As soon as they arrived at Kim Ju-hwan’s house, he brought out the familiar aluminum case. Jeong-min sighed and reached out. However, the case he thought he could grab immediately remained in Kim Ju-hwan’s hand.
“What are you doing?”
Kim Ju-hwan was silently staring at Jeong-min’s hand. It had been fine until a moment ago, but it was trembling again. It seems giving an injection with this hand is out of the question. Jeong-min clicked his tongue as if it couldn’t be helped and rolled up his sleeve.
“Kim Ju-hwan, give it to me quickly. I’m tired.”
“Are you… not afraid?”
“What?”
Suddenly, what fear? Jeong-min looked at Kim Ju-hwan. A dark shadow cast over his face as he gripped the aluminum case as if to crush it.
“Next time, in severe cases, it could lead to full-body paralysis. Are you still not afraid?”
“What? Does your company make drugs that badly?”
“Pardon?”
“I believe that among the drugs that went to clinical trials at Cal Front, there has never been a single casualty. Was that a lie?”
“That is true. Until now, such severe cases…”
While answering Jeong-min, Kim Ju-hwan seemed to realize something and looked at him. There was no hesitation in Jeong-min’s eyes. It was not only the will to get this done but also a deep trust in Cal Front, the company that made the drug.
“Then isn’t it fine? So give it to me quickly.”
Kim Ju-hwan felt foolish for having hesitated even slightly. No, anyone would think that way seeing those trembling hands.
“Still, if there are side effects, tell me first.”
“I will.”
Perhaps his anger had finally subsided, as the sharp atmosphere from before seemed to have softened. Kim Ju-hwan sat beside Jeong-min and handed over the aluminum case. With a click, it opened to reveal an injection and four pills. There were two more pills than what he had taken before.
“It’s been further improved. It will also calm the hand tremors to some extent. But this is still only a temporary measure. To identify the exact cause, you’ll have to undergo a test at least once.”
He was thinking about it quite seriously? Jeong-min was surprised, but he intentionally didn’t show it.
“Ah…”
Jeong-min took the pills first and then received the injection in his arm. It wasn’t like this the second time, but perhaps because the drug had changed, heat began to spread from the injection site, and his entire body became hot with fever. It felt like the administration of a contrast agent used during a CT scan.
“Ugh… ugh…”
No. It was more intense. Jeong-min twisted his body slightly at the heat he felt particularly below his navel.
“Sunbae… the corners of your eyes are red.”
His face was flushed with heat. Kim Ju-hwan took the syringe from Jeong-min’s hand and placed it on the table. Then he carefully observed Jeong-min’s condition. His face was burning red. It was to the point where it felt like an illusion that he was shedding tears, even though none had formed.
“This drug…”
He tried to say it was strange, but Jeong-min bit his lip at the tingling sensation below. Kim Ju-hwan touched the corners of Jeong-min’s eyes and then moved his hand down to firmly grasp Jeong-min’s trembling hand. But he did nothing more. The man who had put him in the car as if he would pounce on him immediately was now just sitting there leisurely, watching Jeong-min breathe heavily.
“What…”
“What are you doing?” I almost asked, but I kept my mouth shut. For some reason, it felt like a blow to my pride to be the first one to speak.
As time passed, the effect of the drug didn’t wear off; instead, it felt as if heat was being infused into every single cell of my body. I could feel my member gradually stirring. This is driving me crazy. I want to undo my buckle right now, pull it out, and stroke it with my hand. A surging desire to bury myself in something rose within me.
It’s not even a rut—I wondered why my body was getting this excited, when suddenly Kim Ju-hwan, who had been holding my hand, bit the back of it. His touch felt more like stimulation than pain. But that was it; Kim Ju-hwan didn’t move any further.
‘I can’t. I can’t stand it.’
Jeong-min undid his buckle. As soon as his member, which had been stiflingly trapped, popped out, he grabbed it and began to stroke it.
“Ah…”
Moving his hand as the heat of his body guided him made him feel a bit better, but it still wasn’t enough. Something more—
“Sunbae, I guess you’re not embarrassed to show me that side of you anymore?”
He heard Kim Ju-hwan’s laugh. Jeong-min frowned at those words and spoke.
“Me? At this point?”
If he thought he’d be embarrassed, he wouldn’t have started this in the first place. After already showing everything, including his hole, what did it matter?
“I suppose…”
More than that, Jeong-min was annoyed by how composed Kim Ju-hwan was. What exactly was he trying to do? The second time was unavoidable, but shouldn’t they do it today, the third time? If so, would he be able to become an Omega? While it would be better not to do it if possible, he was actually anxious. Anxious that he might remain incomplete.
