Atem froze when he heard Adina barge into his room without warning, and he sighed.

'Manners' was not a word in her vocabulary, just like Kaiba.

Finally managing to slip the last golden armband around his wrist, Atem called to her over his shoulder, "Adina. What did I say about waiting outside? I'm getting dressed."

Oh, is he? My imagination is that good, Kaiba thought gleefully, advancing towards the mysterious black curtain in the far back of the room, and his stomach twisted nervously at the thought of pulling it back to reveal…no one inside.
No.
He couldn't have doubt.
This was his lucid dream.
It was going his way, or no way.

"Adina, I'm warning you," Atem sighed, and he emerged from behind the kelp curtain, his voice catching painfully in his throat when he saw Seth eyeing him hungrily with a glint in his eye.
Oh, gods.
What had happened?

"Even you need to wait outside," Atem said firmly, hoping his voice didn't shake and give away how he really felt. "Please, Seth. I'm really not in the mood to fight with you."

Kaiba felt as if he'd been hit in the face with a rock, and he stared at the mer-king, taking in his wonderful silhouette and his spiky tri-colored hair fixed to perfection, but he looked…tired.

He had dark circles under his usually bright eyes, and he was missing the golden neckbands he usually wore.

Okay, weird. His own imagination hated him and needed some fixing.
Whatever. Fuck it.

He darted forward in the water and tackled Atem into a crushing embrace, careening through the kelp curtain and crashing into the various plates and jars of gems inside, pinning him to the wall at the far back while the king remained frozen in his arms with shock.

Multicolored gems rained down from the shelves around them, bursting from their glass containers when they hit the ground. Before Atem could blink, Seth attacked his neck with a flurry of passionate kisses, sending his stomach churning in a wonderful frenzy.

Oh Gods…no…this was wrong…

But it felt so good….

This was wrong!

Atem mustered up all of his strength to give Seth a shove, thrashing his tail out for good measure and seeing Seth cough but refused to let up.

"Thanks. I love you too, babe," Kaiba said venomously, baring his fangs unconsciously.

"This is…not…constructive!" Atem struggled to catch his breath while trying to put his feelings into words as he felt Seth's aura darken dangerously fast, too fast, almost matching the speed of Kaiba's mood changes. "It's…not a constructive way…to mourn…your brother!"

Kaiba blinked and stared incredulously at Atem.

What the…fuck was this guy spewing?!

"Stop it," Atem begged tearfully, pressing his hands flat against Seth's toned chest to keep him at bay, feeling his palms burn with longing in response. "We should wait at least three moons before mating. Just know that…you can never replace him."

Kaiba stared haughtily at Atem for a few seconds before he flew into a rage.

"Are you fucking Seth?" Kaiba spat, feeling acid frothing at the corners of his mouth, and he backed out of the strange closet to gaze around the room again, wondering when this nightmare would end.
First Kisara, and that was fine, but now…Atem?!
Maybe he should've killed Seth on sight, goddamn.

"What are you thinking about?" Atem raged, emerging from the ruined treasury and glaring at the long-haired merman. "Why are you referring to yourself by…" name, Atem finished, terror-stricken as he gazed at Seth, who was seething before him—absolutely incensed, so much that his handsome face was twisted into an ugly sneer…reminiscent of….

"Kai…ba?" Atem barely managed to register this thought before he found himself pinned to the farthest wall of his room while Kaiba's face floated eerily above him, nose-to-nose for a mere heartbeat before his lips came crashing down to meet his own in a desperate rage.

Their fangs grazed in the midst of their passion, and Kaiba tasted blood in his mouth.

Atem drew in a sharp breath, his head spinning so fast he felt like he was floating…floating upwards into the musky scent that was uniquely Kaiba's.

He threw his arms around Kaiba and pulled him in closer, hanging on tightly and wishing he could never let go. This was a dream…a horrible, wonderful dream.
Yes, he had fallen asleep, and when he woke up, he'd be alone again, as usual.
But for now, he could enjoy this…as if it was real.

"Shut up," Kaiba gasped, pulling away breathlessly and gazing into Atem's large, violet eyes which were half-lidded with lust.
He'd dreamt about this so many times, he wasn't sure if it was real anymore.
It didn't matter.
Now was what mattered, even if it wasn't real.

