     thing as mild necro?)

     [Title from something by Powerwolf]
Myrtle Beach, South Carolina.
Spring Break.
The college student’s grand adventure and the serial killer’s paradise.
And wasn’t that why they were there? Large crowds of nameless faces, some
traveling in packs and some traveling alone.
Sam was sitting on a beach that was milling with college students: young,
enthusiastic, beautiful. They were everywhere, and he was a combination of
unnerved and enraptured. He was sixteen so, while his attention was caught up
on the half-naked bodies all over the place, he felt a bit out of place.
Getting taller, still lanky, but he still didn’t feel that he fit in his own
skin yet.
Not like Dean.
Dean, whom was fit, built, tall, perfect, gorgeous, and a thousand other
synonyms that were flying through Sam’s head. And currently talking to a
handful of giggling college girls. His brother’s beautiful smile and gorgeous
eyes were magnetic, and he had been invited to join them not long after they
hit the beach.
Sam traced random symbols in the sand with a fingertip, eyes flicking to his
brother every minute or so. He knew why they were here – he had recognized that
look in Dean’s eyes before they had hit South Carolina. He hadn’t missed the
way Dean had been staring at random people for the past week, sizing them up
before mentally discarding them. He had been more aggressive, too; shoving Sam
up against walls at random moments, slipping hands down his jeans or biting at
his throat in public places. Not that Sam minded: he didn’t. At all.
He knew, yet that niggling doubt that was jealousy kept whispering in his head.
How could he compare to others like the girls his brother was conversing with
right now? He didn’t, not to them or the guys Dean’s age who were enjoying the
sun, some of them casting glances as his brother, also. Not even close.
Sam’s gaze lifted as a shadow fell over him, and he found Dean and two of the
girls standing in front of him. “We’re going to run up to the bar for some
beers,” the man told him, “I’ll be right back. You want anything?” Dean shot
him a grin and a wink, and Sam smiled and shook his head no.
He watched as they walked away, biting his lip. He had just turned his
attention back to his random symbols when he heard,
“He’s your big brother, huh?” One of the girls who had been standing with Dean
moments before had fallen back to speak to him, “You’re a cutie yourself. If
you were older, I would be all over you.” She shot him a saucy grin as he
flushed; his eyes met her brown gaze as she leaned close, giving him a close-up
of her cleavage in her tiny, red bikini. “I plan on taking big brother home
with me later,” she told him. Sam scowled a bit, and she grinned down at him.
She went down to her knees in front of him, putting herself at his eye level,
and leaned closer to press against him. Sam swallowed hard, eyes flicking from
her face to her cleavage, and she shot him another grin. “If you’re a good boy
and stay out of the way while he and I have a little fun,” she raised a finger
to trace it down his cheek, “I’ll come back and let you have a taste.”
She stood and blew him a kiss before turning to jog after Dean and the other
girl. Sam’s eyes followed her; he saw that Dean had stopped a short distance
away and was watching them. The girl reached him and linked an arm through his,
tugging him toward the boardwalk and the outdoor bar. Sam didn’t miss the look
Dean threw back at him, and he bit his lip again.
His brother was angry.
 
He had just exited the water and was talking to another boy his age about
surfing (neither of them knew how to do it, both wished they could), when a
hand on the back of his neck caused him to jump. Sam turned and found Dean
standing behind him.
He shot a glance at the teen he had been chatting with, who waved goodbye and
trotted up the beach, then raised his gaze to Dean’s. His brother stared at his
face for a moment before dropping his gaze to take in Sam’s wet body.
Sam could feel the flush touching his cheeks as his brother murmured, “Damn,
baby boy, you look good enough to eat.” He shot the other a shy smile, and Dean
leaned in closer, but not quite close enough to touch, “Might throw you down
and fuck you right here.”
Before he could respond, Dean’s features hardened suddenly.
“That girl was hitting on you?”
