Title: Futa Sister Author: Forgottenidol girl/Futa size rough sisters pedo Summary: Emma thought she was alone in the house and would get some time to make herself feel good, but her sister Lizzy comes home from a bad day and finds her little sister in a perfect situation to help her relieve some stress Comments and feedback can be sent to novarask@protonmail.com Emma looked at herself in the mirror, breathing a little heavy. The ten year old was little for her age, easily the smallest girl in her class. Standing 4' 7, but barely 70 pounds. She was naked, looking over her narrow body with a critical eye. Her slight fingers ran over her tiny nipples which were stiff from the cool air in her room. She lamented how tiny they were. Other girls in her class were getting puffy nipples, or little breasts - it was hard not to notice. She sulked a bit, her hands moving up to her long brown pigtails that laid on her shoulders. She twirled them in her fingers. Playing with her hair always comforted her. Her eyes moved down her body. She was so slim, she could see the hint of each of her ribs, barely an once of fat on her. She didn't look unhealthy, just small. Her eyes continued down her belly, to the bare and bald little slit between her legs. Even it seemed tiny, barely noticeable if she squeezed her thighs together. She was the complete opposite of her older sister. Everyone knew Lizzy, she was a bit of an oddity growing up. Full figured by the age of twelve, outgoing, with a way of carrying herself that anyone knew she was in charge - Emma was a passive and uncertain as they came. By the time Lizzy graduated from high school, she was over six feet tall, curvy, muscular, with a chest it was hard to find bras far. It was so odd to think Emma was her sister. The little girl slid her hands to her butt, it was at least firm and bubbly, the only part of her with any real meat (though on anyone else it might look small.) She squeezed her cheeks a bit, sighed, grabbed her phone, and moved to her bed. Emma knew she was home alone and it would be some time before her sister was home from work. She lay on her bed and pulled her phone up, and bit her lip nervously. She made sure the volume was all the way down. No matter how alone she was, she always felt that someone could hear it. She pulled up one of her porn sites, seeing what was new. One caught her eye. It was called 'schoolgirl teen takes her teachers big cock.' She grinned and turned it on. The girl in it was dressed in a school uniform, kneeling in front of her teacher. Emma's hand slid down between her legs, her thin fingers rubbing the sensitive spot between her lips. She could already feel how warm she was. She watched as she rubbed herself. In the video, the girl was opening her teachers pants, reaching inside. Emma jump a little as she pulled the large thick cock out. Emma rubbed herself harder, her fingers feeling her wetness starting to flow. The girl rubbed and sucked her teacher's cock, the angry shaft looking angry with with veins as it got so big. Emma watched wide-eyed as she rubbed. Lizzy pulled up to the house, still angry about loosing her job. She cursed under her breath as she walked into the house. She went straight to her room, oblivious to everything around her. She tried to relax by getting on some comfortable clothes and washing up. She slipped into some sweat pants and a loose shirt after pulling her bra off. She headed out of her room and down the hall, and slipped into the bathroom. She felt so horny. She looked at herself. Even in her baggy sweat pants, the bulging outline of her most unique feature clearly stood out. She put her hand over the huge shaft, she felt it throbbing. Maybe she needed to call one of her fuck-buddies, she thought; work off a little aggression. She grinned at herself and washed up. Lizzy left the bathroom, and in the quiet of the house she could hear a faint huffing. She knew that sound. She moved quietly towards her sister's room, finding the door open a crack. She let out a little gasp when she saw her little sister on her bed, legs spread, watching her phone with her fingers going to town on what was the tiniest bald pussy she had ever seen. Before that moment, Lizzy never thought of her tiny little sister as anything sexual, but seeing her like that had her loins stirring. She watched