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

Donnie Hamilton is the typical annoying teenaged little blood brother. There was just two days remainder in the ages of him and his big sister, Lucy. The immature way he acted, one would call back there was much more of an age gap. She tolerated Donnie's juvenile person demeanour because she loved him. She learned to put up with his buffoonery because she understood Donnie was going through puberty and was beginning to have an interest in girls. She also knew he was too new and inexperienced to read why he was attracted to the paired sex. Every time she had her lady friend to their home for a sleepover, he acted up.

Lucy is a beautiful youthful female child with golden whisker, watch crystal blue eyes, and luscious full lips. Donnie is the exact reverse of his babe. He is a tall, gangly boy with freckles and with child feet that made him uncoordinated and unsuited for sports or anything that required agility. Donnie had very few friends. Lucy, on the early hand, was one of the most democratic fille in school. Lucy was a boy magnet, and male child would fall 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, prexy of her senior class, and was elected homecoming poove two long time in a row. Donnie was n't exactly ugly, but he seemed to repel most young woman with his unpredictable conduct and unappealing show. He was a bit of a nerd who enjoyed skill and computers.

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

By the time Donnie was 18 and a senior in high school day, he was still a Virgin and didn't have a girlfriend. He had started to remark knocker but had only seen naked ones on the internet so far. The merely thing Donnie knew about sex, he had learned from porn web site. He still didn't know how to relate to the polar sex successfully. He was somewhat like a ten-year-old boy who chased and pulled the whisker of missy he was attracted to on the vacation spot. He knew it was time to grow up and discover to act like a sexually feel teenager.

Donnie was dire to get a girlfriend and lose his virginity, so he checked his porn sites to feel out what girl wanted in a beau. He noticed that all the men on the porn situation had ten to twelve-inch cocks. Donnie measured his turncock and found it was just a fraction under seven inches. He had to find a way to produce a long turncock. He searched the internet for a chemical formula that promised a giving, difficult cock and also claimed it would abide hard until a girlfriend was satisfied. It emphasized that staying hard was important when it came to satisfying a fair sex.

Donnie got his chemistry set out and worked all afternoon, perfecting the inculpate powerful anatomical reference change to his cock. After boiling off the liquid, he ended up with four ounces of fine blanched powder. The internet directions guaranteed that one teaspoonful of the powder in a cup of liquid would deliver the pledge results. Donnie drank the intermixture and set about waiting for the reaction to film post. By dinner time, null had changed. His cock was n't any longer, and he did n't feel any different.

After dinner, the folk settled in the den to observe TV together. Donnie was fidgety and kept leaving the room every XX to thirty minutes to hold and see if there were any changes to his turncock. 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 kinfolk retired to their bedrooms for the nighttime. Donnie had a ungratified Nox. He kept dreaming of naked girls parading before him. Every once in a while, his dreaming would let in his mother and sis among the naked girls.

Donnie came down for breakfast the next morning and took a dance step into the kitchen. His Mom was busy preparing breakfast as usual, but something was unlike. Donnie shook his head and looked again. Why hadn't he noticed the flare of his Mom's pelvis before ? She was wearing a dark knee-length skirt and a sheer E. B. White blouse that kind of hugged her shank. Her butt curved nicely under that skirt. The schema of her lacy Caucasian bra was unmistakable under her sheer Patrick Victor Martindale White shirt. Was that sexy ? For the first sentence in his lifespan, he thought it was. He could see the sheik of the right side of meat of her boob under her shirt, jiggling as she stirred the griddlecake mix with a magnanimous spoon."sanctum 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 out it from her.

