"Oh Jesus, Kelly! Would you look at the size of that fuckers cock!"
Horny Marie Wallace spread her legs on the bed, staring open mouthed at the centerfold picture. She brushed the long black hair out of her eyes and furtively squeezed her plump tit through the blouse top.
"God, it must be eight inches long," she continued wantonly. "I wish they didn't have those fucking laws that make him pose with a floppy cock. Fuck, I wish I could see him hard! What a big, stiff, fucking dick!"
"Marie, you are so disgusting!" Kelly squealed. "Where did you learn to say words like that? You are the horniest little slut, I swear!"
The two teenage sisters were in Kelly's upstairs bedroom with the copy of Playgirl spread out on the bed before them. Kelly was beginning to regret that she'd allowed her baby sister to look at her secret collection of dirty magazines. A blush colored her cheeks as she watched Marie look at them. It embarrassed her that her kid sister now knew how much she liked to jack off.
Besides, she'd had no idea that Marie would react so violently. It was like she'd never seen a picture of a naked cock before. The little girl's eyes were glazed with passion, and she squirmed her ass repeatedly on the bed as she admired the stud in the centerfold. It was as if she'd forgotten that Kelly was even there.
She looked so horny that Kelly wondered if her baby sister would start playing with herself. The whole thing made her nervous. She liked to finger fuck too, but Kelly felt she had more control. She wasn't just sex-starved like Marie was.
She was only a year older, but Kelly felt like a completely different, more mature person. Her appearance was different. While Marie was slim, petite and dark, she was taller and extremely voluptuous, with an enormous pair of oversized tits. Kelly liked the way boys stared at her swinging D-cuppers when she walked down the halls in high school, but it bothered her when they shouted obscene things at her. She wasn't that kind of girl.
Her hair was short and blonde, cunt in a pageboy that framed her wide-eyed, freckle dotted face. Kelly was pretty sure she'd be elected homecoming queen when she became a senior next school year, and she'd had her fair share of dates. She was still a virgin, though. She'd never allowed a horny boy to do any more than finger fuck her pussy a little. She wanted to save her cherry for the man she married.
At least she was allowed to date. Kelly sometimes felt sorry for Marie when she considered her younger sister's predicament. Two years before, Marie had been so wild that she'd gotten herself raped by a gang of rowdies. Ever since, her parents had put sharp restrictions on her behavior. Marie was grounded almost every night.
"Oh, fuck, this is making me horny!" Marie whimpered, squirming all over the bed. "God, why didn't you tell me you had these fantastic pictures sooner?"
"Well, I almost wish I hadn't! You're certainly acting crazy, Marie!"
"Hey, Kelly! Do you think Daddy has a dick as big as this?"
Kelly felt her cheeks flush scarlet with embarrassment. "Marie! What a disgusting thing to say!"
"Well, do you?" Marie's eyes shone with shameless lust. "I've seen the bulge of it in his pants. It looks pretty good to me! I'll bet his cock's a real whopper!"
"Marie!"
"Or maybe Uncle Bill's got a big one, or Hank," Marie continued, respectively naming the uncle and their older brother who shared the house with them, along with their father, Mitchell, and mother, Betty. "Have you ever seen Daddy's cock, Kelly? You know, when he was coming out of the shower or something? Does he have a big one? Did it get nice and stiff when you looked at it?"
"Marie, this is absolutely disgusting!" Kelly spat. "Now you shut your filthy mouth or I'm going to throw you out of this room!"
Marie shrugged and returned her attention to the centerfold. She hadn't thought of turning the page, and now she seemed to be trying to stare right through it, as if enough staring would enable her to see what the man really looked like in the flesh.
"Mmm, I just can't control myself," she whispered.
Sliding up on the bed, Marie let her head and shoulders drop to the pillows clumped against the headboard. Then she shocked Kelly by pulling up the blouse, which was all she had on, exposing her long, slim legs and hairy pussy triangle.
Kelly's mouth opened wide in astonishment.
Before she could stop her little sister, Marie had splayed her milk-white legs wide apart and had slipped a finger into her wet, swollen pussy slit. Then she was finger fucking, moaning and humping her ass on the bed, staring at the centerfold as she fucked her fingers into the dripping mouth of her cunt slit.
