EVERYONE IN THIS STORY IS AT LEAST EIGHTEEN YEARS OLD OR OLDER.

Donnie Hamilton is the typical annoying teenaged little Brother. There was just two years conflict 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 person behavior because she loved him. She learned to put up with his pranks because she understood Donnie was going through pubescence and was beginning to have an pursuit in miss. She also knew he was too young and inexperienced to interpret why he was attracted to the opponent sex. Every time she had her girlfriends to their household for a sleepover, he acted up.

Lucy is a beautiful Danton True Young fille with golden pilus, watch crystal profane eyes, and delectable full moon sass. Donnie is the claim opposite of his sister. He is a tall, gangly boy with freckles and prominent foot that made him uncoordinated and unsuited for fun or anything that required nimbleness. Donnie had very few friends. Lucy, on the other hired hand, was one of the most popular daughter in school. Lucy was a boy magnet, and male child would shine all over themselves to be near her. If she needed something, there was always a young man there to fetch it for her.

Lucy was captain of her cheerleader team, president of her senior class, and was elected homecoming queen two year in a row. Donnie was n't exactly ugly, but he seemed to repulse most young woman with his irregular deportment and unappealing appearances. He was a bit of a nerd who enjoyed science and computers.

Donnie had a chemistry set and often found chemical formulas on the internet to use with experiments. One of his darling was hydrogen sulfide ( rotten egg gas ) that he released one night when his sister had a slumber party. Lucy 's bedchamber smelled like farts the sleep of the night, and the girls had to actuate their slumber party down to the den.

By the meter Donnie was eighteen and a senior in high school day, 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 I on the internet so far. The solitary matter Donnie knew about sex, he had learned from porn situation. 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's-breadth of daughter he was attracted to on the playground. He knew it was sentence to rise up and learn to act like a sexually experienced teenager.

Donnie was heroic to get a lady friend and suffer his virginity, so he checked his pornography sites to detect out what girl wanted in a beau. He noticed that all the men on the smut sites had ten to twelve-inch peter. Donnie measured his cock and found it was just a fraction under seven in. He had to chance a way to develop a long cock. He searched the internet for a chemical formula that promised a bigger, harder putz and also claimed it would detain hard until a girlfriend was satisfied. It emphasized that staying hard was important when it came to satisfying a fair sex.

Donnie got his chemical science set out and worked all afternoon, perfecting the involve powerful anatomical alteration to his dick. After boiling off the liquid, he ended up with four apothecaries' ounce of mulct egg white pulverisation. The net directions guaranteed that one teaspoonful of the pulverisation in a cup of liquid would deliver the pledged termination. Donnie drank the mixture and set about waiting for the reaction to occupy place. By dinner time, nothing had changed. His tool was n't any long, and he did n't feel any unlike.

After dinner party, the category settled in the den to see TV together. Donnie was fidgety and kept leaving the elbow room every twenty to thirty minutes to find out 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 hormones. Around ten o'clock, the kinsfolk retired to their bedrooms for the dark. Donnie had a restless dark. He kept dreaming of raw girls parading before him. Every once in a while, his dream would include his mother and sister among the naked girls.

Donnie came down for breakfast the next daybreak and took a step into the kitchen. His Mom was busy preparing breakfast as usual, but something was different. Donnie shook his head and looked again. Why hadn't he noticed the flare of his Mom's hip joint before ? She was wearing a dark knee-length skirt and a sheer white blouse that sort of hugged her shank. Her butt curved nicely under that skirt. The outline of her lacy white bra was unmistakable under her sheer white shirt. Was that sexy ? For the get-go time in his animation, he thought it was. He could see the fop of the right incline of her bosom under her shirt, jiggling as she stirred the pancake 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 cover it from her.

A moment later, Donnie's baby 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 ? diffused blue eyes. A warm up, engaging smiling. His sure-enough babe looked different. Her bra straps are seeable on her narrow shoulders. And her dumbbell ? Oh, God, her booby are minuscule 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 trim niggling hips. Her dainty nozzle. Her farseeing, lissome neck. How had he never seen it before ? He tried to smile at her. His stopcock got uncomfortably laborious, and he attempted to acclimate it covertly. His Mom gave him a questioning facial expression. Donnie tried to charter his big sister with small talk about the yearbook she was editing for her college but kept stumbling over his words. He finally gave up and excused himself and left for school.

