Never in his life had Sam been this intimidated by the sight of a jacket.
The bunker was still and quiet as Sam stood in the library, trying not to breathe, his gun wobbling as he pointed it towards the red jacket that lay on a book-covered table. It was the same jacket that Sam’s demon brother had been wearing. The same demon brother who was currently stalking through the bunker, searching for Sam to kill him or torture him or Sam didn’t know what.
...And now Dean was stalking around without his jacket. That meant he was left wearing a too-tight black t-shirt that left his arms bare, hugged his pectoral muscles and came a little shy of his jeans so that his toned belly and treasure trail would sometimes peek out—
Sam tore his eyes away from the jacket, still holding his breath. He didn’t dare inhale. He could already feel the smell tickling at his nostrils.
That jacket was covered in the pheromones of an eager, ready, horny alpha. And Sam was in heat right now. His heat didn’t care that the smell came from his brother, all it cared about was being bent over the nearest piece of furniture and fucked senseless.
Sam bit his lip hard and stalked away from the jacket, leaving the smell behind. He had to find Dean fast, before his own biology got the better of him. As he passed into a new room, Sam sucked in desperate gulps of clean, unscented air.
Sam’s whole body jolted when his phone buzzed in his pocket. He huffed out a shaky breath and pulled it out.
Dean Calling
Sam clenched his jaw. With a scowl, he picked up and pressed the phone to his ear. “The fuck are you playing at, Dean?” he whispered, keeping his voice hushed.
“You find my present yet, Sammy?”
Sam swallowed. The thick, heady scent of an aroused alpha still clung to his skin, following him like a ghost. “...It wasn’t my size,” Sam grunted. He peered around the corner, holding his gun ready.
“Heh, I know something else that isn’t your size.” Dean’s low voice made Sam shiver. “Still gonna make it fit.”
Sam nearly dropped the phone. He struggled to keep his breathing steady. “...Speak up a bit, Dean,” he murmured, creeping through the next room with his gun up. “I can’t hear you.”
“Don’t like my bedroom voice, baby?”
“Sorry, didn’t catch that.”
“You’re a real riot, but I don’t plan on giving away my position just yet.”
Sam rounded another corner. Nothing but furniture and dim lamplight. He paced slowly through the room, not saying a word, listening as hard as he could.
“...Not gonna play? You’re no fun.” Dean snickered. “Or maybe you’d rather stay quiet and hear what I’m gonna do to you. A little foreplay to get you all hot for me, huh?”
Sam’s heart pounded. He couldn’t tell if Dean was joking or not.
“You know, before you ruined my evening plans, I was about to find myself a nice slice of ass to destroy.” Dean let out a low noise into the phone, an eager growl that made Sam shiver. “But then you locked yourself in here with me. Couldn’t have served yourself up better, little bro. You’re gonna feel so sweet and tight when I—”
“Sh-shut up,” Sam breathed. His hand was shaking, the gun wobbling as he crept down a hallway. Dean had to be bluffing. He wouldn’t really...
“And you’re in heat too. Smells... mmh, delicious. You must be aching for someone to rough you up. I can give you what you need.”
“Th-that’s disgusting, you’re my brother.”
“Just close your eyes and imagine my nice hard alpha cock, big swollen balls ready to blow a load inside you...”
A desperate whimper slipped out of Sam. Dean laughed over the phone.
“Knew you wanted it. Slut.”
“I’ll f-fucking stop you.”
“You’re so desperate to get your ass knotted you’ll even let your brother do it.”
“Nnh—”
“Take your clothes off.” Dean’s voice hardened, a rigid command that made Sam freeze. “Strip down and get on your knees where you belong. Wait there like a good bitch so I can come breed you.”
Sam’s knees wobbled and nearly gave out. His breath came in sharp, hungry gasps.
“...T-try harder than that,” he shot back. He couldn’t keep the tremor out of his voice.
“Heh. Fine, we’ll do this the hard way.” Dean paused. “...Gotta go now, Sammy. You’re getting too close.”
Sam froze. He held his breath, knuckles white on his gun.
“Next time you hear my voice,” Dean breathed, “It’s gonna be panting against your neck.”
The call ended.
Sam’s hand trembled as he put the phone away. His face felt hot, his heart pounding. He sucked in a shaky breath to steady his nerves and kept walking.
