Help Me Big Sister!
"Sissy! Sis, wake up!" came a feminine whine. Yawni blinked open her bleary eyes and saw her sister's feline face looking down at her. She could tell Lilly was in some sort of discomfort from the way the younger femme switched her weight from one foot to the other and squirmed. The tip of her tail twitching slightly.
"Wh-what is it, Lilly?" She asked, trying not to sound grumpy. Yawni rubbed her eyes and slowly sat up in bed, trying to hold off another yawn while she waited for her sister's explanation.
"I...I'm in heat." Lilly wimpered. Her older sister held back a chuckle at how embarassed her little sister looked.
"You want me to make it better, like last time?" Yawni cooed, wrapping her arms around her sister's waist and pulling the femme into her lap.
It was hard to tell where one ended and the other began; both girls were nude, and their fur white with black patches here and there. Yawni had a spot that covered her right eye and left ear, while Lilly had just the opposite. Such similar markings made them often get mistaken for twins, though Lilly was a few years younger.
"P-please, big sister." She said timidly, as Yawni pulled her younger sibling closer and nuzzled into her hair. As she took a deep breath, the scent of her sister's arousal became clear.
The older of the two gently placed her sister on the bed. Both of them looked to be highschoolers, though Lilly appeared to be a freshman. She was somewhat shorter than Yawni, with a petite build. Her older sister was tall, with runner's legs and a slim form.
"Mmm, It's okay, Lilly. Your big sister is here to help." She gently brushed a bit of dark hair from Lilly's face before kneeling beside the bed. Her soft, pink, padded handpaws rested on her younger sister's hips, pulling her towards the end of the bed. Yawni licked over her little sister's navel, getting a tiny mewl of need.
"Ah! D-don't tease." Lilly begged her.
Yawni's breath quickened as the scent of her younger sister's heat-induced arousal began to moisten her sex. Hearing Lilly beg so needily, she parted the other femme's thighs and slowly licked across Lilly's dripping slit. Her little sister let out a gasp as her older sibling's rough feline tongue lapped over her clit.
"Ah!! Sissy..."
Yawni parted her sibling's sex, spreading the feminine lips open and exposing the slick, pink, flesh beneath with one hand. She could feel her little sister's thighs clench as cold air caressed her exposed pussy.
Lilly's hands curled as the need seemed to increase. She looked down at her sister, slightly suprised to see Yawni staring back up at her. Lilly watched as her older sibling's tongue lazily lapped up the feminine juice threatening to leak down her thighs.
There was something forbidden about watching her, and it only made Lilly more wanton.
Yawni's tongue wriggled into Lilly's tight feminine channel, making the younger femme squirm on the bed. Each lick brought forth moans and wimpers that couldn't quite mask the lewd sounds of Yawni pleasuring her sister. The elder of the two licked her lips and pulled her mouth away from her sister's pussy.
"Ah...Please don't stop!"
She ignored her younger sister's pleas, her eyes narrowing preditorily. It was time she had a bit of fun with her younger sibling. "Mmm, I bet all the boys in school like those." She murmured, straddling Lilly's hips. Yawni put her handpaws on her sisters breasts, squeezing lightly. "They've gotten really big." She couldn't hide her smirk as her sister's ears flushed pink.
Lilly tried to hide her face, embarassed by what Yawni was saying.
"You know, Lilly, you're coming to me so often these days. I'm starting to wonder if you're in heat, or just a little Nympho." This time her little sister wimpered and protested.
"N-no, I really am!"
"Suuure" Said yawni mockly, squeezing one of her little sister's tender nipples. Lilly arched her back and sucked in a sharp breath through her clenched teeth. "Oh, the little nympho kitty likes that, eh?" Yawni said as she began to knead her sibling's breasts, teasing both of the supple pink peaks of feminine flesh.
Yawni could feel her own hot, slick pussy ache with arousal. She lazily rolled her hips, pressing her slit against her sisters. Lilly's hips bucked before meeting Yawni's eagerly. The elder of the two leaned down and took one of the younger femme's nipples between her teeth, suckling lightly and bathing it with her rough feline tongue.
"Ooh...Yawni..." Moaned Lilly, licking her lips and looking at her sister with a lust-drunk, half-lidded gaze. Grinding against each other slowly, the young femmes both moaned in ecstacy as their hot feminine sexes rubbed against one another. Lilly was quickly being overwhelmed by the sensations of her big sister's hot, wet mouth on her breasts.
"Admit it..." Yawni said as she released the younger feline's breast with a moist pop.
"Nng..." Lilly clenched her eyes, pressing needily against her sister. "A-admit what?"
"Admit you're not in heat, and that you're just a horny little Nympho." The older feline purred, slipping her hand between where both their slits met. She teased her own clit, coating her fingers in her hot feminine juices.