her sister's slim fingers clumsily rubbing at herself. She watched, seeing just how far her sister was going. Emma had no idea she was being watched. Her fingers were wet from her pussy, little jolts shot through her when she rubbed her special little spot. On the video, the girl was bent over the teacher's desk, and he was behind her, his rock hard, large cock pounding into her stretched pussy. She pussy lips gripped it so tight, they slid out a little along his cock when he pulled back to slam into her again. In her young mind it was scary but exciting. She could not imagine her tiny pussy getting stretched like that, taking such a large thing as deep as the girl was. It made her so hot and dizzy. She was so lost that she didn't hear the door creek open, or the foot steps approaching, but she jumped when she felt hands grab her thin, spread thighs. Emma screamed loud, so startled by what was happening she flung her phone across the room. "L...L...Lizzy!..wha...what are...you..doing home?!" "Catching you apparently" Lizzy said as she pinned her little sister's spread legs down to the bed. She looked down between them. Even spread wide, the tiny pussy was barely opened, just a small hint of an opening that was red and shiny from the girl's attention. Lizzy grinned at Emma. "I know how to really make it feel good sis," she said and dropped her head to the ten year old's pussy. Emma was in shock, her brain struggling to process what was going on. Before she could make sense of it she felt a jolt of pleasure shoot up from her pussy unlike any thing she had felt with her own touch. Lizzy's mouth engulfed her pussy, Emma felt the thick wet tongue rolling against her overly petite pussy, pushing at it, grinding over her most sensitive spots. Emma couldn't help but to moan, her head falling back as she did. Emma had never felt so much pleasure, her hips bucked out of instinct, pushing her pussy against her sister's eager tongue. Lizzy sucked and moaned into her pussy. To Lizzy, it was the best pussy she had ever tasted, maybe because it was her little sister's. Lizzy rolled her tongue, feeling Emma buck wildly against it. The little girl was already so worked up that it didn't take long before she was crying out loud, her legs shaking. Her narrow hips lifted up from the bed. Emma was shaking, writhing under her sister's experienced efforts. She had never felt anything so intense and it just kept coming in wave after wave. She legs shook, toes curled and she bucked again and again until she felt weak. Still Lizzy sucked and ate at her delicate pussy. "Oh..L..Liiizzzyy...enough...sto..stop..please.." She begged, as she body shook and plopped back to the bed. Lizzy pulled her mouth away and licked her sister's juices from her lips. "Mmm..sis you taste great" she said. Emma looked up at her sister, panting and weak, body still trembling, legs spread wide. Lizzy just couldn't help herself, her fingers moved over Emma's tiny pussy, feeling it, teasing it. She pushed her fingertip against her micro-opening, feeling it struggle and resist. "Holy fuck sis, you have to have the tightest fucking pussy on earth..." Emma could just look up and moan, Lizzy's finger sending more little lightning strikes of pleasure through her. Lizzy could feel her monster throbbing in her pants. She moved up along her sisters slight little body, looking her over and smiling. "Mmm...but I think you owe me one, sis..I made you cum...so you can make me cum..." Lizzy pulled her shirt off, letting her huge firm tits plop out and hit her sister. She stood up and pulled Emma's firm little ass to the edge of the bed. Lizzy's hands ran over her slim body, so tiny against her own large frame. Lizzy bit her lip, she knew it was her sister but she was so horny. "I'm going to fuck the lights out of you, sis" Emma jumped feeling her sister pull her and control her in any way she wanted. Lizzy was absolutely huge compared to her, she was like a rag doll to her. Her mind was still spinning...how was Lizzy going to fuck her, she thought. The little girl didn't have to wait for an answer. Lizzy gripped the waist of her sweat pants and pulled them down, working them down her thighs and kicking them off her feet, freeing the monster that was hiding inside. With a thud, Lizzy gripped her beast and dropped it on the tiny girl's flat