"You shut up," Atem grinned playfully, sticking his tongue out to lick Kaiba's lower lip, and Kaiba shivered with happiness.

He pressed himself insistently up against Atem's body, relishing in his warmth while his mind hummed with pleasure and shut off.
Yes…holy fuck, yes.
This was what he wanted.
To feel Atem's…tight, muscular body against his, forever.

Breaking away for air, Atem pushed Kaiba forward with all his might, hearing his partner hiss at him in annoyance, and he hastily pointed at the bed, his finger shaking with anticipation.

Kaiba stared briefly at the strange, spongy bed, and his stomach churned when he saw his own arousal sticking straight out from his body.
That was a weird sight.
Don't look at it.

Atem grinned and pushed Kaiba down onto the bed, daring himself to enjoy the way his light brown hair splayed across his pillows. Beautiful.

Kaiba's chest tightened with anxiety when he realized…he didn't know how to have sex with fins attached to his lower body. The thought quickly evacuated his mind when Atem's hand came down sensually along his heated member, and he felt himself leak with excitement.

The sensations…were the same.
It just looked different.
Yeah, he could deal with that.
Probably.
Maybe.

"Stop it," Atem breathed, pressing his palms against both sides of Kaiba's sloping cheekbones, his eyes roaming over every inch of Kaiba's face, trying to stamp every single one of his lewd expressions to memory.

"I'm not…doing anything," Kaiba struggled to speak, but his tongue kept getting cut on the tips of his fangs which were once again protruding annoyingly past his lips.

"Think…about me, and how much…you…want it," Atem said, his voice lowering sensually as he inched his way down Kaiba's toned abdomen and teasingly grazed his teeth along a sharp hipbone. "Watch…and wait…"

Holding his breath anxiously, Kaiba tilted his head forward to see Atem grab his writhing dick and bring his head down heavily onto it to begin sucking and rolling it wonderfully on his tongue, pausing to pocket the sensitive tip in his cheek before grazing it against delicious ridges from the roof of his mouth, sending a heated thread of pleasure shivering down his body. Atem continued excitedly, lifting his head up to bob down on it and letting his breath out in a steady stream of bubbles.

Dizzy with amazement and arousal, Kaiba watched the bubbles float up to the ceiling, his ears rushing with a loud sound. H-Holy…f-fuck…

He could cum like this.

Too soon. No. Wait.
Fuck. Too soon.
Atem…st—

Atem paid no mind, giving Kaiba's tip a lewd swirl and feeling his dick tense excitedly in his mouth before a heavy, sweetness coated his tongue in a pleasurable rush, and he swallowed it excitedly. He'd always wondered what Kaiba would taste like, and it was…heavenly….

Gasping for breath, Kaiba tried to come back down to his senses, but Atem wouldn't let up. After his mouth left his dick, then came a hand. A warm, beautiful, tanned hand adorned with various golden rings, stroking him slowly up and down, blanketing him in a haze of ecstasy.

Barely able to keep his eyes open, Kaiba watched as Atem gave him a few more practiced jerks, sending searing waves of fire and lust raging through his body. His stomach clenched with an orgasm, and Kaiba curled oddly, doubling over as he shuddered ecstatically, waves and waves of pleasure assaulting him violently.

Just…from his hand and mouth. It was too much.

I can't breathe! I can't…breathe! Kaiba gasped, his chest heaving and his stomach clenching at different times, and he barely registered Atem hovering above him, smiling handsomely as he slipped his own dick forward to give them both a sensual rub.

His vision faded strangely, and Kaiba finally managed to take in more of what was being done to him.

His dick was…sliding strangely, up and down as if it had a mind of its own. It stayed tightly interlocked with Atem's arousal, and Kaiba couldn't stop staring at it. It was…protruding from underneath his navel, stiffening and dancing every time Atem bent down over him to touch him…with his own, odd, springy tentacle.
It felt as strange as it looked.
Everything was a hot, blurry haze, with Atem always keeping him on the brink of a mind-bending orgasm, but never too close, torturing him on a heated peak he could never reach.

