No way, Dean thought. His breath was caught in his throat. There's no way.

Sam stared at the test, his mouth twisted in resolve. His shoulders deflated. "I told you."

"Sam...you can't," Dean breathed, his fingers twitching, reaching out for the test. Without looking over his shoulder, Sam handed it over.

"I told you." Sam repeated. "I'm pregnant."

Dean's head swam as he stared at the two pink lines.

Pregnant.

Dean's vision blurred. He moved away from the recliner and slithered across the room. Sam's eyes darted across his back. His brother's shoulders were a tense line. There was no way to know what Dean was thinking. Sam sat up straighter. Seconds bled into minutes.

"Dean, you okay?"

Dean whipped around. You would have thought he'd won the lottery. He was grinning ear-to-ear, his eyes wet with unshed tears.

"Holy shit, man. This is...this is amazing."

Sam's mouth dropped open. "W-What?"

Dean tossed the test over his shoulder. It landed with a clang against the wall, falling into the dark. Dean slithered back over to Sam and practically snatched him up. Dean peppered Sam's cheeks with kisses, smoothing his hands over his arms and chest, anywhere he could touch. Sam squirmed.

"Oh, Sammy," Dean purred, licking Sam's mating bite. Sam's tensed, eyes screwing shut as his body ached for Dean's hold. Flashes of pink and red splayed across his vision until Dean's lips moved onto his throat.

Sam's expression soured. "Amazing? How the fuck can you say that?" He shoved at Dean's shoulders until his brother released him.

"We're going to have a family," Dean said, hands poised on either armrest, caging Sam in.

Sam choked in disbelief. "A family? You really want that? Some fucked up snake man hybrids?"

"Just think. A little one. A little one to love." Dean whispered, waves of unabashed love slamming into Sam. Sam's mating bite throbbed.

Sam wrapped his hands around Dean's broad biceps and squeezed. "Have you lost your fucking mind?!"

"Everything is going to be alright." Dean hushed. "You're going to be fine, Sam."

"How can you say that?" Sam choked. "I'm knocked up, Dean. With your freakish babies."

"Babies?" Dean reached out and brushed a lock of Sam's hair away from his forehead. "You think there's more than one?"

"That's not the point!" Sam shouted. "How am I going to give birth to them? I don't have a vagina! Where are they supposed to come out of? And I...I don't even know if I can survive this!"

"You will survive this. You know how I know that? Because you're strong, Sammy." Dean said and reached for Sam's sweatshirt, trying to pull it up. "And your body is prefect. It will know what to do."

"Dean," Sam whispered, hands darting down to grasp Dean's knuckles. "You can't be serious. You really...want them?"

"Yes." Dean whispered. "Of course, man."

Sam licked his lips. "But what if they're like you?"

Dean's expression faltered. "What do you mean?"

Sam glanced at the slaves in their cage in the corner. After a handful of seconds, Dean's voice broke the silence. "A monster? That what you mean?"

A wounded look flashed across Dean's face. It was so quick Sam thought he'd imagined it.

"Dean."

"Let me see." Dean said, nodding to his stomach. Dean's eyebrows were knitted in hurt but he still had that smile stubbornly plastered onto his face. "Please?"

Sam's grip loosened, his strength draining. He sighed. Dean's impossibly wide smile grew even wider. What was the point? Dean was so happy. He wasn't going to give up until he got what he wanted. Dean lifted his sweatshirt.

Dean gasped.

Sam squeezed his eyes shut.

"Sam, you never showed me."

"You didn't believe me."

Dean clutched at the sensual, subtle swell of his brother's abdomen. Sam had hidden his progress well, with his oversized sweatshirts and ill-fitting jackets. He stroked his soft skin, one clawed thumb carefully tracing a line down the slope. Nestled inside Sam, Dean understood with his whole Naga self, was his offspring. Sam was carrying his babies. Nothing was more perfect. More sweeter.

Dean couldn't help himself. He began pressing heated kisses down Sam's abdomen, tasting the salt on his skin. "Baby," he moaned. "Sammy."

Sam breath caught in his throat, his eyes fluttering open. Dean's hands were gentle on his sides. Sam squirmed at the affection lavished on him. Sam couldn't remember a time Dean was so gleeful. Maybe when he was human. But not after. Not after what happened to him.

But now...now Dean was treating Sam's body like it was a foreign god and he was a blasphemous sinner.

