Offline/Make your sister even more embarrassed
You're not too worried about Nicole. This has to be one heckuva sight she just wandered in on but she doesn't appear particularly fazed. Yulia looks more surprised than Nicky does, though amused might be more accurate. You're far from innocent here so it would be hard to come out of this without looking like a pervert, but you'd much rather milk your sister's embarrassment than try to defend yourself.
"Aw, it's no big deal, right Emma? Em just wanted to know how to make a guy feel good-"
"What?! Justice!"
"-so Brayden offered to show her."
Nicole bounces a glance between you and "Uh... okay then."
"Yeah, she's real excited to learn. Kept asking for him to hurry up," you add.
"No way! I never... Justice, quit lying!"
"Why would I lie about that? Why else would I let Brayden do that stuff to me? Someone had to show you since you're so clueless and desperate to try. How is it my fault that you want to put your brother's dick in your mouth."
"Ew! Justice! Stop!" Emma protests again, finally wriggling her legs into her bottoms. "Don't even joke about that! I would never! I don't want to do things! Any things!" She stands in a huff, determined to clear her name, but is instantly distracted by her bikini again. The one knot is all wonky after you pulled it tighter so she can't quite get that side past her hip, stuck near the top of her thigh, which means the slanted garment barely conceals her pussy. She starts tugging on the knot while she defends herself, making little progress on either front.
It's fun seeing your sister get all flustered. You look to have Brayden back you up on this but that's when you notice that your roomies have disappeared. They must have ran off to avoid getting in trouble. Did they even look to see who was coming? They must have gotten out of here crazy fast.
"Okay, but... if you weren't doing anything... why were you naked?" prods Nicole hesitantly, like she might not want to know why.
"Oh! It's a game, Nicky," Yulia tries to explain, perhaps assuming this is all related to what they were playing last night. But your sister latches onto that explanation immediately.
"Y-yeah! I only had to kiss him once I got naked and after that I d-"
"Kiss him?" Nicole responds dubiously. She cocks her head and peers over the edge of her glasses, her ponytail grazing her shoulder. "And what're you kissing?"
"No! No! I never... I wasn't...!"
"I'll give you a guess," you chuckle, shaking the bulbous protrusion distending the front of your shorts.
Stumbling over herself, your typically talkative sister can't find the words to explain herself. After giving you a pained betrayed look, she puts her head down and shamefully runs away, flashing a bit of buttcrack as she goes. Nicole tries to apologize and get her to come back, but your sister isn't willing to humiliate herself any further.
"Can you help us, Justice?" asks Yulia, hardly phased by all the commotion. She may be eyeing the bulge in your boxers suspiciously, but she's still focused on why she came out here as she points a finger into the air to draw your attention. "We need to get that down."
Looking up, you follow her finger to find a nightie hanging from a high tree branch directly above you. It seems it's hers and she needs it back lest she get in trouble with her mom. But you're surprised to find a few other items suspended in the air. You're mostly surprised that you failed to notice them before now, though most are really up there. There's a pair of panties, a tank top, and even a teddy bear. A half dozen items are strewn about the branches well above your heads.
"How'd that get up there?"
"Yulia said Wade and Brayden stole it from her last night," explains Nicole, but with her younger cousin suddenly looking more shy, not to mention the curious scene they just walked into, Nicole is less certain of that explanation.
Ready to move past this awkward situation, you grab the biggest stick that you can find nearby and swing it above your head to bat the night garment down. Even with that extra 5 feet it's still well beyond your reach. Julia and Nicole follow your example looking around for sticks and soon start throwing whatever they can find up into the air to knock the article loose. That approach doesn't look promising. Their aim isn't very good, but even when Nicole lands a good hit the nightgown just flaps out of the way to let the soaring rock pass by.
While the girls hurl objects, you follow the sturdy branch back to the tree it's connected to. It takes you a minute, but you clamber your way up the tree until you come to the long troublesome limb. Reaming on the branch with all of your body weight, you shake it with everything you have. After a moment of worry the garment unhooks itself from the twig that had snagged it and falls back to the ground.
"Yay! Thank you Justice!" calls Yulia.
"Call me Jay," you cooly reply as you descend.
