Offline/Then take your panties off
"What?" she asks astounded.
"You can only see your panties through your dress because they're white. So take them off. Then the dress will be one color again. You help with the dishes and after that you can get changed."
"Really?" she ponders aloud, seriously considering it before shaking her head. "I can't just take..." she lowers her voice and leans in. "...take off my panties in front of everyone."
"Well duh. Do it in the outhouse. Or behind a cabin or something."
"And where would I put them?" she asks, gesturing down at the single layer of fabric hanging from her body.
"Just give it to me," you offer.
"You don't have pockets!" she points out observantly. "You can't carry my panties around."
"Then we’ll put them in my trunks," you offer. "But if you don't want to get in trouble for not helping then you should probably pick something already."
She chews on her lip a moment then drags you away. You move to the side of camp with the fewest people and duck behind a cabin. Nicole stops and faces you before lifting up the sides of her dress and slipping her hands underneath. You didn't think she'd do it right in front of you. You watch the white blob at her crotch move down through her dress until the fabric comes into plain view just above her knees. You're already getting hard as she steps out of her panties, excited by how crazy this is and the knowledge that one thin little layer of material is all that's covering her.
You're about to make a sassy comment to tease her but her expression suddenly becomes panicked. She takes a lunging step forward and shoves her panties down the front of your trunks, the back of her fingers tapping the shaft of your thickening cock. She walks by you after making her quick deposit and you turn to see someone move away after placing a storage tub down around the corner of the cabin you’re using for cover.
You should probably be a little more worried about the prospect of being caught watching your cousin remove her panties in front of you, but the fact that said cousin just shoved her hand down the front of your shorts distracts you plenty. Grinning, you peek around the corner of the cabin and watch Nicole stiffly walk away, arms straight down. It sorta looks like she's squeezing her thighs together, as if she were holding something between them or trying not to pee. Thankfully for her it's a pretty short walk back to the picnic table and she doesn't have to hang around there for very long before she's put to work.
It's not that you want Nicole to be uncomfortable or nervous or anything, but it doesn't bother you much either since you know why she's like that. You kinda like it even, her jittery nerves, her reluctant participation, her panties caressing your cock, all of it. You slowly circle around the outside of the camp so you can watch her squirm from a distance, doing your best to stay outside of the chores vortex emanating from the picnic table. The adults unfold a little dishwashing station and load a couple of plastic bins onto it filled with water to wash up with. Nicole and her mom take their positions in front of it and attack the dishes that have already piled up. The two of them start chatting, although her mom seems much more talkative. Nicole soon notices you circling with your stupid grin and shoots you a glare but she can't completely stifle a grin of her own.
At first Nicole keeps shifting from foot to foot, angling her knees inward and tapping or rubbing her feet together. As the minutes tick by you notice her loosen up though, getting gradually more comfortable in her minimalist outfit or at least more secure with the idea that she won't get caught.
You really want to see through her dress again but, despite how perverted it was, your stripping suggestion did actually help to some twisted degree. After staring tenaciously you convince yourself you can spot her buttcrack from behind but it's honestly a tough call. There are two tiny points on her chest that you are convinced are her nipples but you’re sure they didn’t look like that before. And despite the sun shining down on the front of her body you can’t see as much as you could when you were eating together. What you are able to pick out are the top half of her legs along the edges of her silhouette, but only from the back thanks to the sunlight carving her shape out of the shadows.
The two boys from earlier seem similarly enamoured with your cousin though. The dishes three quarters done when they both start buzzing around the picnic table. They keep walking past Nicole, right behind her, staring at her butt. They’re probably trying to figure out where the word went. After a while one of them gets brazen. He slowly moves closer, trying way too hard to not look conspicuous. You walk up and scare him off just as he was gingerly lifting the back of Nicole’s dress to peek underneath.
"Done yet?" you ask Nicole, glancing at the boys running away.
"Almost."
"You can go now sweetie," her mom answers. "Thank you for helping, and again I’m sorry for embarrassing you."
"Thanks," is all Nicole says, drying her hands and slipping away with you. Nicky leads you back behind the cabin again, lightly skipping and twirling as she pulls you along.
"You know, if taking off your panties made you this happy you should probably never wear them."
"Shuddup," she says with a smile. "I can’t help it. I just feel so... naughty."
"Yeah? I can just hold on to this then," you tease, tapping your junk.
"Um, no. That’s fine. You can give it back now."
Staring at her with an evil eye, you say, "Make me."
"I don't need to make you, I can do it myself!"
She takes a step toward you and you push her away. So she tries to make a lunging grab at your shorts instead. She barely snags the front but you shake her off. The two of you start grappling like you did a couple days ago. You try to turn her to the side but Nicole expects this and uses your move as a way to get closer to you. You’re taken off guard and step back, a little intimidated by just how close she’s trying to get. She backs you up against the side of the cabin then cranes her neck up to kiss you. Her hand deftly slides inside the waistband of your trunks while you’re distracted.
"See? I can do it all by myse-?"
"What are you doing?!"
God fucking dammit Emma. Why are you so loud?
Nicole pushes away from you, instantly shaking with fear. "No! I just..." Nicole brings a finger up to her lips. "Shh... please?" Nicky begs. Truly trembling, she almost looks ready to faint.
Your sister is just standing there at the corner of the cabin doing nothing. You step over to her and drag her closer so she’s concealed from the rest of the camp.
