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

Donnie Amy Lyon is the distinctive annoying teenaged piffling comrade. There was just two yr dispute in the age 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 buffoonery because she understood Donnie was going through pubescence and was beginning to have an interest in girls. She also knew he was too new and inexperienced to interpret why he was attracted to the opposite word sex. Every meter she had her girlfriends to their home for a sleepover, he acted up.

Lucy is a beautiful Loretta Young girl with gold pilus, vitreous silica blue eyes, and luscious full lips. Donnie is the accurate antonym of his sister. He is a tall, gangly boy with freckles and heavy infantry that made him uncoordinated and ill-sorted for fun or anything that required legerity. Donnie had very few acquaintance. Lucy, on the other hired hand, was one of the most popular girls in school day. Lucy was a boy magnet, and boys would strike all over themselves to be near her. If she needed something, there was always a offspring man there to fetch it for her.

Lucy was captain of her cheerleader team, president of her elder social class, and was elected homecoming queen mole rat two years in a row. Donnie was n't exactly ugly, but he seemed to gross out most girls with his irregular conduct and unappealing appearing. He was a bit of a nerd who enjoyed science and computers.

Donnie had a chemistry set and often found chemical convention on the cyberspace 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 political party. Lucy 's bedroom smelled like farts the residuum of the Nox, and the young lady had to move their slumber party down to the den.

By the time Donnie was XVIII and a senior in high school, he was still a virgin and didn't have a girl. He had started to notice tits but had only seen naked single on the internet so far. The lone affair Donnie knew about sex, he had learned from erotica web site. 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 girls he was attracted to on the playground. He knew it was metre to grow up and see to act like a sexually experienced teenager.

Donnie was desperate to get a girlfriend and lose his virginity, so he checked his porn sites to find out what young lady wanted in a young man. He noticed that all the men on the erotica sites had ten to twelve-inch pecker. Donnie measured his cock and found it was just a fraction under seven inch. He had to find a way to spring up a recollective turncock. He searched the internet for a chemical formula that promised a bigger, harder cock and also claimed it would stay hard until a girlfriend was satisfied. It emphasized that staying hard was important when it came to satisfying a woman.

Donnie got his alchemy set out and worked all afternoon, perfecting the implied knock-down anatomical reference changes to his cock. After boiling off the liquid, he ended up with four ounces of fine white powder. The internet directions guaranteed that one teaspoon of the powder in a cup of liquid would surrender the pledged results. Donnie drank the concoction and set about waiting for the reaction to make property. By dinner sentence, nothing had changed. His peter was n't any longer, and he did n't feel any different.

After dinner, the mob settled in the den to watch TV together. Donnie was fidgety and kept leaving the elbow room every twenty to thirty minutes to check and see if there were any variety to his cock. There was n't. He did look to get an erection at the slightest stimulant, but that was fairly typical for a teenage boy with raging hormones. Around ten o'clock, the household retired to their bedrooms for the Night. Donnie had a restless night. He kept dreaming of bare girls parading before him. Every once in a while, his dream would include his female parent and sister among the naked girls.

Donnie came down for breakfast the next dawning and took a whole 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 flair of his Mom's coxa before ? She was wearing a dark knee-length chick and a sheer white blouse that sort of hugged her waist. Her butt curved nicely under that chick. The scheme of her lacy Andrew D. White bra was unmistakable under her sheer white shirt. Was that sexy ? For the first fourth dimension in his lifespan, he thought it was. He could see the gallant of the right side of her boob under her shirt, jiggling as she stirred the flannel-cake mix with a great spoon."holy place 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 veil it from her.

A moment later, Donnie's babe entered the kitchen and took her usual place across the tabular array 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 down eyes. A quick, engaging smile. His sure-enough sister looked different. Her bra strap are visible on her narrow shoulder. And her dummy ? Oh, God, her titty are diminished 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 trimness fiddling pelvic girdle. Her dainty nozzle. Her long, lithe neck. How had he never seen it before ? He tried to smile at her. His cock got uncomfortably hard, and he attempted to acclimate it covertly. His Mom gave him a questioning look. Donnie tried to engage his big sister with small talk about the yearbook she was editing for her college but kept stumbling over his countersign. He finally gave up and excused himself and left for school.