Sam rounded the corner. The large, main room of the bunker greeted him, everything in its normal place. Sam advanced carefully into the room, his eyes scanning for movement. Something caught his eye, something that wasn’t in its normal place.
Lying on the table was Dean’s black t-shirt.
Sam’s heart skipped. He could smell the shirt from here. The powerful scent of aroused alpha, hard and ready for breeding, was enough to make Sam throb in his pants. If the shirt was here and if it smelled this—oh god—fresh, then Dean must be nearby. Sam swallowed and approached the table cautiously, holding his gun out as if afraid the shirt would attack him. The smell was already assaulting his body, wearing down his resistance.
Every inch of Sam screamed for a deep lungful of that smell.
Sam bit his lip guiltily. He turned in a quick circle, scanning the large room. He listened. All was still and quiet. Before he could think better, Sam grabbed the dark shirt off the table and pressed it to his face, closing his eyes and taking a deep, deep breath.
A shameless moan spilled out of him, his whole body shuddering. His cock leaked in his jeans, his hole clenching, desperate to be stuffed. For a moment, the smell was so overpowering that Sam’s head spun, drunk on the desire for a powerful mate to bend him over and ravage him. His mind swum with images of rippling muscle and thick, dripping cocks, demanding hands and heavy balls, stubble scraping his neck as teeth dug into his skin.
Sam pulled the shirt away from his face with a gasp, his chest heaving. His whole body felt hot. He shouldn’t have done that, he could barely see straight.
If Dean found him like this, he’d—he’d—
A powerful hand grabbed Sam by the throat, pulling him back against a hot, firm body. Sam sucked in a gasp, going stiff in the dominating hold as he felt Dean panting against his neck.
“Got you, little brother,” Dean breathed. His hard cock was a rigid press against Sam’s ass. “You ready to play nice yet?”
Sam trembled in Dean’s hold. His instincts screamed at him to twist away, to fight back, but his body wouldn’t listen. The firm, authoritative hand on his throat felt too good. He tried to summon up words of resistance, but they turned into a whine when Dean squeezed his neck.
“On your knees, slut.”
“Aah—” Sam shivered when Dean’s free hand grabbed him between the legs, hungry and possessive. His gun lowered slowly, wobbling barrel pointed at the floor.
Dean growled in Sam’s ear, squeezing his throat again and choking off his moans. “I said get on your fucking knees.”
Sam thumped to the floor, the gun falling from his hand with a clatter. He panted, whimpering when Dean grabbed a handful of his hair.
“Heh. Much better.” Dean paced around Sam’s submissive body, stopping in front of him. Sam gulped as he looked up. The bulge in Dean’s pants was huge, a thick hot ridge that made Sam’s mouth water. Dean was bare from the waist up, wearing only sweat and a smug, cocky grin. He tugged on Sam’s hair.
“Nnh—” Sam pressed his hands against Dean’s firm thighs, but couldn’t push him away. Every shallow breath sucked that smell into his lungs, hot and heavy and dominating, melting his resistance. The large bulge in Dean’s jeans was right in front of his face. Dean chuckled, undoing his belt.
“Ready to put that mouth to use?”
Sam nearly panted as Dean’s rough hands opened his pants. “Y-you fucking bastard—”
Dean’s thick cock flopped out of his jeans, nearly hitting Sam in the face. It was so close that Sam’s breath steamed on the half-hard length. He had no idea Dean was this hung. The shaft was thick and veiny, a flushed slit poking out through a sheath of foreskin. The fat head was thicker than the shaft, and the knot at the base was thicker still.
The scent coming off it would have knocked Sam off his feet if he hadn’t already been kneeling.
“Go on, don’t be shy.” Dean dragged his cock across Sam’s cheek, leaving a slick smear of precome. Sam gasped when the hot slit dragged across his lips. “Open up, bitch.”
Sam panted against Dean’s cock. Despite himself, his mouth was hanging open, his tongue out, ready for his brother’s dick. Dean’s grip was firm on Sam’s hair, pinning him in place.
“Heh.” Dean pressed his thick cock head against Sam’s waiting tongue, and Sam shuddered at the intoxicating taste. “There’s a good slut.” Dean yanked on Sam’s hair, burying himself in his brother’s mouth in one thrust. “Now suck if you don’t wanna choke on it.”
