Sex in AU

A/N: That typo was too good to fix....

Dean and Cas were boyfriends. Had been since middle school.

Sure, they had different social circles. Dean was a football player, and Cas was a general bookworm who sold his social life away the day he joined the math team, but they didn't care. It just meant that they ate lunch at different tables.

They were juniors in high school, and prom season was in full swing. Promposal after Promposal were covering the school, each more extravagant then the last.

Frankly, Cas didn't like promposals. He thought they were embarrassing. He and Dean had already agreed to go to prom together, even if neither of them had officially asked the other. They saw no reason too. It was just obvious to both of them that they'd be going with each other.

There was no need for a promposal. Until Dean's football buddies brought it up at lunch.

"Did you hear about Crowley's promposal?" Benny questioned.

"No," Dean admitted. "What happened?"

"Apparently, he wrote 'Abbie, will you go to prom with me?' in BLOOD in the girl's bathroom."

"....Human blood?"

"I have no idea. Jo said it was pig's blood from the ones the Anatomy classes are dissecting, but with Crowley you can never be sure."

"What did Abbie say?"

"Yes, of course. Those weirdos were made for each other, even if they fight all the time."

"Yeah," Dean offered. "I'm glad I'm not like that. No fights for me, thank you. Just smooth sailing with my Cas."

"Then how come you haven't asked him to prom yet?"

"Don't need to. We know we're going with each other."

"Yeah, but promposals are fun! It's a way for you to show the whole school how much Cas means to you- wouldn't you want to do that?"

"Well... Cas thinks they're cheesy, and I wouldn't want to embarrass him..."

"He wouldn't think your promposal was cheesy. He likes you too much. He'd think it's sweet and be extremely embarrassed in a good way." Dean glanced across the cafeteria to where Cas was sitting, laughing with Charlie and Garth.

"....You think so?" He asked.

"I know so." Benny confirmed. "Go for it!" Dean thought for a moment, and then got up from the table. Benny and the other football players freaked out.

"Oh my god, he's actually gonna do it." Michael offered.

"This is gonna be great!" Ash declared. Benny started recording it.

"I ship it so much!" Lucifer proclaimed.

"Luci, you're fangirl is showing." Michael warned.

"Fuck off, mistress."

"Aaaaand, Satan's back."

"Guys, shut up!" Ash yelled at them, and they craned their necks towards the nerds table to try and hear what Dean was saying.

"Hey guys," Dean started casually.

"Hello Dean," Cas offered, smiling at the sight of his boyfriend.

"Hey there Subway," Charlie commented. Dean raised an eyebrow in confusion, and Jo and Charlie burst out laughing.

"Don't ask." Cas insisted.

"Well, I won't ask about THAT," Dean agreed. "But I do have to ask you something."

"Shoot," Cas replied. 

And then Dean climbed on the lunch table.

"Oh my god," Charlie's eyes widened. Cas's eyes widened too.

"What are you do-" Cas started, but Dean cut him off.

"CASTIEL JAMES NOVAK," Dean proclaimed, dropping dramatically onto one knee in the the table. The rest of the cafeteria had gone dead silent, watching. "Love of my life!" Cas's face went bright red. "My darling blue eyed angel, would you do me the honor of letting me escort you to the promenade?" 

Cas's face was the color of a stop sign, but he was grinning wildly.

"Did he really just say promenade?" Charlie whispered.

"Dean's classy like that, so yeah." Jo whispered back. The entire cafeteria looked expectantly at Cas.

"Okay," Cas said sheepishly, smiling. 

"Yes?" Dean questioned. Cas nodded.

"Yes." 

"SUCCESS!" Dean bellowed before stepping off the table and pulling Cas in for a kiss. The kids of the cafeteria cheered.

"Did you get that all on video?" Lucifer demanded.

"Yep!" Benny insisted.

"Send me a copy," Michael begged.

"We're playing that at their wedding." Lucifer declared.

"Since when are they getting married?" Ash questioned.

"Since we said so." Lucifer offered. "I'll make them."

"You can't force two people to get married-"

"Bullshit, I'm Satan. I do what I want."

"It's best not to argue with him." Michael warned.

"You heard my mistress."

"Luc, I would appreciate it if you stopped called me your mistress."

"As you wish, Mike-stress."

"....That's worse."

"No, it's perfect."

******

Now that Dean and Cas were officially going to prom together, Charlie and Jo organized the next order of business.

