Confined Pheromone

Siwoo, who had Sanho’s body trapped between his arms, buried his face in Sanho’s nape with a fierce urgency.

“Ugh…!”

The alpha’s teeth, bared like a beast, hurriedly licked Sanho’s white nape. Perhaps it would be more fitting to say he was biting. It wasn’t enough to tear the skin, but it was sufficient to leave a red bruise. As his lips made contact with the skin, pheromones surged forth in a wave.

“Grr.”

Siwoo’s arms, which held Sanho tightly, began to tremble. His fists, gripping the bed sheets, shook as well. While he licked Sanho’s slender nape as if he were thirsty, it was also a manifestation of his effort to hold back.

His large hand gripped the neckline of Sanho’s white linen top roughly, as if to tear it apart. Just as the sound of threads being ripped was heard, Siwoo barely managed to pull away from Sanho slowly.

“This pheromone—”

“Senior?”

Having bitten down so hard, Siwoo looked down at Sanho with a contorted face. He barely managed to speak in a low voice, like a growling beast.

“This pheromone, is it yours?”

“…….”

“You’re an omega?”

Though he had finally pulled away from Sanho, it was in vain as Sanho slowly wrapped his arms around Siwoo’s nape. The force pulling him forward brought Siwoo’s upper body close to Sanho once more. The warm brown of his pupils, which had returned for a moment, began to glow red again.

“Senior.”

“What are you, exactly?”

“Why are you holding back?”

“What do you mean….”

“Do you not like me that much?”

Siwoo bit his lip hard. If he didn’t bite his own lip, it felt like he would swallow Sanho’s softly whispering lips right away. But no matter how much he tried to hold back, it was futile. Sanho bent his knees and rubbed against Siwoo’s lower body.

And then, with a thud.

As Sanho’s ankle lifted, the shackles that had been wrapped around it fell to the floor.

Clank.

Even amidst the haze, Siwoo looked up at the leather shackles that had fallen at his feet. Shackles that seemed impossible to come undone. But those shackles had come loose with Sanho’s light movement. It was absurdly easy. Is this even possible…?

“How did that come undone—”

No, it wasn’t that it had come undone. It was clear that the locking mechanism’s teeth had been missing from the start. The lock that had merely seemed to be closed was gaping wide open.

Siwoo recalled that he had only checked the shackles on his own ankle. He hadn’t actually touched or confirmed Sanho’s cold shackles with his hands. As he thought back, Sanho had only reached out to him a moment ago and had been sitting on the bed, not walking or moving. There was a reason for that. If there was too much movement, the shackles that weren’t tied in the first place might come undone. Just like now.

Glancing at the shackles that had fallen from his ankle, Sanho raised his gaze to Siwoo. He noticed Siwoo’s furrowed brow directed at the fallen shackles.

Siwoo had grasped the situation.

As he realized the obvious truth, Sanho’s porcelain doll-like face momentarily shook. But soon, the corners of his red lips curled up in a crescent.

“Oh dear, I’ve been found out already.”

It was a voice that feigned amusement. Sanho, with a relaxed gesture, pulled Siwoo’s nape a little closer to him. He briefly gazed at Siwoo’s lips, stained with blood from being caught between his teeth.

“What’s the reason for holding back so desperately?”

“…Ugh.”

“You could just do what you want.”

Sanho flicked his tongue and licked over Siwoo’s lips. It was an act reminiscent of licking whipped cream. While it wasn’t heavily sexual in nuance, it was still a severe stimulation for Siwoo.

“Do you know that you’re about to burst right now?”

“…Don’t.”

“It’s incredibly hot.”

Sanho’s round knees blatantly rubbed against Siwoo’s lower body. Blood surged beneath the soft caress. Siwoo was well aware that his arousal was growing like a beast in heat.

