Dean found out quickly that Sam's pregnancy was a little different than a regular human's. For one, their offspring's development was accelerated. A week after their impromptu love making, Dean would say that Sam's belly had expanded out by at least two inches. Sam's skin was practically glowing; his appetite had increased. It hadn't been his craving for food that kept Dean busy, but Sam's insatiable libido. Sam's hankering for Dean's member was as ferocious as his yearning for thick, juicy hamburgers and salty, crispy fried chicken.
Whatever health focused diet Sam had religiously adopted before his brother's transformation had deteriorated into stuffing his face with enough food to make even Dean turn a little green. Whatever the little ones nestled inside Sam wanted, Sam did not withhold. If they craved meat, which his body was quickly realizing, Sam would give it to them, even if the ground beef stained his teeth pink and his throat lurched with every mouthful.
All the while, Sam couldn't keep his hands off Dean. It wasn't just his brother's serpentine cock-which Dean made it his personal mission to rail him on every available surface of the burrow-that Sam wanted, but his touch. Sam had started to cling to him, nuzzling against Dean whenever he was in touching distance. At first, Dean was annoyed by it. Although he adored Sam with all his being, a little personal space was desperately needed. But whenever he saw how upset Sam would become when he attempted to distance himself, Dean quickly acclimated to the new status quo. No place was off limits on his body if it was Sam's hands seeking him out.
Except his snake half.
Sam could stroke and caress his Naga half all he wanted, but the second he tried to climb into his coils, Dean panicked. Although Dean told himself he was the master of his relatively new body, a small part of him was frightened of his snake half. He had seen what his mind could turn into when he was hungry and he didn't want to risk accidently hurting Sam by squeezing him too hard. When Dean plucked Sam out from his coils, Sam protested, saying he just wanted to be close to him. But Dean did not budge. He would not risk constricting Sam.
But one night not long after, Dean woke suddenly to a strange sensation brushing against his lower half. He peered down to find Sam nestled in his coils, one arm thrown over the thickest portion of his scales, his cheek pressed against the scaly, powerful muscles. Panicked and assuming he'd unconsciously coiled around his brother, Dean had loosened his grip. It was only when Sam's eyes fluttered open and he glowered at Dean did Dean realize Sam had climbed into his coils on purpose.
"What the hell, Sam?" Dean hissed. "I could kill you!"
Sam rubbed his eyes and rose from Dean's unwinding scales. His hair stuck up at odd angles, a tangled bush of bed head.
"Don't you ever do that again," Dean growled, his claws prickling at the bedsheets.
Sam climbed over his snake half and glared. "You won't hurt me."
"I don't know that."
"I trust you," Sam said, climbing onto the bed and crawling towards Dean. "Why can't you trust yourself?"
Sam reached out and grasped the side of Dean's face, rubbing his thumb against his brother's cheekbone. Dean scowled. "Just don't do it again, okay?"
Sam glared, but pressed a kiss against Dean's mouth, anyway. Just as Dean pressed into the kiss, Sam tore his lips away, staring into his eyes with a look of potent frustration.
"We gonna fight or make out? 'Cause I'm getting some real mixed signals here." Dean said, reaching out to stroke Sam's side.
"I like you being wrapped around me," Sam explained. "It makes me feel safe."
"Well, it makes me nervous, dude. So let's not." Dean retorted.
Sam's eyes flickered over his face. Once he realized Dean wasn't going to budge on the topic, Sam let out of frustrated huff and nuzzled into Dean's chest without another word.
Just as Sam's body was changing, Dean realized his was, too. It started as a strange tightening sensation in his scales. After a day, Dean awoke to a grayish-white sheen over his lower half, enveloping his bright orange and red scales. The sheen even covered his slit. He had a sinking feeling that even if he did get excited, his cock could not come out.
It was Sam who accurately diagnosed Dean's sudden condition. Sam: always the brains of the operation.
