Imagine being Castiel's little sister and having him find out about your relationship with Crowley.
This is based around the time when Cas still tried to find God.
"Shhh!" I laughed quietly as Crowley wrapped his arms around my waist, helping me stand up.
"You're going to wake up Castiel if you keep making noise." He whispered next to my ear. I turned around in his arms so i faced him.
"Cassy isn't even here." I wrapped my arms around his neck and pressed my lips to him.
"You taste like whiskey." He smiled and I giggled.
"(Y/n)?" I quickly turned around and pushed Crowley's arms off of me.
"Cas is going to flip." He stated
"Dean please don't tell him." I staggered towards him.
"Are you okay?" He asked and I nodded as I fell forward into his chest. "What the hell did you do to her?" Dean asked Crowley angrily
"Calm down squirrel. I did nothing wrong. She was drowning her sorrows in a bottle of cheap liquor and I brought home." Crowley stated with his hands out in front of him. "There was no harm brought to her."
"If there's a single scratch on her I will hurt you." A new voice joined into the conversation
"Castiel." I stood straight with my arms by my side. "Brother, I am fine." I squeaked as he walked towards me.
"Did he do this to you? Did he force you to drink?" Castiel placed his hands on my shoulders. I shook my head, which in itself was a horrible idea. My hand flew to my mouth before I took off running towards the nearest trash can. I quickly felt a hand on my back and one holding my hair back.
"You'll be alright, darling." Crowley spoke from behind me.
"Step away from her Crowley." Castiel stated firmly.
"Cas. They're.." Dean paused "I think they're dating." I slowly stood up and turned back around to face my brother and Dean as I wiped my sleeve over my mouth.
"(Y/n). Tell me that isn't true." Castiel insisted desperately. I stood close to Crowley and bowed my head guilty. "(Y/n)." Castiel sighed "How could you? Father will not be happy." He stated
"Father? Really Castiel? Bringing up God, he's been MIA for centuries!" I said "I don't care if he's unhappy, all that should matter is that I'm happy, and if that doesn't matter may he smite me down where I stand." I closed my eyes and clenched my fists expecting to be killed right then and there, but I wasn't.
"This isn't right." Castiel stated
"Neither is killing other angels but you don't seem to be bothered by that." I huffed as I grabbed a hold of Crowley's hand.
