So this is a prompt I wanted filled but couldn't find anyone so I tried myself. First FF I've ever written so x I hope you enjoy!

"Fuck." Dean breathed decidedly. "Perfect. Good work Cas!" The sarcasm was not lost on the Angel.

"Dean, you said to get us somewhere the vampires couldn't reach us." Cas gave Dean a head-tilting stare, confused by Dean's unhappiness.

"Yeah I did, but this is not a good choice in hiding places!" Dean tried to wave his hand around, but his arm was stuck in between his and Castiel's chest. The hunter and angel were in uncomfortably tight quarters, zapped into a small (very small) closet. Dean wasn't 100% on the location, but he was fairly certain they were still in the warehouse they were investigating. What team free will hadn't expected when they broke inside was the nest living there. They had come during the night, and when they opened the inner door with a large thrum, the team suddenly had quite a few very angry eyes on them. In a desperate attempt to ensure they kept living past the night, Dean devised a quick plan for Cas and him to distract the fanged freaks while Sam made a run for the Impala, and all of their weapons.

The number of the nest was way to large to take on unarmed, even with an angel. After a valiant run around the floors and up a level or two, the small horde cornered Dean and Castiel.

"Uh, hey Cas. Think you can get us out of here?" Dean glanced over to the angel. Castiel looking as collected as ever grasped Dean's arm and there was a bright flash. The next thing Dean knew he was face to face in an inclosed space with less room then a coffin, if Dean had to wager. Castiel's warm breath fell against his cheek for a second before it occurred to Dean their predicament.

"Alright. Well. We're safe enough now, so can you zap us to a larger room?" Dean shifted uncomfortably, his entire body pushing against Castiel's. After the angel made no immediate response or movement, Dean started to get nervous. "Uh, buddy? Any time now." Dean stared hard at the angel.

Cas turned his head and looked down. Dean would swear he looked embarrassed, but he was fairly certain angels didn't have that emotion.

"I can't" Cas said. He started fidgeting,"I can't move my arms, and it is required in this vessel for additional movement to perform tasks." Cas turned his head, eyes meeting Dean's for a second before looking up at the top of the closet, suddenly very interested in the spider web there.

"I am not staying here" Dean proclaimed, and began to worm his other arm towards the door. In the attempt to grab the door knob, his thigh pushed forward, effectively pushing Castiel's legs apart, resting neatly between them. He wasn't sure, but he though he heard Castiel's voice hitch for just a second. Focus coming back to the task he was on, his hand reached the door and wiggled the knob. It turned easy enough, but when he pushed it wouldn't budge.

"I-I think it's locked from the outside" Cas mumbled.

"Great! Really solid work Cas!" Dean exclaimed, his annoyance building. Both of them were starting to get uncomfortable and restless. Dean shifted again to try and get the pressure off of one foot, and on to the other. Castiel froze, starting like a deer in headlights at Dean.

"What?" Dean started back. Cas gulped. Dean had seen that face before. He had seen it when he'd tried to get Castiel laid.

Dean wiggled his fingers and Cas still stared, unmoving. Not his fingers okay. He tried to subtly smell his own breath just in case, but found that task impossible. He shifted again and Castiel shut his eyes and turned his head, slightly trembling.

"Dean" Cas breathed. The realization dawned on Dean slowly. His hands weren't anywhere particularly exciting, but his hips were pressed securely into Castiel's. Dean shift again, quite innocently, and he watched the angel's reaction. Castiel's ears brightened with a a faint red hue. This time it was Dean's turn to get embarrassed. He tried with little success to shift away from Cas, only creating more friction and eliciting a moan from Cas.

Dean froze this time. Cas was starting to breath deeply, now looking very interested in a smudge of oil on the floor. Dean could feel Cas's erection pressing against him. Dean wasn't gay dammit, but he couldn't deny the excitement of the situation. Besides it wasn't like Castiel was actually a guy or anything. He was a big ball of celestial intent contained inside a vessel who happened to have a dick. Dean rolled his hips with purpose this time and Castiel squeezed his eyes tight.

