Dean ate him.
That was the thought running through Sam's head in an insistent, hellish loop. He hadn't seen Dean eat the security guard, but he had heard it. The feeding had been atrocious: a dragging, gulping sound followed by Dean's low murmur of ecstasy. Now, Dean was covering his back, pressing hot kisses against his neck, nibbling the flesh between his monstrous teeth. Sam now understood that Dean's fangs were like real snakes: venomous. He mumbled a curse through the gag over his lips.
"You ready for your reward, little brother?" Dean whispered hotly against his neck, licking. Sam ground his teeth together, a stab of dread wedging its way into his throat. He wanted to be anywhere but under Dean's hands. Dean caressed his ass. "After all, you were so good for me."
Sam resisted squeezing his eyes shut. If Dean was going to attack him, he needed to stay strong and defend himself, even if Dean succeeded in getting what he so obviously wanted. With his hands pressed between his back and Dean's shirt, attempting to break his bonds would be frivolous. Instead, Sam rubbed his face against the concrete, trying to dislodge his gag.
Dean hissed, "You're gonna love this, Sammy. I can feel it. It's pressing against my insides. I want you so bad. It wants you so bad."
Sam's brow furrowed. What was Dean talking about? What was pressing against his insides? What was it?
Suddenly, Dean gripped Sam's shoulders and snatched him off the ground. Sam shouted into his gag, mostly from surprise, but also from a scuttling fear zipping through his veins. Dean maneuvered Sam into his arms, carrying him bridal style, one arm slung under his knees, the other under his shoulders. Sam met Dean's eyes. They glowed a rich emerald green in the low light, cat-like and predatory. A sensual smile bent on Dean's plush mouth. It was unsettling especially with the dried blood speckling his pale chin. Sam grimaced when Dean pressed a kiss to his forehead.
Without another word, Dean slithered over to the four-poster bed covered with billowy white sheets. Sam squirmed in Dean's hold, but Dean held onto him tighter, using his shoulders to push back a section of the sheets. He laid Sam down onto the soft mattress. The comforter smelled distinctly of lavender. Sam stared at the white canopy, his heart thudding against his ribcage. From the corner of his eye, Sam saw Dean slither backward. His silhouette danced against the sheets, dark and quick. There was a sudden riiiipppp. Dean clawed them down, tearing them from their posts and, like ghosts, the fabric flapped to the concrete. Sam wiggled against the comforter. The mattress jarred.
Dean chuckled, gripping his boot, slipping his fingers up his pant leg, and caressing his ankle with the pad of one thumb. Sam peered down at Dean. Below Dean's human half, his massive serpentine bottom stretched out across the room, unbelievably plump and long. Sam's eyes darted over the distinct bulge in the middle of the tail, his fingers trembling with disgust and terror.
"Sammy, look at me," Dean purred.
Dean's expression was consumed with lust. It was an expression so like hunger that Sam tensed on the bed. Dean licked his bottom lip before a satisfied smirk curled on his mouth. "You look so good like this, all tied up. Might just have to keep you like this forever."
Sam glared daggers at Dean, his face flushing red. He yelled obscenities through his gag, jerking a few inches off the bed.
Dean chuckled, "Oh, I'm just kidding. Calm down." Dean crawled up, his movements languid and cat-like, slowly making his way up Sam's body. Dean grasped between Sam and the mattress, separating the ropes with quick, practiced movements. Once free, Sam ignored his throbbing wrists and tugged down his gag. The fabric settled around his throat. Dean tossed the ropes away. They landed with a splat in a puddle somewhere in the dark.
"Get off me!" Sam shouted, shoving Dean's broad shoulders. Lighting quick, Dean snatched his forearms, pinning him to the bed. "Get off!"
Dean smiled down at him, his eyes half-lidden, "Settle down. You'll pull something." His fingers pressed harder. Sam knew if he survived this, he'd have bruises on his arms in the shape of his brother's hands tomorrow.
