Lynn Loud clutched Lucy's tiny body close as her orgasm rocketed through her, her gyrating hips slowly coming to a stop. They were lying in Lynn's bed, Lynn's shorts around her ankles and Lucy's leggings on the floor and her dress hiked up around her hips. Lucy's butt was warm and slick against Lynn's throbbing girlhood. They had been taking turns doing this for almost two hours. It was nice, but it wasn't what Lynn craved. Like that old lady in the Wendy's commercial, she wanted the beef. Linco the pinko was sleeping, though, and he looked so peaceful that even in her lustful haze she couldn't bring herself to wake him.

Lynn's heart pounded against Lucy's back, and the smell of her sister's hair filled her nose. Under her hands, Lucy's stomach quivered. She was probably horny again. Well...Lynn couldn't have that. Her little sister was kind enough to peel off her leggings and hike her dress up when Lynn needed her...she deserved payback. Lynn kissed the nape of Lucy's neck and slipped her hand between her legs. Lucy sighed as Lynn rubbed her middle finger between her slit, where she was warm and moist and soft. Kissing her neck again, Lynn found her clit and rubbed it in quick circles. Lucy's gasps rose until she clamped her teeth down on the pillow and squeezed her legs together. She cried out and shook when she came.

"I don't know if I can cum anymore," she said.

Lynn sighed. "Yeah, I really need Lincoln's dick."

"Well, go on. He's probably awake."

"What time is it, anyway?"

"Almost midnight."

"Midnight?"

"Yes."

Oh. Well, scratch that. They had been taking turns rubbing against each other's butts for nearly four hours. Time flies when you're having fun, sure, but wow.

Lucy slipped out of bed and stood on quaking legs, putting her arms out for balance. Lynn got up and slipped her arm around her sister's waist. "Whoa, there, spooky, let me help you."

"Thanks."

Lynn helped her sister over to her bed, pausing to draw back the covers and then lifting them over her body. "Thanks," Lucy said again, this time with a little smile.

"No prob," Lynn said, bending over and kissing Lucy on the forehead. "Sweet dreams, sis."

"Have fun with Lincoln."

"Oh, I will."

The hall was dark and quiet. At one end, a light shone under Lincoln's door. She was halfway to it when she realized she forgot to put her shorts back on: She was wearing a pair of socks and a jersey that barely covered her. Oh well. She wouldn't need shorts for what she had in mind.

At Lincoln's door she knocked lightly.

"Yeah?"

Lynn turned the knob and poked her head in. He was stretched out on his bed, a book held up to his face. He was dressed in only his underwear, his taunt skin and budding muscles bared for Lynn to see. Her core tingled and she licked her lips.

He looked over the top of his book, and smiled. "I know why you're here," he said.

"Yeah?" she asked, challenging. "Why am I here?"

He threw the book aside and, keeping his eyes locked on hers, pulled down his underwear. His penis flopped out and twitched as it began to inflate. Lynn's jaw dropped and her eyes danced across its length. The tingle in her core became an inferno in her stomach.

He kicked out of his underwear and put his arms behind his head. His grin was so cocky, so self-assured, that Lynn found herself wanting to knock it off of his face...after she fucked him.

"What makes you think I'm here for that little thing?" She grinned against her will. It was anything but little.

He shrugged. "Eh. I could be wrong. I'll just take care of this myself..." He grabbed himself and started stroking.

"Oh, no you don't," Lynn said. She shut the door behind her and went to him with a grin. She knelt on the bed and leaned back on her knees, letting her eyes drift over his perfectly formed body, the fire spreading from her center and enveloping her whole body.

"You're cute when you blush," he said.

"Shut up," she said and bowed her head. He moved, and his penis swayed slightly back and forth. Oh, yeah. That was hot. She glanced at him, her ponytail swishing, then back to his dick. Her hand ached to touch it. She didn't want to give him the satisfaction of her going after it like a bitch in heat, though.

Ummmm, but she totally was.

Screw it. She reached out and wrapped her fingers around it. It was warm and full against her palm, the skin surprisingly soft and smooth. She looked at Lincoln's arrogant face and giggled...actually giggled, like a little girl. "It's nice," she said.

He reached up and brushed the back of his hand against her cheek. She blushed furiously and sucked her bottom lip in. "You're still blushing," he said.

She shook her head, the tip of her ponytail hitting either side of her face.

"Yes you are," he grinned.

He put his hand on the back of her neck and guided her lips to his: She was powerless to stop him...not that she wanted to. Their noses brushed and they kissed, their tongues meeting and slowly moving against one another. She shifted and hooked one leg over him, then shifted again. She was on top of him, his legs caged her between her thighs. Her sultry warmth showered his flesh. Jeez, all of his sisters were ovens.

She pulled back and positioned her hole at the tip of his dick. "So much for foreplay," Lincoln said.

She cocked her head and squinted her eyes. "Fuck you."

