Title: Shifted
Pairings: Dean/OMC, Wincest (Sam/Dean)
Warnings: dub-con
Summary: fic prompt - A shapeshifter taking Sam's form tells Dean all the fantasies Sam's had about him.
The 'shifter's got Dean pinned against the wall, one hand at his throat and his eyes flashing silver against the painfully familiar hazel.
"Where is he?" Dean rasps, struggling against his hold, but this shifter either knows how to work Sam's bigger body or he's just naturally stronger. Probably both.
The shapeshifter grins at him, cheeks dimpling and it just looks wrong, this monster using Sam's features to form his smile. Dean struggles more.
"Ah, ah, ah," he tsks, pressing into him harder, hips pinning Dean against the wall and his free hand gripping his wrists. "I think I'll just stay here for a little while, enjoy doing what Sam has never had the courage to."
Dean stills at that, eyes going wide. The thing wearing Sam's body smirks.
"Oh, you didn't know that, did you?" he breathes, hot into Dean's ear. "The things Sam thinks about you..." He chuckles, dirty and low. "They're enough to make even me blush."
Dean tips his head away when the shapeshifter trails a finger along Dean's jaw, stopping on his lips. "See, like most people," the thing leers. "He loves these. Wants to see them stretched and split around his cock." Dean makes a strangled sound, eyes huge.
"You're lying, you filthy sonuva-"
"Now, now, Dean," the monster croons, squeezing Dean's neck. "Is that anyway to talk to the one who's letting you live?" Dean nearly spits at him, teeth bared, and the shifter just laughs.
"You know what else he wanted to do?" he continues, almost as if Dean had never interrupted him. "He wanted to take this tight ass," he gropes him blatantly, eyes lidded and lascivious. "And pound into it. Hard," he grins, right in Dean's space. "Especially when you were mouthy. Apparently, he's thought a lotabout it when you're a dick. Wants to fuck that attitude right out of you."
Dean can't even breathe at this point, unable to stop the strangled whimper from falling from his lips, picturing everything the monster is saying from those familiar lips in vivid detail. He can almost taste their sweat, the way he'd be panting like he'd run a fucking marathon, and how Sam's low, sweet drawl would crawl up his spine and turn him into a puddle of useless nerves.
Fuck, now he's got a fucking hard-on, and that's just great, seeing that sickly, simpering smile on Sam's lips and knowing it isn't actually his pain-in-the-ass little brother.
Hopefully to be a literal pain-in-the-ass soon.
"Gettin' a little excited there, Winchester?"
Dean growls, shoving at him. "Get off."
"I don't think so," the shifter coos, trailing his fingers along Dean's happy trail. "I think I'm gonna take what your little brother clearly is too chickenshit too."
Dean's eyes widen and he struggles harder against him, hips bucking to try and dislodge the hard, lean body that isn't Sam, if only his fucking cock would remember that!
The shifter's hand is down his pants and he's biting back shaky moans and pushing him-he doesn't want this, stop, stop-when suddenly there's a spray of blood and a gurgling sound from the shapeshifter until he's forcibly shoved away. Dean falls to his knees and looks up to see Sam, real, actual,beautiful Sam, and he reaches out to fist his hands into his jeans, pressing his nose to his hip and inhaling shakily.
"Oh, thank fuck," he breathes, closing his eyes when he feels Sam's hand in his hair.
For now, he just needs this.
Later, he can use what the shapeshifter told him and put it to good use.
A/N: I don't post much Wincest but I actually do ship it...so here, have some.
Please review! I'd love feedback!