It's clear you need to get all of these things down to keep anyone from asking questions. You climb two more trees to free several more items, your cousins watching you work with interest. You feel plenty exposed clamoring about in your undies with two girls watching your every move. However, with the confidence boost of your skillful exploits in the trees - bolstered by all the action you've seen then past couple days - you overcome the initial bout of fear from having to climb so high. With them eyeing you so steadily and you playing Tarzan, all it takes is Nicole referring to your boxers as a "loin cloth" for the bulge in your shorts to make a triumphant return on your way back to the ground.
"Can I try?" asks Yulia, once again blatantly inspecting your bulge, lacking the awareness to do so discreetly.
"Sure. I was saving the easy ones for last anyway," you boast.
You help Yulia up into the tree to retrieve her sister's teddy nestled between two branches all of 10 feet up. She's not much of a climber, but you support her until she gets her bearings, pushing her butt higher until she's above your head. When you let her take over you're staring straight up under her dress. A pair of pale purple panties present themselves to you as the above-the-knee dress, hanging away from her body, flutters freely and lets you see all the way up her back. It's an interesting perspective, one that keeps you directly under her to encourage her progress, watching her thighs split wide to reach the next branch.
"What were you really doing out here."
Nicole's question startles you. The bulge in your boxers is growing bigger and you step back from the tree with a sheepish grin to answer her. Since there's no one else to contradict you, you take this opportunity to claim that the others were showing you what they did together last night in the forest. It's a weak way of distancing yourself by making them look a bit worse. She contemplates that explanation with a curious pause and, with evidence still in the treetops proving it wasn't a quiet night, she doesn't question you further.
"You are a weirdo, though," she states.
"Pees in a pod," you rebut, waving up above your heads just as Yulia tosses down her sister's teddy bear.
Nicole decides to take a crack climbing the last tree while Yulia struggles to get down. You attempt to guide the timid girl back to the ground, telling her which branches to step on, but then it gets complicated. A twig snags the bottom edge of her dress as she descends, lifting the flowy thing well past her butt before she notices. That makes her freeze, too scared to let go of a branch to try to turn and free her dress and too embarrassed to climb any lower.
You can barely reach her ankle now and assure Yulia she's really close. After a bit of coaxing you convince her to jump down to you, promising you'll catch her. Little Yulee squeals when she hops away from the tree, hands in the air, suddenly in freefall. You catch her just like you said you would, but when she crashes into your arms you unexpectedly wrap around her pantied butt and bare back. Your hands aren't just under her dress; she's not even wearing it. The missing article falls to the ground a moment later, the light garment springing off of the branch it was snagged on once her body slipped free and was no longer pulling against it.
"Nice loin cloth," you tease. Yulia looks a touch mortified but she still giggles at your joke as you hold her while both of you are wearing so little. "Good to know I'm not the only Tarzan."
"You're Tarzan. I'm Jane," she counters.
"Ah. I never watched it," you admit, putting Yulia down and stepping aside to retrieve her dress for her. "Does Jane swing through the trees in a loin cloth?"
"No! You do!" she grins, her hands trying to cover her panties.
"Oh. If she doesn't, you should take yours off then."
Yulia thinks about that for a moment, then prances and shakes her head once she gets your joke. "No! No! I didn't mean it like that!"
You smile and hand over her one piece of clothing, watching her giggle as she turns it right side out. Yeah, you know how young she is. She's tinier than Beth even. But seeing any girl standing out in the sun in just a pair of panties really does something for you. So you look on with interest as long as you can, eyeing up the small purple bow sewn onto the frilly waistband and her bright pink nipples adorning her rectangular frame, trying to chat her up and make her laugh some more as Nicole returns with the last rescued article.
Yulia gives big thank you hugs to both of her big cousins before you head back to camp. You're almost used to strolling around in your undies by now, like it isn't actually a big deal, but you suddenly feel very underdressed when you find yourself in front of all your aunts and uncles again. Discovering most of the other kids have gone swimming, you trot out to your cabin to change into your swim trunks. You admit it's silly that the cut and fabric of a garment can so dramatically change how you feel about others seeing you wear it, but you'd still much rather swim in trunks than boxers.
Down at the river, Beth and Brayden are splashing about with Wade and his little sister Gem and you run into the water to join them. Wade is wearing shorts but Gem is just in a diaper, one that looks to have swelled up and gotten heavy after trying to absorb the entire river. It hangs off her hips and keeps slipping down her butt, Gem excitedly and uselessly tugging up on it as she kicks through the water.
