Chapter 4

Once the initial, urgent heat was quenched, none of them spoke, mirroring their momentary lack of coherent thoughts. The combined warmth of their bodies protected them from the chill of the room, as Mokuba's head was resting on Seto's shoulder, his upper body pressed along his brother's side and legs entangled and heavy after their first, intense lovemaking, the evidence of which was the sweet ache in his lower body and the slick feeling Mokuba tried to ignore. His open palm laid on his big brother's chest, counting the inhale and exhale, until both their breaths returned to normal.

This is where Mokuba could swear he heard the gears inside Seto's head start spinning – the muscles under his palm tensed, and legs shifted. The younger would have given everything to prolong this moment of peace, but he had to move as Seto lifted himself in a sitting position, avoiding his gaze.

Seto opened his mouth, but Mokuba was quicker.

"Stop overthinking, Nii-sama."

His brother turned around, ready to argue, but Mokuba took this opportunity to seal his mouth with his own, shamelessly invading him with his tongue. Seto immediately surrendered, and a stifled sound escaped his throat – half-protest, half-encouragement. Yet the older man did not protest anymore, as Mokuba pressed his hands on Seto's shoulders and pushed him backward on the oversized bed, climbing on top.

Looking at his brother from above, it did not escape Mokuba how Seto's hands hovered just an inch from his sides, eager to touch but not daring, and the conflicted gaze, with which his brother looked up at him and it puzzled Mokuba more than anything else in his life – did Seto not feel the same overwhelming, overflowing emotions, the sense of absolute rightness of what they were doing?

The thought terrified him.

Mokuba cupped his brother's cheek and rushed down into another kiss without closing his eyes, clumsily trying to convey how much he loved Seto, how much he did not want this to end, desperately searching for the answer in Seto's blue eyes.

And he got it – with a moan Seto surrendered and dropped his guard, his hands winding around Mokuba's middle, pressing him down onto himself, elbows on each side of his head. His expression washed away all of Mokuba's fears – the same raw emotions that raged inside him were in plain sight on Seto's face, in every frantic touch, in every gasp of air between the jagged, sloppy kisses.

Encouraged by Seto's willingness, Mokuba explored his mouth, carefully memorizing the way Seto felt and tasted. Their tongues did not yet seem to know what to do with each other and the momentary confusion made them both breakaway and laugh, forehead to forehead, and it was the best sound Mokuba had ever heard.

They were here, together, kissing and loving each other. It was so unbelievable, like a dream. A dream Mokuba never wanted to wake up from.

Their second attempt at kissing was more successful, and a shudder ran through Mokuba's entire body as Seto's hands ran down his back and tentatively grabbed his ass. The once satisfied hunger returned tenfold – both felt it growing between them, pressing against each other. Mokuba rose from his position and shifted his knees to be at Seto's sides, all while watching his brother follow his every move from below.

Locking their eyes together, Mokuba ran one of his hands slowly down Seto's chest and abdomen, giving special attention to the well-formed muscles of his six-pack. Meanwhile, his other hand reached behind himself, and Mokuba grinned, as Seto grabbed his ass more firmly and pulled his cheeks apart, assisting him in stretching himself.

There was lube left from last time, but he still took his time, carefully watching Seto's open expression – his blue pupils were blown wide, indicating arousal, but there was also amazement and worship and devotion all mixed together and Mokuba couldn't get enough of it, drinking it all up like a man lost in the desert would drink water from an oasis.

Afraid to break eye contact, Mokuba blindly reached further behind himself and grabbed Seto's fully grown erection. His brother gasped, blue eyes half-lidded, as Mokuba gave him three slow pulls before he lined it with his entrance.

The head breaching the muscle ring was the perfect combination of sweet ache and overwhelming joy at feeling his brother inside again, in the most sacred and intimate ways possible. Mokuba let out a moan of pleasure, as he slowly sank further down on his brother's length, savoring the sensations, and enjoying the sight of Seto's mouth open in a silent 'oh' and his head thrown back, revealing the column of his throat, every muscle in the older man's body tensed up.

Their first time earlier was a frantic mess, wherein now every inch more of the incredibly tight hotness around him drove Seto insane. His fingers involuntarily sank even deeper into the soft flesh of Mokuba's ass, but no matter how far gone Seto was, he didn't attempt to control his brother's movements.

Letting Mokuba take over, giving up every ounce of control, losing himself in the indescribable feeling of him in his arms, him all around not only his member, but Seto's heart - his innermost core -, and sinking even deeper, selflessly taking all of Seto in without even a pause.

As Mokuba was finally fully seated, his face was flushed and his breath became irregular, his skin was damp with sweat and his long black strands clung to his shoulders in strange patterns.

Seto memorized the erotic view above him, taking long calculated breaths to prevent himself from finishing right then and there – knowing he was deep inside Mokuba, knowing that they were now connected on all possible levels two people can connect – all this was almost enough to send Seto over the edge, but he wasn't Seto Kaiba for nothing and exerted his self-control, letting his hands wander instead, down Mokuba's thighs.

This was when Seto realized his brother was trembling.

