A/N: Seeing as a posted the other one... Based off a post on Tumblr and likely been done before, but does it look like I care?
Dean was in the middle of drinking his beer when Castiel appeared next to him in a rustle of feathers.
The hunter jumped, almost losing the bottle to the carpet below, but kept the cool bottle in hand.
"Hey, Cas." he greeted a little stiffly.
"Hello Dean." The angel returned. "May I borrow your hand?" he asked suddenly.
Dean took another swig of his beer, looking at Castiel down the neck as he tipped it up. He swallowed. "Do I get it back?" he asked.
"I have no intention of keeping your hand." The angel confirmed with a bemuddled expression.
Shrugging, the hunter offered his free hand to Castiel as he took another swig of his beer. The angel stared at said hand for a moment, before taking it in both of his.
Out of nowhere, a ring was slipped into Dean's fourth finger. He pulled away, startled. "What the hell, dude?!" he exclaimed, looking up at Castiel.
The angel just nodded contently and disappeared in a flutter of feathers.
"It won't come off!" Dean exclaimed from the kitchen.
Sam and Bobby exchanged glances. "Tried olive oil?" the younger Winchester called to his older brother.
"Yes!" he hissed. There was silence for a few moments, but then, "For fuck's sake! Cas!"
Dean clasped his hands together as he leaned back into Bobby's dining room chair, the cool metal of the ring pressing against his opposite finger. He growled in annoyance, but closed his eyes and began to pray.
"I pray that the holy Castiel get his feathery fucking ass down here before I come up there and get it myself." he said.
He opened his eyes and looked around the small kitchen, but there was a lack of feathery ass in a tan trenchcoat. He grumbled to himself and tried again.
"I pray that the holy Castiel get his fucking feathery ass down here now... please?"
There was a satisfying yet aggravating rustle of feathers from behind Dean, and the hunter spun around to see the angel standing there, looking as Castiel-y as ever.
"Hello Dean." he greeted simply. "You require my assistance on a job?" he questioned immediately after.
Dean raised his brow, before letting out a long breath. He held up his imprisoned hand for the angel to see, putting on his best not-amused face. Castiel frowned.
"You don't like it?" he inquired, tilting his head.
"Was I meant to?" Dean returned.
"But the song... it..." Castiel trailed off, knitting his eyebrows together. "It stated that if like something, I must put a ring on it." he voiced his analogy.
Sam walked into the kitchen to get himself another beer from the fridge, but was faced with a problem.
Castiel appeared to have pushed Dean against said refrigerator, his lips pressed firmly onto his victim. Victim was in the middle of removing his shirt, and Castiel's trenchcoat and tie were already discarded on the tiled kitchen floor.
Sam left the room, deciding he would be fine without a beer for now.
He began to make for Bobby's front door as he heard the unmistakable sound of a belt buckle hitting a tiled floor. He heard a husky, "And I learned that from the pizza man too." and that was when he broke into a run.
