Overnight Sisterly Lovin'

Sometimes, Kacey hates having a penis. She wishes she were just a girl, like her Mom or her nine-year-old little sister, Taylor, instead of a herm like her Mama. At eleven years old, just entering pubescence, she feels like her body is constantly buzzing with naughty feelings. Right now, lying in bed at 2:30am and unable to sleep because her little cock is fully erect, poking out of her panties and throbbing and oozing cum into her nightshirt, is one of those times she hates having a penis. It's so annoying, and she doesn't know how to make it stop.

Well, actually.

She knows one way to make it stop, temporarily.

But it's really naughty.

So she shouldn't, but if she doesn't she'll never get to sleep. She sighs. She lies in bed a couple minutes longer. Then she gives up. She shuffles out from under her covers and onto her paws. She grimaces at a new feeling between her legs. She reaches down into her panties to peel her fuzzy balls away from her wet spade, mouthing the word 'yuck'. Quietly, she pads over to her door, then carefully opens it to sneak to the next room.

A couple months ago, Kacey's moms made her move into her own room, saying that now she's eleven, she's gonna want her own space away from Taylor. She didn't like it then (and neither did Taylor) and she doesn't like it now. It's so much more effort to get to Taylor's bed now she's sleeping in a different bedroom.

As the wolf pup closes Taylor's door behind herself, Kacey considers her possible story if she's interrupted. She'll say she had a bad dream—a nightmare! And it was about Taylor. And when she woke up, she couldn't get back to sleep until she checked on her little sister. Yeah, that seems really good. Her tail wags. She turns her full attention to the other inhabitant of the room.

Taylor lies sprawled on her back with her tongue lolled out, covers kicked off and nightshirt already helpfully rucked up to her waist, exposing the lower-most pair of teats on her belly. Kacey grins at how cute and silly she looks, even asleep, and creeps onto the bed to get a better look.

Taylor looks a lot like Kacey, but smaller. They both have similar coat colors, a sort of rusty brown-grey, but whereas Kacey has a mask and green eyes, Taylor's face coloration has much more white and her eyes are striking blue. But Kacey's not looking nearly high enough to be thinking about Taylor's face right now. She's looking much lower.

Taylor's wearing her favorite panties, the pink ones with the happy clouds and rainbows. They're starting to wear out—the waistband has become a bit frayed, and Kacey knows there's a tear forming along the band on the left leg. She's really careful as she eases them down her little sister's thighs, because she doesn't want to damage her little sister's favorite pair of panties. That would be mean, and Kacey's a good big sister.

And there it is.

Taylor's pussy is Kacey's favorite thing in the whole world. Just like Kacey's, it's a canine spade, with soft y-shaped lips. It's a sort of darkish pink color just like Taylor's nipples. Kacey reaches a hand down to caress her cock while she kneels there between Taylor's legs.

She doesn't really know why she likes being naughty and looking at Taylor's pussy, or why it feels so much better then than other times, but she does like looking and it does feel better. She runs her hand up and down, feeling the different textures of her fur, her fingerpads. She bites her lip as she leans in to sniff her little sister's cookie, speeding up her hand.

It looks so good, and it smells so good, and—she wants to lick it. Kacey hasn't done that before. But now she wants to. Her tongue flicks out, swipes across it, feels the way it gives. Her hand rubs faster. It tastes good. Or maybe not good, but tasting it feels right. As she takes another careful, slow lick, the hand on her cock shifts to rub and caress her knot—another thing she doesn't know why but knows it does feel good. Her other hand snakes down below her balls to probe at her own spade.

That's right! To make herself feel good, Kacey puts her fingers inside her cookie. She leans further in, and presses her tongue against her sister's entrance, eases it inside. It's even better. And the more she does it, the wetter her little sister gets inside, and the better she tastes. And then— 

Kacey's breath hitches.

She's cumming. At last, the wonderful feeling of orgasm wells up within her, washes over her. Unconsciously, she pulls her faces away from Taylor's crotch to lean back and thrust her hips forward just as her mounting orgasm tenses up her balls and she fires her first squirt of semen.

It lands directly on Taylor's exposed, wet cookie.

The next shot fires long and wide, across Taylor's lowermost left nipple. Seeing her cum on her little sister does something to Kacey, and suddenly she finds herself leaning over the younger pup, squeezing her knot while she coaxes the rest of her ejaculate out directly onto Taylor's pussy. She grunts once, twice, as she spends herself, then falls back to sit on her heels, out of breath.

She doesn't know what came over her. This is the naughtiest thing she's ever done. Usually she just does her thing into her own hand or nightshirt, but tonight maybe she's gone too far. Taylor is a cummy mess. Her little cunny, already wet with her still-sleeping arousal and Kacey's spit, is coated in Kacey's thick white cum. A couple of wild shots and drips that landed on her thighs and belly catch the moonlight. There's even some in Taylor's favorite panties.

Kacey swallows thickly.

She slips her own panties down and off, then uses them to wipe off her cock and sop up the worst of her pussy juice, and tosses them to the floor. Then she lifts her shirt off and tries her best to wipe up Taylor. There's just so much of it. A lot more than usual. It leaves Taylor's fur stiff and mussed in a way that Kacey can't quite fix. 

Kacey gasps. 

