There was an involunatry moan hummed against the demon's neck as Crowley's hand tangled in his hair. That was just something that would always get his attention. And as Kol listened to all the reasons the other found his vampire so bloody brilliant, he let his 'true' face shine through as he bit into Crowley's neck. He just couldn't resist it, he just tasted so damn good, and he knew the demon never minded it. Just one of those things they both always got a little something out of.
He eventually found his way back to reclaim the demon's lips, traces of blood still lingering on his lips as he bit playfully at Crowley's lower lip. "That's a lot of reasons," he mumbled, smirking slightly.