Donnie 's tool had n't made the changes promised on the internet, so he studied the chemical formula and decided that the dosage must reckon on consistence weight. Instead of one teaspoonful of the white pulverization, he put a tablespoon in a cup of hot tea and drink it with his dinner party. At about two o'clock in the dawning, Donnie woke up. It was still disconsolate outside. He rolled over in his tangle of sheet 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 shortstop to examined 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 blue balls he had ever experienced. He urgently needed to cum. Donnie rushed to his bath, pushed his boxers down to his ankle joint, and began to fuck off aggressively. He tightened his hand around his hard stopcock and pounded away. Images of his Mom and baby surged into his school principal. He seized his cock and increased the rhythm. He was harder now than he had ever been in his life-time. His cock was, indeed, a sight to behold. The head was over-embellished and mushroom-shaped. The venous blood vessel were sticking out and throbbing.

An hour later, Donnie still hadn't cum. profligate drained from his head word and filled his conceited tool. He was becoming dizzy, and his arms felt like they were about to fall off. He'd never experienced anything like it. He waddled over to the can window with his boxershorts still around his mortise joint and pulled the window afford. The cold, crisp air cleared his oral sex. Donnie kicked his packer off and deposited them in the apparel hamper. Donnie shared a laborer n'Jill toilet with his big baby, Lucy. He opened the threshold that connected the two sleeping room and made his way to his sister 's bed. Donnie sat on the edge of his sis 's bed, crying because of his painfully punishing, aching cock. He sobbed in annoyance as he shook her berm. She woke with a start and said, `` What is it, Donnie ? Why are you crying ? ``

"It's my peter,"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 putz other than the few times she noticed his foreplay creating a gibbosity in his pant.

"What the Hell do you need me to do, Donnie ? I'm your baby ! I'm not supposed to see your…. your….. thing …. like that.

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

"fountainhead, go in the bathroom and jack-off, or larrup your monkey, or whatever the hell guys do to build themselves cum,"Lucy bellowed.

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

"Donnie ! I'm your baby ! I'm not supposed to meet 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 suffering on her picayune blood brother's aspect. Her heart went out to him because she could see he was sincerely hurting. Lucy relented and asked her brother to lie on his vertebral column. She then crawled between his pegleg. Lucy set back on her heels and examined Donnie's cock for a moment. She had seen a lot of cocks, but never a cock this turgid. Lucy dated a lot of guys in high-pitched shoal and college and had become very skilled at giving a handjob. It was n't one of her favourite things, so she learned to get them off quickly.

Lucy wrapped her handwriting around Donnie's stopcock and said,"You are going to owe me big time, Donnie."

Lucy placed both handwriting around her picayune brother's cock and felt the veins and muscle under his hide. Donnie 's stopcock twitched and throbbed under his sister 's skilled touch. Lucy first used the 'twist and number'method, where she would slide both manus up and down his prick while twisting each hand in the opposite focussing. Lucy would alternately glide the palm of her mitt over the head of Donnie 's turncock, every third or 4th trip to the top of his shaft, paying peculiar aid 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 pick .'An established technique that always resulted in an explosive coming. That technique consisted of gently massaging Donnie's orb with one hand while sliding her other bridge player up his pulsating cock to his mushroom as she again stimulated the frenulum. While continuing to act upon his cock in that manner, she tickled his bollock with her fingertips. No one had ever lasted more than a few seconds under that method.

As fate would have it, zip happened. Lucy fell to her pal 's slope, totally exhausted. Her arms were aching, and her fingerbreadth were numb.

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

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

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

"What do you have in mind,"Lucy asked ?

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

Lucy bolted upright piano in the bed and glared at her little chum. Her fount was red, and she could feel the fierce heat rising from her shoulders and cervix. Through clenched teeth, she growled, `` You are such a fuck pervert. I am your babe for God's sake ! babe don't give their brother cock sucking. No way am I going to let you deposit that fiend in my mouthpiece !"

Donnie thought for a minute of arc and then said,"Can I stick it in your kitty ?

"Absolutely not,"she growled !

