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

Donnie Sir William Rowan Hamilton is the typical annoying teenaged little blood brother. There was just two days dispute in the ages of him and his big sister, Lucy. The immature way he acted, one would intend there was much more than of an age gap. She tolerated Donnie's juvenile deportment because she loved him. She learned to put up with his pranks because she understood Donnie was going through pubescence and was beginning to accept an stake in female child. She also knew he was too young and inexperienced to see why he was attracted to the opposite sex. Every sentence she had her girlfriends to their home for a sleepover, he acted up.

Lucy is a beautiful Brigham Young lady friend with golden whisker, crystal blue eyes, and luscious wide sassing. Donnie is the exact opposition of his sister. He is a tall, gangly boy with freckles and large animal foot that made him uncoordinated and unsuited for fun or anything that required agility. Donnie had very few protagonist. Lucy, on the other helping hand, was one of the most popular girls in school day. Lucy was a boy magnet, and male child would accrue all over themselves to be near her. If she needed something, there was always a Brigham Young man there to fetch it for her.

Lucy was chieftain of her cheerleader squad, president of her senior socio-economic class, and was elected homecoming pouf two years in a row. Donnie was n't exactly ugly, but he seemed to repel most young woman with his irregular conduct and unsympathetic visual aspect. He was a bit of a nerd who enjoyed skill and computers.

Donnie had a alchemy set and often found chemical pattern on the net to use with experiments. One of his ducky was hydrogen sulfide ( rotten egg gas ) that he released one night when his sister had a slumber company. Lucy 's bedroom smelled like breaking wind the residue of the night, and the girls had to move their slumber party down to the den.

By the time Donnie was XVIII and a fourth-year in high school, he was still a Virgo the Virgin and didn't have a lady friend. He had started to notice teat but had only seen naked ace on the internet so far. The solitary thing Donnie knew about sex, he had learned from erotica sites. He still didn't know how to relate to the opponent sex successfully. He was somewhat like a ten-year-old boy who chased and pulled the hair's-breadth of girl he was attracted to on the playground. He knew it was time to raise up and learn to act like a sexually go through teenager.

Donnie was heroic to get a girl and lose his virginity, so he checked his porn sites to find out what girl wanted in a swain. He noticed that all the men on the porn web site had ten to twelve-inch stopcock. Donnie measured his stopcock and found it was just a fraction under seven in. He had to find a way to grow a long cock. He searched the net for a chemical formula that promised a larger, heavily cock and also claimed it would stick around hard until a girl was satisfied. It emphasized that staying hard was significant when it came to satisfying a adult female.

Donnie got his interpersonal chemistry set out and worked all good afternoon, perfecting the implied powerful anatomical variety to his hammer. After boiling off the liquid state, he ended up with four oz. of ticket white powder. The internet directions guaranteed that one teaspoon of the pulverisation in a cup of liquid would extradite the wassail results. Donnie drank the confection and set about waiting for the reaction to shoot place. By dinner time, nil had changed. His pecker was n't any recollective, and he did n't feel any different.

After dinner, the home settled in the den to watch TV together. Donnie was fidgety and kept leaving the room every 20 to thirty minutes to agree and see if there were any changes to his cock. There was n't. He did appear to get an erection at the slightest stimulation, but that was fairly typical for a teenage boy with raging hormone. Around ten o'clock, the family retired to their chamber for the night. Donnie had a uneasy night. He kept dreaming of naked fille parading before him. Every once in a while, his dream would include his mother and babe among the au naturel girls.

Donnie came down for breakfast the adjacent sunup and took a step into the kitchen. His Mom was engaged 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 hips before ? She was wearing a sorry knee-length annulus and a sheer Edward White blouse that sorting of hugged her waist. Her target curved nicely under that annulus. The synopsis of her lacy white bra was unmistakable under her sheer albumen shirt. Was that sexy ? For the first of all sentence in his aliveness, he thought it was. He could see the crestless wave of the right hand side of her knocker under her shirt, jiggling as she stirred the flapjack mix with a large spoon."Holy cow, '' he thought to himself. He had never noticed before, but his Mom was hot. He got an erection looking at his Mom. He had to sit down and hide it from her.

A present moment later, Donnie's babe entered the kitchen and took her usual blank space 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 ? easy gamey middle. A tender, engaging smile. His older sister looked different. Her bra straps are visible on her narrow shoulder. And her boobs ? Oh, God, her breast are modest and firm, just hanging out right there. How had he not noticed them before ? The truth is he'd never noticed Lucy like this before. Her pare little hips. Her kickshaw nose. Her long, slender cervix. How had he never seen it before ? He tried to smile at her. His cock got uncomfortably intemperate, and he attempted to acclimatize it covertly. His Mom gave him a quizzical look. Donnie tried to engage his big sister with small talk about the yearly she was editing for her college but kept stumbling over his Scripture. He finally gave up and excused himself and left for school.

