Shawn and Kendall Ch. 16

"But Marcey, I swear if you tell anyone!" Kendall spun to face her with a dire expression.

Marcey raised her hands in passivity, leaning backward.

"My lips are sealed," she giggled, "I just can't believe she was right."

Kendall's shoulders lowered as she breathed out, turning away from her.

"Me either..." She mumbled, "I hate how psychic she is."

"Um, I hate to break it to you," Marcey chuckled, "but it doesn't take a psychic to know something is going on with you two."

Kendall faced her with an alarmed expression, not realizing they had already looked so guilty.

"Was it really that obvious?" Kendall whined, her shoulders drooping.

Marcey nodded her head with a condescending grin. There had never been any genuine indicators that Shawn and Kendall were sleeping together until now, but Marcey could not deny that their jokes over the years weren't unwarranted. They had always shared a more comfortable level of touch than other siblings, and they remained inseparable since childhood. Both would go to war for each other, and the people around them inevitably drew their own conclusions. It was only natural to suspect something more-than-sibling-like was happening between them.

"How long?" Marcey snickered, entertained.

"A couple of weeks..." Kendall mumbled, "we just started doing stuff the weekend you two saw us at the club."

"Oh, shit!" Marcey giggled, smiling at her with fascination, "is it good?"

Kendall stared at her, confused by her laughter. She wasn't sure why Marcey was taking her fucked up secret so well, finally sighing and looking away in embarrassment.

"It's the best, Marcey," Kendall whined, covering her face, "there are no words in the English language to describe how insanely good it is."

Marcey quietly gasped with her hand over her mouth, struggling to subdue her intrigued giggling.

"But you cannot tell anyone!" Kendall's gaze shot back toward her, unamused by her laughter, "especially Grace!"

"Don't worry," Marcey scrunched against her playfully, pursing her lips, "I won't tell. Her being right doesn't make what she did okay. I'm on your side with that whole thing, so it's up to you if you wanna forgive Grace, and the only way she'll know is if you tell her."

Kendall turned to face her, looking into her eyes, relieved that Marcey agreed with her decision to end things with Grace. Marcey had always been far more level-headed, often being the voice of reason in their trio. She and Kendall had never fought or betrayed each other over the length of their friendship, and they told each other everything. But this was not Kendall's first fight with Grace. It just happened to be her last.

"Speaking of, how's he doing?" Marcey asked, looking Kendall over, knowing Grace had done a number on Shawn.

"He's fine," Kendall mumbled, looking away from her, "my brother's not a freak, Marcey. He just-"

"Kendall," Marcey interrupted her.

Kendall looked back at her, seeing her smirking.

"You don't have to defend the guy. Not from me."

Kendall analyzed Marcey for a moment, questioning how strangely unbothered she was.

"Why are you so okay with this?" Kendall asked, making a cynical face, "are you wearing a wire or something?"

She began prodding at Marcey, lifting her crop top and making her laugh. Marcey was ticklish, and Kendall occasionally tortured her.

"Stop!" Marcey cackled, guarding against Kendall's hands, "I'm not here to spy!"

"Why are you here, then?" Kendall asked, her smile fading away, "and more importantly, why aren't you freaking out?"

"You know," Marcey said, looking away and dangling her feet off the bed because of how short she was, "I told her I wouldn't do it."

"Do what?" Kendall asked.

"Get in your business," Marcey answered with a shrug, "she wanted me to help her dig around and catch you guys, but I said I wouldn't."

"When was this?" Kendall asked, already having an idea.

"The day she found the birth control in your mailbox," Marcey responded, "when she came back to the car, we both pretty much concluded you two were fucking."

Kendall's eyes wandered away, reflecting on what Grace said to Shawn the night before. It was crazy to think she had built an entire case against them in a single trip to Kendall's bathroom. Everything from matching his toothbrush to recognizing her clothes in front of Shawn's shower. She picked up on their behavior at the club, too. It bothered Kendall that Grace promised not to share what they discussed in the kitchen, only for Marcey to confirm she had broken that promise as soon as she returned to the car.

"She promised me before she left she wouldn't tell anyone..." Kendall closed her eyes, looking away in disappointment.

"Wait, you told her that morning?" Marcey leaned forward.

"Well, no," Kendall mumbled, "but I told her I was sleeping with someone. She said she wouldn't give back my birth control until I spilled the tea. But I made her promise not to tell anyone!"

"Not surprising," Marcey shook her head.

