Diamond Dust

Side Story II

Chapter 32

Fiancé (1)

25 min read

Moonlight filtered in through the large window facing the courtyard, illuminating the kitchen and living room well enough — but that light could not reach past the partition wall into the bedroom.

A dim glow fell vaguely over the bare skin of the two tangled together in the dark.

Liu lay on his back with his knees raised, and Yeehyeon was draped over him — lower body directly in front of Liu's face, fully exposed. Not merely exposed: bent forward as he was, the spread of his ass revealed his entrance between the cheeks, along with his balls and cock, in fine detail.

With their faces buried between each other's legs, the two men freely explored, licked, sucked, and touched every intimate part of the other with their lips, tongues, and hands. It was as if each had forgotten that the other possessed the same basic structure — as if, in terms of their secondary biology, they were opposite sexes. To Liu, Yeehyeon's entrance was something thoroughly mysterious. To Yeehyeon, Liu's cock was the same.

Yeehyeon struggled to swallow the head — which filled his mouth — even a little deeper. But it wasn't just the thickness; the constant flow of pre-cum made it difficult. His mouth was slick all over. Some of it slid down Yeehyeon's throat without permission.

Having continuously swallowed pheromone-laced fluid, Yeehyeon was growing bolder. He felt no shame even though Liu's face was buried between his ass cheeks, doing whatever he wanted to every private part of him.

"Mm… mm… mm… ngh."

A muffled sound escaped Yeehyeon's mouth, blocked as it was by Liu's cock. It sounded almost like a cry for help. The stimulation happening between his legs was too much.

Liu was practically kissing Yeehyeon's entrance. He darted his pointed tongue in and out, curling the tip to gently scrape inside. He also rubbed the opening aggressively with his lips — full and heavy — pressing into the surrounding flesh.

"Ah — mm… oh… mmh."

He couldn't bear the sensation of Liu's tongue spreading flat and wide, aggressively working his entrance and the soft flesh surrounding it.

Yeehyeon gave up on taking more of the head. Instead he stimulated it by pulling it in and out of his mouth. The fluid running down the shaft against Yeehyeon's lips made an embarrassing sound, but it wasn't so different from the sounds coming from between his legs.

"Mmh… ah… mmph."

The ridge of the head scraping the inside of his cheek as it pulled back kept dragging his thoughts to sex. The moment he thought of how it felt when this same cock moved in and out of him, scraping against his sensitive inner walls, Yeehyeon's entrance twitched and tightened.

"Hah… hngh."

Liu didn't miss that moment. He pushed his ring finger deep inside the entrance. Not the index or middle finger — the ring finger. The one wearing the same ring as Yeehyeon.

Yeehyeon's entrance, swallowing the finger whole with only the simple matte band left outside, clenched and sucked at it. Clear, sticky fluid — forced out past the ridge — wet the ring and ran down Liu's hand and wrist.

Hah… hah…

A fierce gleam flashed in Liu's bloodshot eyes. His pheromones — with this stunning view right before him — grew stronger and more potent.

"Nngh… mm… ah — ah… hngh..."

Every time Yeehyeon groaned, the slick, wet walls pulsed and gripped the finger. Liu's cock twitched at the sucking pull drawing him inward. He desperately wanted to drive his cock — swollen so tight it felt like it might burst — deep inside right now. Wanted to move his hips freely, wildly. But the fact that he still held back could only be explained as a miracle born of something close to love.

A deep breath.

One more finger pressed in — then soon two more — until three were filling him.

"Ah… nngh… huu… ah."

Yeehyeon spat the head from between his lips. Liu's cock, released, swung wildly. The column of flesh, kicked up by the momentum, struck Yeehyeon's nose and eyelids before finally standing straight on its own. Pre-cum mixed with saliva stretched thick between his lips and the head.

"Nngh… ah… mm..."

As fingers filled the entrance — which had been opened thoroughly in the shower — Yeehyeon clenched his ass in pure satisfaction. Instinct. Forgetting to pleasure Liu's cock, he twisted his hips and shook them while pressed against Liu's groin.

"Ugh, yes… ahh… ah — "

He whimpered as if pleading, rubbing his cheek against Liu's hair. The base of that cock brushed against the bridge of his nose. Smelling it, seeing its shape — his body surged again. He wanted to suck it, wanted to touch it, wanted to taste it with his tongue. He kept attacking the shaft, licking it, only to collapse again from the pleasure of being worked from behind.

