They were celebrating, kind of. It was new years eve and by celebrating Sam, Dean, and Cas were sitting in the bunker drinking beer watching the ball drop on the T.V. "10...9...8..." By five the three very drunken men were counting along. They cheered with the crowd when they reached one.
Cas didn't cheer though, his eyes were on Dean.
"What?" Dean asked.
Cas leaned forward and lightly pressed his lips against the hunters pulling away quickly. He smiled happily. Sam burst out laughing at the dumbstruck look on Dean's face.
His laughter died away when he noticed the Angel had moved in front of him. Eyes scanned over his face quickly then Cas smiled slightly and he was treated to the same soft press of lips. When Cas started to pull away he tangled a hand in his shirt and pulled him back closer. Tongue slipping into his mouth tasting the alcohol and the candy like sweetness he was almost positiive was all Cas. He let him go feeling a little unsteady on his feet.
"What the hell was that?" Dean asked not sure which part he was wondering about.
"It's customary to kiss at midnight." Cas said softly looking at dean like he was the one who was clueless.
"Yeah but that's a couple thing not a friend thing." Dean said radiating annoyance in every word.
"My mistake." Cas whispered looking down uncomfortably.
"It's fine Cas." Sam whispered rubbing a small comforting circle against the small of his back. "Dean's just jealous I got the better kiss."
"How drunk are you?" Dean asked eyes going to the beer bottles littering the table.
"I'm fine." Sam said smiling "Very actually. Doesn't mean I haven't noticed." He shoved Cas toward Dean not taking his hand off his back. "You should really try that again." Sam said looking at Dean. Dean's hands landed on the angel's waist pulling him in closer before he thought about it.
"Happy New Years Cas." He whispered. His warm breath brushing over the angel's parted lips. For an instant he wasn't sure if he wanted to pull him closer or push him away he'd been fighting against this moment for so long that now that it was here he knew he hadn't fought hard enough. He'd seen what Cas could become under Dean's influence. But they changed it. That version of Cas had been prevented.
"Does this mean we're a couple?" Cas asked just before Dean closed the distance between them.
The words were swallowed in the kiss, a long slow seduction that broke when Sam cleared his throat. "You two need some privacy?"
"Sam." Cas whispered his name and in an instant he was pulling the other hunter closer. "I want both of you."
"Cas we can't do that." Dean whispered, not sure how to explain relationship dynamics to an Angel that clearly didn't have boundaries.
"Throughout all of your human history siblings have shared spouses." Cas looked between them "It is both normal, and condoned by heaven...well before heaven went bat shit insane." He took a breath "I want to be with both of you."
"Not at the same time." Dean said as if that were the only rule he was laying down.
Cas considered and nodded "I think you would really enjoy it but I understand your inhibitions. The taboo is quite common." He looked at Sam "Do you have conditions to add?"
"I'm good." Sam whispered still in awe, "This is weird, but we share everything else, why not an Angel to?"
"Okay." Cas said kissing him much slower nipping at his lips with his teeth. "I think this year is getting off to a very promising start."
"Jesus, I need a drink" Dean muttered. Though he had to agree.
