Destiel One-Shots

Unfaithful

AU: Castiel catches Dean cheating on him.

(AN: It's okay, I hate myself for this one too. You're welcome. :))

"Why do you always have to do this? Why do you fucking demand my attention then just leave me? Why do you have to play with my heart like it's a goddamn toy? It doesn't make sense, Dean! Just, why? I can't figure it out. You do this to me every time I give you another chance. You always fuck it up someway or another! Just because you're Dean fucking Winchester doesn't mean you can treat me like shit. I'm not one of those fucking girls that drool all over you because you're the quarterback. I'm not just one of your little throw-away fans," Cas screamed at Dean between sobs, exasperation openly exposed on his face, melancholy and anguish clouding his deep blue eyes.

Castiel felt like there was a fire quickly growing inside of him like angry flames engulfing dead brush on a dry, hot afternoon in the middle of summer; like his entire heart and soul were painful being seared by his hurt and sorrow, burning him alive from the inside-out. Even if Dean and Cas did get over this, it would never be the same. This whole damned mess had permanently branded him. There would always be a scar on his heart, a gruesome tear in his soul, a piece of him lost forever.

Dean's eyes went wide and his face pale. He never meant to do this to Cas, the love of his life, the greatest thing to ever happen to him, the most wonderful person in the whole world. Castiel didn't deserve this. Castiel didn't deserve someone like him.

If only he hadn't gotten drunk and been a fucking idiot, none of this would've happened. He ruined it. He royally fucked up this time.

*That night*

"Dean, you know I hate parties with a burning passion," Cas whined for what seemed like the millionth time that day. They had both been invited to Uriel's annual Halloween get together, which was really just a typical senior party. Castiel wasn't friends with Uriel and, to be honest, hated the people he hung out with; the popular jocks that bullied him in middle school and early high school. Dean, however, had absolutely nothing against him personally and agreed to go, despite Castiel's many objections. Castiel found Dean's choice perplexing, considering Dean never went to these parties when he was invited, but didn't think too hard about it. Dean had always gotten along more with those people anyways, being the beloved quarterback, plus he naturally fit in no matter where he went.

"Cas, baby, it'll be okay. I'll be right there by your side the whole time." Dean reassured him as they pulled into Uriel's already packed driveway, full with cars and it was barely time for the party to start. Castiel groaned.

"You better be. I can't stand like 98% of these people, you know that." He was seriously starting to regret the decision to accompany his lovely companion. He was only doing this because Dean wanted him to. He wasn't a party person, not at all. The mere thought of even attending churned his stomach and put a bad taste in his mouth.

When they stepped up to the door, an already buzzed Uriel opened the door wide and welcomed them in. Castiel didn't feel very welcome; Uriel made sure to shoot Castiel an evil smirk when Dean wasn't paying attention. He had a horrible feeling about this. Dean was a natural, he new everybody and socialized well; all brilliant smiles and friendly pats on the back. Castiel just wanted to get this whole thing over with, he felt like a fish out of water. He had never been so uncomfortable. He sure wasn't going to have much fun, but he hoped Dean would enjoy himself. Oh, the sacrifices he made for that boy.

Castiel followed Dean around like a lost puppy. Dean was handed cup after cup. He passed Castiel a cup full of beer and encouraged him to loosen up, take some of the edge off and he'd feel better. Castiel smelled the awful concoction and set it down at a near table when Dean turned his attention elsewhere. If Dean was going to end up shitfaced, he wanted to make sure he got home safely.