“What girl?” he asked blankly, staring up at the other. He was still caught up
in what Dean had said a moment before, “Oh, the one who was with you? ‘Course
not.”
“Really?”
Dean’s tone told him he knew otherwise, and Sam dropped his gaze for a moment.
He shrugged a lean shoulder and said, “She.. was kinda.. flirty. Mostly she was
telling me to stay out of the way so she could get to you.”
“Was she now?” his brother’s green gaze flicked to the left, to the two girls
he had been with earlier; they were sitting a short distance away, sunbathing.
That gaze locked on him again as Dean asked, “You want her?”
Sam shook his head no, “Only want you, Dean. Only ever want you. Do – do you
want her?”
His brother shot him a mischievous smile as he leaned in to whisper his answer,
“Yeah, but not like that. Go back to the room, Sammy. I’ll be there after I
take care of some -- business.”
 
Night had fallen several hours earlier, and Sam was sitting alone in their
hotel room, watching reruns of ‘Cops’. He raised his eyes as he heard the lock
turning: moments later, Dean entered the room.
He watched his brother cross the room, craned his neck back to look up at him
as Dean halted beside the bed. Before he could speak, the other’s fingers were
tangled in his hair and Dean caught his mouth in a possessive kiss. He
whimpered softly, and Dean growled in response and jerked him close.
“Get in the car, baby,” his brother instructed when they parted and Sam was
trying to catch his breath, “Got a surprise for you.” Sam watched him turn and
exit the room again; he grabbed his shoes to put on in the car and went after
him.
 
“Where are we going?” Sam glanced out the passenger window, into the darkness,
before turning his head to look at his brother. They had been on the road for
almost half an hour; they had stopped passing hotels and businesses a while
back, and were in a less populated area.
“It’s a surprise,” his brother told him, glancing over at him to shoot him a
smile.
Sam stared at him for a moment, memorized by the way the dashboard lights cast
their glow across Dean’s face. He blinked as Dean turned the car off the two-
lane highway suddenly, onto what appeared to be a small, one-lane dirt road.
Dean drove the car carefully through what appeared to be a field of some kind,
before stopping in front of an old barn. Sam watched as he climbed out of the
car and moved around in front of it: his form in front of the headlights threw
giant shadows on the barn wall. Dean pushed open the doors – Sam couldn’t see
much inside, only what the headlights cast their glow upon – before returning
to the car. He drove it into the barn and cut the engine, leaving the
headlights on. Sam watched him close the doors behind them, shutting them in
the somewhat spooky old structure. His brother motioned for him and he got out
of the car, shutting the door with a soft click.
Sam followed the man through the shadowed barn, eyes roaming the place. It
smelled of dust and old, mildewed hay, and was empty save for some rusted farm
equipment. It looked like the place hadn’t been used for anything other than
storage for a long time now.
“What are we doing here?” he asked, halting as Dean stopped in front of him.
His brother stepped aside, and Sam blinked in surprise.
The girl from the beach, the one who had told him she was coming back for him
after she had Dean, was lying on the dirt-and-hay covered floor. Her arms were
tied behind her back, legs secured as well, and she had some type of gag in her
mouth. Her face was streaked with dirt and tears and she was staring at them,
brown eyes wide and red-rimmed. She was clad in a short white top and a short
black skirt; her arms and legs were red where the ropes crossed her skin, so
they must have been tight.
Sam glanced over his shoulder as Dean pressed against his back and slipped
strong arms around him. His brother nipped his earlobe before whispering,
“Surprise, baby. Got her for you.”
Sam closed his eyes briefly in pleasure as Dean’s fingers slipped beneath his
t-shirt, nails scratching up his stomach. The other man pulled away and moved
to stand in front of the bound girl; she let out a muffled cry as Dean reached
down and jerked open her shirt, sending buttons flying and exposing a lacy bra.
“You want her, Sam?” the other man turned to look at him again – Sam saw the
anger lining Dean’s face – “She wanted you, didn’t she? You want her? Go ahead,
have her.”
