Leni Loud was the first one awake the next morning. She had no reason to be, since it was Saturday and she hadn't set her alarm, but here she was at 6am, sitting up in bed and absently scrolling through her phone, the harsh blue light stinging her eyes even though the screen brightness was set to 35 percent. In the next bed over, Lori was a shapeless form, silent save for the occasional snort. Leni almost envied her older sister; Lori's mind was free and clear, populated only by Bobby and, like, getting her nails done or something. Meanwhile Leni's was haunted by the specter of her younger sister.

And the way she was acting.

Leni could forgive the dirty joke Luan told Lincoln yesterday morning, but all that afternoon, she saw signs that something wasn't right. Luan staring at Lincy like he was a piece of meat and she was a hungry dog, Luan...well, that was the only thing Leni had actually seen, but she saw it multiple times. Then, before bed, Lucy mentioned something about another dirty joke Luan told Lincoln, this one even worse than the first.

Was Luan...like...interested in Lincoln? Like...in that way? Leni had been interested in several boys over the years, and while she couldn't honestly saw how she looked at them (she didn't exactly whip out a mirror and study her expression...she wasn't Lola), she was pretty sure she'd given at least one or two the kind of eyes Luan had been giving Lincoln yesterday. She wound up sleeping with one of them. Well, not fully, but they did things in his room while his mother wasn't home, things that are fine when you do them with someone who isn't your brother.

Maybe she was overreacting. Maybe it was completely innocent and she was twisting it in her head. She had always been protective of Lincy. He was like a cute little puppy dog, and bad things sometimes happen to cute little puppy dogs, because they're so loyal and trusting. Just look at those sad commercials with the poor dogs that got beat up and abused. No one was going to beat up and abuse her Lincy. No one.

But Luan didn't want to beat up and abuse Lincy, right? Luan was his sister and she loved him the same as Leni. Leni was just edgy, that was all. Lincoln was growing up and would be dating soon. She'd realized that for a while now, and it kind of scared her, because some girls are total bitches, and being the cute little puppy dog that he is, Lincoln could very well fall victim to them. Seeing Luan looking at him in what had to be familial love sort of...triggered her. That was all. It had to be.

Even so, she had a heavy feeling in the pit of her stomach. She looked up from her phone, gazed into the early morning gloom, and tried to identify just what that feeling was. Dread? No, not quite. Uncertainty? Maybe. Whatever it was, it told her to watch Luan, because even though Luan was her sister and Leni loved her, she might be one of those bitches who would beat up and abuse Lincy, even if she didn't necessarily mean to.

Leni sighed. That was the thing about abuse. The person doing it sometimes didn't even know they were doing it.

Luan couldn't be like that, could she? No. She was a good sister. Well...maybe. You never really knew. The way she was looking at Lincoln, leering...

Could have been nothing.

Leni sighed. She was so conflicted and confused that she thought about waking up Lori and telling her about it, but didn't.

Lincoln Loud dragged himself out of bed at half past seven that morning and trudged to the bathroom, his eyelids glued together and his head still full of sleep. He assumed there was a line for the bathroom, but didn't know until he bumped into someone.

"Sorry," he muttered.

"No problem, Linc," Luan said, and Lincoln's heart dropped. Aw, shit.

Great way to start your day, Lincoln; literally bumping into the one person in the world you're trying to avoid. Why don't you trip over your own stupid feet and grab her tits on the way down while you're at it?

Speaking of tits, the thin fabric of her nightgown clung lightly to her budding chest. Lincoln could just make out her nipples, and his body went flush. He glanced away and subtly covered the crotch of his briefs. Why didn't he think to get dressed before coming out? He was a strategist, goddamn it! He should have planned this out.

Only...maybe he did plan it out.

Spinning on his heels, Lincoln went back to his room, closed the door, and sat heavily on the edge of the bed. This is bullshit. Why couldn't she just leave him alone? Why did she have to tease him this way? If this kept up, he might do something he'd regret, and she probably would too. If she was anything like him, she came to her senses after a good release. Once that release came, she'd realize what she'd done (and he would too), and they wouldn't be able to look each other in the eyes ever again. Hell, they probably wouldn't be able to stand being in the same room ever again. That's not the kind of relationship he wanted with one of his sisters.

But damn, those legs...those chestpieces!

Shut up, you fucking idiot! Just shut up! Shut up! Shut up!

He got up, went to the door, and peered out. There she was, facing the bathroom, her hands behind her back and her shoulders dipping back and forth. This wasn't a field trip, this was a war, and if she wanted to play dirty, he'd play dirty back.

