EVERYONE IN THIS STORY IS AT LEAST eighteen yr OLD OR OLDER.

Donnie Hamilton is the distinctive annoying teenaged little brother. There was just two twelvemonth difference of opinion in the ages of him and his big sister, Lucy. The immature way he acted, one would think there was much more of an age gap. She tolerated Donnie's juvenile behavior because she loved him. She learned to put up with his put-on because she understood Donnie was going through pubescence and was beginning to have an pursuit in lady friend. She also knew he was too young and inexperient to translate why he was attracted to the contrary sex. Every time she had her girl to their nursing home for a sleepover, he acted up.

Lucy is a beautiful young girl with prosperous hair, crystal blueness eyes, and luscious full lips. Donnie is the exact contrary of his sister. He is a improbable, gangly boy with freckles and large feet that made him uncoordinated and unsuited for sports or anything that required agility. Donnie had very few friends. Lucy, on the former manus, was one of the most pop miss in school. Lucy was a boy attractive feature, and boy would flow all over themselves to be near her. If she needed something, there was always a young man there to bring in it for her.

Lucy was captain of her cheerleader squad, president of her elderly class, and was elected homecoming poof two years in a row. Donnie was n't exactly ugly, but he seemed to repel most girls with his irregular conduct and unappealing appearances. He was a bit of a nerd who enjoyed science and computers.

Donnie had a chemical science set and often found chemical formula on the internet to use with experiments. One of his favourite was hydrogen sulfide ( rotten egg gas ) that he released one night when his baby had a slumber political party. Lucy 's bedroom smelled like farts the rest of the night, and the female child had to move their slumber party down to the den.

By the clip Donnie was 18 and a senior in mellow school, he was still a Virgo the Virgin and didn't have a girlfriend. He had started to discover breast but had only seen naked unity on the internet so far. The lone thing Donnie knew about sex, he had learned from porno sites. He still didn't know how to relate to the opposite sex successfully. He was somewhat like a ten-year-old boy who chased and pulled the hair of young woman he was attracted to on the vacation spot. He knew it was clip to get up and determine to act like a sexually experienced teenager.

Donnie was desperate to get a girlfriend and lose his virginity, so he checked his smut situation to see out what girls wanted in a fellow. He noticed that all the men on the porn sites had ten to twelve-inch pecker. Donnie measured his cock and found it was just a fraction under seven inches. He had to see a way to spring up a yearn rooster. He searched the net for a chemical chemical formula that promised a bigger, gruelling hammer and also claimed it would continue hard until a girlfriend was satisfied. It emphasized that staying hard was authoritative when it came to satisfying a woman.

Donnie got his chemistry set out and worked all afternoon, perfecting the implied knock-down anatomical change to his cock. After boiling off the liquidity, he ended up with four ounce of fine ovalbumin pulverisation. The internet directions guaranteed that one teaspoon of the gunpowder in a cup of liquid would pitch the pledged resultant. Donnie drank the intermixture and set about waiting for the chemical reaction to take place. By dinner time, nothing had changed. His cock was n't any longsighted, and he did n't feel any different.

After dinner, the family settled in the den to look on TV together. Donnie was fidgety and kept leaving the room every twenty to thirty minute of arc to check and see if there were any change to his peter. There was n't. He did appear to get an hard-on at the little stimulus, but that was fairly typical for a teenage boy with raging hormones. Around ten o'clock, the family retired to their chamber for the night. Donnie had a unsatisfied Night. He kept dreaming of bare girls parading before him. Every once in a while, his dream would let in his mother and baby among the naked girls.

Donnie came down for breakfast the next morning and took a footfall into the kitchen. His Mom was busy preparing breakfast as common, but something was different. Donnie shook his head and looked again. Why hadn't he noticed the flare of his Mom's coxa before ? She was wearing a dark-skinned knee-length skirt and a sheer Patrick White blouse that sort of hugged her shank. Her bum curved nicely under that skirt. The outline of her lacy white-hot bra was unmistakable under her sheer white shirt. Was that sexy ? For the low time in his liveliness, he thought it was. He could see the beau of the mighty English of her pinhead under her shirt, jiggling as she stirred the pancake mix with a boastfully spoon."sanctum cow, '' he thought to himself. He had never noticed before, but his Mom was hot. He got an erecting looking at his Mom. He had to sit down and enshroud it from her.

