Dean had just gotten back from a pie run, and Sam was out for a drink alone. Cas was waiting for him when he got back. They were doing research on where Abaddon could be, since Crowley was MIA. Cas couldn't take it anymore. The silence was a perfect opportunity to confront Dean.
"This mark is doing something to you Dean, you've been different," Castiel observed. He saw something in Dean that he had never seen in him before.
"I'm fine," Dean replied.
"You can tell me anything, and you know that," Cas pleaded. He just desperately wanted to help heal Dean. Even if it took the rest of his grace, he would heal Dean if he had to.
"Fine. There is something wrong."
"What?!" Cas was dying to find out.
"It's the blade. When I'm around it, I just feel this high, like I need to kill something, this itch…. But there's something else too; it's like the power is getting to me."
"What is this something else?" questioned Cas.
"I just want you." Dean took a step towards Cas and put his hand on his cheek.
They both quietly looked down at their feet. Cas couldn't take it anymore either.
He grabbed Dean and their lips met.
The Mark tingled with a sensation of pleasure on Dean's arm.
He finally felt complete for the first time in forever; like he had everything he needed right in front of him.
The feel of each other's bodies was perfect. Cas felt wonderfully unholy. He didn't have his wings anyway and his grace was running out.
Dean started stripping Cas of the trench coat, Cas began unbuttoning Dean's shirt.
He had one hand on Dean's chest, one on the back of this head.
Soon, they ran to Dean's room, never leaving each other's lips.
They crashed on the bed, Cas on top, tangled in each other. Cas lifted his head for Dean to kiss every inch of his neck.
"Maybe this mark isn't so bad," Cas whispered in Dean's ear breathlessly.
They removed each others belts, and soon there was nothing left but each other.
They giggled and rolled over together. Now Dean was on top. He stopped for a second and just said,
"Cas, I love you," and proceeded with kissing Cas endlessly. It was a perfect start to a perfect night.