"Wha? No!" Lilly protested, wriggling needily.
Yawni slowly licked her sticky digits clean, looking down at her sister domineeringly. "If you don't, I wont be able to give my horny little sister what she needs." She lapped over her fingers again, suckling them suggestively while straddling her sibling's hips.
The younger femme looked up at her sister, the inside of her ears a bright embarassed pink. "I a..admit it.." Lilly said softly.
Her big sister laughed. "What was that?"
"I admit it." Lilly said, a little louder.
"Admit what?" Yawni cooed condescendingly.
"That I'm a horny little Nympho.." Lilly's eyes darted away from her sister's.
"Say it louder!" Yawni commanded, eliciting a suprised squeak from her little sister.
"I admit I'm a horny little Nympho!" Lilly shouted before covering her mouth and gasping.
The older of the two didn't hesitate, driving two slick digits into her sister's hot, tight depths. She pumped her fingers vigerously in and out of Lilly, causing the petite femme to squeal.
"Ohh! Yesss!" Lilly cried out.
Yawni fingered her sister's feminine sex, juices dripping down her long, dexterous digits. She could feel Lilly's pussy suckling greedily on her fingers.
"Mmm yeah, you like that sis?"
Lilly nodded, her back arching in pleasure as she looked up at her older sister. Yawni grinned devilishly. "Then you'll love this." The younger femme gasped sharpley as she felt her big sister's finger press against her tailhole. It slipped in easily, well lubricated from Lilly's sexual juices.
"Ah...Ah...N-no..." The petite feline tried to protest, writhing on the bed. Yawni wiggled her finger deeper inside her little sister's tailhole, causing Lilly to moan lewdly, her hips bucking wildly.
Each pump of Yawni's fingers into the femme's aching pussy and tailhole was met with the moist squelch of her little sister's soaked cunt. "Cum for me, little Sis." She cooed, quickening her pace.
Lilly was brought to a shuddering orgasm, feminine juices drenching Yawni's hand and dripping down the younger feline's thighs. "Sissy!!!" She wimpered, as her thighs clenched tightly.
She waited for her little sister to stop writhing before slowly withdrawing her fingers and licked them clean of her siblings juices. Yawni leaned over Lilly and kissed her tenderly, her tongue snaking out to lick over the younger femme's lips. "I love you."
The taste of her own feminine juices mingled with the taste of her sister's mouth and Lilly leaned up to hungrily kiss Yawni back. Her arms went around her older sister's neck as she deepened the kiss, their tongues swirling around one another's. Lilly moaned into the kiss as their naked bodies became entangled on the bed.
"Mmm...Oh, sis...I love you too." The petite feline moaned as one hand fell downward to affectionately stroke her older sister's side. Yawni grabbed her little sister's hand and guided it down to her own aching feminine sex.
Lilly hesitantly began to rub her sister's pussy, running her fingers through the moist feminine folds. Yawni continued to kiss her passionately, nibbling and suckling on the younger femme's bottom lip inbetween aroused moans.
"Mrow..more!" Lilly's big sister purred, rolling her hips.
She complied, slipping a finger inside her older sister's tight cunt. So hot and so wet, Yawni immedeately bucked her hips with need. Lilly slipped a second finger inside her big sister, curling her digits slightly. As her fingertips caressed over Yawni's g-spot, the older feline trembled with need.
"Ahh...Faster...Please, little sister." Her big sister panted in Lilly's ear, her breath hot and heavy against the tender skin there.
Lilly began to push her fingers deeper inside Yawni, wriggling them around inside her.
"Oh yes...Oh little sis..."
Her older sister caught her lips once more in a hungry kiss, their tongues dancing and lapping against one another's. Yawni gripped her little sister's hips as Lilly began to pump her fingers in and out of the older femme's pussy. Each thrust of her fingers was bringing Yawni closer.
"Ahh, More...more, please, Lilly!" She cried, her hips thrusting forward against her little sister's fingers. Lilly slipped a third finger into Yawni's tight, wet sex, filling her older sister.
"Ah...s-so good." Yawni clenched her eyes shut as she came, hot feminine juices squirting from her pussy all over the bed "Nng...ahh...ah. Ah..." Lilly's older sister panted, holding her close.
As Yawni finally relaxed, she grabbed her little sister and gently pulled the sticky digits from her sex. "Mmm...now be a good little sister and clean up." She said softly. Lilly raised her fingers to her mouth and started to lick them clean, her eyes lulling shut.
"Mmm..." Yawni pulled Lilly close, snuggling her sister lovingly.
Both were exhausted, but Lilly's meek voice could just barely be heard behind the cum-drenched fingers she suckled upon. "I love you too, big sister."
Both femmes drifted to sleep and never heard the click of their bedroom door being shut as their father returned to bed.
