Chapter Twenty-One

Cas had been at the Winchester residence for a week and he loved every minute. He finally felt like part of a family, John and Mary were nothing short of amazing to him, treating him like their own and Sam was treating him as an older brother…but maybe with slightly more respect for Cas, than he had for Dean.

Sam was still unaware of Cas and Dean's relationship and as far as Sam knows Cas had a family row but wasn't sure what about. Mary and John didn't really mention it in depth, but Mary had made it very clear that there was to be no "funny business" under her roof.

Castiel had been given the box room of the house, John and Dean had cleared it out and made it more liveable for Cas to sleep in there. He enjoyed having his own room, but would prefer to be with Dean and most nights he was, sneaking back into his boyfriend's room to lay with him. Of course so far they had followed Mary's rule of no funny business, but it was getting more difficult by the day.

Weirdly school had been much better for Cas and Dean this past week. As expected there was a lot of whispers and a couple of sly comments, but other than that people left them the hell alone…just the way they wanted it.

Cas had been coping alright since his argument with Zachariah, having such a loving family environment at the Winchester house was definitely a help.

Another weekend was fast approaching and Dean always looked forward to them, now more than ever.

Dean and Cas sat up on Dean's bed, resting their backs against the headboard as they talked.

"I think we should tell Sam…"

Dean nodded silently in agreement at Cas' statement.

"Yeah I've been thinking the same thing…I feel bad keeping this from him, he is my little brother after all…I don't actually know why I haven't yet…guess its some sort of scaredy cat big bro kind of thing." Dean chuckled.

"He deserves to know…I don't like keeping it from him either." Cas said, turning to smile at Dean.

"Agreed and we will…but right now, I'm more interested in you." Dean said with a glint forming in his eyes, smirking at Cas and running his hand up Cas' arm slowly.

Castiel's breath hitched slightly at Dean's movement and shuffled on the bed to turn more towards him.

Dean slowly leant in, capturing Castiel's lips in a soft kiss, running his hand over Cas' still clothed stomach and reaching a strong arm around him, pulling him closer.

Cas hummed in pleasure against Dean's mouth and smiled against the kiss. He ran his hand up Dean's side, letting his fingertips dig in slightly and forming a slight, teasing pressure and deepened their kiss, letting tongues slide against each other.

Running his hand down Dean's back, Cas couldn't help but drag it further down and grabbed Dean's firm ass, digging his fingers into the clothed skin and rolling onto his back, pulling Dean on top of him.

"Jeeez Cas…eager much?" Dean chuckled, before kissing at the stubbled jaw line in front of him, earning a moan from his boyfriend below him.

It's true…Cas was eager…very eager. He was more than ready for him and Dean to go the whole way, but was scared to express it and also figured Dean would be just as scared.

They had done "stuff" as Dean liked to put it, mostly from prompting by Cas who started off the instigator and usually led to Dean taking the upper hand and doing stuff to him. Not that Castiel minded…Dean always made him feel amazing, but Cas hadn't gotten much chance to do very many things to or for Dean in return and he wanted to….so badly.

Dean kissed away at Cas' neck, sucking forcefully at the soft skin and leaving little red marks. Cas' short fingernails dug deep in Dean's back as encouragement and lifted both of his legs, spreading them apart to let Dean slide in between them.

It was very rare that the boys lost much clothing during their little encounters, which also frustrated Cas and yet he still managed to get incredibly turned on even when fully clothed. Dean just did things to him.

Speaking of which, Dean was now grinding his hips against Castiel's and it felt incredible, the way he moved his hips was nothing short of awesome and the pressure applied was just enough to get them both ready for more.

"Ohh god Dean…but…we shouldn't…what about your Mom?"

Dean stopped his movements and brought his head up to look at Cas with a half disgusted, half curious face.

"You wanna talk about my mom…now?"

"What? No no…I didn't mean in that…I thought we promised her, no funny business?"

"We did…but they're not in right now and what they don't know…" Dean said smirking and teasingly pushing his hips down against Cas.

"…Won't hurt them."

Cas groaned and swallowed hard, before nodding rapidly.

Before Dean could restart his movements, Cas put a firm hand against Dean's chest and pushed him back, much to Dean's confusion.

"No."

"What do you mean no?" Dean said in shock, shaking his head in disbelief.

"We do this…on my terms Dean." Cas said firmly, the low gravely tone of his voice instantly did things to Dean's body.

Cas continued to push Dean off and roll them over, so he was now on top and in total control. He forced Dean's legs apart, letting himself slide between them and get comfortable, mirroring the position they had just moved from, only it was now him above Dean and he loved it.

Slowly he started kissing and sucking away at Dean's neck, his hands found Dean's hips and he dug his fingers in roughly and pushed hard against Dean.

"Jesus Christ Cas!" Dean moaned. As hot waves of pleasure shot through him.

Cas was not nearly as innocent as everyone thought, he may be a virgin but he knows how to tease and play the game well…which was strange to Dean, given his lack of experience.