"M-M-Marie!" Kelly stammered. "What in God's name do you think you're doing to yourself?"
"Jacking off," Marie said slowly. Harder and faster she fucked her finger into her gushing pussy, jacking off so wantonly that Kelly could see her pussy mouth sucking around the digit. "I'm so hot… unh… gotta beat…"
"Marie, stop that!" Kelly cried, raising her voice in spite of the fear that her parents would overhear. "You can't do that in my bedroom!"
But Marie ignored her big sister. Her face became dazed with lust as she whipped her fingers into her dripping, curly haired cunt, shuddering as she rolled her clit under her thumb.
Kelly didn't like the way she felt watching her sister. Her nipples were getting stiff, protruding through the sheer cotton nightie. Seconds later she felt a familiar wet heat invading her fleecy cunt.
"Marie, get out of my bedroom!"
"Noooo," Marie whimpered. She was rolling her head back and forth now, the center-fold momentarily forgotten as she lolled in the trance of feverish masturbation. "I want it, Marie. Unh! I want something to suck!"
Suddenly her little sister was all over her, moving with the quick ferocity of a sex-starved animal. Before Kelly could do anything to stop her, the horny brunette had pushed up her nightie, exposing her plump thighs and pussy triangle. Kelly gasped helplessly as she watched her horny sister bury her head between her legs.
"Marie! Oh my God, you stop that!"
"Wanna suck you!" Marie burbled. She pushed her hands under her sister's hips, clutching the firm, ball-bearing cheeks of her ass. Holding herself firm between her sister's legs, Marie rubbed her face all over Kelly's creaming cunt.
"Oh fuck, it smells so good, Kelly," she whimpered. "Let me suck it for you want your juice in my mouth! Let me suck your hot cunt."
"No!" Kelly was so shocked that she could only struggle fitfully to pull away. "Take your mouth off of my pussy! I mean it, noooo!"
"Mmmmm…"
Clawing her sister's ass cheeks, Marie thrust her tongue deep inside her big sister's fuck hole, pausing to curl it tantalizingly around Kelly's cunt. Abruptly a lewd shudder coursed through Kelly's body. She'd never had her pussy sucked before.
"Mmm, Kelly!" Marie giggled. "You really taste good!" Marie started to lap at Kelly's cunt slit like a horny dog, slurping noisily as she swiped her tongue quickly up and down.
"Unh, stop!" Kelly squealed, making a last effort to push her away. Then the pleasure of the pussy sucking started to get to her.
It felt much, much different than jacking off. Kelly whimpered, splaying her thighs wider apart, thrusting her plump cunt mound up to her sister's tongue. A befuddling fog seemed to wash over her mind. Dazedly she looked down at Marie's squirming black-haired head, unable to believe that her sister would want to taste her pussy juice.
"Mmmm," Marie whispered. "I think I'm gonna cum just from sucking you!"
Marie pulled her sister's ass cheeks apart and pressed them together again, making her pink virgin asshole pucker and throb. Her tongue rooted deep inside her sister's flowering pussy gash, drinking up the foaming fuck juices oozing from the depths of her cunt slit.
"Ungghhh!" Kelly's face contorted. She bucked as if she'd been shot when she felt Marie's tongue tease the underside of her cunt nubbin. "Oh… oh, Marie! I shouldn't let you do this to me! I'm losing control of myself!"
Marie giggled and rubbed her face all over Kelly's curly haired cunt mound, coating her cheeks with her sister's fuck juices. She was such a horny little slut, Kelly thought dazedly. But by now Kelly had realized how much she wanted Marie to do it, how badly she wanted to cum on Marie's mouth.
Marie pulled her hands from her sister's ass cheeks, letting the round little ass hump and dance off the mattress as Kelly's lust soared. Tenderly Marie slid her hands between Kelly's quivering thighs and peeled apart her pussy lips, opening up the glistening pinkness of her cunt gash, making her hard swollen cunt pop out of its fleshy hood.
"Unggh! No, don't touch me there!" Kelly gasped. "It's too sensitive."
