Shawn and Kendall Ch. 11-12

"Ready?" She whispered delicately, holding his tip against her burning-hot, soaking-wet entrance.

"Fuck..." Shawn huffed with his eyes closed and his hands gripping her hips.

Her sexy voice outside his ear gave him a shiver as he braced for the pleasure.

They moaned together as Kendall guided him inside her and lowered herself on him. His cock was the perfect fit for her insides, and she could feel every twitch and throb as she welcomed his entire length. Once Shawn was inside her, Kendall kissed him softly on his neck and collar, making him tremble and whimper. Shawn had never experienced such tender affection, and the feeling of her soft lips on his neck drove him wild. The smell of her hair and the warmth of her body against his was like a drug infecting his nerves.

As she sat up to begin moving, Kendall grabbed Shawn's hands from her hips and pulled them up to her chest. Shawn firmly cupped her lovely, perky breasts in his hands, feeling how hard her nipples were against his palms. He squeezed them, making her moan with delight as she rode him.

"Oh, fuck..." Shawn panted, groping her chest and feeling her insides work his cock as her hips moved.

"Yeah?" Kendall huffed with a smile, "feels different from down there, huh?"

Shawn nodded with his eyes clamped shut, panting, overtaken by pleasure.

"Here," Kendall suddenly stopped moving, "you're gonna love this."

When Shawn opened his eyes, Kendall was turning around to face away from him.

"Spread your legs apart," she said, wiggling her butt over him.

"Uh- like this?" Shawn stumbled, pointing his knees outward.

"Yeah, just like that," she answered, sliding her feet underneath his legs and rearing toward him.

"Whoa..." Shawn sighed, seeing his cock throbbing against her perfect, round ass.

"This is my favorite position," Kendall said with a sexy, confident tone.

"Mine too," Shawn mumbled in a trance, immediately recognizing it from watching so much porn.

Kendall giggled at his reaction, wiggling her butt playfully against his cock.

"Go ahead," she chirped, raising her butt to line him up with her entrance, "put it in."

Shawn grabbed his member and pressed it forward, lining his tip with her hole. Then, as Kendall felt him get into position, she reared backward and took him back inside her. Shawn groaned with pleasure as his head fell back against the bed. Her tight, hot place sucked him in and clamped around his throbbing shaft, and her soft, luscious butt against his groin was mindblowing. Shawn had seen this position in porn videos before but never thought he would get to try it himself, and all he could think about was how it was somehow leagues better than he had ever imagined.

Before his body could catch up, Kendall suddenly bounced against him, stroking his cock with her insides. She moaned as she took every inch of him into her with each bounce.

"Oh my God..." Shawn groaned as he watched her perfect ass smack against his groin and his soaked cock tunnel into her repeatedly.

The way her back arched and her hips moved made him feel like some sex goddess was spoiling him. The feeling of her insides stroking and sucking him in was otherworldy, and he could feel his orgasm approaching.

"Kendall..." He huffed desperately, feeling her milk him to climax with her thrusts.

Kendall moaned, slowing her strokes and looking back. She didn't want him to finish so soon and loved edging him with her insides.

"I'm gonna cum if you don't slow down," Shawn groaned, feeling her work his cock.

"Promise?" Kendall giggled, craving his load.

"No- Kendall, I'm really about to...!" Shawn panted as Kendall started bouncing against him again.

She smiled as her strokes picked up speed, wanting him to give her every last drop of him.

Shawn's toes curled as he struggled to resist her tight, wet insides wringing him out. The force of his impending orgasm nearly made him panic as she brought him past the point of no return. His breathing became erratic as he braced for Kendall to ride his load out, knowing it would be earth-shattering. Shawn could feel the pressure crawling up through his balls and shaft, squeezing the pillow behind his head and clutching his toes.

"Oh, fuck!" Shawn whimpered as his groin jutted forward.

"Ugh, yeah! Cum in me!" Kendall moaned, pressing herself hard against him and wiggling her butt.

With her hands pressed against the bed, Kendall took him as deep as possible, and that euphoric feeling of his cock pulsating inside her soon followed. She could hear Shawn shuddering with pleasure behind her as that addictive warmth from his hot seed filled her belly. The heat inside her grew with every violent twitch of his cock, and Kendall's body quaked from the feeling of being pumped full of her own brother's cum. The rush of committing the ultimate taboo flowed through her like a river of fire as her jaw dropped and her eyes began to roll. Her arms quivered, and the pleasure overwhelmed her.

