AN: After spending days reading Destiel fics, I finally decide to join the club and write one myself. I hope it's not too terrible, please tell me what you think (:

Dean Winchester sighed loudly and looked at the unopened bottle of beer balancing on his stomach. He was alone at Bobby Singer's house after Bobby and Sam had gone on a hunt without him. He wasn't bothered by it at all, he and Sam were having too many arguments to be around each other for long periods of time, so elected to stay behind. However, Sam and Bobby had been gone for a few days and Dean already used up all of his fun quota, nothing brought him joy, he couldn't even be bothered to drink. He needed to get out of the house.

"I think it's time for me and my baby to hit the road," he mumbled to himself, pulling himself up from the sofa. He put the beer back in the fridge and went to the room he was crashing in to grab his things. As he packed his bags, he thought about how bored he'd get having a road-trip on his own, and wondered who he could contact to take around America. It was then he realised he didn't actually have many friends. Cas was the only person who came to mind.

"Cas won't want to come on a road-trip with me..."

He shook his head and continued packing when he felt a presence behind him. He spun round and saw Castiel stood in his doorway looking confused.

"What's a road-trip?"

Dean rubbed his forehead and sighed, feeling his heart beating heavily in his chest; he was used to Cas just appearing, but every time it scared the life out him.

"Cas. Stop, just appearing! And a road-trip is just, a trip people take, they drive wherever."

"Ok. Why wouldn't I want to come?"

Dean shrugged; "I don't know."

He turned back to packing his bags, Cas stepped up to Dean and watched him.

"I'll come with you if you want."

Dean turned around and almost head-butt Cas he was stood so close; "fuck! Cas! Personal space!"

Cas nodded and took a step back; "I apologise."

"...You want to come?"

"Yes... Where are you going? I'll meet you."

Dean shook his head; "no, you don't get it. It's not about where you go, it's about actually going there."

"...I don't understand."

"The point of a road-trip is the actual journey you take..."

"...I still don't understand."

Dean sighed and grabbed Cas' shoulder, forcing him to sit down on the bed before sitting next to him; "right. You go on a road-trip to travel. To, drive somewhere and back with a friend and just, enjoy the journey. It's not about about being there, it's about getting there."

Cas nodded; "ok... I think I understand."

"Good, so no, zapping off without me."

"Ok."

Dean finished packing and hauled his bag out to the Impala, Cas following close behind.

"So what do we do on the road-trip?"

Dean shrugged; "whatever. Chat, bond, I don't know... You could learn about us humans."

"How?"

"Ask me questions, I'll answer them."

"Ok."

"Get in, I'm just going to lock the door."

Cas nodded and went and sat in the passenger seat, waiting patiently. Dean quickly checked everything was locked before jumping in to the car and starting the engine.

"You know what Cas, I'll let you pick the music."

He reached onto the backseat and grabbed his box of cassettes, putting it on Cas's lap. The angel eyed them suspiciously before picking one up.

"...Highway to Hell? Dean, this isn't appropriate."

Dean laughed nervously; "uh, yeah, we don't have to listen to AC/DC, pick something else."

Cas picked up the next cassette he saw; "Paranoid, Black Sabbath."

"No, they're not really appropriate either."

"...Why?"

"They're just not."

Cas nodded and picked up tape after tape, shaking his head at anything to do with Hell or the Devil; "do you have anything that isn't about Hell?"

"...Bon Jovi?"

"What do they sing about?"

"Girls mainly."

Cas looked down; "I don't like women."

Dean almost choked on his own spit' "wh-what?"

"They frighten and confuse me."

Dean smirked; "well yeah, they're women, Cas."

"They have a strange fixation with me."

"Well, you're strange, and cute."

"What?"

"Look, nevermind, you don't have to listen to songs about girls or Hell, that doesn't really leave much."

"What does it leave?"

"...Led Zeppelin!"

Cas looked up; "what do they sing about?"

Dean frowned; "I don't actually know, weird things. Sometimes they sing songs about sex? I don't know."

"Ok."

A smirk spread across Dean's face; "pre-marital sex, Cas! With women!"

Cas shrugged; "pre-marital sex isn't that big a deal any more."

"But women Cas!"

"...It's all right."

Dean grinned and turned his stereo on, Led Zeppelin already in. Their journey began, Dean didn't take long to start singing along to his favourite band as they left Bobby's yard and headed west. Cas sat still, his hands resting on his legs, looking forward. When they merged onto the highway, Dean turned the music down and glanced across at Cas.

"Tell me, Cas. Why don't you like women?"

"I said, they scare me."

"I know... But why?"

"They, just, I don't know."

Dean smirked; "they flirt with you? Make you uncomfortable?"

Cas nodded; "yes... I prefer men."

"Men aren't going to flirt with you, Cas."

"Why?"

"Because the men you meet aren't gay."

"...Gay?"

Dean sighed, never imagining he'd be having this conversation with Castiel; "a gay man is someone who's attracted to men... Sexually."

"Ok... Am I gay?"

Dean almost lost control of the car as he began choking again; "I uh, I don't know Cas! Are you sexually attracted to men?"

"...I'm not sexually attracted to anyone."

"Then no!"

"Ok."