Not wasting much time, Cas decided the fully clothed act was getting old and practically ripped Dean's shirt open, revealing his toned and muscular body, much to Cas' delight. His mouth instantly met with Dean's skin, licking and kissing his way down Dean's body.

"Mmmm Cas…don't stop please…" Dean moaned and ran his fingers through Castiel's hair, guiding him further down his body. Dean liked were this was going and if truth be told…he had wanted Cas to do this for a long time.

Castiel looked up at Dean, his head now hovering by the waistband of his jeans and he winked at his boyfriend before slowly removing Dean's belt…

"Dean…you in here…I need to borrow…."

The sound of Sam's voice came too fast for them to do anything about it. Sam strolled into Dean's room not bothering to knock and Dean's head instantly shot to look up.

"…OH MY…OH MY GOD…MY EYES…" Sam yelled, almost too loudly and quickly ran out of Dean's room.

Cas' head was trying to register what just happened, shooting a shocked glance between the door and Dean.

"Oh well…at least we don't have to go through the trouble of telling him about us." Dean chuckled, but he was inwardly cursing at his brother's extremely bad timing.

"Dean…that isn't funny!" Cas exclaimed, lightly punching Dean.

Begrudgingly Cas jumped off Dean and headed for the door concerned for Sam.

Dean shook his head and started doing his shirt up, muttering under his breath and slowly following Cas out of the door.

"Why with the fucking interruptions, all the fucking time. Stupid Sam…stupid, stupid, stupid…"

O-O-O-O-O-O-O

Sam was now pacing up and down the living room at a rapid pace, when Cas entered.

"Hey Sam…Are you…ok?"

The look of horror that Sam threw him, Cas knew it was a stupid question and he snapped his mouth shut.

Dean strolled in and shot Cas a flirtatious smirk and a wink.

"Not now Dean…" Cas muttered quietly and nodded towards a concerned looking Sam.

"Right…ummm Sammy?"

"What the heck did I just walk in on dudes? That was…you guys were…what the hell?" Sam stuttered through his words, trying to make sense of what he had just seen.

"Look I'm sorry, this wasn't how we wanted you to find out…really…"

"Find out what Dean?" Sam stopped pacing and looked straight at his brother, his face a little flushed and embarrassed.

Dean and Cas shared a look of understanding and Dean started to explain to his little brother.

"Me and Cas…we are together, you know like…in a relationship, together."

Sam just gaped at his brother.

"But…you like girls Dean? You're not gay!"

"Maybe I am, maybe I'm not…maybe I'm just gay for Cas, whatever…it doesn't matter. We figured out we wanna be more than friends…so there…build a bridge and get the hell over it Sam."

Sam looked wide eyed at the pair, especially at Dean.

"No need to be so…forceful Dean, it's a lot for him to take in." Cas stated, giving Dean a hard glare.

Rolling his eyes at Cas, Dean took a deep breath and stepped towards Sam.

"Look…I'm sorry OK…that is not how we wanted you to find out about us…we were waiting for the right time. I just hope you can…accept it?"

Relaxing his stance a little, Sam let out a small sigh and gave them both a shy smile.

"Dean…I may be a kid, but I'm not stupid, naïve or narrow minded…If you guys are happy, then why the heck not be together, right?. I was just a little…shocked."

Dean breathed a huge sigh of relief and smiled at his brother, punching him lightly on the arm.

"Yeah…sorry about that…but thanks Sammy, knew I could count on you to deal with this in a grown up kind of way…You're like 13 going on 30." Dean chuckled.

All three of them felt the air fill with a positive atmosphere, Cas still completely in awe of how the whole of Dean's family have been so good about their situation…even his little kid brother.

"Thank you Sam."

O-O-O-O-O-O-O-O-O

Dean and Cas finally returned upstairs, after a long in depth conversation with Sam and then some bribing on Dean's part, promising that he would do Sam's chores for a month if he didn't tell his mom what he caught Dean and Cas doing…or about to do.

Cas sat down on the end of Dean's bed and Dean flopped down next to him, letting out a long, frustrated sigh.

"I'm glad he knows…" Cas started.

"Me too…but he couldn't have knocked? I'm sick of being interrupted" Dean sighed out, the frustration and anger clear in his voice.

Cas placed a hand on Dean's knee and searched to meet his boyfriend's eyes.

"I know…believe me, I'm frustrated too…finally on my way to sucking you off for the first time and your brother walks in…not cool"

Dean couldn't help but laugh out loud at Cas' choice of words. Clearly Dean's behaviour and actions were rubbing off on Cas, the more time they spent together.

"Not cool at all…and we will get there…if it's the last freakin thing I do." Dean chuckled.

They both heard Sam's voice yell from downstairs.

"Ummm GUYS….I'M GOING ROUND TO JESS' HOUSE…I'LL BE ABOUT AN HOUR. COULD YOU LET MOM AND DAD KNOW WHEN THEY GET IN, DEAN?"