Outfits.

"Charlie, I have a suit-" Dean began.

"NO, you DON'T," Charlie retorted. "Not one fit for Cas on prom. So you're going dress shopping with Jo on Saturday, and you're going to find a new suit, and you're going to make sure my girlfriend finds a dress that makes her looks beautiful, and you're going to LIKE IT."

"Charlie, remember how we talked about how you shouldn't threaten everybody with everything?"

"FUCK OFF AND BUY A DRESS TO IMPRESS YOUR BOYFRIEND, DEAN." Dean laughed.

"This is why you're my favorite."

"Can I tell Jo that? We have an ongoing bet about it."

"No, you can't."

"You're no fun. No wonder you're still a virgin."

"Charlie!" 

"What? It's prom time, Dean, live a little!"

"You are so gross."

"No, I'm just a fangirl. Now stay home on Friday night or else, kay?"

"Why?"

"Cause I'm taking your boyfriend out for dress shopping and mani pedis."

"See, this is why I wanted to go shopping with you."

"Yeah, but Cas would never survive if he were left alone with Jo."

"Oh dear god, no he would not."

"Exactly. I've designed the whole shopping trips to avoid any casualties. As long as Jo doesn't murder any shopkeepers, we should be good."

"I'll try to keep the murder to a minimum."

"....I like that line. I'm gonna use that."

****

So Charlie and Cas went to the mall, searching various shops for suits and dresses before finally settling in a small boutique that specialized in prom attire.

Charlie let out a wolf whistle as Cas stepped out of the dressing room.

"Looking sharp, Cas." She commented. It was a simple black suit, with a green tie that Cas knew for a fact matched Dean's eyes.

"Do you think Dean will like it?" He questioned.

"If any part of him is attracted to you, he'll be like putty in your hands in that thing."

"That's an odd way to put it."

"What about this- if I was a straight girl, I'd be drooling."

"Better." Cas nodded. "Okay, your turn."

Charlie took a lot longer, because montages, and because the redhead could not decide on a good dress.

"Charles, come on," Cas whined. "You know you're gonna look great no matter what you wear!"

"NO!" Charlie retorted, calling from the dressing room. "It has to be perfect. I want to leave Jo speechless."

"You're showing up in a dress, that'll make her speechless enough." Charlie and Jo hardly ever wore dresses. 

"No, I wore a dress three times this year. Jo in a dress will make me lose my mind, so I have to find something that will make her just as speechless as I will be."

"Well, what dress do you have on now?"

"Um....."

"Let's see it, Charlie." She sighed, but reluctantly stepped out of the dressing room. Cas raised his eyebrows.

Charlie was in a knee length blue dress that somehow matched perfectly with her fiery hair. It was silky and was by far the best thing Cas had ever seen her in.

"....It's hideous, isn't it?" Charlie concluded from the silence.

"It's...." Cas offered, stunned. "Hot damn." Charlie paused.

"Really?" She glanced in the mirror.

"Holy shit, Charles. I wanna send a picture to Garth and get a straight guy's opinion."

"Garth is too innocent for this."

"Yeah, well I don't want to risk Dean drooling over you, so he's not getting a say in this one."

"Dean;s gay, dude."

"Bi, and that means Lisa has a chance, and that means I need to keep him on the gay side as much as I can."

"Then just sleep with him or something. Easy fix." Cas stopped. He hadn't quite considered that idea before. Charlie seemed to brush off the thought casually, so Cas decided not to let it go to his head.

Charlie bought the blue dress, needless to say, and Cas got his suit.

How was shopping? Dean texted him later.

Good, he replied. Make sure Jo gets a dress that matches blue.

What kind of blue, like your eyes, or like really dark blue?

More like turquoise.

Got it..... Can I see your suit?

Hell no.

Awwwww

You'll see it on prom night, mister.

******

Prom night. The idea of it was working through Dean's mind.

He knew what stereotypically happened on prom night once the dance was over. Cliche movies with cars at Make out point came to mind.

Charlie's words also lingered in his head. 

"It's prom time, Dean. Live a little!"

He and Cas had been dating for awhile....

But they'd never discussed, well, THAT.

But prom night was unpredictable. Who knew what would happen when it finally rolled around?

Similar thoughts were also swirling around Cas's mind.

He hadn't really thought about sleeping with Dean before.