A bit later, Donnie's sister entered the kitchen and took her usual place across the table from him. Looking up from his breakfast, he stared at his big sister. How had he not noticed how pretty and delicate she was ? Soft amobarbital sodium eyes. A warm, engaging smile. His older babe looked different. Her bra shoulder strap are visible on her narrow down shoulders. And her knocker ? Oh, God, her boob are small and firm, just hanging out right there. How had he not noticed them before ? The accuracy is he'd never noticed Lucy like this before. Her trig petty hips. Her dainty nose. Her farseeing, slender neck. How had he never seen it before ? He tried to smile at her. His cock got uncomfortably heavily, and he attempted to acclimatise it covertly. His Mom gave him a quizzical expression. Donnie tried to enlist his big babe with small talking about the yearbook she was editing for her college but kept stumbling over his Word. He finally gave up and excused himself and left for school.

Donnie 's dick had n't made the change promised on the internet, so he studied the chemical chemical formula and decided that the dosage must depend on body exercising weight. Instead of one teaspoonful of the white powder, he put a tablespoonful in a cup of hot tea and pledge it with his dinner party. At about two o'clock in the morning time, Donnie woke up. It was still dark outside. He rolled over in his tangle of sheets and groaned. Something felt odd. Very odd. He tossed and turned, trying to get comfortable. Something was damage with his cock. Donnie rolled over, jumped out of bed, and pulled down his boxer shorts to study himself. His cock was hard, very hard. It was not any longer, but it was swollen fat and ached terribly. It was the worst case of dismal formal he had ever experienced. He urgently needed to cum. Donnie rushed to his bathroom, pushed his boxershorts down to his mortise joint, and began to masturbate aggressively. He tightened his hand around his concentrated cock and pounded away. simulacrum of his Mom and Sister surged into his head. He seized his cock and increased the rhythm. He was harder now than he had ever been in his life history. His cock was, indeed, a good deal to lay eyes on. The head was empurple and mushroom-shaped. The veins were sticking out and throbbing.

An 60 minutes later, Donnie still hadn't cum. Blood drained from his heading and filled his swollen turncock. He was becoming dizzy, and his arms felt like they were about to light off. He'd never experienced anything like it. He waddled over to the bathroom window with his boxershorts still around his ankle joint and pulled the window unresolved. The cold, crisp air cleared his head. Donnie kicked his boxers off and deposited them in the clothes hamper. Donnie shared a manual laborer n'Jill bathroom with his big sister, Lucy. He opened the doorway that connected the two bedrooms and made his way to his babe 's bed. Donnie sat on the boundary of his sister 's bed, crying because of his painfully hard, aching cock. He sobbed in bother as he shook her shoulder. She woke with a start and said, `` What is it, Donnie ? Why are you crying ? ``

"It's my cock,"he blubbered."It hurts so bad I can't stand it."

Lucy sat up in her bed and saw that Donnie was nude from the waistline down, and his cock was standing at attention. Lucy had never really given much consideration to her little brother's cock early than the few times she noticed his rousing creating a bulge in his pants.

"What the nether region do you desire me to do, Donnie ? I'm your SISTER ! I'm not supposed to see your…. your….. affair …. like that.

"Please help me, Lucy,"he pleaded,"I just need to cum."

"Well, go in the toilet and jack-off, or spank your monkey, or whatever the the pits guys do to make believe themselves cum,"Lucy bellowed.

'' I 've been beating off for over an minute and a half. I 've come close, but I have n't been capable to push myself over the border and cum, '' Donnie explained to his sis. `` I thought maybe if you did it, I would finally cum. ``

"Donnie ! I'm your SISTER ! I'm not supposed to touch my blood brother like that. It's not right. It's called incest."

"Please ! Please ! Please, Lucy ! I promise I will never ask you for another party favor as long as I live,"he begged."Just assist me cum this one time."

Lucy considered the torment on her little brother's expression. Her heart went out to him because she could see he was sincerely hurting. Lucy relented and asked her brother to lie on his rear. She then crawled between his stage. Lucy set back on her bounder and examined Donnie's cock for a import. She had seen a lot of cocks, but never a cock this tumid. Lucy dated a lot of guys in high school and college and had become very skilled at giving a handjob. It was n't one of her favorite thing, so she learned to get them off quickly.

Lucy wrapped her script around Donnie's prick and said,"You are going to owe me big prison term, Donnie."

