My first Supernatural-fanfic. I just thought this part of the episode (5x03) should have a different ending. Slightly Dean/Cas. (This may have a follow up, not sure yet).

'Last night on Earth, so what are your plans?' There was a silence while Dean waited for Castiel to answer.

'I thought I'd just sit here quietly,' Castiel replied with a straight face. He had never really thought about it. He had no-one to love and nothing fun to do because well, angels don't have fun, they follow orders.

Dean frowned as if he hadn't heard what Castiel had said. Sit there? Was he serious? At first Dean thought he was joking, but when Castiels facial expression didn't change, Dean realized he was being dead serious.

'Dude, come on, anything?' He stepped closer to Castiel.

'Booze, women?' He stopped moving when Castiel looked up at him, still with the same expression on his face, but when he mentioned the "women", Castiel seemed to get uneasy. He looked away and didn't reply. After a few seconds it hit Dean.

'You have been with women before..right? Or an angel at least.'

Castiel nervously wiped some sweat from his neck and did all he could not to look at Dean. All these questions made him think. No, he never even thought of doing something "fun".

Dean was stunned. He knew what this meant. But never..?

'You mean to tell me you've never been up there doing a little cloud seating?'

Uncomfortable and embarrassed, Castiel stared vague into the distance.

'I never had the occasion okay?' he answered with a straight face. He could not show Dean he was embarrassed. If only he could get his heart stop pounding so damn hard.

Dean was stunned. No, even more than stunned. He could not believe a guy, angel or not, "never had the occasion" to have some fun. Even if angels were dicks, at least one had to be attractive. And on Earth were plenty of sexy, hot girls. But Castiel, a virgin? That thought was just stunning. And imaging him dying a virgin was even worse than stunning, it was close to scary and frightening! Something had to be done.

'Alright,' Dean said, while he walked over to the table to get his coat.

'Let me tell you something. There are two things that I know for certain. One: Bert and Ernie are gay. Two: you are not gonna die a virgin. Not on my watch. Let's go.' He had just put his coat on and walked towards the door when Castiel stopped him. There was a moment of silence, as usual when Castiel had something to say.

'What?' Dean asked impatiently.

'I eh.. Let's say.. It's..' Castiel mumbled. Dean frowned. What was wrong with this guy?

'Speak up or let's go,' he said. Castiel swallowed hard and his eyes drifted off to the floor.

'I don't really know.. how to..kiss,' he whispered. There was another long, awkward silence. While Dean was still frowning, not understanding the man in front of him, Castiel was slowly turning red on his cheeks. He felt his heart race in his chest and his hands got sweaty. What was this feeling?

'So you're a crappy angel, you never have fun, you're going to die a virgin AND you don't know how to kiss? What's wrong with you man?' Dean sighed and raised his arms like this was a lost cause. Castiel kept looking to the floor, his heart pounding so hard he could hear it in his ears.

'Hey it's okay, they won't mind..'

'You don't understand. I won't satisfy their needs. I don't have feelings, I'm an angel,' Castiel interrupted him. Dean smirked.

'What's so funny?'

'For a guy who does not have feelings you've got a pretty red face,' Dean chuckled. Castiel put both hands on his cheeks. They did indeed feel very warm.

'Dean, I just don't know-' Castiels sentence was cut off by Dean, who stepped forwards, took Castiels head in his hands and pressed his own lips tender on Castiels. Dean had his eyes closed but Castiel had his wide open. His heart seemed to stop when he felt something warm and wet slip between his lips and curled softly around his tongue. It was weird to feel Deans tongue touching his, but at the same time it gave a warm feeling that spread through his whole body. The kiss seemed to last forever, but all of a sudden it was over. Dean pulled his head back and stared for a long, silent moment into his eyes. Castiel saw a blush on his cheeks, but it was gone quickly and he wondered if he had imagined it.

'So..that's a kiss,' Dean broke the awkward silence. Castiel nodded and cleared his throat.

'So this is how it feels like when you kiss a girl?' he asked, touching his own lips. This was something he'd never forget.

Dean just smiled.

'Let's go okay?' He turned around with his back to Castiel and walked towards his car.

'Oh, it's nothing like this,' he whispered to himself, smiling, with one hand on his racing heart.

thanks for reading :) please tell me if it's worth a follow up!