When his eyes started creeping down her back toward her butt, he closed the door, hurriedly dressed, and then went into the hall. Alright, he thought with a deep breath, let's go to war, you bitch.

He got in line behind her. She turned. "Hi, Lincoln," she said with a little grin.

He nodded. "Hey."

"How did you sleep?"

He shrugged one shoulder.

"That's not an answer, silly."

"You mind if I cut in front of you?" he asked, ignoring her comment. "I gotta piss."

Before she could answer, he ducked around her.

He could sense that she wasn't entirely happy, but she didn't say anything. See how bad you want an asshole, he thought with a wicked little grin.

Forceful, Luan thought with her own smile. I like that.

"Got any plans for the day, Linc?"

"Yup."

"Oooh, what?"

An idea hit him. "Ronnie Anne's. We're getting pretty serious these days. Hand-holding. You know, the whole nine yards."

Good thing I'm not looking for a boyfriend, just a brother with benefits...

"That's nice. Have you kissed her yet?"

"Totally. You know, with tongue. And lips."

This time when Luan spoke, he could feel her hot breath on the back of his neck, and shuddered. "Did you like it?"

Lincoln shrugged. "I like kissing Clyde better."

He bit down on the insides of his lips to keep from laughing.

Unfortunately, Luan took it as a joke. "You're hilarious, Linc!" she said, swatting his arm. "You should do stand-up."

That hot breath on his neck again, the sensation that her pretty pink lips were mere inches from his skin. "Or lay down."

Just then, the door opened and Lynn came out in a puff of steam. Seizing the opportunity, Lincoln brushed past her, closed the door, and locked it. Damn it. This was going to be harder than he thought. Did he really have to be a giant bastard just to get her to cool it? He didn't want to be, it went against his nature, but let's face it: He was a disgusting piece of shit and the more she did this, the more he wanted her. If he didn't shake her, he'd wind up losing his mind and doing her.

After pissing, Lincoln went into the hall. Luan smiled. "Linc!"

"Move, bitch," he said, shoulder checking her as he passed.

Luan gawked, her jaw dropping to her chest. Why, that little...

She shook her head. She got moody too when she was randy, and Lincoln had to be randy for her, because she'd seen at least three erections in his pants since yesterday, the last one just now. It almost jabbed her as he passed. She wished it had.

Is...is he playing hard to get?

Luan had a revelation. No, he wasn't. He was in denial. He didn't want to admit he wanted to sink himself into her warm, wet, inviting body. An evil grin spread across her face. Alright, Lincoln Loud, I guess I'll just work ten times as hard.

Oh, yes she would.

Come hell or high water, they were sleeping together before Monday.

After breakfast, Lynn grabbed her bat and ball and headed off to Ronceverte Park, intending to find someone to play with. Lincoln, the only one who played sports with her, was busy being a dick, which didn't make sense. Lincoln was a nice guy. Today, though, he was being an obnoxious bastard. Oh well. Everyone wakes up on the wrong side of the bed now and then.

She reached the park fifteen minutes after leaving the house. Kids ran wild on a playground while their bored mothers looked on. A bunch of guys were playing Frisbee in a grassy field, and a black family was clustered around a group of picnic tables, barbecuing. She walked around, hoping to bump into someone she knew, but the only face that was even vaguely familiar belonged to some dork with red hair and glasses. Did they go to school together? That had to be it. Maybe...

"Hey, Lynn!" a familiar voice called out, and Lynn cringed. Son of a bitch.

Putting on a smile, Lynn turned. Amber Paulson was coming over, wearing tight jeans and a black shirt that stopped just above her naval. Lynn's eyes lingered for much longer than she meant them too. "How's it going?" she croaked when Amber walked up.

"Alright," Amber said, "I was just out taking a walk when I saw you and I was like 'oh, shit, it's Lynn Loud.'"

"Yup," Lynn said, "it's me."

"What are you up to?"

Lynn shrugged. "I was just looking for someone to play ball with." She held up her bat and ball.

"Let's go!"

Lynn blinked. "Huh?"

"I said let's go. I'm bored as shit."

Lynn swallowed hard. She was having the thoughts again, and she wanted to run from them, but looking into Amber's clear eyes, she also wanted to embrace them.

"Alright," she grinned. "You any good?"

"A little."

"You pitch," Lynn said. They were walking through a stand of trees to an expanse of field.

"Alright. Your funeral."

That shocked a chuckle out of Lynn. "You think?"

