Lynn Loud was competitive to the max. She wanted to be the biggest, the fastest, and the strongest at all times. If someone came along who was even slightly better, she would push herself to the limit like Scarface and beat them, even if it took her six months. She was on every sports team Royal County Middle had to offer and turned everything into a competition. If she and Luan were folding laundry, she would declare a race and then fold ten shirts in the time it took most people to fold two. When she inevitably won (because she was the best), she would pump her fist and scream BOOO-YAAAAAH. If she lost, she'd tear her room down and mope on her bed for six hours beating herself up for letting herself be beaten. Because that's the only way she could take an L: If she let herself.

In addition to being competitive, she was also kind of jealous. If you had something and she didn't, she'd get salty about it. She didn't resent rich people for having helicopters or anything because, you know, out of sight, out of mind, but if, say, someone gave Lola a Popscile and not her, well fuck you, I want that Popscile. As a little girl, she used to steal toys from Lucy and Luan not because she wanted to play with them, but because she wanted them. Why did she want them? Because Lucy and Luan had them, duh.

She wasn't quite as bad now that she was almost fourteen, but there were times when that old green eye monster reared its ugly head. When Luan won tickets to a comedy club from the radio, Lynn insisted that she get one of them even though she didn't like comedy, she just didn't want to be left out.

All of these things combined to create the perfect storm of pettiness, and if Lynn wanted to, she could use it to fuel herself in pursuit of any task.

Just such a pursuit began on one hot summer day in late June. Lynn was sitting on the kitchen counter in socks and an oversized T-shirt and eating a granola bar when Lincoln jogged in. He was wearing an orange tank top, dark blue shorts, and a headband. He stopped, jogged in place, and blew puffs of air. His face was red and sweaty and Lynn noticed that his arms and legs were far more toned than they had been just a few weeks ago. He stopped jogging and started to do jumping jacks.

"What's with you?" she asked, suddenly suspicious.

"I love exercising," he panted.

About a month ago, Lincoln, whose life consisted of video games, comics, and being a lazy fuck, randomly started working out. He jogged every morning, did calestertics before school, and went with Luan to the YMCA and to Maggie's house. The change was sudden and rapid. He went from being a couch potato to a gym rat in under thirty days.

Kind of fishy, if you asked Lynn.

"Why?" she demanded.

Lincoln dropped to the floor and began doing push-ups. "Because I love the burn," he said.

Hmmm, okay, well, the burn was nice, and there was no greater feeling than the pleasant weariness that comes at the end of a long, active day, but still. Lincoln used to scoff at the idea of working out, now he was turning into a frickin' musclehead.

Sus as fuck.

Jumping to his feet, Lincoln went back to jogging in place. Luan, dressed in a similar outfit, jogged in and ran literal circles around him. "Ready, Linc?" she asked.

"Sure am."

They jogged out.

"Where are you going?" Lynn called.

"Maggie's!" Lincoln responded.

Maybe Lynn was being paranoid, but she was certain something weird was going on here.

And she was going to find out what it was.

Hopping off the counter, she ran upstairs, threw her bedroom door open, and walked in on Lucy holding a seance with a bunch of Lola's stuffed animals. "You're disturbing the spirits," Lucy deadpanned.

"You disturb me," Lynn shot back. She went to her dresser, pulled out a pair of underwear, and slipped them on. She took her shirt off and tossed it away, then grabbed a new one, her powerful back muscles flexing and straining and her tiny breasts lifting as she put it on. She yanked on a pair of socks, stepped into her shoes, and raced down the stairs, jumping off the fifth one up and sticking the perfect landing. Outside, the morning was already hot and dry, and the only sound was the rattle and hum from A/C units up and down the street. Lynn hopped on her bike, pushed off, and hung a left at the sidewalk. She ducked her head to avoid hitting some low hanging branches and crossed the street two blocks up. Furnace wind blew against her face like sandpaper and a bug flew into her mouth, making her gag. The bike wobbled and she wrenched the handle bars, overcorrecting and hitting a tree. She fell off, landed on a root, and cried out in pain.

Stupid fucking bike.

Stupid fucking tree.