Lucy placed both paw around her lilliputian pal's cock and felt the nervure and muscleman under his cutis. Donnie 's dick twitched and throbbed under his sister 's skilled touch. Lucy first used the 'twist and play'method acting, where she would slide both hands up and down his beam of light while twisting each hand in the antonym direction. Lucy would alternately glide the palm of her hand over the head of Donnie 's cock, every tertiary or fourth part head trip to the top of his ray of light, paying particular attention to his sensitive frenulum.

Both of those approaches usually got a guy off rather quickly. When neither worked on Donnie, she switched to what she referred to as the ‘ nuclear option .'An established technique that always resulted in an volatile orgasm. That technique consisted of gently massaging Donnie's balls with one hand while sliding her other hand up his pulsating cock to his mushroom as she again stimulated the frenulum. While continuing to make his quill in that mode, she tickled his egg with her fingertips. No one had ever lasted Thomas More than a few seconds under that method.

As chance would have it, aught happened. Lucy fell to her brother 's English, totally expel. Her coat of arms were aching, and her fingers were numb.

"Don't stop consonant,"Donnie shrieked,"I was almost there !"

"I'm sorry, Donnie. I've tried everything I know to do."

Donnie thought for a mo and then nervously proposed,"Well…not everything."

"What do you mean,"Lucy asked ?

Donnie hesitated a tenacious moment then gingerly said,"You haven't tried your mouth yet."

Lucy bolted upright piano in the bed and glared at her fiddling brother. Her face was red, and she could find the vehement heat rising from her shoulders and neck. Through clinch tooth, she growled, `` You are such a fucking pervert. I am your SISTER for God's sake ! Sisters don't give their brother blowjobs. No way am I going to let you stand by that monster in my mouth !"

Donnie thought for a minute and then said,"Can I bind it in your kitty-cat ?

"Absolutely not,"she growled !

Donnie started crying again and moaned,"It hurts so bad, Lucy. I can't stand it much longer. My balls have never felt so replete and hurt so badly. I know if I can vex it in something tender and wet, it will make me cum. ``

Lucy had always had a attender dapple in her heart when it came to her piffling brother. She could never sit by and let him goes through such suffering and pain without at least trying to relieve his pain sensation. Lucy leaned forward on her bridge player and knees, opening her mouth. In one relocation, she engulfed his thick cock to halfway. The heating plant that enveloped his groin was intoxicating. Donnie reached down and gripped the slope of her face. He watched in amazement as his sister gave him his low blowjob.

'' Mmmmmmmmm '' Lucy moaned as her backtalk glided up and down his shaft.

Donnie shuddered as Lucy swirled her knife around his sensitive tip. He thought his balls were slopped, but when her paw came up and cupped his full sack, Donnie thought he was going to drift properly there.

Lucy gave a mewling sound as Donnie began to make a motion his hips, slowly fucking his sister's mouth. He felt his engorged head bump the backbone of her throat but kept pumping. He'd been dreaming of this forever, and he would not be denied.

'' That 's it, Sis, suck your footling brother's cock. '' He groaned.

'' Yuullaakkkkk, '' Lucy tried to babble out as he shoved his stopcock down her throat.

Donnie felt his glob slap against Lucy's chin as he buried himself in her warm wet oral fissure, pushing until he felt his cock enter her throat. There was no doubtfulness of who was in charge now as seven column inch of his knockout cock stretched Lucy's throat with each thrust.

Donnie could hear Lucy taking breather through her nose, looking down he watched her spit dribble from the corner of her mouth and down her cute little Kuki. That sight alone was almost enough to take a shit him want to fellate his payload down her throat rightfulness then and there, but he didn't want to block off feeling the magnificent pleasure of his sister's mouth just yet.

Lucy's oculus fluttered exposed, and she stared up into his facial expression. She released her grip on Donnie 's shoulders and slid her hands down his back until she gripped a impertinence of his ass in each manus. She lifted his ass toward her font as she forced her mouth down onto his cock until it bumped the back of her throat.

Donnie could n't believe the slattern his sister had kept hidden inside. Every one of her deliberate campaign reeked of sex and lustfulness. When Lucy released Donnie's ass face from her clutches, he watched as Lucy's mouth sop up hard around his crown, and then slowly slid down until her nose was buried in his pubic hair. Donnie could finger his pecker enter his sister's pharynx again."Fuck, she had just deep throated him again,"he realized.

At the Lapp clock time, Lucy reached up and pulled her gown off, and he could only stare at her nude person body came into sentiment. There is null like having a naked and horny slut kneel between your legs with your pecker shoved down her pharynx, he thought.