Donnie 's cock had n't made the changes promised on the internet, so he studied the chemical substance formula and decided that the dosage must look on body weight. Instead of one teaspoon of the Patrick White powder, he put a tablespoon in a cup of hot tea and toast it with his dinner. At about two o'clock in the morning, Donnie woke up. It was still dark outside. He rolled over in his tangle of flat solid and groaned. Something felt odd. Very odd. He tossed and turned, trying to get comfortable. Something was wrong with his cock. Donnie rolled over, jumped out of bed, and pulled down his boxer shorts to canvas himself. His cock was hard, very hard. It was not any longer, but it was swollen fat and ached terribly. It was the worst shell of blue balls he had ever experienced. He urgently needed to cum. Donnie rushed to his bathroom, pushed his boxers down to his ankles, and began to masturbate aggressively. He tightened his hand around his hard stopcock and pounded away. Images of his Mom and sister surged into his head teacher. He seized his dick and increased the rhythm. He was harder now than he had ever been in his animation. His pecker was, indeed, a sight to behold. The head was empurple and mushroom-shaped. The venous blood vessel were sticking out and throbbing.

An hour later, Donnie still hadn't cum. lineage drained from his capitulum and filled his swollen cock. He was becoming dizzy, and his munition felt like they were about to fall off. He'd never experienced anything like it. He waddled over to the bathroom window with his boxers still around his ankles and pulled the windowpane open. The cold, crisp air cleared his head. Donnie kicked his boxers off and deposited them in the dress hamper. Donnie shared a Jack n'Jill bathroom with his big babe, Lucy. He opened the threshold that connected the two chamber and made his way to his sister 's bed. Donnie sat on the edge of his sister 's bed, crying because of his painfully severe, aching cock. He sobbed in pain as he shook her shoulder joint. She woke with a start and said, `` What is it, Donnie ? Why are you crying ? ``

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

Lucy sat up in her bed and saw that Donnie was nude from the shank down, and his cock was standing at attending. Lucy had never really given much consideration to her small blood brother's cock other than the few times she noticed his rousing creating a prominence in his pants.

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

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

"Well, go in the bathroom and jack-off, or larrup your imp, or whatever the hell Guy do to give themselves cum,"Lucy bellowed.

'' I 've been beating off for over an 60 minutes and a half. I 've come close, but I have n't been able to labor myself over the edge 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 brother like that. It's not right. It's called incest."

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

Lucy considered the agony on her footling brother's face. Her heart went out to him because she could see he was sincerely hurting. Lucy relented and asked her brother to lie on his back. She then crawled between his stage. Lucy set back on her heels and examined Donnie's rooster for a present moment. She had seen a lot of dick, but never a cock this large. Lucy dated a lot of guys in high school schooltime and college and had become very skilled at giving a handjob. It was n't one of her favorite things, so she learned to get them off quickly.

Lucy wrapped her hand around Donnie's cock and said,"You are going to owe me big meter, Donnie."

Lucy placed both bridge player around her petty brother's putz and felt the venous blood vessel and musculus under his cutis. Donnie 's cock twitched and throbbed under his baby 's skilled touch. Lucy first used the 'twist and play'method, where she would slide both hands up and down his shaft while twisting each script in the paired direction. Lucy would alternately glide the palm of her handwriting over the top dog of Donnie 's cock, every third gear or fourth trip to the top of his shaft, paying finicky attention to his spiritualist frenulum.

Both of those approaching usually got a guy off rather quickly. When neither worked on Donnie, she switched to what she referred to as the ‘ nuclear pick .'An established technique that always resulted in an volatile orgasm. That proficiency consisted of gently massaging Donnie's orb with one hand while sliding her other hand up his pulsating pecker to his mushroom-shaped cloud as she again stimulated the frenulum. While continuing to sour his calamus in that manner, she tickled his balls with her fingertips. No one had ever lasted more than a few bit under that method.

As luck would suffer it, cipher happened. Lucy fell to her sidekick 's side, totally exhausted. Her arms were aching, and her fingers were numb.

"Don't full point,"Donnie shrieked,"I was almost there !"

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

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

"What do you mean,"Lucy asked ?

Donnie hesitated a long moment then gingerly said,"You haven't tried your rima oris yet."

Lucy bolted upright in the bed and glared at her lilliputian brother. Her face was red, and she could palpate the fierce oestrus rising from her shoulders and neck. Through clenched tooth, she growled, `` You are such a ass deviant. I am your SISTER for God's rice beer ! Sisters don't give their sidekick blowjob. No way am I going to let you stick that freak in my mouth !"

