Castiel slowly opened his eyes and sat up, blinking and looking around slowly, substantiating his place and time. His head tilted slightly to one side and a small smile lit his face upon hearing the familiar music.
"Cas!" Sam exclaimed, "you're back!" Sam's face lit up, but then dimmed when he noticed his brother, while no longer groaning, remained asleep. "Cas… is he… gonna be alright?" Sam asked, biting his lower lip pensively.
"Yes, Sam, I believe he will be," said the angel, slyly.
Is he smirking? thought Sam. "Why is he still asleep?"
"This was a much more peaceful transition than we had experienced previously. I did not need to… forcibly eject him this time." Castiel met Sam's eyes with a measured gaze. "Sam, it is possible that Dean might not remember what happened. He may wake confused or disoriented."
"Cas, what happened in there?" asked Sam with concern. It was then that Dean's eyes fluttered open. He lifted his head slightly, full lips gently parted as he looked at his brother and blinked as if the verify his corporeality.
"Cas?" he muttered languidly.
"I am here, Dean," the angel replied warmly, with a small smile and luminous blue eyes that were all Dean's.
Dean blinked again, and then without warning he shot out from the bed straight at Castiel, gripping the arms of the rolling desk chair and smashing it into the desk three feet behind them. He wrapped his arms around the back of Castiel's neck and up through his hair. He kissed his friend with a newfound passion, feeling his warm, soft lips for the first time. Castiel sat stiffly at first, overcome with emotions he had never needed to process before. But then, Dean opened his mouth and Castiel could feel his warm tongue caressing his lips, searching for an opening. Castiel was undone. Their arms flailed for purchase, and with mouths still locked they pulled themselves to standing. Castiel reached his arms around his friend, one hand slipping under the back of Dean's shirt and the other squeezing him closer, tighter. He wanted to feel the heat of Dean on his skin, wanted his smell all over him. He opened his mouth to mirror Dean's, tongues darting in and out, exploring one another on this great new expedition.
Dean felt weak in the knees, barely able to bear the strain as his heart flooded with gratitude and his mind clouded with lust. He had no more misgivings, no more doubts. He knew what he wanted, what he had always wanted, and now he was going to take it, dammit. He pulled his mouth away from Cas' and heard his angel sigh piteously, a noise that shot through every neuron in his body and triggered a stiffening in his jeans that ached for Castiel. He dove his face into the angel's neck and began kissing his collarbone delicately, methodically, resisting the urge to devour his friend whole. There was Cas, and only Cas, and nothing else.
"Ahem," Sam cleared his throat. "Guys…?"