"What do you mean?" Kendall asked, giving her a concerned look.

"That's the thing," Marcey answered, "when I told her I wouldn't help her, she told me she'd drop it. That was clearly a lie."

Kendall continued listening to her, never hearing Marcey speak out against Grace.

"You know I got really mad and left when she told me what she did?" Marcey asked, giving Kendall a severe look.

"You did?" Kendall nervously asked.

Marcey nodded, kicking her feet over the edge of the bed and thinking about her younger brother.

"Kendall, I love Caleb," Marcey continued softly, "no, I don't want to have sex with him, and I know I've been a bitch to him in front of you guys, but he's still my brother. I would do anything for that annoying little dipshit."

A warm grin slowly formed on Kendall's face as Marcey empathized with her situation.

"And I'll be honest with you," Marcey sighed, "if Grace ever called him a freak, I would lose my shit on her."

"So you understand why I did what I did, then," Kendall quietly responded.

"Totally," Marcey nodded with a smirk, "Caleb and I are nowhere near as close as you two. I can only imagine how that made you feel."

"Um..." Kendall looked away awkwardly, fidgeting with her fingers, "I was there."

Marcey tilted her head with a confused look.

"When she came into his room," Kendall mumbled, embarrassed, "I was hiding. In his bathroom..."

Kendall's eyes nervously wandered back to Marcey, seeing her jaw drop as she gasped with shock.

"You mean you two were..." Marcey whispered, floored by Kendall's confession.

Kendall bit her lip and nodded, fighting to hold back her smile. Marcey covered her mouth with both hands, cackling wildly. She found Shawn and Kendall's relationship both thrilling and special. No part of her felt disgusted by their decision, knowing how close they were. Even if she did not resonate with their incestuous behavior, she still understood that they were free to do as they liked, and it was not the rest of the world's place to judge or damn them.

"Well..." Marcey said, observing Kendall with a cute smirk, "I guess if you're having fun. I thought your brother was pretty hot at the club, so I can see the appeal."

"I know, it's fucked up," Kendall sighed, "but it's hard to explain."

"Hey," Marcey raised her hand to stop her, "you don't have to go into all that. I believe you."

"Right, sorry," Kendall shook her head, knowing Marcey likely did not hunger for the details of how their obscure relationship began.

"Anyway," Marcey stood up, slipping her shoes back on, "I should go. I have to work a double tomorrow."

"Yuck," Kendall made a face, standing with her, "when are they going to stop working you into the ground?"

"Fuck if I know," Marcey shrugged, "but the money's good. I'll take it while it's here."

"Okay, just don't overdo it," Kendall rubbed her arm, looking her over nervously.

"Yeah, yeah," Marcey dismissed her with a sigh, approaching her with open arms.

Kendall embraced Marcey, holding her tightly, thankful to have a friend in this world who understood her situation.

"Thanks, Marce..." Kendall whispered with gratitude, "you're such an amazing friend."

"Uh-huh," Marcey chuckled, letting go and grinning at her.

"I mean it!" Kendall laughed, "and remember. No telling!"

"I know, I know," Marcey rolled her eyes, crossing her arms.

"Okay, good," Kendall deflated, trusting her.

"Wish I could find somebody to fuck me really good..." Marcey grumbled.

Kendall snickered through her nose, not believing her. Marcey was painfully cute with a great body and would never have issues getting someone to sleep with her. But she always talked about wanting sex without the intention of finding it. Marcey was not the type to hook up or sleep with just anyone. Her idea of sex was similar to Kendall's in that she only wanted to do it with someone special. But Marcey worked long hours serving at a restaurant in a nicer part of town and spent most of her free time occupied by photography, her favorite hobby, so she didn't date often. As a result, she had dry spells, only able to complain about not having as much sex as she wanted to her friends.

"Whatever," Kendall grinned, "you are so hot, and you know it. I'm sure it wouldn't be too hard."

"You'd be surprised," Marcey groaned, rolling her eyes.

"You mean to tell me these aren't doing it?" Kendall giggled, lifting her crop top and exposing Marcey's lovely, perky breasts.

Marcey huffed through her nose, letting her shoulders drop as Kendall exposed her breasts. Despite being smaller than Kendall, she had larger breasts and beautiful pink nipples.

"Apparently not!" Marcey snapped, "and I thought I had nice ones, too!"

"I could stare at these all night, Marcey," Kendall shook her head in awe, "I am so jealous of-"

Kendall's sentence was interrupted by her door flinging open, revealing Shawn mid-sentence in the doorway, wearing only boxers and a t-shirt.

