Incest Seduction/Get Kalli naked so everyone can see how good you look
You need to do something drastic. It so not fair that everyone is treating you like some toddler. It's not your fault that you're the baby of this family. Yeah, the Taylors saw you as a little kid, but hello?! Are they going to see you as the baby of this family forever?
You think about it for another moment, trying to make sense of it. Yeah, maybe you're still struggling in the puberty department, and maybe you're on the short side for your age, but even without mom's curves or Dawn's boobs you're sure that you could compete with either of them. Probably. You definitely don't still look like this hyper little girl running around the kitchen... do you? No! Of course not! And you can prove it too!
When Kalli swings past you again you step out in front of her behind the island and grab her by the shoulders. As you take a knee to look her in the eye it's clear she thinks she's in trouble now.
"Okay spanky," you start. That gets a smile out of her. You continue, slipping off your gloves, "We have to fix something."
"Fix what?" she asks.
Showing instead of telling, you lift up her nightie and quickly yank her panties down. Kalli's expression returns to that knowing yet unsure naughty look that she had when she first saw you standing naked at the front door. You're not playing around though. With her underwear at her ankles you pull at her nightie again and lift it higher but that's when her reflexes finally kick in and she pushes down to cover herself.
"What're you doing?" asks Kalli smiling, actively fighting with you for her nightie. There's no way she's stronger than you but you just can't get this dumb thing up past her hands.
You grumble and yank, angrily muttering, "You... have to..." then stop yourself, letting go of Kalli. You really just want to rip the stupid thing off of her, but your short emotional struggle gives you just enough time for you to realize there are other ways to make this happen that don't have to involve assaulting her. Smoothing out her sleepwear, you instead cheerily explain, "You have to take off your clothes if you want to spank me."
"Really?" Kalli thinks for a second before lifting her feet out of her panties that you dropped to the floor. Then she pauses, looks past you, and asks, "Can we...?"
"I don't know," answers Aidan, surprising you from over your shoulder. "Mom probably wo-"
"Jesus. I mean... Duh? I'm naked," you flatly note, not bitter about this fact at all. This fact doesn't somehow make it okay for them to get naked, but Aidan just examines your body as if the answers are there somewhere. You turn back to Kalli and slowly explain. "Listen, I know you want to spank me, but you have to get naked if you wa-"
"You go first!" Kalli shouts at her brother while anxiously playing with her sleepwear. She didn't need much of a reason to get on board. Aidan does not look as excited.
"Um, well... I guess I... I'll do it if you do it," he flips, throwing it back on his little sister.
"Okay!"
Kalli enthusiastically shimmies out of her nightie without a second thought. She holds the item in front of her for a few seconds before dropping it to the floor excitedly, all kinds of giggly with a big nervous grin. And as she smiles you frown.
It's kinda frustrating to actually be able to compare yourself to this little girl now that you're both naked. She's surprisingly trim without much of a belly, something that doesn't work in your favor, and her body and limbs are so well proportioned that it's hard to age her right away. Obviously your legs are longer, but you don't have the typical figure of most teenagers. Worse yet is mom's insistence on getting you into waxing. Now Kalli's smooth compact little pussy even bears a striking resemblance to your own tight lipped vulva, at least at a glance.
"Come on! You promised!" urges Kalli at her brother's lack of action
"I know..." he replies, trailing off while making no effort to do anything.
"You just take it off," Kalli instructs, as if her brother doesn't know how to undress. Going even further than that, the helpful little sister steps forward and tugs at her brother's pajamas.
"Yeah but... just wait..." Aidan bats at Kalli's hands, glancing around at the conversing grown ups nearby.
It's going to take forever like this. You opt to help Kalli out. As soon as you join in Aidan struggles far less. The two of you girls manage to guide Aidan's pants down his legs and force him to step out of them. Then you both work on his buttons, freeing them one by one until the bottom one opens and exposes the cute little cock hiding beneath the bottom edge of his top. Seeing his little boy junk only reminds you of your inexperience and how you've never even seen a "real" penis before. Not that Aidan's isn't real, but it sure isn't very big. Can younger boys even get hard like older boys? All you can remember from that terrible sex ed class a few years ago was snickering with some other girls when they started talking about penises.
Aidan is totally submissive at this point and hardly even complains when you slip the opened shirt off of his shoulders and down his arms. Once he too is naked he just stands there looking down at his body. He's also unsure of what to do with his hands but only briefly tries to cover himself, instead nervously scratching his legs and rubbing his arms.
And just like that there are two other naked kids beside you. Not exactly what you were intending on, but it's fine. This has to work now.
"Hey everyone, look who else is naked!" you announce, quickly guiding Kalli out from behind the island and into the open so the whole room can get a good look at the two of you. Her brother also wanders out close behind.
"Kalli!" Tracy exclaims with a scolding tone, but then very quickly gets flustered. "What are y- Aidan! You... you're both...?! I'm... Kara, I'm sor-"
"That's so cute!" gushes your mom. "Isn't it cute dear? They want to be like Kimmy!"
"Very cute!" echos your dad. "Right son?"
"Yeah. I suppose so," agrees Zack.
"Now that is true friendship! Tracy, isn't it adorable?"
Mrs Taylor tsks. She had looked like she was about to order her kids back into their clothes, but she's thrown by your family's positive comments. "I... I'm sorry Kara, this isn't like..."
"You shouldn't be sorry! You should be proud! My little Kimberly had to work up so much courage to have me invite you over to show off her new lifestyle." Mom pauses to give you a big shit-eating grin. She phrased that like it was all your idea without actually lying. You bite your tongue as she continues in a slightly hushed tone. "Besides, we don't want to turn it into a 'big deal'." Your mom adds some actual finger quotes to drive that home. "I think it's just perfect! The kids are having some harmless fun together, right?"