You try to ignore the young one and keep splashing the others, but Gem grabs your attention again by crashing forward into the shallow water. When she picks herself up, her diaper is at her ankles. She steps out of it almost by accident, rising out of the water to charge at you with a wild scream. The naked little girl leaps forward and slams herself into your leg then wraps her arms around your inner thigh, latching herself onto you. You try to pry her off arms off one by one but she just laughs and regrips you.
"She can swim, right?"
"Sure," Wade replies with a shrug.
It's a weak confirmation, but you drag Gem out into deeper water. When it gets up to her neck she starts to climb you, letting go of your leg in favor of your arm instead. That's when you grab her. The young thing cackles stupidly as you hoist her into the air before launching the cute little bare assed girl into deeper water.
Gem thankfully pops her head out of the water a moment later. You were just about to dive in to make sure she was fine. You'd hate to have drowned her because Wade is a jerk, but it seems she can actually swim. As the others laugh, Gem starts doggy paddling after you, squealing that she's still going to get you.
You turn toward the shore to add some distance when you spot Auntie Grace wearing a familiar bikini with two little blondies accompanying her. Yulia strips off her dress while talking Grace's ear off. May similarly strips down to her panties, patiently waiting for her sister to finish her story. But as you get closer, with Gem closing the distance behind you and rising higher and higher out of the increasingly shallow water, May watches the two of you splash and squeal and becomes inspired by how your pursuer is dressed.
Dropping her panties in an instant, May embraces the skinny dip without a second thought, then races at you head on. You're not sure how you managed to get two naked little girls chasing after you, but it doesn't last long. You don't even need to dodge as May buzzes right past you. It turns out she wasn't interested in chasing you; she was looking to get Gem.
May jumps on top of Gem and tackles her, both of them crashing into the one foot deep river's edge. At first Gem is upset, but she's quick to come around, the two nude girls giggling and splashing up a storm before forgetting what they were doing and ambling through the shallows no higher than their knees trying to look for minnows.
Yulia finishes her story and you watch the purple pantied prepubescent pass the nude youngsters on her way to join the others. But just beyond them she stops and inspects her sister, contemplating something. Whatever thought she had brings her to turn around. Yulia returns to shore, strips off her panties, and becomes the third young girl to get naked for a swim. That leaves you standing on the beach by yourself ogling multiple marvelous mons of your youngest little cousins. You're beside yourself that they would all shed their clothes so freely. Yulia was embarrassed to be seen in her panties a minute ago, and yet here she is in front of way more people with her pussy out.
"You really do like watching, don't you?"
"I..." Fuck. You're not even pretending to do something else. You're just staring down 3 naked little girls while Auntie Grace is right here on the beach a stone's throw away. You step closer to her and try to defend yourself. "I just... don't know why Yulia took off her panties. She was about to swim... but she stopped..."
"May lost her underwear yesterday."
"Lost?" You're instantly confused. Is she not allowed to wear them?
"When they were swimming in the river," Grace clarifies. "So I wouldn't blame them if they don't want to lose another pair."
"Oh."
You follow Auntie's gaze out into the river. Yulia has reached the diving rock but needs a hand getting onto it. Wade is quick to offer two, lifting her out of the water by her butt cheeks and pushing her onto the rock on her belly. He doesn't let go though, pinning her in place and spreading her bum wide. God, he is such a little pervert, isn't h-
"You're still watching..." Grace reminds you.
"But... You said that's okay, right? If all I do is watch."
"Not exactly what I meant..." she notes, alluding to who it is you're watching. "You can't just stare at anyone. There are rules you know. Besides, not everyone feels the same way about that sort of thing."
"How do you feel?"
"Like you haven't gotten in trouble yet," she replies with a cheeky grin. "At least those girls out there don't care."
"And what about... the other girls I saw today?"
She smiles. "Well this one noticed you, but I don't mind being watched." As she says this, Auntie Grace proves her point by untying two of the strings of her bikini and discarding her top nonchalantly on the ground, baring her already tanned tits to the sun. "But I think you got away with it. Jet didn't stop anyway. That would've been a shame. I'll admit that I also enjoy watching from time to time... I'm kinda surprised though."
