"Dean."
Dean opened his eyes, which he had just closed seconds before, to see Castiel looking down at him, his ever-intense gaze doing more to pin Dean down into the too-soft hotel mattress than the actual weight of the angel's body.
"Don't move."
Dean held that gaze, his eyes burning with their own desire-fueled intensity, as he attempted to get his breathing under control.
"Okay?" The angel asked, obviously waiting for confirmation before continuing.
Dean didn't trust his voice just then, didn't think he was actually getting enough oxygen to even speak anyway, so he just nodded, keeping his eyes on the angel, curious about what he was about to do.
The angel slowly lowered his head back down toward Dean's neck, to the same spot he had just found, the one that had made Dean groan and squeeze his eyes shut as he arched his back, pressing his head deeper into the bed in the first place. It wasn't that this spot on his neck was particularly sensitive, no more so than the rest of his neck. It was the fact that Cas's stubbly chin and cheek had rubbed against Dean's neck and jaw, and damned if that wasn't the hottest thing he had felt in his entire life.
Cas currently had a bit more stubble than usual, somewhere between the faint dark shadow that would invariably begin to appear a few hours after he shaved, and the scruffy but softer beard he had had when he returned from Purgatory. At the moment, he had only skipped a day of shaving, maybe two, and the feel of that prickly stubble against Dean's skin was definitely doing things to Dean.
The angel kissed the spot softly at first, tentatively touching his lips to Dean's skin and ghosting them across the spot in barely-there touches, before opening his lips a bit further to let his tongue peek out just enough to get a small taste of the skin. Gently sucking and kissing the spot for a minute while his right hand crept its way slowly down Dean's torso, exploring every plane and dip along the way.
That hand had started at the back of Dean's head when the angel had first started kissing him and pushing him backwards towards to bed. Once Dean had felt the edge of the bed pressing into the back of his legs, Castiel had started leaning forward, bending Dean backward and using his considerable angel strength to slowly lower them both down onto the bed. Supporting the weight of both men's bodies with only his left arm, his right hand had stayed on the back of Dean's head, firmly guiding the angle of the head to deepen the kiss while at the same time keeping Dean pressed firmly to the angel's body, controlling the speed of his decent into the mattress.
Once Dean's back had gently touched down, Cas had pulled back again slightly, lifting himself away only enough to make a few inches of space between their bodies, all of Cas's weight supported by his left arm on the bed, as well as his two feet still on the floor.
It had occurred to Dean that Cas would rock at doing one-armed pushups, not even having to move his arm under his core or angle his body to adjust his center of gravity over the arm, like humans had to do. He had lowered them both down easily enough, even though the arm that supported them was well to the side, and had lifted his own body up just as easily, hovering it directly over Dean's, keeping their faces even so that he could maintain eye contact as he grabbed the hem of Dean's t-shirt and tugged it upward with his free hand. Dean had squirmed around a bit then, arching and reaching up to help Cas take his shirt off.
After the shirt had been carelessly dropped to the floor, Dean had reached up, grabbing Cas's face in his hands and pulling it down to continue their kiss. Cas had come down eagerly, sliding his free hand to the back of Dean's neck. There it had remained, even after Cas had broken the kiss to instead focus his mouth on Dean's neck, where he had discovered the spot that had made Dean react so dramatically.
That hand was moving down Dean's torso now, rubbing, caressing, squeezing, and occasionally scraping nails across every bit of torso that Cas could reach in the space between his own body, which he still held aloft, and Dean's. His mouth stayed focused on Dean's neck, experimenting with different touches and movements, trying to pinpoint the cause of Dean's extreme reaction so he could elicit more of it. When the chest-exploring hand reached the buckle of Dean's belt, Cas opened his mouth wide enough to bite down on the spot, making Dean groan even deeper still.
Dean was dizzy with need. He moved his hands from the angel's upper arms, which he had grabbed and squeezed in an attempt to stay still, and reached down to his own belt, intending to help the angel open it as quickly as possible.
Castiel pulled his head back away from Dean's neck, again looking Dean in the eye. "I said don't move," he reiterated, a smile on his face.
Cas's smiles, so rarely seen, had always affected Dean whenever they appeared. They never made the angel's eyes any less intense. Depending on the smile, they may change to intensely fond, or intensely happy. This particular smile was a smirk of amusement, the angel's face tilted slightly down so that he was almost looking up at Dean through his lashes, and just made Cas's eyes look intensely sexy.