Donnie could n't stand up it anymore. Reaching down, he intertwined his fingers into her blonde whisker, holding her head still he began to arch his rosehip. Donnie could find out her wet slurping as he began to have sex her hot mouth. He thought she might get mad, but instead, she only hummed her approving of him taking command. The vibration from her humming went straight to his boiling balls, sending his body into overburden and shutting his brain down at the same instant.

'' require it, Sis, suck my cock, '' he roared as his coming built. `` I think I am going to fucking cum, '' he told her !

Donnie arched his coxa up harder, driving deeper. He could hear Lucy start to gag on his distance, but she seemed to fee off his gesture. Donnie felt his balls slapping against his sister 's spit covered Chin. The visual modality of his cock buried down her throat was too much. He was on the wand of cumming.

Her mouth suddenly slipped off his pulsating cock, and she began to throb as her orgasm raced through her torso. Donnie felt the air pressure ease off his glands, making his balls start to settle back down. Lucy was still shaking and convulsing from her coming. Donnie clutched her to his pectus and pressed his lips to her parch brim. Their tongues found each former and danced.

Lucy disengaged from their osculation and said, `` Fuck me ... please ! '' She sounded like she was begging.

That was all Donnie needed ; he grasped his pulsing cock in one hand while he supported himself on the early. Aiming the engorged head to her swell labia, he lowered his pelvic girdle. Just as the tip of his cock touched her moistness, Donnie looked into her eyes. He could see the fire glowing in her eyes.

Donnie's rooster school principal parted Lucy's labia like wet petal as he slid the head inside, accompanied by a soft, moist sucking sound. He could feel her wet silky rampart gripping his shaft as he pushed deeper.

'' Oh, Saviour, '' Lucy groaned as she stared into his face. `` Slow Donnie, '' she gasped. `` I've never had anything this big in me. ``

Donnie's prick is the biggest cock she has ever had in her tight pussy, he realized. No wonder her wall felt like a velvet vise, she was as pixilated as a Virgin against his seven inch. With a grunt, he pushed down, down, down, sliding a couple more inches into her.

He watched as Lucy 's eyes fluttered again, her mouth opening in a unsounded"Oh"as her physical structure gave a small spasm under him. He could feel her nails dig lightly into his spinal column and then slowly eased up.

'' My God, '' Lucy breathed out a long sigh. `` I just came again, Donnie. screwing, that was good. '' A small smile crept over her face. `` Fuck your big Sister, good and hard slight Brother, '' she urged him.

With only half his cock inside her tight pussy, Donnie began to rock his hips, slowly sliding in and out of her now dripping slit. With each forward motion, he slipped more and more of his distance inside her.

'' Oh shit, '' Lucy groaned as his pelvic girdle came down on hers, his full seven inches now buried to the hilt inside her sop vagina. Lucy's traction tightened on her little buddy's articulatio coxae, holding him in place.

'' Do n't affect for a second, '' Lucy gasped."Let me do the workplace for a while."

He could feel her coxa grind in a irksome Mexican valium under him as her Venus mound pressed against his hip. There were rhythmic like waves pulsing along her blotto walls as his big sis skewered herself on his manhood.

'' Oh, fiddling brother, '' Lucy moaned `` I want ... I 'm going to ... I'm going to… '' Then Donnie watched as his babe's eyes slowly rolled back again.

'' Ooohhhhhhhh '' Lucy softly whimpered as her total body jerked under her footling brother. She stopped moving as a torrent of fluids gushed out to drench Donnie's cock and balls, and then slowly run down the cleft of Lucy's ass to souse the bed sheet under her.

'' Wow, '' Lucy whispered as her eye refocused on Donnie's nerve. `` Are you sure you were a Virgo, petty chum ? '' she asked.

'' I was until a moment ago, '' he smiled back. `` Why ? ``

'' Because you have already made me cum three times, '' she told him. `` Yet, you have n't even started to really bonk me. ``

Donnie pulled slowly back until just the head of his hammer rested inside her wet opening. Hovering over her, Donnie locked center with his Sister. Donnie gave a tacit thanks to time of day of watching porn that had prepared him to know what to do to delight his beautiful sister sexually.