Dean glanced over at Cas suspiciously as he carried on driving; he knew Cas didn't understand, but the atmosphere was now extremely awkward. Dean couldn't shake the idea of Cas being gay, especially seeing as Cas had said he preferred men - obviously not sexually, but still...

The two sat in silence for a few minutes before Cas spoke.

"Where are we going?"

Dean grinned; "wherever the road takes us, Cas."

Cas nodded, accepting that as an actual answer. Dean chuckled to himself and pulled off the highway.

"What are we doing, Dean?"

"Finding somewhere to stay for the night, and I'm hungry."

After finding a motel, Dean and Cas went to find a diner. Whilst Dean waited for his burger and fries to come, he watched Cas observe everyone in the diner with interest, clearly studying the human behaviour. Every time something would confuse him, he squinted slightly and tipped his head to the side; Dean couldn't help but smile every time he did, likening him to an adorable puppy. He was so busy smiling to himself, he didn't notice Cas look at him.

"Dean. Why do people hug?"

Dean shook his head, coming back to the real world and shrugged; "I can't really tell you... I suppose, because, they mean something to one another? I hug Sam because, he's my brother and, it's my way of showing, appreciation and love, without a total chick flick moment. And... Couples hug because, it's a display of affection? I don't know, there's lots of reasons."

"Can you give me examples?"

"Hugging because... Someone did something nice for you - you'd have to know the person well though, otherwise it's creepy. Um, finding out someone is safe, hugging someone because you love them, because... You haven't seen someone in a long time."

Cas nodded along, Dean could see him thinking diligently.

"Why do you want to know?"

"Because you humans hug an awful lot, and I don't understand."

"Well, you do now."

Cas nodded; "I do."

"Anything else? Do you understand kissing?"

"I think so."

"Go on..."

Cas looked around and cleared his throat; "you kiss someone when... You want to have sex with them."

Dean laughed, making Cas frown.

"Is that not right?"

"Yes and no. You kiss your boyfriend or girlfriend because you love them, most of the time yes, you want sex from them but it's not the only reason. BUT. You can kiss your family too."

Cas' eyes widened; "that's a sin!"

Dean chuckled; "not sexually! You kiss your granny because she makes you, you kiss your mum because, she's your mum and you love her! You kiss your dad because-"

"-Why do you kiss your family!"

"I'm explaining Cas! And you don't make out with them, it's just a small peck on the lips, or cheek, or forehead or, whatever. And you kiss your friends like that too. Girls usually kiss their friends on the cheek as a sort of greeting. Gay guys do the same. Girls can kiss girls but boys can't kiss boys."

"...Why?"

"It's just weird! Unless they're family."

"Ok... So I can't kiss you, but you can kiss Sam?"

Dean cringed slightly; "on the forehead or something."

Cas nodded; "I understand."

Dean nodded and grinned when the waitress came over with his meal. She looked over at Cas.

"You sure you don't want something, hun?"

Cas just eyed her suspiciously, not understanding it was him she was talking to.

"Cas! She's asking if you want food?"

"Oh, no. I do not need food to sustain me."

The waitress looked at him weirdly; "all right?"

"What he means is, he already ate," Dean explained. The waitress nodded and looked back to Dean.

"You want any coffee?"

"...Yeah, Cas, want some coffee?"

"Coffee?"

Dean rolled his eyes; "yeah, two coffees."

The waitress nodded and walked away. Cas leant over to Dean.

"Why did she call me hun? That's not my name."

Dean laughed and took a huge bite out of his burger before answering; "it's just a term of endearment."

"But she doesn't know me, how can I endear her?"

Dean rolled his eyes and took another bite of his burger, wishing he hadn't promised to answer of all Cas' questions. Cas waited patiently for his response.

"People just do it. You don't have to know them. I call girls baby, and, gorgeous if they're good looking..."

"This is very complex."

"Yes, maybe we should go over this another time."

Cas nodded and sat back in his seat, eyeing the coffee suspiciously when the waitress brought it over. Dean managed to finish his burger at expert speed before pulling his coffee towards him, grabbing some sachets of sugar from the bowl already on the table.

"What are you doing?" Cas asked, watching Dean intently.

"...Putting sugar in my coffee."

"Why?"

"...Because I have sugar in my coffee!"

"Ok."

Dean stirred his coffee, watching Cas stare at his cup; "are you going to drink yours?"

The angel paused before lifting the cup to his lips, he took a small sip before pulling a face of disgust; "it's so bitter!"

Dean laughed and pushed the bowl towards him; "put in some creamer, and sugar then."

"What does that do?"

"The creamer, dampens the bitterness, and sugar adds sweetness."

"How many should I put in?"

"One creamer, try it, one sugar, try it, then keep adding until it's fine."

Cas nodded and began altering his coffee. Dean smiled and drank some of his coffee before finishing his fries. Despite Cas' obvious lack of human skills, and general awkwardness, he was fun to have around. His lack of understanding of anything was funny, his innocence was adorable, and the fact he never argued with Dean was perfect. He'd sit quietly and say nothing until a question popped into his head. It was frustrating answering his questions, mainly because things came naturally to Dean, and he'd never thought about the reasoning, so to explain things like hugging was difficult. However, he knew Cas was just curious, like a child. A very powerful and very strong child.
