Wings Of Onyx (castiel x reader)

An Old Friend

As you were running, you realised something. Reaching into your hoodie pocket, your hand closed around the wrapped cheeseburger you had bought from Mcdonalds the day before when you were with Crowley. Now slightly squished, it was meant to be a peace offering for Castiel under your previous assumption that he wouldn't have been so forgiving. That was a problem for another time. Once you made it to the library you looked around frantically. Suddenly you felt a pair of hands around your waist. Expecting Cas, you turned around rather than pull away, and found yourself very nearly nose to nose with Mason, the very one who had looked after you all these years and sent you to the Winchesters in the first place. Your best friend. You then remembered what Crowley had said and pulled away.

"What do you want?" You said quietly.

"What do I... Hello? I'm your best friend! I thought I'd drop in for a surprise visit! Am I not allowed to see my favorite person? He gave Mason's signature lopsided smirk. This thing had his mannerisms down pat. He stepped toward you again, opening his arms for a hug. You reverse-mirrored his action and stepped back again.

"Uh... look. Can you just wait here for two seconds?" You turned the corner of a particularly large bookshelf and grabbed a vial of holy water from a table piled up with relics and hunting tools. Returning to where he stood, you eyed him up and down.

"Holy water?" He laughed. "Well, I suppose you can't be too careful. Go ahead then." He smiled and waited patiently. You reached out and took his hand, squeezing a bit of holy water onto the back of it. You watched in decreasing suspicion as it rolled off his skin without the familiar sizzle that was supposed to accompany the contact of devil skin with blessed water.

"But... Crowley said... I- I'm sorry. He said you were a demon." You shook your head. Mason smiled gently.

"Crowley... isn't he a demon himself? Do you really trust him to tell you the truth?" You shook your head. "I guess not..."

Come on, Y/N, you thought to yourself. I mean, you just met the guy yesterday. And you may not be too well-versed in the world of demons, but of course anyone with a title like "King of Hell" couldn't be trusted.

"Anyway, I'm here to pick you up to go on a quick hunting trip with me, if you're down. I know you like to work alone but I think we make a pretty decent team."

"I don't know about right now, Mason..." In all honesy the only thing you wanted on your schedule right now was to spend more time with Cas. Plus, you had Gabriel to deal with. You wondered how Dean was handling that situation.

"Come on, Y/N," he pushed. He smirked then. "It's a vampire nest. Your favorite." He looked at you with an eyebrow raised. He knew you too well. Castiel appeared beside you then. You wondered what had been taking him so long.

"Y/N isn't going anywhere with you." Mason looked confused and taken aback. He glanced over at you for backup. You cleared your throat.

"It's fine, Cas. Crowley was wrong. He's not a demon." As if on cue, Crowley appeared next to Mason, squinting at him with his hands clasped behind his back.

"That's funny. I could have sworn-" he turned away and muttered something to himself. Mason maintained a pretty convincing look of innocence and confusion. He was a terrible liar, so as far as you were concerned, he was being genuine.

"We're uh... we're gonna go on a hunting trip. We'll probably be gone for the weekend."

Now it was Castiel's turn to look confused. "But-"

"Cas. This is Mason. The one who sent me here in the first place. For the rugaru case?"

He nodded in understanding and changed his face to feign indifference, though you could tell he was uncomfortable with this sudden declaration that you would be gone for a weekend with someone the King of Hell had somehow mistaken for a demon. The whole situation was highly suspect, but Cas would have been able to tell if it was a demon, right?. And seeing the vial of holy water in your fist, he presumed you had already tested your own suspicions and were perfectly capable of handling yourself on this trip. That didn't mean he had to like it, though.

You later brought Mason upstairs to your room to sit and talk about what you had both been up to since you last saw each other (though you conveniently left out minor details about Cas and Gabriel. What! It never came up!), and then showed him to a spare room Sam had said he could use for the night. After all, it was only thursday night. You still had a full night's sleep to get before your trip. You walked into your room and closed the door with the intent of heading straight to bed. You already had a pair of sleep shorts on and a loose tshirt and went to your dresser to get your clothing ready for tomorrow. You saw a glimmer of something in the mirror then and your breathing stopped. You leaned forward and placed your palms on the counter then, dropping your head down.

"Cas, you gotta stop doing-"

"I don't trust him."

Once you recovered from him starling you, you spun around.

"He's my best friend." Your only friend for the longest time, really. The Winchesters barely even knew you, though they acted like family already.

Castiel scoffed, but didn't say any more. He wasn't sure what more he could say. He didn't sense that Mason was lying to any of you, but something felt off. Plus, the way Mason looked at you so fondly, as though you knew things about each other from years of bonding that he wasn't in on? He disliked that a lot-

"Wait a minute..." you started, cutting off his train of thought. Are you... jealous? Of him?"

Castiel spluttered. "No, I just- look, forget it!" He turned away from you and started pacing. What was worse, he didn't even have to look up at you to know you had an absolute shit-eating grin on your face.

"I think you areee-" you sang, before he cut you off with a quick "shut up!" You laughed at him and walked over to him, giving him a light hug from behind. "Someone's crabby. Is it nap-time?" You smirked.

"You know I don't-"

"Yeah, yeah I know. But I think you'd feel better after closing your eyes for a bit. You need to not be thinking a mile a minute for once." You moved in front of him and grabbed him by his belt loops, tugging him gently toward the mattress. His face relaxed at this. The bed actually did seem enticing to him, in a strange way. You sat him down with you and he removed his shoes, followed by you pushing his shoulders back and climbing on top of him.

"I don't know how you wear those things 24/7," you said. He laughed bitterly, and you crossed your arms over his chest, resting your chin on them to look up at him. He reached up and rubbed your back softly in circles, moving his other hand up to rest on your head and run his fingers through your hair. You leaned forward suddenly, hovering just above his lips and looking into his eyes. He smiled and met your mouth with his. The kiss was gentle and slow. Your heart swelled when you pulled away and you tucked your head under his chin.

He held you like that in silence until you fell asleep, leaving him to worrying about your trip. He knew he couldn't control you, and he shouldn't try to. But he couldn't help but worry as he glanced down at your peaceful form. Humans were such delicate, sleepy creatures. He found it a combination of amusing and beautiful. You had shifted about in your sleep so you were now curled into his side, your arm grasping onto him, stretching across his waist weakly in your sleeping state. If Mason did anything to you there would be hell to pay. But he had to let you make your own decisions. He layed there with you until the morning.
