Part IV
Dean was the first to wake up. His mouth and throat were parched and he was sure a blacksmith must have opened a shop in his head while he was asleep, judging by the hammering behind his forehead.
He groaned and turned to his side. Great. His arm had fallen asleep.
Cas was still fast asleep, the head comfortably cushioned by Dean’s asleep arm, stopping the blood flow with a gentle smile.
Dean groaned again before he tried to extract his arm from underneath his – yes, his - boyfriend’s head and tried to shake some life back into it as he sleepily shuffled into his bathroom.
He needed something to stop the headache. Dean rummaged through the cabinet until he found some painkillers and downed them with some water from the sink. He brushed his teeth thoroughly- he didn’t really want his breakfast taste like tequila, and almost fell when his arm buckled underneath his weight, proving they weren’t really back to normal, as he braced himself on the sink, staring into bloodshot, tired eyes in the mirror.
Wow. They had really done it. They actually had gone to that party- Together. And it hadn’t resulted in the apocalypse. Wow.
He stuck the toothbrush into his mouth and grinned at his reflection, a mixture of excitement and nausea spreading in his stomach.
“Dean?” Dean almost didn’t catch the weak calling through the pile of sheets and pillows and the bathroom door.
“I’m in the bathroom!”
Dean heard the sound of naked feet on the floor and then there was a sleepy Cas at the threshold, rubbing the sleep out of his eyes.
“Morning, sunshine, got a nice hangover, too?” Dean teased Cas around the toothbrush in his mouth.
“No words. Water. Please.” Cas groaned and bent over the sink.
Dean took care of his terribly hungover boyfriend in a commendable way. He supplied him with aspirin before pushing him into the shower and under the hot stream of water, following closely behind.
They washed each other’s hair, still sleepy, and stayed maybe a little bit too long in the shower, but Dean just couldn’t tear his eyes off the droplets, running down Cas’ smooth skin.
Freshly showered and almost human again, they fell back in bed.
“Cas?”
“Hmm, Dean” Cas’ eyes were already drooping again. In his defense, it wasn’t even noon and a few more hours of sleep weren’t entirely unwelcome to Dean either.
“I …” Dean got lost in the sight of his boyfriend, who was lying with still damp hair in his bed, wearing his t-shirt. How come he has never noticed those incredibly long, dark lashes before? The night before felt like a dream. Cas had looked so damn fine. And Cas was his. And everyone knew that, now.
Dean nuzzled Cas neck and sucked in the scent of his own shower gel, but could still make out Cas’ own scent underneath that. He wound his arms around Cas’ middle and pulled him closer.
“I just still can’t believe we actually did that, yesterday” Dean murmured into Cas’ neck and kissed his way up to the soft spot behind his ear.
Cas smiled with closed eyes, “Me neither, Dean.”
“Now everybody knows that you are mine” Dean whispered and bit softly into the skin beneath his Cas’ ear.
Cas shuddered. “Hmm, only yours … and you, you…” Cas got lost in his thoughts and after a few moments of silence, Dean propped himself up on his elbows to look into Cas’ face.
“And I am yours. Only yours.” He finished Cas’ sentence, furrowing his brow. “Right?”
Cas slowly opened one eye and observed Dean’s face with a thoughtful look, chewing on his lower lip.
“Yes?” he finally whispered.
Something fell in Dean’s chest as soon as he realized that Cas, even after last night, was still so very insecure about the two of them. But who could blame him? Dean was not really famous for his stable and long-lasting relationships.
Dean looked at Cas, really looked at him, and saw it. He shook his head and huffed.
“Cas, look at me.”
Cas slowly opened his other eye, too, and blinked up at Dean, who was now kneeling beside him.
“Yes. Okay? Don’t forget that. I. Am. Yours.” He stressed each word with a kiss, to Cas’ forehead, to his cheeks, to his nose, and finally, to his mouth.