"Dean," Sam repeated, his voice hesitant, on the knife's edge of giving into Dean's plush mouth, the festering agony of his skin which shivered underneath Dean's affection. Dean was practically beaming, the happiness coming in waves, like rays of sunshine breaking through a cloudy sky.

Something trickled from Sam's entrance.

Wet.

Slick.

Dean suddenly picked him up. Sam squealed in surprise. Dean rose on his massive Naga bottom and slithered over to the bed, hastily-but gently-laying Sam down on the bed. Sam's sweatshirt rode up to his chest. Sam peered up at his brother. Dean's expression was void of human emotion. It was as if a switch had been flipped. Dean hissed and slowly crawled up Sam's body.

"D-Dean." Sam said, suddenly afraid.

But Dean blinked rapidly and that animalistic coldness was gone, replaced by unabashed heat. Without warning, Dean attacked his nipples.

"Dean, ahhh," Sam groaned, back arching. Dean found his left nipple and sucked, pulling the tight, pink bud between his mouth, punishingly rough. Sam pawed half-heartedly at Dean's shoulders and chest. He didn't know if he wanted to pull away or push forward. God, Dean's mouth felt good. It was like a line had formed straight from his nipple to his dick.

Sam's cock filled with blood embarrassingly fast. Dean switched nipples, cupping his lips around the right bud and sucking sinfully. Sam moaned. "Fuck, Dean. S-stop."

Dean sucked harder. Sam grasped the back of his head and shoulder, squeezing. After a few minutes, Dean pulled away. Sam's chest was a wet mess.

Before Sam could say anything, Dean pressed his lips against his. They kissed for what felt like forever, wet appendages shoving past unyielding lips. Dean began to undress Sam. Sam did not fight back. Although he did not want to face the fact in the heat of the moment he knew it to be true: he wanted this. He wanted it more than anything. His whole body thrummed with electricity, with unabashed want. To be wanted by someone so much was overwhelming.

Before he knew it, he was naked and shivering before Dean's eyes. Dean's lips traced a path down his body, landing on places that sent Sam's chest into a tight, hot spasm: throat, chest, stomach, calves. Dean let his fangs scrape sensually along the inside of Sam's thighs. Sam's cock, erect and throbbing, leaked pre-cum with each throb of his heart. His pucker leaked, eager to be filled.

Dean lifted his hips and kissed his entrance.

"Dean," Sam gasped, fists balled up in the bedsheets, bone white.

Dean peered up at him through his eyelashes, a predatory smile curling on his face.

"Sam," Dean replied, teasingly.

"What...what are you doing?"

"What does it look like I'm doing?" Dean cooed. "I'm gonna eat your ass."

Sam's stomach tightened, his heart throbbing. Yes, he thought. Please.

Dean's long, wet tongue darted out, lapping at his pucker until Sam was begging. Begging for him to stop? Begging for him to never stop? He didn't know. Sam was shrunken down to a series of mindless utterances. Desperate pleases.

It was only when Dean's tongue was so far up his ass that he was nearly screaming did Dean retract his mouth.

"No," Sam moaned, chasing the feeling as Dean pushed up, hovering over him. He'd been so close. He needed Dean's mouth, his tongue. Sam clawed at his chest, "Please, don't stop."

Dean smirked, "I got something even better."

Dean's massive, monstrous cock snapped out of his tight, masculine slit. Twitching and leaking. Seeking him. Sam sighed when he saw it. A soft, quiet sound. Involuntary. His dong writhed between them.

Hands against hands, chest against chest, somehow in the tangle of sudden, unabashed need, Dean ended up on the bed, Sam hovering over him. Dean's ginormous snake half stretch across the room, shivering sporadically. Twisting and curling and thumping against the concrete.

Sam, practically delirious with a primal need to fuck, straddled Dean's stomach. His eyes not leaving Dean's, he reached back, grappling for his cock. His fingers locked with the thick, meaty girth.

"Fuck, baby," Dean moaned. "You wanna ride?"

"Mmmm-mmmmhhh," Sam agreed and lunged for Dean's mouth. They kissed until both men's lips were numb, until Dean's cock was as erect as a telephone pole.

Sam grabbed his ass cheeks, spreading himself wide, and peering behind himself to meet his mark. He pushed himself down on Dean's cock. It was slow at first, working each inch inside him, careful not to let his intense craving override his rational mind. The sensations sparking behind his eyelids were overwhelming.