"Hey, I think they're-"

His eyes finally met with Kendall and Marcey, immediately zeroing in on Marcey's breasts. Marcey ripped her shirt back down in a flash, saying nothing.

"... Asleep?" He awkwardly mumbled, his eyes darting back and forth between them in confusion.

"Outstanding..." Marcey grumbled at Kendall, giving her a look.

Kendall compressed her lips and struggled not to lose her mind. The chances of her door opening at the exact moment Marcey's breasts were out were so low she couldn't help but laugh.

"S- sorry, I didn't mean to..." Shawn mumbled, unsure what to do.

"Consider this your lucky day..." Marcey glared at him, heading for Kendall's window.

Kendall followed her, making sure she was able to climb out easily.

"Okay," Marcey sighed, squatting down and facing Kendall from the roof, "sounds like your folks are asleep. Bet I know what that means," she said, looking Shawn up and down.

"Ssshhh," Kendall shushed her, looking back at her brother, "remember, no telling. Promise me!"

"I promise," Marcey smirked with a nod.

"Okay, be careful," Kendall said, watching her climb back down.

Shawn approached Kendall as she closed her window back, still processing what he had walked in on. He never realized how nice Marcey's boobs were and admittedly couldn't stop thinking about them. She generally avoided clothing that revealed them, so it was Shawn's first time seeing so much of her. But his mind was even more occupied by the interaction he had just witnessed between them. It sounded like Marcey knew much more than she was supposed to.

"Um..." Shawn mumbled, scratching his head and pointing toward the window, "why do I get the feeling you told her-"

"Please don't get upset," Kendall spun to face him with a guilty look.

"You told her!?" Shawn raised his voice, his gaze bolting back and forth between Kendall and the window.

"I know, I know! I'm sorry!" Kendall hopped in place, "but listen! She's not gonna tell!"

"Kendall... The only way we could have guaranteed that was by not telling her!" Shawn snapped, grabbing her biceps, "what were you thinking!?"

Kendall looked into his eyes, knowing she had deliberately broken the rules to make herself feel better. The guilt had been so heavy lately, and she just wanted someone to listen to her.

"I'm sorry..." Her voice cracked, hating the feeling of Shawn being upset with her, "but I trust her. She came here just to make sure we were okay after what Grace did. I swear she won't say anything!"

Shawn sighed, lowering his grip from her arms, disliking that someone officially knew about them.

"We hope, anyway..." He grumbled.

A sudden tap on the window made their eyes bolt toward the sound. Marcey was squatting in front of it, staring at them. Kendall raced forward and opened it to let her in.

"There's one thing I forgot to mention," Marcey said, casually eyeballing Shawn from her crouched position.

They both stared at her, waiting for her to speak.

"Bradley helped Grace track your phone," she said, looking straight into Kendall's eyes.

Kendall turned her head toward Shawn, and they exchanged concerned looks. Their suspicions were accurate.

"Wait, how do you know that?" Kendall asked, looking back at her.

"She told me today," Marcey answered.

Kendall's eyes sank to the ground, processing the fact that Grace would go to such lengths because of her toxic, impulsive personality. It was a blow of the lowest variety, collaborating with her ex to expose them.

"Not trying to start any shit between you guys," Marcey continued, "just thought I'd let you know. You might wanna ditch that phone ASAP."

"Right... Thanks, Marce," Kendall mumbled.

"Alright. I'm leaving for real this time," Marcey smirked, gently moving Kendall's hair with her hand.

"'Kay," Kendall smiled.

"And you," Marcey looked past her at Shawn, causing him to straighten up, "don't you dare give her a hard time about telling me, got it?"

Shawn glanced at Kendall, wondering if Marcey saw how he reacted to her before knocking. Marcey impatiently raised her eyebrows, silently demanding a response from him.

"Uh, y- yeah. I won't," Shawn mumbled, shaking his head.

"Better not," Marcey mumbled, looking back at Kendall with a smile and rubbing her cheek.

They giggled at each other victoriously before Marcey turned around and left.

Kendall shut her window again, then turned to face Shawn. He stood in place, overwhelmed by everything. Regardless of how well she could be trusted, Shawn didn't feel good about Marcey knowing their secret. It was more bad news to learn that Bradley was teaming up with Grace to catch them. How long did they have until he showed his ugly mug, wanting a piece of them? Kendall strategically shut her door before their conversation went any further, not wanting their parents to stumble upon them.