Sam spat, "Get the fuck off me, Dean." He writhed underneath his brother, bucking up. But Dean's hands were like metal clamps: immoveable. "I'm serious. Whatever you're thinking of doing, no."
Dean leaned down so his face hovered inches from Sam's. Sam twisted his face away just in time. The kiss meant for his mouth landed on his cheek. He clenched his knuckles, grimacing when Dean's lips dragged down his cheek to rest underneath his jawline.
"Stop resisting. You know you want it just as much as I do." Dean hissed, nuzzling underneath his chin. "I'm gonna make you feel so good."
"Dean, this isn't you. This isn't you, man. If you were in your right mind, you'd never do this." Sam croaked, wincing when Dean nibbled the protruding tendon on his throat.
Dean growled, releasing one of Sam's arms and grabbing his groin. Dean's fingers clamped down, fondling his cock through his shorts. Despite the fact one of his arms were free, Sam froze at the touch, the urge to beg rising hot and heavy in his throat, only terror clamping his jaw shut.
"Mmmm, you're getting hard for me," Dean moaned, licking into Sam's ear. And, despite everything, Sam felt himself growing hard. Sam looked at his brother's face. Dean's eyes were heated, unapologetically wild. Dean smirked. Sam prepared himself to pull back his fist and knock his brother in the mouth. Dean suddenly let go of his groin with a low groan, pushing up. Dean's head tilted down, looking at something between them.
Sam's jaw fell open.
Below the space where flesh melted into the start of Dean's horrific serpentine half, something bulged grotesquely from his scales. Then, the protuberance popped out of a hidden slit under Dean's belly.
It was Dean's cock.
Sam stared at Dean's monster member. It was like no cock Sam had ever seen before. Before, Dean's dick had been thick, veiny, and a blushing pink, the cockhead only slightly fatter than the length. Now Dean's member was at least eight inches long, twitching where it slithered out of Dean's masculine slit. The length of the cock was wide, a dark red, like dried blood. Veins, blue and purple, coiled around the shaft. His cockhead was fat, solid black. The whole appendage was soaked with a sheen of sticky substance. Self-lubricating, Sam expected. As the thought occurred, a clear, tacky fluid dripped from the slit in the head, landing on Sam's belly. The head hovered an inch above Sam's shirt. Dean's monster cock was so huge that the recipient of that member would be stuffed full. To think Dean ached to impale him with that sent Sam into a panic.
"Dean, no." Sam tried to move up and out of Dean's embrace, but Dean pounced, heaving Sam onto his belly. With his face smashed into the pillow, Dean's clawed fingers skimmed down his shirt and quickly found his pants. Dean gripped the limited space between the fabric and his skin and pulled. Sam felt cool air on his bare flesh. Goosebumps formed on his arms. Sam trembled.
They had been captured by the monster they were hunting. The monster turned Dean and fled. Dean had just eaten a dude and now Dean was going to rape him. How could this night get any worse?
Sam felt Dean tear off his pants, tugging the fabric down to his ankles; Dean ripped off the constricting ropes. Sam's stomach twisted with grief and fear and betrayal. He kept telling himself that it wasn't Dean grasping his bare buttocks in his clawed hands, it was his current condition. It wasn't his Dean snarling at him, it was the evil, sadistic Naga that had taken his place.
"Dean, stop!" Sam gasped, pushing up. Dean grabbed his hips, yanking him back down.
"Hush," Dean purred. "Just relax." Dean stroked under Sam's shirt, jerking at the material. They tussled for awhile: Dean trying to pull his shirt off, Sam trying to keep his shirt on, until Dean managed to wrench the offending article of clothing over Sam's head, hurling it off the bed to land beside his pants.
"Look at you," Dean breathed, caressing Sam's hip. "You're so beautiful."
Sam was bare. Naked. Terrified.