"Hah! Ah! Uh!"

With a broken cry, Yeehyeon slumped forward onto Liu's groin again. Using his wrists, forearms, even his biceps and triceps past the elbows, Liu was pressing into Yeehyeon's depths with the full strength of his arm.

"Ngh! Yes! Yes! Ah! Ah!"

Every time Liu's arm tensed, Yeehyeon's body jolted — as if being shoved from behind. The force was so intense that Yeehyeon lowered his head to look, just to confirm that Liu's forearm really was pressing in that far. That was how much strength he was using.

Even so, Yeehyeon didn't try to close his legs or stop Liu. Instead, he raised his hips higher, rubbed his cheek against Liu's cock, pressed his lips there. Pheromone effect.

Liu — seeing, hearing, and feeling everything Yeehyeon was doing — was also losing his mind.

Every time he thrust his fingers in deep, the pooled fluid splattered everywhere. Droplets scattered across Liu's forehead, eyelids, cheeks, lips, collarbone, chest.

"C-crazy… ah — ah!"

For a moment, Yeehyeon's ass trembled. Another large surge burst out, running down Liu's veined arm all the way past his elbow.

Sparks nearly flew from Liu's eyes. Without withdrawing his fingers, he lifted his head and dove into the entrance. Like a beast that had finally found water after wandering through scorching heat, he clung desperately to Yeehyeon's ass. He licked greedily around the hole his fingers were violating — pressing his tongue flat as if to crush it — and scraped the surrounding flesh with his teeth, sucking hard. Red marks appeared immediately on the tender skin.

"Nngh… mm. Hah… ah… ngh."

Being worked by fingers at the same time as being devoured by a tongue and mouth was more than he could handle. Yeehyeon became afraid that his entire lower body — not just his entrance but his cock, his inner thighs, his stomach — might dissolve entirely.

"Ah… ah. Ahh… uh… ah..."

Yeehyeon instinctively began to crawl forward.

"Ah!"

Useless. The long, firm arms — fingers withdrawing from inside him — immediately wrapped around Yeehyeon's thighs and dragged him back. He grabbed for the sheets as he collapsed onto the mattress, but was helplessly pulled flat, stretched out face-down.

"Mmgh!"

Liu's sharp nose buried itself in the cleft of Yeehyeon's ass, and those lips — exhaling hot breath — sucked repeatedly at the gaping entrance. His smooth tongue crushed through the space between the cheeks.

Yeehyeon's fingers reached out blindly and caught a pillow. He hugged it tightly and buried his face in it.

"Sshh — hah… huuu..."

Liu breathed in deeply, face buried in Yeehyeon's ass. As if savoring it. Then — purr, purr — he shook his head slowly from side to side. Ecstasy radiated from between those cheeks, trembling on either side of him.

"Haa... I could stay here all day."

"I don't want that..."

Yeehyeon's voice was muffled by the pillow.

"Yes you do."

"It's not that..."

"......"

"I want something else. Something different."

"Something else? What kind?"

Knowing full well that Yeehyeon now meant he wanted Liu's cock, Liu asked again anyway. A mischievous yet charged smile spread attractively across his lips.

"What do you want, Yeehyeon? Tell me — I'll give you anything you want."

Looking up at the back of his lover's head — still refusing to show his face — Liu licked the curve of those raised hips with his tongue.

"I genuinely don't know. Teach me. What does Seo Yeehyeon want right now?"

"...Knotting."

"......"

Liu couldn't believe his ears. Slowly, he raised his head from between Yeehyeon's prone thighs. He was no longer smiling.

When Liu had visited the East Sea alone at Yeehyeon's request, he had explained to Yeehyeon's father that his son would likely become an Omega before the year was out.

It was a plan they had made together. To achieve it, they had continued knotting and Changing every time they met.

But the plan had unexpectedly changed afterward.

The two had been planning to move to Bali together when Yeehyeon left The Hands. But Yeehyeon ended up staying longer than scheduled.

Yeehyeon was around 80% expressed at that point. After discussion, the two decided to temporarily halt the Changing process — the remaining 20% to be completed after moving to Bali, so that Yeehyeon wouldn't fully express while they were living apart.

So even though Liu touched him every day for forty days and they had penetrative sex four to five times a week, Liu had never once knotted. Not because he didn't want to. He had endured it with every ounce of his strength.

Every time, he held the base of his cock with three fingers while moving inside Yeehyeon. Because if he drove deep into Diamond Dust and thrust his hips as freely as he wanted, he would never regain control.