Sam groaned, his eyes rolling. He was already sucking his brother’s cock by reflex, gripping Dean’s thighs instead of trying to push him away, bobbing his head up and down the thick shaft. Dean tasted like alpha, like power and muscle and everything that an omega like Sam was built to serve.
Dean’s hips rolled, his cock pushing down Sam’s throat, stuffing him. Sam shuddered and whined around his brother’s thick cock, Dean’s hands pinning him in place as his throat was slowly fucked, denim brushing Sam’s chin on each deep thrust. His cock throbbed in his pants.
“You look like such a slut, Sammy,” Dean taunted, yanking on Sam’s hair to force his face up. He pumped his cock slowly into Sam’s willing throat, buried nearly to the balls. “You don’t even care that your brother’s the one fucking you, do you? So long as you’ve got a big tough alpha to fill your holes.” He dragged his cock out of Sam’s throat slowly, leaving him gasping for air when it finally slipped past his lips. “Want me to stop?”
“You s-son of a bitch,” Sam panted, Dean’s cock bumping his lips. A string of saliva and precome trailed between his fucked mouth and his brother’s thick cock. He was so hard he was leaking in his pants, leaving a wet stain on his jeans. He needed something in his ass, he couldn’t take it...
Dean tsked. “Beg me for it.”
“F-fuck you.”
Dean pressed his wet cock against Sam’s cheek. Sam whined, shivering, his ass clenching around nothing. He wanted a cock so bad it was making him dizzy, and Dean knew it.
“Try again.”
“Y-you fucker—”
“Beg for your brother’s big fat alpha cock in your needy hole.”
“Aah—” With a frantic whine, Sam tried to seal his mouth over Dean’s cock again, but his brother’s firm hand held him back. He panted against the thick shaft, his eyes pleading. “D-Dean—”
“Beg me.”
“Nnnh!” Sam whined desperately, his whole body shaking. “...F-fuck me,” he whimpered.
“Sorry, what was that?”
Sam nearly sobbed. “F-fuck me, please!”
Dean groaned, low and pleased. He threw Sam to the floor face-first. Sam caught his breath against the hardwood as he heard Dean stepping over him.
“That’s better. You just needed someone to show you your place.”
The hand was back in his hair, yanking hard enough for Sam to gasp.
“Ass in the air,” Dean ordered.
Sam’s body complied by instinct, arching his back, ready for an alpha’s breeding. Dean’s hand swatted firmly across Sam’s ass, drawing a helpless moan from him. Sam couldn’t even bring himself to curse his brother. The need to mate, to submit, was overpowering.
“I love a good, slutty omega. You’re almost too easy.” Dean grabbed Sam’s jeans, dragging them down, exposing his soft, round ass inch by inch. “Mmmh fuck, that’s a real prize. You don’t give this up often, do you, Sammy?”
Sam swallowed hard when he felt his brother’s hand splay over his bare ass, squeezing. The jeans stopped just under the curve of his ass, leaving the soft cheeks and his tight hole exposed.
“My picky little brother, teasing everyone with this sweet plump ass and not letting anyone pound it.” Dean growled when his thumb brushed Sam’s tight, desperate hole. “Bet your ass is out of practice. Gonna be a tight fit.”
“You b-bastard,” Sam spat breathlessly. He shuddered when he felt Dean’s cock fall against his ass, hard and heavy. “Oh g-god—”
“Not so picky now.” Dean pressed his thick, wet cockhead against Sam’s hole. “You’d let anyone fuck you right now, wouldn’t you?”
“I’ll f-fucking kill you for this,” Sam threatened. His words were too shaky and breathless to have any sting.
Dean laughed and gave Sam a firm spank, hard enough to draw a yelp from him and make his cock jump. He felt his brother’s thick cock push against his ass, and with an embarrassed whimper he pushed back against it, his unpracticed hole starting to stretch. He could feel Dean’s cock twitch, feel an eager drizzle of precome against his asshole.
“Oh Sammy, you won’t even be walking when I’m done with you.”
Dean’s big hands grabbed Sam’s hips, holding him in place as thick cock pushed. Sam groaned as that thick head began to force his hole open, giving him the stretch he needed, stuffing him so full—
“C’mon, baby, loosen up that ass.”
“A-ah—” Sam gasped and his cock throbbed when Dean’s hips rolled and his cockhead popped inside. “Aaah!”