His face was hot, his ears were burning up, his chest was on fire every time Atem raked his hands down his front with his beautiful lips parted, sometimes coming down to meet his in a fiery kiss, other times, it was a slow, tender, loving worship, with fangs and tongue. Combined with the repeated, slow grinding from below, Kaiba threw his head back and felt himself soar on the highest cloud, his heart rushing with joy, beating so fast, he couldn't feel it anymore.

This was death.

The heat subsided from his lower body, and Atem surged forward to kiss him languidly, slipping his tongue sensually in through the fronts of teeth and giving the roof of his mouth a suggestive lick, setting Kaiba's insides on fire.

He slowly raised his arms and wrapped them around Atem's tanned shoulders, pulling him down deeper into the kiss, parting his mouth hungrily, wanting more…more of everything. This new discovery of multiple, satisfying orgasms while in mer-form was the best gift from the gods who had always been cruel to him.

"Did you like that?" Atem asked cheekily, brushing a strand of Kaiba's long hair away from his cheek. "Ready to show me how fast you learn?"

Oh…fuck yes.

Kaiba tensed and dove at Atem with expert speed, rolling the king over onto his back and kissing him furiously, curling the tips of his fins around Atem's, much warmer ones, his heart thudding with longing.

He could feel Atem's dick pressing insistently against the base of his stomach, as if teasing him to continue, so he did, sliding his hand down the king's front and gripping his arousal with one hand, making sure to slowly drag it upwards, knowing it elicited hot streams of fire down his spine as Atem shivered. Sexy.

Letting his breath out in a proud huff, Kaiba bent forward to drag open-mouthed kisses across Atem's collarbones, enjoying the way Atem stroked his hair and splayed it out around them magnificently.

This was pure bliss, pure heaven—

Someone knocked roughly at the door, and they both tensed angrily.

"Go away!" Atem shouted hoarsely, his erection curling painfully at the loss of contact.

What in the gods…?!

The person knocked so loudly, Kaiba felt a headache coming on.
Goddamn, what the fuck?! It had shattered the golden bubble of heavenly sex.

"Stop that! I'll answer it!" Atem raged, aiming to get up, but Kaiba was already at the door, fuming.

Throwing it open, Kaiba didn't care that he was basically showing his dick to whoever knocked. They wanted to be left alone!

And…fuck, it was Mahad.

The warrior gaped at him, his violet eyes slowly sliding lower along his body as his face turned beet red, and he opened his mouth to protest before Atem's tanned arms wrapped around Kaiba's pale torso, pulling him back inside the room, and the door slammed in front of him, nearly catching the tip of his nose.

Shocked speechless, Mahad swam shakily down the end of the hall to report back to Mana and the Medic.

Both women accosted him at the hallway entrance, their eyes wide with silent questions, and Mahad couldn't believe the words coming out of his own mouth even as he said them.

"Seth and Atem are mating…as a way to cope with their grief," he said nervously, and both women turned red while they continued to blink at him.

"So…he's not dying in there?" Mana squeaked, covering her face with her hands while she blushed. "I keep hearing, 'I can't breathe' and 'oh this is death'! That's the sound of them…Mating?! I'm so embarrassed!"

"Now I can't breathe," the Medic muttered, swimming away back to the infirmary, relieved.

Waking up to discover an empty pod was bad, but what made it worse was the odd gasping noises coming from the king's chambers.
Horrifying. Men were scary.

Kaiba swam back to the bed and threw his arms around Atem, pushing him down into the soft sheets as he buried his nose into the crook of his ear and inhaled deeply, filling his lungs with a wonderful, fresh scent.
Fuck. He'd never get tired of this.

"Good, because I can go for days," Atem grinned boyishly, pushing Kaiba's shoulders down insistently. "Go on. It's my turn."

"It'll never stop being your turn," Kaiba smiled back prettily, baring his fangs for a moment before he put them away and decided to drag his tongue down from the center Atem's chest to his navel, and he felt the king squirm happily underneath him.

His mind flooded with warmth when he pressed his nose against Atem's arousal and took him into his mouth, feeling it thrash pleasurably along the inside of his cheek, and he held his breath, slowly sliding his hand up and down Atem's hip, angling his eyes up to see the king nodding encouragingly at him.

He pulled away slowly to watch the tentacle do its strange dance, and he heard Atem hiss in annoyance.

Gathering water between his teeth, Kaiba playfully shot a careful stream directly at it, feeling Atem's fins curl with excitement underneath him, and the king gasped.