belly. Emma's eyes shot open, from feeling it and see it. Her mouth opened in a gasp and she felt her heart race. Her sister had a cock, but not just any cock. What was laying on her belly was the most immense cock she had ever seen. "Now you know why I was so popular," Lizzy chuckled and pressed her equally immense balls against her little sister's juvenile pussy. Emma felt it too, but her attention was glued to the giant shaft on her belly, running the length from her pussy, all the way along her belly, the head a few inched above her belly button. It wasn't just long, but so fat. It was bigger than any of the huge cocks she had seen in her videos - and it was still limp! She had no idea cock's like that existed. "Liz..Lizzy...N..no...way...I...I'm a virgin...sis" Emma stammered. "No shit Emma...but if I knew you were such a hot little slut I would have fucked you already...you are so hot all naked on your bed." Lizzy pushed down on her cock, grinding against Emma's smooth belly, humping against her a bit, feeling it throb and get harder. Emma started to struggle, seeing the cock thicken and the head sliding further up her body. She knew she couldn't fight off her sister. Her heart was racing, and she could barely breath. "Please...no...no sis...God it's so huge!" "MMmm..oh it's going to happen, sis...I'm going to take your cherry and ruin your pussy. I've never had such a young tight pussy, it's going to feel amazing..." Emma's eyes started watering and tears rolled down her cheeks. Lizzy's cock had grown so fast, the fat head was against Emma's chest and oozing, clear, hot precum. Staring down at it, Emma got dizzy again. The head staring at her face, yet her sister's huge ballsack still nestled firmly against her tender pussy. That cock would kill her she was certain. Emma cried harder. Lizzy was so turned on, she couldn't recall the last time her cock was so hard and swollen. She gripped it at the middle of the shaft, dragging down along her sister's slim, smooth body, leaving a trail of slick precum. She held her down, and pressed the massive swollen head of her cock against the smallest pussy she could have imagined. She pushed hard, feeling the tiny opening resist but slowly give in. It was so small. Lizzy grunted and thrust like a crazed animal while Emma wiggled her slim body in a vain attempt to get away. Slowly, painfully slowly, Emma's tiny young cunt was spreading wider, the massive fat head of LIzzy's rock hard cock was relentless, but barely half the tip in. "gahahh!" Emma gargled "Lizzy...it...it..hurts..please stop....plea..." Emma was cut off as Lizzy covered her mouth with her hand. "Shut up, sis...its not even in yet!" Lizzy growled again. Emma's eyes were wide in shock. Ripples of pain were shooting through her belly from her strained pussy. Lizzy thrust again and again, her big muscled flaring each time. Little Emma was at her mercy. "Fuck sis, you're so tiny and tight..." Lizzy was persistent, holding Emma down tightly as her massive member battered down through her resisting pussy, each hard thrust forcing the tiny hole to widen painfully. Emma moaned and screamed into Lizzy's hand. With another hard thrust, Lizzy felt the tiny pussy give, like a little pop the tight little lips snapped around her enormous head and squeezed her like nothing else. Emma wailed into Lizzy's hand, head shooting back as the intense pain of her virgin pussy getting split wide open radiated through her young body, making her tremble. She got dizzy and her vision faded. Lizzy felt her little sister go limp, but she could feel her heart racing through her stretched out pussy. She looked down at the lewd scene between her sisters slim lets. Her pussy wasn't noticeable anymore, just smooth, bare skin folding in against the massive cock. Lizzy pulled her hand from Emma's mouth, and gripped her slim hips, and slowly forced her swollen cock deeper. Lizzy groaned. It was tight, she felt Emma's flesh grating against her shaft as she drove in painfully slow. Each fraction of an inch causing a deep sigh from the tiny dazed girl. Lizzy grunted and groaned, precum oozing into the tight channel but barely helping her. Thrust after thrust, Emma's pussy was feeling better and better around her cock, as she brutally forced her little sister to take it. Fucking into her, Emma's limp legs