Hi, again! I was browsing my laptop on a boring day when I found this story buried under the dust bunnies… The story is about nagas mating season! I got the idea from esama's Serpentine Illumination! (Great story, by the way, hope she update it more frequently) And, please, could anyone suggest a title? I rocked my brain trying to find one but nothing came to mind!

Summary: Atemu has been following the trail for days… The scent so alluring that compelled him to find it and fast! Mating season was almost over…
Pairing: AtemuxYami
Warnings: This story is rated M for a reason! We have mating, more mating and then, some more mating! Oh, and some MPREG!

Disclaimer: Yugioh! Belongs to Kazuki Takahashi and every other who made this anime/manga possible!

- SERPENTINE (?) -
- Chapter I -

The world was slowly fading to grey, all color slipping away as the last light from the setting suns was sucked down beyond the sands. All life was slowing and would soon still as the daylight creatures settled for the night. However the stillness was nothing but an illusion, the quiet unbroken by those whom the night woke.

But not all of the creatures who slipped through the black-cast world were nocturnal. Some were up to no good.

The grass parted silently beneath the rich brown tail. In the sunlight the scales reflected rainbows of warm colors and, if one looked closely enough a V pattern of gold scales could be made out along the tail, a rich combination of earthy colors that was common in his line. The creature paused, rising up high as his eyes studied the banks of the Nile. The tip of the serpentine tail flicked, crushing some of the grass against the ground. Instantly, the tail stopped and the creature hissed out a quiet curse as he curled the end of his tail as a reminder to keep quiet. Crimson eyes narrowed and a dark smile appeared upon the handsome face as the creature saw the remnants of the trail he'd been following since the setting suns had announced the start of mating season.

Lowering himself he followed the trail, sharp eyes watchful for any predator foolish enough to think him less then what he was and take him for easy prey. He crested the small rise and paused in the moonlight shadow of a palm tree so that he could again rise up to his full height and peer down at the darkened edge of a stream. Cocking his head he sniffed and his lips pulled back over white teeth and sharp fangs as his suspicions were confirmed.

Licking his lips he lowed himself until his tanned stomach nearly touched the ground and slithered forward, following the delicious scent that made his mouth water and the area just beneath his scaled waist ache. He moved with painstaking slowness, trying to stay in the thick brushes to hide his extensive tail, even though branches caught in his tri-colored hair and tangled in his crown.(A/N: Yes, this creature was royalty) He paused often, testing the air for both his prey and for predators, following the tantalizing scent to the water's edge. Pausing at the border between dark and moonlight he failed to look where he was placing his hands and the weight of his human half caused a branch to snap.

The sound shattered the silence and he froze but it was too late.

Instantly he heard the sound of something splashing into the water and he dove out, hoping to catch his prey. But all he saw was the tip of a black tail disappearing up the banks of the Nile. Growling to himself he gave chase.

His prey was quick but he was larger and his extra length gave his side-wind greater power, allowing him to catch up to the one he followed.

Sensing impending defeat his prey hit the high ground and whirled upon him, a combination of a snarling hiss and threatening rattle making him rear up and sway as threateningly as the one above him did. Though it was dark and his sight was more influenced by movement he was able to study his prey, even as the other calmed slightly to study him.

His prey's human half was quite handsome, not as broad across the shoulders as his but the torso was as long and the stomach as strongly muscled. He was of the line of naga whose snake half dipped very low upon his human half, placing his sheath at the bottom of the V of scales. He knew from the few quick glimpses he'd managed to catch of the other that his human skin was pale and it matched beautifully with the black scales of his tail. He had been able make out a dark-purple diamond pattern in the black scales down the back of the other's tail and a delicate row of the reddish-black scales framing his stomach. And off to the side he could see the furiously shaking rattle that warned him off.

That tantalizing scent reached him again as the wind shifted and he rolled back his shoulder, rising up as high as he could to show off his height and the thickness of his tail. He swayed seductively, trying to both calm and arouse the one before him. The other glanced down his body and he took a moment to glance down as well, the muscles of his stomach tightening as he studied the other's sheath and the very slight bit of pink flesh that peeked out from the top. His lips peeled back in a grin as he swayed forward, his eyes narrowed, searching for any sign of flight from the other. He was more than happy with the end result of his adventure. He'd been following this one for days, attracted by the cloying scent and unusual coloring.

"I am Atemu" he said, his deep voice startling the other. He placed a hand upon his chest, his sharp nails running down his stomach to trace over the muscles there. He bit back his laugh as the other's eyes followed his hand's movements… all the way down before suddenly tearing themselves away from that part of him. There was no answer from the other but he could tell from the way the small back shivered, he dared go no closer. So he began to circle his prey, being more then obvious about his interest in the black tailed beauty.

The rattle slowed and then finally stopped as the other watched him with suspicious eyes. "You've been following me" he accused. Atemu laughed and suddenly swayed towards the other, his tail curling about the smaller naga.

"Of course" he breathed, pulling his human half away from the suddenly bared fangs, but not before he had caught a glimpse of the other's back… and how far down the other's spine scales dipped to V in the back. He tore his eyes away from that area and shook himself slightly to regain his focus. He'd always had a weakness for that particular variation in their kind. "What is your name?" he asked, pulling back to give the other the illusion of space but still keeping his golden tail ringing the other.