She got up, climbed back on, and rode the rest of the way to Maggie's house with her lips pursed so nothing else got in.

When she finally reached Maggiie's house a few minutes later, Lynn leaned her bike against the tree out front and went up to the door at a crouch. There was an oval shaped window set in the middle but it was frosted and she couldn't see through it. She went around to one side and peered through a window looking into what appeared to be a guest room. She went to another window, but all she saw beyond was a bathroom.

In the backyard, she dropped to her hands and knees and commando crawled to the porch. She slithered up the stairs, pressed her back to the wall beneath the picture window, and shuffled until she was right in the middle; all she had to do was raise her head and look over the sill. She listened and could hear muffled talking; it sounded like Luan's voice.

Getting to her knees and gripping the sill, Lynn raised her head.

What she saw gobsmacked her.

Luan and Maggie were both bent over with their fingers touching their toes and the thong straps of their one piece leotards pushed to the side revealing their moist, pink centers. Lincoln, shorts around his ankles, stuck his dick into Maggie, and then into Luan. "One and two and three and thrust," Luan said, and her eyes rolled when he jammed himself into her. Lynn's jaw dropped and she gaped at the scene unfolding before her. At first, she was utterly sickened. Like, okay, he's fucking Maggie, whatever, but Luan too? Gross! The more she studied her sister's face, examining closely the way it twisted and contorted in pleasure, the more she started to feel, well, jealous. From the faces Luan was making, it looked like getting by Lincoln felt really good.

Why should Luan get to feel good while she, Lynn, didn't? Look at Lincoln spraying his cum all over Luan's butt and acting like his soul was coming out. What was so great about Luan? She could work his dick with her pussy waaaay better. He was shaking, gritting his teeth, and rolling his eyes like Luan was the greatest thing ever, but he didn't know shit about the greatest thing ever. He was fucking medicority. Both Maggie and Luan barely moved the whole time, they let him do all the work. If it was her in there, she'd do the splits all over his dick and bounce like a fucking rabbit. That boy would be worn out by the time she was done with him. And there'd be none of this pulling out nonsense. He wouldn't be able to control himself inside of her wetness.

You know what? Fuck this. She was gonna steal Lincoln away from those two dykes. If he liked working out so much, she'd give him the work out of a lifetime. The fact that he was her brother was entirely irrelevant now. He could be six hundred pounds and have one ball, it didn't matter; he was a prize like any other and she was going to win it.

Leaving Maggie to clean hers, Lincoln's, and Luan's splooge from her living room carpet, Lynn jumped on her bike and raced back home. She stopped at the drugstore for some Plan B for after Lincoln nutted in her, and on the way out she passed someone plastering a poster to the outside of the window. She stopped to look…

And for the second time in less than half an hour, her jaw dropped.

The poster was an ad for the YMCA. it featured a girl looking over her shoulder and grinning slyly. She wore a one piece leotard, leg warmers...and a big red nose. Our summer discount is no joke, the caption read.

And the girl?

It was Luan.

Like Fred Sanford faking a heart attack, Lynn clutched her chest and stumbled back. They put Luan on a poster for the freaking YMCA? LUAN WAS THE LITERAL POSTER CHILD FOR WORKING OUT? What kind of crazy, coked-up world was this? Luan must have sucked the right dick at the right time because there was no other way she could have gotten that spot.

Lynn's eyes narrowed.

Oh, you are going down, Luan.

Just like you did to get on that poster, you little cunt.

That night, when Luan and Lincoln got home from Maggie's house, still red and sweaty from their "workout", Luan went into her bedroom and found Lynn doing push-ups in the middle of the floor. The little jock wore a pair of red shorts and a white T-shirt so damp with sweat that it clung to her rose bud breasts. She was not wearing a bra, and if you looked closely, you could see the dark outline of her areolas. "3.065...3,066…"

Luan cocked her brow. "What are you doing in here?" she asked.

Getting shakily to her feet, Lynn brushed her sodden hair out of her face and favored her older sister with a mad grin. "I know what you and Lincoln do at Maggie's house."

The color drained from Luan's face. "What do you mean?"

