Slipping from beneath the covers, she darted across the room and plopped onto Nan's bed.
"But I've never seen another girl do it before. Can I watch?"
Nan was about to reply that it was too late, that she had already finished.
But Shari's eagerness changed her mind. Little sisters were a real pain most of the time, but Nan was just beginning to discover how much fun it was to be watched. And at least Shari could be counted on not to go blabbing to everybody.
"Well," she said with almost no hesitation at all, "okay. You've seen so much already, I guess a little more wouldn't hurt. But only because I happen to be in the mood anyway."
Her hands were already sliding down once more, dipping between her spread thighs.
Shari gazed at the spectacle of her sister's cunt. She'd never really gotten a good look at a woman's pussy before, and the sight of Nan's drooling pink cunt crevice held her spellbound while the girl fingers pried her slick, moist pussylips apart to display herself entirely.
"Well, you don't have to stare like that!" Nan made her tone scolding despite the fact that her sister's gaze was turning her on more than ever. "After all, you have a cunt too. It isn't my fault if you never use it for anything!"
"I do so!" Shari flared at that, her curiosity mingling with a trace of anger. "I'm not a child, you know. I know lots about cunts. And I'll bet I can show you!"
She'd hardly heard these words when one of her hands shot out, fingers entwining in her sister's rich pussy mound, her palm covering Nan's slick, gaping cunt slit.
Nan gasped at the unexpected maneuver. A surprising burst of fresh pussy juice geysered from her cunt at the intimate touch, and she couldn't seem to make herself push Shari's hand away.
Smiling at her big sister's reaction, the girl began to move her hand in a massaging motion, pressing the heel of her palm hard against Nan's stiff clit. "You see? I told you I know a lot about cunts. I know just what feels the nicest…"
"Mmmmmm," Nan groaned in pleasure, twitching up in automatic response. "Ohh, that does feel nice! It – ahh! – it's even better than when I do it oh, yeah!"
Shari increased the intensity of her massage, feeling her own pussy begin to gush. She'd never done anything like this before, and, obviously, neither had Nan. But oddly, the sensation of feeling another girl's pussy excited her. As she quickened her rubbing, one finger slipped up and began to work itself between her sister's puffy cuntlips.
Nan's eyes popped wide as she felt her cunthole luxuriously invaded. "Oh, what're you doing? It feels so delicious, don't stop."
"Don't worry." Shari watched as her finger vanished into Nan's pussy slit. "I know exactly what I'm doing. This is the part I always like best – having my clit rubbed while I'm fingering myself. Do you like how I'm doing it?"
Her finger began to move in and out like a little prick, and Shari almost laughed at that image. It was as if she was fucking her own sister!
"Yesss," Nan murmured as she arched up, succumbing completely to the massage. "Yes, that's just right! Now a little faster, push on my clit harder and get another finger inside me… that's it… ahhhh!"
Following directions, Shari wedged a second finger up her sister's cunt and began to fuck them both in and out with growing friction. Pussy cream burst all over her hand, and when Shari spoke, her voice was husky with newly discovered lust.
"I can do other things, too, things a girl can't do by herself. I'll show you."
Suddenly she bent forward on her knees, her mouth coming down to cover one of Nan's taut nippled tits.
"Oh!" The older girl arched up as Shari began to lick and suck her tender nipple, making it spire up even stiffer as her hand continued to fuck her sister's cunt.
Vaguely, Nan knew she should put a stop to what was happening. It wasn't right for two women – especially sisters – to be doing this kind of thing, no matter how good it felt.
However, by this time, any trace of will power had long since disappeared, and the words that poured from her mouth were exactly opposite what they should have been.
"That's it! Oh, that feels great! Suck on my tit, take it between your teeth and nibble on it – oh, yes, Shari, put your fingers all the way in me, harder, harder, make me come!"
Reeling up, Nan felt her cunt gush cream over her sister's hand in a horny blast of climax. The teenager's small, eager fingers were fucking in and out of Nan's pussy with moist, slurping sounds, driving her to complete orgasm.
"Ahhhhh!" she cried out, hunching on Shari's hand and undulating blissfully in the peak of her second climax of the morning.
At last, when Shari could feel the last tremors of her sister's body subsiding, she pulled back her wet hand and released Nan's tit with a grin. "See? I know just how cunts like to be played with. You're not the only one who knows how to have fun!"
Nan smiled weakly, gladly admitting her sister's expertise. "Uh, that was good. And I really wanted it, too. In fact… there's something even better than using your fingers. It might be more fun if you used your tongue instead."
For a moment, Shari's eyes went wide with surprise at her sister's suggestion. She'd never even imagined herself wanting to eat another girl's cunt out. But, by this time, the two girls had reached such a horny pitch that she couldn't help wondering what a pussy tasted like. Strangely, the notion was more exciting than ever.
"Goon," Nan urged, succumbing entirely to the need spreading through her. She creamed in a giddy flush of hot pussy juice at the interest in her sister's eyes. "You wanted to find out about everything, didn't you? Here's your chance. Try it just a little, to see what it's like."
"Well, okay." Shari gave in with a shrug and scooted down between her sister's legs. "I guess a little bit wouldn't hurt."
She paused a moment, taking an inquisitive look at Nan's oozing cunt. Her pussy was beautiful, its wet, pink lips looser than hers and flared apart, spilling slick cunt cream from a gaping pussy and letting the cunt juice leak in a slippery trail down her slit to the tight little pit of her asshole.
Shari would have stared longer, just admiring her sister's pussy, but the hunger growing in her own cunt was too much to bear. Her head ducked, and her tongue flicked out tentatively.
Nan gasped, stretching her legs as wide as she could as the girl's tongue stroked up and down her pussy, collecting the horny cunt juice that erupted from her pussy hole. "Ohh! Oh, that's good, keep doing that… ahhmm!"
She groaned and hunched up, grinding her cunt to her sister's face.
Shari lapped lightly over the length of. Nan's gushing cunt, for the first time in her life tasting real woman's pussy cream and probing for more. By now, her own juice-bloated cunt was aching with arousal, and that only made her attack Nan's pussy harder than ever. She dug her tongue wildly in and out of the dank cunt hole spread before her, working her tongue up to briefly strum Nan's erect clit and then back down over her puffy cuntlips, closing her lips over each of them in turn and sucking hard, until the older girl was twitching and moaning in pure delight.
"Oh, fuck, that's so good! Oh, Shari, what're you – ohhhhhhh!"
Her moans grew to a surprised pitch as Shari tongued her way down her sister's slit until she reached the small bud of Nan's asshole. Her wet tongue slid over its entrance with tantalizing curiosity and began to worm its tip in, sliding past Nan's taut ass muscles, digging deep.
Taken unawares, Nan creamed in a joyful burst of pleasure at this totally unexpected treat. "Oh, Shari, you're eating my asshole! Don't stop! It feels so good I can't stand it, eat me, eat my ass out – yeah!"
Lurching her hips off the bed, she cooed in whimpering abandon as Shari's tongue stroked in and out of her asshole, reaming her ass out frantically.
