The thought is terrifying, isnt it? I took the risk of attempting a funny story. These will be rare, since I am an angst lover. But let me know if you'd like to see more like this!

Castiel had overheard Dean and Sam talking about slash, but he had no idea what it really meant. He'd wanted to ask about it, but never had the occasion. So he'd waited.

An now, on one of those quiet nights in a motel room, Sam doing research, Dean drinking a beer, reading the newspaper for a hunt.

"Dean." Castiel said cautiously.

"Yeah, Cas?" Dean asked distractedly.

"What is…'slash'?" he asked, cocking his head. Unfortunately for Dean, he'd had a mouth full of beer in his mouth, and he ended up choking to stop it from coming out of his mouth. Sam's mouth just dropped.

"You're kidding. You don't want to know." Dean said, wiping dribbles of liquid off his face.

"How bad is it?" Castiel frowned.

"Bad. Horrible."

"Really. Would you give me an example as to why?"

"No."

Sam raised an eyebrow. "Where did you even hear about slash?" he asked, closing his laptop.

Castiel shrugged. "I'd heard you talking about it."

Dean rubbed a hand through his hair. "Yeah, uh, it's….complicated."

"Dean, why don't we just tell him? What harm is it?" Sam asked.

"What harm? Lots of harm! You really want the angel world to know about…that? What we've read? It's pretty freaking harmful!"

Sam opened the laptop again, and Dean saw a glimpse of the Google homepage. He couldn't see what Sam was typing, and he really didn't want to know.

"Well, I hate to bear bad news, but since Chuck has started publishing again…." Sam didn't get to finish.

"WHOA. What? No no no no! Is he insane?" Dean exclaimed. Sam switched back to Google, and Dean's face turned into horror when he recognized the homepage. "Sam, no…"

"You're going to love this. Fans love Cas, and they've created…something related to…that." Sam said, eyes widening at the screen, but his face was an amused smile. "It's a war."

"STOP GRINNING. This is not funny." Dean yelled, slamming his head into the wall.

Castiel, who'd now been trying to maintain his patience, was tired of being completely ignored. "Would you two please tell me what you're talking about, since it involves me."

Sam looked ready to burst out laughing. "Cas…you remember Chuck? The prophet?"

Castiel nodded. "Of course."

"Sam, don't…the angels will use it against us, I swear! They'll tell demons and then we have to listen to those bitches going on and on about how two brother having sex together! I MEAN C'MON!" Dean's mouth snapped shut at his slip of words.

Castiel's eyes widened. "Dean, you have sex with your brother?"

"What? NO! The fans….fan girls…the Internet? Chuck writes the books and then the fans make up these disturbing fake stories of our lives."

"Oh." There was a pause. "In this Internet world….are we together too?"

Sam could not contain his laughter and fell on the floor, clutching his stomach. "Oh God…"

"In some sick minds. Don't get any ideas."

"So what's slash exactly?" Castiel asked again.

"It's where two guys are together." Sam said, trying to hold back the giggles.

"Like…gay?"

"YES, like gay and homosexual and all that crap! Now can we please sleep before I have nightmares of this?"

Sam agreed, and an hour later, the brothers were asleep.

Unfortunately, Sam left his laptop on . And, Cas being Cas, the angel was curious.

"Destiel and Wincest." Castiel announced while the brothers ate breakfast that morning.

"What?" Dean asked, mouth full of bagel.

"That's what the slash couples are called. You and me, and you and Sam. Together."

Sam put his fingers in his ears. "No. Cas, shut up. Please."

Dean was tempted to cut his hand and shoo the angel away with a sigil. But instead he left the motel to get drunk and hit on girls, and Sam just followed to stay away from Castiel.

The angel read Supernatural slash for the morning. And afternoon.

So when the boys came with burgers and fries for dinner, Castiel decided to share what people really imagine about slash.

"Dean. This is Destiel. Personally, I don't think its that bad. And I do like the feeling of you touching my wings like this girl imaged." Before Dean could protest, or escape, Castiel began to read. Sam already was chuckling.

"The wings were beautiful, shades of silver-grey and white with a faint iridescence, more importantly they were a part of Castiel, a part that as far as he knew no-one out side of heaven had ever seen. He was so caught up in the effect this simple act of caring was having on him, it hadn't occurred to him how it felt to Castiel until he heard a soft sigh come from the angels throat and felt the tip of his other wing curve around to caress Deans side softly.

He smiled to himself 'You like that huh?'

Castiel groaned softly, 'Yes, you have no idea how good that feels to me Dean.'

'How about this?' Dean asked as he ran his hand with a gentle pressure all around the rim of a wing from shoulder blade to tip.

The angels' breath caught in his throat at the rush of pleasure that flowed through him. Deciding this was all far too one sided he trailed the feathers currently stroking Deans hip across the small of his back before stroking down to tease between the cheeks of his ass. Within moments Deans lips were pressed to his neck, his breath against his ear as he whispered 'turn around.'

'Why?' Castiel enquired breathlessly, he didn't want this to end yet.

He felt Dean grin against his neck as he answered. 'I wanna find out if you've got a halo.'" Castiel finished his story slip.

Dean's head was under his pillow, trembling. Sam was still laughing.

And Castiel was eager to show them more. "This my favorite part of wincest." he mused, still studying the screen.

Dean groaned in agony, and Sam abruptly stopped laughing. "CAS, NO!"

But unfortunately, nothing could stop Castiel. Some might say the angel was going dark side. With…slash. It only got worse.

"Dean was straddling Sam while kissing him feverously. Dean moved from Sam's mouth and led a trail of kisses along his jaw line, biting and nipping as he went. Sam moaned and Dean could feel his erection growing, the sound Sam made was music to his ears and he wanted to hear more of it. He nipped at Sam's ear then he slowly worked his way down to Sam's stomach."

Dean was now sitting on the bed, knees to chin, his body rocking back and forth. His face had a permanent shocked, very disgusted expression with wide eyes.

Sam would have laughed at the sight. If he wasn't staring at Dean like an idiot, his eyes wide and horrified. "I like Destiel better."

Castiel smiled happily and closed the laptop and sat down next to Dean, who was still in a trance. "I do too." he said, wrapping an arm around Dean.

Sam dropped to the floor.

He lay on his back, staring blankly at the ceiling.

When his phone rang, he really didn't want to answer. But he heard the voicemail.

"What the hell, guys? Seriously? Do you honestly expect me to write that down? I can't put that image to my head. THE IMAGES, OH GOD, THE HORROR." That was Chuck. Of course it was.

It was like that for a while.

Sam staring blankly at the ceiling, horrified. A satisfied Castiel playing with Dean's hair. And Dean's eyes still widened in disbelief.

You really don't want to know what happens later.