Donnie 's cock had n't made the alteration promised on the internet, so he studied the chemical substance formula and decided that the dosage must bet on organic structure weight. Instead of one teaspoonful of the white pulverization, he put a tablespoon in a cup of hot tea and fuddle it with his dinner. At about two o'clock in the morning time, Donnie woke up. It was still dark outside. He rolled over in his tangle of tabloid 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 bagger underdrawers to examine 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 spicy lump he had ever experienced. He urgently needed to cum. Donnie rushed to his bath, pushed his packer down to his ankle joint, and began to masturbate aggressively. He tightened his hired man around his heavily cock and pounded away. persona of his Mom and sister surged into his head. He seized his prick and increased the musical rhythm. He was harder now than he had ever been in his life. His stopcock was, indeed, a spate to lay eyes on. The head was empurpled and mushroom-shaped. The mineral vein were sticking out and throbbing.

An time of day later, Donnie still hadn't cum. rakehell drained from his head and filled his swollen pecker. He was becoming dizzy, and his arms felt like they were about to lessen off. He'd never experienced anything like it. He waddled over to the bathroom window with his boxers still around his ankle and pulled the window undecided. The cold-blooded, terse air cleared his drumhead. Donnie kicked his boxers off and deposited them in the clothes hamper. Donnie shared a Jack n'Jill toilet with his big sis, 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 sister 's bed, crying because of his painfully gruelling, 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 cock,"he blubbered."It hurts so bad I can't point of view it."

Lucy sat up in her bed and saw that Donnie was nude from the waist down, and his hammer was standing at tending. Lucy had never really given much consideration to her short buddy's cock other than the few times she noticed his foreplay creating a bulge in his gasp.

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

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

"Well, go in the lav and jack-off, or spank your monkey, or whatever the hellhole guy do to make 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 bound and cum, '' Donnie explained to his sister. `` 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 facilitate me cum this one time."

Lucy considered the torment on her little Brother's human face. Her heart went out to him because she could see he was sincerely hurting. Lucy relented and asked her chum to lie on his back. She then crawled between his peg. Lucy set back on her heels and examined Donnie's turncock for a moment. She had seen a lot of cock, but never a dick this tumid. Lucy dated a lot of guys in high school school 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 sentence, Donnie."

Lucy placed both men around her little buddy's cock and felt the nervure and musculus under his cutis. Donnie 's cock twitched and throbbed under his sister 's skilled touch. Lucy first used the 'twist and bend'method, where she would slide both manus up and down his cock while twisting each hand in the opposite direction. Lucy would alternately glide the palm of her hand over the headspring of Donnie 's cock, every third or fourth part stumble to the top of his cock, paying particular attending to his sensitive frenulum.

Both of those approach path 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 explosive orgasm. That technique consisted of gently massaging Donnie's balls with one hand while sliding her other hand up his pulsating tool to his mushroom cloud as she again stimulated the frenulum. While continuing to turn his shaft in that fashion, she tickled his balls with her fingertips. No one had ever lasted More than a few irregular under that method.

As chance would cause it, cypher happened. Lucy fell to her Brother 's position, totally deplete. Her arms were aching, and her fingers were numb.

"Don't plosive speech sound,"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 intend,"Lucy asked ?

Donnie hesitated a recollective bit then gingerly said,"You haven't tried your back talk yet."

Lucy bolted upright in the bed and glared at her little brother. Her facial expression was red, and she could finger the fierce passion rising from her shoulders and neck. Through clenched teeth, she growled, `` You are such a shag degenerate. I am your babe for God's interest ! Sisters don't give their brother blowjob. No way am I going to let you sting that lusus naturae in my mouthpiece !"

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

"Absolutely not,"she growled !

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

Lucy had always had a cutter topographic point in her mettle when it came to her piffling brother. She could never sit by and let him goes through such excruciation and pain without at to the lowest degree trying to relieve his pain. Lucy leaned forward on her custody and knees, opening her oral cavity. In one move, she engulfed his midst cock to halfway. The heat that enveloped his groin was intoxicating. Donnie reached down and gripped the sides of her expression. He watched in astonishment as his sister gave him his get-go blowjob.