'' Oh, so now you want me to get it on you,"he grunted ?"You mean like this ! ``

Donnie then rammed his cock down hard, slicing down through her velvet walls, driving deep, deep, mysterious. Lucy's legs shot out and then wrapped around her crony's waist as she scrapped her nails painfully down his back. He felt another blowup of warm up fluids wash his belly as her twenty-five percent orgasm ripped through her unprepared body.

'' Oh my, God ! YESSSS, '' Lucy screamed as she convulsed under him again.

Donnie's hips rose and fell as he pounded down into her with unrestraint. One advantage to her brother was an almost straight-out Energy Department provision supplemented by the chemical confection that kept his dick unusually surd. Wet slurping filled the room, as the aroma of their sex hung heavy in the air.

'' screwing me ... fuck me ... '' Lucy chanted as her little comrade, hammered into her. `` Own me, lilliputian brother, '' she said. `` I 'm yours for the taking. ``

Donnie knew he would n't last a great deal longer. It would be a welcome relief to his aching formal, but he did n't want the pleasure of his pecker sliding in and out of his babe to ever end. Donnie could hear his balls slapping his babe's cum soaked ass as he fucked into her with everything he had.

'' Oh, My fucking God, '' Lucy's eyes grew vast. `` Again ... oh fuck ... oh God ... '' Lucy gasped.

Donnie watched as Lucy devolved into a quivering mass under him. Her consistence was continuously jerking and spasming. Her bridge player slid up his back to the sides of his face.

'' My little comrade is making me cum so fucking hard, '' Lucy 's seriously lust-filled voice washed over Donnie's face.

Donnie felt Lucy's paries rippling along his irradiation, trying to milk the boiling cum from his balls. As he watched his big baby orgasm a fifth time, his body gave in to the wizard as his chunk started to reduce. Lucy gasped, her optic locking to his. Donnie tried to keep on looking into her eyes as his orgasm hit, honestly, but it was n't going to happen. Donnie's center rolled back in his headland as his released cum exploded from his balls and shot the length of his cock.

'' Oooohhh, '' Lucy gave a primal roar as the first blast jetted out to wash her spasming walls.

Donnie refocused on Lucy's face as Charles Herbert Best he could as his ass brass tightened, and a endorsement fit pumped out to flood her waiting pussy. He could see the flavour of wonder in her eyes.

'' Jesus, '' Lucy moaned. `` I can feel it, oh my God. '' She shuddered under him.

By the time the last muscle spasm of his cock hit, it had to be three or four hot rope he had let escaped inside her. Donnie rocked back on his blackguard between Lucy's lewdly circularise thigh, looking down between their joined bodies.

The erotic sight of his cock sliding from her tight snatch was exciting enough. Still, the additional image of Patrick White globs of cream that matted both their pubic hairs, as their mix in cream seeped from her sent a shiver down his spine.

'' I 'm no longer a virgin. '' Donnie crowed as he looked down at his beautiful sister.

'' No, you 're not '' Lucy reached up and ran her finger down his hairy chest. `` Now, my BIG fiddling brother is a man. '' She said.

As Donnie slid his cock free of Lucy's clutching pussy, he was thrilled to see it coated with their slick goo, and his balls no longer ached and throbbed. He was even more turn on to realize that after emptying his ballock, he was still tilt hard. He wanted more of his sister, and he intended to deliver her.

'' Am I your man ? '' Donnie asked as his sis stared riveted at his throbbing cock.

'' Forever petty brother, '' Lucy whispered back.

Donnie reached down and began to flap Lucy onto her breadbasket. Pulling up on her coxa, she rose to her mitt and knees on the bed. She looked over her shoulder joint at him as he positioned himself behind her. There was a fire in her eyes he had never seen before.

'' Are you going to bestride me ? '' Lucy growled. `` Are you going to Fuck your big sister like a bitch in heating plant ? ``

Donnie snarled with lustfulness as he dragged the self-conceited point of his dick along with his Sister 's cum soaked back talk. He never had in his life heard his babe public lecture like that ; it was as if she had become the slut he'd dreamed about.

'' I fucking sleep together this billet, '' Lucy moaned. `` It 's been too long since I was so slaked ; now fuck me like the woman of the street I am. Every hole I have belongs to you now, short brother. ``

Donnie slammed into her soaked kitty and asked,"Lucy, I know I promised you I would never ask for a favor like this again, but do you suppose you could format for me to fuck some of your sorority sisters the next time I get heavily like this ?"

"Donnie ! I'm your babe ! I get number one dibbed on your wonderful cock ! ”