Dean kissed his way down from Cas’ mouth to his jaw, then, and further to the spot underneath his ear, down his neck until he reached Cas’ collarbones. How the fuck could everything about this boy be so fucking attractive? Even his collarbones were sexy. Bones.
Dean shoved Cas’ t-shirt up to his shoulders, kissing his collarbones, his nipples, to which he paid extra attention, swirling his tongue around and taking them between his teeth until they were hard and the skin on his chest and shoulders burst out in goosebumps.
Dean glanced up to see Cas’ face, with his teeth still around one nipple, and grinned as he saw Cas’ eyes closed and his mouth slightly open, face relaxed.
Dean ran his hands up and down Cas’ sides and tracked Cas’ trail of dark hair on his stomach with kisses, until he reached the waistband of Cas’ boxers. But when Dean slipped his thumbs underneath it and continued kissing his stomach, Cas started fidgeting, moving uneasily before sitting up.
Dean glanced up and met Cas’ worried and doubtful look.
“Relax, man” Dean laughed and pushed Cas back into the mattress before he nuzzled the soft skin above Cas’ knee with his nose and dragging his tongue up Cas’ thigh, but as soon as he came close to his boxers, Cas sat up again.
He pulled at Dean’s arms, reaching for his nipples and ran his hands over Dean’s thighs, but Dean sat back abruptly, withdrawing himself from Cas’ impatient fingers.
“Cas, would you please relax? What the hell is going on with you?”
“But, Dean” Cas whined, reaching for the waistband of Dean’s boxer shorts, but this time Dean took Cas hands into his, holding them still.
“Cas, what’s wrong?” Dean asked, suddenly serious, Cas fingers stilled in his hands.
“What about you?” Cas mumbled and averted his eyes, his lashes long and dark on his cheeks.
“Hm?”
“I can’t just … just lay here and … Please, Dean, let me give you…” Cas blushed, opening and closing his fingers around Dean’s.
“Yes, Cas, you can. You just lay down here, now, and let me worship you. Sorry, no excuse accepted.”
“But-“ Cas protested but Dean didn’t let him finish that sentence.
“No. Listen. You … you always do so much, to me, for me, so just … just let me … ugh, Cas. I just want to…” Now Dean blushed as well, giving Cas’ fingers a little embarrassed squeeze before he fell back down on his knees and hands, pressing his face into Cas’ neck, seeking reaffirmation in Cas’ oh so familiar scent.
It was so much easier when he didn’t have to look into those big blue eyes, because then he could actually try to concentrate.
“I want to see your body” Dean murmured hesitantly, stroking the skin stretching between Cas’ neck and shoulder.
“You are really … I think you are … - I haven’t seen your body. Like. Since we started this, I haven’t really … seen your body” Dean’s face heated up. Maybe it had been a dumb idea. But then there were shy arms around his chest, hesitantly holding him, and Dean sighed, shaking his head about himself.
“I want to see you, I want to see every inch of you, everything, in detail, and you … You just looked so incredible yesterday – well, I mean you always do, but – no, I mean, please. Let me … let me do this to you. For you. Please.” Dean murmured into the skin behind Cas’ ear, pressing small, warm kisses onto his neck.
“O-Okay, Dean. Whatever you want.” Cas stuttered, goose bumps all over his body, his fingers like feathers on Dean’s shoulder blades.
Dean pressed another soft, but with purpose filled kiss on his lips to remind him to stay in position before he laid Cas out underneath his hands on his bed.
Dean started – again – with the neck. He kissed every inch he could reach, down the left arm to Cas’ fingers, which always surprised Dean again with their strength and beauty, and repeated the whole procedure on the other arm.
Then he bent down to Cas’ ankles, resulting in Cas fidgeting again until Dean set a calm hand onto his hip.
He kissed his way up over Cas’ strong, lean runner’s calves, to his thighs, covered in soft, dark hair, which he didn’t mind because he was so lost in the world of Cas’ soft skin, toned, lean muscles and – oh god – the scent.
