Cas' mouth twitched microscopically. The fact that Dean was so calm and familiar with him was a good sign. The old Dean would have shot him by now. Never one for unnecessary chitchat, Cas stated his business.

"I want to fuck you, Dean."

At the words, Dean's sleepy movements halted abruptly and he slowly looked right at Cas. The angel studied his eyes; it wasn't just an adage that they were windows to the soul. Why do you think demons' are black? Dean was looking at him with slight confusion, but also with respect and trust, and most importantly subservience. Cas strode towards the hunter, whispering his desire.

"I want you to take off all your clothes and get on your hands and knees on the bed. Your legs will be spread."

Cas watched Dean strip, feeling very self-satisfied. He didn't need to go this far with Dean right now but he wanted to. So badly. More importantly, Dean needed it. Cas had already demonstrated dominion over his mind; his body was the next logical step.

Cas let his eyes rake over every tanned muscle on Dean Winchester's body as it was revealed. If not for his litany of scars, Dean would look like a statue of a Greek god, strong and perfect. But as a warrior himself, Cas found beauty in the scars scattered on his hunter's body. They told the story of his life, his battles, his victories; they told the story of a life that now belonged to Castiel.

When Dean positioned himself on the bed, Cas felt himself harden instantly. The sight of that perfect, perky ass pushed into the air, waiting for him…it was the ultimate aphrodisiac. Cas unbuckled his belt and pulled down his pants before getting onto the bed behind Dean. His belt in hand, he looped it around Dean's neck loosely, holding the ends in one hand on Dean's back. With his other hand, he guided himself into Dean's entrance with agonising gradualness.

He felt the quivering of Dean's entire body as he reacted to the intrusion. The grunts and whimpers of pain stealing past the hunter's lips only served to make it harder for Cas not to take Dean hard and fast right then. He knew Dean was in pain. He had neither stretched him nor used lube but this too was necessary. Dean had to realise and accept who he belonged to and that Castiel had the right to do whatever he wanted to him, however he felt like. He also wanted Dean to feel every excruciating inch of him inside, penetrating and claiming him.

When Cas finally bottomed out, he released a moan and licked his lips. So long had he wanted to be with Dean in this way, the two of them joined as one. He tightened the belt around Dean's neck, jerking his head back roughly. Cas lowered his head to Dean's ear and whispered.

"You will not enjoy this. Do you deny me?"

"No," exhaled Dean.

"Why?" asked Cas, testing the waters.

"I belong to you, Castiel. Your will is my command. I do not deny you," answered Dean in a vacant voice.

That was it for Cas. He pushed Dean down, making him lie flat on the mattress, with Cas still inside him. He pulled halfway out, then slammed back in, watching Dean reflexively jerk away from the pain with every stroke. He set a brisk pace, guiding himself in with one hand on Dean's hip. Cas let his head loll back and shut his eyes, focusing on the feeling alone. Dean's tight heat was his Utopia, the sensation of being milked and welcomed in by his hunter was almost too much. Cas let go of the belt around Dean's neck and pressed that hand to Dean's stomach as he thrusted. When he applied pressure, he could feel himself moving in and out of Dean's body. Castiel was not only possessing Dean, he could feel himself doing so.

The thought sent the angel into a frenzy. His strokes became supernaturally fast but more smooth as Dean had torn and his blood was lubricating Cas' passage. Laying himself completely on top of Dean, Cas fuck and fucked and fucked, the sheets brushing his hips when he pressed Dean down into the mattress. Cas could feel himself coming undone and surrendered to it. He bit down hard on Dean's shoulder as his ecstasy overtook him. His hot come emptied into Dean in long spurts, even as he was coming down off his high.

Cas raised his head to look at the Righteous Man. He didn't look so righteous right then for sure. Sweat poured off of him as he tried to re-regulate his breathing. His lips were slightly parted and his eyes sex-blown and glassy. Cas looked down at the bloody mess he had made of Dean's ass. Smirking cockily at the sight, he pulled out of Dean reluctantly and healed the rips he had caused. He didn't clean up the blood or take the pain away just yet. He liked the thought of Dean bloody and vulnerable for him.

Cas planted butterfly kisses on Dean's back and moved up his neck and cheek to his hairline. There he murmured

"You will not tell Sam or another soul about this. You are to act as normal."

Dean inclined his head against the bed. Placing his hand exactly into the mark he had made when he pulled Dean out of Hell, he relaxed against his hunter once more.

"Sleep, Dean."

The older Winchester instantly closed his eyes. As an angel, Castiel didn't sleep but lay there with Dean until morning. Then he arose, and put Dean and the bed back in the state he had found them. He left him there. He had to deal with Metatron and he was sure Sam and Dean were still hunting Gadreel.

Without changing anything else, he had planted in Dean's brain that he belonged to him, that Castiel was his main priority, before himself or even Sam. So it didn't matter where he went or how long he was gone, Dean would always be his now.

FIN

Author's Note: THIS IS THE END I SWEAR. It was supposed to be a one-shot but people made me feel guilty and that it was unresolved. A reviewer accused me of not liking Cas. Truth is, I love Cas. I'm just a perv ;)