"Fuuuuck," Kendall groaned, "why is that so hot!?"

Shawn's stomach violently expanded and deflated as he pumped every lost drop into her. It felt like her insides were extracting the cum straight from his balls.

"How do you keep making me cum like that?" He huffed, completely drained.

Kendall giggled as she slowly raised her butt, letting his cock fall out of her. She held herself there, letting Shawn's massive load drip out, and the sight of his cum pouring out of her made his veins flash with lust. Shawn couldn't believe the sheer volume that left his balls as his cum dripped back onto him.

"Mmm," Kendall whined, "I love how much you cum. That is seriously the best."

"Heh, it feels good for you, too, huh?" Shawn snickered, giving her ass a playful smack.

"Are you kidding me?" Kendall repositioned and flopped next to him, "I don't think 'good' is a good enough word!"

As she nestled against Shawn, her body throbbed with pleasure from trying out her favorite position on him. The feeling of his cum gushing inside her was addictive and thrilling, and she knew it was a dangerous thing to enjoy. Kendall understood no contraceptive was guaranteed, but she couldn't help herself. She wanted Shawn to pour his seed into her every time they had sex, regardless of the risks. The forbidden nature of their bond heightened her enjoyment of it like no other.

Shawn could feel his heartbeat calming as he held Kendall against him. The euphoric rush of pleasure from having his load worked out of him in such an erotic way still lingered in his nerves. He loved the sight of her butt bouncing against him. Though his mind was faintly worried about the risk of cumming inside her so often, Shawn, too, could not resist the urge to live out his fantasies. He shared the bliss of filling his sister to the brim with his seed, an act he had dreamt of for so much of his life.

"I think I knew somewhere deep down this whole time," Kendall said, rubbing his chest with her hand.

"What's that?" Shawn asked with his eyes closed, dosing off again.

"You know," she mumbled, "I knew it would just be... Good."

Shawn opened his eyes and looked down at her. Kendall stared at him as he collected his thoughts.

"You mean us having sex?" He asked.

Kendall nodded, chewing her lip and looking into his eyes.

"I thought you hadn't even considered it until that morning in the kitchen," Shawn chuckled.

"Okay, but, like..." Kendall stumbled, looking away from him.

"What?" Shawn laughed, nudging her with his arm.

"It's true," Kendall raised her voice, "I hadn't thought about us actually doing stuff until recently. But that doesn't mean I wasn't already attracted to you."

"Well, I am handsome," Shawn chuckled with sarcasm.

"You are, but that's not what I mean, you dork," Kendall giggled.

"So, if it wasn't my dashing good looks, was it my comprehensive knowledge of scary movies? Or perhaps my unmatched pancakes?"

When Shawn looked down at Kendall, she smirked silently at him. The look on her face was both warm and annoyed.

"You're such an idiot," she finally spoke, resting her head against his chest and scooting closer to him.

Shawn held her against him, feeling her soft, warm skin and finding security in her attraction to him. His lame jokes aside, he resonated with what Kendall was trying to say because he had felt the same thing toward her in his heart since they were young. He knew their sibling chemistry and unbreakable friendship would make having sex wonderfully natural.

"Okay. Your pancakes are really fucking good..." Kendall mumbled against his chest.

The two broke into laughter as they held each other.

A loud buzzing sound interrupted their moment, causing Kendall to look at the nightstand.

"Dammit," Kendall sighed, "it's too early for this."

A slight gasp followed when she reached for her phone. Shawn immediately looked at her, wondering what caused her panic.

"Uh- fuck, fuck! I need to get up!" Kendall jolted out of bed, running for the door.

"Where's the fire?" Shawn asked, not moving a muscle.

"Grace is on her way here!" Kendall yelled, unlocking the door and soring down the hall.

"Shit! Why!?" Shawn rolled out of bed, nearly tripping over his clothes as he raced after her.

"Here," Kendall handed him his toothbrush as she frantically brushed her teeth.

"How close is she?" Shawn asked, squeezing toothpaste onto his brush.

"Ionno," Kendall spat and rinsed her mouth with a panicked tone, "her text said she was on her way. We need to hurry!"

Shawn sighed with frustration as he brushed, disliking that their morning together was being interrupted again.

The two blasted through their shower together, imagining the horror of Grace showing up and smelling the sex on them because, unfortunately, Grace was Kendall's nosiest friend and habitually showed up with insufficient notice on some weekends. Dropping by was usually not a problem because Grace typically did not interact with Shawn often, but after last night's events, they needed to eliminate all suspicion. Furthermore, Kendall had an unpleasant feeling that Grace would want to see Shawn again after how she acted toward him at the club.