"W-What is that feeling? How are you doing that?" Atem demanded as his stomach curled with raw pleasure. "A-Again."

Smirking, Kaiba didn't obey, and he surged forward to take Atem's dick in his mouth, sucking, rolling, and sucking some more, feeling himself itch all over with lust at the memory of being fucked by this thick, curling dick.

But he didn't want…another egg fiasco.

"It doesn't happen every time," Atem said reassuringly, stroking Kaiba's hair tenderly. "Also, you weren't supposed to carry her to full term. Eggs get extracted, at…half a decade, sometimes even sooner."

Kaiba's blood ran cold at this new information and he couldn't stop his rage from rearing its ugly head.

"You mean…I fucked myself over for no reason?!" Kaiba raged, and Atem's hands cradled his head gently, his violet eyes sparkling with mirth and admiration.

"Why would I burden you a second time with another child with tantrums like Adina?" Atem cried, biting back a laugh. "I will gladly do the bearing now that I know you're not going to run off with some white-haired shore-maiden!"

"Keep saying that shit and my boner will die," Kaiba said coldly, closing his eyes and pressing his forehead tiredly down on Atem's shoulder. "How does it work? We're both…men."

"Keep saying shit like that, and my boner will die," Atem replied just as seriously, not wanting to discuss egg-bearing in depth while trying to rekindle years of latent passion. "Let's not think about it too much. Do you need sleep? Close your eyes for a bit, and we can go again. You just healed. I might be asking too much of you."

Kaiba let out a soft groan and fell onto the sheets beside Atem, feeling a warm arm draping over his chest, slowly drawing small circles across his skin.

His head spun, and the air was getting thin again.
Fuck.
He didn't even get to…fuck Atem, or get fucked…

"Just…sleep," Atem insisted, pulling the sheets closer over Kaiba's fins. "I'm also tired because I haven't eaten. I've always wanted to have a good rest with you."

Me…too, dammit, Kaiba thought, already drifting off. His body felt wonderfully light, like he was sleeping on a cloud.

He hoped and prayed with all his might that Atem would still be beside him when he woke up, because he couldn't stay awake any longer.

"Adina?" Mana swam over to the princess and handed the little girl three jars of fish eggs and two spoons. "Take these to your Papa inside his room."

Adina yawned and sank back into her chair at the dining table, pouting at Mana. "No. You do it."

An awkward silence followed as everyone at the table exchanged looks.

Mahad said nothing and kept his head down, intent on eating faster so he could make his escape. It seemed Rishid, Shadi, and Isis had the same plan, because everyone was shoveling food down, eager to be away from the table.

"I…don't want to go in there," Mana said lightly, her cheeks reddening. "So I'm asking you nicely, one last time. Bring the food in for Uncle Seth and Atem—"

"OKAY I'LL DO IT!" Adina cried, her eyes brightening as she zoomed out of her chair and snatched the food from Mana's hands. "Papa and Da—Uncle Seth will be hungry! I'm going now!"

She darted out of the dining hall and Mana sighed, looking around the table for help, but everyone was avoiding eye contact with her.

It seemed word had gotten out that Atem had 'moved on' from Seto after he'd gone missing, and decided to take Seth as a mate. It was confusing the princess.

Mana sat down in front of her own food and palmed her face, feeling a headache coming on.

Adina rushed down the hallway towards her Papa's door and knocked softly, calling out to him in her mind. Papa?! Daddy? I'm bringing food!

Atem lifted one eyelid and found his face buried in a pile of light-brown hair. Brushing it away irritably, he sat up slowly, his stomach churning with dread when he wondered if he had made a mistake.

Seth was sleeping soundly in space beside him. Not Kaiba.

Oh fucking gods…he had made a mistake.

In his grief, he had lied to himself and told himself he'd mated with Kaiba!
But reality was harsh.
This was Seth.
Unmistakably so.

Kaiba frowned in his sleep, wondering why Atem was ranting about Seth inside his head…when his eyes shot open, and he remembered with a jolt that he'd grown a set of fins and dream-fucked Atem. Or not. Maybe not?

Turning his head stiffly to the side, he saw the mer-king holding his head in his hands with sagging shoulders. Golden bands were still fixed prettily on his arms, but he was missing a few, and long waterfalls of claw marks ran down his back, evidence of their lovemaking.