Dean rolled his eyes and laughed.

"YEAH YEAH, I'LL TELL EM." He yelled back.

Suddenly realisation hitting Dean and Cas that they were now alone…for real this time.

"Hey Dean…you know you said, we would get there?"

Dean nodded dumbly, knowing where this was headed…or at least he hoped so this time round.

"Would now…be a good time…to get there?" Cas said nervously.

"Yeah…it definitely would." Dean grinned, seductively and pulled Cas to lie on top of him once more, allowing their bodies to melt together.

Cas' heart was beating incredibly fast, he felt like he had lost his confidence and returned inside his shell…but he was determined to do this.

Dean helped things along, by removing his shirt and taking off his belt in urgency. Cas watched, licking his lips at the sight of Dean undressing below him.

Before he could unbutton his jeans, Cas held out his hand to stop him and pushed Dean's aside and used his own shaking hand to unzip the jeans.

Cas slowly pushed his hands inside the waistband, letting his fingers apply pressure and sweep across Dean's hips slowly and torturously.

"Please Cas…wan't you…now." Dean was practically at a begging stage, he had been waiting too long for this.

Cas nodded, a small smirk now forming on his face once again and he pushed the jeans all the way off Dean. Gripping his hips forcefully, Cas latched on, kissing up Dean's inner thigh and working his way up.

He hovered above Dean's still covered, now hard cock and took the bulge into his mouth, sucking Dean through his boxer shorts.

"Oh fuck…Cas!" Dean yelled out, not expecting the sudden assault.

He wanted to feel Dean so badly…wanted Dean in his mouth and he couldn't wait any longer. Cas practically ripped off Dean's underwear, only to be greeted with the sight he had been longing for this whole time. Dean's now fully hard cock was begging to be touched…and Cas obliged.

Castiel carefully reached out with his hand, gripping Dean at the base and sliding his tongue over the tip experimentally, hearing an audible gasp and moan from Dean.

He pulled back and looked up at his boyfriend, a curious look in his eye.

"Dean…I don't know what I'm doing here…"

"You have barely touched me and I already feel like I'm gonna come. So trust me…you're doing great, just don't stop…I want your mouth on me…please Cas…experiment…try stuff…I don't mind…just go for it…I need you."

Dean's begging was music to Cas' ears, he loved being the one in control and the sudden urge to feel power took him over and he just went for it.

Suddenly Cas' mouth was on him furiously, his hand gripped the base of Dean's cock and Cas' mouth enveloped Dean and took him all the way in.

"Holy shit Cas…" Dean moaned out loudly, the sudden impact of Cas taking him all the way in, nearly sent him over the edge.

Cas' tongue slid along the sensitive underside of Dean's length, while his mouth sucked hard and slid back and forth, creating a steady rhythm. The sensations drove Cas wild, he enjoyed this far too much and his own hard on was painful. Not being able to take it anymore, Cas started moving his body in time with his mouth, creating friction between his own crotch and the solid bed, trying to get himself off in the process.

A long moan erupted from Cas' throat, creating vibrations around Dean's cock as Cas continued to suck.

Dean threw his head back against the pillow in ecstasy and pushed his fingers through Castiel's hair and bucked his hips up, pushing further into Cas' mouth.

He almost gagged as Dean pushed against him, but obliged by moving his mouth faster up and down Dean's length, using his tongue to create more sensations and taking Dean as far in as he could manage. The consistent moans and cries told Cas he was definitely doing the right thing.

Cas pushed his own hips more forcefully and at a faster pace against the bed, his own orgasm causing him to shiver and moan with Dean still in his mouth and that was the final straw for his boyfriend.

Dean followed Cas' orgasm, his own racing through his body like an electric shock and jolting him off the bed as he fucked Cas' mouth, riding out the after math. Cas did his best to swallow down every last bit of Dean, the taste was not very pleasant but it was all Dean and that was good enough for Cas.

Finally they parted, completely exhausted and panting for air. Cas pulled himself up and lay beside Dean.

Dean turned his head to Cas, giving him a lazy smile and leant in for a soft kiss.

"That was…freakin awesome." Dean chuckled.

Cas hummed in agreement, a bright smile plastering his face and not looking to leave anytime soon.

Dean looked at Cas with adoration, he loved seeing him smile…it was so warm and genuine, he just wanted Cas to be happy. He slowly took Castiel's hand into his own and entwined their fingers. Dean had nothing but love for Cas and he was starting to realise this.

"I love you…you know that." Dean said smiling.

*Wow* he thought, never thinking the words would come so easily to him and so soon.

But this wasn't a short term relationship, he decided they were in it for the long haul…it wasn't too soon to love Cas, because he guessed on some level…he always has.

Cas looked taken back for a moment, before leaning in pressing a firm kiss to Dean's lips and pulling back with a content smile.

"I love you too, Dean."
