“It’s probably my pheromones. Hyung, you said you were a recessive Alpha, but you’re quite sensitive, aren't you? Maybe it’s because I’m a dominant Omega.”

Only then did I realize why my heart felt like it was racing when I caught the scent coming from Choi Jeongseo. It wasn't because the scent was good; it was because these were the pheromones of a dominant Omega. I had almost never reacted to an Omega's pheromones before, but clearly, a dominant one was different.

It was my first time being close to a dominant Omega, so this reaction from my body was flustered. If it ended just here, it would be fine, but if I started reacting more strongly to Choi Jeongseo's pheromones, it would definitely become a problem.

Whether he knew my worried thoughts or not, Choi Jeongseo looked at me with a playful expression and asked what his pheromones smelled like.

“What?”

“I’m asking what they’re like, my pheromones. I don’t know how they smell myself.”

“Why are you asking me that?”

“I’m curious how you feel them, Hyung.”

“Sweet.”

“Is that it?”

“Yeah.”

At my simple answer, Choi Jeongseo made a slightly disappointed face.

“Then, how does it feel to sense the pheromones?”

“What do you mean by that?”

“Even if you're a recessive Alpha, you're still an Alpha, Hyung. Unless you're someone who can't feel pheromones at all—but you said you can feel mine right now, didn't you? So how does it feel? Are there any changes?”

“……I don't know.”

“Is it good?”

“I’m… not sure.”

“You’re not sure?”

“Yeah.”

“Hyung, are you sure you’re not actually a Beta?”

Shouldn't he be happier if I said I felt nothing? However, Choi Jeongseo pressed me with an expression and tone that suggested he was dissatisfied with my reaction. It was a strange response.

“Well, I guess if you were a Beta, you wouldn't be able to smell them at all.”

“More importantly…… could you back off a bit?”

I lightly pushed away Choi Jeongseo, who was busy answering his own questions.

“Why? I thought you said you felt nothing?”

At first, it was just my heart beating a little faster. But perhaps because I was continuously exposed to dominant Omega pheromones at such close range, my body gradually began to feel hot. It was a bad sign.

Given the changes in my body, I had no choice but to push him away. If it was like this when he wasn't even in heat, just how intense would it be during a real cycle? The pheromones of a dominant Omega were stimulating beyond comparison to any Omega pheromones I had known before.

“Please.”

I let out a slightly desperate voice toward Choi Jeongseo, who was holding his ground and refusing to be pushed away. Choi Jeongseo looked at my palms pushing against his chest with a peculiar look in his eyes, then burst out laughing.

“All right, all right.”

Choi Jeongseo finally pulled his body back.

“Why are you being so cautious?”

“Because I’m an Alpha.”

“And?”

“Something shouldn't happen.”

“Why not?”

“What do you mean 'why not'?”

“Who’s going to say anything? My mom thinks you're a Beta anyway, and who's going to know whatever happens between us? As long as you and I keep our mouths shut, no one will ever know, right?”

I couldn't tell if Choi Jeongseo was being serious.

“Hey, I know I agreed to just sit around and get paid, but I came here as your tutor, you know? You're taking me too…….”

“Take it back.”

“What?”

“I’m sorry, I take it back. What I just said.”

“You crazy bastard.”

Even after being cursed at, Choi Jeongseo laughed and pounded on the bedsheets as if something was hilarious. I threw the mock exam printouts I had brought at him.

“I told your mother we were going to solve these together today, so do them.”

“Aw, Hyung.”

“I need to have something to show her occasionally, don't I?”

At my sharp words, Choi Jeongseo stopped laughing, glared at me, and turned his gaze to the printouts.

The lesson continued with me practically reciting the answers and explanations to Choi Jeongseo, who stumbled even over the basic problems. It ended a little after the housekeeper’s clock-out time. Of course, it was shorter than the original lesson time.

“If you say something weird like that again, I won't let it slide.”

I stood up, subtly covering my lower half with my bag.

“I got it.”