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

Donnie shuddered as Lucy swirled her tongue around his raw tip. He thought his chunk were tight, but when her hand came up and cupped his wide sack, Donnie thought he was going to blow right there.

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

'' That 's it, Sis, blow your short brother's peter. '' He groaned.

'' Yuullaakkkkk, '' Lucy tried to tattle as he shoved his dick down her throat.

Donnie felt his balls slap against Lucy's chin as he buried himself in her warm wet back talk, pushing until he felt his cock enter her throat. There was no question of who was in charge now as seven inches of his intemperately cock stretched Lucy's throat with each thrust.

Donnie could take heed Lucy taking breathing spell through her nose, looking down he watched her spit slabber from the corner of her mouth and down her cute piffling mentum. That sight alone was almost enough to defecate him require to blow his load down her throat right then and there, but he didn't want to stop feeling the magnificent pleasance of his babe's mouth just yet.

Lucy's eyes fluttered undefendable, and she stared up into his face. She released her bag on Donnie 's shoulders and slid her hands down his book binding until she gripped a cheek of his ass in each helping hand. She lifted his ass toward her typeface as she forced her mouth down onto his peter until it bumped the back of her throat.

Donnie could n't believe the slut his sister had kept hidden inside. Every one of her calculated movements reeked of sex and lust. When Lucy released Donnie's ass cheeks from her grip, he watched as Lucy's mouth fellate hard around his peak, and then slowly slid down until her nose was buried in his pubic hair. Donnie could feel his cock enter his sister's pharynx again."Fuck, she had just deep throated him again,"he realized.

At the same fourth dimension, Lucy reached up and pulled her nightgown off, and he could only stare at her nude dead body came into aspect. There is nix like having a naked and randy strumpet kneeling between your legs with your cock shoved down her throat, he thought.

Donnie could n't place upright it anymore. Reaching down, he intertwined his finger into her blond hair, holding her head still he began to arch his hip. Donnie could find out her wet slurping as he began to fuck her hot mouth. He thought she might get mad, but instead, she only hummed her approval of him taking dictation. The vibration from her humming went straight to his boiling globe, sending his body into overload and shutting his brainiac down at the same instant.

'' adopt 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 articulatio coxae up harder, driving deeper. He could take heed Lucy start to gag on his length, but she seemed to feed off his motility. Donnie felt his glob slapping against his sister 's spit covered Kuki-Chin. The plenty of his turncock buried down her throat was too much. He was on the sceptre of cumming.

Her mouth suddenly slipped off his pulsating putz, and she began to shiver as her climax raced through her body. Donnie felt the atmospheric pressure ease off his secreter, making his Ball start to settle back down. Lucy was still shaking and convulsing from her orgasm. Donnie clutched her to his chest and pressed his lips to her parched lips. Their spit 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 prick in one hand while he supported himself on the other. Aiming the engorged head to her swollen labia, he lowered his hips. Just as the tip of his shaft touched her moistness, Donnie looked into her centre. He could see the fervour glow in her eyes.

Donnie's cock head parted Lucy's labia like wet petals as he slid the school principal inside, accompanied by a gentle, moist sucking sound. He could feel her pie-eyed silky walls gripping his cock as he pushed deeper.

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

Donnie's dick is the biggest hammer she has ever had in her closely twat, he realized. No marvel her walls felt like a velvet vise, she was as pissed as a virgin against his seven inches. With a grunt, he pushed down, down, down, sliding a couple to a greater extent column inch into her.

He watched as Lucy 's heart fluttered again, her mouth opening in a silent"Oh"as her dead body gave a minor 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 good. '' A small smile crept over her face. `` fucking your big Sister, undecomposed and grueling little brother, '' she urged him.

With only half his prick inside her stiff pussy, Donnie began to rock his rose hip, slowly sliding in and out of her now dripping pussy. With each forward motion, he slipped more and more of his duration inside her.

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

'' Do n't displace for a secondment, '' Lucy gasped."Let me do the employment for a while."

He could feel her rosehip grind in a slow circle under him as her genus Venus mound pressed against his pelvis. There were rhythmic like wafture pulsing along her tight paries 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 eyes slowly rolled back again.

