Staying at Air Temple Island, one thing that little Jinora has learned about the Avatar is that she's a heavy sleeper.
Like, a heavy sleeper.
Jinora, for her part, is totally fine with this aspect of Korra, no matter how much it frustrates her father when Korra doesn't wake to his soft knocking at her door. Instead, it has become the kids’ job to get her up for training in the mornings, and they've taken to it with gusto—sneaking quietly into her room to suddenly jump on her chest or break into a choreographed set of leopard seal whale songs.
For the most part, Jinora hangs back during her siblings’ antics. Though if a sudden gust of indoor wind from her fingertips tugs off Korra's covers once or twice, no one needs to know.
Jinora knows that Korra is a heavy sleeper, unlikely to rise for anything, especially when tired after training. She wakes on her own schedule or none at all.
All this to say that, when Jinora finds Korra taking a “quick nap” on the couch or in her room, she has the almost uncontrollable urge to do something terrible. Her stomach coils with a strange heat, licking at her inner thighs and pulling her feet closer to the sleeping figure unbidden.
Jinora peels off Korra's pants carefully, pulling them to rest just beneath her taut ass. Her breath comes heavy and she pushes her face to the crook of Korra's hip, burying her nose into the skin beside her panties. Her eyes flick upwards, checking, once more, on Korra's even, sleeping breaths.
Jinora opens her mouth to press a gentle, if wet, open mouthed kiss to the sensitive skin there, feeling the muscle in Korra's thigh jump beneath her hand. Jinora holds back a chuckle. So sensitive.
Jinora cups Korra's covered cunt with a small hand, basking in the soft sigh that slips from Korra's mouth. She bites her lip, dragging her fingers softly over Korra's folds over top of the thin fabric. She takes her time just marveling at it, the crease of her underwear where it sits on her skin, holding onto the fat lips of Korra's pussy as she traces it.
Jinora presses a soft kiss to those lips—her very first kiss in fact, given to Korra's clothed, sleeping cunt—before running her hands gently up Korra's hips to reach the waistband of her panties and unwrap them from her pussy, the gusset sticking slightly to Korra's centre before coming off with a wet sound.
Jinora licks her lip, and barely resists stuffing her face into Korra's wet heat, nosing her way between her lips until those very juices of hers stick to her nose and chin. Instead, she carefully presses the flat of her tongue to Korra's swollen clit, lapping at it painfully slow as she catches Korra's juices from her centre on her tongue and drags them up to her sensitive bud. Korra tastes a little musky, slightly salty with sweat, but sweet like skin, and Jinora’s eyes nearly roll right back into her head, fingers twitching on Korra's thighs, playing staccato rhythms on the soft flesh.
Korra groans sleepily at the sensation, her hips stuttering just slightly on Jinora's tongue. Jinora would smirk if her mouth wasn't otherwise occupied. She presses one last wet, sucking kiss to Korra's clit, and crawls slowly up the Avatar's prone body, careful not to rest her weight on the older girl as she moves.
She stops when she reaches just below Korra's collarbone, their crotches lined up as Jinora's smaller stature still leaves her craning her head up to watch Korra's sleeping face, her breaths deep and even.
Jinora's hand slips once more to her pussy, this time enjoying the feeling of her naked skin on her palm, and grips her cunt tight, watching Korra's expression flutter and mouth fall slightly open at the punishing pressure of Jinora's little hand on her. She pats it a couple times with a hum, satisfied with Korra's sleeping reactions and scoops up the new slick pouring from Korra's pussy, fingers it back into her hole before pushing a single, searching digit inside. Korra's walls part easily for her, practically sucking her finger further in as Jinora explores the soft texture of her insides. Soon, a second finger follows the first and she gently scissors them open, testing her resistance.
Korra continues to lay slack, but her breathing quickens just a bit and the muscles of her abdomen pull taut, causing her hips to jump and pushing her cunt further onto Jinora's hand. She has to stifle a giggle, seeing the older girl fall apart beneath her tiny hands, unknowingly fucking herself down on a kid's digits.
Jinora quickly removes her fingers from Korra's searching, shivering heat, and hears Korra let out a moan that, under any other circumstances, would have easily been mistaken for a heady breath. Watching Korra's unconscious body search desperately for her touch molifies something in her, the small part of herself that would have kept her from ever experiencing Korra's skin and heat for herself like this. The part that even now, with Korra laid out and unwrapped beneath her, would deny her the pleasure of exploring Korra's firm, toned body.
Moral vigor renewed, seeing Korra's hips twitch towards her like she wants this—wants Jinora—a frown creasing her brows with a short whine. Jinora chuckles softly, teeth digging into her bottom lip to keep herself quiet, more concerned with alerting her family outside the room than the sleeping Avatar.
She takes the hand that was inside Korra, still wet with her arousal, and pushes it inside her own pants to fist at her little cock, shivering at the feeling of Korra's fluids on her member.
Jinora is young, and yet to grow into her cock. While she is certainly larger than her brother, she is loath to admit that it probably wouldn't even compare to the older boy ‘Mako’ that Korra has been so… infatuated with lately.
Jinora strips her cock quickly to the thought that, she is sure, no one's ever seen Korra, touched Korra, the way she has now, all pliant and needy and sleep-soft. Soon, she has to pinch the base of her dick to keep from coming too early, thinking of Korra waking, her eyes opening wide and surprised with Jinora's kid cock stuffed tightly inside her, painting her insides to mark her where no one else can reach.
Jinora's gaze jumps up to Korra's face repeatedly as she lines herself up with Korra's entrance, fear and arousal and temptation swirling in her gut and making her small cock stiffen even more.
Korra stays asleep, breaths finally evening out again since getting fingered open, relaxed and waiting for her like an easy whore.