Amber shrugged. "Maybe. And maybe you're better at baseball than you are at football." She nudged Lynn's ribs to show she was kidding. Even that small contact made Lynn's heart flutter.

"Yeah? We'll see."

And see they did: Of five pitches, Lynn only hit two, the crack of the bat against the ball washing away her anxiety. She missed two in a row; the last time, she swung hard and spun, falling to the ground with a high-pitched "Whoa!"

Amber covered her mouth and laughed so hard she doubled over. Blushing, Lynn got to her feet and brushed herself off. "You're good at falling down," Amber said, "I'll give you that."

Blushing even harder, Lynn lifted the bat. "Throw another."

"Any more and you'll break your neck," Amber said. She came over, took the bat from Lynn, and shoved the ball into her chest. "Let's switch."

"Alright," Lynn said. "Your funeral."

"Ooooh. Big shit talker."

Lynn got into position and wound up. Amber took a swinger's stance, and Lynn's throat went dry at the sight of her fleshy hips. Her hands ached to touch them...

"Come on, Loud," Amber said, swinging the bat, "show me what you don't got."

Grinning, Lynn threw the ball: Amber swung, the bat cracked, and the ball flew high into the sky. Lynn, pressing her hand to her forehead, watched it disappear into a dense stand of trees.

Damn. She was cute and good.

"Nice job," Lynn teased, turning. "You hit my ball into the next state over."

"Oh, don't be a baby," Amber said, coming over. "Let's go get it."

"That thing's gone."

"You're a pessimist or something," Amber said, brushing past Lynn. The way her heart-shaped butt moved under those jeans...it was enough to drive a girl crazy.

"Where are you going?"

"To get your ball," Amber said, turning and walking backwards. "You gonna stay here and throw yourself a pity party or are you coming with me?"

Lynn sighed. "Wait up!"

They walked side-by-side into the forest, the treetops blocking out most of the sunlight. Inside, it was a good ten degrees cooler, and slimy moss covered everything. It looked like one of those dumb fantasy movies Lincoln liked so much. Only creepier.

"You know, don't worry about it," Lynn said, "I have a bunch more at home."

"Come on," Amber said. "I feel bad I lost your ball."

"No, really, it's fine. We'll never find it in here."

"You don't know if you don't try," Amber said over her shoulder.

Fine. Whatever.

A narrow path wound through the brush, bending around a giant boulder spray painted with names and dates. BILLY 88, BJ+AH 1995, a giant swastika...a penis.

"It kind of pisses me off that people do that," Amber said, stepping over a fallen branch that lay across the path.

"Yeah, it's bullshit," Lynn said absently, picking her way over the same branch.

"Like, why do you have to fuck up nature? Go write that stuff on a dumpster or something." Ahead, the path turned into three. The trees fell away until they were few and far between. Between them was tall, grass. The earth was wet and spongey. Frogs croaked. Bugs whined.

"You know, Loud," Amber said, putting her hands on her hips, "I think you were right. Fuck this."

She turned. "I still feel bad, though, so I tell you what: I'll give you one of my balls."

"You're fine," Lynn said. And yes she was. God, Lynn wanted to kiss her so bad. She didn't care if it was wrong or disgusting or anything else.

"No, I'm giving you one of my balls. I lost your ball, so I'm replacing it. I only live a couple blocks away. We'll be there in, like, ten minutes. Well, twenty, since we're in the middle of nowhere."

"Alright," Lynn said. Amber passed by, and Lynn fell in behind her, openly looking at her butt and the bare small of her back: The dimples at the base of her spine were so sexy Lynn had to take a deep breath. She felt herself start to dampen, and quickly readjusted herself so that her underwear wasn't sticking in the cleft of her crotch.

"What other sports do you play?" Amber asked as they emerged into the daylight.

"All of them," Lynn said.

"All the sports?"

"For the most part."

"Even the lame ones?"

"Pfft. What sport's lame?"

"I don't know," Amber said. "Croquet?"

Lynn stopped. "Yeah," she said, hurrying to catch up, "croquet's pretty sucktastic."

Amber snorted. "Sucktastic, I like that."

And I like you, Lynn thought.

"Hey, Linc, wanna watch a comedy video with me?"

"You wanna leave me alone?"

Lincoln was sitting on the couch. A boring movie was on TV. He was watching it but not paying attention. He checked his phone, but Clyde hadn't texted him back. If he didn't within the next ten minutes, Lincoln was going to jump on his bike and go out alone. To the park, the arcade, the hardware store...anywhere Luan was not.

