Author's Note: Hello!

I wanted to start out by saying THANK YOU to the amazing reviews and all the fic requests! Now, I've gotten a few requests to write a scene between Sam and Mercedes during The Quarterback and while I'm flattered, I honestly am not able to do that. I personally think that episode was written beautifully and I think of it more as Cory's episode than anything else, so the writing with the characters wouldn't be right. That probably didn't make any sense, but I hope you all understand!

Anyway, here's another fic request by Triple3JC - Rehearsal between Sam and Mercedes during Rocky Horror.

Sam had been jealous before, plenty of times. Whether it was when he was ten years old and became an older brother to Stacey and Stevie and felt his parents no longer paid him attention, or when he noticed his girlfriend, Quinn, giving slightly longing looks towards Finn Hudson almost every day.

But he had never been jealous of clothing before.

It seemed silly, to be jealous of a fabric, but here he was, desperately clenching and unclenching his fists, trying his best to keep them at his sides to refrain from tearing the clothes apart with his bare hands. He could just imagine the feel of the leather beneath his fingertips as he tore into it, ripping it apart at the seems. And the sheer-black top just above the bustier, damn.

Sam shook his head and quickly wiped the drool gathering at the corner of his lips. She was going to be the absolute death of him.

He tried his best to avoid her since seeing her in her costume for the first time. She kept approaching him, though, asking if he'd like to rehearse after school one day. He politely declined three times until one day, she flat out got in his face and demanded he rehearse with her or she was going to shove her Jordan's up his ass. Even that turned him on.

He arrived at her conveniently parent-free home on a Friday night. She was sporting leggings, ankle socks, and a loose shirt that hung off of one shoulder. He took quick note that he didn't see a bra strap on her bare shoulder and he had to pinch his thigh as hard as he could to avoid moaning out loud.

What was he doing? He needed to get his shit together. He had a girlfriend. He should not be thinking of someone else like this.

"Would you like something to eat or drink?" she offered as they entered her kitchen.

Sam ran a hand through his blonde locks, letting out a small breath. "Uh, no, thanks. I just ate." It was a flat-out lie. He could definitely eat, but it wasn't food that he wanted.

"Ya sure?" She raised her eyebrow curiously. "I have plenty of food. My mom made me three whole meals before she and my dad left for the Dentist Convention."

He shook his head. "I'm fine, really."

She smiled gently and then shrugged. "Well, then shall we head upstairs to start rehearsing?"

"Up-upstairs?" he stuttered, suddenly flushed. He thought they would rehearse in the living room or something, mutual ground. Upstairs meant bedroom. Bedroom meant bed. Bed meant-

"Yeah," she interrupted his thoughts. "I have all my music set up in my room. Unless, you want to rehearse somewhere else-"

"No!" he all but shouted and she took a step back, surprised at the outburst. Clearing his throat, "I mean, no. Upstairs is fine."

Mercedes looked at him oddly before she stalked out of the kitchen and towards the stairs just down the hall. Sam followed behind, but not too closely, afraid that his hands might betray him and touch her like he so desperately wanted.

Her room was purple with a large queen sized bed in the middle. The drapes on her windows were a lilac color and she had framed photos and posters of famous singers adorning her walls. There was a walk in closet next to the attached bathroom and a keyboard in the corner of the room next to her vanity and dresser. He noticed how big her house was before he was invited in, but he never really paid attention until this moment.

"So, I was thinking we could practice a few songs and work out some of the choreography Mike showed us today."

Sam looked at her as she sat down and began playing a tune on the piano. "Uhh, yeah, that sounds great."

Thirty minutes later, Sam had his hands in his pockets and was adjusting his erection as discreetly possible while Mercedes flitted about the room singing and dancing. All hell practically broke loose when she brushed her booty against his crotch and a strangled grunt escaped his lips. Mercedes stopped all movement and slowly turned around to take in Sam's appearance. She felt the bulge in his jeans and there was no denying the sound he made when she touched him.

"Sam?" she asked. "Are you... you know...?"

Sam's eyes were wide as saucers, his face a deep red. "I, uhh, I..." He placed his hands in front of his crotch and looked down ashamed.

"Really?" She sounded surprised. "I mean, I know I'm all kinds of hot, but I've never... Ya know, a guy has never... I mean..."

They both were at a loss for words for a few awkward moments. Sam finally sighed and gave up hiding his erection, placing his hands at his sides. "Listen, Mercedes, ever since I saw you in your costume I started to see you in a new light. Not that I never thought you were pretty, I've always thought that. But damn, you in that costume has had me wakin' up more than once in a cold sweat with a mess in my boxers."

Her eyebrows shot up at the confession and a smirk covered her face. "Oh really?" She took a slow step towards him and Sam audibly gulped. "What happened in these dreams?"