Once he entered that state, knotting and Changing were unavoidable. Since it was impossible to regulate the Changing by knotting in Didi, knotting inside Yeehyeon meant both knotting and Changing.

And yet, Yeehyeon was asking him to knot.

Liu propped himself up and raised an arm to roughly wipe his face.

It couldn't be. He must have said it in the heat of pheromones. Some kind of dirty talk.

Even lying prone, Liu stroked the dizzying curve of Yeehyeon's hips — tracing the slender waist and the clean ridge of his back upward. He massaged the balanced shoulders, then gently pulled. Following Liu's lead, Yeehyeon smoothly turned over.

"......"

"......"

Yeehyeon, lying on his back now, was clearly intoxicated by pheromones — but he managed to focus his gaze directly on Liu.

Even so, Liu couldn't do what Yeehyeon was asking. He picked up a towel — completely soaked with slick, changed in color — found a relatively dry spot, and wiped his face. He offered a smile.

“All that earlier buildup in the bathroom went to waste.”

He changed the subject with a light laugh.

Yeehyeon kept his lips pressed firmly together, simply looking up at Liu. His expression was sullen and reproachful, but Liu pretended not to notice. He took another towel — crumpled messily on the sheets — and spread it out neatly beneath Yeehyeon's hips.

"Are you going to stay sulky like that?"

Settling between Yeehyeon's legs, Liu glanced up at him. Then he leaned forward and stroked his lover's sharp jawline.

"Give me a smile with that handsome face. Hmm?"

"What? The handsome one is... Kun."

"I was never called a pretty boy in middle or high school."

If Liu possessed the kind of classic, textbook handsomeness that radiated masculine appeal, Yeehyeon was a modern kind of handsome — fresh, vivid with the energy of his age.

Thick jet-black hair, dark and expressive brows and lashes, long clear eyes, slightly stubborn full lips with a distinct curve, a slender yet firm jaw. Long limbs stretched out with easy grace.

At twenty-five, Yeehyeon was a young man overflowing with refreshing vitality. A handsome face, simple clothes made striking by his build, and a shyness that only made him more appealing. He had undeniably grown into a man since they first met.

Liu marveled anew at Yeehyeon's naked body — stripped down to nothing. Tracing the dizzying straight line from his trim waist to his narrow hips with his fingertips, Liu pushed the head of his cock into Yeehyeon's body.

"Truly... beautiful."

"Ugh... yeah! Haa."

Feeling the heavy, deep thrust of the hard cock, Yeehyeon trembled beneath him. Liu leaned his upper body forward, pressing his groin firmly against Yeehyeon.

"Hah… ah… Mmm.. hah..."

Yeehyeon panted with his eyes wide open. Gripping the sheets against the enormous pressure, he slowly twisted his hips. With each regular pulse — like breath itself — his entrance contracted and opened, drawing more of Liu's cock deeper each time. The sensation was vivid and distinct.

Liu's cock felt thick as a forearm, perhaps? The sensation of his pelvis being forcibly pried open was so real he'd almost thought that. It felt as if Liu filled every space inside him. And yet his senses, completely paralyzed by pheromones, registered no pain even while taking the Alpha's size.

How could I — with no experience, only a Beta — have taken this cock all the way in during my first time with Liu? Why was I, who had been so indifferent to sex, so aggressive from the start in bed with him? How did I endure the Alpha's knotting — something a Beta's body could never withstand — without a single torn wound?

Now I know the reason for all of it.

Because I was Didi.

Because I hadn't been smelling his cologne. I had been drinking his pheromones.

Swoosh — the cock slowly withdrew, and then — smack — drove in all the way.

"Haa! Ugh!"

Yeehyeon gasped, jaw dropped. The sensation of arousal fluid pooled inside him being pushed back to the entrance as the cock filled him was vivid.

With himself fully seated, Liu took three or four deep breaths. Then he pulled back slightly and wrapped his fingers around the base. The foreplay had been long — he began to move violently.

"Haa... ugh, it's, it's so d-deep..."

The rapid thrusting of the shaft inside him, combined with the dense concentration of pheromones, left Yeehyeon struggling to breathe.

"Here — do you feel it?"

With the hand that had been gripping Yeehyeon's hip, Liu used his fingertips to stroke Yeehyeon's lower abdomen, just below his navel. Very gently. Yeehyeon clawed at the edge of the pillow, trying desperately to meet Liu's eyes. Despite being drenched in sweat, Liu was smiled.