Tracy, now questioning herself, turns from your mother and looks to her husband for his take on all this. He's wearing a grin but just shrugs.
"Yeah, it's, uh, harmless nudism, right Kara?"
"Exactly!" beams mom. "Nothing more natural!"
Richard nods. "They do bathe together. And Kimmy... Kimmy just looks..." he pauses, giving you a good eyeballing. There! That's what you were hoping for, to have someone fina- "Well they just look like sisters, don't they?"
...
What?!
Kalli hugs you around your waist, squeezing you tightly, while managing to headbutt one of your barely A cup boobs.
"They really do! Oh, it's just too perfect. Here, let me take a picture."
A flash goes off before you can even object. "Mom! Seriously?!"
"Ugh, you weren't even smiling," she notes, shaking her head. "I know you kids don't like getting your picture taken, but can't you for once in your life smile Kimberly? Especially in front of guests."
"I'm not a kid, mom," you grumble, staring daggers,.
"Of course not, sweetheart, you're such a big girl." The condescension drips off mom's tongue. "Now give Aidan a hug too, we need to see all three of you."
The flash goes off again as mom steps out for an even better angle. Aidan shuffles up to your opposite side mostly looking for protection. You want to yell and shout and complain so badly but it suddenly dawns on you that mom wants you to do exactly that. She's trying to break you, isn't she? She's trying to make you lose the bet. Well nuts to that! You wrap your arm around Aidan's shoulders, pulling him closer, then curl back your lips into a mostly involuntary sneer for another flash.
"Come on Kimmy! I still don't see a suh-my-ell!" sings your mother.
You don't know why your pussy is still so wet, but having everyone stare at you with two other nude bodies pressed against your own has brought your nipples to tighten and poke out, one right against Kalli's face. Crossing your legs in the hope of a tiny bit of modesty, you cock your head to one side and force an insincere but passable show of teeth while you can feel your cheeks burning a crimson red. Kalli adds a big happy "Cheese!" as another burst of light bathes your body and adds to the spots in your vision, forever documenting how proud you all appear to be of your small nudist troupe, with you sandwiched between the neighbor kids utterly threadbare.
"Hold on, I need one without the flash." Mom takes another step and leans down for a close up. "Sorry if I'm in the way, I'll be fast!"
Looking past your mom you now realize that Aiden and Kalli's dad also has his phone out, as if everyone needed their very own proof of your humiliation.
"Why do you need so many?" you ask through clenched teeth.
"Because you kids grow up so fast sweetie and we have to capture these memories somehow. I also need plenty of angles for my scrapbooking."
"Mom! You can't scrapbook me lik-!" you stomp, a little too demanding of a tone, and quickly cut off by your mother.
"Of course I can! I gave birth to you! The least you can give me is a scrapbook!"
"Ew!" you frown. "Mom! Gross!"
"That's enough attitude missy. Don't think I won't straighten you out. And if you really don't watch it I'll have Kalli spank you some more!" She adds with a goofy smile at your 'sister'. The young girl beside you can't help but chuckle at the thought. "Now are you going to behave or do you need to go to your room?"
"I'm fine!" you declare with a huff. You're so right, she wants you to crack.
"Alright then, all done. Good job." Mom steps forward to plant a firm kiss on your lips, possibly as a distraction since it allows her fingers to tuck into your armpit and her palm to cover one of your underdeveloped boobs without you noticing. Mom slowly closes her thumb as you kiss, her hand squeezing your slight chest and rubbing your pointy nipple. The kissing and groping work together to briefly make your clit tingle with excitement, all of which sends a shiver down your spine. But mom is just teasing you again. She quickly shifts to Kalli and tickles the girl's side before walking away. "You three go back to playing like before."
Well that didn't manage to prove anything. But it sounds like you've gotten out of finishing your chore/punishment now, even though only one spot on the counter is especially clean. You let go of the kids but Kalli has been diligently waiting to follow up on the entire reason she got naked in the first place. As soon as her small hand makes a loud smack against your bare bum the girl laughs and runs away from you. Aidan immediately runs after his sister and you're left standing naked, alone, and thoroughly embarrassed in the middle of the room while Mr Taylor's phone continues to be trained on you. Mrs Taylor meanwhile has stood up from the island to follow your mom around to the counter.
"I'm so sorry about Kimmy's attitude, Trace. Your kids are much better behaved than mine." Your mom leans down to snatch all kids' clothes you discarded on the floor.
Tracy, still taken aback by everything, waves her hands dismissively. "No! Kimmy is... clearly my kids aren't perfect either."
On cue, Kalli races up behind you and quickly places both hands on your ass before running away in a fit of giggles.
"Nonsense!" Mom insists, shoving the scattered sleepwear into a cupboard. "They're angels! Look at them, having a blast, so carefree."
"Did you know your sister was a nudist, Zack?" asks Richard while poking at his phone.
"Nope! No idea. But if that's what makes her happy."
"Y'know, I think this can make a lot of people happy." Richard taps his screen and finally places his phone down.
Your brother walks over to you, bringing you to hold your breath. He looks like he wants to give you a big supportive hug, but after hesitating to even place his hand on your shoulder he just pats your head instead.
"It's like there's this whole other side to you all of a sudden."
Two more spanks land on your ass as Aiden and Kalli round the kitchen and speed past you with joyous laughter.
"Well there's the back side!" jokes mom. Everyone lets out a nervous chuckle at the youthful energy zipping around, but the fact that you're at the center of it all is getting to you. You're half mad and half just desperate to run, all of your frustrations getting close to boiling over. You either need to get some control back or let it all go and try to have fun.