Well, no, that was a total lie. He'd definitely thought about it.

But he never thought about it actually happening. He and Dean never talked about that kind of thing before.

Would Dean even want to sleep with him?

That was a stupid question, Cas thought. Dean was a hormonal teenage boy. Of course he would want to sleep with him. It was the same reason that Cas wanted to sleep with Dean.

Who knew what would happen, he decided. It was better to just let prom night run its course. He'd know what to do when anything happened.

If anything happened.

*****

Prom ran from seven to ten at the gym at Lawrence High, so Cas and Dean met up before hand because parents always want stupid prom pictures of their kids for unknown reasons.

So when the doorbell rang promptly at 6:30, Dean knew exactly who was at the door.

"I'll get it!" He yelled, heading down the stairs.

"Uh, NO," Sam objected. "You get back up there. We're doing the whole prom reveal thing right, and you're not going to mess it up!" Dean rolled his eyes, but obliged. Sam and his stupid cliches.

So Sam opened the door, only to find Cas waiting.

"Snazzy," Sam commented. "Come on in," Mary was already waiting with her camera.

"Well don't you look handsome," She smiled. "Okay Dean, you're allowed to come downstairs now!"

"Figured we'd do the stereotypical prom reveal." Sam offered.

"Okay," Cas agreed, smiling. And then Dean walked down the stairs, fit in a suit.

Cas had never seen Dean in a real suit before.

The room temperature seemed to go up at least ten degrees after Dean entered the room though.

"Woah," Cas whispered.

"Woah yourself," Dean smirked, eyeing Cas. He knew Cas looked good when he dressed up, but damn.

"Boys, look over here!" Mary ordered. "I want some pictures!" They rolled their eyes, but posed for all of Mary's picture desires before she finally let them escape.

Dean drove them to prom in his beloved Impala, and they met up with Jo and Charlie just outside the gym where prom was held.

"Oh my gosh, you two look like awesome!" Jo declared.

"It's like John Wick and James Bond had a crossover," Charlie declared. The boys exchanged a glance.

"Dibs on John Wick," Dean declared.

"Well no duh." Cas offered. "Guess that makes me 007."

"You could pull it off."

"Hell yeah I can."

*******

The prom was what they had expected it to be. Loud music, dancing people everywhere, the occasional teacher chaperone making sure that nobody was spiking the punch (although Crowley had his ways), a pitiful photo booth in the back and some snacks and drinks.

At least, Dean thought as an Aerosmith song started up, they had good taste in music.

He and Cas danced nearly the whole time, jumping and laughing, swaying and occasionally stopping to down a cup of punch.

And then it came time to crown the Prom King and Queen. There had been polls for it set up all week, and Lawrence High was small enough that they didn't do nominations. Whoever had the most votes won, and the popular people always won.

So it was no surprise to anyone that Lisa Braeden was named the Prom Queen, although Dean and Cas could tell that Charlie was disappointed.

"Don't worry, babe," Jo assured her. "You're the only Prom Queen in my book." Charlie grinned.

"Can I have a crown?"

"You have a flower crown."

"That's the best kind."

"I know."

"And our Prom King is," The principal declared dramatically. "....Dean Winchester!"

"Wait what?" Dean said in surprise.

"Oh my gosh, Dean!!!" Charlie shrieked with delight. Dean looked confused.

"Go, go on stage!" Cas urged him, nudging him forward. So Dean went on stage and smiled and they put a crown on his head. Lisa seems defiantly proud of the fact that she was Queen, and he was King.

But that was Lisa; always the annoying bitch.

"As tradition has it," The principal went on. "The King and Queen are to share a dance together."

But it was prom night. The night you were supposed to have fun.

A night that Dean was basically promised he wouldn't have to deal with anyone like Lisa.

So as the Prom Queen smiled broadly and waited, Dean only smirked and shook his head, a great idea forming in his mind.

"Nah," He offered, stepping off the stage. 

"What-" The principal started, as Dean walked over to his friends.

"I'd rather dance with the true Prom Queen, thank you very much!" Dean declared, holding out a hand to Charlie.

The redhead graciously accepted, and they danced, a quiet fuck you to Lisa Braeden. 

Dean gave Charlie the crown too, because he thought she deserved it more then he did.

"That was really sweet," Cas insisted later.

"I know," Dean shrugged. "I just thought Charlie deserved it more."