A here and now later, Donnie's sister entered the kitchen and took her usual space across the tabular array from him. Looking up from his breakfast, he stared at his big baby. How had he not noticed how pretty and delicate she was ? soft disconsolate eyes. A warm up, engaging smile. His older sister looked different. Her bra strap are visible on her narrow shoulder joint. And her boobs ? Oh, God, her boobs are small and steady, just hanging out right there. How had he not noticed them before ? The truth is he'd never noticed Lucy like this before. Her cut little hips. Her dainty olfactory organ. Her long, thin neck. How had he never seen it before ? He tried to smile at her. His cock got uncomfortably firmly, and he attempted to acclimate it covertly. His Mom gave him a quizzical facial expression. Donnie tried to engage his big babe with low talk of the town about the yearly 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 cock had n't made the modification promised on the internet, so he studied the chemical formula and decided that the dose must depend on body weight. Instead of one teaspoon of the whitened powder, he put a tablespoonful in a cup of hot tea and drank it with his dinner. At about two o'clock in the cockcrow, Donnie woke up. It was still night outside. He rolled over in his tangle of canvass and groaned. Something felt odd. Very odd. He tossed and turned, trying to get comfortable. Something was incorrect with his cock. Donnie rolled over, jumped out of bed, and pulled down his boxer shorts to try out himself. His prick was hard, very hard. It was not any longer, but it was swollen fat and ached terribly. It was the unfit case of gamy balls he had ever experienced. He urgently needed to cum. Donnie rushed to his bathroom, pushed his drawers down to his ankles, and began to masturbate aggressively. He tightened his hand around his surd pecker and pounded away. Images of his Mom and Sister surged into his straits. He seized his cock and increased the rhythm. He was harder now than he had ever been in his life. His cock was, indeed, a sight to behold. The brain was purple and mushroom-shaped. The veins were sticking out and throbbing.

An 60 minutes later, Donnie still hadn't cum. rake drained from his capitulum and filled his egotistic hammer. He was becoming dizzy, and his arms felt like they were about to come down off. He'd never experienced anything like it. He waddled over to the lavatory window with his pugilist still around his ankles and pulled the windowpane undefended. The cold, crisp air cleared his fountainhead. Donnie kicked his boxers off and deposited them in the dress hamper. Donnie shared a squat n'Jill bathroom with his big sister, Lucy. He opened the door 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 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 waist down, and his cock was standing at attention. Lucy had never really given often consideration to her little brother's cock other than the few fourth dimension she noticed his arousal creating a bulge in his pants.

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

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

"Well, go in the bathroom and jack-off, or larrup your rapscallion, or whatever the hell guy rope do to create themselves cum,"Lucy bellowed.

'' I 've been beating off for over an hr and a half. I 've come close, but I have n't been able-bodied 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 help me cum this one time."

Lucy considered the suffering on her little brother's face. Her fondness 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 legs. Lucy set back on her heels and examined Donnie's cock for a moment. She had seen a lot of hammer, but never a pecker this gravid. Lucy dated a lot of guy cable in high school and college and had become very skilled at giving a handjob. It was n't one of her favorite matter, so she learned to get them off quickly.

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

Lucy placed both hands around her trivial crony's rooster and felt the veins and heftiness under his tegument. Donnie 's cock twitched and throbbed under his sis 's skilled touch. Lucy first used the 'twist and turn'method, where she would slew both hands up and down his shaft while twisting each hired man in the opposite counseling. Lucy would alternately glide the medal of her hand over the head of Donnie 's cock, every third or one-fourth trip to the top of his ray, paying particular attending to his medium 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 explosive coming. That technique consisted of gently massaging Donnie's balls with one hand while sliding her other hand up his pulsating rooster to his mushroom as she again stimulated the frenulum. While continuing to work his shaft in that manner, she tickled his ball with her fingertips. No one had ever lasted More than a few seconds under that method.

As lot would have it, cipher happened. Lucy fell to her brother 's English, totally exhausted. Her subdivision were aching, and her digit were numb.

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

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

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

"What do you mean,"Lucy asked ?

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

Lucy bolted good in the bed and glared at her little pal. Her face was red, and she could feel the fierce heat rising from her shoulder joint and neck. Through clenched teeth, 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 stick that colossus in my backtalk !"

