Dean knocked on Castiel's door precisely three times.
"Go away, Meg." Castiel snarled. "Um, actually, it's Dean. If this is a bad time, I can come back-" Castiel interrupted Dean, "Never a bad time. I'll be right there." He realized he probably sounded way too enthusiastic, but he didn't care. He rolled out of bed, quickly put on his pants, and opened up the door to let Dean in. Dean doesn't hate me, he told himself, he doesn't hate me. Inhaling deeply, he motioned for Dean to come inside.
"What is it?" he asked, shutting the door. "I barely remember what happened at that party a few days back. I remember that you were there and we got drunk….and I woke up with you in my bedroom." Castiel's face fell. He hates me. "We didn't have sex, if that what you're worried about. At least, I don't think so." Castiel imitated a sarcastic tone as best as he could.
"This is going to sound pretty weird," Dean prefaced, "but it wasn't, uh, I mean, I didn't… Fuck," he sighed, "can I just kiss you now?" Castiel stared at him blankly. Did Dean Winchester just ask to kiss me? Am I going crazy? He thought. Castiel mouthed "Yes." (when he really meant "Yes. Yes. Fuck, yes, I've wanted you for so long.")
It started out with Dean cradling Cas' face in his hands, slowly bringing their lips closer and closer until they finally touch, Dean's soft lips gliding gently over Castiel's own. Then, it grew hungrier. Dean pinned him up against the wall, Castiel's heart racing as Dean kissed him hard, as he bit down on Castiel's lower lip. Castiel let out a soft moan as Dean kissed his collarbones and sucked on his neck.
The sound of the door creaking open stopped them, and Meg walked in with a growing smile on her face. "Sorry to interrupt," she said as she realized what was happening. "I'll be going now."
Dean rolled his eyes and resumed the kiss.
