Kay nods at something over Winter's shoulder. So Summer makes her presence known, walking fully into the tent and kneeling next to her sister.
"Oh schhh-- frick," Winter huffs with the unpleasant surprise.
"You really feel that way?"
"How long have you been here? Freaking snoop!"
"Winter..." Summer brushes the hair from her face and sighs. "I knew you were kinda obsessed with her, but... I didn't --"
Winter slaps her hand away. "What are you even doing here? Creep! Trying to spy on me?"
"I wasn't here to spy on you. Deflate your head a little, huh?"
"Then what?"
"I'm here to get buttfucked by Kaykay."
Kay snorts. "Someone's an eager beaver. That's your sister you're talking to, you know." She glances at Winter. "Well, now you have an answer. Tell Wes how you feel or Summer's gonna blab. And you know she's definitely gonna blab."
"Whatever. Freaking losers." She stands. She stomps and makes a face at Summer. "Have fun taking it up the ass, weirdo. I hope you can't walk straight for a week."
"Me too."
Winter shudders in disgust, or at least pretends to. She hasn't even stepped out of the tent before Summer is wrapping herself around Kay and pulling her into a lascivious tongue kiss. Kay's just as much of an eager beaver, and returns it.
Maybe it's the noise of smacking lips or maybe it's just the persistent mental image of Summer taking it up the ass -- either way, Winter stops, turns back around, and says: "can... can I watch?"
Summer's arms are still looped around Kay's neck. She glares at Winter. "Really? And you call me a creep."
"I just... want to know what kind of gross stuff Wes likes the best."
"Honey," Kay begins, "the key to Wesley's heart isn't through sex--"
"Yes it is," Summer cuts in. Kay frowns at her. Summer pulls back just a little, arms still around Kay. "What? It totally is! Sex is all Wes can think about!"
"Do you really want your own sister watching this?" Kay says.
"Depends. You okay with my weird little sister watching us go at it?"
Kay shifts so that she's nose-to-nose with Summer. Their brows are touching. "All right. But we're gonna do this my way. I want this to be educational for Winter."
"You been drinking, Kaykay?"
"Only reason I'm agreeing to this," she says with a hiccup.
---
A few moments later, all three girls are naked. It feels so nice and refreshing to be out of those stuffy clothes that they went fishing in. Summer rubs the underside of her tits to mop out the sweat trapped there. Winter massages her own sore soles. Kay fans herself. And when they're all as comfortable again as they're going to get:
"All right," Kay tells Summer. "On your back."
"Yes ma'am." She lies on a row of pillows laid out for the purpose.
"Hold your knees apart."
"Yes ma'am." Following the orders of such a mean bitch is exciting as hell. She hikes her legs up. Gets her wrists under her knees and spreads them.
"Get a little closer," Kay tells Winter. "Don't be shy. You wanted to watch."
Winter scoots forward on her knees. She stares intently at her older sister's genitals. It's the first time she's had such an up-close and personal, clear and unobstructed view. "Whoa," is all she can muster.
Summer's pussy lips drift apart from the way she holds her legs akimbo. It's reminiscent of clingfilm being peeled from a smooth surface. Her asshole is completely visible too, dark and puckered, winking. Her skin is evenly hued -- bronze all over. Her cherry-red nails dig into her thighs where she holds herself. Showing off like this, even to her own sister, gets her all wet -- wetter than she already was from a daylong sweat and her pre-sex anticipation. Her pussy starts creaming up.
"I'm sure you've seen pussies before," Kay says. "Maybe you've already looked at yourself in a hand mirror, or maybe you've seen a lot of porn. And if you've been having sex with Wes, you definitely saw hers. But take a second here to really learn the shape of a girl's cunt, Winter... see?" Kay indicates the different anatomical landmarks with a finger. "This is where a girl's clit hides... and these lips, even for a girl with an innie like Summer here, are bright pink on the inside, see?" She drags one of Summer's labia to the side to demonstrate its interior. "The entire thing is squishy -- so, so squishy... see that? Your fingers sink down in a mound like this. Try it."
