Dean rose to the surface of consciousness quickly. The last thing he remembered was laughing with Sammy and taking a gulp of his beer.

Now, he was blindfolded, arms shackled above his head. His feet were just above the ground - if he pointed his toes, he could almost touch the floor. And he was naked. What the hell?

Okay. So he was maybe panicking a bit. He was a hunter, he wasn't used to having his senses impaired. Sure, he'd been tied up before, blindfolded, slammed against walls, beaten up by women (in his defence they were possessed or not human.) But he never got used to this. He would just have to rely on Sam or Bobby to help him. Maybe he'd find out who his kidnapper was if he just waited long enough and used his ears.

He heard a shuffling from somewhere to his left. Raising his head, (it wouldn't help, he was blindfolded) he turned in the direction of the sound.

"Hello?" he rasped. "Look man, you should just let me go. Cause my brother's gonna find you and he'll KICK YOUR FUCKING HEAD IN."

A chuckle. "Don't think I can physically kick my own head Dean."

"Sam? What's going on? Untie me dude!" Another chuckle - it sounded vaguely sinister if he was completely honest - something he thought he'd never say about his baby brother.

"Don't worry Dean. I'll let you go. Eventually." Sam's voice was like dark chocolate, seductive. Yet again something he never thought he'd associate with his brother.

He didn't want to think of Sam like that, there were some things brothers didn't talk about. Well. Sam didn't talk about. When Dean got drunk he was known to start talking about conquests. Maybe act some stuff out. Sometimes using Sam as willing participant. But they didn't talk about that.

"Sam? What the hell? Tell me what's going on?"

"I waited Dean." What was he talking about?

"Waited for what?"

"For you to realise. I got you drunk, we kissed. I thought that was it, that we'd finally be together! But then, the next morning, you just pretended you couldn't remember anything. I waited Dean! I've wanted you since I was a teenager!"

"Sammy, what are you talking about? Kissing? We're brothers!"

"Don't pretend you don't remember Dean. I can tell when you're lying."

Sam's voice had travelled now - it was coming from behind where Dean was suspended. He could practically feel the heat radiating off his brother.

Okay, so he did remember. That kiss with Sam had been incredible. But it was also incest. It was wrong. It didn't mean anything, they'd been drunk, needing comfort. They'd turned to the closest warm body available.

But… The memory of Sam's warm lips, the needy sounds that came from him when Dean had traced his tongue along the seam of Sam's lips…

And yes, there'd been a mark on Sam's neck, a dark purple bruise that Dean had worked on whilst Sam had gripped his shoulders and moaned, but that meant NOTHING.

God, if his father had still been alive, Dean most definitely would not have been.

Sam had wrapped his arms around Dean, his moist breath puffing against his neck. Dean restrained himself from leaning back into the touch.

"Sam. What are you doing? Just let me go, we can pretend nothing happened." Sam's arms tightened around him before stepping back.

"That's just it Dean" he snapped in a clipped voice. "I don't want to forget. I know you haven't forgotten that kiss." His voice turned low and husky. "How hard you got just from kissing me. How every time you saw that mark on my neck you'd get turned on.

Dean bit back a groan. "Sam…"

"Ssh Dean, just relax, let me do all the work." Dean felt Sam wrapping his massive hand around his - Oh God, already half hard - cock.

His head fell back, supported by Sam's shoulder. Sam was muttering nonsense words into Dean's neck as he worked his hand along Dean's length, twisting his hand just under the head. How the hell did Sam know how to get Dean so close to the edge so quickly?

Actually, that was a line of thought Dean didn't need right now. Sam's obsessiveness was freaking him out a little, he needed to get back in the moment, where he was currently getting a fairly awesome hand job.

Sam licked Dean's sweat sheened neck, groaning low in the back of his throat.

"Want you Dean. Want you to fuck me."

Dean jerked in Sam's grip.

"Jesus, Sammy! What's the matter with you? Why are you doing this? Let me go!"

"Can't, Dean." Sam was panting in his ear, voice shaky as he spoke. "Can't let you go until you accept this, what we're doing. Till you're ready to love me."

"I do love you Sam! But this, it's wrong! We can't do it!"

"Your dick seems to like it just fine." Sam gave an especially brutal tug to emphasise. And he was right. Dean was hard, harder than he'd been in a long time.

"Besides Dean, we've always been on the outskirts. No one has to know if we don't want them to."

"God Sam. How long have you been thinking about this?"

Sam huffed a laugh against Dean's ear. "A while. Since I was a teenager. First time I jerked off, it was hearing you and some slut having sex." Sam's tongue traced the shell of his ear, following it down to his neck.

"First time I fingered myself, I came without touching my cock, just because I could hear your voice in the next room." He bit down hard on Dean's neck.

And that was it. Powerless to resist, Dean came.

He could feel Sam stroking him through the aftershocks, murmuring words against his neck.

"Sammy" he groaned.

"Yeah Dean?" Sam asked lifting his head to brush against Dean's lips.

"We are so fucked up." Dean muttered, before opening his mouth and accepting Sam's kiss.

So... What did you think? First time ever writing something remotely like sex :P I don't think I did too bad...

Should I keep this as a one shot? Cos I feel like it could be more. Opinions?