Choi Jeongseo stood up after me, but fortunately, he didn't seem to notice my strange behavior. It was a relief that his personality was somewhat dim-witted and oblivious.

I slung my bag over my shoulder the moment I turned around. Choi Jeongseo called out a goodbye to my retreating back. Today, I was grateful for that farewell, which lacked even a hint of sincerity.

I escaped Choi Jeongseo's house as if fleeing. I didn't have the courage to take the subway or bus in this state, so as soon as I reached the main road, I held back tears and hailed a taxi.

My body felt strange. Contrary to my hopes that the physical changes would subside while I was tutoring, they didn't improve at all. Perhaps because it was my first time being exposed to a dominant Omega's pheromones, or perhaps because it had been so long since I had reacted to an Omega's pheromones at all, I couldn't control my body as I wished.

It was definitely dangerous. Even now, after leaving that house, the sensation of my solar plexus thrumming whenever I accidentally brushed fingertips with Choi Jeongseo remained vivid. My body, which initially felt like it was running a slight fever, gradually began to change abnormally. I had barely endured the entire lesson, feeling as though I was being tortured next to Choi Jeongseo.

Would it have been better to cancel the tutoring and leave the moment I felt the first change? Regret came too late. Even though I was away from Choi Jeongseo, the heat rising from my lower abdomen spread hotly throughout my entire body.

“I’m going crazy.”

I bit my lower lip and clutched my bag tight. I’d lived perfectly well like a Beta all this time, so why now…….

“Student, we’re here.”

I had been staring at my feet, focusing all my nerves elsewhere, so I didn't even realize the taxi had stopped. I hurriedly paid the driver, who was looking at me strangely, and got out.

After a few fumbled attempts, I finally entered the passcode and stepped inside the house. Jeong Haejun, who said he’d be late today, didn't seem to be home yet, just as he said.

I headed straight for my room. My crotch was fully bulging due to a complete erection.

“Haa…….”

This kind of stimulation was a first. It was the first time I had become erect without even being touched and had it last for an hour without subsiding.

I went into the bathroom and pulled down my pants and underwear at once. My cock, already leaking pre-cum, bounced up and pressed tightly against my lower belly.

I stood leaning against the sink and gripped my cock. I had only stroked it a few times when it twitched and spat out white semen. The thought that I could have ejaculated in the street if I had been just a little later gave me chills.

I took off all my clothes and got into the bathtub. I planned to take a shower and be done with it. A refreshing shower followed by a deep sleep would be perfect. In the end, I hadn't made a mistake at Choi Jeongseo’s house, nor had I created an issue that would become a hot topic outside.

But as life often goes, things didn't go as I planned. Heat gathered in my lower body again. I had been relieved, thinking it would be fine since I had ejaculated once, but as if mocking me, the heat rushed back down.

I finished my shower, trying my best to turn my thoughts elsewhere. The slight erection below was uncomfortable, but I forced myself into fresh underwear and lay down on the bed. My calculation was that if I just ignored it and fell asleep, my body would return to normal by the time I woke up in the morning.

I pulled the blanket up to my chest and closed my eyes. I thought of everything to forget the state of my body. I counted sheep and even recalled the miserable experience of when my parents got divorced. Nevertheless, as if something had gone wrong with my body, the swelling below showed no signs of subsiding naturally.

Thinking I might actually lose my mind at this rate, I couldn't take it anymore and finally sat up. As soon as I thrust my hand into my underwear, my half-erect cock quickly grew in volume, as if it had never ejaculated. I shoved my pants and underwear down to my thighs, where they wouldn't hinder my movement, and shook my cock.

“Haa, ugh.”

Slap, slap.

The obscene sound of skin hitting skin echoed in the room. This time, the climax was slower in coming than before. I was frantically moving my hand, thinking I needed to get it over with quickly, when...

“Hyung? Are you inside?”

I heard Jeong Haejun’s voice, the one who said he’d be home late today. My hand stopped dead.

Knock, knock.

Jeong Haejun knocked on the bedroom door anyway.

“I’m coming in.”

“Wait……!”

I hurriedly pulled up the pants and underwear that had been down at my thighs.