Dean obediently pulled his hands away, grabbing at the generic hotel bedspread on either side of him and fisting it in a white knuckled grip. Cas lowered his head again, this time to Dean's chest right above his heart, rubbing his rugged stubble across the skin as he peppered it with periodic kisses, moving across and downward at an agonizingly slow pace. Dean watched him move, looking down at the top of the angel's head, occasionally getting a glimpse of his face in profile as he tilted his head this way or that in his mouth's exploration of Dean's body.
When he had moved down low enough, Cas lifted his second arm off the bed and it joined the first, working the belt buckle open as his lips continued their maddeningly slow pace down Dean's body. When the edge of the angel's stubbled jaw moved across the peak of his right nipple, Dean cried out wordlessly, something between a groan and an exclamation. The angel licked at the nipple and then bit down lightly before continuing his way down.
By the time his lips had made it to the area just above Dean's belly button, Cas had managed to open the belt, unbutton the jeans, and move the zipper all the way down, discovering as he did so that Dean wasn't wearing anything under the jeans. At all. He pulled his face away from Dean's body then to look him in the eye again as he began to tug down on Dean's jeans. Dean lifted his hips off the bed and Castiel pulled the jeans off and stood up in one movement. He dropped the jeans to the floor as he looked down at Dean's now completely nude body, taking it all in.
With the bed spread still in a death grip, staying as still as he could, Dean could only speak.
"Cas," he said, breathless voice dripping with need.
The sound seemed to pull the angel out of some sort of reverie. He tore his eyes away from Dean's body and again looked him in the eye. The mutual desire the angel saw there was more than he could take. He immediately moved toward the man, dropping down on his knees to the floor in the space between where Dean's lower legs hung off the edge of the bed. His hand found Dean's cock a split second before his mouth did, grabbing it and guiding it into his eager mouth. He began to bob his head, sucking and licking as he did so.
Dean couldn't hold himself back any more. He reached down and curled his fingers into Castiel's dark locks, eliciting a small chuckle from the Angel's otherwise occupied mouth. He obviously hadn't expected the man to last as long as he had in following his instructions. Dean took this as permission to move, and began to tilt his hips ever so slightly to meet each of the angel's downward movements.
Cas moved a hand to each of Dean's knees, gently pushing them apart as he moved his body closer to Dean's, his head continuing to bob. After he had spread those knees enough to get his body as close as he could to the human's, he slowly slid his hands up the inside of Dean's thighs, feeling the tension and movement in the muscles as the man rocked into his mouth. At reaching his groin, the angel moved those hands to Dean's hips, pulling his body closer to the edge, and deeper into his mouth, continuing to bob his head at a steady pace, and sucking more of Dean into his mouth with each downward dip.
Finally, on one particularly deep dip, in which Dean felt himself go deeper into the angel's mouth than he thought should be possible, deep enough that the angel's stubbly chin pressed against the exceedingly sensitive skin of Dean's sack, and he could feel the muscles of the angle's throat working around him in a swallow, Dean yanked hard on the hair that he had been running his fingers through.
"Cas," he warned insistently in a determined, if slightly winded voice, continuing to tug up on the angel's dark locks.
The angel obediently tilted his face up to look at the Winchester, keeping the cock firmly in his mouth as he did so, though thankfully pausing the movements of his tongue and throat, though those intense eyes combined with the knowledge that he was currently deep in the angel's throat was doing nothing to calm Dean, which is what he really needed at the moment.
"If you want me to fuck you, you had better stop that."
The angel's eyes glazed with obvious lust, and he pulled back, letting Dean's spit-slicked dick slide slowly out from between his wet, glistening lips. It took him only a moment to regain focus, though; shaking whatever image that had overtaken his mind out with an actual shake of the head. He refocused his gaze on Dean, an almost smirk appearing on his mouth.
"Actually, I thought I'd fuck you tonight."
That phrase coming from those glistening kiss-swollen lips, combined with the ardor of the angel's focus would have made Dean's knees give way, had he been standing. Instead, he simply growled "Oh, god," and curled his fingers again into those dark angelic locks, pulling down while arching his hips up toward that mouth again. The angel maintained eye contact while lowering his head back down at an agonizingly and deliberately slow pace, making Dean's anticipation build with every passing millisecond, flooding the hunter with need until he was shaking all over. Just as began to part his lips, his tongue about to touch the tip of Dean's achingly hard dick and welcoming it back into his warm, wet mouth, a car alarm went off.