Coral lips pinched as though the other was going to refuse his request but when his gaze slid down again to the other's obvious arousal a shudder ran through the pale form and he got the name of his prey.

"Yami"

Atemu smiled. "Yami," he glanced down at the black tail and nudged the smaller rattle with the end of his own tail "You do not look like any of the nagas I've seen before"

Yami shrugged, a hesitant smile come to his face. "I like the weather here and the water is clear enough to swim"

The tanned naga nodded thoughtfully. "It is a good place to hide, too. There is no scent"

The wind shifted, as the fickle night winds were meant to do, and Atemu golden hire brushed over Yami's shoulder. Atemu watched as the smaller naga's eyes slid closed and another, stronger, shudder ran through his body. It was even strong enough to make his rattle give out a faint shake.

Sensing his moment Atemu swayed closer, pressing himself against the smaller naga's body. Yami's tri-colored hair much like his own was as soft as silk against his cheek as he molded to his prey's back, his hand slipped around the trim waist so that his palm rested against the gentle swell of the black naga's sheath. The body against him arched as he massaged the hot flesh, his tongue darting out to lick his lips as more of the burgundy flesh slipped free of the scaled sheath. With it came an even stronger release of the pheromone, making Atemu growl softly, as his own body was affected.

Yami turned his head towards the sound of the growl and gasped as the tanned naga's lips crashed down upon his, forcing his head back as the other rose up over him and then pressed him back. He whimpered as poisonous fangs pressed against his lips, forcing him to open his mouth or risk being cut. The moment he did so, however, a tongue forced its way into him, stroking his own in firm, controlled sweeps. The shudders had become constant now and Yami felt his eyes slip closed as he gave into his body's urges, knowing he could not fight nature nor his own desires with the commanding creature so near to him, feeding off of his pheromones as being in heat made his body sensitive to even the slightest of touches.

Another growl rumbled through Atemu's chest as he felt the pale naga's surrender. Lips still locked firmly to the other's he finished his circle, coming chest to chest with his prey. He felt the hot, bared flesh against him and arched forward, swallowing the cry as the soft scales of his underbelly undulated against the other's swollen organ. His nostrils flared at the scent Yami was releasing and he pulled back, baring his fangs to the night sky as he felt his own organ slip free of its sheath.

Something touched the hot flesh and he arched and growled, staring down as his new lover lowered himself, bringing the hot flesh to his mouth. Atemu grunted softly as he buried his hands in Yami's hair and thrust forward, burying himself in the cool mouth. It felt heavenly against his too hot flesh and he thrust eagerly, enjoying the sensations that ran through him from the tip of his cock to the tip of his tail. He growled when Yami pulled back but the sight of the lust hazed eyes was enough to quiet him.

Moving forward he dipped down even as his partner rose up. Wrapping his arms around the smaller naga he found himself face to face with the handsome creature and spared a moment to meet him in another fierce kiss. When he gently pushed his lover back, Yami let him, sending them both in a slow decent to the ground. The cooling sand was soft and the cold helped calm Atemu enough to allow him to slow down and simply enjoy the feel of the warm body coiling with him. Yami must have spent the afternoon hours sunning to retain such warmth and Atemu reveled in it. Their tails coiled, pressing him firmly against his lover and he pulled back a moment to align himself. The head of his cock pushed against the slit beneath Yami's sheath and he lowered himself against the black naga before a ripple of strong muscles pushed him up and into the other's body.

Yami arched and hissed, his eyes closing in bliss as the tanned naga slid home into his body. The muscles of his lover's body moved sinuously, causing the golden tail, wrapped about his, to shift and ripple as the thick cock rocked and slid in and out of him. His eyes opened and he stared up into the larger naga's face, and he felt a rush of lust for the strong creature above him.

Gripping the thickly muscled arms he arched, pushing more of himself against the golden tail and the glorious flesh that parted him. Another rush of lust ran through him and he shuddered, arching so much that his head rolled back and he felt the sharp points of his hair digging into the soft dirt beneath him. The smell of fresh earth could not disguise the heady musky scent of the one above him and he hissed fondly at his lover. Crimson eyes opened above him and he moaned as he felt Atemu's penis split, sharp spines that did not hurt gripped him, trapping him to the dominate naga as he felt the first gush of seed flow into his body. He writhed against the other, tugging at the cock trapped within his body and relishing in the feeling of being tied to the larger male. Sharp nails ran over his own flesh and he cried out hoarsely, causing his own seed to splash against his heaving stomach. He continued to twist and twine against his dark lover, milking all of the larger naga's seed from him until Atemu grunted softly and lowered himself down upon him.

Chest to chest the two naga's drifted off into sated sleep, still tied together as Atemu's seed went to work.

Well? What do you think?

I'm sorry if there are some punctuation errors or even grammar ones… English is not my first language but I did try!

I have two more chapters of this one but I don't know if I should continue beyond that. This story was when I was still in high school LOL

Figures why I didn't do well on those years… XD