Sam tilted his head a bit, eyes flicking to the girl for only a moment before
landing on his brother again. Dean was tense, fists clenched at his sides: Sam
saw them shaking, knew his brother was holding back whatever intense emotions
he was feeling. He crossed the dirt floor to press up against Dean, “Only want
you, Dean. I told you, I only ever want you. I don’t want anyone else, don’t
want you with anyone else. Just you and me.”
Dean swallowed hard, eyes searching his face, before speaking again, “Now’s
your only chance for this, Sam. I’ll never offer it again.”
He pressed a hand against Dean’s crotch, felt the shudder run through the older
man’s body. “Only want you.”
Dean jerked him close and claimed his mouth in a hard kiss, one hand tangling
in his hair and the other trailing down his back. Sam moaned and arched against
him, a soft gasp escaping him as Dean nipped hard at his bottom lip, drawing
blood.
The Brothers looked to the bound girl as she made a muffled sound; she was
fighting uselessly at her ropes, panicked gaze on them. “She’s pretty,” Sam
commented, eyeing her. His brother hummed against his ear, hand slipping down
to brush his crotch. “No, you’re pretty,” Dean murmured, undoing his jeans and
slipping a hand in, “You’re perfect.”
Dean pulled away when the girl let out another muffled cry. Sam watched as his
brother crossed to her and knelt beside her, pulling his knife from the sheath
at his boot as he did. The headlights glinted off the blade momentarily; Sam
tore his eyes from the weapon to look at Dean’s face. His brother was watching
him, knife to the now-sobbing girl’s throat, poised and waiting.
Waiting for him.
Sam swallowed, nodded yes: he watched as Dean trailed the tip of the blade
across her throat, drawing a thin line of blood and a muffled scream from the
girl. His brother smiled, pressed the blade against her skin, and drew it
across slowly, pressing down hard. The girl made a gurgling sound as the razor-
sharp blade sliced into her flesh, eyes wide in her pretty face.
Sam couldn’t breathe for a moment as he watched his brother wield the blade;
the pure pleasure on Dean’s face had him reaching down to grasp his dick hard
so he didn’t come on the spot. Dean’s green gaze shifted to him, roamed over
him, then the man growled softly, “Come here, Sammy.”
He obeyed and crossed to Dean, knelt in front of him, and the other grabbed his
shirt and jerked him forward. Their mouths crashed together in a bruising kiss,
fingers tangled in his hair, and he found himself on his back on the dirt
floor. His gaze shifted to the girl who was bleeding out inches from him, eyes
wide and sightless and staring in his direction.
Sam watched as his brother crawled up his body to straddle his stomach – the
man still held in his hand the blood-wet knife. He nodded yes, almost
frantically, as his brother growled, “Mine.”
“Yours, Dean. Only yours, promise, just yours.”
Sam arched his hips hard against his brother and Dean groaned, rocking against
him. “Want to fuck you, baby boy,” the older man leaned down to bite at his
throat, bruising the skin, and Sam’s hips stuttered against him again.
“Fuck me, Dean. Please. Right here.” He grabbed at the other’s shirt, trying to
pull him closer, and Dean shot him a predatory smile that sent a shiver of lust
through him.
“You want fucked on top of this bitch’s body, Sammy?” his brother purred in his
ear, slipping a hand into his unbuttoned jeans to run fingers along his shaft,
“I killed her for you, baby. She wanted what belongs to me.”
“Yes, Dean, please,” Sam’s voice was breathless – Dean’s hands were stealing
his breath, setting him on fire – “Anything, please. Fuck me.” His brother was
tugging at his clothes then, jerking off first Sam’s shirt and then his jeans
and boxers, and tossing them aside.
His head fell back, exposing more of his throat, as the other’s knife was
suddenly pressed against it. A full-body shudder ran through him as Dean traced
the sharp blade along his skin gently, carefully, leaving a thin trail of the
girl’s blood but not drawing any of Sam’s.