He wanted to recklessly thrust himself into the fragrant body before him, leaving behind his white rationality. Wildly, roughly. No pheromone had ever stirred such desire within him. He wanted to ravage that body. The moist, wet flesh would open gently, and the hot interior would greedily suck him in. The wet lips would spill out lewd moans and sweet breaths.

But he couldn’t do that.

“Why can’t I do anything when an omega in heat is spreading his legs right in front of me?”

But why was it not possible?

As if a light bulb had burst, his reason flickered out in an instant. With a growl rumbling in his throat, Siwoo lunged at Sanho.

It began with their lips. Sanho’s slightly parted lips welcomed Siwoo’s tongue as if they had been waiting. Siwoo’s large hand cradled the back of Sanho’s head. He roughly pushed aside the hair covering Sanho’s forehead with his thumb and invaded his mouth. It felt like biting into a plump, juicy fruit. The wetness of the oral mucosa was hot, and the flicking tongue was rich. Sweet saliva, so sweet it could be endlessly devoured, oozed out at the corners of their mouths. As Siwoo pressed his tongue against Sanho’s palate, Sanho’s hands, which were wrapped around Siwoo’s nape, trembled slightly.

“Ha, Senior….”

His voice, heated with pleasure, was lewd. Siwoo roughly grabbed Sanho’s crumpled top.

“Ugh.”

With a single motion, the top was torn apart. Though it was thin material to begin with, the force was enough to rip it apart in an instant. Through the wide-open gap of the top, Sanho’s white chest was revealed. Siwoo licked down along Sanho’s neck and sucked on the hollowed-out part of his collarbone. The wet sound of friction was unmistakably loud. His teeth, sharp like a beast, sank into the straight collarbone.

“Ugh, it hurts. Senior.”

The fingertips of Siwoo, who held Sanho’s head, tightened with force. He didn’t want to hurt him… not like this. Even though he had lost control of his reason, Siwoo hesitated for a moment.

“It’s okay. More, do it more.”

Once again, his sharp teeth bit into the tender flesh of the collarbone. Haah, haah, heated breaths burst forth from beside his head. The violent pheromones began to change gradually. Until now, they had been aggressively stabbing, but now they were caressing languidly. The omega, the source of the pheromones, was likely excited as well. The sensation was softer, but for the aroused alpha, this was even more stimulating.

Siwoo’s tongue licked the long scar beneath the collarbone. Sanho suddenly shuddered his shoulders and tilted his neck back. A wet gasp escaped him. In that moment, Siwoo’s eyes widened. As he thrust his waist hard, Sanho’s legs spread wide open. The hot, solid flesh pressed against not only his inner thighs but also his perineum. The two legs flailed in the air. Even though both were still wearing bottoms, the exposed flesh beneath the thin fabric felt strangely erotic.

As Siwoo thrust deeply, he pulled Sanho’s head even tighter. His other hand slipped between the clothes, exploring the flat abdomen. After a while, his hand slowly crawled upward. Finally, when Siwoo’s fingertips touched the areola, a soft moan escaped.

“Touch me more. More….”

The lips that had been licking the collarbone slid down. They touched the perky nipple. It looked plump and reddish, almost like a cherry. Siwoo pressed his tongue against the round fruit, squeezing it. At the same time, he scratched the other nipple with his fingernail.

“Ah, haah…! Ugh, Senior…!”

Obscene moans spilled out in a continuous stream. Sanho’s waist dipped and bucked. As Siwoo sucked hard on the nipple, Sanho’s waist arched even deeper. Sanho’s hands tangled in Siwoo’s hair, frantically tugging.

It was sweet, and even sweeter. He bit down and chewed, pressing with his tongue. He wanted to keep sucking on this sweet fruit. He wanted to take the swollen nipple into his mouth, roll it around, chew it to his heart’s content, and thrust his waist wildly. Each time, he wanted to inhale the hot breath that would burst forth in sync with his movements, over and over again.

But.

“…Hah.”