Donnie started crying again and moaned,"It hurts so bad, Lucy. I can't place upright it much longer. My globe have never felt so full and hurt so badly. I know if I can puzzle it in something strong and wet, it will ready me cum. ``

Lucy had always had a tender spot in her heart when it came to her little brother. She could never sit by and let him goes through such torment and hurting without at to the lowest degree trying to alleviate his pain. Lucy leaned forward on her helping hand and stifle, opening her oral cavity. In one move, she engulfed his thick cock to halfway. The hotness that enveloped his bulwark was intoxicating. Donnie reached down and gripped the sides of her face. He watched in amazement as his sister gave him his starting time 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 balls were mingy, but when her hand came up and cupped his full firing, Donnie thought he was going to blow aright there.

Lucy gave a mewling sound as Donnie began to move his hips, slowly fucking his sister's mouth. He felt his gourmandize head bump the back 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 minuscule brother's pecker. '' He groaned.

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

Donnie felt his balls slap against Lucy's chin as he buried himself in her lovesome wet mouth, pushing until he felt his cock enter her throat. There was no enquiry of who was in tutelage now as seven inches of his strong 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 corner of her oral cavity and down her cunning little chin. That sight alone was almost decent to bring in him require to blow his load down her pharynx right then and there, but he didn't want to hold back feeling the glorious pleasure of his Sister's mouth just yet.

Lucy's centre fluttered open, and she stared up into his face. She released her hold on Donnie 's shoulders and slid her paw down his rachis until she gripped a cheek of his ass in each hand. She lifted his ass toward her grimace as she forced her mouth down onto his cock until it bumped the cover of her throat.

Donnie could n't consider the jade his sister had kept hidden inside. Every one of her look trend reeked of sex and lust. When Lucy released Donnie's ass cheeks from her grip, he watched as Lucy's mouth go down on toilsome around his cap, and then slowly skid down until her nose was buried in his pubic pilus. Donnie could feel his cock enter his babe's pharynx again."roll in the hay, she had just deep throated him again,"he realized.

At the same clip, Lucy reached up and pulled her nightie off, and he could only stare at her nude trunk came into view. There is nothing like having a au naturel and turned on strumpet kneel between your branch with your cock shoved down her throat, he thought.

Donnie could n't stand it anymore. Reaching down, he intertwined his fingers into her blond hair, holding her fountainhead still he began to arch his hips. Donnie could see her wet slurping as he began to fuck her hot backtalk. He thought she might get mad, but instead, she only hummed her approving of him taking command. The trembling from her humming went straight to his boiling orchis, sending his soundbox into overburden and shutting his brain down at the Sami instant.

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

Donnie arched his hips up harder, driving deeper. He could get a line Lucy bulge out to gag on his duration, but she seemed to eat off his motion. Donnie felt his balls slapping against his sister 's expectoration covered mentum. The sight of his cock buried down her throat was too very much. He was on the verge of cumming.

Her rima oris suddenly slipped off his pulsating cock, and she began to throb as her climax raced through her body. Donnie felt the pressure facilitate off his secretor, making his testicle start to finalize back down. Lucy was still shaking and convulsing from her sexual climax. Donnie clutched her to his chest and pressed his rim to her parched backtalk. Their tongues found each early and danced.

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

That was all Donnie needed ; he grasped his pulsing dick in one hand while he supported himself on the early. Aiming the engorged psyche to her swell up labia, he lowered his hips. Just as the tip of his turncock touched her dampness, Donnie looked into her middle. He could see the blast glowing in her eyes.

Donnie's pecker head parted Lucy's labia like wet petals as he slid the head inside, accompanied by a soft, moist sucking audio. He could feel her smashed silky walls gripping his cock as he pushed deeper.

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

Donnie's cock is the handsome cock she has ever had in her tight kitty-cat, he realized. No wonder her walls felt like a velvet vise, she was as tight as a virgin against his seven inch. With a oink, he pushed down, down, down, sliding a match more inch into her.

He watched as Lucy 's eyes fluttered again, her mouth opening in a dumb"Oh"as her body gave a diminished spasm under him. He could feel her nails dig lightly into his back and then slowly eased up.

'' My God, '' Lucy breathed out a long sigh. `` I just came again, Donnie. Fuck, that was salutary. '' A belittled smiling crept over her face. `` piece of ass your big sister, good and unvoiced little 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 kitty-cat. With each forward question, he slipped More and more of his length inside her.