"Hey…" Kaiba breathed, his heart thudding with incredulity and happiness as he reached out to rest a hand on Atem's arm, but to his horror, Atem shrank away and looked at him with large, sorrowful violet eyes.

"I'm sorry," Atem whispered, trying to hold back tears of resentment for himself. "This was a mistake."

"It's me!" Kaiba raged, his temper flaring instantly. "Do you have the memory of a goldfish? We…didn't even fuck properly last night!"

"I know! And I can't believe I fell for your dirty trick!" Atem hissed, unsure why Seth looked so angry. He got what he wanted.

"I'm—" Kaiba swallowed the tightness, which was slowly rising up his chest and wondered if he needed to cut his hair…because, fuck this.
Yes, he would.
Because clearly having sex with Atem didn't make a difference if the mer-king was so hung up about how much he looked like Seth.

Springing out of bed, Kaiba dove towards the spear he saw lodged in the ground, and he yanked it out of the sand, scanning the room for a mirror while Atem gaped at him, horrified.

"And you're going to…kill me now because I won't accept you as a Mate?" Atem said coldly, folding his arms across his chest and wondering if he ought to call for Mahad. "You're delusional."

"I'm…Seto," Kaiba seethed, shaking with contained rage as he pointed the spear at his own neck. "And I'm going to cut my damn hair to prove it to you."

"No! Don't do that!" Atem floated out of the bed anxiously, holding his hands out for the spear, shaking. "Yes, I believe you! I just can't believe that you're back! I've missed you so much…Seto, I was merely shocked when I woke up. Please don't cut your hair. I know it's you."

There was a brief silence as Kaiba stared at Atem, his heart thundering in his chest with confusion.

"What?" Kaiba said coldly, gripping the spear tighter. "What I'm hearing is, you want me to look like Seth?"

Adina pressed her ear tighter against the door, listening to her parents fight, and her heart sank.

"No! No…" Atem breathed, sinking back down into the bed with exhaustion. "I mean, that's fine if you really want to cut it, I suppose. No one will say anything about it to your face…because you're a royal."

"What?!" Kaiba cried, feeling himself slipping into madness. "What are you talking about?! I hate that people will keep confusing me with Seth! I'm going to cut it. It's just hair!"

"It's not just hair!" Atem fumed, changing his mind and darting forward to snatch the spear out of Kaiba's hands. "Having long hair is the mark of a high-ranking royal! If you cut it, you've just told everyone you want to be demoted or are going through a crisis, which you are not."

Kaiba blinked rapidly, trying to process Atem's words.
He still felt a bit groggy, and he wanted a…fucking…kiss, not a fight about his fucking…hair!

"Come," Atem tossed the spear back into the sand with a heavy thump and pulled Kaiba back onto the bed, wrapping his arms around his shoulders tightly, embracing him. "Please, hear this: Joey and Tristan have short hair because they are warriors. Their lifestyle doesn't permit them from growing it out. I don't mean that having short hair as a royal indicates you are in lower class or anything…"

Kaiba rolled his eyes and pressed his cheek tighter against Atem's toned chest, wondering where this talk was going. Atem was really trying his best to convince him not to cut his hair because it would be unclassy.

"Now think about Shada, and Shadi," Atem continued gently. "They have no hair, because they are ambassadors who travel frequently and don't have the time to preen. Now look at Mahad. He has long hair, and he's a strong leader of men—"

"I get it," Kaiba interrupted, wrapping his arms around Atem's waist and pulling him closer. "Long hair equals your status, which tells people you have time to be pampered. Now tell me how your hair stays like that."

"My hair?" Atem smiled playfully. "That's a secret. You'll never find out until there's a little boy in our family."

Kaiba blinked incredulously, wondering how Atem managed to cleverly shift the conversation into all the things he wanted: long hair in his mate, a little boy?!

"You want to have another kid? Forget it," Kaiba growled, landing a bite on Atem's collarbone. "Adina will lose her shit. I'm losing my shit."

"I never said that I wanted another child! Where do you get these ideas?" Atem wondered, his stomach clenching and he let Kaiba plant a kiss on his cheek. "You're always in your head thinking these ridiculous—"

Daddy? Papa? I have food! Adina called, clinking the jars together in her arms. Are you still fighting?

