all the way closed to protect himself.
"Then that means... YOU did it, didn't you, Justice?" she accuses, squatting in front of you with her hands on her knees to bring her face right up to yours.
"Uh... yeah, l guess it would."
Your implied admission of guilt tickles Beth greatly. Flustered, she bounces on her toes for a moment, her squinty duck lips of seriousness instantly breaking out in a smile that she struggles to claw back.
"Well then you'd better give me my panties back mister joker!"
Reaching forward, you pull the Hello Kitty pair off of her head, sliding the undergarment down the length of her pigtails. She allows you to take them all the way off and hold them in the air, comically waiting for her pigtails to stop swinging after slipping free. Holding her mock look of shock more than long enough, she swipes the underthing out of your hand only to ball it up and throw it right back at your face, getting another big laugh from Brayden.
"You big thief! Taking my panties!"
"I didn't take them. They were on your head."
"Yeah, that's true! That's a great prank, Jay!" says Brayden. Beth just keeps smirking as you hand her panties back to her a second time. She quickly puts them on, faking an air of betrayal before finally breaking character and giddily laughing at herself, putting her face in her hands to look embarrassed as often as she twirls about with elation.
That was an unexpected way to wake up.
You're not sure what time it is. The sun is up but it's definitely still early. The brother-sister duo begin to banter back and forth, Brayden wishing he'd taken a picture, Beth saying that "no one had better try that again", while you sit in your bunk and nod your head with their enthusiasm while trying to kill the gnarliest morning wood you can remember having. It's especially hard with yesterday's memories of Beth's spread pussy lips and Brayden's swelling cock swirling through your head, rekindled after watching the younger of the siblings scramble naked on all fours like a sex-addled lunatic, pushing your stiffy all the stiffer. You're astounded that they seem to "bond" over stuff like this. The only bonding you feel like doing right now would involve burying your dick deep inside someone to rid yourself of your unwanted virginity.
Ten minutes later you're still hard. Brayden decides to go pee, suggesting he hadn't before, but isn't shy about showing off his soft cock to his bunkmates as he casually jumps straight up from his bag as bare assed as ever. The moment her brother is gone, Beth decides out of nowhere that you need to help her brush her hair. She was busy undoing her braids while you were all chatting and now sits herself on your legs after handing you her hairbrush.
"Can you move your legs?" she gripes, flexing her butt atop your knees. You warily spread your legs inside your sleeping bag to make room for her. There's only so far your knees can part with your bag still zipped up, but as soon as she slips down between them she wiggles her way backward. You drop the brush and grab her slender waist to hold her off, worried of what she might find if she backs up too quickly, but feeling her soft skin and tiny figure in your hands gives you pause. If anything you end up helping to pull her closer. Not that it matters. She may be on top of your sleeping bag but basically on the ground. It's not like she's in danger of jumping on your cock, and yet she's goddamn close to it too, wedging her narrow butt so far between your inner thighs for the tent your pitching to rise up right behind the small of her back.
"Okay! Start brushing please!"
With a nervous sigh you pick up the hairbrush and do as you're told. Your non-brush hand occasionally helps to pull and straighten her hair, but you frequently find the need to rest it often, placing it on her exposed shoulder, touching her neck, or even - and you can hardly believe you're so pent up - reaching around to her front and bracing your hand against her bared chest to help you "shift your weight" which is more about thrusting your hips into the air behind her long enough to act out what it might be like to have sex, your hormonal frustrations so especially apparent this morning.
When Brayden returns, Beth proudly announces that you're brushing her hair, as if her brother were blind. He rolls his eyes and sulks instantly like he lost a bet. Unlike his sister, you are perfectly fine to ignore him while Beth idly chats to the room, contentedly picking at her nails and wiggling her feet. Brayden quickly gets himself dressed and groans that his sister is going to take forever. You'll brush her for as long as she wants, but when Brayden leaves the cabin in a huff she is suddenly all done.
"Thanks Jay! That was perfect!"