"I think you're shedding," Sam said, gently prodding Dean's scales. Dean hissed, baring his teeth, as pain radiated from Sam's tentative touch. Sam was crouched over his lower half and Dean had to be very, very still. His body ached to curl in on itself.
"What does that mean?" Dean asked through gritted teeth.
Sam blinked, getting up. With one hand on his lower back, his other hand went to the gentle swell of his belly. He rubbed his abdomen. "Did you ever take Biology? Snakes shed their skins to get bigger."
"Bigger?" Dean said, and the idea wasn't so bad. If he were bigger he'd be even more suited to protect Sam and the babies. "But why does it hurt so bad?"
Sam frowned. "I don't know. Maybe it hurts snakes to shed their skins."
Sam was right. After a few days, the pain had become unbearable. His lower half was a grayish-white. The dead skin would not come off, no matter how many times Dean scraped against the sewer walls. What was worse, he couldn't even eat. The flailing, panicked prostitute the slaves had picked up was forced to be gagged and tied in the cage. His pain was so intense it buried his bruising hunger. Dean promised himself that after his skin peeled, he'd indulge in her.
Sam suggested that maybe he needed water to shed his skin, something Dean had never thought about. Despite his pain, Dean blanched at the idea of leaving Sam alone.
"I can't, Sam. Not after what those demons did. No way," Dean growled. He was lying down on the mattress, a wet washcloth covering his forehead, already drenched with sweat. Sam sat beside him, long legs dangling over the edge of the bed, his hand wrapped around Dean's tight knuckles.
"I'll go with you," Sam suggested. "You said you found a tunnel that lead out into a forest. You said there was a river; that there were no people around."
Dean swallowed thickly, "I don't want you exposed, man. Those woods. I've explored them. They're dangerous."
Sam's eyebrows furrowed, "Dean, you'd be the most dangerous thing out there."
"Sammy-"
Sam's expression soured: "I know you don't want me to leave the room, but with you, I'll be safe. I know you'll protect me."
Dean squeezed his eyes shut. The anguish radiating from his tight skin was overwhelming. It felt like he was being squeezed to the point of oblivion. His brother was right: he would protect him to the death. He had found a river. The visceral image of the cool, clear water almost made Dean moan. He could almost taste the relief at the back of his throat. To dive in would be orgasmic.
But then there had been the fragrance on the breeze, the one that Dean could not make out. Whatever had been that smell that had sent his instincts on edge, he did not want to relive it. But maybe he'd have to. Maybe it was either that or death.
"Okay," Dean said finally. "We'll go."
Dean could hardly slither through the tunnel that led to the thickly wooded area. Sam walked beside him. Underneath him felt like a bed of razorblades. Every tug and clench of his muscles felt like acid being stabbed into his system. Sam was close to his side and before Dean even realized it, they were at the mouth of the tunnel.
Sam stared at the wide, open maw, at the dusky light spilling forth. It had to be late evening. Evening that was rapidly bleeding into night. Even so, after only being subjected to candle light for so long, Sam's eyes ached. A slight breeze whistled inside. He breathed deeply. The air was so clean, so crisp.
"Go first," Dean said through gritted teeth. "I'll be right behind."
Sam hesitated only a moment, before he forced his legs to move. He walked out of the tunnel and straight into the woods. He stopped and stared. It was like stepping into a whole new world. Stripped away from a tomb of metal and low, purring vibration, was a peaceful, rich forest. Dean, close behind, slithered out of the tunnel, grimacing as he banged the side of his tail against the rusted frame.
"Sammy?" Dean asked through a grimace, staring at Sam's still back.
"Just give me a sec." Sam breathed.
Sam closed his eyes and listened, savoring his first taste of the outside world since Dean's transformation. Winds slipping through underbrush. The flutter of unseen wings. Dean's labored breathing beside him. He inhaled, letting in deep lungfuls of delicious air. Rich earth. Rotting leaves. Tree sap. Wild, hidden things. Growth. Greenery. He could feel the dying heat of the setting sun lick stripes of light onto his face.