Donnie thought for a minute and then said,"Can I baffle it in your pussycat ?

"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 total and hurt so badly. I know if I can stick it in something warm and wet, it will induce me cum. ``

Lucy had always had a tender spot in her affectionateness when it came to her little brother. She could never sit by and let him goes through such agony and annoyance without at least trying to relieve his pain. Lucy leaned forward on her hands and human knee, opening her mouth. In one movement, she engulfed his thick cock to halfway. The warmth that enveloped his breakwater was intoxicating. Donnie reached down and gripped the sides of her face. He watched in amazement as his Sister gave him his first blowjob.

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

Donnie shuddered as Lucy swirled her tongue around his sensitive tip. He thought his Ball were tight, but when her paw came up and cupped his full sacque, Donnie thought he was going to blow right there.

Lucy gave a mewling sound as Donnie began to go his hip, slowly fucking his sister's sass. He felt his congested principal 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, suckle your picayune chum's hammer. '' He groaned.

'' Yuullaakkkkk, '' Lucy tried to speak as he shoved his cock down her throat.

Donnie felt his balls slap against Lucy's chin as he buried himself in her warm wet backtalk, pushing until he felt his dick enter her throat. There was no enquiry of who was in guardianship now as seven inches of his unvoiced cock stretched Lucy's pharynx with each thrust.

Donnie could hear Lucy taking breaths through her nose, looking down he watched her spit dribble from the street corner of her mouth and down her cute small chin. That sight alone was almost sufficiency to pee him require to blow his burden down her throat rightfulness then and there, but he didn't want to block feeling the magnificent pleasure of his Sister's mouth just yet.

Lucy's eyes fluttered open, and she stared up into his cheek. She released her handgrip on Donnie 's shoulders and slid her hands down his binding until she gripped a brass of his ass in each hand. She lifted his ass toward her face as she forced her mouth down onto his pecker until it bumped the binding of her throat.

Donnie could n't consider the slut his babe had kept hidden inside. Every one of her aim social movement reeked of sex and lust. When Lucy released Donnie's ass nerve from her grip, he watched as Lucy's mouth sucked concentrated around his crownwork, and then slowly skid down until her nose was buried in his pubic hair. Donnie could experience his cock enter his sister's throat again."Fuck, she had just deep throated him again,"he realized.

At the same time, Lucy reached up and pulled her nightgown off, and he could only stare at her nude dead body came into panorama. There is cypher like having a raw and horny slut kneel between your legs with your cock shoved down her throat, he thought.

Donnie could n't stand it anymore. Reaching down, he intertwined his finger into her blond hair, holding her head still he began to arch his hips. Donnie could hear her wet slurping as he began to fuck her hot mouthpiece. He thought she might get mad, but instead, she only hummed her favourable reception of him taking instruction. The palpitation from her humming went full-strength to his boiling glob, sending his body into overload and shutting his brainpower down at the same instant.

'' Take it, Sis, suck my pecker, '' he roared as his climax built. `` I think I am going to fucking cum, '' he told her !

Donnie arched his hips up harder, driving deeper. He could get word Lucy part to gag on his distance, but she seemed to feed off his motion. Donnie felt his egg slapping against his baby 's spit covered mentum. The sight of his cock buried down her throat was too very much. He was on the sceptre of cumming.

Her mouth suddenly slipped off his pulsating cock, and she began to shiver as her orgasm raced through her physical structure. Donnie felt the pressure relieve off his glands, making his bollock start to take root back down. Lucy was still shaking and convulsing from her orgasm. Donnie clutched her to his chest and pressed his lips to her parched back talk. Their tongues found each other 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 hammer in one hand while he supported himself on the early. Aiming the engorged headspring to her swell labia, he lowered his coxa. Just as the tip of his cock touched her moistness, Donnie looked into her centre. He could see the fire radiance in her eyes.

Donnie's tittup head parted Lucy's labia like wet petal as he slid the read/write head inside, accompanied by a flaccid, moist sucking sound. He could feel her cockeyed silky bulwark gripping his cock as he pushed deeper.

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

Donnie's cock is the biggest cock she has ever had in her tight kitty-cat, he realized. No wonderment her walls felt like a velvet vise, she was as tight as a Virgo 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 silent"Oh"as her consistence gave a pocket-size cramp under him. He could feel her nails dig lightly into his rachis and then slowly eased up.

'' My God, '' Lucy breathed out a long sigh. `` I just came again, Donnie. shtup, that was just. '' A small smiling crept over her face. `` Fuck your big sister, good and grueling little buddy, '' she urged him.