"About what?"
"That you chose to sleep in a cabin out in the woods all by yourself if you really enjoy 'watching' so much. There are lots of cabins you could be watching."
What does that mean? Sure there aren't any cabins around yours, but would you want to creep on anyone else? Does she know something you don't? Are all the parents having sex out here or something? Would you want to watch that? If you're trying to come off as less of a creep it's probably best you avoid asking about it, especially if it's an innocent comment.
"I'm not alone. I have Beth and Brayden with me," you share. It's a plain fact, although in the context of this conversation you almost feel like you're oversharing. You hope she's not taking it in a weird way. "What I mean is I'm not lonely or anything. Besides, there's benefits to having no one else around."
"Like what?"
"Well... it's a lot harder for someone to accidentally watch you do all sorts of weird stuff."
A mix of emotions crosses Auntie's face. There's embarrassment, amusement, maybe even some sourness, but she stops the fleeting emotional rollercoaster with an odd gleam in her eye. "Is it...? I suppose I'll keep that in mind."
With that, she rises from her private rock and steps out into the river for a topless swim. Suddenly you feel obligated to watch, especially after she checks over her shoulder to make sure that you are.
Sitting down on the shore, your cock becomes restless while you stare out over the water. Gem and May are quite close to you, happily strolling nude through the shallows on full display. Auntie Grace doesn't stray too far either, finding water just deep enough to do the backstroke, her beautiful tits sticking up out of the water as she calmly pinwheels her arms behind her head. Yulia sticks close to Beth as the rest of them take turns leaping from the diving rock, but she continues to let Wade help her out of the water whenever she can't pull herself up on her own.
Having full permission to stare, you do far more of that than swimming over the next hour, happily drinking in the sights from a safe distance. You're usually stealing glances - and feeling guilty doing it - so it's so satisfying to sit back and take it all in.
When lunch comes there's some murmerings among some adults about something. They're acting kinda cagey. Looking around to figure out why, you notice Wade is suddenly absent. It's lunchtime, so that seems weird.
Mom pulls you aside and asks if you know about anything that may have happened in the kids tent last night. You firmly deny knowing anything and immediately flip the question back to her, asking her what happened out there. She just says rumors, probably nothing, but your non-answer does satisfy her curiosity, insofar as you have nothing to tell her. And you don't. Not really. Sure, you did see some stuff outside of the tent, but inside? You don't have a clue.
You manage to catch snippets of the adult's conversation; Aunt Becky asking if the tent should stay up, Aunt Clara assuring that they don't know if anything "really" happened, and your dad shooting down an idea to rework all the sleeping arrangements. You have to assume all the adults have been asking their kids about last night the way they're talking now. You wonder what caused all of this ruckus. Looking around you realize you can't see Wade's sister anywhere either. Their mom is often in a cabin with a screaming baby, but those two are usually wandering around as they please. Meanwhile their dad is drinking next to the main fire pit, unconcerned, dismissing all the commotion as overreaction.
Did Wade do something? Did his little sister say something? You don't know, but you want to steer well clear of all that, especially since you suspect your sister might be in the middle of it too, assuming this is from something that happened last night.
After lunch, B&B confront you about the tent. You're quick to shush them and drag them away from anyone else's earshot, not knowing what they might share or how anyone nearby might interpret it.
"I told Brayden it's my turn to stay in the tent but he's being a dumb dingus!"
"That's probably not a good idea, Beth. Ther-"
"Yeah, you're too whiny and annoying," Brayden quickly snips. "No one would want to sleep with you."
"That's not wh-"
"Nooo! Justice! That's not faaair! He got the tent last night! Now it's my turn!"
"Guys! Shh! Shut up!" you insist, not wanting them to raise their voices.
"C'mon! Please-please-pleeease!" Beth continues, wrapping her arms around you and hanging from your waist, her chest pressed against your junk.
They're impossible. You were going to tell her that neither of them should go out there if some of the adults are getting suspicious. Maybe Wade is the perfect scapegoat and the adults will be satisfied having him separated, or maybe they know better than to leave the kids unsupervised now. Though you're pretty sure Beth isn't going to be satisfied with anything less than matching her brother in all things, and part of you really wants to say yes to her just to keep her happy, especially with the way she's looking at you right now.