"Okay," she sighed with her back to the door, then approached Shawn, "sorry about all that."

"Do you guys always look at each other naked?" Shawn asked, scratching his head.

"Not all the time," Kendall snickered, standing in front of him and looking him over, "we've just always wanted to trade butts and boobs."

"Huh?" Shawn mumbled, "that's a terrible idea! You're way hotter than she is."

"Hush, Dork!" Kendall snapped, "Marcey is so fucking cute! I'd kill to have her amazing boobs."

"But I like yours..." Shawn answered bashfully, softly running his hand along her hip.

"I know," Kendall smirked warmly at him, admiring his lust for her, "I like everything about you too."

"So... Basement?" Shawn smirked.

"Ugh, I thought you'd never ask," Kendall laughed, throwing her arms around his neck.

She stood on her toes, giving him a loud smooch and pressing her forehead against his. Shawn wrapped his arms around her lower back and held her tightly against him, never wanting to let go. They quietly left Kendall's room, making sure not to wake their parents. Sneaking through the house to get to the basement felt like reliving mischievous moments in their childhood as they held hands and tiptoed, opening and closing the door as silently as possible. They descended the steps painfully slow to prevent them from creaking, holding their breath until they were safely in front of the couch where everything began. They sat beside each other, and the light from the TV filled the room as Shawn started to put a movie on. Kendall grew more anxious by the second as he fooled around with the remote, desperately wanting to begin.

"Let's see... What should we watch?" Shawn whispered, scrolling through titles.

"Who cares?" Kendall huffed, removing her shirt and climbing on him, "just pick something!"

Shawn's eyes scaled her with surprise as she straddled him and wrapped her arms around his neck. He quickly selected the first movie on the screen, dropping the remote so they could start. Kendall pressed her mouth into his, feeling the euphoria of finally having him flowing through her veins. The repeated smooching of their kiss was loud and forceful. Kendall tasted her brother's mouth and played with his tongue to her heart's content, never tiring of the sensation. Shawn gripped her hips as they kissed relentlessly for several minutes. He could feel himself growing hard and throbbing against her burning-hot groin. When Kendall separated from him to come up for air, Shawn leaned forward and took her nipple into his mouth, sucking and swirling his tongue around it. She gasped with pleasure, her arms around his head, feeling the electricity shooting through her body. Shawn released from her with a loud suckle, gripping her lovely curves, mesmerized by her body. Kendall pressed into his collars, causing his back to hit the couch, and slowly stood up. She nestled between his knees, seeing his cock throb beneath his boxers. The sight of it injected her with lust, and she noticed the spot of precum near his waistband. Her hands eagerly pulled them down his legs, causing his cock to bounce against his belly.

"Fuck, you're so hard..." Kendall panted, using one hand to grip his shaft and the other to cup his balls.

The sight of his pulsating member was incredible, filling her with excitement. She was ready to take the lead and let him relax until they were both satisfied. Seeing his stomach huffing with anticipation turned her on immensely. She loved how hot and heavy his balls were, and their scent made her wonderfully dizzy. Kendall's mouth salivated at the sight and smell of him, unable to hold back any longer. She used her hand to point his cock straight toward her mouth, looking up at him with her gorgeous eyes. The look on his face was desperate and full of lust.

"Just relax," she whispered with a hungry smile, "you don't have to do anything."

Shawn's head fell back against the couch with a grunt as Kendall took him into her mouth. Her long, wet strokes were heavenly, and the tightness of her mouth stimulated his glans. Her mouth reached his base with each one, taking him all the way down her throat. Watching his entire length disappear down her throat repeatedly while she moaned with bliss drove Shawn wild. Her other hand gently cradled his balls, massaging them. She knew how to stimulate all of him when giving Shawn head, and he loved how openly she enjoyed it. Kendall released from him, leaving his shaft soaked and glistening with her saliva, and eagerly engulfed his balls. She loved their taste and smell, and feeling her brother squirm filled her with satisfaction. Her favorite thing to do was juggle them back and forth with light suction, massaging them with her tongue while stroking his shaft in her hand. Shawn always whimpered with pleasure when she played with his balls, letting Kendall know it was one of his weak spots. She giggled mischievously as she tasted them, soaking in his reactions. When she finally took her mouth off him, spit stretched from his balls to her chin as she exhaled. Her hot breath on his groin made Shawn tingle with pleasure.