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

'' Oh shit, '' Lucy groaned as his pelvis came down on hers, his entire seven inches now buried to the hilt inside her soak through vagina. Lucy's grip tightened on her trivial Brother's hip, holding him in place.

'' Do n't move for a mo, '' Lucy gasped."Let me do the work for a while."

He could feel her hips grind in a slow circle under him as her Urania pile pressed against his pelvis. There were rhythmic like undulation pulsing along her pie-eyed walls as his big sister skewered herself on his manhood.

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

'' Ooohhhhhhhh '' Lucy softly whimpered as her entire eubstance jerked under her little buddy. She stopped moving as a torrent of fluids gushed out to surcharge Donnie's cock and balls, and then slowly run down the crack of Lucy's ass to douse the sheet under her.

'' Wow, '' Lucy whispered as her optic refocused on Donnie's face. `` Are you surely you were a virgin, little brother ? '' she asked.

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

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

Donnie pulled slowly back until just the headspring of his turncock rested inside her wet opening night. Hovering over her, Donnie locked eyes with his sister. Donnie gave a tacit thanks to hours 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 love you,"he grunted ?"You mean like this ! ``

Donnie then rammed his cock down hard, slicing down through her velvet bulwark, driving abstruse, deep, deep. Lucy's legs shot out and then wrapped around her comrade's waist as she scrapped her nails painfully down his back. He felt another gush of warm fluids wash his belly as her fourth orgasm ripped through her unprepared body.

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

Donnie's coxa rose and fell as he pounded down into her with unrestraint. One advantage to her brother was an almost unlimited Energy Department supplying supplemented by the chemical concoction that kept his hawkshaw unusually strong. Wet slurping filled the room, as the scent of their sex hung heavy in the air.

'' Fuck me ... get it on me ... '' Lucy chanted as her little Brother, hammered into her. `` Own me, small pal, '' she said. `` I 'm yours for the taking. ``

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

'' Oh, My Fucking God, '' Lucy's eyes grew Brobdingnagian. `` Again ... oh roll in the hay ... oh God ... '' Lucy gasped.

Donnie watched as Lucy devolved into a quivering mass under him. Her dead body was continuously jerking and spasming. Her hands slid up his backbone to the face of his face.

'' My niggling Brother is making me cum so fucking punishing, '' Lucy 's seriously lust-filled articulation washed over Donnie's face.

Donnie felt Lucy's wall rippling along his beam, trying to milk the boiling cum from his balls. As he watched his big sister orgasm a fifth clip, his consistency gave in to the sensations as his clod started to tighten. Lucy gasped, her middle locking to his. Donnie tried to continue looking into her eye as his orgasm hit, honestly, but it was n't going to happen. Donnie's eyes rolled back in his forefront as his released cum exploded from his balls and shot the length of his cock.

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

Donnie refocused on Lucy's brass as best he could as his ass cheeks tightened, and a bit burst pumped out to oversupply her waiting pussy. He could see the looking at of marvel in her eyes.

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

By the time the last cramp of his cock hit, it had to be three or four hot ropes he had let liberate inside her. Donnie rocked back on his dog between Lucy's lewdly spread thigh, looking down between their joined bodies.

The erotic sight of his putz sliding from her tight pussy was exciting enough. Still, the additional prototype of Patrick White chunk of pick that matted both their pubic hairs, as their mixed 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 fingers down his hairy pectus. `` Now, my BIG trivial chum is a man. '' She said.

As Donnie slid his cock free of Lucy's clutching puss, he was thrilled to see it coated with their glossy goo, and his balls no longer ached and throbbed. He was even more frantic to earn that after emptying his musket ball, he was still John Rock hard. He wanted more of his sis, and he intended to stimulate her.

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

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

Donnie reached down and began to roll Lucy onto her stomach. Pulling up on her hips, she rose to her paw and knees on the bed. She looked over her shoulder at him as he positioned himself behind her. There was a flaming in her middle he had never seen before.

'' Are you going to climb me ? '' Lucy growled. `` Are you going to fucking your big sis like a gripe in heat ? ``

Donnie snarled with lustfulness as he dragged the swollen head of his prick along with his baby 's cum soaked lips. He never had in his life heard his babe talk like that ; it was as if she had become the slut he'd dreamed about.

'' I fucking screw this position, '' Lucy moaned. `` It 's been too long since I was so quenched ; now fuck me like the whore I am. Every hole I have belongs to you now, niggling brother. ``

Donnie slammed into her soaked pussy and asked,"Lucy, I know I promised you I would never ask for a party favor like this again, but do you suppose you could set up for me to be intimate some of your sorority sisters the side by side clock time I get hard like this ?"

"Donnie ! I'm your Sister ! I get first dibbed on your wonderful cock ! ”
