A few months later, after Dean had stopped calling for Castiel and Cas had once again started to look down on the Winchesters, Dean went on a solo hunt for a werewolf. Castiel watched over him, as he always did, because he had promised to do so. He expected the Winchester to find some other girl to pass his spare time with, but this time that wasn't what happened.
Dean called Cas down to earth one night. He sounded desperate, and so Castiel flew down to see him, appearing in his old human form at the end of the hunter's motel bed. 'Hello Dean.'
'Cas,' Dean said, surprised, 'you came.'
'You sounded like you needed me.'
'I always need you, Cas,' Dean said. 'You're my best friend.' He patted the space next to him on the bed.
Castiel approached him warily, mind fixed on what had happened last time Dean had made that motion. 'Why did you call me?'
'I wanted to talk to you,' Dean explained lowly. 'I'm sorry about what happened, I… I didn't mean to hurt you. I'm sorry that I said it should never have happened, because that was a lie. I'm really glad it did happen, actually, I was just confused and conflicted but Cas, I want…' he sighed. 'I want you.'
Dean leaned in to kiss him but Cas pulled away. 'I do not understand.'
The Winchester sighed and looked down, composing himself before looking back up, meeting Cas' electric blue eyes with his own green ones. 'I lied, and I'm sorry. I'm not ashamed of you or anything, and I'm sorry if it seemed that way.'
Castiel nodded slowly, and shifted closer. Dean placed his hand on the angel's cheek, and when Cas didn't pull back from the touch, Dean took it as a sign of consent and slowly leaned in to kiss Castiel. Cas let him do so, revelling in the feeling of Dean's lips on his again after so long.
They continued kissing as Dean slowly pulled Castiel closer by the edges of his trench coat. Cas let himself be moved and adjusted, and was so caught up in the taste of Dean, his Dean, that he hadn't realised he was lying on the centre of the bed until Dean began to unbutton his shirt.
'Dean, what are you doing?' Castiel asked uncertainly. He had seen Dean do this before, with girls, but he didn't understand why the Winchester would be doing it now, would want to engage in such acts with him.
'I told you I want you,' Dean said. He pulled back slightly. 'You don't mind, do you?'
Castiel looked up at him; bright green eyes shining in the barely lit motel room, brown-blonde hair meticulously styled, full pink lips wet from kissing. Of course he wanted it. He shook his head. 'I want you too, Dean.' And he meant it.
Dean captured the angel's lips in his own again and continued undressing, first himself and then Cas. Cas let Dean take the lead, shifting whenever it was needed so that their cloths could be removed.
The Winchester never stopped kissing him, lips all over the angel's pale skin. 'Cas,' he whispered, and a shiver ran down Castiel's spine because never before had his name been said like that, as though it was anything anyone had ever known. The way Dean said it, with such awe and reverence made him feel warm and his skin felt as though it had been passed through by a thousand tiny warm flares of his angelical grace.