"No, we were not fighting!" Atem cried, untangling himself from Kaiba and diving to the door to pull it open. "How long were you listening at the door? That's rude behavior!"

Kaiba bit the inside of his cheek. Adina was definitely his kid for sure.

"Daddyyyyy!" Adina shoved the jars of food into Atem's arms and dove into Kaiba's lap, curling her arms around his waist and hugging him tightly. "I love you! I even forgot today when I woke up that you were home!"

"Yeah? You're not the only one," Kaiba shot Atem a teasing glare, and the king's face reddened with embarrassment, so he kept his back turned, shutting the door quietly.

"Wanna play with me today?" She asked hopefully, and Kaiba stroked her hair, declining politely.

"I would like to…play with Atem a little more before I play with you, okay?" Kaiba struggled to avoid saying the word 'fuck' and 'sex', hoping she would catch on, but it went over her head.

"WHY?! You already played with Papa a lot! Play with me now!" Adina demanded, giving Atem a glare over her shoulder. "I'm lonely!"

"Want a little brother?" Atem prompted cheekily, and it was Kaiba's turn to glare at the king.

"No, she doesn't," he snapped, but Adina sounded thrilled by the idea.

"YES! Like Noah?" She asked immediately, her eyes shining. "Will he come to play with me?"

"Oh, no, not like Noah," Atem shook his head, grinning handsomely at Kaiba, who kept the sour frown on his face, realizing Atem had met Noah on shore, and Noah was probably really bratty towards him too.

"Then…like who?" Adina asked curiously, looking between her parents and hanging tightly onto Kaiba's hand.

"Someone better than Noah," Atem said warmly, floating forward to scoop her up from Kaiba's arms, and Kaiba opened his mouth to protest, but Adina was already screaming.

"BUH WAIT, I WANNA SPEND TIME WITH DADDY! NO FAIR NO FAIR!"

"Daddy…is going to mate with me for a verrrry long time," Atem flashed his fangs in a tight smile, patting her on the head. "That's how you'll get a little brother, okay?"

"Ew," she made a face and stuck out her tongue. "I don't want him if he's gonna come out of Mating."

"How the hell do you think you came around then?" Kaiba asked incredulously, feeling a laugh climbing up his chest. "A seagull?"

"Yes, all birds lay eggs and that's where we come from," she answered with so much conviction that Kaiba was disturbed.

"Go to your room," Atem nudged her gently out the door, eager to be rid of her. "Be good. Do all your classes and report back."

"W-Will you be done mating by the time I need my Night-Night story?" She asked obnoxiously, and Atem nodded fervently.

"Yes, definitely." Not.

"I just heard you lie!" She cried, and Kaiba watched with rising apprehension as Atem shut the door in her face.

Wow. He had…no words to describe his feelings about that interaction.

"Now, where were we?" Atem sighed and swam steadily over to Kaiba, grabbing the sheets and curling up inside them. He emerged to pat the spot beside him, seeing Kaiba staring blankly down at himself, clearly still in shock about his fins.

Atem bit the tip of his tongue worriedly. Kaiba had also left the pod too early. He was probably suffering some residual trauma from his time on shore. Warriors who served for decades, or even centuries, often adjusted poorly back into mer-society, usually by hankering after their legs and yearning for their Undercover life with humans.
Would Kaiba be the same?
That would be terrifying.
There was a term for it…called…traumatic stress disorder….

"I can hear you," Kaiba said coldly, turning to give Atem a look. "You think I'm fucked up."

"Again, I never said any such thing," Atem protested, growing more and more disgruntled.

He reached out to grab Kaiba by the arm, dragging him into the bed, swooping forward to capture his lips into a tight kiss, his body warming nicely when Kaiba responded with enthusiasm, slipping his tongue thickly into his mouth to taste him.

Smiling, Atem parted his lips and sighed, roaming his hands down the front of Kaiba's toned chest and stomach, his body burning with lust. Just a mere kiss could set him off. It was almost unthinkable.

He lovingly traced Kaiba's nipple, feeling him recoil after he got aroused and glanced down with wide eyes at the tentacle emerging from beneath his navel.
It stiffened and waved excitedly in the water, and Kaiba's chest tightened.