"I-it... was?" you stammer, bending forward and crossing your arms over your misshapen lap after she stands.
"Yeah, he hates when I brush my hair!"
"Oh. Why?"
She shrugs. "I dunno. But it's fun to bug him about it!"
Beth looks to put on her shorts again from yesterday but you never did go back for them. Instead she settles on a pair of light teal knee length leggings. She really hikes them up her waist too, digging them into her crotch and instantly tightening around her pussy mound, a baby camel toe setting in right away. She's plenty pleased by their fit and reveals she has a matching top for it, a tight teal tank that shows a sliver of stomach with the word "WOW" across her chest.
"Wow," you read aloud.
"Huh? Oh! Than- oh yeah! It does say that!" she says, laughing at herself. You wait for her to race after her brother now that she's dressed but she just ogles you, expecting you to get dressed as well.
"Can you... wait outside?"
Beth cocks her head. "How come?"
"Because I... N-nothing. Nevermind... Can you just pass me those jeans?"
Remaining inside your sleeping bag you fight with your pants. Beth thinks you're silly, that it's way harder to get dressed like that, but you continue undeterred. Hoping the tight material of your jeans will hold down your hard on for you until it eventually goes away, you emerge from your bag half dressed to finish putting yourself together, grabbing a random band shirt and fighting your angry morning wood with every bend and step that you take.
When you and Beth leave your cabin together you immediately spot Brayden a short ways down the path kicking at some flowers. Turns out he was waiting for you too. It had seemed like these two had a better start to the morning than they had ended with last night, but they're still quietly fighting over you.
It takes the entire walk down the path for your stiff wood shaft to reduce to a more manageable sprout, but you're thankful for the improvement that makes to your comfort and insecurities as you break out into camp. Several aunts note how cute Beth's outfit is and she hops with appreciation. Breakfast is slow coming but you are happy to wait. You finally get your promised pancakes even if they're a touch disappointing.
There's not as much to do on the third day, the camp mostly having been sorted out by now and the parents becoming ever more leisurely, with the exception of Uncle Dave of course who continues to attend to smaller details and logistics in his own diligent affable style. You try to chat with Nicole for a while but she seems to be in a reading mood, hardly looking up at you over the top of her glasses. By mid-morning there are a bunch of adults sharing stories in their camping chairs but it seems like everyone else has disappeared. You're not even sure where your bunkmates ran off to.
Figuring they might be hanging out at the kids cabin, you stroll across and swing open the door.
"EEEE!"
That scream causes you to freeze. Emma, Asha, and Yulia are all huddled together fully naked in the middle of the room, your eyes bouncing between nipples and butts and bellybuttons. Your brain goes to weird places watching the girls cover and cower while they squeal. Then you notice the swim top in Asha's hands.
"Justice!"
You quickly slam the door and spin around to find some adults glancing at you from a distance.
"Wade? Is that you?" calls Uncle Mike, his joke earning a jab from Aunt Clara. "Whatcha doin over there, Justice?"
"Nothing. They... they're changing." Your discomfort elicits a few chuckles, another joke or two being shared among them at your expense.
"You should try knocking now and then, okay?" advises Aunt Debbie, no doubt alluding to you walking in on Gramsie before. Ugh. Do they all think you're some creeper now?
You shuffle away, head low, just trying to get out of sight. You're about to duck behind a different cabin when you spot your roomies popping out of the tree line with Wade and May in tow.
"Justice! Hey! Over here!" calls Brayden. "We were gonna show off how cool our cabin is! Wanna come?"
"Yeah, Wade wants to see," adds Beth, unsure how you'll react to that.
They want to bring people out to your cabin? The cabin that was supposed to serve as your own private oasis during this stupid camping trip? You must not have made it clear to them that you didn't want anyone else going out there. If people start venturing out there regularly you might never find any privacy! Although if you were able to show how plain and boring it is no one would want to come back.
Set the siblings straight about bringing anyone to your cabin