"She did." Cas agreed. "And look at her." They glanced over at Jo and Charlie, who were spinning around and laughing, the crown resting firmly on Charlie's head.

"Perfect." Dean commented.

"A perfect prom." Cas proclaimed, leaning in and pressing a kiss to Dean's lips. Dean grinned and kissed him back.

******

Cas, Dean, Charlie, and Jo stumbled out of the gym, high on adrenaline and drunk on laughter. They could barely walk straight, a fact that make total sense seeing as they were all gay.

"You gals need a ride?" Dean asked.

"Nah," Jo insisted. "I snagged my Mom's car, we're good!"

"DRIVE SAFELY!" Charlie yelled at them. "I don't want any cliche fanfiction car crashes with ridiculous comas, okay?" 

"Okay!" Dean and Cas replied. They stumbled back to Dean's car, laughing and grinning like idiots.

They reached the car, and Cas was pressed up against the door, his lips locked with Dean's, laughter fading and replaced with a sense of lust.

At some point, Dean got the car door open, and then they were making out in the backseat of Dean's Impala. Cas was laying on the seat, and Dean hovered over him as Cas's wove his fingers through Dean's hair.

Lips moved toward necks, hands started to roam, and shirts were unbuttoned.

And somewhere, in the back of Cas's mind, a little alarm started going off.

This was the exact cliche prom night. A first time, in the back seat of a car in the dark.

And while Cas had nothing against the idea, especially when Dean was leaving hickeys on his neck and his hands were moving and everything felt so right, Cas just couldn't help but get the feeling that this isn't what he wanted his first time to be.

He wanted something romantic, on a bed, for one thing. He knew Dean's perfect idea of a romantic night would be in the back of this car, but it wasn't Cas's.

Cas didn't want the cliche prom night. 

Cas wanted something more meaningful then that.

And so, as Dean slipped his hand under the waistband of Cas's pants, Cas's hand shot out and grabbed Dean's wrist, stopping him as his breath hitched and he let out a soft "No."

Dean paused, staring at Cas, trying to read the conflicting emotions in his boyfriend's eyes. The conflict of desire and fear, want and need. Cas looked a little panicked, unsure, and slightly fearful of what Dean might do next.

Slowly, Dean moved his hand away, and Cas let go of his wrist. Dean hesitated a moment, and then pressed a kiss to Cas's lips. His hands didn't wander lower again.

And then a loud, obnoxious ringtone rudely interrupted them. Dean sat up with a groan and dug around for his phone, frowning at the caller ID and then answering.

"Hey Jo," He offered, sitting back. Cas sat up, feeling slightly embarrassed. 

Had he been wrong to shy away from Dean? What if Dean interpreted it the wrong way, or he didn't understand?

What if he had just messed up everything with one little word?

"Yeah, okay," Dean said into the phone. "We'll be there." He hung up. "Charlie and Jo are having a prom after party at the Roadhouse- wanna go?"

"Sure," Cas forced a smile. Dean grinned at him, located his shirt, and then climbed into the front seat. Cas followed suit, fixing the buttons on his shirt.

"Your collar's all messed up," Dean commented. "Here," He leaned over, fixing it, and Cas relaxed slightly. Maybe he was just overreacting. Maybe Dean didn't think anything of his refusal.

....Or maybe he was roiling with rage underneath a calm surface. With Dean you could never be sure.

The ride to the Roadhouse was quiet.

"Dean," Cas started finally, figuring he might as well bring it up. "I'm sorry about, you know, pushing you away and everything..."

"You don't have to apologize for that," Dean said instantly. "You weren't comfortable, and you did something about it. That's what you're supposed to do."

"And you're not, I dunno, mad?"

"Mad?" Dean echoed. "Why would I be mad? If anything, I'm a little ticked off at myself for making you feel uncomfortable, but I'd never be mad at you."

"It's not that I was uncomfortable," Cas tried to explain. "It just... It didn't feel right. Not that you didn't feel right- you always feel right- but I just didn't want some cliche prom night in the back of your car, not that I have anything against your car, I know how much you love it, but-"

"Cas," Dean cut him off, raising his eyebrows. "Calm down. I understand." Cas sighed in relief.

"Thank you."

"Course." They stopped in the crowded parking lot of the Roadhouse. "Now let's go see how much trouble Jo's gonna be in when Ellen gets home, kay?"

"Okay," Cas smiled.