"You know what I mean," Lynn said. She balled her hands to the side of her face and batted her eyelashes. "One and two and three and thrust."

Luan swallowed hard. "I don't know what you're talking about."

"Cut the shit, bitch," Lynn said. "I know you're fucking our brother and I know they put you on that YMCA poster. Well, guess what. I'm going to take both of those things away from you because fuck you, they belong to me now."

Realizing what Lynn was saying, Luan stiffened. "Are you now?" she asked.

Lynn nodded. "Oh, yeah. I'm better at exercising than you. And I'm gonna be better at rocking Lincoln's world. Give it one week, and he'll choose me over you and that pale lil goff girlfriend of yours."

A shadow flickered across Luan's face and her lips peeled back from her teeth. She jabbed Lynn's chest and pressed their noses together. "You're on."

Lynn shoved past Luan and went to the door. "Be ready to lose everything."

"You're the one who's gonna lose," Luan said. "You think you're so great but you're mediocre at best."

"We'll see about that," Lynn said. She turned and left the room, her hands balling into fists at her sides. As it just so happened, Lincoln chose that exact moment to appear at the top of the stairs. Lynn honed in on him like a heat seeking missile. "Yo, Linc!"

Lincoln looked at her. "Hey, Lynn."

Lynn grinned. "So you're into exercising now, huh? I got some cool exercises we can do. They're waaay better than whatever weak ass shit you do with Luan and Maggie."

Crimson colored Lincoln's cheeks and his eyes darted away. "I dunno," he said, "our routine is pretty great."

"Mine's better," Lynn said. "We start tomorrow." She punched him in the arm and he hissed in pain. "Get plenty of rest. You're gonna need it."

She could feel Luan watching them.

Watch how it's done.

The competition began the next morning. Lynn dragged Lincoln out of bed at 6am and led him on a jog through the still, early morning streets of Royal Woods. She slowed her pace to match his and said, "I got something cool planned for later on."

Lincoln looked nervous. "Well, I'm gonna hang out with Clyde later, so -"

"Not anymore you're not," Lynn said. "We got lots of training to do."

Back at the house, everyone was still asleep and silence ruled. In the kitchen, Lynn whipped up two shakes consisting of spinach and raw eggs. She handed one to Lincoln and drank the other. Lincoln hesitated, and seeing his reluctance, Lynn said, "Go on, Linc." She caught a bit of runny egg yolk on her curled tongue, and looking Lincoln right in the eyes, she seductively licked her lips.

He chugged his drink.

Done with that, they retreated to the basement where Lincoln donned big padded gloves that Lynn proceeded to kick with bare feet. "This helps with developing muscles in your legs," she said. "My thighs are so strong they could crack your skull."

Lincoln uttered a nervous laugh.

"Don't believe me?" she asked.

"No, I -"

Grabbing Lincoln by the shoulders, she jammed her foot behind his and wrestled him to the ground. She wrapped her legs around his head and pinned him between her thighs. His cowlick ghosted across her crotch and stimulated her through her shorts. Lincoln kicked and flailed, and the vibrations of him struggling for his life made her heart race. She began to hump the back of his skull and he fought even harder. If this kept up for a couple minutes, she could probably cum.

Before she could get there, Luan came in and glared at her. Lynn stopped in mid-thrust and shot her older sister daggers. "What do you want, Metalface?"

Ignoring her, Luan turned her attention to Lincoln. "We're going to the Y."

Lincoln broke Lynn's hold and jumped to his feet. "Awesome," he said. His tone was a little too excited for Lynn's liking.

"I'll come with," she said and got up.

"Sorry, but my special discount only covers one friend, so I'm taking someone I actually like." She pinched Lincoln's butt and he jumped.

'Don't worry, Chuckles," Lynn said, "I can pay my own way."

"Why don't you pay it in the other direction?"

Lynn stepped up and Luan met her in the middle. Before things could get gory, Lincoln stepped between. "Hey," he said, "are we going or not."

"Yes," Luan said, "we are."

"I'll be there with bells on," Lynn said.

"Put on deodorant instead."

Lynn growled.

