Hot Summer Job/Stay in the living room
"What does 'mess around' mean?"
"I dunno. Anything I guess. We could play pokemon again!"
"Oh... Sure. I guess we could do that."
Larissa exuberantly races from the couch and grabs the decks the two of you built yesterday. She immediately starts to dissect her deck and make all sorts of substitutions. You're not about to let her get some sort of edge, optimizing her deck against yours, so you too begin to swap out cards and reassess your deck's design.
You are both still subbing out cards when you hear footsteps on the stairs. Every fibre of your body wants to twist your head toward that sound and watch as Kylie descends from her solitude. But you manage to hold out for a few more seconds, wanting to casually look to the side to 'accidentally' see as much as you can see of her all at once.
But today is not your day it seems. The amateur nudist is fully clothed with a typical pair of khaki shorts and a t-shirt concealing the amazing sight you were witness to yesterday. But she isn't descending anymore. She's ascending. Maybe she forgot something in her room.
You get back to whether or not you want Jigglypuff over Dugtrio, Larissa's animated and narrative self-analysis of her deck a humorous distraction from your other distractions. When you hear Kylie on the steps again a few minutes later you think nothing of it.
"Riley? I didn't know you'd be here."
You look over to see Kylie with her phone. But she's changed. She's now wearing a loose bright pink racerback tank top. And that... is all you can see. The tank covers all of her front but barely any of her thighs. She could be wearing something beneath it, but that's hard to imagine. The thin shoulder straps dive rather deep in the front, the curved hem dipping just between her small breasts. The arm holes appear to droop just as far, exposing half of the side of her torso which is hidden only by her slender arms. That pretty well exposes the lack of any kind of bra or undershirt, if her somewhat immodest cleavage didn't already give it away.
For a moment you think this is just a loose fitting tank, but you quickly clue into the fact that this isn't a long baggy top at all. This is Carrie's top. Kylie changed out of her own clothes and into her mom's ill-fitting baggy tank top. And since the tank is clearly several sizes too large for her you question why she would have ever changed into it.
"Mom told you yesterday," Larissa promptly reminds her sister.
"Yeah, but she didn't say when. I only just got up," she says, dramatically scratching her head through her short red hair. "But mom should have told me," she continues. "I could have been naked!"
"Like yesterday..." Larissa whispers to you with a smile.
"Did you sleep well?" you blurt out, hoping Kylie didn't hear her sister's comment.
"Not really. It's sooo hot," Kylie whines stretching her arms out, managing to lift the bottom edge of her shirt a solid inch higher in the process. "When I go to bed I can barely wear anything at all. See?" she adds turning a full 360, her arms still out to the side for emphasis. Her slow turn gives you two brief flashes of side-boob through her open arms and lets you appreciate the smooth gentle curve of her back with the sloping cut of her top.
"Yeah, I do. That looks so... comfortable," you reply, carefully choosing your words.
"Thanks! I think so too." Kylie examines the coffee table where Larissa sits across from you, same as yesterday. "She has you playing Pokemon?"
"What's wrong with Pokemon?" Larissa asks defensively. Kylie just shrugs. "Well we like it," notes Larissa, quick to include you with her opinion.
"Whatever." Kylie walks next to you and sits on the arm of the couch, facing the table. Her focus moves to her phone giving you and Larissa a few more minutes of deck planning, until Kylie asks, "So how do you play this anyway?"
"You actually want to know?" Larissa asks, surprised.
"Sure," Kylie states matter-of-factly, then slides her butt farther back onto the arm, straddling it with her legs which quickly tuck up under her to get over the cushions. Her hands strategically grip the bottom of her tank top, elbows locking and pressing her small tits together as she shifts much of her weight forward, planting both of her hands onto the arm of the couch. This downward stretch translates to her tank as well, the stretch of fabric deepening her cleavage and presenting a narrow strip of fair skin down the center of her chest.
"Okay..." Confusion fills Larissa's voice, but she won't turn down an opportunity to explain one of her favorite games. "We're trainers battling in the great Pokemon Arena, and the first person who..."
Larissa starts into a very thorough explanation of the lore, rules and mechanics of the game. You, like Larissa, are skeptical of Kylie's interest. But the exhibitionist teen is attentively staring directly at her younger sister, gently swaying back and forth as her sissy's words wash over her in a steady stream of information. You sit back and glance between the two siblings, patiently waiting for Larissa to finish up.
You catch Kylie glancing in your direction between your own glances. Perhaps her attention isn't as undivided as it seemed. It occurs to you after a few more minutes that Kylie's subtle swaying is becoming a bit more animated. Her legs buck underneath her ever so slightly with every backward motion. After another minute you realize that she is rolling her pelvis beneath her baggy tank. Is she grinding herself into the couch?
That thought brings your dick to life with speed. It starts to push down your pant leg forcing you to sit up in an attempt to cover yourself. Kylie notices your squirming and gives you a sly smile.
"Are you two even listening?"
You both look towards Larissa. It seems you weren't glancing at each other so much as gazing.
"Oh, come on Rissa," Kylie whines, her swaying halted. "There's too many rules. Do I need to know all of them?"
Larissa rolls her eyes. "Only if you want to play!"
"Hmmmm..." The teen pauses to add a few long slow dry humps against the couch, keeping eye contact with you the whole time. "Maybe not today."
You watch Kylie pull herself forward and off of the arm of the couch with a visible shiver. A shiver you share in your dick. But the state of the arm as Kylie steps away is what really holds your focus. A thin wet line adorns the top of the arm right where she was sitting. If there was any reasonable doubt as to what she was doing before, this nullifies it.
"I don't know why you asked then," Larissa replies frustrated.
"I don't want to have to think today," Kylie replies. "It's too hot to think. Aren't you hot sis?"
"Not really," she says, tugging on her nightie as if she wasn't sure.
"I know Riley is hot," Kylie winks in your direction. "I can tell just by looking at him."
"Well he's handsome," Larissa notes bluntly, almost startling herself by saying it. She stutters the rest of her sentence. "Uh, um, but..."
"I probably shouldn't have worn jeans again today," you offer, "but I'm not overheating or anything."
"You say that now," warns Kylie, "But in an hour or two I'm sure you'll be sweltering!" her words are soaked with drama, her hands fanning the front of her shirt displaying more and more cleavage. "If you two don't do something about it now you'll regret it later, I promise!"
"So... what should we do?" Larissa asks tentatively.
Kylie is all grins at this point. She keeps crossing her legs and rubbing her thighs together, pacing intermittently next to the table.
"Well Riley could take off his shirt or something," she suggests so casually. "But I don't think it's fair that we ask Ry to do that in our house... unless you joined him."
"How? You mean take off my nightie?!?" Larissa has a mild look of shock on her face, accompanied by a silly smirk.
"Duh! Seriously, where are your manners, Rissa?!" she adds, scolding her sister playfully. "What do you think about that, Ry?"