Immediately worry overshadowed everything else and Seto braced himself with one hand and carefully rose with his upper body to be closer to his brother's face, cupping Mokuba's cheek, searching beloved features for a sign of discomfort.

"Mokuba… are you alright?" he whispered hoarsely. His thumb caressed his brother's skin, pushing black hair away to have a better look. Mokuba opened his eyes and smiled down at Seto, and the amount of love in his violet eyes took Seto's breath away, making his heart skip a beat. Mokuba leaned closer and framed Seto's face with his hands, pressing their foreheads together.

"I've never been better, Seto," and their mouths connected again, slow and tender and perfect, wordlessly passing an endless 'I love you' and 'You are my everything' between them.

Seto encircled Mokuba's body with his arms, pulling him even closer until skin was glued to skin, and there was no difference between their bodies anymore, nor between their souls. Just the formation of love, the formation of two being one.

Still caught in the endless game of tongues, Mokuba rocked his hips once in a calculated way and elicited a surprised moan from Seto. Repeated the movement and Seto had to stifle his moans on Mokuba's shoulder, while his fingers involuntarily left red gashes across Mokuba's back.

However, as Seto suddenly fell back to the bed and buckled his hips upwards, it was Mokuba's turn to whimper from the friction, and he braced himself on Seto's muscular chest.

One glance at each other and they both knew what to do - Mokuba raised himself, letting Seto's member almost out of his body, before slamming back down, and Seto met his movement from below, both shuddering at the wholly new sensations, as Seto's member hit the sweet spot inside Mokuba and made the younger see stars with each thrust.

Violet and blue eyes never left each other, as their bodies rocked together in unison, and the room filled with sounds of skin slapping against skin, heavy irregular breathing, moans and incoherent words whispered mindlessly against the other's lips in between frantic half-kisses.

Seto found Mokuba's member, fully erect and leaking against his abdomen, and reverently took it in his hand, squeezing slightly. His brother immediately lost the rhythm of their movement and regarded Seto with wide eyes from above.

He pulled up and down, setting a merciless pace, and Mokuba whimpered, throwing his head backward. Not allowing his brother even a moment's reprise, Seto resumed the thrusts of his hips up and down, out and back inside the heavenly hot, tight body of his lover. Each thrust felt like a holy revelation because neither had ever felt even remotely close to this all-consuming pleasure, neither had ever felt as complete and whole and understood as they did in this moment.

Realizing that he won't last much longer, and neither would Mokuba, Seto pulled him down again, before he rolled them both over. Now on top, Mokuba's legs around his waist, and still seated deep inside is brother, Seto paused and enjoyed the sight of the other's flushed face and open mouth, damp glistening skin and half-lidded eyes full of love, and Seto's heart suddenly overflowed with emotion, threatening to tear his chest open from the inside.

I love you, more than anything else in the world. The words stuck in his throat, and even if he could have said them, they felt wholly insufficient to describe what he felt for Mokuba.

Instead, he dove down, trying to translate his overwhelming emotions into a kiss that lasted an eternity and left them both breathless and smiling at each other in understanding.

Then Seto slowly pulled out, and Mokuba let out a whine at the loss, but soon enough started panting at the sloppy kisses Seto was leaving all the way down from his throat to the collarbone. The elder's hands roamed at Mokuba's sides, exploring every inch of the pale skin and hidden muscles underneath, taking his sweet time.

Seto's hot mouth moved further down and down his upper body, leaving a trail of saliva all over his skin, and Mokuba threw his head backward, panting heavily, closing his eyes, enjoying every second of this sweet torture. Suddenly, there was a fist around his member and he gasped in surprise again, as Seto's tongue shyly lapped at the tip.

He watched from above, as Seto took his erection fully into his mouth, pressing his lips around the base of the shaft. He doubted Seto knew how unbelievably hot he looked stuffed to the brim with his erection, and a trail of saliva trickling down his chin. Seto's own member was proudly hard and twitching between his legs.

Seto's wet hot mouth moving up and down, his tongue twirling around his shaft, and the lips pressing tightly almost drove Mokuba out of his mind, and he had to collect himself not to come.

"Fuck! Seto!" Mokuba buried his fingers in his brother's brown hair, massaging his scalp and coaxing a contented moan from the elder. "I… Ah! Won't last…! Seto, please!" He didn't even know what he was begging for, his mind was completely offline, his entire being concentrated around his member in Seto's mouth and the agonizing movement, pressure, wetness, heat.

Mokuba was so far gone that he didn't immediately realize that Seto let go and moved back up until his brother's hand tenderly caressed his cheek. He opened his eyes to the beloved face, a soft smile and blue eyes full of warmth.

"How do you want me?"

Mokuba's lips formed a bright smile, and with one smooth motion, he turned around onto his stomach, arching his hips upwards. He wanted to feel his brother inside again, wanted to become one with Seto until both of them couldn't hold it back anymore.

Seto pressed his erection to Mokuba's entrance and slowly pushed inside until he was once again seated deep inside, and his front was plastered all over Mokuba's back, pressing his brother's body into the mattress. He took Mokuba's hand and intertwined their fingers together, placing a kiss on his cheek, before he started mercilessly thrusting into his pliant, welcoming body and pumping his member in time with the movements.