He tilted his head back. Wind grabbed his hair and shoved it back from his forehead. Emerged in a world so fresh and crisp, it was only then Sam realized how bad he stunk. He wrinkled his nose and peeled his eyes open.
Sam glanced over his shoulder, "Lead the way."
Dean slithered through the forest, his jaw clenched tight and his forehead slick with sweat. Sam followed close behind. His boots tramped over bumpy roots and wet leaves, pine needles and fallen logs. Tall, shadowed trees stretched up like arrows to the sky. Above them, white crowned sparrows fluttered from tree branch to tree branch, their black and white heads cocking to the side, inky black eyes observing them. After stepping over another log, a twinge of pain burst from Sam's lower back. Sam grasped his back, rubbing the tight knot. He held his hand there and placed his other hand on his swollen belly, trying to ignore the aches and pains that grew worse the deeper into the forest they traversed.
The sun was rapidly setting, casting the sky in brilliant shades of salmon pink and baby blue. The further they moved, the gradually darker it got. By the time they arrived at the river, the sun had set. Above them stars shone as sugar spilled over black marble. The moon, fat and full, shone down, delivering the landscape into a blurred, simple hue. The wild river before them twisted and flowed. The edge of the river was made up of small stones, the color of bleached bones. Made a dark blue by the lack of light, the river burbled and murmured in Sam's ears. Sam squinted as Dean slithered rapidly past him, overwhelmed with his need for release. Dean dived into the water with a loud splash! His lower half dipped inside, forming great ripples that lunged towards the edge of the water.
Dean's upper body resurfaced a second later, his lower body half peaking out of the water like some strange reptilian water monster. Patches of old skin, white and wide, peeled from his Naga half in heavy clumps. Dean bent over and whipped his tail up, pawing at his loose skin, rivets of water leaking down his face, clinging to his facial hair. His expression was one of relief and bliss.
Sam's boots crunched as he walked to the edge of the water. He sat down, stripped his shoes, socks, and shirt, watching Dean take off his old skin, revealing vibrate patterns of orange and red, intricately patterned and shining with newness. The dead skin floated on top of the water like tattered blankets.
For a second, Sam thought how easy it would be to run. To flee from Dean. To find humanity. But just as the thought occurred, a twinge of guilt cut into Sam's chest, followed by the brighter sting of how slow and clumsy he'd gotten. He wouldn't get far, not with his round belly or aching body. He grasped his belt and unclasped it, pulled down his pants, and stepped out of them.
He let out a breath and moved towards the water's edge. When his toes touched the water, he shivered not with cold, but with relief. The heat of the day had warmed the water to a lukewarm temperature. Sam walked into the river. The water was halfway up to his chest when Dean noticed him. Sam closed his eyes and dipped below the water.
To think Dean was fast on land was nothing compared to seeing Dean in the water. Without gravity, his tail whipped back and forth, propelling him to Sam in a matter of seconds.
Dean grabbed underneath Sam's armpits and lifted him out. "Sammy, what are you doing?"
Sam grasped Dean's shoulder to steady himself, "Just cleaning myself." Water poured down his face and drippled down his throat. He ran a hand over his face, dispelling the water from his eyes.
Dean pulled back, eyes flickering over Sam's face. He opened his mouth to say something. Perhaps to tell Sam to get out of the water. Perhaps to make a joke. He did not get the chance.
Sam pressed his lips against Dean's. Dean's mouth was warm and soft. Sam slipped his tongue inside, curling it against the sharp edge of one fang, as if balancing that hard edge between safety and danger. Dean could taste their shared air, feel the thud, thud, thud of Sam's racing heartbeat through his wet, tender flesh. Dean grasped the back of his skull, curling his claws into his damp locks. Sam pressed closer, looping one arm around Dean's broad shoulder, clinging to him. Dean clutched at his sides. After a minute, Dean pulled away, mouth pink and used. They bobbed in the water, two souls in the middle of the steady stream. Overhead, an owl let out a low hoo, hoo, hoo before pivoting from the branch and flying away.
