Lincoln came out of the bathroom in a black dress suit, his coat unbuttoned to reveal the white shirt underneath. He loosened his tie and heaved a heavy breath. "Always a line," he said, and jerked when he noticed the readers. "Oh, hey, guys, what's up? It's Sunday in the Loud house, and you know what that means: Church." He started walking down the hall; Lisa rushed past with a beaker in her hand. Lucy followed, her nose buried in a book. "You know, I feel like a hypocrite sitting up in a pew and praising Jesus after finger fucking my own sister, but a happy hypocrite. Man, that was fun. You saw, right? What you didn't see was me licking and sniffing my fingers for the rest of the day. I know, I know, I'm a pervert. Sue me."

He reached his door and laid his hand on the knob. "I can't wait for what's next. Something tells me I'm going to be, uh, spending time with Luan soon. To be honest, that girl's given me more boners than anyone – even Ronnie Anne. I really like how she wears that skirt with her socks pulled up and..." he shook his head and made a long, hungry hmmmmummmmhum. He opened the door and stepped in...

Then froze.

Luan was on her knees next to his bed, her hands resting on the tops of her thighs. She was dressed in her skirt and white blouse, her eyes dancing with mischief and the corners of her mouth turned up in a sharp, sultry smile. Lincoln's heart skipped a beat. "Hey, Linc," she said, her voice low and alluring. She batted her eyelashes.

Lincoln looked at the fourth wall, his eyes wide. "I knew it."

Luan bit her lower lip as he shut and locked the door behind him. "How's it going?" he asked.

"Good," she said, "how about you?"

He shrugged one shoulder. "Alright."

His dick was getting hard, and Luan's eyes flashed with lust when she saw it twitching against his pants. She looked up at him and tilted her head playfully, her ponytail swishing across her shoulder. "Are you getting a boner, Linc?"

"Yes," Lincoln said.

"Hmmm...why?"

"Because there's a sexy girl on her knees in my bedroom."

"But she's your sister, Linc," Luan said.

"I know. That makes it even hotter."

She blushed and licked her lips; in the light of the sun falling through the window they glistened. "You're a pervert."

He shrugged. Why deny it?

She leaned slightly forward and smiled. "But that's okay. So am I."

"Yeah?" he asked.

She nodded slowly and beckoned with her finger. Lincoln went to her, his throbbing member leading the way. He stopped in front of her, and she sat up straight, her hands going to his stomach and softly caressing him. She looked up into his eyes as he reached down and stroked her cheek, then ran his fingers through her hair. She ran her hands over his bulge and squeezed him through his pants. A groan escaped his lips.

She unzipped his pants and he undid his belt; they pooled around his ankles. One thin layer separated him from her soft, wet lips. "Having a hard day, huh, Linc?" She asked. Looking into his eyes, she tilted her head forward and kissed his tip through his underwear. Her warmth seeped through and made him twitch.

"Very hard," he sighed.

"Let me...help you." She wrapped her lips around his head and curled her tongue against him. Lincoln's eyes rolled and his knees shook. The fabric of his underwear was wet with his precum and her saliva as she hooked her fingers into his waistband and pulled them down. He sprang out, and her grin widened. "Hmmm...hi, Lincoln." She pressed her lips to his head and touched his leaking slit with the tip of her tongue. A shudder went through Lincoln's body and he grazed his fingernails gently across her scalp. She giggled and leaned forward, an inch pushing past her pillowy lips.

Lincoln threw his head back and moaned. He ran his hands through her hair and pulled her closer, his shaft penetrating her further. The sensation of her saliva burning hot against him made his hips spasm, and he jerked forward; his entire length filled her, his tip hitting the back of her throat. She uttered a muffled sound of delight, then pulled slowly back, her tongue softly stroking his underside. She spit him out and looked up at him, her eyes big and burning with passion and her lips sparkling with a thick mixture of her spit and his precum. "Fuck my mouth," she said.

Lincoln cocked his brow.

She wrapped her lips around his head and didn't move.

Catching her drift, Lincoln laid his hands on either side of her head and thrusted into her mouth, then pulled back and thrusted again. Luan put her hands in her lap and looked up at her brother with big eyes as he fucked her, his balls slapping against her chin and his thick precum coating the inside of her mouth.

When Lincoln felt himself beginning to cum, he gave one last thrust, and spurted against the back of her throat with a cry, his head flopping back and his body tensing as he pumped his creamy seed into her stomach.

She pulled away and smiled, a long ribbon of cum coursing down her chin. "Thanks, Linc. You know, if you want..."

"Get on the bed."

Smirking, she got up and laid back on the bed, her hips flush with the edge and the tips of her toes pressed into the carpet. Lincoln knelt between her legs, reached under her skirt, and pulled down her panties. They were white with yellow smiley faces; they were soft and warm, like her. He drew them over her ankles and threw them away. Next, he pushed her skirt up, and grinned when his eyes fell upon her pink, glistening girlhood. He looked at the fourth wall. "I'm a nice guy. She went down on me...now I'm going down on her." With that, he buried his face between her hips, and she gasped as his tongue found her moist opening.

He laid his hands on her quivering stomach and tasted her slowly, her hot juices smearing his face and filling his mouth. She reached down and took his hands in hers as she began to pant. Her face was a lovely shade of pink and her eyelids fluttered. "L-Like that."

Instead, he went faster, moving up her slit and flicking her hooded clit. She arched her back, which drove his face deeper. "Yes!"

She rocked her hips against him as he swirled his tongue around her arousal. When he slipped a finger into her, she gasped and started to shake. "I-I'm c-cumming, Linc!"

Lincoln grazed her with his teeth, and she went off like a rocket, her body convulsing and a high-pitched cry trembling from her lips. She ran her fingers through his arm and closed her thighs against his head even as the rocking of her hips slowed.

"Wow," she moaned shakily.

Lincoln pulled back and wiped her orgasm from his mouth, "Yeah, wow."

"Best Christmas present ever."

"You're a pretty good gift giver yourself."

She propped herself up on her elbows and swung her legs onto his shoulders with a sly grin. "Expect another gift real soon."
