Dean woke the next morning, his head lying on Cas' chest. He brushed Cas' neck with the top of his head, smiling as the blue eyed man's eyes fluttered open.
"Mornin'..."
Dean whispered before nipping at Cas' neck.
"Good morning, Dean."
Cas replied in a low, husky voice- it was more gravelly than usual. Dean liked that.
"Breakfast?"
Dean asked, Cas looked into Dean's eyes before grinning slightly.
"No, let's just stay here for a while."
Dean nodded before wrapping his arms around Cas, the two lay their blissfully, and soon fell asleep in each other's arms.
After a few hours, they were interrupted by a knocking at the door.
"Cassie? You in here?"
The couple woke with a start.
"Why the hell is Gabe here?"
Dean asked, giving Cas a furious look.
"I told him I was at yours so he wouldn't disturb us, I don't know why he came."
Dean sighed before scrambling into his underwear and jeans from the night before- he would find his shirt later- and answered the door.
His eyes widened as it wasn't just Gabe standing there. Sammy was there too, looking at him with a horrified expression.
"Dean?!"
"Sammy...what are you doing here?"
"Well, I wanted to pay you a visit, and when I got there, Gabriel was at your door, saying something about Cassie and his boyfriend Dean, which I thought would be impossible because you're not gay- I came with him to help him find his brother...and here we are..."
Dean slapped a palm to his face.
"Sammy, I'm not gay, I'm just-"
The trio looked up in surprise as a half naked Cas stumbled out of the bedroom, wearing nothing but his black boxers and Dean's shirt from the night before.
Dean rolled his eyes.
"I'm bisexual."
Sam's mouth formed an 'O' before laughing and then playfully punching Dean in the arm.
"Why didn't you tell me?"
"I don't know Sammy, I didn't know what you might think- dad certainly didn't approve and I wasn't sure-"
"-Dean I'm gay!"
"Oh."
The brothers laughed before pulling each other into a hug.
"Jerk."
"Bitch."
"Ahem."
The shorter Novak brother interrupted.
"So you're screwing my brother?"
Dean's eyes widened.
"Well, it's a little more than that."
He looked over at Cas and the pair blushed, looking away sheepishly.
"Okay...guess we'll just leave you guys to it."
Gabe looked over at Sam, raising his eyebrows suggestively.
"Hey, Sam, do you wanna grab a coffee or something?"
Sam smiled. Before looking nervously over at Dean; who was giving Gabe the evil eye. If looks could kill, Gabe would be dead as a door nail. Sam chuckled to himself.
"What the hell- sure!"
Sam replied. Gabe flashed him a mischievous grin, before leaving the apartment.
Dean frowned.
"Sammy's a baby- tell your brother to back off."
"Sam is an adult, Dean, he's perfectly capable of making his own decisions."
Dean sighed.
"Yeah, well that doesn't mean I have to like it."
Cas smiled before watching Dean run to the bathroom.
"Dibs on the shower."
He called out. Cas smirked as he heard the water start running. Dean had left the bathroom door unlocked. Cas slipped in quietly, grinning at Dean's terrible singing to some old rock song. He removed the sparse amount of clothing he had on and climbed into the shower, causing Dean to jump out of his skin.
"Dammit Cas- don't do that!"
Cas silenced him by pressing a kiss to his lips, Dean melted into the kiss. Soon Cas kissed him harder, pressing Dean against the wall, allowing the hot water to trickle down his back. Cas could feel his erection throbbing, he turned them around.
Dean could see that look in Cas' eyes, his eyebrows raised dominantly, he licked his lips as he stared at Dean.
"What do you want me to do...?"
Dean teased, flashing Cas a playful grin.
"Get on your knees..."
Cas growled in a low, husky voice.
Dean was face to face with Cas' erection, he felt Cas' hands on his head, leading it forward. Cas moaned as he felt Dean's mouth around his skin, his hands still on his head.
"Oh..."
Cas moaned, as he felt Dean's tongue around him, he guided Dean so that his tongue travelled further and further, as Cas thrusted harder into his mouth.
"Oh...god...mmm..."
Cas grew louder and louder as Dean's mouth travelled further.
He pushed further, causing Dean to take in his full length. He groaned as he felt himself hit the back of Dean's throat, and Dean hummed slightly as he did so.
"Ohhh...Dean..."
Cas moaned; at this, Dean pulled away.
"You said my name?"
Cas rolled his eyes- couldn't they talk after the blowjob?
"Yes."
"I thought you were the dominant one."
"Just because I'm the dominant one, doesn't mean you can't sexually please me."
Dean smirked before resuming, he took Cas' full length into his mouth again, grabbing onto Cas' hips, goading him to thrust harder. Cas regained control of the situation, as he removed Dean's arms from his hips, manoeuvring them so that he had Dean pinned against the wall.
Dean pulled away as Cas held his hands above his head.
"Keep your hands there."
Cas said, before cushioning the back of Dean's head as he thrusted deeper and deeper into his mouth, hitting the back of his throat over and over again, causing him to moan louder and louder.
"Oh...fuck...Dean..."
Cas could feel everything building, he was close.
"I'm so...I'm so close..."
Cas groaned, he came with a final "OHHHH...GOD...DEAN!"
He held Dean's head, grabbing fistfuls of Dean's hair as he continued to suck and swallow. Dean finally pulled away, the goddamn boyish, smug, self satisfied grin that Cas loved was plastered on his face.
"Was that good?"
Dean asked, almost innocently- he knew it was.
"Good...doesn't even...describe it..."
Cas panted.
Dean pressed a soft kiss to Cas' lips.
"Okay, I'll leave you to...clean up- maybe get some cold water running; and I'll get dressed and start on some post-sex breakfast."
Dean smiled as he left the bathroom. Cas smirked; he was gonna make Dean scream.
