A/N: Okay, my headcanon is that Cas and Dean end up together after the Supernatural series is over, with Cas becoming human. So this takes place then. Was listening to Faster by Matt Nathanson when I thought of writing this, so yeah haha. This is pure sex.
You Taste Like Sunlight
It ended up like this after he and Castiel decided that dinner in the fancy and expensive restaurant was too cliche and thought that having sex in the impala in the parking lot was a much better idea.
Besides, Dean was horny the whole day, after all, and apparently so was Cas. And he couldn't hold it all in anymore, after seeing the brunette in that suit of his.
They were in the backseat of the car, Castiel on top of him. The brunette was kissing the soft crook of his neck while the sandy-blonde cradled his hips. With each brush of Cas' lips on his neck becoming hastier and hastier.
Cas started to grind against him, which made him pull harder on the hem of the ex-angel's dress shirt. "Fu-uck!" Dean groaned. Castiel pulled back and saw his flustered face.
"You okay?" he whispered, in that gravelly voice of his.
"Shut up and kiss me, you son of a bitch," he said. He smirked at him, and with his blue eyes and messed up hair and impossibly-gorgeous face, Dean thought it must be a crime, the way he was looking at him.
Castiel quickly removed his tie. "Do the same," he commanded. Dean obliged. Cas took one and used it to tie Dean's wrists to the top handle above one side window of the impala. The other one was to function as a blindfold. Castiel liked playing these kinds of games. Dean heard the condom packet rip.
While he was tied up, Cas took off every piece of clothing on the both of them. "Good thing the glass is really dark tinted. I don't want people seeing what I'm about to do to you," he said roughly, getting out the lube. Dean swallowed hard.
"You know, Dean, you're really irresistible when you're all hot and bothered like this." He guided the hunter's legs up.
"Y-you are too. Um. That." Ugh, Dean. What the hell was that, he thought to himself. He cleared his throat. "Hurry up, Cas. At this rate I'm go-oh."
Castiel began playing with his opening. First with a knuckle and then two. Dean whimpered. He massaged it more.
"Oh god, Ca-aas," he cried. It really turned him on, seeing the sandy-blonde flustered with desire. He put a generous amount of lube on his cock.
"Are you still functioning properly?"
"I can't believe you are doing this," he panted.
"What, Dean?"
"Oh for the love of...J-Just fuck me, please."
Castiel obliged. He thrust slowly. Dean's cheeks and lips were pink and his mouth was half-open.
He thrust more now, swaying his hips. "Yes, Cas! Ah, fuck," he gasped, and Cas couldn't help but see stars. A minute later, he found his prostate and Dean moaned, sparks in his eyes."Oh-OH! CAS! Hhhnnhh."
Castiel found Dean's hands and intertwined their fingers together. He came a few moments after.
He slid out of Dean, quite dazed. He removed the hunter's blindfold. "That was good, huh?"
Dean composed himself for a second then gave a mischievous grin. "That was glorious. But we're not done, are we?"
Castiel smiled, leaning back and allowing Dean to go on top of him. Maybe he was up for one more round.