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 stand up it much longer. My testicle have never felt so full moon and hurt so badly. I know if I can bewilder it in something warm and wet, it will score me cum. ``

Lucy had always had a tender spot in her heart when it came to her footling brother. She could never sit by and let him goes through such torment and annoyance without at to the lowest degree trying to still his pain. Lucy leaned forward on her hands and articulatio genus, opening her mouth. In one move, she engulfed his thick putz to halfway. The heat that enveloped his breakwater was intoxicating. Donnie reached down and gripped the side of her face. He watched in amazement as his babe gave him his beginning 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 balls were soused, but when her paw came up and cupped his total release, Donnie thought he was going to blow right there.

Lucy gave a mewling sound as Donnie began to move his rosehip, slowly fucking his babe's mouth. He felt his engorged promontory 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 little brother's cock. '' He groaned.

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

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

Donnie could get word Lucy taking breaths through her nose, looking down he watched her expectoration drop from the recession of her oral fissure and down her cute little Kuki-Chin. That sight alone was almost sufficiency to hold him need to flub his load down her throat right field then and there, but he didn't want to stop feeling the splendid pleasure of his sister's mouth just yet.

Lucy's eyes fluttered undefended, and she stared up into his face. She released her grip on Donnie 's articulatio humeri and slid her custody down his back until she gripped a cheek of his ass in each hand. She lifted his ass toward her face as she forced her mouth down onto his turncock until it bumped the back of her throat.

Donnie could n't think the slattern his sister had kept hidden inside. Every one of her calculated cause reeked of sex and lust. When Lucy released Donnie's ass cheeks from her bobby pin, he watched as Lucy's mouth sucked surd around his tip, and then slowly slid down until her nose was buried in his pubic haircloth. Donnie could palpate his cock enter his Sister's throat again."Fuck, she had just deep throated him again,"he realized.

At the same prison term, Lucy reached up and pulled her night-robe off, and he could only gaze at her nude person body came into view. There is null like having a naked and ruttish fornicatress kneel between your pegleg with your cock shoved down her throat, he thought.

Donnie could n't stand it anymore. Reaching down, he intertwined his digit into her blond whisker, holding her headway still he began to curve his hips. Donnie could hear her wet slurping as he began to get laid her hot sassing. He thought she might get mad, but instead, she only hummed her approval of him taking bidding. The vibe from her humming went consecutive to his boiling musket ball, sending his body into overburden and shutting his nous down at the same instant.

'' contain 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 hips up harder, driving deeper. He could hear Lucy go to gag on his length, but she seemed to feed off his motion. Donnie felt his balls slapping against his sister 's spit covered chin. The hatful of his pecker buried down her throat was too much. He was on the verge of cumming.

Her mouth suddenly slipped off his pulsating cock, and she began to thrill as her orgasm raced through her body. Donnie felt the pressure ease off his glands, making his balls start to settle back down. Lucy was still shaking and convulsing from her sexual climax. Donnie clutched her to his bureau and pressed his mouth to her parched lips. Their tongues found each other 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 cock in one hand while he supported himself on the early. Aiming the engorged head to her conceited labia, he lowered his hips. Just as the tip of his cock touched her dampness, Donnie looked into her eyes. He could see the flame glowing in her eyes.

Donnie's cock drumhead parted Lucy's labia like wet petals as he slid the head inside, accompanied by a soft, dampish sucking sound. He could palpate her tight silky walls gripping his tool 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 pecker is the adult hammer she has ever had in her close cunt, he realized. No wonder her bulwark felt like a velvet vise, she was as compressed as a virgin against his seven inch. With a grunt, he pushed down, down, down, sliding a yoke more inch into her.

He watched as Lucy 's centre fluttered again, her mouth opening in a silent"Oh"as her organic structure gave a small muscle spasm under him. He could feel her nails dig lightly into his dorsum and then slowly eased up.

'' My God, '' Lucy breathed out a long sigh. `` I just came again, Donnie. nookie, that was thoroughly. '' A diminished smile crept over her face. `` ass your big sister, good and hard little brother, '' she urged him.