“Your hand stopped, Sunbae.”
Was it because he was thinking too much? The movement of his hand had ceased. Kim Ju-hwan’s hand reached down and lightly flicked Jeong-min’s member.
‘Fuck…’
Jeong-min grabbed Kim Ju-hwan by the collar and pulled him close.
“Are you going to do it or not?”
“If you promise.”
“Promise what?”
“That you…”
Kim Ju-hwan gripped Jeong-min’s member and stroked it softly.
“If any problems arise regarding the drugs in the future, you’ll come to me first.”
He blocked the glans and stroked downward, leading him to crave stronger stimulation.
“A promise that you’ll tell me first.”
“You’re still on— ugh!”
Kim Ju-hwan gripped Jeong-min’s member tightly.
“I’m narrow-minded. Promise me.”
“Fine. Fine! I’ll prioritize you over Doctor Kim! Happy?”
“Even before Yu Shin-woo.”
“…”
“Your answer?”
Whether it was the low voice whispering in his ear acting as a catalyst, his body flinched. He felt like he was going crazy. He could feel his body changing. He wanted to do it now. Whether it was the front or the back, he just wanted to do something.
“I said I would—!!”
Just as he was about to finish the sentence, Kim Ju-hwan grabbed Jeong-min’s arm and stood up abruptly. It felt like déjà vu. So, he braced himself. He expected it to be a terrible night. However, contrary to his expectations, Kim Ju-hwan laid Jeong-min on the bed, stood up, and brought something over. It was a paper bag stamped with the research institute’s logo.
“Ah…”
As he overturned the bag, the gel, condoms, and muscle relaxants he had received from Doctor Kim tumbled onto the bed.
“I wondered why you were clutching those so preciously back then. You left them behind, so I took a look.”
“Doctor Kim gave them to me.”
“I know. And I know why he gave them.”
Kim Ju-hwan popped open a single muscle relaxant pill.
“Here, take this.”
Jeong-min stared blankly at the pill held in that hand.
“It’s safe to take, so hurry. It’ll make it more comfortable for you, Sunbae.”
When Jeong-min opened his mouth slightly, Kim Ju-hwan inserted a finger to press down his tongue and placed the pill on top. As the finger was withdrawn, Jeong-min slowly swallowed and let out a deep breath.
“Today, in my heart, I want to drive it in deeper than before, but I’ll be gentle with you. Since that seems to be your preference, Sunbae.”
“Why are you talking so much today?”
Jeong-min was practically at his limit. Perhaps because he had just taken the muscle relaxant, the strength had drained from his body. He was at a point where he would follow without resistance even if Kim Ju-hwan grabbed and spread his legs right now.
Honestly, he wanted to tell him to just fuck him immediately. It wasn’t because his hole was tingling. As an Alpha, that was impossible. He just wanted to release this heat trapped in his body somehow.
But as always, Kim Ju-hwan did not move according to Shin Jeong-min’s wishes.
“Ugh…”
He didn’t know why the other was touching, kneading, and sucking on his chest, where he felt absolutely nothing. It only felt painful and unpleasant due to the friction of the tongue. Even as he kept signaling him to stop and pushed away Kim Ju-hwan’s head from his chest, he continued to suck on it regardless.
“Stop it!”
“Why? Once you become an Omega, your chest will be the first thing to become sensitive.”
Jeong-min recalled the Omegas he had slept with in the past. Now that he thought about it, that was true. Those Omegas liked having their chests touched and sucked. He had thought it was just a simple preference.
“You have a doubting look in your eyes.”
Kim Ju-hwan smiled and scratched Jeong-min’s nipple with his finger.
“Male Omegas don’t have well-developed mammary glands, so the probability of producing breast milk is low… but still, the chest grows slightly when they get pregnant. Because they are influenced by hormones, they become sensitive. So, shouldn’t you develop your chest in advance, Sunbae?”
He didn’t want to develop that area right now, nor did he desire to. He thought that was a problem to consider once he actually became an Omega. What Jeong-min wanted was something else. He was going crazy because of the clumsy touching of his member. Every time he tried to touch it, he just swatted the hand away…
“Ha… Kim Ju-hwan…”
What should he do? What on earth should he do…
“Ju-hwan…”
Just as he was about to beg him to please do something, the tongue sucking his chest stopped.
“As I thought, it’s nice.”
“Fuck… what is?”
“The way you call my name, Sunbae. How should I put it? I feel like your voice and my name suit each other well.”
Of all the things he’s had to hear in his life.
“But there’s a reason you’re calling my name. Why, what can I do for you? Hmm?”
The hand that had been gently touching his chest gradually moved downward. Further. Please.
“Ah, right. I have to be gentle today.”