"Okay," Kendall sighed, drying her hair with a towel, "so obviously, Grace is nosy."

"Most good friends are," Shawn replied, sliding fresh boxers on.

"I do love her," Kendall said, reaching for her bra, "but sometimes she's too much."

"Are you worried she's gonna ask about last night?" Shawn asked.

"Terrified," Kendall groaned.

"Hey, don't worry," Shawn reassured her, "they didn't actually see anything shady, did they?"

Kendall looked him up and down with a slight smirk as she hooked her bra.

"I hate to break it to you," she smiled, "but me dancing on you is pretty shady."

"Hm," Shawn shrugged, buttoning his shorts, "well, I sure liked it."

"Me too," Kendall giggled, wrapping her arms around him and giving him a peck on the lips, "but they don't understand. You know that."

"I mean, it's not that weird, is it?" Shawn asked.

"Mhm," Kendall grinned and nodded, "pretty weird."

Shawn sighed through his nose, rolling his eyes.

"I know, I know," Kendall consoled him, "come on. Let's go."

"They're just jealous..." Shawn grumbled as Kendall locked arms with him, leading him out the door.

"Probably," Kendall laughed as they made their way downstairs.

"Shit," Shawn grunted as he opened the fridge, "I'm out of coffee."

"Can't you just make a pot? There's a whole bag in the cabinet," Kendall responded, shoveling down a bowl of cereal.

"No!" Shawn snapped, "I don't like hot coffee. It's too-"

"Yeah, yeah," Kendall interrupted him, waving her hand, "it's too acidic!" She mocked him.

Shawn slammed the fridge shut, disliking her impersonation of him. Kendall knew why he preferred cold brew and still picked at him about it. She giggled through her nose with her mouth full after seeing the look on his face.

"Laugh it up," Shawn groaned, walking past her and delivering a hard smack to her ass that rung through the kitchen.

"Ow!" Kendall yelled, "there's a time and place, idiot!"

"How about as soon as Grace leaves?" Shawn answered, turning his console on to fire up a video game.

Kendall wandered into the living room and stood behind the couch with her bowl of cereal to watch him fight while she waited.

"If I can get her out quick enough, sure," she agreed, taking another bite, "speaking of, where the hell is she?"

Shawn shrugged, sitting on the couch and clicking through the menus of his game to start fighting.

The moment Kendall questioned it, a knock thudded at the front door.

"Showtime," Shawn mumbled, ready to be as distant as possible.

"Yeah..." Kendall sighed stressfully, setting down her bowl and approaching the door.

"Well, good morning!" Grace sang as Kendall opened the door to let her in.

"Hey!" Kendall forced herself to smile.

Grace wore a black leather jacket over a white t-shirt with jean shorts, fishnet leggings, and sneakers. Her jet-black hair was permed and wild. Anyone could discern from her appearance alone that she was feisty and energetic. For as long as Kendall had known her, Grace was a troublemaker and a fighter. But Kendall loved her and cherished their friendship. They had gotten into trouble countless times because of Grace's rebellious influence, creating a powerful bond with crazy memories.

The two wandered toward the kitchen, and Grace noticed Shawn on the couch.

"Hi, Shaaaawn," she greeted him with a deliberate tone.

"Yo," he raised his hand, not looking away from the screen.

The next moment, Grace was leaning on her forearms on the back of the couch with her face uncomfortably close to Shawn's.

"How was last night?" She asked with a grin.

Shawn leaned away from her, smelling the cigarettes on her breath, disliking her lack of boundaries.

"Um... It was fine," he answered, his eyes wandering her face.

Grace smiled at him, studying his expression and confirming her suspicions that he was more handsome than she thought. Shawn's eyes wandered down to her red lipstick and white teeth. Her dark eyes were deep and curious. Of course, Grace was beautiful, but Shawn disliked the smell of cigarettes and anyone being in his bubble.

"Good," she answered swiftly before standing up and bolting toward the kitchen.

Shawn lightly shook his head, wondering how Kendall spent so much time around someone so unhinged.

"So, what's new with you?" Grace asked, grabbing a bag of pretzels off the counter and shoveling a handful into her mouth, "anything exciting?"

Kendall shrugged as she finished a gulp of water from her glass, not wanting to give Grace any doorways into her new situation with Shawn.

"Just working and staying busy. You know," Kendall mumbled.

