Dean's nose wrinkled. The sun had rose high enough to filter in through the new dark brown curtains hanging limp in front of the window. Castiel, who was rarely awake before Dean, took the opportunity to stare at Dean's face adoringly before planting a soft kiss on the cheek closest to him. Dean jerked awake, instinctively reaching for the gun under his pillow. Finger on the trigger still hidden under the pillow he rolled over, alarm seeping out of him as he realised it was Cas who had woken him and not some creature of the night. Cas frowned slightly as Dean's eyes swept the room quickly before releasing his gun and snuggling into Cas' warm body.

"I'm sorry" Cas whispered.

"It's all good Cas, you can wake me any day." A lazy smile reached Dean's face before stretching his neck up to kiss Cas lightly. Moving down to press his lips tenderly to the skin of Cas' neck, his morning hard on wanted more. Dean ran his fingers down Castiel's naked chest, a small gasp escaping from his mouth told Dean that he wanted more too.

They shared a moment of just staring into each other's eyes before their mouths collided together and it became an affair of lips, tongue and teeth. Five minutes went by before Dean pulled back to grin deviously at Cas, going straight for Cas' right ear, flicking his tongue over the lobe and then sucking it in long, greedy pulls. Dean got the reaction he was hoping for, Castiel's hips grinding up into Dean's, causing Dean to groan pleasure into Cas' ear. Dean could feel both their cocks hardening further; no one has ever made Dean as hard or turned on in his life as Cas does. He was reluctant at first to admit his feelings for Castiel but soon overcame his fears and opened up to the brilliant advantages of liking cock.

Dean was in the process of licking around the dark circle of one of Cas' nipples while pulling his underwear down when the bedroom door burst open...

"Dean, I – Oh! Ewwww!" Sam bolted from the room, leaving Dean to grumble about little brothers always interrupting and Cas to lay underneath him breathlessly. Dean gave Cas a small kiss before reluctantly moving off him and sat upright against the wooden headboard, Cas rested his head against the inner thigh of Dean's right leg, fingers tracing circles into the other thigh.

Dean, trying to gain some self control, yelled "SAM!"

Sam re-entered the room a little more cautious this time.

"Dude! Lucky we weren't fucking...yet." Dean gave a mischievous grin and winked at Sam.

"Gross." Said Sam, a little disgusted at how openly his brother talked about his sex life.

"So what do you want, Sammy?" Dean asked more seriously.

"Are you and Cas still coming to see Bobby this morning?" Sam asked by way of reply.

"Yeah, of course." Answered Dean.

Sam turned towards the door "Well stop 'almost' fucking and get ready. We've gotta leave soon." He walked out shutting the door behind him.

Dean felt pressure against his stomach. He looked down to see Cas staring up at him.

"What the fuck was his problem?"

"Perhaps he is jealous of our relationship, Dean."

"Really? You think so?" Dean asked seriously.

"Yes, Dean, we have each other but Sam has no one, the only other person Sam is close to is Bobby, but I doubt Bobby would be interested in a relationship with Sam."

Dean had a mental image of Sam and Bobby lying in bed together like him and Cas. "Cas you're ruining what's left of my hard on."

Cas gave him a small smirk, his human needs and emotions plus the things he had learnt from Dean showing on his face. Dean knew that look. He leaned his head back against the headboard as Cas placed kisses around Dean's belly button, licking at the thin trail of hair leading into Dean's boxers. It didn't take long for Dean to re-pitch a tent in his boxers, Castiel's lips moving against the tip until the fabric became wet and Dean was groaning for him.

Cas moved up and kissed Dean fast and rough while slipping his fingers in the waistband of Dean's boxers and pulling them off, leaving him naked and natural.

"Dean," Cas said, softly but firmly "I want you to watch."

Dean just nodded fast and wide eyed, maintaining eye contact with Cas. Castiel slid his hand up Dean's thigh to cup his balls, gently squeezing them, thumb rubbing lightly over one.

Dean choked out, "Cas," and that one word was full of desire and need.

Cas brought his hand up to the tip of Dean's cock, softly rubbing circles into the slit and spreading the pre-cum. Then suddenly Cas's mouth was pushing down over Dean's cock and he almost screamed in pleasure.

"Oh, fuck, Cas!"

Dean tried to watch as Castiel had asked but his eyes rolled back and pleasure won out as Cas put his lips right to the base of his throbbing shaft. Cas worked Dean's cock slow and steady at first but Dean begged him to go faster. Castiel obliged, picking up speed, humming as he did so. Dean was so gone that he barely mustered the energy to tell Cas, in a voice wrecked by pleasure, that he was about to come. Breathy moaning turned into a broken scream as he came hard and fast, Cas sucking him through the orgasm.

When Dean was done, he slid down the bed, completely gone. Cas cleaned them up, moving up to kiss Dean, Dean barely able to kiss him back. Cas laughed light heartedly and Dean grabbed his arms, pulling Cas on top of him, holding him tight.

Finally opening his eyes, Dean smiled at Cas, just staring for a moment before saying, "I love you, Cas, you know that, right?"

"I know, Dean. I love you, too"