Marie ignored her. Tenderly she pulled the folds of Kelly's cunt back all the way, exposing all of the protruding bud. Then she started to tongue it gently, quickly swiping her tongue up and down, directly on her clit.
"Aww awwwww Goddddd!" Kelly convulsively grabbed the back of her horny sister's head, digging her fingernails into her neck. The sensations pumping through her loins flow were the most intense she'd ever known. "Lick it!" she gasped, her voice rising. "Oooooh, fuck it! Lick my clit!"
Marie licked her sister's cunt wildly, never missing the tiny swollen bud with her tongue, licking as if she'd been sucking cunt all her life. Kelly felt her cunt popping out, getting harder, tingling and throbbing madly as fuck heat spread through, the inner depths of her cunt.
Wrapping her lips around the kernel-sized bud, Marie sucked her sister's clit hard. Then she suddenly fucked two fingers into her cunt hole, burying them to the knuckles in Kelly's throbbing, juicing pussy.
"Nunhhhh!" Kelly grimaced as she felt her pussy throb convulsively around the fingers, her ass burning as she started to cream. "Oh fuck, suck it, Marie! Harder, suck harder! Nnnnggggg fuck, fuck, I'm cuuummmiiinnnggg!"
Kelly's cunt spasmed, sucking uncontrollably around Marie's fingers. Sucking on her sister's aching cunt, Marie licked off her sister faster and harder, guiding her through the peak of her orgasm. Then she took her hand and mouth away from her gushing fuck hole and rested her cheek tenderly on Kelly's thigh.
"Satisfied?" she asked softly.
Kelly just rested there and panted. Her whole body was tingling, alive with a pleasure she'd never experienced before. Something in the back of her mind told her that she'd committed an act with her sister, an incestuous act that she'd never be able to atone for. But she didn't seem to care. It felt so good, she thought dizzily. No one had ever made her feel that way. It felt so fucking good.
"Now it's your turn to do me!" Marie cried. Rising from the bed, Marie hurriedly stripped off her blouse, leaving herself completely naked. Kelly's cheeks blushed with shame as she realized that looking at Marie was making her very horny. She had such a slim, lithe body, such firm, rounded tits and such stiff, purplish nipples. Her pussy creamed at the sight of Marie's small ass cheeks and cunt triangle.
"God, Kelly! Sometimes I wish I had really big tits like you!"
Falling back onto the bed, Marie hurriedly stripped off Kelly's nightie, leaving her naked too. Burying her head in Kelly's cleavage, Marie rolled her small hands over her sister's huge cherry-capped tits. Kelly found herself shuddering in spite of herself at her horny sister's touch, her tits swelling, the nipples crinkling stiff with passion.
Holding up one huge tit, Marie dropped her head and sucked the fat, crinkled nipple into her mouth. Furiously she sucked it, like a baby nursing for milk. Kelly squealed and twisted on the bed, rubbing her thighs together in a desperate effort to stop the wetness seething through her cunt.
"Now you're gonna suck me!" Acting as self-assured as any man, Marie grabbed her sister's ankles and pulled her down the bed. Then she straddled her face, planting her knees on the mattress to either side of her ears. "Suck it, Kelly! Suck it just like I sucked you! Suck off my fucking cunt!"
Kelly blushed at the sound of her sister's terse obscenities. Looking up, she found herself staring directly at the dark fur-fringed petals of Marie's cunt. The pink pussy gash was glistening with fuck oil, drooling from the depths of her cunt. Kelly could already smell Marie's pussy juices, and they were different from her own… thicker, more musky.
"Suck it, you bitch!" Marie cried. Grabbing Kelly's head, she dropped her ass and ground her mushy pussy onto her sister's mouth. "I'm so fucking hot! Suck the cream out of my cunt!"
Automatically Kelly slid her hands up Marie's sleek thighs, cupping the rounded cheeks of her tight ass. Kelly's mouth was covered by her sister's pussy, and she realized with some surprise how much the taste and feel of Marie's little cunt turned her on.