Oh no, she's just smeared it into Taylor's pussy. There was so much of it, and her shirt wasn't doing enough to soak it up, and now it's inside her little sister. She tosses her gross shirt where she hopes her panties are, too, and leans in.

Okay, okay, she can fix this. Maybe she can lick it out! She goes to lay down between Taylor's legs but gets stopped by—Taylor's panties! They have cum on them, too! She yanks them down, maybe more forcefully than she should, and chucks them. She'll have to take care of them when she gets her own clothes. Then she lays down and sets to work.

It's on her third lap at the delicious cookie that something clicks in Kacey's mind.

She likes having fingers in her pussy when she plays with herself.

And she has both parts, a penis and a vagina.

And if those are both parts, and a cock is shaped kind of like fingers and feels good to be wrapped up, and a pussy is a hole that feels good to have something in it, then. 

Then.

Kacey wants to put her penis inside Taylor's spade.

It's already hardening again, poking from its sheath and leaving a wet spot in Taylor's sheet. She crawls up over the younger pup. Using one hand, she tugs Taylor's shirt up all the way to her underarms, exposing the rest of her nipples. Kacey leans down to kiss, then lick, each in turn. Taking a deep breath, she turns her attention to their crotches. So close to one another. She thinks she can feel the wet heat of Taylor's pussy. Her cock throbs, and drips a glob of precum down onto the bare spade.

Laying down atop her little sister, Kacey can't help the electric shiver as she feels all their nipples rub together—pushing her shirt up was a great idea. Then she lines up as best she can.

And eases the tip of her little cock into her sister's even littler pussy.

She has to fight not to moan, not to hump her whole cock right in, not to cry out. It feels indescribable. Her eleven-year-old vocabulary just doesn't have words powerful enough to adequately convey her pleasure. And she's only just gotten her tip in.

Slowly, ever so slowly, she pushes further and further, spreading the tight, virgin cunt of her little sister to accommodate her. And then their hips meet, and she's fully in.

She huffs.

She pulls her hips back a bit, feeling the cool night air on her cunt-moistened cock-flesh, then forces back in. It's still tight, and still a slow struggle, and still unbelievable. Out, then in. Slowly, she settles into a rhythm, gently humping her sleeping sister.

Soon, the combined arousal of two pussies has her little fluffy balls dripping into the bedsheet.

The soft rustle of fur against linen speeds up, her toeclaws digging into the bed. Her humps become a little more forceful, as Taylor's pussy loosens and her own eagerness drives her further.  And then, she makes a startling discovery—her inflating knot starts making it hard to get the base of her cock in and out. She pops it in again, then out, then back in, and then finds she can't tug it back out. Not that she'd want to. The way Taylor's lips clamp around the base of her knot, Kacey is exactly where she wants to be.

Her movements have to be more shallow, quicker, to accommodate for lessened mobility from their tie, but that's okay, she's close.  Nipples teasing across nipples, panting, tail lifting and muscles tensing as her balls draw up, Kacey realizes she miscalculated.

She hadn't considered what it would mean to be inside Taylor when she came. And now she's inside Taylor and about to cum.

She gasps.

And then it's too late to rethink, too late to reconsider, too late to pull out, too late to stop, too late, too late too late.

She cums.

Teeth bared, whimpering, twitching, clinging to her nine-year-old little sister, eleven-year-old Kacey cums. She cums and it's like nothing she's ever felt before. Previous orgasms felts like waves washing over her, but this is like becoming an entire ocean, washing over and into and through and out of herself. She feels her cock throb and jump and pump gush after gush after gush of her semen deep, deep inside Taylor's little cunny. She feels her own pussy clench so hard she squirts, hears it spatter onto the bedding, feels it drip from her clit and run down her still-tense balls. She feels every hair of her furry coat stand on end.

Kacey cries.

It feels so good so right so perfect that she cries. She wants this every day, every night, always. She lifts her head to tap her nose to Taylor's, press a soft kiss to the younger pup's lips as she dumps the last of her load inside her pussy.

And then she's so tired. She knows she should clean them up, put Taylor's clothes back on her, get back to her own room, but she's just so tired. And she's so comfortable. She feels like she's floating in a cloud, everything a pleasant hum.

Unaware of her own voice, she whispers “I love you” into Taylor's ear, then falls asleep.



Kacey startles awake right after sunrise to find herself still in Taylor's bed, but the covers are now over them, hiding their nudity and the wet evidence of her earlier activities. She's on her side spooning her little sister, hands resting over little nipples as the pup snores. They're tied (again? still? Kacey doesn't know), and—

She's cumming inside her little sister again.

She can hear Mom's pawsteps in the hall, and she's cumming inside her little sister again.

Mama's calling from the kitchen, and she's cumming inside her little sister again.

Mom's opening Taylor's door to wake them, and she's cumming inside her little sister again.

Somehow, blessedly, Taylor doesn't stir. Fighting hard not to give herself away, Kacey lifts her head and makes a shhh motion with her finger in front of her muzzle. Mom smiles, blows her a kiss, mouths the words “love you”, and backs out of Taylor's room. Kacey drops her head to the pillow.

She cums again. Or maybe that previous orgasm never finished, and picks back up from the relief, Kacey doesn't know. She ruts herself against the sleeping pup, pumping more and more into her until it overflows and puddles beneath them.

Running her hand up and down Taylor's soft front, squirting the last of her orgasm inside her, Kacey wishes to be able to do this, again and again and again, forever.