Luan stepped in front of the TV and held her arms out like Jesus on the cross. Her eyes danced with malicious glee, and the corners of her mouth were turned up in a smug little grin. "You don't want to spend time with your sister?" she asked.

"Nope," Lincoln said, "I want my sister to move."

She leaned forward and rolled her hips. "Come make me."

Lincoln started to get up but stopped. Nope. That's what she wanted, him to put his hands on her. That's what he wanted too.

"Whatever," he said, picking up his phone and logging into Facebook. He scrolled down his newsfeed but it was stuffed with the same shit it always was. Cat videos, political arguments, vaguely racist relatives. Ugh. Why are people so annoying? He got the urge to chuck the phone across the room (or at Luan's head), but resisted it. If his phone broke he was fucked.

"Come on, Linc," Luan said, coming over and dropping onto the couch next to him. "What's the matter?"

He fought to keep from looking at her. Keep your head down, Lincy. Don't give the evil bitch the satisfaction. His neck quivered, his face twitched. He broke down and looked. Her blouse was slightly unbuttoned, the fabric pulled away from her chest, and...sweet mother of Jesus, he could see her breast! His eyes widened and his jaw snapped open. Luan crossed her legs and grinned at him. "What's that look for?"

Nerves of steel, nerves of steel, nerves of steel.

"I-I just can't believe you're still bugging me. Take a hint."

She grabbed his hand and threaded her fingers through his. "But Lincoln, I want to spend time with my brother. Even if he is PMSing."

Her hand was soft and warm and smooth. His heart thudded, and he yanked away. "Well, I don't want to spend time with my sister."

Luan drew her legs up onto the couch and leaned forward, grabbing him by the front of his shirt. "Yes you do. You're just in denial."

Lincoln ripped away and jumped to his feet, his penis starting to waken. "Gotta go."

He raced upstairs, almost knocking Leni down as she descended. "What's wrong, Lincy?"

"Gotta poop!" Lincoln called back, darting into his room. Leni doubted he really had to poop. If he did, he wouldn't be going into his bedroom.

At the bottom of the stairs, she saw Luan sitting on the couch, and her brow furrowed. You have something to do with this.

Leni walked up to the back of the couch and bent over. Luan was placidly watching the screen. "What's up with Lincy? He's acting strange."

Luan shrugged. "I don't know. His time of the month, I guess."

"I think you know more than you're letting on."

Luan looked at her. "What's your problem, Leni? Ever since yesterday you've been acting like..."

"No problem," Leni said coldly, standing. "I just want to make sure my brother, whom I love, is okay."

Upstairs, Leni knocked on Lincoln's door, and it opened. "Hey," he said, coming out. "What's up?"

"Are you okay?"

Lincoln blinked. "Yeah, sure, fine, I was just going to ride my bike."

"Oh," Leni said, "okay. Is...?" She hesitated. Might as well get it out in the open. "Is Luan bothering you?"

Lincoln swallowed. "Yeah, you know, normal sister stuff. I gotta go."

He fled down the stairs, and Leni watched him. Maybe she was overreacting.

In the living room, Luan glanced over her shoulder as he passed. "Where you going?"

"Out," Lincoln said.

"Oh, I'll come with you."

"No you won't."

He practically ran through the kitchen and out the back door, then around the side of the house to where his bike was chained to a pipe. He unlocked it with trembling fingers, hopped on, and pedaled off, looking over his shoulder.

Luan was not there.

Whew.

Nice try, bitch, but I'm Lincoln Loud, and I have nerves of steel.

Luan watched from the front window as Lincoln sailed by on the sidewalk. Soon, Lincoln, we'll have sex. I want it, you want it, why fight it?

She did like the teasing, though.

It was making her wet.

Amber Paulson lived in a tiny house with blue siding and white trim on a side street four blocks north of the park. The front yard was boxed in by a chest-high chain-link fence and dotted with lawn ordainments. Garden gnomes, pink flamingos, a gazing ball on a faux marble pedestal.

"My grandma," Amber explained as she opened the front gate. "She likes all that stuff."

"You live with your grandma?" Lynn asked.

"Yeah, my mom's in jail and I don't know about my dad."

"I'm sorry," Lynn said.

Amber shrugged. "Whatever. Shit happens. Let's get you that ball."