"Sammy," Dean whispered, nuzzling Sam's forehead. Dean's eyes glowed in the dark, steady.
"Want you," Sam murmured, dipping his head and kissing underneath Dean's chin and down to the edge of his jaw.
"Again?" Dean teased, even as he shook with barely contained want. "Didn't we just do it a few days ago, before I started shedding?"
"So?" Sam said, cupping his lips across Dean's neck and sucking. Even if Dean's accelerated healing made it so he did not have bruises for long, it wasn't without Sam's effort. "I need you."
Dean moaned, squeezing his eyes shut. He could feel Sam's tummy pressed against him and underneath, Sam's erect cock. It was hard-no, impossible-to deny Sam when his brother was this persistent, this wanting.
"Okay, baby," Dean murmured. Dean wrapped his arms around Sam and guided him out of the water. Sam wrapped his legs around his waist and held on. Dean slithered on shore and placed Sam on the ground.
Under the moonlight, Sam was gorgeous: wet, heavy locks clinging to his broad forehead, his fox-like eyes half-lidden in want, his chest-nipples pink and wet-heaving. Droplets glided down his distended belly. Braced with arms on either side of him, Dean bent down and kissed his stomach. Sam lifted his hand and grabbed the back of his head, nudging him down. Dean smirked, knowing exactly what Sam wanted.
Dean licked his shaft. Small, kitten licks. Teasing. Sam squirmed under him, the muscles in his thighs tightening. His fingers digging into the back of Dean's hair. Dean hissed in pleasure-pain. His claws dug into the stones underneath his palms. Dean's tongue flicked down onto Sam's testicles, curling around the twin balls. Diving closer, Dean took his leathery, hot sack into his mouth, sucking and slurping. Dean's serpentine half shivered back and forth in the water, forming ripples.
Sam's back arched. He moaned, "Ah, Dean."
He pushed ever further, gargling Sam's balls until something hot and wet pressed against his chin. He retracted his mouth and wiped his chin, coming away with a stringy glob of slick.
"Man, you must be excited," Dean purred, making sure Sam was looking at him. Without breaking eye contact, Dean tilted his wrist forward, letting Sam's slick drip to the edge of his pointer and middle finger. Just before the wetness could drip off, Dean raised his fingers to his mouth and sucked his fingers clean. Sam's mouth fell open, his cheeks flushing.
"Mmmm," Dean cooed. "You taste good, Sammy."
Sam grasped Dean's shoulders, pulling him forward until they were pressed chest-to-chest. Sam curled his legs around Dean's waist, kissing his throat and shoulder. Dean pressed a kiss underneath his ear before whispering, "You wanna know how good you taste?"
"Yes," Sam moaned. "Want you."
"Taste like candy, baby." Dean purred, licking Sam's mating claim. Sam shivered.
Dean's cock popped out. Dean pressed his member against Sam's smaller shaft, rocking back and forth. His fat, wet black tip mushed against Sam's pink rod, prodding it to leak. Sam peered down at the space between them. A secret, buried part of him relished in the fact that his bloated tummy nearly hid his cock. Day after day, he was getting plumper with Dean's babies. Sam squeezed his legs around Dean's waist even tighter.
Sam moaned, staring up into Dean's eyes. "Fuck me, Dean. I don't want to be able to walk after you're done with me."
Dean's eyes widened and his mouth fell open into a little O. He paused his thrusts.
Sam broke into a smile. "Your ears...you're blushing, man."
Dean snorted, glancing away. "Me? No way."
"You think I can't talk dirty, too?" Sam said, carting his fingers through Dean's hair.