"Kay--" Summer yelps.
"Wow..." Winter presses a forefinger testingly down on Summer's mound. The touch isn't very close to Summer's cunt-hole but Summer gasps all the same, so Winter draws her hand back. Yet her face stays so close that Summer can feel her hot breath on her holes.
Kay continues, petting Summer's cunt to keep the girl docile. "A girl's vagina is lower than you might think... here's Summer's, for instance." Winter nods along as Kay shows her. "And even further back..." she puts her fingertip to Summer's sweaty asshole. "A girl's butt." She twists a finger teasingly around the circumference. "Here's some life advice, Winter. Some girls are really into anal. The others haven't found out yet that they're into it too." She slips the finger partly in. Summer's whole body flinches and she lets out a little "ah" of pain.
Winter sits on her butt with her heels on the ground and glances down at herself, down in between her own legs. She seems to be comparing. Considering herself. She runs a hand back and forth over her brown pussy. She even takes a hesitating feel at her own asshole.
"What do you think Wes likes best about having sex with you?" Kay asks Summer.
"Hmm... she likes the way I cum."
"You would say that." Kay gives Winter a sly look. "Wes has an even simpler mind than that. She just likes to play with a girl's holes." She cups Summer's pussy with a palm. "Wes likes getting eaten, too. I should know... I've heard those two going at it more than enough..."
"Do you like eating pussy?" Winter asks.
"Oh, it's the best," Kay says. She brings her face down and gives Summer's juicy twat a theatrical kiss. She makes sure to mold her lips to the shape of Summer's fat cunt, to smack the skin there and make sucking, suckling noises. She even moves her jaw as if she's chewing. It's like biting into a peach. And just like biting into a peach, she sucks out all the nectar. That alone makes Kay moan in pleasure and her eyes roll back. But this was only a prelude. She pulls away, chin shiny, and says: "Wes is way grosser than that, though, isn't she? So she likes eating something else."
"Wh... what's that?" Winter stammers.
"This hole right here." Kay purses her lips, and this time she dines on Summer's tight ass.
"Kay... oh, Kay..." Summer pants, turning her head side to side.
As before, Kay makes the noises extra loud and extra lewd for Winter's benefit. She eats Summer's ass with an almost frenzied gusto, her pale hands pressing down on either of Summer's legs to help keep her spread as wide as possible. Summer's cunt cream runs down Kay's face and smears her glasses. And Kay's drool runs down the crack of Summer's ass as it drips onto the pillows below.
"Can I touch myself?" Winter asks.
"Of course," Kay replies.
Winter starts to masturbate while she watches her older sister getting rimmed. "Does Wes do this for you, too, Summer?"
Summer nods. "Uh huh. She *loves* eating my butt."
"Wow... oh, wow..."
Kay pulls back and gives Summer's ass a love tap. "Now you try."
Summer's eyes go wide. "Kay -- wait, no--"
But Winter shows no such hesitation. She dives right in, and gets her tongue right up inside her sister's ass.
"Uhhh-hhhh-hhh," Summer groans, shivering. It's so good and so nasty, both at once.
Winter looks up at her from between her spongy ass cheeks. "You said you wanted to give my mouth a try sometime. Now's the time."
Kay pets Winter. "You should eat both holes, though... hmm. Here." With that, she crawls behind Winter and spreads Winter's ass wide apart. "How about you try to mimic me, all right? Move your tongue the way I move mine."
Winter grunts as Kay buries her face in her backside. This is such a weird, slimy, alien sensation. And embarrassing. She doesn't feel clean after being out in the sun all day, but Kay obviously doesn't care. Which, on second thought, makes sense... after all, Summer's cunt and ass are equally dirty, equally stinking of sweat and grime, but that stink is intoxicating, heavenly... there's something about an unwashed pussy that's just divine, and she can't get enough. So when Winter looks over her shoulder at the way Kay is pigging out with glasses pushed up and her nose up her ass, it makes Winter feel... happy. Proud. Sexy.
"Hey! Don't watch me," Kay says, giving Winter a playful swat. "Feel me. Feel my tongue and try to do the same thing to Summer."