But he couldn’t do that. He shouldn’t do that.

Siwoo pulled his lips away from Sanho’s chest, panting heavily. The droplet of saliva that had formed at the tip of the swollen nipple stretched like a silver thread before finally snapping. Hah, hah, heaving breaths, Siwoo’s face, furrowed in concentration, was gazed at by Sanho.

Sanho’s white cheeks were slightly flushed. His droopy eyes, rosy nose, and the tips of his ears and nape were all blooming with heat. The arousal in his eyes and his disheveled face could heat anyone’s core, not just an omega or due to pheromones. Anyone would feel that way.

Yet, he still had to hold back.

“…Should I at least applaud?”

“…Sanho.”

“You’re impressive, Senior. To be able to hold back even in this situation.”

Sanho slowly rose from his position. Siwoo instinctively pulled back. Watching Sanho struggle to distance himself, he let out a self-deprecating laugh.

“Anyone would think I’m some kind of germ.”

“…It’s not that.”

“Then what is it?”

Siwoo leaned back a little more, covering his eyes with his hand.

“I can’t… I can’t just touch you like this.”

The mating of an alpha and omega was natural. Instinctively, they were bound to be drawn to each other. Moreover, it was Sanho who had seduced him. It was Sanho who had openly released pheromones and had directly begun to touch him first. Saying he couldn’t just touch him was merely a mirage of self-justification. Siwoo knew that, but instinctively, he blurted out what his mind was telling him. I can’t touch you. The smile that had been self-deprecating on Sanho’s lips hardened.

‘I can’t just touch you. I, at least, must not do that.’

Had I ever said something similar before? Had I ever been so cautious about touching this boy? Siwoo slowly lowered the hand that had been covering his eyes. Sanho’s stiffened face seemed to overlap with a past image. The flushed face of Sanho returned to a smooth, porcelain doll-like expression, dry and empty. For a moment, it seemed like a look of sadness or perhaps anger flickered across his face, but it quickly vanished.

“…….”

Sanho lowered his head, adjusting his torn top. Though the red marks left by Siwoo’s reckless actions were visible everywhere, the long scar beneath the collarbone drew even more attention. The moment Siwoo’s lips touched that scar, the shuddering of Sanho’s shoulders was vivid. Finally, Sanho lifted his head to look at Siwoo.

“Lie down.”

Sanho stood up from his place without hesitation. Siwoo, who had been standing close to the bed where he had been tied, reached out desperately toward Sanho, who was trying to leave.

There were still so many things he needed to ask…!

But he couldn’t easily touch Sanho. It was clear he would lose control again. As he watched Siwoo’s arm drop down, Sanho smiled softly.

“If you can’t release all this pheromone after getting covered in it.”

His gaze, which had blatantly scanned below, was drawn back up to Siwoo’s face.

“You know what happens, right?”

“…….”

“So just lie down. I’ll bring you some medicine.”

The pheromones began to be gradually contained. The breath that had been rising to his chin slowly found its rhythm again. Feeling himself returning to a normal pulse, Siwoo looked at Sanho. Sanho kicked the toothless leather shackles that had been around his ankle with his toes and turned his body without hesitation.

“Why are you doing this to me?”

However, at Siwoo’s broken voice, Sanho couldn’t take a step and slowly turned back again.

“What do you want from me?”

Sanho stared at Siwoo for a moment.

“If I say it, will you listen?”

That wasn’t a question. Without giving Siwoo a chance to respond, Sanho turned back again. He stood in front of the white-painted door and grasped the doorknob, turning it. With a clank, the doorknob turned as if it were a lie. The door, which seemed like it wouldn’t let a single ray of light through, opened surprisingly easily.

“Wait, just…!”

As Sanho tried to leave the room, Siwoo hurriedly grabbed him. Now that the door was open, it might be the only chance to escape this place. A thud and the clanking of chains echoed simultaneously.

“Ah…!”