"I can't…deal with…that," Kaiba said hoarsely, and Atem threw his head back to laugh heartily.

"But you can do so much more with it than…your human one," Atem said, eager to show Kaiba a new technique. "Lay down, I'll show you."

Extremely apprehensive, Kaiba did as he was told, setting his head down on the pillow, annoyed that his hair was splaying out everywhere, even tickling his nose.
Ffff...How the hell did people deal with this shit?
He couldn't enjoy sex like this.
Hair was in the way.
The dick was weird.
Everything was weird.
The kid might be outside eavesdropping.
This wasn't what he'd imagined.
Yes, he was aroused, but he wanted what he'd always been accustomed to…not this strange tentacle sex, not that he was complaining, because Atem was the best thing to ever happen in his life….

Atem heard all of these dark thoughts, and he nuzzled his nose tighter against the nape of Kaiba's neck, breathing deeply. He trailed his fingers up Kaiba's hip and slowly reached his hand down his front, resting his knuckles teasingly against his length, feeling Kaiba slowly relaxing under his touch.
Typical Kaiba. Touching him there would appease him.
Touching him anywhere else would cause a tirade of hostile thoughts and impatience.

Rocking himself forward, Atem landed a soft bite against Kaiba's earlobe, eliciting a shiver, so he took this as encouragement and draped his hand over Kaiba's length, refusing to move his hand. Kaiba grit his teeth and bucked his hips forward in frustration, his body oddly hot.

Tease.

Rolling over onto his back, Kaiba reached around Atem's waist, pulling him on top with ease, and gazed longingly up into the king's face, wishing he would wear more of his jewelry when they fucked.

"I hear you," Atem said softly, lifting Kaiba's hand up and pressing a soft kiss into the center of his palm, flicking his tongue out to lick it for good measure.

Kaiba tensed, and Atem slowly leaned down on top of him, his violet eyes glowing strangely in the semi-darkness for a moment before he closed them, with a look of pure bliss painted across his pretty features.

Confused, Kaiba swallowed thinly and chanced a glance down, seeing Atem's tongue-like penis slowly sliding up his front and giving the base of his dick a fiery lick.

Unprepared for the stream of fire shooting down his chest, Kaiba bit back a gasp and grit his teeth, struggling to keep his eyes open as Atem's upper body stayed glued to his while wonderful waves of pleasure washed over him, causing him to shudder uncontrollably.

They weren't…. moving their bodies, but somehow…. their lower parts…were…moving with minds of their own.

Atem snaked his arms around Kaiba's neck, hanging on for support when a particularly rough rub from Kaiba's arousal had him hovering on the peak of an orgasm, and he curled his body forward instinctively, enjoying Kaiba's hands running up and down his forearms as he came in an explosive rush, panting heavily with his eyes half-lidded as he gazed into Kaiba's pale flushed face.

Fast… Kaiba thought dimly before his body was also assaulted with a joyful heave, and his mind humming happily, shutting off while the blood rushed into his face, stinging his cheeks and ears.
Holy fuck.
This orgasm felt different.
It was a bit…shallow? But it still felt good.

"You see?" Atem panted, brushing the hair away from Kaiba's cheeks, smiling warmly down at his partner. "Now, we can try it again, a different position. If you don't want to look at yourself, we can do it this way."

Kaiba opened his mouth to ask a question, but discovered he was speechless…and hard, still unsatisfied, because he felt himself leak…again. Their fluids were floating in the water between them, and Atem swatted it away with alarming ease.

"We can clean up later," the king said impishly with another fang-glinting smile. "Again."

Breathless, Kaiba once again tried to speak, but his voice left him when Atem's ring-adorned hand came down onto his dick and gave him a tight squeeze. His stomach clenched happily in response and he saw Atem inch away to lift his fins up, and his warm palm began sneaking up the backs of his…thighs, if he had any….and a finger pressed against hole with frightening precision.

Letting out a surprised gasp, it took all of Kaiba's willpower not to fight back, because Atem was doing something...strange, trying to lift his fins to bend him at an angle.

"Tuck your…I believe they're called, knees? Kneecaps? Into your chest," Atem said encouragingly, his cheeks pink with excitement.