Winter gets back to work. This time she intently focuses on mirroring every one of Kay's motions. When Kay puts a tongue up her ass, she puts her tongue up Summer's ass. When Kay licks out her twat, she licks out Summer's twat. When Kay sucks her clit, she sucks Summer's clit. It really is an educational experience. She's learning the perfect way to coax orgasms out of dyke twat by having orgasms coaxed out of hers.
Summer runs a hand through her hair. Any reservations she had about incest are well and truly dead. "God, Winter, that's so good. You eat my ass so good." She bucks her hips. "You better get used to this, cause I'm gonna have you in my bed every night... my ass is gonna be your pillow from now on... you hear me, bitch?"
Winter's only answer is to tongue-fuck her deeper up her clamping pussy.
As Summer crosses the brink, Kay crawls forward to watch it happen. Gently, but firmly, she puts a hand on the nape of Winter's neck to keep her held in place. She grins up at Summer.
"I'm gonna come in her mouth, babe," Summer says. Her voice is light and airy, bimboish. "Wanna see?"
Kay nods.
"Ooooooh fuck," Summer sighs in orgasm. Kay helps it along by rubbing the clit for her. With Kay frigging her love-button and Winter's hungry mouth sucking her slut-hole, Summer has a spectacular cum.
"Make sure to drink it all," Kay instructs. "Wes likes a girl who swallows..." So Winter drinks, neck undulating as she swallows all the cum that Summer pisses down her throat.
When Summer's orgasm subsides and Winter pulls off with a loud "pwah," both sisters are gasping for air.
"Damn, babe," Summer heaves. She smiles at Kay. "You really put my sister to work. Thanks."
"Just keeping the non-pants-wearers in line," Kay says. She lies back and adopts the same pose Summer had: legs hiked, spread-eagled. "Now you two do me."
The Denali sisters attack Kay's fuckholes with glee. Summer licks Kay's cunt and Winter licks her ass. Kay lies there with a dopey smile and enjoys not one but two young mouths sucking her off. If only Wes were here to sit on her face, it would be perfect.
That daydream gets cut short, though, as Summer whispers to her sister: "Hey... you wanna know something else Wes likes to do?"
Kay doesn't know what's going on as Summer and Winter grab either of her arms. They haul them up, above Kay's head, while meanwhile wrapping their legs around each one of Kay's legs to keep her pinned. "What the hell are you two doing?" she demands.
"Wes's got a thing for armpits..." Summer explains. "She never told you?"
"WHAT?" Kay shouts.
Summer giggles. "Wow, Kaykay... these things are pretty rank. Is this where Wes gets her habit of forgetting deodorant?"
"Oh my g-- I don't like putting carcinogens under my arms!" Kay says. "Going all-natural is-- ghh--" she chokes and flinches, thought derailed, as Summer puts her lips and nose to the basin of her armpit.
"Don't listen to her," Winter whispers in Kay's other ear. "I think you smell really good. Even here... see?" She copies her sister and starts to eat Kay's armpit like it's a pussy. The same moves Kay taught her for pleasing a drippy cunt, she puts to use on Kay's drippy pit. In Kay's current pose, the tendons at front and rear make the bowl-like shape of her armpits seem impossibly deep. Sweat still pools there, salty and acrid.
Kay, more from being held down than having her armpits licked, starts to have a miniature panic attack. But the Denali sisters have it under control. They reach down in tandem and stroke Kay's pussy until she calms. And as they start to finger her, she finally gets into it. Her eyelids droop shut as she surrenders to these dirty feelings.
"Summer, is it true...?" Kay asks weakly. "Wes... likes putting her face in your armpits...?"
Summer nods, tongue raking the still-perspiring gooseflesh.
So Wes really does take after Noelle. Kay cums on the two sisters' hands while reflecting on that, dreamily thinking how much she would absolutely love to have, instead of Summer and Winter -- Noelle and Wesley eating out her armpits and playing together inside her pussy.
She intends to make it happen. Sooner rather than later.
