A/N: Alright here's the first chapter of this new idea that just kind of hit me while I was watching "The End" (Season 5 Episode 4). This is my first Dean/Cas fic, so sorry if the characters are a little off. Enjoy!

Future Surprise

Chapter One

"What happened to you?" Dean asked, perplexed, as he looked at the rumpled, unshaven Cas. It was like running into your stick-in-the-mud boss at a strip club. Unnatural.

"Life," Cas replied, giggling again and sitting on the bed with a thump. "Life happened, Dean. You of all people should understand that."

"So what, now you're having orgies and flying as high as a kite?" Dean asked, still trying to wrap his brain around this future Cas. "Man, when you decided to embrace your rebel status you pulled out all the stops, didn't you?"

"Oh yes," Cas said, looking at Dean intently. "Drugs, sex, booze, all the big sins. And let's not forget the sodomy." Dean froze.

"Come again?" he asked, shaking his head, sure that he could not have just heard what he thought he heard. "You want to repeat that for me, hippie boy?"

"You heard me," Cas laughed, flopping back on the bed and staring up at the ceiling, grinning. "I'm taking it up the ass! Or giving it, depending on the occasion, but that's only if I've been very, very good."

"So you're gay now?" Dean asked, trying to process this new and slightly disturbing piece of information.

"I believe the term is bisexual," Cas answered, propping his head up on one arm and looking at Dean, a small grin on his lips.

"Wow Cas… I'm glad you're so – um – open about it," Dean said, trying to keep his voice normal and not betray the swirl of confused emotions going on in his head.

"Don't you want to know who it is?" Cas asked, sitting up and looking at Dean with an expression that Dean couldn't read. It was a combination of smugness, excitement, and unease.

"Who who is?" Dead asked, not sure he was happy with where this conversation was heading.

"The guy," Cas replied, surveying Dean intently. "My lover. The one who helped me rebel even further against the mandate of the angels. The one who seduced me."

"Um, not really," Dean said, quickly looking away as heat crept up his neck. It took a lot to make Dean Winchester blush, but the thought of some anonymous guy putting his grimy hands all over Dean's Cas…

"Yes, you do," Cas said, his voice smug. He watched the blood creep up Dean's neck with satisfaction. Cas knew he had him. Dean would be drawn by his own morbid curiosity.

"Alright, since you're obviously dying to tell me, fine," Dean snapped, turning around, suddenly angry. His hazel eyes flashed and Cas felt his heart leap in his chest. "Go ahead, Cas. Tell me who finally popped your rectal cherry if it means so goddamn much to you!"

"You," Cas said, a small smile forming as he watched Dean rant. For the second time that night Dean froze, unable to comprehend what Cas had just said.

"Huh?" he asked, taking a step closer to Cas, his eyebrows furrowed in confusion. "What did you just say?"

"It was you, Dean," Cas repeated, grinning at the obviously baffled man. "You were the one who, as you so succinctly put it, 'popped my rectal cherry.' You were my first male lover, and you will always be my only male lover."

"Huh?" was all Dean could muster as a response. Cas rolled his eyes.

"Come on, Dean," he said getting up off of the bed in a surprisingly quick and fluid motion. "It's not that hard of a concept to understand."

The sudden invasion of his personal bubble jerked Dean out of the fog that he had been floating in. He came back to reality (well, this reality) with a thud. His mind was a raging chaos of muddled emotions. What was Cas talking about? Was he lying? Of maybe it was just all some elaborate trick that this more carefree Future Cas was playing on him. Yes, that had to be it.

"Oh, haha, very funny," Dean said, laughing and clapping Cas on the shoulder. "That was pretty good, Cas, you had me going there for a minute."

"This is not a joke, Dean," Cas said, and for a moment Dean could see his Cas, the Past Cas, peeking out of Future Cas' eyes. He felt a pang in his chest and realized that he missed his Cas. "It is the truth."

"So, let me get this straight," Dean said, still half convinced that Cas was pulling one over on him. "I, mister straight as an arrow woman lover, seduced you, the epitome of the Bible Camp. Right."

"Well actually," Cas said, shifting slightly closer to Dean. "It was more like I seduced you, if I'm to be completely honest. But you started it, what with those beautiful hazel eyes and fierce spirit. How could anyone not fall in love with you?"

"Cas, you're starting to freak me out here," Dean said, suddenly away of how close the other man was. His heart began to race and he swallowed, mouth suddenly dry.

"Am I?" Cas asked, leaning closer, eyes catching and holding Dean's. "Because if I didn't know better, I'd say you were getting excited."

"Hold on, just time out for a second, okay?" Dean asked, looking at Cas with pleading in his eyes. Cas smiled gently at him and nodded, take a step back. Dean took a deep breath and closed his eyes, trying to steady himself.

"Alright," he said finally, opening his eyes and looking at Cas. "What's the story with you and … Future Me, This Me, Now Me, however you want to say it? What's between you two and how did it go down?"

"It started after Sam," Cas said, all playfulness put aside as he sat down on the bed. "After Dean got word of what happened to him, I went to him. He was just sitting in his cabin staring at his drink. I knew it was bad when I saw that the glass was untouched. I went to him and told him I was sorry."

"What did he – I – we do?" Dean asked when Cas paused, almost scared of what the answer would be. Cas looked at him and smiled mournfully.

"He hit me," Cas said, the smile turning rueful as he remembered. "He hit me and then we fought. I knew it was what he needed. He needed to release all his anger and at that point I was still harder to hurt than most humans. After he had worn himself out I sat with him for the night. At first he tried to fight it, but at last he broke down and cried. I couldn't help myself. I had loved him, in one way or another, ever since I first met him. So I kissed him. And that night we made love."

"But… the women, the orgies, Jane, Resa… you guys aren't… together anymore?" Dean asked, forcing himself to go about this logically and not take time to mull on what Cas had just said.

"He doesn't want people to know," Cas said, shrugging his shoulders, face sad but resigned. "That's why the women and the orgies. He's ashamed of me, I guess. He doesn't come to me very often anymore. He's been getting colder and colder. He's withdrawing into himself. And when he does come, it's not gentle or loving. It's hard and fast and cold. Sometimes I feel like he's a stranger."

"Ashamed? That son of a bitch is ashamed of you? What a fucking dick!" Dean yelled, turning away, unable to bear the sorrowful look on Cas' face. "He has no right to treat you like trash or some convenient lay."

"Why?" Cas asked, watching the past version of his lover rage about the things his future self was doing. Cas missed that fire. His Dean, the Now Dean, had lost his flame. He was as cold as ice now.

"Because I – we – care about you!" Dean replied heatedly, refusing to look at Cas as he said it. It took all of his courage to speak those words, but he knew they had to be said.

"Maybe you do," Cas said gently, smiling at Dean, his eyes hollow. "But he doesn't. Not anymore."

"Yes, he does" Dean replied, turning and looking Cas full in the face. "He may not show it, but he does. I know myself and I know he cares. I just have to remind him of that fact."

"What do you mean?" Cas asked, suddenly wary. He knew that look in Dean's eyes. It was the look that came before he did something rash.

"I mean I think it's time Future Me and I had a talk," Dean said. The sound of a caravan of vehicles rolling down the drive filtered into the cabin. "I'll bet that's him right there."

"Dean," Cas said, quickly getting up and following Dean to the door. "Do not do anything rash."

"Would I do that?" Dean asked, shooting Cas a grin before he walked out the door. Cas groaned and hurried after him.

A/N: Well, there's the first chapter. There will be one more chapter and then a very short epilogue. I'm not sure if I'm happy with how this came out. Let me know what you think. Reviews always make my day.