"D-Dean" Castiel's voice was rough, the gravel and tone deeper than usual "what is happening to me. Am I ill?" Dean laughed a little at this. Castiel was the biggest virgin he had ever met, and he had met some severely catholic school girls. Dean grinned at that fond memory before getting back to the matter at hand.

"Yes Cas," Dean said seriously, "Very very sick. It's a terrible condition and there's only one cure for it" Dean ground his hips again, his own dick getting very interested in participating.

Cas trembled, and a whimper escaped his lips. Dean couldn't help himself after hearing Castiel's heavy breath, so he leaned in and licked the side of Cas's neck leaving a hot, wet trail.

"Dean..." Cas breathed. Cas pushed his hips back into Dean's, purely out of the body's need for release. Dean smirked into Castiel's neck. He nipped the side of Cas's neck and kissed it again. Dean wiggled his hand that had attempted to open the door up to Castiel's tie and loosened it to reveal more neck.

At this point they were grinding on each other like horny, desperate teenagers. Dean placed more butterfly kisses on Cas's collar bone, his one free hand moving up to his jaw. Dean stuck his thumb in Cas's mouth, feeling his harsh breath and hot wet tongue on the digit. Castiel close his mouth around it, humming contently enough.

This time it was Dean's turn to moan, his mind starting to wonder what that mouth would feel like on his cock. His dick began to leak inside his boxers, getting them wet with his precum. This is not how Dean imagined this day would go at all. His thoughts were brought back to reality when Cas started moving more sporadically and repeating Dean's name over and over in short breaths.

"Dean...Dean...ah! D-Dean please." Castiel wasn't even sure what he was asking for, but he knew he needed it like humans needed air. The knot in his belly was unfamiliar but not unwelcome. It felt unlike anything the angel had experienced since the dawn of his existence.

"Come on baby I got you" Dean bit Castiel's collarbone, leaving a blossoming bruise. Dean could feel he was getting close, but he absolutely refused to come before the virgin, "Come on Cas, let yourself go. I want to hear you screaming my name." He punctuated this last demand with a particularly rough thrust.

Castiel's breath was becoming unbelievably erratic and he grabbed Dean's coat, leaning into his chest. "Dean! Ah!" Cas buried his face into Dean's chest as he shook, cuming from the friction alone.

"I can't hear you" Dean reprimanded, his own release imminent.

"DEAN" Cas ground out loudly, moving his hips slowly as he road out the waves of orgasm.

Hearing his name called out so desperately from an angel of the Lord was good enough for Dean, and he came hard, bellowing as the orgasm hit him. He considered that he may have cum harder here and now than with the school girls, but that was a thought for another time as his legs turned to jelly. He probably would have collapsed if not for the horribly tight quarters that felt like they were starting to chafe, not that he'd ever admit it.

"Dean." Castiel looked hard at Dean. Dean's eyes opened, lazily looking over Castiel's sweat slicked face.

"What?"

"I'm...uncomfortably...sticky." Cas looked so serious when he said it, Dean barked out a laugh.

"Don't worry, as soon as we get out of here we'll get you taken care of." Cas looked so nervous and shy suddenly Dean's heart skipped a beat.

Without a second thought he leaned in and kissed Castiel's slightly chapped lips. Castiel's face softened, and eyes fluttered close, his lips parting slightly. It wasn't a kiss of passion or excitement, but very gentle and chaste.

Dean pulled away and just stared at Castiel for a long second. He was about to start over thinking the whole thing when the door suddenly flew open and they both fell, quite ungracefully, from the closet. Sam stood over them, eyeballing their state suspiciously. The bruise on Castiel's collarbone did not go unnoticed by the younger Wincester.

"Took you long enough Sammy!" Dean tried to sound annoyed as he stood up and brushed himself off. He looked behind him and Cas was already on his feet.

"Well I'm sorry you decided to hide in an unmarked closet on the top floor!" Sam decided to ignore the state he found his brother and the angel in, at least for now. "It was hell just to get here, and we don't have time to lolly gag." Sam thrust a machete at Dean just as a flood of vampires rounded the corner. Cas and Dean's eyes met briefly before they turned to take their fighting stance. It'll just have to wait until later they can continue it. Discussed. Briefly acknowledged with the certainty it would never happen again. Yeah, that last one is what Dean had meant .