"Nah, just wasn't expecting it from you, Sammy." Dean said, shrugging.
Sam's brow furrowed. "Why not?"
"Just because."
"Have you met me?" Sam snorted.
Dean ran his fingers through his hair. "You're just so innocent." Dean brushed his fingers over Sam's lips. "So soft and sweet."
Sam unwrapped his legs and shimmied out from under Dean. Dean lifted up, frowning at the look of distain on Sam's face.
"What? Did I say something wrong?" Dean croaked. Sam stood up and peered down at Dean. Water drippled off his legs, splattering the pebbles underneath them.
"On your back," Sam pointed to the empty space to his left. "Now."
"What?" Dean blinked. His tail twitched.
"I said I want you to get on your back. Now." Sam repeated, his expression souring further.
Caught off guard by Sam's authoritative tone, Dean slithered further out of the water and twisted around, laying on his back. He peered up at the sky. The countless stars shimmered and winked in the inky blackness. The moon, pregnant and silver, shown down on them. Dean heard the crunch under Sam's feet and felt his body heat. Sam maneuvered down his body until he was crouched over his cock.
"What are you doing?" Dean raised an eyebrow, looking down. Sam suddenly moved up. An arm flew out.
"Shut up," Sam said sultry, slapping Dean gently across the face.
Dean's eyes widened. Had Sam...just...slapped him?
Sam reached down and grabbed Dean's dick. "Don't talk."
Dean's face flushed a deep red. It was hard to be intimidated by Sam, what with his soft skin and round belly. Not with his delicate, pulsing humanity. But in that moment, staring into Sam's half-lidden hazel eyes, Dean was putty in his hands.
Sam's fingers curled tighter around his dark crimson shaft. He held him there. Dean couldn't move a muscle, not with his cock in Sam's hand. And Sam knew it. Cheeky bastard.
"Sammy," Dean hissed, jaw clenched. "Come on, dude."
Sam tugged. Dean whimpered.
"Your cock's so fat, Dean." Sam whispered, peering down at it. He jerked it up and down, up and down. Painfully slow. "Love it inside me. It's made for me, right?"
Dean groaned, back arching.
"Come on. I asked you a question." Sam practically growled.
"Sammy."
"That is my name. Don't wear it out."
"Fuck."
"Maybe I'll let you, dude." Sam smiled. "If you're nice."
"Always..." Dean gasped. "I'm always...nice."
"Liar." Sam smiled. jerking his member faster, faster, faster. "Now tell me."
"Yes, it's made for you," Dean purred, finding the strength to sit up even when pleasure was stabbing through his system with every tug of Sam's fingers. "Made to fill you up."
"You're gonna be a good daddy, huh?" Sam asked. "Gonna take care of me like you're supposed to?"
"The best. Gonna protect you and the babies. It's, ah, it's my job."
Sam nodded, "You better." He suddenly tore his hand away. Dean hissed, aching for his touch.
Sam shoved his face down. His breath ghosted against Dean's sensitive head. He hesitated just a moment before his jaws unhinged and he cupped his lips around Dean's cockhead. His tongue found his slit and he licked. Lick, lick, lick.
A lightening bolt of shock and toe curling pleasure slammed into Dean's whole body.
"S-Sam," he hissed. Sam began to suck, nursing and hanging on, even as Dean's Naga half quaked and shivered. Drool slipped down his shaft. Sam curled his hand around the base and shoved as much of Dean's cock into his mouth as he could, which wasn't much giving its width and length, but it was enough that Dean was pretty sure he was going to faint. Sam, cheeks bulging, slurped on Dean's cock, bobbing his head up and down. Drool and pre-ejaculation fluid leaked out between Sam's cheeks and his shaft, dripping down his chin and sprinkling onto Dean's stomach. After a couple minutes, Sam popped off his cock, coughing into the crook of his arm. He wiped his flushed mouth with the back of his hand.
