Castiel stood alone in the bunker. His wings ached from being trapped for so long. Cas decided to hide them from Sam and Dean a long time ago because he thought they made him different. He wanted to be just like his friends.
Cas decided, since Sam and Dean were on a hunt, that he would stretch his wings for a while. He sat on the couch with his wings fully extended. He forgot to take off his shirt, so now there were massive holes where his dark wings sliced through. Castiel would need to buy a new shirt.
Suddenly, the door opened. Dean walked inside and froze in his tracks. Cas tried to speak, but couldn't find any words.
"They're-" Dean started.
"I'm so sorry, Dean. I'll put them back. I don't ever let anyone see them. They make me feel different," Castiel confessed.
"You didn't let me finish," Dean started. "They're beautiful, Cas." Dean walked toward the angel. He stroked the wing closest to him and Cas moaned involuntarily.
"You like that?" Dean laughed.
"Dean, they're very sensitive," Cas said.
Even though Castiel somewhat warned him, Dean continued running his fingers through the black feathers.
Castiel couldn't take it anymore. He turned, facing Dean and crashed his lips against his friend's. He felt a pang of regret but that only lasted a minute because Dean actually kissed back. Their lips moved, synchronized, until Cas finally pulled away.
"I guess you weren't kidding," Dean chuckled, sarcastically. "Your wings really are sensitive."
Dean kissed Castiel once more before moving back to the wings. He ran the feathers through his fingers, Cas letting out a small moan each time. Dean smirked. He kissed down each of his angel's wings until Cas turned around and pushed Dean into a wall, pressing their lips together.
"Wait, Dean. Where's Sam?"
Dean's eyes widened as he turned his head to see a smiling moose standing by the door.
"H-how long have you been here?"
"Long enough, Dean," Sam smiled.
"Son of a bitch."
"Don't worry, Deanie Bear. I've known this was going to happen for a long time. Listen, I've got, um, somewhere I have to be. I'm just gonna leave you two in the bunker...alone...for the whole night," Sam said, wiggling his eyebrows up and down.