bobbing beside her. Three then four inches. Emma's flat lower belly swelled out obscenely from the massive intruder. Lizzy watched, consumed by lust. Precum now sloshing around inside the tight channel, finally making it a bit easier to move. She pulled out just a fraction of and inch and slammed in again and again, a sloppy sound filling the room as the precum glistened against her cock. Each thrust forcing deeper into the helpless girl. Lizzy groaned. Emma's was the tightest pussy she had ever felt. Emma slowly came to, blurry eyes staring at the ceiling. She was numb at first, but slowly she became aware of a burning, jolting pain pulsing through her pussy and a hard cramping feeling in her belly. She rolled her head from side to side, slowly coming to and starting to whimper and cry. She felt her entire body being pushed and pulled on her bed, each push sending more pain up her belly. Tears ran from her eyes as she looked down. Her body trembled in shock, she saw her belly swelling up and down, her belly button swelling up and down in rhythm. Even lower she saw her sister's massive cock sliding a few inches in and out of her, her bare smooth skin being pulled out and pushed in by the force, become red and sore. "Ughhh...pl...please...sttt..tsttttop.." Emma's head rolled back again. "Welcome back, sis" Lizzy muttered through her groans as she kept steadily fucking in and out of her little sis. "No fucking way....you feel ssoooooo fucking good sis...fuck you are tight....I should have fucked you so long ago." Emma huffed and gasped at each hard thrust into her body. "I'mm...gonna...fuck...you...every...fucking....day....sis" Lizzy grunted between each thrust, working up a steady hard rhythm. Emma could only groan and whimper. Lizzy's cock felt like it was punching up into her stomach, lost in the pain and the stretched feeling when her belly would bulge out. She gasped as she felt Lizzy grab her legs and push them up, pinning them against her side and her feet hanging by her head. "Mmm..done with the warm up, Emma" Lizzy grunted and thrust hard, putting more of her weight into her thrusts. "Gahhh...AHhhh oooowoowwowo..." Emma screamed out, pressure building in her belly. She felt something pop inside her and her belly swell more. Lizzy's cock drove in deeper, filling her belly. "Ahh..yes...take my fucking cock, sis" Lizzy growled, slamming herself hard into Emma again and again. The bed creaking and Emma's slight body bouncing on her mattress. "My little sis, such a cock slut...so tight...my own little cocksleeve. Emma could just whimper and whine, her fists balled up into the sheets, holding on as Lizzy fucked her so hard and deep. Again and again, her head bouncing under the force. She was happy her body was going numb, but she still felt ever massive inch stretching and stuffing into her belly. Lizzy was relentless, for minutes just pounding and pounding. Emma thought her bed would break. With every passing minute Emma prayed that it would end. Until Lizzy finally pulled back, and her massive cock popped free with a loud, sloppy pop. Emma's legs dropped down, still spread wide. She gazed down, seeing her tiny pussy gaping, a huge red ring around her tender bald lips, swollen and raw from the brutal fucking. Emma panted, hoping it was over. Lizzy fell back, her massive cock popping up, coated with slick precum, even more oozing from the tip. She grinned down at her panting, dazed little sister, seeing her little pussy so red and raw. She rubs her cock. "Don't think for a second that I'm done..." Emma jerked when she heard that. Lizzy reached down and rolled her onto her belly. With a hard pop, Lizzy slapped Emma's ass hard, leaving a red mark. "Oww!" Emma cried. "Get on your fucking knees, slut..." Lizzy demanded, but Emma felt so weak. Lizzy gripped her hips and pulled her up, forcing Emma's knees under her and apart. "There you go sis.." Lizzy help her hips, and with a hard thrust, forced her massive cock back into her little sister. Emma cried again as she was suddenly filled and stretched again. Lizzy held onto her hip with one hand and gripped Emma's hair with the other. Emma cried out again as she felt her hair pulled. Her head and shoulders got yanked back as Lizzy thrust hard and deep into her pussy. Emma cried hard again, a fresh trail of tears running down her cheeks