Neither of them lasted long after that, but Mokuba was the first to spill himself all over Seto's fingers, crying his brother's name into the mattress. His whole body tensed up, closing impossibly tight around Seto, and taking his brother with him over the edge. With one last powerful thrust, Seto spent himself deep inside, riding the high, before he broke down on top of Mokuba.

His whole body trembled, but he still supported himself on his elbows so as not to crush his brother with his weight, and shifted to the side, panting into the black mane, placing butterfly kisses on Mokuba's neck. The younger one seemed as exhausted as him, but he still managed to turn his head towards Seto to kiss him lazily. His body followed suit, and Mokuba snuggled into Seto's welcoming arms.

Both deeply satisfied and completely spent, all they were able to do for the next few minutes was breathe. Mokuba's arm wound itself around Seto's waist and drew lazy patterns across his back, while Seto had his clean hand tangled in his brother's long hair, carefully working out the knots. Soon they ought to get up and clean themselves, change the sheets, but not now.

Now they rested with their hearts beating in perfect harmony.

Mokuba woke up to a cold bed and an empty room. It was late in the morning, but he really wanted to wake up in Seto's arms. He let out the air in his lungs. Was last night even real? Did he and Seto really kiss?

'Did we really…Nii-sama and me…. have sex?' Mokuba tried to process all of last night's events in the hazy way they occurred but he knew he felt Nii-sama. Just like he always wanted. Always dreamed. Except last night wasn't a dream. It was real.

The messy silk sheets could testify to that and the pillows even smelled like Seto. Mokuba tried to move but he was sore. Definitely not a dream.

The chill air hit his skin harsher than any morning before. He quickly showered in Seto's bathroom and used his soap and shampoo. Then put on Seto's shirt half-buttoned and his own pants before heading downstairs.

He wasn't there.

"Are you just going to avoid me forever?" Mokuba said, lying down on the sofa while he waited for Seto to come home.

Three days had already passed since that night.

His brother refused to look at him. He kept each door locked. Wouldn't answer calls or texts. Every time Mokuba woke up, his brother had already left for work. At work, his brother wouldn't give him a chance to be alone. There was always someone there. And Mokuba couldn't work like this. Being ignored or worse, constantly being avoided.

So, he stopped going to work. But no one came by to see him. Emails. His boss assumed since he'd be working from home now to send him emails of the company's latest progress with assignments and projects. Strictly business. How cruel.

Mokuba closed his eyes. He still felt his brother's arms wrapped tightly around his bare skin. Strong and secure, as if nothing could hurt him when he was in his Nii-sama's warm embrace. The way their bodies connected…except he's alone now. And it's very cold.

Mokuba started waiting for Seto to come home by the main entrance. He often fell asleep on the couch. Some nights he'd stay awake till midnight, 2 am, but no matter the time he never caught his brother. Even though he always woke up with a blanket that he didn't have before.

This time though, Mokuba wasn't waiting in the living room.

"Go to your own room," was what he expected Seto to say. Footsteps halted as if the black silhouette was pondering on what course of action to take next.

His brother put down his briefcase and began taking off his tie as if he never heard anything. The silence was deafening Mokuba. It was breaking the internal belief that he always held, and with each wordless minute that ticked by was pricking his heart. Seto didn't care about him anymore.

"We can't do this."

It felt worse. Like a knife straight to the unbreakable red string, he thought had become golden.

He always knew they walked a very thin line. Through all his trials and tribulations Mokuba wouldn't let the threads become undone.

"Nii-sama…please." 'Don't say that.'

But Seto had crossed a line this time. And just hearing Mokuba say that- how he was his beloved Nii-sama. His voice sent electricity through Seto's body with reminiscences of that night.

"Nii-sama please! Ah!" He thrusted harder.

Mokuba wouldn't always stay a kid, he knew that. But what they did, they could never undo.

They were brothers. A fact that bonded them was now the same reason that threatened to break them. All because Seto had relinquished control and given in to carnal desires that should have never been there in the first place.

Even in the dark, their eyes couldn't remain hidden from emotion. Seto wished he hadn't looked as Mokuba's wide gaze swelled up.

"Mokuba- " It was cruel.

"Stop. Just go."

The world is a cruel place.

That's not what he really wanted to say. He just wanted to run his thumb along his cheek and wipe those tears. When you really love someone, they say, let them go. Mokuba should find someone else. Seto unconsciously gritted his teeth. And settle down and have children. Like a normal person.

The door didn't close quietly, it slammed shut.

Seto couldn't sleep that night. Or the nights before. But tonight- he didn't know what kept him up more. The thought of Mokuba moving on to someone else or the dirty deed he indulged himself in now wreaked havoc in his mind.

Every time he closed his eyes, an image appeared. Flowy long black locks, pale face, familiar eyes, the sweetest smile, just for him.

'I keep doing what I said I would never do again. I know I said I'll change even though we both know I'll always stay this way. I just know no one else is as good as you are to me.'

Dark blue eyes felt tired.