With every passing moment Cas relaxed slightly more, and by the time Dean had kissed, bitten and licked his way down Cas’ chest to his sharp hipbones, Cas’ hands were opening and closing next to him on the mattress, the mouth open and the eyes half-lidded.
Dean finally, finally pushed his thumbs underneath the waistband of Cas’ boxers, tracing the irresistible V of lean muscles, until Cas was a mess, making little, needy sounds he probably would be ashamed of if he had all his five senses together right now.
It almost took Dean’s breath away when he looked up to see Cas lying there, all relaxed and moaning, so very beautiful, looking so … secure.
It dawned to him that Cas had always felt the most secure around him, but still never had let down the walls completely, and It almost pained Dean physically to think about that.
He could trust Cas, he knew that, he just knew. And that meant something. Because, you only trust family. Right? But Cas …. But Cas still couldn’t trust Dean completely, for whatever reason.
Dean rested his head on Cas’ stomach, pushing both his arms underneath Cas’ body to completely embrace the boy, before he pressed his lips firmly on the trail of black hairs, directly beneath Cas’ belly button. The muscles in Cas’ stomach fluttered and Cas took a shuddering breath.
“Cas” Dean whispered, both hands on Cas side, still holding him in his arms.
“Hmm” Cas hummed contently in response.
“Cas, I … I …”
“Hmm, Dean, what’s wrong? You don’t have to continue, if you don’t want to” Cas responded, the voice heavy but understanding.
Dean rolled his eyes at that and at himself. Well, Winchester, there are only few things you can’t handle, but forming words into sentences to express your feelings? Not really your division. But, Dean could show him. He was so much better in that, anyways. And that’s what he did.
He pushed down the waistband of Cas’ boxer shorts and took in the sight. By now he was used to it, more or less, but it was still a strange feeling to see a reddened penis awaiting him instead of a vagina. But Dean actually really didn’t mind, it was just something different, not something less.
He really liked his own dick, therefore Cas’ dick had to be like the prettiest thing he had ever seen, right?
Cas had tried giving Dean a blowjob, once, but Dean had awkwardly stopped him and said he just didn’t feel quite ready for that. But now he found himself in a situation where there was a red pulsing, hard cock in front of his face, his boyfriend’s cock, and Dean was a little bit nervous, hah, who was he kidding? Very nervous, as he stuck out his tongue carefully and touched it tentatively to the base.
Cas shuddered, it was warm, really warm, and surprisingly firm, but the skin was oh so very soft. And Cas smelled … good. Kind of like himself, only deeper, darker, muskier.
Dean gained some courage and licked a stripe up the underside of Cas’ dick, up to the top, caching some of the precome gathering there with his tongue. The taste was kind of salty and had a distinctive note, which made Dean wince first, until he got used to it and licked the remaining precome off the tip.
Cas’ hands rose and wound themselves into Dean’s hair, desperately searching for something to hold on to.
“Oh – oh, Dean” he groaned, lifting his hips slightly. Thankfully, he wasn’t doing anything too wrong here, Dean thought relieved.
Dean couldn’t help but to smile wickedly and start licking stripes all around Cas’ cock, feeling the blood rushing and pulsing underneath the skin under his lips and finally sitting up to examine his work not even trying to hide his pride.
Cas’ dick was red, and hard, and very, very slick. And Cas was already a wreck, panting and writhing underneath Dean’s eyes, a film of sweat covering his whole body, running his hands through Dean’s hair again and again, scrabbling for a hold on to reality.
“Dean, i-if you don’t want to do that, it’s, it’s really – ah – fine – ohgod!” Cas moaned as Dean cut him off by suddenly placing his lips around the head of Cas’ dick, letting his tongue lick away the precome pearling there again.
“Oh, would you please just shut up, Cas, I won’t say it again” he whispered with a smirk, and took Cas’ cock in his mouth as far as possible.