"You are."

She sank onto him, his penis shooting into her and pushing her virgin walls apart. She inhaled over clenched teeth. It hurt...but it felt good too. Just like Lucy said. Lincoln watched her with dark eyes and a tiny smile. She laid her hands on his chiseled chest and rocked her hips back and forth. He slipped his hands up her shirt and along her hips. Her skin was hot.

He scraped against her canal. She could feel every contour, every ridge. Her heart pounded and her mouth was dry: She tried to work up salvia but couldn't. She could however taste her brother's mouth still.

Licking his lips, Lincoln moved his hands up from her hips and to her breasts; his thumbs brushed across her nipples and she purred. Like a lioness mating with her king.

She rocked her hips faster and faster. The bed was shaking, the headboard slapping the wall. She didn't care about being quiet, though. The only way to enjoy the company of your sexy little brother is loudly. She went faster still. Lincoln tweaked her nipples and a mixture of pleasure and pain scattered into her brain. She could already feel herself beginning to tip over the edge. No, no, no! Don't cum, Lynn! Make it laaaaaaaast!

But nature won out. Lincoln squeezed her breasts and heat exploded through her. She hung her head forward and arched her back as she came. Lincoln touched her face and looked up at her with a grin. "Switch me spots," he said.

Wide eyed from her first orgasm with a boy (and Lincoln at that, yum!), she simply nodded and slipped off of him, stretching out beside him on the bed. He mounted her, and she parted her legs for him. He pushed his girl-cum coated tool against her, then jerked, surging into her with a gasp. Lynn cried out.

He hooked an arm under her leg and lifted it as he rhythmically thrusted into her. She closed her eyes and turned herself over to sensation. He lifted her other leg. Her ankles were resting on his shoulders, and something about that position made her feel so helpless, so vulnerable, so completely dominated that she moaned in pleasure. He could do anything he wanted to her, and she would have no choice but to let him, to lay back and watch it happen...

Another orgasm ripped through her body. Lincoln grabbed her ankles and thrusted so deep it hurt. She yelped.

"Take it, bitch," he panted.

"I'm your bitch," she gasped.

"I'm in charge."

"You own me."

"You do whatever I say."

She could feel another orgasm forming. "I-I-I'm your slave."

He thrusted smoothly, gliding on a mixture of their juices. She tossed her head back and forth. Jesus, she couldn't take it anymore. He suddenly went stiff. Why are you stopping? Then he swelled and bucked against her: When his hot cum pumped into her, she came hard, biting her lip so hard it bled, her hands flying to her head and tugging at her hair. She thrusted her hip as molten lava spilled deep into her stomach and formed a burning pool.

"Whoa," she breathed. "You're pretty good."

"At this point, I've had a lot of practice."

"You know what they say, Loud; practice makes perfect."

He grinned. "Was it perfect?"

She nodded. "Better than Lucy." She giggled.

He rolled off of her and laid his arm across her chest. Within minutes, he was asleep, his back rising and falling and gentle snores rising from his nose. Lynn leaned over and kissed the top of his head. "I love you, Lincoln."

She got up, and he started spilling out of her. She looked around, saw his shirt on the floor, grabbed it, and pressed it to her crotch. "Sorry, Linc."

With that, she waddled away, turning off the light and closing the door behind her.

In her room, Lisa watched. She glanced at another window. Luna and Luan were doing it yet again, Luan's head between Luna's legs and Luna's hand threading through Luan's hair.

She felt nothing.

The antidote worked. Thank God. Now, to convert it into a mist that could be distributed via the air vents. She would have done it earlier, but due to her parents and older siblings...condition...it had fallen to her to care for Lilly. Feeding, diapers, and bathing. By the time she was done with the latter her sweater was soaked and soap suds coursed down her face. She couldn't lie, though; she rather enjoyed herself.

She got up and went over to Lilly's crib, using a step stool to peer over the railing: The youngest Loud was lying on her back, one hand curled into a tiny fist. Lisa smiled then went back to her computer. Lincoln was lying on his stomach asleep, his bare butt whiter than his arms and legs. One day, she thought, she would develop a sex drive and figuratively become a woman. For now, however, she was content to focus on her studies. If her libido was anything like her sisters', once she did develop a sex drive, she would have time for little else.

Sighing, she went off to ready the antidote.

Luan flopped back against her sister's bed and lifted her skirt. Between her legs, Luna watched her with half-lidded eyes. "It's strange."

"What's strange?" Luan asked.

"I expected you to taste funny. Get it?"

With that, Luna dipped her head, and Luan took a deep breath as that warm, wet, talented tongue attacked her genitals. Didn't she want to have sex with Lincoln? Oh, yeah, she did...but that was before she discovered how good Luna was.

Luan ran her hands through Luna's hair and lifted her hips. Nothing...oh...could top...uhhhh...a sister's...ahhhhhh...kiss.