Sam scrambled up the bed and managed to press against the headboard, but Dean snatched his legs, dragging him back down the mattress. With a hand on his lower back, Dean shoved Sam onto his stomach, gripping his left hip in his claws, careful not to cut Sam's delicate skin. Panting, Sam stared at the shadows dancing across the wall, the flickering candlelight. His heart felt amplified against the mattress.
Dean's hand came into view. He smoothed his fingers across Sam's forehead, swiping away his sweaty locks. His hair fell back into place. Sam fisted the sheets. His knuckles turned white and bloodless. Dean kissed his shoulder. "So beautiful." He petted his back. "You smell so good."
"Dean, please." Sam whispered. "Don't."
Dean purred. "You smell so good and fuckable, Sammy."
Sam buried his face into the pillow, biting his lower lip so hard that pinpricks of blood burst from the soft tissue. Dean slithered down his body and reached for his ass, pulling apart his cheeks. Sam wanted to bury his face deeper into the pillow, disappear completely. Dean peered down at Sam's tight, dry hole. He squeezed the supple mounds of flesh, leaned over, and pushed his face down, licking tentatively at his entrance. Sam choked.
Dean swiped his tongue up his pucker again, causing Sam to go limp in his grasp. Tears formed in Sam's eyes, spilling onto the pillow. Sam wept. This was really it. Dean was going to lick him open and then have his way with him. And Sam could do nothing to stop him. Was Dean going to keep him as his own personal blow-up doll, bringing him to bed whenever his cock demanded? Or was Dean going to eat him all up, just like he'd done that poor security guard?
Either way, Sam knew his brother-the brother he'd loved, trusted, relied on-was dead. Sam lost himself in his own grief and fear and misery, distancing his mind from the swipe of his sibling's wet tongue up the crack of his ass, Dean's lustful utterances, and his powerful hands kneading his hips. That's why when Dean stopped and pulled back, Sam didn't realize he'd stopped until Dean was hauling him onto his back.
"Sammy?" Dean's voice was soft, almost pained.
Sam's eyes fluttered open, blurry from his tears. Dean's expression was worried, tentative. The look was so like human Dean that Sam cried harder. Dean's hands hovered over Sam's shoulders. Yearning, but not touching.
"Dean," Sam gasped. "Stop. I-I don't want it. Please."
Dean stiffened, his eyes still feral and hungry, but his face twisting into something like pain. Dean tore away from Sam. He pushed away from the bed, snarling under his breath. Sam froze, eyes tracking Dean's movement. Dean's back was a line of tension, his hands balled into fists. He slithered forward, pausing in front of the slave pen. The slaves' eyes all turned to their new master, faces twisted in terror. Sam did not want to see the expression on Dean's face to garner such a reaction.
"Pull your clothes back on," Dean snarled. Sam didn't need to be told twice. With trembling legs, he slid off the bed, bend down, and yanked his clothes back on. Sam's fingers trembled on his belt buckle. What had happened? Why had Dean changed his mind?
A sharp clang! tore Sam away from his thoughts. Sam saw Dean tear off the lock to the cage, rapidly slither inside, and pull out a man at random. The remaining captives scrambled to one side of the cage as Dean slammed the door shut. Although the man trembled with fear, he did not try to worm his way out of Dean's grasp. Instead, he allowed himself to be dragged to the bed. The captive was thin, medium-build, and with a hair-cut that resembled Sam's: overgrown and boyish. Dean tossed him carelessly onto the bed and climbed over him.
"What are you doing?" Sam said, taking a shuffling step back.
"I'm not gonna fuck you if you don't want it, Sammy. But if I don't fuck someone, I won't be able to control myself." Dean snarled, hauling the unresisting slave onto his stomach and shoving a pillow underneath his slim hips. The captive's ass was presented high in the air, bruised. Dean blanketed his back, his cock swinging, precum dripping down the crack of his ass.
"Do you know what you do to me?" Dean's voice sounded desperate, crazed. Sam stared into Dean's animalistic eyes, caught like a mouse. Dean's fists clenched around the sheets. Underneath him, the slave whimpered where the warm, musky fluid drippled down his lower back.