****

The Roadhouse was a disaster.

Jo was totally going to die when her mother came home.

There were teens everywhere, playing pool, blasting music, arguing. Tables and chairs were discarded, flipped, or scrapped along the floor, and Dean was pretty sure that Crowley and the more shadier kids were doing lines of cocaine in the back. The Roadhouse alcohol supply had been well raided, and there were people dancing with beers or doing shots off each other's stomachs. Jo and Charlie were dancing on the bar, and from the looks of it, Jo had definitely snuck them into the Roadhouse's secret stash of expensive, well aged liquor that hit you hard.

"Oh my god," Cas declared as they walked in.

"Wow." Dean commented. They headed over to the bar, just as Charlie slipped off it. Dean caught her quickly and the redhead let out a screech.

"Oh my god, I was gonna die!" She declared.

"DEAN!" Jo bellowed. "CASSIE! Welcome!!"

"You're drunk, Jo." Dean proclaimed.

"No," Jo objected. "I'm very buzzed, but not drunk. And if I am, then it's all her fault!" She pointed at Charlie, who giggled and accepted the blame.

"I let her do shots off me," Charlie laughed. "Off my forehead, off my stomach, off my-"

"OKAY," Dean declared. "Jo, you know your mother is going to kill you for this, right?"

"Well no shit, Sherlock." 

"Fuck you, Watson!" Charlie yelled back.

"Sherlock already did that." Cas said slyly.

"Cassie!" Charlie said in delight. "You need a drink!"

"No, he does not." Dean insisted.

"YES HE DOES," Charlie retorted. "And so do you, mister! Imma get my boys some drinks- what do you like, Cas, malt liquor? You look like a white wine spritzer guy, if I'm being honest, but I don't know what that is, so you'll have to settle for tequila." She wandered away, taking Cas with her.

"This was a bad idea." Jo offered.

"You think?" Dean questioned.

"Lighten up, Dean," Jo whined. "Get that twist out of your panties. Have a beer."

"I have to drive home, Jo."

"One beer's not gonna kill ya. Three might, but one's fine."

Dean sighed. It was gonna be a long night.

*****

Three hours later, Cas was lying shirtless on a table, and Dean was doing body shots of tequila off him, because why the hell not. 

The party seemed to have died down a little, since it was past midnight, and not everyone felt like breaking their curfew.

Charlie and Jo were splitting a water as they sat on the bar, debating how screwed Jo was when Ellen discovered that a good majority of the Roadhouse's liquor was gone.

"My mother is going to kill me," Dean declared. His curfew was midnight, and Cas's was 11:30. They were way late already.

"I don't even care what my parents will do," Cas insisted. 

"We should go home," Dean admitted.

"Yeah," Cas agreed.

"No way," Jo called from the bar. "You two are too wasted for driving. You're staying here."

"But-" Dean started.

"No buts!" Jo proclaimed. "If you're parents yell at you, then just tell them you witnessed a murder."

"Who's murder?" Cas questioned.

"Mine. When my mother shows up." Jo proclaimed. "There's a guest room above the bar, you can pass out there. Don't die."

"Yes ma'am." Dean rolled his eyes, and they trudged upstairs to the guest room and flopped down on the bed.

"You know," Cas commented. "Some people get really drunk, and then they have sex."

"I don't get that," Dean admitted. "Cuz I think I'm pretty drunk,"

"You are,"

"Yeah, and I really don't want to hook up with you right now, and that is not normal."

"I just wanna sleep."

"Me too."

"M'kay. G'night then."

"G'night Cas."

They both lay awake on the bed, tired, but unable to fall asleep.

"Hey Dean?" Cas finally asked.

"Yeah?"

"Are you drunk enough that, if we hooked up, you wouldn't remember?"

".....No."

"....Okay."

******

It turned out that Cas didn't get the cliche prom night first time. Instead, he got a buzzed first time, where Dean and Cas weren't really sure what they were doing, but something seemed right.

They tried it again the next morning, and decided that the half drunk failed attempt wouldn't count.

Prom night was one to remember, but what Dean and Cas really would never forget was the curse words that would echo from Ellen Harvelle's mouth when she came home and discovered a trashed Roadhouse with missing booze, scratched floors, and a pair of naked, hungover, gay teenagers upstairs in the guest room.

Jo Harvelle had intelligently decided to lock herself in the basement, just in case.

Prom certainly was fun.
