The Naiad spirit lives in the rain, the nymph especially comfortable in the swamp, singing in the trees and bedeviling passers-by on the adjacent highway. A playful and annoying sprite, it likes to cause people's cars to stall, always when it's pouring outside, to make sure the drivers get nice and wet when they're trying to figure out what's wrong with their engines. They always, unless they call for a tow truck, end up in the swamp and the Naiad takes great pleasure in kicking them face first into the mud, giggling into its ethereal hands, watching as the drivers struggle their way out of the mire.

It's all pretty harmless fun, at least on the spirit's part but this particular one has turned nasty, not content on mere mischief-making anymore, it's actually hurting people, holding them down in the mud until they suffocate.

Sam found out that an incantation, held over a special bowl that was forged in the fires of some Greek blacksmith, combined with the right herbs and oils, could imprison the Naiad and then banish it to a celestial plane. So here they are, armed with all the ingredients, bowl in hand (thanks to Bobby) and now Sam just has to talk Dean into using the Impala as bait, no easy task but Sam is back in full form, hasn't had a drink in days, and is not about to take no for an answer.

The rain is pouring down now. Sam carefully puts the bowl in the road, lining it up with the tire of the Impala.

"Think you can hit that?" He challenges Dean.

Dean turns the key and his shoulders relax as the engine catches easily. Thank Christ that stupid sprite hadn't done permanent damage to his baby. Otherwise, he'd be tempted to just leave it in the bowl forever. He actually still doesn't know why they have to send it back to its home but Sam says they should so-

He rolls down the window and leans out, getting drenched in a second from the rain, maneuvering the front wheel over in front of the bowl, gunning the engine and rolling over it, flattening it down onto the road. With a loud pop and a hiss of steam, the Naiad is sent back to its realm and the drivers on the highway are safe now from its vengeful sense of humor. Dean rolls over it with the back wheel just to be on the safe side.

Dean sees Sam in the rear view mirror pick the flattened bowl up and wave it at him, giving him a thumbs up. Dean pops the trunk and Sam tosses it in, then gets in the car, sitting on the seat with a wet squish, clothes sopping wet just like Dean's.

Dean hits the gas and they speed away into the night.

The car windows are misted up, rain pouring down outside, droplets trickling down the inside, the hot, wet bodies of the brothers making the air heavy and damp, Two mouths exhaling into the muggy, stale air cause the inside of the car to be soggy and close. To Dean, it's like breathing through a wet washcloth, slapping against his nose and causing him to hitch his breath in with shallow pants that don't reach his lungs and make him feel dizzy and unfocused.

Sam's looking out the window at the rain, hair dripping down his neck, clothes thick and heavy with water, squishing around on the seat, reaching out to aimlessly draw circles in the steamy window. The smell of him, musky, sweat and adrenaline mix together with the rain, fill Dean's head with erotic possibilities. God, he smells so damn good and Dean can't breathe in here 'cause the air's so thick with the smell of Sam.

"Jesus, Sammy," he grates out, "You wearing fucking aftershave or something? You stink, man!"

Sam's panting slightly, too "I'm not wearing anything, Dean and you don't smell too good yourself."

"Lot better than you, that's for sure."

"Says you. From over here, you smell like shit."

"Christ." Dean mutters and rolls down the window, the rain pelting him as the fresh air rolls in and he takes big gulps of it to get Sam's smell out of his nose and thoughts, pushing away the image of his brother that's been with him for the past three days.

Sam, beautiful and broken, splayed over that damn chair in front of him, ass all red and welted, dick thick and heavy between his legs and after he'd finished whipping Sam with his own belt, Sam had struggled to his feet and gone in the bathroom to take care of that gigantic hard-on. Dean had gone out to the car to jerk his off, 'cause his excitement was just as large as Sam's and they had gone their separate ways to do their business when they should have been together, taking care of each other and this whole thing just sucks.

Now, Dean drives faster, needing to get them back to the motel, needing to get out of these wet clothes and this steamy car as fast as he can before he pulls over and jumps on Sam right here in the car because that's how close he feels to just losing what little control he has left.

He's had about enough of his stupid brother, is just sick of him, sick of constantly resisting him, sick of not letting himself have Sam–

And Dean's just reached it, that final straw, right here, right now and he drums his fingers on the steering wheel, whistling mindlessly through his teeth, his eyes glittering hard, staring beyond the road, beyond the windshield wipers flicking and flowing, staring to just ahead, hot shower, dry clothes and getting away from this goddamn fucking smell that's just driving him crazy and making his jeans pull tight over his growing erection.

He squirms in his seat, trying to give himself more room but he's so hard, it's starting to hurt and he's gotta hurry cause shit, when he finally gets there he's so gonna jerk off and he doesn't care if Sam's watching or sells fucking tickets 'cause he's just gotta-

Sam gives a quiet sigh, jeans rustling wetly, the sounds of Sam's breathing so loud in his ears that he can't stand it and when Sam licks his lips, pink tongue sliding out in the dark, Dean's breath stops, just stops in his lungs, chest so tight he can't get it to work-

Can't wait, can't wait, shit, he just can't wait any longer and that's it-

He yanks the steering wheel, pulling off the road and slamming it into park.

"Dean?" Sam looks over at him, surprise on his face.