"Nngh… ugh! Ah! Ah, uh..."

"This is where Yeehyeon's Triangle Zone is growing."

Yeehyeon looked down at the spot Liu was touching, eyes filling. His lower abdomen — slick and gleaming — pulsed faintly.

"Later... much later... the place where our baby would grow."

Liu said it again more simply, then let out an awkward laugh.

"Haha... Of course, only if Yeehyeon wants it too."

"W-why do you... say it like that?"

"......"

"Of course I want it too."

In that moment, Liu's cock swelled suddenly inside him. The rhythm of his thrusting slowed. Yeehyeon placed his own hand over Liu's hand resting on his stomach.

"I want to see them."

"Our baby?"

Liu managed a strained smile through the sweat on his face.

"Awi's snowball."

"......"

Liu's thrusting stopped completely. The smile on his sweat-dampened face vanished along with it.

Holding Liu's gaze, Yeehyeon's right hand moved downward. He began to touch the place where their bodies were joined — where Liu's cock was buried inside him. Every time he pressed and rubbed, Yeehyeon's bare shoulders rose and fell slowly. He looked like an aroused Omega pleasuring himself. Liu could not take his eyes off him.

Didi — who carried inside him the Triangle Zone where Liu's child would grow — gave an order.

"Make me fully an Omega here."

"We made a promise. We said we'd pick it up again in Bali."

"Do it now..."

"Do you want to make me that kind of man?"

"What kind?"

"...The kind who gets addicted to your pheromones and forces you into being an Omega."

Yeehyeon looked up at Liu in silence for a moment. You don't want to make me that kind of man, do you? Liu was about to close the conversation that way.

"What if I do?"

"...What?"

Liu frowned without realizing it.

"I said I want to make Awi that kind of man."

Yeehyeon, saying it, showed not a single trace of hesitation.

Inside Yeehyeon, Liu's cock twitched and trembled. As if ready to knot at any moment. He couldn't tell if his heart was beating in his chest or in his cock. What was clear was that Yeehyeon's words were igniting something in Liu's instincts.

It was Liu who broke eye contact. He ran his palm over his face and shook his head.

"You're saying things you can't actually handle."

"Kun knows I'm not the kind of person who says things just because I'm swept up in the moment."

"You know this isn't right either."

Liu immediately regretted the slight harshness in his voice. He gripped Yeehyeon's hand — resting over his own — and leaned forward to kiss the back of it.

"If you were to fully express or go into pheromone shock while I'm away... I couldn't bear that, Yeehyeon."

With his head bowed low, Liu pressed his lips against the back of Yeehyeon's hand.

"You said it's still at 80 percent. That it's fine. Marcus said so too."

"There can be exceptions."

"Kun, look at me."

"......"

Liu lifted his head with difficulty, looking pained. Toward him, Yeehyeon extended his other arm. With a small sigh, Liu leaned his upper body further forward. Yeehyeon wrapped both arms around his neck and pulled him close — chest fully against chest. Stubbornly, Liu's left hand still gripped the base of his cock.

Lips pressed to Liu's ear as they held each other, Yeehyeon whispered in a fractured voice.

"I'm different now than I was then. I'm ready."

"Yeehyeon..."

"So change me."

For some reason, Liu got goosebumps. His heart and the corners of his eyes grew suddenly, acutely warm.

Yeehyeon's right hand slid down Liu's side. It slipped between their joined lower bodies and gently took hold of the hand clutching the base of Liu's cock. One by one, Yeehyeon began to uncurl each finger.

"......"

Liu no longer stopped him. Without a word, he looped his right arm behind Yeehyeon's neck and embraced him around the shoulders.

Finally, all fingers were released. Yeehyeon pulled Liu's broad back into his arms.

Deeper. Deeper than ever before. All the way to the end, without any restraint. Liu drove all of himself fully into Yeehyeon's body.

"Hah… ah..."

Yeehyeon's slow exhale trembled faintly. Pheromones spread from that breath. Liu turned his head and kissed Yeehyeon's cheek where he held him in his arms. Then — without any obstruction — he began to move inside Yeehyeon.

The position wasn't unusual. They were simply striving to be pressed closer, to be connected more deeply. Their lower bodies, stomachs, chests, and all eight limbs were tightly tangled. So tightly that no one could undo the knot. Within that firm embrace, only Liu's lower body — pressed down on top — moved back and forth in the dim moonlight.

