"Cas, what's your idea of heaven?" Dean asked.

Cas smiled to himself, "Each soul generates its own Paradise. I favor the eternal Tuesday afternoon of an autistic man who died in a bathtub in 1953."

Dean cocked an eyebrow, "That's... specific?"

Castiel pressed two fingers to Dean's forehead and suddenly they were inside the heaven Cas talked about, projecting it like a movie, but minus the autistic man. Castiel laid down in the warm grass and Dean joined him. This is where Cas would go to get away from his worries... before he fell.

They intertwined their hands and Dean closed his eyes, "I think I like this eternal Tuesday afternoon," he whispered.

Castiel stared at Dean, studying him carefully. He felt as if he was falling in love with humanity.

And most of all, Dean Winchester.

Cas couldn't stop himself from asking, "Remember when you asked me if I have ever been in love?"

Dean opened one eye to look at him, "Yeah, why?"

Castiel stared into Dean's eyes, getting lost in the fading green. Castiel admitted, "I can finally say I have been in love."

Dean stared at him; slightly confused, or afraid to assume the best.

"I am in love with you, Dean," Castiel revealed.

Dean's mouth tugged into a smile, "I'm in love with you, Castiel."

Dean leaned over, his fingertips grazing Castiel's forehead as he moved a few stray hairs. His fingers trailed to the back of Castiel's neck and he lightly pulled Cas' head close to his own. Their foreheads bumped and breaths hitched. Cas held Dean's waist and their lips gently connected; opening and closing against each other. Dean nibbled on Cas' bottom lip. He pulled away, "I want you, Cas."

Castiel smiled, "I want you too, Dean."

Dean shook his head, "No, I mean sexually."

A simple "Oh," escaped Cas' lips. He looked confused, "I forgot there was more to human intimacy than just this."

Dean rolled on top of Castiel and sat on his torso, making an effort not to apply too much of his weight on him. He tugged off Cas' trench coat and unbuttoned his shirt, tossing both articles into a pile beside them. Dean pulled his own shirt over his head and added on to the mound of clothes. He leaned down and kissed Cas sloppily as he grinded against him in attempt to form Cas' first hard on.

When he could feel the bulge forming, he sat up and carefully slid off Cas' dress pants and boxer briefs, then did the same to himself, throwing them onto the pile like everything else. He hovered over Cas with nothing on but the amulet his brother gave him dangling from its string. He pressed his body against Cas and kissed his neck, sucking and biting lightly on the area to leave his mark. He licked over the blemish before nibbling again. Cas let out a moan, feeling something he had never felt before.

Dean smiled against his skin and chuckled a little, Cas felt the huff of laughter tickle his neck. Dean reached over to the pile and pulled a travel-sized lubricant out of his pocket.

Cas looked at it with his eyebrows furrowed, "What is that?"

Dean smirked, "Something to help me get in easier."

Cas opened his mouth, still confused and filled with questions, but Dean shushed him, "Just trust me, you want me to use this."

He unscrewed the top and poured the liquid into his palm. He then rubbed his hands together and lathering it onto his cock. Cas watched him in curiosity, getting turned on unintentionally.

Dean realized Cas had no idea what to do or what was going on. He lifted up Cas' thighs for better access, "You gotta work with me, darling," he whispered.

Castiel nodded as Dean pushed into him for the first time. Cas' eyes widened and he gasped as he stared up at the blue sky, his hips bucking upward. Dean pulled out a little and then thrusted back in.

A moan escaped Cas' mouth. He stared up at Dean, absorbing both the shock and ecstasy of their two figures combining. The sensation of just feeling Dean was amazing. Dean pulled out again and pushed back in to reach up and kiss his lips. His breathing hitched, "Are you okay, Cas?"

Castiel nodded eagerly, "Could you please go faster?"

Dean grinned and did as he requested, increasing his speed. They kissed sloppily between each thrust, greedily taking each other in. Dean began pumping Cas' cock in unison to his thrusting, and Castiel gasped - somewhere between a moan and a grunt - at each pump and push. The pleasure was overwhelming. The movements became faster by each passing second, each kiss messier than the last.

And then they both came.

Cas couldn't believe what he was experiencing. The sensation was incredible. Dean was incredible. Everything about him was stunning. Exhilaration was the only thing Cas felt in that moment.

Dean pulled out and rolled over onto his back, both lovers breathing heavily. Dean caressed him in his arms as Cas leaned his head on Dean's chest, the two sitting in an awed silence.

"So how was it, Cas?" Dean asked finally.

"Humanly indescribable," Castiel breathed.