as she felt her belly swell again, feeling like her insides were mush. Lizzy fucked hard, every thrust yanking on Emma's hair, jerking her little body back. "Ohhh fuck...yes, Emma...my own personal fuck toy!" She groaned as she fucked her like a crazed animal. Emma was just lost, a whimpering, crying mess. Every thrust she was jerked back, and Lizzy's cock felt like it might burst from her belly. Her delicate fingers clawed at the sheets, pulling them up, bunching up beneath her as she failed to pull herself away from her sister. Lizzy growled, fucking her brutally. The room an orchestra of the slushy, wet slaps of the hard cock grinding away at Emma's once virgin pussy, and Emma's grunts and whimpers. Lizzy pushed harder against her, driving Emma forward into the headboard of her bed, her faced mashed against the wood. She gripped at it with her hands, holding on as she felt like Lizzy's cock was blending her insides into mush. The bed shook and creaked more, the back of the headboard slamming into the wall, denting it. Emma cried harder, her body contorted against the headboard with each brutal thrust. "Mmmm....fuck Emma...cry for me, you little slut...cry for your sister's cock" Lizzy grunted, "You're gonna make me cum so hard" Lizzy felt her cock burning and her balls tighten, her cock starting to swell even more. Emma felt it too. She felt her sore and bruised pussy getting pushed wider and she screamed out loud, crying and slapping her little hands against the headboard as Lizzy's cock somehow swelled thicker, the huge head flaring inside her. The cries were music to Lizzy at it drove her closer and closer to release. Emma nails scratched at the headboard, Lizzy jerked her back hard into each thrust, her head jerking back. Each thrust Emma felt her sister's cock nearly hitting the base of her ribs. "Uhhh...FUUUCKK Emmma!" Lizzy cried out, her cock flaring more as hot cum rushed up her long shaft, exploding a huge jet, flowing steady and forcefully for several seconds. Emma's little body shook as she felt the sudden surge of pressure in her belly, feeling it swell more and more as jet after jet of cum surged inside her, making her belly rounded. She felt she might burst, but Lizzy soon pulled back, her swollen cock popping free with another loud plop. Lizzy pushed her little sister down, quickly rolling her over on her back, seeing her belly swollen with cum. Lizzy gripped her cock as it still flared. Another shot of cum jetting out. Emma felt dizzy as she was suddenly jerked around. Her vision cleared just as she saw Lizzy's cock above her. Another shot of hot cum landed on her chest and belly, the next shot splattering in her face, forcing her to wince and gag a bit. She felt it oozing along her lips and down her chin. Then she felt another, a long string across her eyes up into her hair. Emma gasped, only to feel another shot of cum land in her mouth and tongue, making her gag more as she tried to spit it out. "oh Fuck no sis," Lizzy growled and gripped her head, pulling her parted lips to her cock, the head wedged firmly against it as another shot of cum filled her mouth. Emma gagged hard, feeling the sticky cum shoot right in her mouth, hitting her throat. She couldn't pull back, Lizzy held her firmly, her lips wedged on the tip of the massive cock as another shot of cum completely filled her mouth, her cheeks flaring out. "Ohhh I'm not done, you better swallow it sis" Lizzy groaned. Emma had no choice, she swallowed hard feeling her stomach turn as the thick cum ran down her throat. Her mouth cleared just as another large jet of cum splashed the back of her mouth. She closed her eyes and kept swallowing just to have her mouth filled again. Soon she felt like could not swallow any more. "Mmmm...good girl, swallow all your sister's cum" Lizzy grinned and finally let go of Emma's head, letting the girl fall back limply to the bed. The last few squirts of cum landing on Emma's body. Lizzy sat back, looking at the little girl panting and whimpering, cum running down her sides, running from her gaped and swollen pussy. Lizzy got up and stretched, her massive cock handing between her thighs. "I'll give you a break while I clean up....then we can have round two," Lizzy laughed as she walked from her sisters room, leaving the little girl as a sobbing, cum-covered mess....