Jinora can't wait to split her open, feel her insides squirm around and pull her deeper just as it did her fingers.
She presses the head of her weeping cock, covered in Korra's own juices, to her entrance, eyes kicking once more up to Korra's sleeping face. The feeling of wet flesh that meets and then parts for her has her groaning as she fails to muffle the sound in her chest, head dropping forward to hang from her shoulders as her skinny legs tremble above the older girl, barely holding herself up.
Jinora takes in a deep breath, holds it, and opens her eyes where they had squeezed closed to watch as her tiny cock pushes slowly inside Korra's now fluttering hole. The sight of them together, Jinora’s small hips fitting neatly between Korra’s parted legs, nearly twice the size of her own, slowly engulfing her tiny form, has her thighs quivering.
The heat that meets her skin is near heavenly, and she has to stop what feels like every couple millimetres to keep herself from coming or snapping up into her inviting warmth with abandon. She pauses nearly halfway in to catch her breath, ignoring the stars she feels encroaching her vision as her cock is practically pulled forward into that tight heat by Korra's fluttering walls, only for Korra's breath to hitch and her hips to grind down, impaling herself further onto Jinora's waiting cock in her sleep.
Korra's hips twitch constantly now, and Jinora sits and waits, wide eyed, as she watches Korra's movements push her further down the younger girl’s length. Jinora's toes curl into the couch cushions and she gives a tentative snap of her hips to fully sheath herself inside of her.
Korra just can't help herself, she moans in her sleep and rolls her hips into Jinora's where she's sat on her cock like she wants more, and Jinora wishes she was grown and could give it to her, can't wait to get tall and big and thick enough to fill her needy Avatar completely.
In the meantime, Jinora meets the sleepy, uncoordinated thrust of Korra's hips with her own, guiding them into a rhythm until they're simply rolling their hips together with Jinora's dick solidly seated inside Korra's wet and cloying heat.
Korra's mouth has gone slack and her breaths come with noise more often than not, occasionally interrupted by a light, hiccupped snore as her breath catches in her sleep.
Jinora shivers, pulling her hips back, out of their languid rhythm, to start thrusting into that tight, yet sleep-loose heat. She holds Korra's thighs apart so she can drive in harder, faster, nearly twitching at the overwhelm of all these new sensations.
She fucks Korra on her kid cock, hips slapping meatily in the still and quiet air, and can't help but let out a shirt, cut off moan of her own.
It feels so good inside her. So right. Jinora thinks she could stay surrounded by this heat forever, keep Korra bouncing on her dick, loose and unconscious, until she's old enough not to need the excuse of sleep.
She fucks her good, hard, chasing her own pleasure and release without a care to Korra's own, small body shivering atop the older girl’s.
Jinora’ll train her nice and good, she decides, until Korra's body craves her tiny kid cock and only hers. She realizes in this moment that she'll never be able to let go of her. Korra's so good like this, so loose, so pliant, the perfect little fucktoy hole to hold her cock.
Jinora whines behind her teeth, long and low, and comes as deep in Korra's cunt as she can manage, shooting her spunk up Korra's twitching, shivering walls. At this, Korra’s breath catches, eyes roving beneath her lids as she arches her back, lifting her hips up off the couch and Jinora with them. Jinora feels another spurt of come shoot out of her dick at the display of strength as she scrabbles for purchase along Korra's torso, lifting her little body up and into the air before crashing down with her.
Jinora snuggles into Korra's arms, pushing her face into her ample chest.
Later, Korra will wake and remove herself, awkwardly, from Jinora and quietly pad out of the room, but not before brushing an affectionate hand through her hair and marveling at the sated look on her slack face.
Korra will find that Jinora joins her afternoon naps more often, and wonder if this is what it would be like to have a little sister—if Jinora, the oldest of three, is looking to her to make an older sibling of sorts. Korra will let her have her moment, and meet affection with affection as she buries something tight in her chest deep within her.
If sometimes, Jinora’s leg slips between her thighs, grinding, and lets Korra ride it in her sleep—and if Korra sometimes wakes to her hips sleepily gyrating over Jinora's smaller body after a really good dream—then what the other doesn't know can't very well hurt them, can it?
Jinora has trained Korra's body to react to hers by then, and revels sadistically in the guilt she sees wash over Korra every time the sight of Jinora or her innocent hands on her causes heat to gather low in her belly and slick her underwear.
Jinora doesn't allow it to put distance between them, instead egging on the older girl’s arousal with an increasing flurry of innocent touches or sleepy embraces.
Korra says they're all ‘like family' to her, and Jinora delights in calling her Sis when she wakes up with her thigh propped between Korra's own and her chin resting on her chest, watching with sick satisfaction the blush that takes over Korra's face at the word.
Korra might not know it yet, but her body sure understands the kind of relationship Jinora's been cultivating between them, if the stutter of Korra's hips into Jinora's leg says anything about it.
Jinora tightens her arms around Korra's waist, grinning impishly up at the older girl.
“What's up leaflet? Training tire you out again?” Korra asks, willing away the anchor sinking guilt in her gut.
“Only as much as yours,” Jinora replies cheekily, subtly nuzzling her cheek into the soft mound of Korra's breast. She can hear Korra's breath hitch, and wonders what kind of sight she makes to her—a sweet little thing all spread out on top of a woman whose core slicks at the most innocent of her touches. She tucks her face into Korra's skin to hide the smile that splits her face at the thought, lifting her hips up just enough that Korra won't feel her half chub against her thigh.
They've got time, Jinora knows, time until Jinora can fuck her properly, indulge in the kind of lovemaking her parents get up to and pop out a couple kids of their own. But until then, she'll bask in just this—her secret and the way Korra glances at her when she thinks she's not looking.
Jinora snuggles in closer. They've got plenty of time.