Dean's hissed in choked, smoldering pleasure. Sam's tight, wet channel squeezed around his thick girth. Dean bared his teeth, his eyes falling half-shut. His muscles tensed involuntarily. Dean balled his hands into fists on either side of him. His claws sliced through the cotton sheet like butter. It took everything in him not to seize Sam's hips and push him up and down on his cock until Sam was screaming and writhing in pleasure.

Sam shimmied his hips, making himself comfortable. His glistening, pink mouth was popped open, his eyes half-lidden. His sweaty overgrown mop of hair hung over his forehead. His breath came in harsh pants. He seemed drunk. Love drunk. Dick drunk.

Dean could barely stand it. His control was fraying. His hips ached to push upward, to shove himself deeper. To fuck Sam until he remembered how much he loved him. Instead, Dean reached out one hand and traced it over Sam's hairy thigh and up until he grasped the soft, subtle swell of his abdomen. He rubbed underneath Sam's belly button.

"Sammy," Dean moaned. "Move."

Sam's eyes darted down to meet his. Sam reached down and grasped Dean's hand. "I just wanna feel you inside me."

Dean shivered. "You like that?"

Sam moistened his bottom lip. "Yeah," he admitted. "You feel good."

"You feel good, too," Dean purred. "Love how wet you are for me."

Sam's face flushed. He rubbed Dean's fingers where the digits stroked his belly.

Dean continued, cooing: "Now we know why, huh? Your body changed. Changed so I can put babies in ya."

Dean's serpentine eyes flashed and he smiled, baring his fangs. Involuntary quakes raced down Sam's back at the praise. A part of him felt ashamed at how much he loved Dean's naughty utterances. He shouldn't feel proud he was capable of carrying a man-eating predator's offspring. But a little part of him was.

Before he could think too much, Sam pulled up on Dean's cock and then slammed back down. Dean shouted, spittle flying out his mouth. Sam threw his head back. Dean's hands darted out, grasping his hips. With each push down, Dean's member hit that delicious spot inside of him. That spot that made him see white dots across his vision. Sam rode Dean for several minutes. Dean stared, captivated, at Sam on top of him: the curve of his spine, the sweat dripping down his jaw, his unabashed beauty.

In the middle of their love making, Sam barely noticed when Dean pushed him off his cock and twisted around, covering Sam's sweaty back and maneuvering him into doggy style.

Sam simply moaned as he found himself on his hands and knees, Dean's cock breaking through his entrance, as he fucked him from behind. Dean's fingers dug into his hips so hard Sam knew he'd have bruises. Dean's cock popped in and out, in and out, at a breathtaking speed.

"Fuck, ahhhh, yes, yes, yes," Sam whimpered, tossing his head back. Dean ravished his throat with kisses and love bites. Sam's own cock jerked back and forth, helpless and untouched. He didn't need it touched. Not now. Not with this body. Dean released his hips and lurched over him, panting dirty, depraved strings of sentences into Sam's ear.

"You like that, Sammy? You're so tight." Dean purred. "So tight and wet. You're so handsome with that little belly."

"Yes, yes, yes," Sam moaned, pushing back to meet Dean's thrusts.

"Gonna take good care of you. Gonna take care of you and the babies. I'm gonna be the best Daddy. Just you see, Sammy."

Sam groaned. Dean pushed in and out, in and out, until the burning heat in Sam exploded into stars. "You hear me?"

"Yes," Sam moaned, shivering as Dean latched onto the bite and sucked.

"Good," Dean whispered, licking into the shell of Sam's ear with sensual swipes. His thrusts sped up until he was slamming into that delicious spot inside Sam over and over again. Sam's balls tightened. His cockhead twitched.

When Sam climaxed, it was Dean's name on his lips. Sperm shot across the bed in thick strings. Seconds later, Sam felt Dean's hot load shoot inside him, impossibly hot and deep. Dean held himself still for a moment, relishing the creamy cum that drippled out between his dick's bottom and Sam's tight entrance.

All at once, as if strings had been cut, they collapsed in a sweaty heap on the bed. Dean's dick zipped back inside his body. Sam moaned as he was maneuvered into a spooned position, his back to Dean's front.

"Sleep, baby," Dean murmured into his ear, caressing his belly.

Sam's eyes fluttered shut from exhaustion. Sleep took him swiftly.