Sam shook his head. "Dean, I-"
"Do you have any idea how hard it is for me to not just take you?" Dean snarled. Sam adverted his eyes, trying to keep his breathing under control. He didn't want to say the wrong thing and cause Dean to snap. "That's what I thought. So just, Jesus, just shut up and sit down."
Sam's legs collapsed and he sat on the bed, a mere foot from where Dean blanketed the slave. Sam's stomach roiled in terror. Dean tore his eyes from Sam and grabbed the slave's hand, wrenching his wrist back and rubbing the captive's fingers around his shaft, coating the digits in the tacky clear fluid.
"Prep yourself," Dean ordered, releasing him. The slave adverted his eyes, pushing up. Dean maneuvered back with a low hiss, watching the slave obey. The man's fingers found his puckered hole. The captive rubbed his entrance, before diving in, separating the tight, delicate muscle. He fingered himself slowly, gaining another digit after a minute. Bile rose in Sam's throat. He wanted to desperately tear his eyes away from the man, but he couldn't. Dean pawed at the captive's waist, swiping down his hip. The tip of Dean's tail twitched.
"That's it." Dean growled. "Deeper. You're going to need to be stretched if you're gonna take all of me." Dean's snake half trembled in excitement, his cock dripping precum in steady intervals now.
The captive whimpered softly, pushing his fingers deeper into his tight tunnel. Sam watched the act with a mix of disgust and pity. The man wasn't even fighting back. In fact, he seemed to be used to the act of opening himself up. Realization crossed Sam's features. Perhaps that is what the other Naga meant by needs: these men were sex slaves. The thought of a monster owning a human for that purpose until the human was no longer feasible or the monster grew bored of them? Revolting. Absolutely revolting.
Dean's eyes shifted from the slave to Sam, the heat smoldering. Sam turned his gaze away, overwhelmed by Dean's lust. Dean didn't respond. Instead, he tore his eyes away from Sam and said, "That's enough. On your hands and knees."
The man jerked his fingers out and rolled onto his belly, pushing up onto his hands and knees, hovering over the pillow. Sam's heart slammed into his throat, his palms becoming hot and itchy. Should he try running since Dean was going to be occupied? Or should he stay, try to reason with Dean?
Dean grabbed his cock and guided it towards the slave's hole. He pressed in, feeding his massive length an inch at a time, until the slave was stuffed full. From his angle, Sam could see a bulge in the prisoner's belly. Dean moaned, holding himself inside. The slave gasped softly, fingers wrenching around the bedspread. Dean tilted his hips back, his snake half sliding gracefully, pulling his cock halfway out, before he slammed back in. The slave grunted. Dean moaned, closing his eyes. He fucked into him again. In and out. In and out. In and out. With each thrust inside, the impact made a loud squelch!
Sam watched in horror. The slave, accustomed to the act, took Dean's cock with no grunts of pain or expression of discomfort, even as his belly bulged with each dive into his tight hole. Dean grabbed onto the captive's hips, claws biting into his tender flesh. Still, the slave, with his head down, did not complain. Sam found himself encapsulated with each rough thrust, with each grunt, with each soft whimper.
Suddenly, Dean opened his eyes and peered at Sam. Dean impaled the slave's hole on his member. Faster, faster, faster.
"Come here." Dean growled, holding out his arm. His fingertips were inches from Sam's chest.
Sam shook his head, about to leap up and away from the bed. "No."
"I'm not gonna hurt you, just come here." Dean bit through clenched teeth. Sam's shoulders deflated and he closed the distance between them. Dean grabbed his face, caressing his cheek.
"Sammy," Dean grunted, his dick thrusting in and out of the slave's abused entrance with a punishing speed. "Fuck, fuck, fuck."
Sam's stomach roiled with disgust. No doubt in his mind did Sam believe Dean was imagining him underneath him. Dean dragged Sam forward and pressed a heated kiss to his lips.
With one more powerful thrust, Dean climaxed.