Cas actually growled at that, gripping Dean’s shoulder with one hand, the other one lightly resting on Dean’s head, as he started to carefully and slowly bob his head up and down, the tongue playing with the vein pulsing on the underside of Cas’ dick, turning Cas into a babbling mess.
“Dean – I … oh, yes, right there, Dean – ah.”
Cas’ pelvis thrust upwards, pushing the dick in Dean’s mouth further down his throat and making him gag. Dean popped off Cas’ cock and took some deep breaths through his nose before he fixated Cas onto the mattress with both his hands.
“Oh, oh god, sorry, I am so sorry, Dean, I didn’t mean to, oh god I am so sor-“
After the shock and the gag reflex had subsided, Dean took Cas back into his mouth, but this time he let his head sink down further and further, until the head of Cas’ dick hit the back of his throat again, but this time Dean was prepared and he concentrated on overcoming his gag reflex.
Spit ran down his chin and his lips ached, he already felt the soreness creeping into the muscles of his jaw and tongue, but all that didn’t bother Dean much when he could hear Cas making sounds like that. Small and needy sounds, barely a whine in the back of his throat. And this big, hot hardness in his mouth, laying heavy on his tongue, completely at his mercy.
The muscles in Cas’ stomach fluttered and Dean let him take careful, controlled thrusts against the back of his throat.
“Oh, oh my god, Dean, that is the best – oh – Dean, I think imam-“ Cas stuttered and tried desperately to stop Dean from moving, clutching to his shoulders, gripping his hair, fixating Dean in the position he was in, completely still now.
But Dean had to swallow, thanks to his reflexes, and Cas’ eyes flew open, his pelvis thrust against Dean’s face, driving his dick even deeper down Dean’s throat, and he came with an almost animalistic, deep groan down Dean’s throat.
Dean had no other choice than to take and swallow, and this time he almost did throw up. Almost. This exact moment Dean suddenly understood why the girls he had been with always had been so reluctant to swallowing. His throat burnt and tears had been spilling out his eyes, streaking his cheeks. As soon as he got in his first breath, he grabbed the water bottle standing next to his bed and tried to rinse the taste out of his mouth.
Cas had finally found consciousness again, bolting to sit upright and, oh no, Dean already knew that look.
“No, no. Cas. Don’t. Everything’s fine” Dean croaked, “Don’t you dare to say sorry now” he added to wipe that worried, sorrowful look off Cas’ face. Dean smirked.
“Maybe was a little bit much for a beginner like me, but hey” Dean snuggled back to Cas into the bed and under the covers, “at least I tried it. I hope I wasn’t too bad.”
Cas stared at him with big, unbelieving eyes.“Bad?” he finally managed to say, his voice still low and raspy of arousal and bliss. His face slowly lit up with a huge smile and he slung his arms almost too tight around Dean.
“Dean, that was … phenomenal. Thank you. Thank you. Thank you for being here, thank you for having me, thank you, for everything.” Cas hid his face in the crook of Dean’s neck but he still could feel him smile against his skin.
“Well, thank god, and – you are welcome, Cas” Dean laughed and finally noticed his own raging hard-on. He had completely ignored his own arousal, while he had been pleasing Cas, paying it no mind, but now his dick strained against the fabric of his boxers. He pressed his cock against Cas’ stomach to relieve a tiny bit of pressure, who smirked up into Dean’s face with a wicked expression before he let his hands disappear into Dean’s underwear.
Cas made Dean see stars, and Dean was sure, he couldn’t recall a time he had come that hard before. A thankful Cas was an even more enthusiastic Cas, and Dean, who laid in between crumpled, messy bed sheets, panting, feeling sweaty and sticky, Cas by his side, couldn’t remember ever being more happy than he was now. Cas had been making himself his very own place in Dean’s life.
He pressed a sloppy kiss to Cas’ sweaty hairline and pulled him even closer. “Mine” he whispered, “Mine”.