“Trust me, Sammy?”
“Always,” he whispered, reaching out to grasp his brother’s free hand. He
pulled it to his mouth, brushed his lips against Dean’s wrist, “Always trust
you, Dean. Only trust you.”
“You’re perfect, Sammy,” Dean’s soft smile, the love in his eyes, sent Sam’s
heart stuttering against his ribs. He sighed in pleasure as the tip of the
knife brushed over his collar bone before slipping down his chest to trace
around a nipple. Sam shuddered again as Dean leaned in to catch his nipple in
his mouth, sucking lightly. Strong fingers wrapped in his hair, pulling his
head back, and Sam whined in need.
His entire body jerked in pleasure as he felt the knife press into the flesh
just above his right nipple. There was a sharp sting as the knife separated the
skin; Dean’s mouth was covering the small bleeding cut seconds later, sucking
hard at it.
The sensation went straight to Sam’s cock and he began to come with a sharp
cry, sudden and unexpected. “Yeah, good boy,” Dean murmured against his skin,
hand cupping over Sam’s cock to catch the hot fluid. Sam watched, breathless
and shaking, as his brother sat up and raised his hand to his mouth, licking
and sucking Sam’s cum from it.
Dean smirked down at him when he had finished licking his hand clean, leaned in
to nip the skin just below Sam’s ear.
“Wanna play dirty, Sammy?”
Sam moaned as his head was pulled back; his eyes met the dead girl’s next to
him as fingers forced his face to turn to the side. He was pulled up from the
floor suddenly, shoved toward her on his hands and knees, as his brother
ordered, voice little more than a growl,
“Suck her tits, baby.”
He obeyed as his face was shoved down against the dead girl’s cleavage, which
was streaked with her blood. His face was pressed into her breasts and he took
a nipple in his mouth, sucking on it. Fingers dug into the back of his neck as
his brother groaned,
“Yeah, baby, that’s it. Suck it.”
Sam saw his brother’s free hand move to the girl’s other breast, squeeze it
tightly and run a thumb over her nipple. Dean trailed his fingers through the
blood that was running down her chest, squeezed her again with another growl:
he moaned against the nipple he was sucking as, moments later, those blood-wet
fingers wrapped around his cock, which was half-hard again already. Dean
stroked him several times before running his hand through the blood trickling
from the girl’s neck. His hand disappeared from sight after a moment; Sam
moaned again as he felt wet fingers slipping down his crack to press between
his ass cheeks.
“Only way I’ll ever let you touch anyone else like this, Sammy, is if they’re
dead. If they’re not then they will be when I’m through. You get me?”
He nodded yes, rocked back against his brother’s teasing fingers.
The fingers in his hair pulled his head over, forced his face down against the
girl’s other breast, and Sam took the girl’s nipple between his teeth. He bit
down on it – Dean groaned behind him, slipped a finger into him – then began to
suck it.
A second finger slipped into him and Sam arched back hard against Dean’s hand,
trying to take more. He whimpered, a mixture of pain, pleasure and need, as his
brother began to scissor his fingers into him, opening him up.
Sam whined in protest as Dean removed his fingers: the older man trailed them
through the dead girl’s blood again, before slipping them back into him. His
brother added a third finger, pressed deep to brush against his prostrate, and
Sam cried out in pleasure,
“Dean, please, more!”
“My good little whore,” Dean’s voice was wrecked as he pulled his fingers free,
pressed his cock against Sam’s opening. He jerked Sam away from the girl
beneath him, growling, “Get off that bitch. You’re mine.”
“Yes,” Sam nodded, shuddering as Dean pulled his hair hard, “Yours.” He rocked
back against his brother, begging with his body. Dean pressed his cock into
him, pushing past the tight ring of muscle, pressing deeper. It burned as the
man entered him, pushed deeper; for a moment it felt like it was too much, but
Sam wanted more. When his brother was finally buried to the hilt inside him he
whispered, voice breathless,
“Fuck me hard, Dean.”
