Icy claws of terror dug into Lincoln's heart. Lynn snapped her head around and fixed Luna with wide-eyed shock. "What?"

Luna nodded smugly. "You made him touch Luan's boob, so I'm making you touch his dick."

Scarlet rushed across Lynn's freckled cheeks. "No! I'm not touching him there!" She threw him a glance, and he looked away, his hands reflexively dropping into his lap and covering the erection that still throbbed between his legs.

"What's wrong?" Luna teased, "afraid you're gonna like it?"

"No!"

"She's totes gonna like it," Leni said.

"I'm not gonna do it," Lynn said definitely and crossed her arms in punctuation.

"Then you can't play anymore," Luna said. "Go hang out with Lori."

Lynn glanced nervously at Lincoln, then to Luna. She was afraid she would like it...the way she liked seeing Lincoln and Luan kiss. She really liked that...she wouldn't be moist if she didn't. She took a deep breath as she remembered all the times in the past Lincoln came into the hall in the morning with an erection pushing out the front of his briefs...all the times she caught herself staring down at it and wondering what it looked like...what it felt like. Warm, she imagined, very, very warm.

No. Come to think of it, she wasn't afraid she would like it. She knew she would like it.

"Get lost," Luna said, smacking her arm. "You and Lori can compare Bobby and Billy-boo-boo-bear."

"Shut up," Lynn said. "I'm gonna do it."

Lincoln's stomach twisted. Kissing Luan was one thing...but letting Lynn touch his thing?

Before he could protest, Lynn ducked under the coffee table and popped up next to him. She looked as nervous as he felt. "Uh...I know it's awkward, but it's the rules," she said and scratched the back of her neck.

He opened his mouth to speak, but his mouth snapped closed when her hand dipped between his legs and cupped his package; her finger accidentally brushed across his sensitive tip and he jumped, nearly falling back but throwing out his arms and planting them into the carpet behind him.

Lynn's cheeks were bright red and her breathing was ragged. She swallowed and traced his outline with her middle finger. His breath caught as pleasure radiated out from his center and crackled along every nerve ending in his body. Lynn trailed her finger down to his soft sack, then slowly back up along his twitching shaft. Her eyes were wide and her lips parted: She looked a lot like Luna's impression of Luan watching porn.

"That's right," Luna snickered, "take your brother to second base."

Lynn ignored her; all that existed was the rigid thing under her fingers...so hot that its heat seeped through the denim covering it and kissed her fingertips. Her core burned with primal need; every instinct in her body told her to free him, pull down her shorts, climb on top of him...and bring her hips down...slowly down...until his body parted hers and sank into her waiting womb...

She glanced at Lincoln. His face was red and his eyes were muddled, his lips slightly parted and his chest heaving. He looked at her, and their eyes locked. She saw in them the same thing she knew he saw in hers: Shame...hunger...confusion...and passion. She flatted her palm against him and moved slowly along his length. His eyelids fluttered, and his arms gave out; he fell back against the floor and took a deep breath. When she reached his tip again, she felt something and looked down: A tiny dark patch had formed where his head touched the inside of his jeans. He was wet just like she was. She clamped her bottom lip between her teeth and made a kneading sound in the back of her throat.

"Okay," Luna said, "you're good."

Lynn pressed her thumb to the tip of his penis, pressed firmly, and made a slow, lazy circle. Lincoln's back arched and he moaned. "L-Lynn...stop..."

On some primitive level her body could sense his rising arousal, and it ached to join him.

"Lynn..." Luna said, "I said stop touching his dick."

Lincoln dug his heels into the carpet and flopped his head back against the floor with a hollow clunk. Lynn's fingers reached his zipper and started to pull it down. She was holding her breath now.

A plastic cup struck her in the side of the head, bringing her back from the edge. She threw a glance at Luna, who was leaning over the table. "I told you to knock it off!"

"I knew she'd like it," Leni said with half-lidded eyes.

Lynn looked down at Lincoln, his body stretched before her and his erection pressing needily against his jeans. She didn't want to stop, she wanted to keep going. She reached out for him, but Luna threw another cup at her head. "Don't even think about it!"

Sighing, Lynn turned away from Lincoln and drew her knees up to her chest. Alright, okay, yeah, it's for the best, because she was this close to losing her virginity to her brother, and that's a bad thing, right? Only hillbillies screw their brothers. Her eyes were drawn magnetically to his bulge and her heartbeat stumbled. Was it really that wrong, though? They were related...so what? That only counted for making babies...