'' Oh shit, '' Lucy groaned as his pelvis came down on hers, his full seven inches now buried to the hilt inside her sopping vagina. Lucy's adhesive friction tightened on her niggling Brother's hip, holding him in place.

'' Do n't incite for a second, '' Lucy gasped."Let me do the piece of work for a while."

He could feel her rose hip grind in a dim circle under him as her Urania hill pressed against his pelvis. There were rhythmic like waves pulsing along her tight walls as his big Sister skewered herself on his manhood.

'' Oh, little pal, '' 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 entire body jerked under her little brother. She stopped moving as a downpour of fluids gushed out to overcharge Donnie's cock and balls, and then slowly run down the crack of Lucy's ass to drench the sail under her.

'' Wow, '' Lucy whispered as her eyes refocused on Donnie's grimace. `` Are you sure you were a virgin, picayune brother ? '' she asked.

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

'' Because you have already made me cum three clock time, '' she told him. `` Yet, you have n't even started to really be intimate me. ``

Donnie pulled slowly back until just the fountainhead of his cock rested inside her wet opening. Hovering over her, Donnie locked eyes with his baby. Donnie gave a silent thanks to hours of watching porn that had prepared him to fuck what to do to delight his beautiful babe sexually.

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

Donnie then rammed his dick down hard, slicing down through her velvet walls, driving inscrutable, deep, rich. Lucy's legs shot out and then wrapped around her brother's shank as she scrapped her nails painfully down his back. He felt another gush of warm up fluids wash his belly as her quarter 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 vantage to her pal was an almost unlimited DOE supply supplemented by the chemical concoction that kept his dick unusually hard. Wet slurping filled the room, as the odor of their sex hung heavy in the air.

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

Donnie knew he would n't stopping point lots longer. It would be a welcome relief to his aching Lucille Ball, but he did n't require the pleasure of his cock sliding in and out of his sister to ever end. Donnie could hear his nut slapping his sister's cum soaked ass as he fucked into her with everything he had.

'' Oh, My Fucking God, '' Lucy's heart grew huge. `` Again ... oh fuck ... oh God ... '' Lucy gasped.

Donnie watched as Lucy devolved into a quivering mass under him. Her organic structure was continuously jerking and spasming. Her script slid up his spine to the sides of his face.

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

Donnie felt Lucy's walls rippling along his shaft, trying to milk the boiling cum from his balls. As he watched his big sister orgasm a twenty percent clip, his organic structure gave in to the genius as his musket ball started to tighten. Lucy gasped, her eyes locking to his. Donnie tried to keep looking into her eyes as his orgasm hit, honestly, but it was n't going to happen. Donnie's heart rolled back in his head as his released cum exploded from his glob and shot the length of his cock.

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

Donnie refocused on Lucy's facial expression as best he could as his ass cheeks tightened, and a moment burst pumped out to swamp her waiting snatch. He could see the feeling 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 rophy he had let loose inside her. Donnie rocked back on his heels between Lucy's lewdly banquet thighs, looking down between their joined bodies.

The erotic sight of his cock sliding from her squiffy pussy was exciting enough. Still, the extra image of Theodore Harold White clump of cream that matted both their pubic hairs, as their mixed ointment seeped from her sent a tingle 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 thorax. `` Now, my BIG little brother is a man. '' She said.

As Donnie slid his cock free of Lucy's clutching snatch, he was thrilled to see it coated with their slip goo, and his balls no longer ached and throbbed. He was even more charge up to realize that after emptying his balls, he was still rock hard. He wanted more of his baby, and he intended to have got her.

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

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

Donnie reached down and began to wheel Lucy onto her stomach. Pulling up on her pelvic girdle, she rose to her helping hand and knees on the bed. She looked over her shoulder at him as he positioned himself behind her. There was a firing in her eyes he had never seen before.

'' Are you going to mount me ? '' Lucy growled. `` Are you going to Fuck your big sis like a bitch in passion ? ``

Donnie snarled with lust as he dragged the egotistical head of his rooster along with his sister 's cum soaked lip. He never had in his life heard his sister talk like that ; it was as if she had become the slut he'd dreamed about.

'' I fucking love this stead, '' Lucy moaned. `` It 's been too long since I was so satisfy ; now fuck me like the working girl I am. Every hole I have belongs to you now, little crony. ``

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

"Donnie ! I'm your sister ! I get commencement dibbed on your wonderful cock ! ”
