Sam and Dean both knew that you had a major MEGA crush on Cas and that is saying the least. Whenever the man, wait, angle. Yah... Whenever he popped up or visited you would either run away or hide. Either way he innocently thought that you 'needed assistance'.
Anyways, currently you were hiding under the bed in a random motel room with Cas staring at your squirming feet. "(Y/N)? What are you doing?" He questioned your sudden weirdness, and you really didn't blame him for doing so. "Oh, I'm fiiiiiine! Just, um, go talk to Dean about the new c-case for now alright?" You panicked an struggled even more from under the small, dark crevice.
You were stuck at the hips and un-knowingly giving said angle a great view of your, as he would say, 'bottom'. He couldn't help but take notice and blush a bit. You on the other hand decided that you were stuck. Trying harder and harder to get out was pointless. "Are you sure you don't need assistance (Y/N)"?
You stoped. Gave up, and replied with a yes. He started to grab your ankles and pull. Even this made you blush. Ugh, what was when get with you?! Then you realized that you really had a reason to turn red. As Cas pulled you along your shirt dragged on the carpet. When you finally got out Castiel got a clear view of your bra. You pulled down your shirt immediately after getting up but it was too late...
Que the redness, moment of shock, and running. Lots of running. But before you got to the last part, Castiel graves your wrist and pulled you into his arms. Before you got another chance to hide or squirm away he kissed you on the lips.
And now for a moment of (Y/N)'s thoughts~
OMG IS THIS HAPPENING?! HOW!? WHY?! CHESSUS CRUST! HOLY BALLS OF BATMAN!!!
Now returning to your scheduled fanfiction~
You were still in Cas's arms but after you two broke apart for air you had gotten as red as a fire truck full of strawberries in an apple orchard at sunset. "Why am I such an awkward tomato?" You said muffled with your hands on your, quite warm, face.
"It doesn't matter why, as long as your my awkward tomato. Only mine."
And with perfect timing Sam and Dean walked in. "Ah, Cas? Do you need a sec buddy or you gonna keep with the whole 'pure' thing, cuz that could change here." Dean stated with his signature smirk.
"I think I'll take that second." Castiel smiled and looked towards you again with a smile. With that he booped you away and let's just say you guys had a second... Or two... Or a lot!