"Staying busy, huh?" Grace asked with a raised eyebrow, chewing pretzels.

"Yup," Kendall answered, deliberately staying vague.

There was an odd silence between them as Grace folded the bag and set it back on the counter.

"You must be," she responded, reaching into her jacket and revealing a small packet.

Kendall immediately recognized the packet, realizing it was her birth control that came in the mail every month.

"Where did you get that?" Kendall asked, slightly alarmed.

"It was in your mailbox," Grace casually answered.

"Grace!" Kendall fired out, "why did you go through our mail!? Give that back!"

Kendall felt mortified that her friend had rummaged through her personal belongings, and her mind raced with ideas to prevent Grace from asking too many questions. But, over the years, Kendall had begun to realize that Grace was a natural-born detective, and it was nearly impossible to hide anything she was interested in from her. Moreover, fooling Grace into believing nothing was happening with Shawn grew more challenging by the day because if Grace wanted to know about something, she always found a way.

"Ah-ah!" Grace held the packet behind her back, preventing Kendall from taking it, "I wanna know about him!"

"Who!?" Kendall yelled, trying to take the packet from behind her.

Grace playfully sprinted to the other side of the island to evade Kendall, refusing to give it to her.

"The guy you're sleeping with, obviously!" She laughed, craving the details of Kendall's love life.

"But I'm not!" Kendall whined, "please just give it back!"

"Not without the tea," Grace flicked her eyebrow, leaning on the island.

Kendall finally sighed through her nose, lowering her shoulders. She knew there was no other way out of this talk. All she could do now was tell Grace what she wanted to hear without revealing that it was Shawn.

"Fine..." She mumbled quietly, holding her hand out.

Grace's eyes shot open, and she sprinted around the island, smacking the packet into Kendall's hand.

"No way!" Grace yelled with a giant smile, "you are having sex with someone!"

Kendall violently shooshed her, frantically waving her hands at Grace's face.

"My brother's right there!" She hissed, not wanting Shawn to hear them.

"So?" Grace shrugged, "I thought he was your best friend. You guys don't talk about sex?"

"Um... No?" Kendall answered with an attitude, "he doesn't need to know about that stuff. God, you really are an only child!"

"Hey, Shawn!" Grace called out, making a cynical face at Kendall, "our girl talk isn't bothering you, is it?"

"Not listening, kinda busy," Shawn answered plainly, mashing the buttons on his controller.

Grace gave Kendall a victorious smirk and flicked her head, eliminating her excuse to avoid the discussion.

Kendall glanced over at Shawn, feeling the weight in her heart as she thought about how badly she wanted the world to accept them. She thought about how, in a perfect world, nobody would judge her for loving him. He was intelligent, polite, honest, and attractive. But Shawn was her brother, and this world is imperfect, forcing her to lie to her best friend to protect that love.

Kendall tugged Grace's arm and pulled her to the other side of the kitchen, away from Shawn's ears.

"Okay," Kendall sighed, tucking her hair behind her ear, "just don't tell anyone else about this."

"Deal!" Grace replied excitedly.

"So... Yeah, I'm sleeping with someone," Kendall mumbled awkwardly, scratching her head.

"What does he look like?" Grace asked, "do I know him? How long have you guys been fucking? Show me a picture!"

"No," Kendall giggled as Grace drilled into her, "you don't know him, I'm not showing him to you, and if you must know, we just had sex for the first time last night."

Grace's face lit up with excitement as Kendall explained her situation.

"Why can't I see him?" Grace prodded further, "is he ugly or something?"

"No," Kendall mumbled, looking away.

"So he's hot?" Grace asked, smiling at her.

"Insanely..." Kendall answered with a nervous smirk, thinking about Shawn.

Grace's jaw dropped, thirsting for more information on Kendall's mysterious new partner.

"Okay," Grace laughed, "so he's new, he's not, and what else? Is it serious?"

"Um..." Kendall rubbed the back of her neck, evading the question.

"Did you let him?" Grace asked with a suggestive tone, waving Kendall's birth control near their faces.

"Let him what?" Kendall asked, puzzled.

"You know, that thing you like," Grace raised her eyebrow, looking down at Kendall's lower half.

Kendall compressed her lips and made a guilty face as her mind replayed the sensation of Shawn cumming inside her. Grace's mouth gaped open, and her eyes widened as Kendall's expression gave her away.

"You slut!" Grace smiled, giving Kendall's arm a playful shove.

Kendall shooshed her, trying to hold in her cackling.
