AN: So, this was supposed to be a one-shot that I knocked out so I could stop trying to pair Sam and Cas in my All's Fair sequel. It turned into this. I just don't understand why I can't let them be happy. Also, Sam's kind of a dick in this story. Just pretend it takes place when he had no soul or something. Sorry "Sam Girls" I kinda destroyed your man in this. Oh well, artistic liberties and all that.
1. Sam
If he ever caught them like this, it would be the last thing Sam ever did.
Not that Sam was complaining. It would be worth it, but he'd just like to live long enough to do it again.
What is it, you ask?
Well, Sam could tell you that he definitely didn't have Cas' hands pinned above their heads in a single strong grip, as his other hand pressed hard to Cas' ribs, moving ever lower with the rocking of his hips.
He could tell you that he was a good brother that respected celestial beings belonging to his older sibling, or that he was too moral to have his cock shoved so far up Cas' ass that his jutting hip bones left marks on the inside of the angel's thighs.
He could tell you that, but he'd be lying on both counts, and Sam was nothing if not honest.
As it was, Cas seemed to be enjoying himself, and Dean had mentioned something about making the angel comfortable. Sam was fairly confident that this was well outside of the parameters of Dean's intended command, but hey, at least Sam was diligent in making sure Cas was well taken care of.
As mentioned before, Cas really seemed to be enjoying himself.
His legs wound around Sam's back without any coaxing or direction. They were an awkward fit, Cas' shorter limbs not being able to compete with Sam's greater range of motion. There were three things that worked really well for them, though.
Missionary, Cowgirl (or boy, depending on how literal you want to be), and doggie (provided Sam didn't mind spreading his legs a bit wider to get down to Cas' level) and Jesus fuck, it was good.
In fact, they worked almost too well. There were times when Sam switched their positions just so he didn't bust too early and spoil it.
He knew Cas was a virgin, and part of him felt like he should feel like shit for snatching this opportunity from under Dean's nose, but Cas was more than willing, and Sam wasn't about to complain. Seriously, who passed on the chance to deflower an Angel of the Lord (or…whatever)? Plus, it had been a while for him, and the way he saw it, Cas could probably use a little loosening up (in more ways than one) if he was planning on jumping in the sack with Dean.
Also, Sam had a thing about sloppy seconds. Especially his brother's.
Pushing the thoughts of Dean from his mind, he smacked his hand down on Cas' thigh and pulled away, flopping down onto his back before yanking Cas' body over his own.
The angel was compliant as he settled over Sam's lap, working his hips back and forth under Sam's encouraging hands. The cleft of Cas' ass slid over Sam's slick shaft, and Sam gripped the base of it, raising it up and guiding Cas down onto it. The angel threw back his beautiful head, and Sam pretended not to hear his brother's name on his lips.
Thrusting upwards, Sam saw stars; Cas' body was so perfect. He had hips that didn't fucking lie (whatever the Hell that meant), lips sweet as sin, and an ass tighter than any wrecked pussy Sam's ever had.
Cas' hips rotated above him, and Sam couldn't stop the involuntary squeeze of his hands on Cas' thighs. His blunt nails dug into the pale skin, leaving crescent shaped bruises that would definitely be there tomorrow.
'Good,' Sam thought, 'let Dean see.' He wasn't really sure why it felt so good to be able to hold this over Dean's head, but it afforded him some power over his brother that he'd never had, and that thought was definitely appealing.
Sam knew for a fact Dean had never experienced Cas like this.
He was too afraid.
If only Dean could see his angel now.
AN: So, I have a Supernatural calendar in my room and Dean is the picture for February. He has this exasperated glare on his face and I feel like he's judging me for writing this and for putting him and Cas through so much shit when I pair them together. Then I lift the page to March and it's Sam with this huge smile on his face. It makes me feel justified in my actions. Thanks Sam.
