Things We Do for Cas

Rated M

Eventual Wincestiel.

Response to a Stories4Charity prompt from Ethnedragon. Who simply stated, "Anyone brave enough for some Wincestiel?" Well...yes I am, actually. I just haven't stuck my toe in those waters yet, as far as writing it.

Summary: Castiel has a problem. There are only two people he knows he can trust; two people he loves more than anything else in God's entire creation. This is in the "Things" verse, but stands alone. Aka you don't need to read the others to read this one. Likely, this will be in three parts.

He came to them during lunch. Sam and Dean were sitting down to Dean's extraordinarily delicious burgers, and a couple of beers as Sam thumbed through a file. Dean was mid-chew when the angel zapped into the bunker unexpectedly, his body doubling over a bit.

"Cas?" Dean's worry was evident in his voice as he threw his burger to its plate and pushed up from the table. He approached the angel who looked to be in some sort of pain, and began searching for an injury as he led him to sit down at the table. Sam was beside him in an instant.

"Cas, what happened?" Sam asked. "What's wrong?"

"Please," Cas said, shaking his head. "It's...I am not injured."

Dean pulled back a bit and turned another chair so that he could sit down in front of him. "Then why do you look like someone just messed with your insides?"

The angel's eyes were darting around in the air between them. He was very much aware of Sam crouching down near his legs, and the hand on his knee felt like fire burning through the fabric of his pants. He fought not to shove it away. "It's...complicated," he replied.

"Well you know you can tell us anything, Cas. Right?" Sam offered.

"Of course," Castiel replied. "That's...that's why I'm here. I don't know what to do..."

"You've gotta tell us what's going on, first," Dean told him. "Or we won't know what to help you with."

"I... I am uncertain of the cause," he began. "My vessel...it's empty aside from me. Yet I seem to be suffering from...urges that I am unable to fulfill."

"Urges?" Sam raised a brow.

"Sexual urges," Castiel elaborated, finally meeting their eyes. "All of my past sexual encounters with females have ended in disaster or betrayal. I've found myself unable to desire them any longer, let alone trust them."

"Are you telling us you're suddenly gay now?" Dean asked with raised brows.

"Angels do not have a gender," Castiel replied. "We don't have a need to reproduce. We're not supposed to have...these feelings."

"But you're having them," Sam replied. "Did you come across something lately? Maybe a cursed object? A witch?"

"Those things wouldn't affect me," Castiel replied.

"Maybe they would, though," Dean supplied. "That grace you've got is running low."

"And you were human not that long ago, Cas," Sam reminded him. "Who knows what's going on with your body."

"What, you think he's going through some kinda puberty?" Dean looked at Sam with a raised brow.

"No... I dunno," Sam shrugged. "It's gotta be different than that. This is kind of a new phenomena."

"Or Metatron messing with things," Dean suggested.

"Maybe. But this... the fact that he looks like he's in pain... It's almost like he's...in heat," and the moment the words were out of his mouth, the brothers both realized the wave of warmth radiating from the angel. Sam pulled his hand away from the angel's knee, and Castiel seemed to curl in on himself.

"Holy shit," Dean said in almost a whisper.

"Cas, do you want us to help you find someone?" Sam asked. "You know...to help you out?"

"I don't trust anyone in that way," Castiel told him. "I don't much trust anyone for anything. Except for the two of you." He didn't meet their eyes when he said it, but Sam and Dean glanced to each other.

"Are you..." Sam started as he turned back to the angel. "Cas, are you asking...for me and Dean to..."

"I'm sorry," Cas cut him off and pushed up out of his chair, grimacing as he did. "I shouldn't have asked such a thing from you. I should go... I should... Is there an establishment like the one you took me to before, except with male prostitutes?" he asked Dean.

"Cas, listen-"

"I would rather not do this with strangers, but-"

"Cas, just hold on a minute, okay?" Dean said more firmly. "Just... Look, gimme a minute to talk to Sam, okay? Don't go anywhere."

"Dean," Sam said before Dean grabbed his hand and pulled him toward the kitchen. "Dean, if you need to do this..."

"Shut up, man," Dean said once they were out of the room. He turned to face his brother. "I'm not doing anything without you."

"I just feel like... Well, you and Cas have this connection. You always have. And if he needs someone right now like this, I think it'd be better if it was you rather than some stranger."

"You think he doesn't care about you as much as he does me?" Dean asked with a raised brow.

"I..." Sam was thrown by the comment for a moment. "I think it's different. I think he cares about me because you care about me."

"That's not true, Sam," Cas called out.

"Crap," Sam looked to Dean with widened eyes for a moment. "I forgot he could still hear us..."

"Cas, could you please turn off the sonic hearing for a second?" Dean yelled out. Then he turned back to Sam. "When I said I wasn't doing anything without you, I meant that we should both help him. Together."

"Both... You mean, you, me, and Cas? Like...like a threesome?"

"Yeah, like... Yeah, a threesome. I mean, if you want. Because I could probably help him track down a gay club somewhere. It's not like we've gotta worry about Cas. He's an angel. He can take care of himself."

"No. No I know he could, but I don't think it should... No we can do this," Sam nodded nervously. "You think...Cas would want me in this?"

"His choice is both of us or somebody else," Dean stated. "I just wanted to make sure you were game before making the offer." It's then that he noticed Sam's eyes. They were dilated, and he was breathing just a bit quicker than normal. Dean couldn't keep a sly grin from forming. He took the few steps forward so that he was a breath away from his brother. "You're more than game, aren't you?" he said, not really meaning it as a question. "Just the idea of this is turning you on. You're even kinkier than I gave you credit for, Sammy."

Dean pulled him into a heated kiss, hands snaking up into Sam's hair as his leg pressed between both of Sam's. The younger brother whimpered into Dean's mouth, his own hands grasping at the sleeves of Dean's over-shirt as he pressed his hardening cock against Dean's thigh.

Dean pulled out of the kiss. "Yeah, I think this'll work out just fine," he told him. "Hey, Cas!" he yelled.

"Yes, Dean?" the angel replied, sounding a bit pathetic.

"Go to my room. Take off your clothes. We'll be up in a minute.."

Tbc...