His brother complied, pulled his dick out to ram it back in. Dean’s hand
gripped his hip, marking it with bruises, as he began to pound into him. His
brother made certain to hit his prostrate with every thrust inside him,
stealing his breath and shooting pleasure through his entire body.
“Feel so fuckin good, baby boy,” the older man leaned over his back to growl in
his ear, “My little whore.” The man’s teeth sank into his shoulder – Sam cried
out in pain-pleasure. Fingers tangled in his hair and Dean jerked his head back
and commanded,
“Look at her, baby.”
He obeyed, opened his eyes to look at the girl lying next to him. Correction,
he was nearly lying on top of her now; Dean’s thrusts into him, driving him
forward, caused her lifeless body to shake.
“That is what I do to anyone who touches you,” Dean caught his earlobe with his
teeth, sucked it for a moment, “I told you I would fucking rip open anyone who
fucks with you, baby boy. You belong to me, and I will end anyone who tries to
change that.”
“Dean,” Sam gasped out his brother’s name as the other man’s fingers slipped
out of his hair to wrap around his throat. The man pressed hard, restricting
his intake of air, and Sam moaned and rocked back against him.
“Like that, don’t you baby? Like it when big brother fucks you like this.”
He nodded yes, whispered, “Yours, Dean.”
When his brother whispered breathlessly in his ear, “I’m yours, too, Sammy,
only yours,” Sam began to cum hard. His brother’s fingers were on his cock
then, stroking him through it, and the pleasure overwhelmed him. His vision
went black momentarily as he shot, white streaks of cum shooting up over his
stomach and over the dead girl beneath him. He gasped out “Love you Dean,” and
the other man groaned and slammed hard into him, cock pulsing and hot come
filling him.
When his vision cleared a bit and he could catch a breath, Sam realized he was
lying on the girl’s body, and Dean was lying on top of him. He shifted, tried
to push himself up, but Dean’s weight held him in place. He felt the other
man’s lips press against the side of his neck, planting light kisses, and
shivered.
“Let me up, Dean,” he tried again to raise up, and Dean chuckled against his
skin.
“Like you right here, baby boy.” The man’s voice was a husky growl – Sam
shivered again at the sound of it. Dean always did have a way of undoing him
with that voice.
A smirk touched his mouth as he said, “Okay, I’ll just lay here on top of her
then.” A growl escaped the other’s throat and Dean relented, slipping out of
him and rolling off of him. Hands pulled him up, away from the girl on the
floor; he found himself in Dean’s lap a moment later.
He leaned in, caught his brother’s mouth. The kiss was surprisingly sweet,
Dean’s fingers stroking gently down his face and neck and sides. And wasn’t
that an odd thought, Sam noted mentally, considering they had just fucked on
top of the body of someone his brother had killed and were covered in their
fluids and her blood.
Sam stood and stretched his aching body before glancing down to find Dean’s
eyes on him. His brother shifted to his knees, leaned forward to trail his
fingers up Sam’s ribs. The man pressed lips against his chest, over his heart,
fingers trailing over his sternum; Sam’s breath caught in his throat as Dean
raised his eyes to him and told him,
“One day I’m going to carve my name into you, Sammy.”
“Dean – “ his own voice was a wrecked whisper, fingers clutching Dean’s hair.
He swallowed hard and nodded, “Want that.”
The other man shot him a smile that was nothing short of beautiful before
pushing himself to his feet. He watched as Dean did up his jeans before
retrieving his own discarded clothing. He tugged on his jeans and t-shirt,
grimacing as the fluids covering him caused them to stick to his skin.
Good thing their motel room was the end room. They were both a mess. He hadn’t
realized he spoke the words aloud until Dean began to laugh. He shot the man a
sheepish grin, went willingly as his brother pulled him close for another kiss.
Fifteen minutes later, they were driving down the dirt road toward the highway,
and the barn - and the body in it - was burning behind them.