They followed a flagstone walk to a covered porch laden with potted plants and wind chimes that tinkled in the breeze. Amber produced a key from the pocket of her (tight...so tight) jeans and opened the door. Inside, Lynn looked around a small, cozy living room. The furniture looked like it came from the seventies: The couch was a wild splatter of brown pixels with a crotched throw blanket over the back. An armchair faced a boxy television set. Framed photos hung on the walls. The smell of Ben-Gay was heavy in the air, a smell Lynn was familiar with. The house felt...empty. "Is your grandma here?" Lynn asked.

"Nah," Amber said, "she's at the church. Where she always is. If they had two more volunteers like her they could take over the world. My room's this way." She led Lynn down a short hall to an open door. Amber's room was much like Lynn's own: A neatly made bed, sports posters on the wall, a dresser crammed with trophies. A basketball sat in the middle of the floor. A football lie near the closet door.

"This is it," Amber said, "home."

"It's nice," Lynn said.

"Thanks." Amber said. She crossed to a dresser, opened a drawer, and took out a baseball. "Catch."

She tossed it, and Lynn caught it.

"You're not bad in close quarters," Amber said, dropping onto her bed. She stretched, and Lynn's eyes crawled over her supple body. She coughed and blotted her sweaty palms on her gym shorts.

"You wanna sit down?" Amber asked. "You're making me nervous standing there like that."

Lynn swallowed and sat stiffly on the edge of the bed, facing away.

"This town is boring," Amber said, yawning. "What do you do for fun?"

Lynn shrugged. "Not much. Play sports."

"That's all?"

Lynn thought. What else did she do? Nothing, really.

"Yeah, pretty much."

"Not bad." Amber sat up and ran her fingers through her hair. Her leg was touching Lynn's, and Lynn's heart beat a crazy tempo. "About all there is to do here, I guess."

"Yeah," Lynn said. She barely resisted the urge to put her arm around Amber's shoulders and kiss her luscious lips. "I gotta go."

She stood.

"What? Come on, you just got here!"

"I'm sorry," Lynn said, "I-I..." she couldn't think of a good excuse.

Amber sighed. "You're the only cool person in this town and you're going to flake."

"I'm sorry, I..."

"It's fine," Amber said. She got up and stood before Lynn, a vision of perfection. She was slightly taller but their lips almost totally aligned. "You can go if you want." She leaned in, and her lips brushed Lynn's. Lynn's heart sputtered to a stop and Amber's tongue darted into Lynn's open mouth.

Recovering, Lynn kissed her back, finally grabbing those beautiful, fleshy hips and pulling the other girl closer. Amber's hands ran through Lynn's hair and along her cheeks. Lynn's center turned to jelly, and she felt herself starting to leak.

Amber rested an arm on each of Lynn's shoulders and broke the kiss, leaning back with a smile on her face, her cheeks looking as red as Lynn's felt.

"You still want to go?"

Sucking in her lips to keep from smiling like an idiot, Lynn shook her head.

"Good," Amber said, "because I don't want you to."

Clyde wasn't home, so Lincoln biked to the park, shifting in his seat to accommodate the erection he'd developed as his traitor mind called up images of Luan's breast. He imagined how it would feel under his hand, and his penis slammed against the crotch of his pants, trying to get out. It would be warm and fleshy, the skin smooth. How would the areola feel? The nipple?

Don't fucking worry about it.

By the time he got to the park, he was so hard it hurt, and he was sure that if he got off his bike and tried to stand, he'd poke someone's eye out, so he followed one of the bike paths through the forest and along the river. At one point he saw a man in overalls sitting against a tree and smoking a cigarette, a fishing pole in his hands. Fishing. That sounded like fun. Cast your hook into the water and sit there while you wait for something to nibble and smoke cigarettes and don't think about your sister's body. Fun. Loads of fun. The air was warm. He wondered what the water felt like. He could use a swim. Just strip down to his underwear and breaststroke along and not wonder what Luan's tongue tasted like. He was starting to get tired. He should stop for a chest – er, rest.

When he reached the end of the trail, he followed a narrow paved road back to Park Street, and headed west. His groin ached, his head spun. He could think only of Luan's breast and her legs and her butt. Ahhhh. He was losing the battle! Just like he knew he would...just like he secretly hoped he would.

He needed to get home and jack off. If he didn't relieve the pressure, he would explode...all over his sister.

He pedaled as fast as he could, the wind rushing past his head. Hurry, hurry, hurry, gotta blast!