By the time Lynn got her gym bag ready, Lincoln and Luan were already gone. She hopped on her bike and made breakneck speed toward the Y, getting there just as Lincoln and Luan went inside. Lynn chained her bike to the bike rack and went inside. She stowed her stuff in a locker and ran to catch up with Lincoln and Luan.

She found them in the main workout room in the center of the building. Weight machines, ellipticals, and treadmills filled the space. Lincoln and Luan were jogging side by side on the treadmills, and Lynn went over, taking the one next to Lincoln. "I thought I smelled oniony armpits," Luan said.

"That's just Maggie lingering on your upper lip," Lynn retorted.

Luan's nostrils flared and Lincoln looked uncomfortable. Lynn faced forward and watched Luan from the corner of her eye. Was Luan's treadmill really on the lowest setting? And to think they put her on their posters. She increased the speed of her own treadmill by three and the belt whirred beneath her feet. Luan glanced at her, frowned, and turned the speed of her treadmill up by four. Not to be outdone, Lynn turned hers up again and Luan did the same. Now they were both maxed out and running as fast as they could to keep from being thrown off. Their machines shook and moaned, the low thunk, thunk, thunk of the belts slapping plastic keeping steady pace with the beating of their hearts. Lynn panted for air and pumped her arms. There was no room for error; even the slightest misstep would send her falling. Luan did the same, face red and chest heaving. She looked like she was going to break any minute, all Lynn needed to do was keep it up for a few minutes longer.

Lincoln looked between them and knitted his brow. "You guys should slow it down a little."

"Shut up, Lincoln," they said in unison.

"Fine," he said defensively. "Whatever."

Lynn's legs were burning and her lungs heaved. A hot stitch flared in her side and she gritted her teeth. Just...a...few...more…

Finally, Luan stumbled and went down, the machine instantly throwing her off and into the wall behind them. Lynn laughed, and that momentary loss of focus was enough to do her in. Her feet went out from under her and she hit the belt face first. It slung her off and she crashed into the wall butt first. Pain streaked up her tailbone and she slumped over to the side, as close to dead as she'd come in a long time. Lincoln turned his machine off and rushed over. "Are you guys okay?" he asked.

"She's not," Luan said and got to her feet. Her legs quivered and she only kept her balance by holding onto the wall-mounted handrail.

Lynn pushed herself to her hands and knees, caught her breath, and stood. "I've never been better." To prove it, she went to a leg machine, added two hundred pounds, and started to lift. Luan hopped onto a stationary bike, leaned over the handlebars, and pedals so fast that her legs turned into a cartoonish blur. Lynn curled a 20 pound dumbbell, Luan moved to the pull down machine, adding so much weight that she could barely move it, and Lincoln just stood there, watching them with a puzzled look. They went from one machine to the next, shoving people out of their way, and tried to out do the other. A small crowd of people gathered around, including YMCA staff, and Lincoln heard someone say, "Hey, it's the clown from the poster."

"I'm a waaaay better choice," Lynn said. "Watch, I'll prove it."

A moment later: "OW, MY GLUTE!"

Next, they wound up side by side on the floor locked in a no holds barred push up contest. They both started strong but ran out of gas fairly quickly. Luan's arms wobbled and Lynn's face clutched in agony. "I love the burn," she said through her teeth, more to convince herself than anyone else. The crowd grew as people came from the pool, basketball court, and even the street to watch. People placed bets, cheered their favorite Loud, and talked in excited tones. "I love watching teenage girls exercise," a sweaty fat man said.

"I just love watching teenage girls," a leering, weasel-faced chomo said.

Luan face planted, and Lynn followed suit a moment later. Lynn's fans cheered and Luan's booed. Money changed hands and a couple YMCA employees helped the girls to their feet. "This isn't over," Luan said to Lynn. "I'll see you in the pool."

Ten minutes later, close to two hundred people packed into the pool area to watch Lynn and Luan race. Luan came out of the women's locker room in a tight yellow one piece and the crowd went wild. She stuck out her butt and batted her eyelashes over her shoulder in imitation of her image on the poster. Grown men cat-called and a male Y employee whistled. She went over to the edge of the pool and mimed diving.