Kelly pushed out her tongue. Marie whined girlishly as it stabbed into her pouting pussy hole, probing the inner pinkness of her cunt tunnel. "Lick it!" Marie hissed. Reaching down, she spread her pussy lips, making her swollen clit pop out. "You know where, Kelly! Lick my cunt!"
Kelly twirled her tongue in and around her sister's throbbing fuck hole, making little smacking sounds as she lapped up the fragrant juices gushing out of Marie's cunt. Then she pressed her tongue on her cunt bud. Immediately Marie started humping, grasping and pulling Kelly's hair as she fucked her horny cunt all over her sister's face.
"Oh, fuck it, oooooh, fuck!" Marie bit her lip as she ground her cunt on Kelly's tongue, rocking her ass up and down. "Suck it," she hissed. "Put it in your mouth and fucking suck on it!"
Kelly rubbed her thighs together as she gave her sister head. By now her own pussy was so wet that she was afraid her fuck oil would foam out onto the mattress. Hornily she pulled apart Marie's ass cheeks, teasing her as her tongue danced across her arching cunt.
"Suck it, suck it for me!"
Kelly wrapped her lips around her little sister's clit. She sucked hard, pulling Marie's cunt out with her lips. At the same time, she pulled one hand from her bucking ass and slipped a finger deep inside her clinging cunt.
"Nnnnnggggg!" Marie humped harder, making her pussy muscles contract around the probing finger. "Oh, Kelly! I want you to jack off my asshole!"
"Wh-what!" Kelly was so astonished that she took her lips from her sister's throbbing clit.
"You heard me!" Hissing at her, Marie grabbed her hand and directed it between her ass cheeks. "My asshole gets horny too! Play with it! Jack it off!"
Kelly gasped, feeling her finger touching the small puckered ring. Never in her life had Kelly connected her asshole and sex, and the thought of fingering Marie's rubbery asshole would have disgusted her five minutes earlier.
But a strange, wanton heat had come over her, and she realized how utterly she'd succumbed to its spell. Returning her lips to Marie's swollen cunt. Kelly shamefully stabbed her finger into her small shit ring, burying it to the knuckle in the forbidden heat of her asshole.
Immediately Marie started humping her asshole onto her big sister's finger, simultaneously rocking her cunt mound onto her sister's mouth. "That's riiiiiight, that's so fucking goooood! Jack me off… unh, fuck… gonna cum!"
Kelly felt herself become increasingly aroused by the driven intensity of her sister's response. Almost violently, she slammed her finger into her sister's throbbing asshole, twisting it deep inside Marie's puckered shitter. At the same time, she sucked hard on Marie's clit, dancing her tongue repeatedly on the ultra-sensitive tip.
"Unngggghhhh!" Marie's face contorted. She started humping much harder, fucking her wet pussy all over Kelly's face. "Suck it suck it for me! Jack off my asshole! Unh! Fuck, Kelly! I'm making it now! My asshole's throbbing! Cuuummmiiinnnggg!"
Kelly felt her sister's whole body grow stiff, her thighs quivering as luscious heat mounted in her loins. Then her shit channel spasmed tightly around her fingers and the pouting lips of her pussy flooded her mouth with fuck juice.
Pussy juice bubbled out of her curly haired cunt slit, as heavy an explosion as a man's squirting cum. Kelly stopped sucking her sister's cunt and burrowed her tongue in Marie's pussy. Eagerly she licked out all the foaming cunt oil, pounding her finger into her burning ass guts.
"Unggghhh! Oh yes, lick me!" Marie kept humping and bucking. "Play with me! Ahhhh!"
Finally totally exhausted, the nymphomaniacal teenager rolled off of her sister's head and collapsed on her back on the bed. For a long time she just rested there, panting as she stared at the ceiling. Then she turned on her side and gave Kelly a long, tongue-sucking kiss.
"That was so fucking bitchin'," she whispered huskily. "You're a really good pussy sucker once you get started, Kelly! We'll do that lots more from now on!"
Kelly blushed even as her pussy thrilled to her sister's horny embrace. She felt horribly ashamed for giving in to the pleasures of the mutual sucking, and she resolved never to do it again. But at the same time she knew that Marie's tongue had awakened something inside her that could never be suppressed again.