“Mmmh.” Dean gave Sam another teasing spank, making his ass bounce. “That’s better. Tight little hole practically sucked me inside.”
“D-Dean—” Sam choked when his brother thrust, his dick sliding effortlessly deeper, plunging inch after inch into his ass. He could feel that thick cockhead sinking deep into his belly, filling him up, stretching him out. “A-ah, Dean!”
The thick swell of Dean’s knot pressed against Sam’s stuffed hole. Sam’s head was spinning, his knees shaking with the satisfaction of having an alpha’s cock buried inside him. He squeezed around his brother’s cock, panting shamelessly as Dean rutted him deep. He could hear Dean’s smug snicker, feel a patronizing slap against his ass, and all he could do was moan.
“Looks like you know your place now, baby bro.” Dean growled and leaned over Sam to pant in his neck, his fingers digging into Sam’s hips to hold him in place. He thrust in hard, his knot pressing firmly against Sam’s abused hole. “You’re gonna serve me like this whenever I want it. Got it?”
“Y-yes—” Sam whined, feeling his brother’s hips bump his ass with each deep thrust. “Y-yes, please—”
Dean’s hand wrapped around Sam’s neck, squeezing just shy of too hard. His knot pressed hard, forcing Sam’s tight hole open. “Knew you’d spread your legs for your brother. Can’t control yourself, can you?”
The knot slipped inside, and Sam whined through the tight grip on his neck. He could feel the full, hot, throbbing length of his brother’s dick inside him. Dean rolled his hips, shifting his knot, and Sam cried out.
“Mmmh, tight,” Dean groaned, panting like an animal. He dragged his hips back slowly, his thick knot stretching out Sam’s hole again until Sam was shaking and whining under him. “We’re gonna fix that, aren’t we?”
The knot slipped out, and Dean pushed it back in. Desperate, broken moans slipped from Sam’s mouth as his brother knot-fucked him. His cock was swollen and bobbing between his legs with each thrust. Dean’s hand slipped off of Sam’s neck suddenly and grabbed his hair, shoving his face to the floor. Sam shouted against the wooden boards as his brother pounded him. He couldn’t take it, his whole body needed this—
Sam screamed against the floor as he came, clenching down around his brother’s knot, his own cock spurting untouched across the floor. Dean’s pace never slowed.
“That’s it, slut,” Dean panted. His balls slapped Sam’s thighs on each deep thrust, his knot plunging in and out of Sam’s fucked-pink hole. “Mmh, gonna breed you so good—”
Dean snarled and his hand twisted in Sam’s hair as he thrust deep, his thick cock spilling. Sam moaned against the floor as he felt pulse after pulse of come pump into him, slathering his insides and making them tingle. He could feel it filling him up, satisfying his heat and leaving him sleepy and pliant. Dean let out a pleased groan and dragged his knot out, letting it pop free of Sam’s ass before pushing it back in, forcing out a squirt of come that dripped down Sam’s leg.
“Mmmh, that’s fuckin’ good...”
Finally, Dean dragged his cock out, inch after sloppy wet inch. Sam panted against the floor, his eyes hazy. He felt full and swollen with his brother’s come, satisfied and bred. He groaned when Dean’s thick cockhead finally slipped free, lying against his thoroughly fucked ass. Come dripped out of Sam’s loose hole, trickling down his leg.
Dean chuckled and gave Sam’s ass a swat. “Now that’s how a bitch should look. Ass in the air and full of my come.”
Sam shivered, his spent cock twitching at the words. His dizzy mind vaguely registered that he was supposed to stop his demon brother, not satisfy him. Arms shaking, Sam pulled himself to his hands and knees. His whole body was tingling with the aphrodisiac effect of alpha come in his belly.
Dean’s footsteps thumped as he stood up and strode across the floor. Sam caught his breath, his hair hanging in his face. He had to focus. He had to find his gun, find a way to...
A dominating hand fisted in his hair. Sam’s face was forced up.
Dean stood over him, smirking, his come-dripping cock hanging out of his jeans. Sam looked up at it helplessly as a creamy drip gathered on the thick head.
“Clean me up,” Dean ordered with a smirk.
The resistance in Sam’s mind clicked off. He sucked his brother’s sloppy cock into his mouth with a shuddering moan.