Lynn came out, clad in a two piece bikini and pumping her fist, and everyone lost it, their raucous cheers resounding in the vaulted eaves. "Take it off!" someone yelled. Standing off to the side, Lincoln feasted his eyes on their butts, boobs, and silky skin. His dick stirred in his pants and he had to bend slightly forward at the waist to hide his growing erection.

A female Y employee blew a whistle and Lynn and Luan dove head first into the water. Lynn's form was better but Luan was quicker; the shot through the water like an amber-headed torpedo. Everyone sat forward in their seats with bated breath, waiting for her inevitable win.

At the last minute, Lynn streaked past her and snatched victory from the jaws of defeat. The audience went wild; their cheering was so loud that Lincoln winced and had to plug his ears. Luan glared at Lynn and Lynn shot her a smug little smirk.

The final competition was a one on one basketball game in which Lynn had all the advantages. The winner would be declared the new poster child for the YMCA. They met on the court as a full house of onlookers watched. Lincoln didn't know how many people were on the sidelines, but he was certain that it was more than had ever been inside the Y at one time before.

Despite not being well-versed in sports, Luan put up a good fight, managing to get the ball away from Lynn fairly consistently and making just as many shots as she missed. Two minutes before the buzzer ran out, Luan was down by three points. At best, she could tie the game; at worst, lose and lose the whole day as well.

Dribbling the ball, Luan ran down the court, the soles of her shoes scuffing on the polished wood as she danced around Lynn. Lynn got the ball away and everyone sucked a deep intake of breath. Luan gave chase, and right before Lynn could set up her shot, Luan got the ball and started making for the basket. The electronic counter on the wall ticked down the seconds. 10...09...08...07.

Luan stumbled and almost fell. She was too far away from the basket to make an easy shot and didn't have time to get any closer, so bending her knees, she jumped up and shot the ball. It arched through the air like a cannonball tearing through a field of battle. The gym was so quiet that you could hear pin drop.

The ball hit the rim, spun around like a turd in a toilet bowl, and then, just as the buzzer sounded, it dropped in. The audience exploded and surged onto the court. Lynn rolled her eyes and stuck out her hand; Luan took it and they shook. "I guess you're as good as me," Lynn said, "for now."

A man in a white polo shirt with the YMCA logo on the chest came over. "You girls did a tremendous job today. We haven't been this full in years and membership registration has increased tenfold."

"Who's the winner, though?" Lynn asked.

"Yeah," Luan echoed.

The man beamed. "Both of you."

A half an hour later, a new poster was taped up in the front window. On it, Lynn and Luan both looked sexily over their shoulders, their hands clutching each other's butts. The YMCA: Fun for the Whole Family. They stood proudly on either side of Lincoln and stared up at the poster with dazzling smiles. "There," Lincoln said, "are you guys happy? You both won and got to share the prize."

They each grabbed one of his butt cheeks and squeezed. "That's not the only thing we're going to share," Luan said. She and Lynn leered at him like a couple of hungry dogs and he swallowed around a lump in his throat.

At home, they dragged him up the stairs, Luan holding one hand and Lynn the other. Lana, sitting on the couch, turned around and kneeled to see over the back. "What are you guys doing?" she asked.

"We're gonna play a game with Lincoln," Luan said.

"It's called hide the sausage, Lynn added.

In Lynn's bedroom, Lynn shoved Lincoln to the bed and mounted him, pinning his hands above his head. He stared up at her with a doe like expression that told her to stop; the thick bulge in his pants, however, told her to keep going. She trailed quick, rough kisses from the corner of his mouth to the side of his neck, the salty tang of his skin making her damp. She nipped his earlobe and his back bent off the bed, sending his boner mashing against her crotch. Lynn kissed his neck and his ear, her breathing heavy and her heart slamming. She brushed her lips across his and jammed her tongue into his mouth. He put up a half-hearted resistance but quickly gave in and kissed her back.

Luan knelt by his head, dressed in her skirt and blouse, the latter unbuttoned to reveal one small, tender breast. She pulled one of Lincoln's hands from Lynn's grasp and guided it under her skirt. When his warmth cupped her fevered middle, she threw her head back and thrust out her chest.

