Offline/Get dressed and wait for the girls to calm down
Tossing Emma's soiled t-shirt beside the cabin, you go in and get dressed while the girls are frolicking through the forest. They stick tight to the clearing directly around the cabin if only because it's hard for them to galavant through the much thicker surrounding bush in the nude. You lay on your bed again, continuing some of your sketches but mostly just doodling images of naked girls. They come back inside only after far too many minutes of crazy and decide to sort out their clothing, hopefully having worked (some of?) the insanity out of their systems.
Asha finally opts to take back her bikini bottoms after running all this way from the water to get them. But now Emma has a change of heart and begs to wear the full bikini instead, perhaps wanting a real swimsuit in case you head back to the water later. They go back and forth on this but Emma eventually convinces Asha to share, the latter of the two willing to give up the bikini top. Putting on their separate halves, Asha pairs her bikini bottoms with the tank that Emma was wearing as pants and pulls it on as intended. Emma slips back into her overalls from earlier in a huff, very notably without panties, perhaps spiteful about not getting the full swimsuit experience she wanted.
Asha digs around and finds a small pair of spandex shorts for herself to go up over her bikini bottoms. You're not quite sure why they're needed as the shorts barely cover more than her bikini, but you don't recall the shorts being quite so small on your sister. It's clear that Asha's body is a bit 'fuller' (or that your sis is real scrawny) when Asha turns away and you see the stretchy shorts hugging her butt very tightly. It's not hard to imagine that if her bikini bottom wasn't in the way and the shorts were a tiny bit higher they would sink themselves deep between Asha's round little butt cheeks like at the volleyball games you sometimes watch after school.
Surprisingly Emma declares herself dressed, donning only the top half of a bikini and the star decaled overall shorts that hardly cover her body. In your mind she's some lipstick and eyeshadow short from looking like a slutty little grade school hussy, but she'll probably look more normal to everyone else especially since she was already walking around like this without any sort of top earlier. Asha isn't as weird looking to you, but everything she chose is skin tight. You're not complaining, but you assume they're going to dinner like this and you hope it doesn't raise questions.
Your assumption is quickly proven correct when the girls ask to go back to camp. Walking out with them amongst the main cabins, it sure seems like the girls are raising some eyebrows. You want to guess that's caused more by Asha's tight clothes than Emma's exposed skin, because who would want to look at your sister anyway? Besides you that is. But in reality this is probably just you feeling a little on edge after what you did with them this afternoon.
The girls are still a little hyper, outwardly acting weirder than normal which is saying something for these two. You try to distance yourself from their crazy since they keep trying to make a scene. They're laughing too hard and grabbing each other a lot and keep randomly running over to you to shove, hug, and even lick you for no reason at all.
You chat up your cousin Nicole who asks if your sister has always been so weird. You can hardly answer before Asha and Emma interrupt with a flurry of running and squealing, your sis jumping up onto your back. With a lot of adults around, you try to shoot them down and sound stern without being mean, at least to make it seem like you're in control of this whirlwind, but in all honesty you kinda like the attention. Your mom pulls you aside at one point and asks you to be extra watchful with the girls and to remind them who's in charge if they get out of hand. "And you have my permission to drill that into them if they don't listen," she adds, unaware just how much drilling you've already done.
Once dinner is over with (thankfully less of a spectacle) Emma asks if you want to check out the kids tent. You're not exactly busy. So the three of you are lead through some thinner brush by a younger girl, Yulia, to a tent pushed out into the brush by itself. It was just visible from camp and a decent enough size for a few kids at least. You hear from Yulia about how all the kids sleeping in the cabin with Asha came out here after her incident. That would've been cramped, but it was apparently lots of fun that night with a game of truth or dare away from all the grownups.
She goes on and on for a while, bragging about how she was put in charge that night, about how much she gets to boss around her little sister May out here, and how she convinced her sister to throw her panties away while they were swimming. That's when you pay more attention, interested how that went down. Supposedly May was complaining that she couldn't swim as far out as her big sister. Yulia explained that panties are too heavy when they're wet, neither girl having swimsuits, and that she'd float better without them. The gullible girl was quick to strip off such a weighty garment and mistakenly let it float away, carried down the river in short order.
"But May ruined everything. Mom says we shouldn't've even gone swimming 'cuz we don't have suits."
"Ash! We can help! Let's give her your swimsuit!" Emma excitedly offers. She doesn't bother confirming with her friend, just stretches the string tied behind her neck up and over her head, the triangles covering her nipples falling forward. "Come on Ash! Take off your half!"
Asha does as ordered, pushing her shorts just off her butt to expose her bikini bottoms. The bikini is a typical side-tie and Asha takes advantage of that, undoing the knots holding her bikini up with her shorts barely lowered.
Your sister is less aware, if not just airheaded. With her top already flopped forward, she tries to tug it up her body but her coverall straps are in the way. So she shrugs off one strap and then the other. The loose denim shorts, with nothing else holding them, quickly slip their way down her skinny body. She only pretends to try to grab them, then closes her knees while blushing. Her privates on display, she lifts her arms and wiggles out of the still tied bikini top. Yulia giggles at your naked sister while accepting the paltry top as the overall shorts settle at Emma's feet. You glance around, worried someone might see. Asha slips her untied bottoms out from her shorts and passes those over as well.
"Put it on!" insists Emma, crouching down to locate her straps. Yulia almost strips down right there, but after a glance at you ducks into the tent and spends several minutes inside with no evidence of progress. Emma and Asha begin to chat away, unconcerned. You ask Yulia if she needs help, and you ask the girls if they want to do something else. No is the only reply you get.