Liu unleashed the instincts of an Alpha and a Ghost to their fullest. He felt as free as a stallion breaking from its reins to gallop across an open plain. He was not being denied. He was not being excluded. In the arms of the sole Diamond Dust, he was finally understood and accepted.

For a moment, the tips of Yeehyeon's fingers gripping Liu's back turned white.

"Haa, sob! Ku, Kun... it's — it's coming now, it's coming..."

It felt as if the organs in his belly were swelling to bursting.

No — it wasn't Yeehyeon's organs swelling. It was Kun's cock — the Alpha's cock — filling every last space inside Yeehyeon so that not a single drop of semen could escape.

Knotting.

Yeehyeon's eyes went wide, mouth falling open as he struggled for breath. He clawed wildly at the thick back and shoulders pressing down on him. The legs wrapped around Kun's waist thrashed helplessly.

"This… this… kh — sob… k — ah..."

Thump, thump, thump. Boom, boom, boom.

Like the vibration of a massage gun — like a massive speaker playing a symphony at full volume — Kun's cock, swollen tight inside him, trembled violently. The slick pooled between the cock and his inner walls pushed sensation to its peak. Yeehyeon tilted his jaw up, mouth falling slightly open.

"I — I like this... Kun, I like this. I feel like I'm going crazy..."

"You like the knotting, Seo Yeehyeon?"

"I like it. I-I... ugh!"

"That good?"

"Aah, unngh! Ngh! Ugh!"

Yeehyeon was literally coming apart. He rubbed the back of his head against the pillow, writhed his shoulders, twisted his hips. Every movement directly stimulated Liu's cock deep inside him.

"Ahh… yeah! Ah! Keep… keep going… ah — ah!"

Each time Liu's cock trembled, waves of climax crashed over him in succession. The vibration from the knotting felt as if it were shaking and turning over not just his belly but his heart, his mind, his very soul.

"My… stomach's gonna burst, ah! Hah!"

Liu came. The overwhelming pressure — like being struck inside his deepest, most tender place — felt as though it might leave its mark in the Triangle Zone, still so immature.

The pleasure was several times stronger than when they had sex before the Omega transformation, using only that spot deep inside. Yeehyeon cried out like a man burning alive, and at the end of his cries, he sobbed. Liu diligently licked away the tears running down Yeehyeon's cheeks.

"Ku — Kun… ah… ahh — "

Shivering in every limb, Yeehyeon reached for Liu.

"Hey, Yeehyeon-ah. Are you okay? The knotting was a little much — it's been a while, right?"

Hic. Yeehyeon swallowed dryly through his sobs. He blinked his wet eyelids several times, struggling to focus.

"Huu… huu… ngh… I don't want us to break up."

"Yeehyeon-ah?"

"I wish Kun wouldn't go to Seoul, hngh... ah, I wish you wouldn't go."

Then he wrapped both arms tightly around Liu's neck.

"Don't go. Stay by my side."

Liu couldn't believe it. Yeehyeon was always composed in every situation — seemingly wanting nothing, capable of handling anything entirely on his own. While Liu had always found that dependability admirable and felt proud, he had also constantly worried that Yeehyeon pushed himself too hard alone.

There were occasional small childish moments — like asking to trade his strawberry ice cream for chocolate because the chocolate looked better. But Liu had never imagined Seo Yeehyeon acting like this over something already agreed upon and planned. Whining about not wanting to part, not wanting to go back — that had always been Liu's role.

Even soaked in pheromones, even half out of his mind from the knotting — for Yeehyeon to act this way felt more painful and sad than happy. Though deeply touching, and endearing beyond measure.

Liu wrapped both arms fully around Yeehyeon, pressing kiss after kiss to his tear-damp face.

"I won't go, Yeehyeon. I promised you before — if you told me not to go, I wouldn't. Didn't I?"

How can I love you more? How can I exist closer to you?

If you were to get pregnant — if a child that looked like both of us grew inside you — would that fill this aching, this restlessness even a little? Would I feel more connected to you?

He supported Yeehyeon's back and gently helped him sit up — pulling him onto his own thigh, holding him close, rocking him slowly as if soothing a child. Yeehyeon, cheek pressed hard against Liu's cheek, sniffled and whispered.

"Don't go."

Until his body shattered. Until his soul vibrated. He wanted to cry it with his whole body, his whole soul: Marry me.