Pushing his shirt up, Lynn peppered his chest and stomach with wet, hungry kisses. Luan rubbed herself back and forth on Lincoln's hand and Lynn fumbled with the front of his jeans. She yanked them down and peeled his underwear over his package. It sprang out in a puff of musky air, and Lynn bit her bottom lip. Propping herself on either side of him with her hands splayed on the bed, she pressed her lips to the tip and jerked down, taking him all the way to the back of her throat. Luan knelt over Lincoln's face cowgirl style and lightly sat on him, her back bowing and her hands pressing to his chest. His nose dug between her ass cheeks and his tongue shot out to taste her honey straight from the source.

Lynn bobbed her head up and down, Lincoln's precum coating the inside of her mouth and sliding down the back of her throat. She pulled back and started tounging his balls. Lincoln wiggled his tongue in Luan's opening and she rubbed herself all over his lips and chin, her juices openly flowing now. Lynn raised up, yanked her shorts down, and popped her shirt off. Entirely nude but for her socks, she straddled Lincoln and sank herself slowly onto his dick. It spread her lips and filled her passage, pushing her walls apart in the most beautifully agonizing way possible. Lynn clamped down on her lower lip and rolled her eyes at the sensation of being full, then gasped when his tip touched her limit. Luan raised up and down on Lincoln's face as Luan began to bounce. It hurt like hell at first; fat veins stood out on the side of Lynn's neck and her teeth bared from her lips. Gradually, her body got used to it and it started to feel amazing. Luan cupped Lynn's cheeks in her hands and they gazed into each other's eyes, both keeping the same up and down rhythm. They leaned into each other and kissed. Their hands explored each other's chests and their tongues grappled for dominance. Lynn reached between Luan's legs, found her clit in seconds, and began to furiously rub it.

Lincoln gripped Lynn's hips and began to thrust up into her. Every time his tip slammed against the opening of her womb, a breathless gasp knocked from Lynn's working throat. She was hot from head to toe, her skin a deep shade of red, and her breathing was out of control. Lincoln felt so good inside of her, and Luan's hands felt so good tweaking and plucking her nipples, that she was going to blow. She bit her bottom lip and went faster, rocking and working Lincoln's dick, and then it hit her like a 300 pound linebacker. She seized up, let loose a wordless scream, and twitched like her name was Michael J. Fox.

When she was finished, Luan pushed her out of the way, bent, and started going down on Lincoln. Lincoln gripped her ass cheeks and licked her leaking pussy and puckered butt hole. Luan kneaded his balls with her hands and lashed his shaft with her tongue. She formed her lips tight around his sensitive head and went up, then down again. She wrapped her hand around the base of his dick and pressed her thumb into the strong, pulsing knot. That along with her expert oral skills did it: Lincoln bucked and hot, salty fluid filled her mouth. The way he gasped and shuddered sent her over the edge, and she came too, her girl juice smearing Lincoln's face.

Done, she rolled off of Lincoln and laid next to him. Lynn crawled up on his other side and they lay there, three panting, sweaty kids naked and covered with each other's sticky excitement. "You both really are winners," Lincoln said breathlessly.

Lynn licked his nipple and Luan rubbed a circle in his stomach. "We make a pretty good team, don't we?" Luan asked.

"We sure do," Lynn said and kissed the side of Lincoln's neck. She was starting to get turned on again and she really wanted to taste Luan's juices on Lincoln's dick.

"There's just one thing missing," Luan said and ran her fingertip up Lincoln's semi-erect penis.'

"What?" Lincoln asked.

Luan grinned. "Maggie."

Lynn hummed.

She shared Lincoln with Luan and it all worked out great, so she wasn't against the idea of sharing with Maggie too.

Plus, she did kind of want to lezz out with a goff.

"Maybe some other time," Lynn said. She mounted Lincoln, shoved her ass into his face, and licked his dick. "Right now, I wanna 69."

With a mouthful of cock and a pussy full of tongue, Lynn realized something.

Team work really is the best work.

She couldn't wait to add Maggie to the mix.
