"Cas. Hey, Castiel." Sam knocked on his friend's door a few days later. Their skin was back to normal, and the excitement of the "prank wars" had died down. He'd let Dean think that maybe he wasn't going to do anything, so that his brother would find this plan totally unexpected. The former angel opened his door slowly, smiling softly at the hunter.
"Hello, Sam. What do you want?"
Sam pushed the door open further, stepping in quickly and closing the door behind him as quietly as he could manage, as if the light creak of the hinges would get his brother's attention. "Dean's in his room, looking at porn or something."
Castiel tilted his head, a minor look of disgust evident on his face. "Is this of any import?"
Sighing, Sam gave Castiel a sympathetic look. "This may be... awkward for you, but I was hoping you could do something for me."
Castiel silently awaited Sam's request.
"Will you kiss Dean for me?" Sam grimaced, holding up a hand. "I mean, not for me, but… I'm asking you to kiss him."
Castiel's face scrunched into a baffled frown. "I don't understand... Why do you want me to kiss your brother?"
Sam smirked, folding his arms across his chest. "Because it'd be hilarious. And it's payback."
Cas began to nod slowly, looking at the floor in consideration. "For what he did to us on Tuesday?"
"Yeah."
A look of hesitance appeared on the former angel's face. "I... I don't think I should-"
"Look, Cas, it'll be funny. Trust me. He'll never see it coming. He'll flip out. It's the best prank," Sam explained.
Castiel nodded silently, then turned to the door and left the room promptly.
Sam smiled to himself. This is going to be awesome, he thought, barely suppressing a laugh.
"Dean?"
Dean looked up from a classic issue of Busty Asian Beauties when he heard Castiel's voice. He cleared his throat, shifting where he sat on his bed. "Come in, Cas."
Castiel obeyed, his eyes darting around the room as he stepped in nervously, closing the door behind him.
"What's up, Cas?"
The shorter man avoided looking at Dean as he came closer to his friend, sitting beside him quietly.
"...Cas?"
Castiel finally met Dean's slightly unnerved green gaze as he began to slowly lean closer to the hunter. "I have to do this...," he muttered.
Before Dean could question, Castiel quickly covered the hunter's mouth with his own.
Not even 3 seconds passed by before Dean managed to push his friend away. Castiel looked down awkwardly, and failed to see his flustered friend's fist quickly approaching his face.
When Cas finally stood from where he'd fallen to the hard, cold floor, all Dean could do was shout, "What the hell was that?!"
Cas couldn't meet his friend's glare. "...I believe it was supposed to be a prank."
Dean frowned, wiping his mouth with the back of his hand.
"It was Sam's idea. He said it would be funny."
"Oh." Sam was just using Cas to get back at him. Suddenly, Dean realized he'd just decked his poor, confused friend. "Sorry, Cas," he muttered as he got on his knees beside the shorter man.
"I... understand, Dean. I'm sorry. I shouldn't have listened to your brother."
Dean smirked. "We'll get him back," he decided as he lifted the fallen angel by the arm and walked him to the door.
"I don't want to do this 'pranking' anymore, Dean. It's... unpleasant."
Dean frowned at the black eye his friend was quickly developing. "Yeah. Sorry. But this one will be different, okay?"
Castiel looked skeptically at the man who was gripping his arm, probably giving him another bruise, though this one was unintentional. "How will it be different?"
Dean smirked bigger than ever. "What if we let Sam think that, instead of getting mad, I liked what you did?"
"I don't understand."
Rolling his eyes, Dean explained, "We'll let him think he made us gay, Cas. We'll act like a gay couple and do gay things and he'll have to watch and think it's because of what he made you do. We'll be so overly affectionate, he'll go nuts."
Castiel seemed to be considering this idea, nodding as he met Dean's mischievous gaze.
"What do you say? Will you be my boyfriend?" Dean batted his eyelashes in a way that was so ridiculous it actually made Castiel laugh.
"Okay. For how long?"
Dean shrugged. "I dunno," he said as he opened the door, patting Cas on the back. "Just follow my lead, okay?"
"Dean. He can see that you punched me." Cas squinted his right eye, drawing attention to the dark purple mark Dean had put there.
"Right." Dean thought for a moment, then grinned. "Don't worry, I have an idea."