'' Ooohhhhhhhh '' Lucy softly whimpered as her stallion consistency jerked under her little brother. She stopped moving as a torrent of fluids gushed out to soak Donnie's shaft and balls, and then slowly run down the shot of Lucy's ass to drench the shroud under her.

'' Wow, '' Lucy whispered as her eyes refocused on Donnie's boldness. `` Are you sure you were a virgin, little comrade ? '' 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 sleep together me. ``

Donnie pulled slowly back until just the head of his turncock rested inside her wet opening. Hovering over her, Donnie locked eyes with his sister. Donnie gave a silent thanks to hours of watching porno that had prepared him to recognize what to do to please his beautiful baby sexually.

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

Donnie then rammed his tool down hard, slicing down through her velvet walls, driving rich, rich, deep. Lucy's legs shot out and then wrapped around her brother's waist as she scrapped her nails painfully down his back. He felt another effusion 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 hips rose and fell as he pounded down into her with unrestraint. One vantage to her brother was an almost unlimited energy supply supplemented by the chemical intermixture that kept his prick unusually gruelling. Wet slurping filled the way, as the perfume of their sex hung heavy in the air.

'' nooky me ... hump me ... '' Lucy chanted as her piffling sidekick, hammered into her. `` Own me, trivial chum, '' she said. `` I 'm yours for the taking. ``

Donnie knew he would n't last much longer. It would be a welcome relief to his aching balls, but he did n't desire the delight of his stopcock sliding in and out of his baby to ever end. Donnie could hear his balls slapping his sis's cum soaked ass as he fucked into her with everything he had.

'' Oh, My Fucking God, '' Lucy's eye grew immense. `` Again ... oh screwing ... oh God ... '' Lucy gasped.

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

'' My little Brother is making me cum so do it 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 babe orgasm a fifth time, his body gave in to the genius as his balls started to tighten. Lucy gasped, her eyes locking to his. Donnie tried to keep looking into her oculus as his climax hit, honestly, but it was n't going to fall out. Donnie's center rolled back in his head as his released cum exploded from his Ball and shot the length of his cock.

'' Oooohhh, '' Lucy gave a primeval holler as the first flak jetted out to lap her spasming walls.

Donnie refocused on Lucy's face as topper he could as his ass cheeks tightened, and a sec flare-up pumped out to oversupply her waiting pussy. He could see the look of wonder in her eyes.

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

By the clock time the last spasm of his cock hit, it had to be three or four hot circle he had let on the loose inside her. Donnie rocked back on his hound between Lucy's lewdly spread second joint, looking down between their joined bodies.

The erotic sight of his cock sliding from her tight pussycat was exciting enough. Still, the additional image of White person chunk of ointment that matted both their pubic tomentum, as their miscellaneous cream 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 breast. `` Now, my BIG footling sidekick is a man. '' She said.

As Donnie slid his cock free of Lucy's clutching kitty-cat, he was thrilled to see it coated with their slick goo, and his orb no longer ached and throbbed. He was even more excited to realize that after emptying his balls, he was still rock hard. He wanted to a greater extent of his sister, and he intended to have her.

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

'' Forever piffling Brother, '' Lucy whispered back.

Donnie reached down and began to roll Lucy onto her stomach. Pulling up on her rose hip, she rose to her hands and knee on the bed. She looked over her articulatio humeri at him as he positioned himself behind her. There was a fire in her centre he had never seen before.

'' Are you going to hop on me ? '' Lucy growled. `` Are you going to screw your big Sister like a bitch in heat ? ``

Donnie snarled with lecherousness as he dragged the puff up mind of his tool along with his sister 's cum soaked lips. He never had in his life heard his sister public lecture like that ; it was as if she had become the loose woman he'd dreamed about.

'' I fucking hump this position, '' Lucy moaned. `` It 's been too tenacious since I was so satisfied ; now fuck me like the prostitute I am. Every maw I have belongs to you now, little blood brother. ``

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 bang some of your sorority sisters the next fourth dimension I get hard like this ?"

"Donnie ! I'm your SISTER ! I get first dibbed on your marvellous peter ! ”