Kaiba shook his head and silently obeyed, unsure of where this was going, but he was willing to go along for the ride if an earth-shattering orgasm was at the end of it. Atem leaned over his fins and gazed deeply into his eyes, causing his stomach to churn with happiness, and the mer-king's mouth moved, asking him something.

There was a loud ringing in his ears, and Kaiba blinked. "Repeat that?"

"I'm coming in here," Atem said, his voice shaking uncharacteristically. "I want to. I can't sleep sometimes because I've thought about doing this with you…so much that…I don't know if I'm dreaming now."

Kaiba gave Atem a small smile, craning his neck up to tenderly kiss him, and his heart thumped excitedly at the thought of being wrung out until he forgot his name. He locked one arm around Atem's neck and felt the king pull away for a moment for a breath, their eyes never leaving each other as Atem slowly surged forward and slowly prodded Kaiba's hole before giving it a passionate lick.

Shivering, Kaiba let his breath out slowly, preparing himself for pain, but to his surprise, there was nothing but a warm, steady heat stretching him delightfully, filling him up slowly to the brim until he felt Atem's stomach press tightly against his fins. Oh. F-Fuck.

That felt like heaven. This was nothing compared to being entered in his human hole.

He took that thought back in an instant the moment Atem decided to move. A passionate thrust rocked his body so much, Kaiba swore the bed moved, but he wasn't sure of anything anymore. He was lost, and Atem was curling high inside him, setting his body on fire while his front throbbed with need. Through his haze of pleasure, Kaiba barely noticed Atem's tanned hand reaching down to grab him and give him two fluid strokes, alternating between thrusting into him and rubbing him up and down vigorously. Gasping and heaving, Kaiba threw his head back into the pillow and let Atem do as he pleased, because everything was hot, and heavenly. Every feathery kiss placed across his shoulder, every gentle touch, even the playful pinches on his nipples or soft bites to his neck sent a curling, clenching orgasm ripping through his body, and it never seemed to end. It didn't end. It was different every time, but with just enough familiarity, he could curl his fingers around Atem's arms, which were planted firmly on either side of his head and cum intensely while Atem's face hovered centimeters from his, breathing in his sweet breath as they stayed connected below.

Hot lips trailed down the center of his chest, and Kaiba struggled to pry his eyes open so he could see a wonderful, spiky head underneath his chin, but he gave up when his lids weighed a thousand tons.

Grazing his fangs along Kaiba's hipbone, Atem stared at it so hard, realizing this was Kaiba's sexiest part of his body. That, or his eyes, or his hair…he couldn't decide. It was as if Kaiba was pulling him in deeper, faster, encouraging him to flick the tip of his sensitive member inside his hole, thudding somewhere below his navel and wrenching another shuddering climax from him, and Atem tried to hold out, but the waves of pleasure crashing over him was too much, too fast. Kaiba clenched around him tightly, causing his vision to whiten for a moment while his ears rushed loudly. His body shook with ecstasy as he glanced down at Kaiba, splayed out on the pillows beneath him, and he let himself cum in an enormous, trembling heave, his blood running hot and cold at the same time while Kaiba's hands came up to drag down the front of his chest, shamelessly groping him.

Letting out a laugh, Atem gently extracted himself and collapsed beside Kaiba on the bed, their chests heaving in sync as they tried to catch their breaths.

The air in the room had grown murky, and several stray scales were floating around, suspended a few inches off of the bed.

Kaiba took in all of these details with his heart thundering in his chest, and he closed his eyes contentedly, pulling Atem closer to him and nuzzling his nose into the mer-king's ear, feeling his jewelry poke him uncomfortably. Nice. Just as he'd imagined.

"How was that?" Atem asked nervously, knowing the answer, but he wanted to hear Kaiba say it.

"Good. I'd do it again, but to you," Kaiba said lightly, sifting his fingers through the king's blond bangs. "Keep teaching me these tricks and I'll find a way to surpass you."

"Ha!" Atem grinned, growing wonderfully drowsy. "I encourage you to try."

"Mmmm," Kaiba hummed noncommittally, his stomach growling with hunger, but he ignored it.

There was food, but he was more tired than hungry.

He began drifting off, enjoying the way Atem's claws raked through his hair reassuringly, blanketing him with a calm he yearned for his entire life.