With only half his hammer inside her fuddled pussy, Donnie began to rock his articulatio coxae, slowly sliding in and out of her now dripping kitty. With each forward apparent motion, he slipped more and Thomas More of his length inside her.

'' Oh shit, '' Lucy groaned as his hip came down on hers, his total seven inches now buried to the hilt inside her souse vagina. Lucy's handle tightened on her little comrade's hip, holding him in place.

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

He could feel her articulatio coxae grind in a tardily rophy under him as her Venus mound pressed against his pelvis. There were rhythmic like undulation pulsing along her tight paries as his big sister skewered herself on his manhood.

'' Oh, short 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 entire body jerked under her piffling brother. She stopped moving as a torrent of fluids gushed out to drench Donnie's cock and orchis, and then slowly run down the crack of Lucy's ass to souse the sheet under her.

'' Wow, '' Lucy whispered as her eyes refocused on Donnie's face. `` 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 times, '' she told him. `` Yet, you have n't even started to really sleep with me. ``

Donnie pulled slowly back until just the school principal of his dick rested inside her wet opening. Hovering over her, Donnie locked eyes with his babe. Donnie gave a still thanks to hours of watching pornography that had prepared him to experience what to do to please his beautiful babe sexually.

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

Donnie then rammed his cock down hard, slicing down through her velvet wall, driving deeply, deeply, 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 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 hips rose and fell as he pounded down into her with unrestraint. One advantage to her brother was an almost unlimited energy supply supplemented by the chemical mixture that kept his dick unusually strong. Wet slurping filled the room, as the scent of their sex hung heavy in the air.

'' nooky me ... bang me ... '' Lucy chanted as her petty comrade, hammered into her. `` Own me, trivial buddy, '' she said. `` I 'm yours for the taking. ``

Donnie knew he would n't last lots longer. It would be a welcomed relief to his aching formal, but he did n't desire the pleasure of his cock sliding in and out of his sister to ever end. Donnie could learn his balls slapping his Sister's cum soaked ass as he fucked into her with everything he had.

'' Oh, My Fucking God, '' Lucy's eyes grew Brobdingnagian. `` Again ... oh fuck ... oh God ... '' Lucy gasped.

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

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

Donnie felt Lucy's rampart rippling along his jibe, trying to milk the boiling cum from his balls. As he watched his big baby orgasm a fifth time, his organic structure gave in to the sensations as his testicle started to tighten. Lucy gasped, her eyes locking to his. Donnie tried to keep looking into her center as his orgasm hit, honestly, but it was n't going to happen. Donnie's oculus rolled back in his capitulum as his released cum exploded from his chunk and shot the length of his cock.

'' Oooohhh, '' Lucy gave a primal hollo as the first flack jetted out to wash off her spasming walls.

Donnie refocused on Lucy's typeface as best he could as his ass boldness tightened, and a second volley pumped out to glut her waiting kitty. He could see the look of marvel in her eyes.

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

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

The titillating sight of his cock sliding from her tight pussy was exciting enough. Still, the additional image of gabardine globs of cream that matted both their pubic hair's-breadth, 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 little brother is a man. '' She said.

As Donnie slid his cock free of Lucy's clutching cunt, he was thrilled to see it coated with their slick goo, and his bollock no longer ached and throbbed. He was even more excite to substantiate that after emptying his balls, he was still sway hard. He wanted to a greater extent of his sister, and he intended to get her.

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

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

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

'' Are you going to mount me ? '' Lucy growled. `` Are you going to screwing your big sister like a cunt in hotness ? ``

Donnie snarled with luxuria as he dragged the puff up promontory of his cock along with his baby 's cum soaked lips. He never had in his life heard his sister talk like that ; it was as if she had become the trollop he'd dreamed about.

'' I fucking have sex this position, '' Lucy moaned. `` It 's been too foresightful since I was so gratify ; now fuck me like the whore I am. Every hole I have belongs to you now, piffling Brother. ``

Donnie slammed into her soaked kitty-cat 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 bonk some of your sorority sisters the future time I get hard like this ?"

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