"Mmmm, you tasted good." Sam purred, swinging his leg over and crawling up Dean's body.
"Sam, ah." Dean moaned when Sam's body rubbed against his shaft, causing his dick to press upward, becoming trapped between their bodies for a moment before Sam slipped off him. Sam laid on the ground beside Dean for a moment, panting, before he spread his legs. Dean turned his head. Sam turned his head to meet his gaze.
"What are you waiting for?" Sam sighed, a smile curling at the edge of his mouth. "Aren't you gonna fulfill your duty?"
Dean did not have to be told twice. He push upward and lunged over Sam. Sam curled his legs around his waist as Dean shoved his cock into his hole. With one hand on his plump belly and another shoved underneath his back, Dean pounded into him. Sam curled his fingers into Dean's shoulder and the back of his head, body jerking with each delicious, perfect thrust. Midway through fucking, Dean began sucking his throat, causing Sam to turn his head to give him better access.
It was then, somewhere deep in the forest, nestled between shrubs and inky blackness, Sam's caught the flash of golden eyes. Cat-like, golden eyes.
He gasped, heart plunging into his stomach. He blinked. There was nothing. Just the dark trees swaying in the breeze.
"What is it?" Dean's thrusts became sharper, harder. He turned to look where Sam was staring.
Sam blinked, swallowing thickly. He tried to calm his pounding heartbeat. It could've just been a mountain lion. Didn't California have mountain lions?
"I thought I saw something."
"What?"
"Nevermind." Sam shook his head. "It was probably just a tree."
Dean took him at his word. His thrusts got sloppier, rougher, until Dean was shaking in orgasm. Dean's orgasm yanked Sam into his own, his hole clenching greedily around his shaft, his cum squirting up between them, peppering Dean's belly with creamy specks.
For a long time after Dean pulled out, he and Sam laid under the stars, soaking in the fresh air. Sam tried to shake the feeling that something out there had been watching them. That wasn't possible. Dean would've smelled any animals nearby, wouldn't he? He was especially good at scenting humans. Sam's mind played tricks on him sometimes, that was all.
After a while, they dipped back into the water and cleaned each other. Sam pulled his clothes back on, laced his boots, and began to walk back the way they'd come. Slithering beside him, Dean's glowing orbs flickered constantly around them. The walk back to the sewers was less frightening than Sam imagined, even if he was being led by moonlight alone.
It was only when Sam spotted the mouth to the tunnel that he sensed something was wrong.
There was a thing on the ground in front of the tunnel. It was furry. Brown.
It was not moving.
Dean stopped dead in his tracks, whipped his hand out, and grabbed Sam's arm. "Stop."
"What's wrong?"
Dean's eyes darted around. His nostrils flared. "There's that smell again."
"What?"
Dean's blinked and spotted what Sam had already saw. Dean visibly tensed. His voice was monotoned: "Sam, stay behind me."
"What's wrong?"
Dean shook his head slowly, cocking his head to the side as if trying to listen for something. Sam had lived with Dean all his life. Even though Dean thought he could hide it, Sam knew when Dean was afraid. And now...everything was telling him Dean was getting freaked out.
With his hand still locked on his arm, Dean slowly led them closer to the mouth of the tunnel. Sam frowned, eyes squinting.
The creature was a doe. She was lying on her side. Her breath came in shallow, strangled pants. Her throat was crusted in fresh blood. Her eyes swung wildly in her head, tracking them as they drew closer.
"Dean...is it?" Sam began, but the question died in his throat. He noticed the fang marks. Her eyes. Her stillness.
He gasped audibly.
Paralyzed. The doe was paralyzed.
Shuttering realization shot through Sam like lightning. He took a stumbling step back away from the poor creature.
Was this display a threatening gesture?
Or was it a gift?
Either way, Sam knew for a fact what had done it.
He opened his mouth to speak, but Dean's voice cut through the silence like a serrated knife.
"There's another Naga."
