21. should have knocked (smut)

Cas finished rinsing off, then stepped out of the shower and ruffled his hair, shaking the water out of it. He was deeply relaxed from the soothing heat of the water and the gentle motion of the sponge.

"Hey, Cas, are you done in there?" began Dean's voice unexpectedly. The door opened, and Dean stepped through - and froze. He gaped at Cas's naked body, visibly caught off guard. "Oh...Cas. Shit."

Cas glanced down at himself. "I apologize. This must be uncomfortable for you. Shall I cover myself?"

"Sndkd - um - I..." Dean was pale. "I, uh, yeah, I'll just...I'm sorry, I should have knocked."

"No, it's alright." Cas grabbed a towel and wrapped it around his waist. "Better?"

Dean swallowed. "I was just wondering if you were out yet. Sam and I are...we've got a case."

Cas nodded. "I'll come." Walking into his adjoining bedroom, he pulled out a set of clothes and began to change. Dean's face flushed red as he averted his eyes, unable to keep from glancing at Cas's well-toned body and large member.

"Dean?" said Cas, pausing. He still didn't have any pants on, but he seemed perfectly unaware that it was unusual to walk around unclothed from the waist down. "Are you alright? You seem.. flustered."

"It's nothing."

"Are you sure? Your face is very red, Dean, and I can hear your heartbeat. And..." Cas frowned at Dean's crotch. "You appear to be experiencing arousal."

Dean gritted his teeth. "Cas..."

"Am I causing you discomfort? Do I need to help?" said Cas with a gesture at Dean's obvious hard-on.

"What? No! Cas, I'm fine!"

Cas stepped towards him, stopping an inch away and studying Dean's face. "Mm. I think I should help you." His member brushed against Dean's, causing the hunter to moan and bite his lip. "Is that alright, Dean?"

"...Yes. God, yes, Cas."

Cas pulled off his shirt, baring himself again and closing the distance between them. He kissed Dean passionately, running his hands down the hunter's sides and sliding them into the front of his jeans. Dean groaned as Cas pushed him down onto the bed, hastily undressing him and kissing his neck. "Fuck, Cas," Dean gasped, closing his eyes, "Cas...oh, God, yes."

Cas grinded against Dean, humming with pleasure as his member hardened. Dean moaned, arching his back, his muscles clenching.

In a husky voice, Cas said, "Dean, tell me what you want."

"I - I want you. I want you inside of me, Cas. God, I need you.

Cas touched two fingers to Dean's lips. "Suck," he growled.

Obediently, Dean took Cas's fingers into his mouth, licking and sucking until they were thoroughly coated in saliva. Then Cas kissed him passionately, entering Dean's ass with his wet fingers. Dean made a choked sound, writhing beneath Cas's body as the angel continued to grind against him, circling his hips and finger-fucking the hunter with lust in his blue eyes.

"Cas," Dean moaned. "Fuck...oh, yess, Cas, god yes. Oh, God... C-Cas." He gasped for breath. "Fuck me, Cas. Fuck me until I can't walk."

"Say please," growled Cas, removing his fingers and aligning himself with the hunter, deepening the kiss.

"Nng - fuck, Cas, please. Please fuck me, oh, please Cas. God, I need you."

"You're so beautiful when you beg." Cas entered him, bucking his hips and rocking Dean's sweat-slick body. Dean's moans became screams as he clutched Cas's back, his eyes screwed shut. "Oh, Cas, Cas! Fuck, Cas, yes!"

Cas panted, fucking Dean harder. "Nng... ah... oh, god Dean. Oh my god." He could hardly breathe, but he never broke his rhythm. "Dean...oh, jesus fucking christ..."

Finally they both came, going limp and collapsing next to each other. Their chests heaved as they fought for breath, still in the afterglow of what had just happened.

"Wow," gasped Dean.

Cas smiled. "We should do that more often," he told the hunter.

"Hell yes we should."