His body involuntarily shuddered at the seductive tones of her voice. "Mercedes," he breathed out. "I- I... Quinn..."

"Isn't putting out," she interrupted slyly. "I know that for a fact." Sam stared at her blankly, at a complete loss for words. Later, he would blame it on the fact that all the blood had drained from his head settled in his groin. She took advantage of his sudden silence, slinking up to him and pressing her breasts against his t-shirt clad chest. Her fingers hooked in the belt loops on his low-rise jeans and tugged, his hips colliding with her soft belly. Their height difference was almost laughable, but Sam couldn't help but think that they fit perfectly. "Tell me," she demanded simply. "What was I doing in these dreams?"

He gawked at her and blinked rapidly. "You, uhhh, you had your hand on my- you know -there..."

"Here?" She innocently placed her hand on his hip, her eyebrow cocked.

He shook his head. "Lower."

She slid her hand down and around to his ass, gripping it tightly. "Here?"

Sam bit back a groan, trying to keep his hands at his sides, but ultimately failing. He grabbed her wrist and dragged her hand to the bulge in his suddenly constricting jeans. "Oh," she gasped, a twinkle sparkling in her eyes. "Then what?"

He couldn't concentrate, too lost in the feeling of the slight pressure she had on his crotch. And then she started to slowly move her hand up and down and his eyes practically rolled back into his head. He was about to open his mouth and tell her what to do next when his cellphone rang loudly in his pocket. They both froze, her hand still cupping him through his jeans, his breathing slightly labored and her eyes wide and shocked. She pulled her hand back as he reached for his phone, letting out a curse when he saw the caller ID.

"Hello?" he answered, watching as Mercedes seemed to gather herself together. "I can't right now, Quinn." He winced when Mercedes froze, gazing at him with a mix of jealousy and regret in her eyes. "Listen, I'm not home right now. I'll call you later, okay? Yeah... Okay, bye." After minutes of awkward silence, Mercedes had led him out of her house and Sam cursed himself the entire way home.

They didn't speak for two whole days, which was surprisingly easy no matter the fact that they saw each other in Glee Club and in rehearsals after school. Neither knew how to bring up what happened, nor could they recall if it was just a dream. It wasn't until Mike pointed out that Sam probably should stop glaring daggers at her all the time that he realized just how much he still wanted her, awkwardness be damned.

When he pleaded for a different pair of shorts, it really didn't have much to do with the fact that he was afraid of showing nuttage, but more due to seeing Mercedes in her costume and having his obvious boner flop out to attention. After the disastrous dress rehearsal, when everyone was done changing into their normal clothes and heading out, Sam sneaked into the ladies dressing rooms. Mercedes was the only one left and he watched as she bent over to get her clothes out of her bag, presenting her fabulously rotund ass to him. He couldn't help but grab her hips and press himself against her.

Mercedes gasped and still her movements. She didn't need to turn around to know who it was. She stood up, purposefully grinding her ass against his erection as she did. "Sam..."

"You were sucking my cock," he blurted out throatily. At this, she whipped around to face him, her eyes full of confusion. "My dreams," he reminded her. "In my dreams, you were on your knees, my hands were tangled in your hair, and my cock was being sucked by your delicious mouth."

She bit her lip, letting out a whimper at the image he just provided her, but then she thought about Quinn and she sighed. "Sam, I want nothing more than to, you know, do that and a whole list of other things with you, but-"

"But what?" He pouted at her and she smiled.

"Well, first of all, there's about eighty bobby pins in my hair and it would take way too long to get them out so you could hold my hair while I sucked you off." He grunted and involuntarily thrust his hips into hers. Mercedes felt a liquid heat pool in her panties, but her face remained passive, amused at the most. "And second of all, you have Quinn." She watched as Sam quickly remembered his girlfriend and took a step back, keeping a distance between them. "If we were to do this, I want us to do it the right way."

He nodded at her, his expression softening as he ran a hand through his hair. "You're right."

She grinned at him before turning to gather her clothes. "Well, I gotta go. I'm meeting Kurt at the Coffee Bean."

"Yeah, me too. I promised Quinn I'd go shopping with her tonight."

Mercedes willed her face to not convey the jealousy that coursed through her, but she knew it did and Sam saw it right away. "Okay," she squeaked out. "I'll see you tomorrow, then."

Unable to stop himself, Sam leaned down and kissed her cheek before he smiled and walked out of the dressing room, feeling Mercedes' stare on his ass as he sauntered away.

He would definitely have her. One day...

A/N: OKAY, SO, not sure if this is how you wanted this to go, but this is what I wrote and I honestly could not go any further. I actually wrote most of this last week, but I got writer's block and I finally just cranked out whatever came to mind.

Sorry for the long wait in update! I hope everyone enjoyed their holidays.

Reviews are very much welcomed and keep sending those prompts!
