"Where have you two been?" Your older brother Dean inquired with a teasing grin.
"You already know, Dean. Why are you asking?" Cas interrupted your halfhearted glare with a matter of fact response. "In Y/N's room, figuring out a case."
"Yeah, a case. Of course." Dean jerked his head to the side, still clearly amused. "But you know I got up in the middle of the night and your light was on. Betcha didn't get any sleep last night, did ya Y/N?"
Your face burned by your glaring to him. You could feel your heart radiating from your cheeks. The best glare you could muster had no effect on Dean, but you stick with it anyways.
"No, she didn't."
Cas replies for you when you remained silent. He reached for the coffee pot and poured himself and you dark liquid in a mug before passing it to you. He smiles contentedly down at you watching as you held it in between your hands and inhaling the steam.
"We were up all last night. Not a problem for me, as I don't require sleep, but I was surprised at Y/N's stamina."
Dean ducked his head down, hiding his face, but his shaking shoulders gave him away.
"This morning, however it does seem like it has caught up to her. I hope you didn't push yourself too far, Y/N." He finished sincerely.
Dean snorted unable to hold back the laughter. Your other brother Sam shook his head to dismiss the childish behavior, but a smile ghosted over his lips. Dean cleared his throat.
"You know, Y/N." He stopped for a second then continued. "You could take it slow at first-" He began his mock explanation only to be interrupted by a kitchen towel to his face.
"Shut up, we were researching and you know it, Dean." You spat.
Cas' eyes narrowed. "I don't understand. Why are you laughing?" Cas looked at you in confusion.
You huffed in embarrassment, eyes moving over to your brothers faces. You turned back to Cas, grabbing his sleeve, and stood on your toes to whisper over his shoulder, into his ear. He nodded at your explanation finally understanding. He met Deans eyes eventually.
"Of course we did not have intercourse all night." He reprimanded in a matter-of-fact voice. "For one, that seems like it would be extremely uncomfortable for humans when two hours-"
Dean sputtered. Sam glanced back at you partially concerned, partially impressed.
"-suffices just fine. And more than that and I'm afraid I'd hurt Y/N. Secondly, we'd never "do it" when you guys are in the bunker." Cas looped his arm around your shoulders completely unaware of your red face. "Y/N can get a little loud." You faced towards Cas with aggression.
Dean stood up. "I don't know whether to be disgusted or proud of you, Cas." His sour expression bloomed into a cheesy grin as he walked towards you. He clapped a hand on Cas' shoulder, sending a wink your way. "But if you ever hurt her, Cas-" Dean explained, "I'll have to kill you." Dean continues.
Cas looks at you then looks back at Dean.
"But hey congrats man, you're a beautiful filthy human/angel addressing your animalistic desires now. And Y/n..." He shook his head. "You be gentle, I don't want it on my conscious that my sister killed an angel/human."
Dean took a long sip of his coffee barely concealing a smirk. You had to be honest with yourself. You thought Sam and Dean would not want you to have romantic relations with an human/angel. He is human now, because his grace got taken, but you worried how Cas would react when Cas is an angel again.
As Dean walked into the kitchen with his robe tie dragging on the floor, Sam jerkily closed his laptop before scooping it up, offering a hesitant thin lined smile to you as he stood.
"Congrats guys, really." He muttered, then ducked his chin to his chest and follows Dean into the kitchen.
"Sams rather supportive, isn't he?" Cas smiles contentedly.
You were beginning to feel a little light headed with the amount of blood pounding in your head.
"Y/N, you're red." Cas points out.
You let out a frustrating groan. "I'm embarrassed." You explained.
"Why?"
Not wanting to worry Cas, you finished your explanation. "I can't help it, Dean was teasing us." You rolled your eyes, looking at the kitchen.
Cas considered your words for a moment, then leaned closer to you in that stiff endearing way he always did to reinforce his point. "I hope he continues, you look cute when you're red."
He shoots up, pecking a kiss on your head and heading into the kitchen with your brothers. You roll your eyes in annoyance and took out a spell book and scanned it.