He doesn't answer, just rolls up the car window and gets out, slamming the door shut behind him, striding away in the rain. They're in the woods somewhere and Dean's boots crackle on the wet moss and leaves, snapping twigs as he moves quickly in deeper, into the trees, away from Sam.

"Dean?" Sam's right behind him, "What's up?"

"Sam, go back to the car. I need a few minutes."

"For what? You ok?"

"Fine. Just go back to the car."

"No, Dean, not 'till you tell me what's going on."

"Damn it, Sam! Can't you for once do the fuck as I say without arguing with me?"

Sam flinches in the face of Dean's sudden anger, confusion ripping across his face and he shrugs, palms up, "What the hell, man?"

"Go. Back. To. The. Car." Dean's voice is clipped with rage.

"No."

With a muffled curse, Dean snaps, stalking up to Sam, body bunched and angry. Sam tenses, looking like Dean's gonna slug him and when Dean grabs him behind the neck with both hands to yank him forward, Sam catches hold of Dean's wrists to hold on, tries to keep his balance but falls forward into Dean's mouth, hitting hard, teeth crashing and Dean's sucking out his breath, roughly shoving his lips apart, kissing him angrily, punishing him.

Sam struggles against him for a second and then softens, a moan working up from his throat and he opens up for Dean, bringing his hands behind Dean's head, holding him gently, letting Dean be rough, letting Dean hurt him, without fighting, without pulling away, just standing there taking Dean's punishment.

Before long, Dean's anger is gone and the stinging kiss quickly turns passionate as they rock together, hips rubbing and bucking, teeth biting and sucking, hands clawing, gripping, fast and hot against each other.

They pull apart, panting hard, the air heavy and shimmering between them, the rain falling down, and they stare at each other, eyes locked in anger, in heat and then they crash into each other again, sinking down onto the wet moss and sticks, tearing off shirts, wanting to touch skin to skin, shoving against each other, no more waiting, no more excuses and hands are everywhere, stroking, pinching, twisting, squeezing, causing pain and pleasure at the same time.

"Son of a bitch!" Dean grunts out harshly, "Stinking bastard! You shoulda just stayed in the car!"

"Nobody said you had to kiss me, jerk! What the fuck, huh? What happened to 'we can't do this'?"

"We can't…we can't…" Dean grits out, capturing Sam's mouth again and sinking down into heaven, letting himself have it, "Damn you!"

Sam sinks his teeth into Dean's bottom lip, pulling sharply, causing Dean to cry out in pain and he grabs Sam's hair, yanking his head back, holding Sam in place, panting, "Let go or I'll rip it out, Sam!"

Sam releases his mouth and Dean bites at his neck, sucking wildly, marking him with purple bruises, making Sam gasp and writhe underneath him-

And Sam's fingernails, bitten and chewed to sharp edges, scrap down Dean's back and reach between them, unbuckling Dean's pants and pushing down, running his hands over Dean's tight ass, squeezing roughly and pulling him forward, tight against his own hips, bucking up against Dean's, rubbing and pushing and he pulls Dean's head down to his, mouths crushing into each other, lips smashed flat against teeth, sucking, all tongues and lips and-

Dean's ass works and Sam's hands yank him forward, squeezing and pulling Dean's ass wide open and Sam's damn fingers are inside him, making Dean groan out his pleasure, making him grind down harder, muscles tightening as he rocks against Sam's dick with his own. The stiff denim between them is rough and wet, the insane friction driving them both higher and the fire in Dean's belly spreads out, warmth flowing sweetly through his balls and legs, up his spine and down to his toes.

Dean stiffens over Sam, raising himself up on his arms as he reaches the edge of orgasm, suspended for a second before he rocks his hips into Sam's one more time and tumbles over the side, breath comes out in a shuddering gasp, body jerking as he explodes, exhaling almost a sob, "Holy Fuck, Sam!"

He collapses onto Sam who's still bucking and shoving, chest gasping for breath under Dean's weight, hips slamming up into his brother's, whimpering, straining until finally, he groans, low and deep, "Here-ahh, here it is…"

He gasps with each thrust, pulling on Dean's shoulders and then burying his face into his brother's neck, trembling with spasms as he shoots off in his jeans, huffing into Dean's warmth, sweat mingling with tears and he hugs Dean tight to him.

They rest together, anger gone now, violence lulled into a calm peace and they bump quietly against each other in the dark, their faces pressed into the moss, the rain, forgotten in the throes of passion, falling gently on them.

Dean touches Sam's face with a finger, running it along the side of his cheek and down to his chin, watching the rain fall onto his brother's nose and eyelashes.

Sam smiles at him, a shit-eating grin if Dean ever saw one, "Still mad at me?"

"Hell, yeah! All I was gonna do was jerk off. You shoulda stayed in the car!"

"No, Dean, I shouldn't have. I'm supposed to be right here and the sooner you admit that to yourself, the happier we'll both be."

"This is a one time thing, Sam. Tomorrow, we're back to not doing this anymore."

Sam chuckles, "No way, Dean. I'm not going back."

"You don't have a choice."

"Yeah, I do. I'm not going to let you do this again. So you better just deal with it."

"We'll see, Sam."

Sam continues to grin at him, unnerving Dean a little, "What?"

"It's just gonna be fun wearing you down, that's all. I can think of worse things to do with my time than drive you crazy with wanting me."

Dean smiles back at him, a real smile, his first in weeks, and gives a big sigh, "Sure did miss you, jerk."

"Missed you, too, Dean."