"What's the matter, Lynn?" Luna asked tauntingly, "don't wanna play anymore?"

Lynn looked at her. "I didn't say that," she said.

"Then give me a dare."

Lynn saw a twinkle in her sister's eye, and knew exactly what she wanted to do. Or roundabout. Lynn smirked. "Kiss Leni."

Luna's shoulders slumped. "What?"

Leni at up straighter, a shadow of doubt crossing her face.

"Kiss Leni. With your tongue."

That's not what Luna wanted to do...which is why Lynn dared her to do it. Lynn glanced at Lincoln. He was sitting up now, his hands folded in his lap and his head bowed. He looked like he was trying (and barely succeeding) to keep himself together. Oooooh, Lynn knew exactly how he felt: One stiff breeze and she'd fall to pieces.

Leni and Luna both looked at each other. "I totes don't want to do this," Leni said.

"Neither do I," Luna said.

"Then you guys can go hang with Lori," Lynn said. She glanced at Luan. She looked a lot like Lincoln. "Me, Linc, and Luan will keep playing." She turned a sinister grin to Luna. She hoped they left...because when they were gone...

Luna sighed. "Alright," she looked at Leni, whose teeth were bared in a nervous expression. "Let's do this."

Lincoln looked up just in time to see Luna tilt her head and press her lips against Leni's. Leni's big, uncertain eyes went wide...then fluttered closed, her hand lifting to Luna's head and her fingers raking through her short brown hair. Luna got her knees under her and took Leni's face in her hands.

They looked like they were enjoying it. "Alright," Lynn said, "that's enough."

Luna pulled away and but still held Leni's face. They both smiled at each other. "Not bad," Luna panted.

"You're a good kisser," Leni said.

Luna stroked Leni's hair. "Get a room," Lynn grumbled. She wracked her brain for something to have Leni do. She glanced at Lincoln. He was still trying to keep from falling apart. It was kind of cute.

It would be even cuter if he did fall apart.

"Hey, Leni," Lynn said.

"What?" Leni asked.

Lynn flashed a toothy grin. "Let Linc touch your pussy."

Lincoln's head shot up and Leni blushed. "Well..." she said, "I guess." She gave Lincoln a seductive look. "Do you wanna touch my kitty, Lincy?"

Why even lie anymore? Unable to look her in the face, he nodded.

Leni pushed up and came around the table with an exaggerated swish of her hips. She stood over him and looked down with a hazy smile. "Are you, like, gonna look at me?"

He forced himself to look up at her. Her big brown eyes were filled with love and tenderness. "You're like a shy little puppy dog," she said, "it's adorable." She reached under her dress, hooked her fingers into her panties, and pulled them down, wiggling her hips. Lincoln's eyes darted down as she slid them down her ample thighs, then followed them as they slid over her knees. She stepped out of them and kicked them aside. He looked at her crotch.

She was naked underneath.

Lincoln shivered delightedly.

"Go ahead," she said, "touch it."

Lincoln took a deep breath and reached out, his fingers grazing her fleshy inner thigh. It was warm and soft, like Luan's breast. She giggled. "Lincy, that tickles."

Swallowing, Lincoln rubbed his hand up, his fingers dancing along her skin. The higher he got, the hotter it got, his sister's natural heat caressing his flesh. He got onto his knees and Leni laid her hand on the top of his head.

His fingers brushed against her lips and his heart leapt. He turned his hand and pressed his palm against her, the very tip of his middle finger sinking slightly between her silky folds. The heat was incredible, and she seemed to get hotter by the moment. "Hmmmm," she said, twirling her finger through his cowlick. He moved his hand and dragged his finger along her slit. She was wet. That meant she was excited, right?

"That feels good," she purred.

"Alright," Lynn said, "no more."

Lincoln let out a disappointed breath. Leni pouted. "But, Lynn..."

"No more."

Leni stomped her foot and looked down at Lincoln. "Sorry, Lincy." She reached down, picked up her panties, and glared at Lynn. "You are so not fun."

Lynn stuck her tongue out, then cast a sidelong glance at Luan. "Oh, Lu," she warbled, "I have a good one for you." She looked at Lincoln: He was still kneeling, his chest rapidly expanding and contracting.

"What?" Luan asked.

"I want you," Lynn said, "to put Lincoln's dick in your mouth..."