When he reached his house twenty minutes later, he dumped his bike along the side of the house and hurried into the backyard, where he froze. In his absence, someone had set up a pink inflatable pool. Luna was sitting in it, her arms resting on the side. Lori laid on a towel nearby. Lana and Lola splashed around, Lola admonishing Lana for getting her hair wet. Leni was asleep in a lawn chair, her mouth slightly open and a ribbon of drool hanging from her bottom lip. He realized his erection was clearly visible, so he bent and covered his crotch with his hands.

"Hey, Linc!" Luan said from behind him, and he spun so quickly that he nearly fell over. She was wearing a pink two-piece bikini that was a size too small. Her stomach was flat, her flesh smooth and milky. Her breasts strained against her top, and as she passed, he noticed that her bottoms had given her a wedgie...on both ends. "You up for a swim?" she asked in a seductive tone. In her eyes, Lincoln saw one word: Checkmate.

"N-No. I-I-I gotta go. Pee. I gotta go pee."

He fled into the kitchen and through the living room, fighting the urge to look back. Upstairs, he slammed his door and sat. He was this close to splitting his pants. Damn it. Damn it. Damn it. If this is what she wanted, fine. He'd go down there, bend her over the picnic table, and fuck her in front of everyone. Right up her ass. Fitting. For an asshole.

Stupid Luan.

Shaking with rage and excitement, he slammed his fist against his leg. Calm down. Whack off and you'll be able to think more clearly.

Standing, Lincoln whipped off his pants and laid down, wearing only his socks, underwear, and shirt. In position, he started to pull down his underwear when the door opened and Luan came in, a giant smile on her face. Lincoln jumped. "Luan! What are you doing?"

Leaning against the door, she grinned. "I was just coming to see if you wanted to come down for a swim, but I see you're...busy." She bit the bottom of her lip, her eyes flooding with lust. Lincoln's erection throbbed against his covering hands.

She started coming forward, and Lincoln twitched. "Luan, look..."

Ignoring him, she climbed onto the bed and crawled toward him, her eyes burning. He didn't move as she mounted him, her barely clad thing rubbing against his barely clad thing, sending pinpricks of sensations into his nerve endings. Her face hovered inches from his own.

"Luan," Lincoln moaned miserably, "please..."

She pressed her finger to his lips. "Shhh."

"But you're my..."

"Linc," she said, pressing the tip of her nose against his; the movement caused her to rub against his boner again, and he trembled, "don't worry about that. Just...listen to your body."

Taking his face in her hands, she tilted her head and kissed him, her tongue boldly entering his mouth. He was lightheaded, his dick throbbing against her. He ran his own tongue against the bottom of hers, and she shivered. She slid herself against him, and he moaned. There was not much separating them: He could feel his head slipping along her sweet divide, and hot passion burst across his brain. He grabbed her by her hips and pulled her closer. The kiss broke; she wrapped her arms around his neck and buried her face in the crook of her neck. She was making noises in the back of her throat: Purrs, sighs, grunts.

Lincoln laced his hands across the small of her back and held her as she rubbed herself against him faster. His heart was slamming and he could feel his orgasm gathering deep in the pit of his stomach. He kissed the soft skin of her neck. The salty taste of sweat filled his mouth, and he quivered. She was going faster still, grunting and uttering wordless sounds of pleasure. His underwear was damp with his precum and her fluid. He could more easily feel her now, feel the head of his dick rubbing between the parted folds of her sex. The friction was driving him crazy. He was approaching the edge and trying to hold back because it felt so good.

Luan cried out through clenched teeth, and he could feel her beginning to tremble with climax. That pushed him over the edge. Gritting his teeth, his eyes narrowing to slits, he felt his penis swell...then burst, pumping sticky warmth into his briefs. Luan jumped, having felt it, and bit his shoulder to keep from screaming. For a brief moment, she was a quivering, quaking mass of orgasm, her toes curling and her eyes rolling into the back of her head. Then she rolled off and laid next to Lincoln, her heart pounding, her temples pounding, and her lung aching.

"That didn't take long," she said with a giggle. She glanced over at her brother. He was sitting there, his head tiled back, breathing heavily through his nose. His face was the cutest shade of red she had ever seen. It was almost like a fire truck.

And speaking of fire truck, his hose still tented the crotch of his soaked undies. Luan smiled at it and reached out, touching it, the warm, wet feeling of their mingled passion making her stomach flutter.

"We're going to regret this," Lincoln said.

"Why?" Luan asked.

"Because...we're brother and sister."

Luan shrugged. "So?"

"This kind of thing might ruin our relationship."

She laughed. "It's just sex, Linc. It's not like we're getting married. Lighten up."