“Why didn't you get back to me when you were home? You didn't even answer your phone…….”

I couldn't pull the blanket up in time, so I just pulled up my knees. It was a rather awkward posture, but this was the only thing I could do right now to keep my situation from being discovered.

“……What were you doing?”

“Wh-what do you mean? I was just about to sleep. You're home early?”

“Yeah, a bit.”

“Then go rest, why are you here?”

“I came by because you didn't contact me and I thought you hadn't come home yet.”

“Ah, I forgot.”

Normally, I might have argued that I didn't see why I had to contact him, but since all I wanted right now was for Jeong Haejun to leave this room quickly, I chose to submissively admit my fault. However, contrary to my wish, Jeong Haejun moved closer to the bed where I was sitting.

“I got a message from Choi Jeongseo today.”

Then he started talking about something out of the blue.

“So?”

The end of my voice trembled slightly. I didn't even want to know whether he had contacted Choi Jeongseo or not. I just wanted him to get the hell out, but the agony of the situation not going my way was intense.

“He said he thinks he made a mistake with you, Hyung.”

“……With me?”

“He told me to tell you his joke went too far. He said he did it because he thought your reaction to his pheromones was funny.”

Only then did I realize why Jeong Haejun had brought up the contact with Choi Jeongseo. It seemed Choi Jeongseo had reported everything that happened during the tutoring session to Jeong Haejun in detail.

“I got an apology for that then and we finished talking about it. It’s fine.”

I pressed my thighs together tightly, trying not to be obvious. If it weren't for Jeong Haejun’s piercing gaze, I would have wanted to pull the blanket that had been pushed to the edge of the bed.

“I’m going to sleep now, so could you leave?”

“Sure, I should leave.”

But the sense of relief I felt when Jeong Haejun nodded obediently lasted only a moment.

“But before that.”

My gaze, which had thought the only thing left was for him to leave, turned back to Jeong Haejun.

“It doesn't look like it's going to go down just by leaving it alone. Do you want me to help?”

“……What?”

“I can see it all, how swollen your cock is.”

My face flushed hot at the direct word. Jeong Haejun, who had come closer, slid onto the bed next to me.

“You were masturbating, weren't you? Without even being able to put your clothes on properly.”

Looking down at the place he touched, my pants were folded and hadn't been pulled all the way up. When I thought about how pathetic I must have looked to Jeong Haejun, pretending to be fine while looking like such a mess, I was so humiliated I wanted to crawl into a hole and hide.

“I guess you really are an Alpha even if you're a recessive one? Did you get turned on smelling Omega pheromones?”

“Why would you say something like that?”

“Am I wrong? You've got it standing up like this.”

Without giving me a chance to cover up, Jeong Haejun’s hand slipped between my legs.

“……Hey!”

“I’ll help you.”

Without my permission, Jeong Haejun wrapped his hot palm around my cock and climbed on top of me. His lips suddenly curved into an arc, like a child who had found a favorite toy.

“Enough, st-stop it!”

I belatedly realized the meaning of the smile Jeong Haejun wore and struggled, but I was no match for the strength pressing down from above.

“What’s this? Hyung, do you really not have any hair here either?”

“Ugh, stop…… ah.”

“I knew you had little body hair, but I thought you'd at least have some here.”

Having my vulnerability, which I wanted to keep hidden from anyone, discovered so absurdly made me feel like I was going to cry.

Jeong Haejun’s hand passed the shaft and moved a little higher. It was a movement as if he were checking to see if there really was no hair. His hand, which had been fumbling at the area where my cock met my lower belly, stroked the shaft again.

“Hyung, you really are completely smooth down there.”

“……Get off.”

“Ah, this is really nice. How is it like this all the way here……”

Jeong Haejun said in a languid voice. I didn't get to hear what he was going to say until the end. I didn't know what he found so nice, but right now he seemed like a crazy person. Seeing as there wasn't a hint of alcohol on him even though he was close, it didn't seem like he had been out drinking, so why…….

“I told you to get off……! Ah, ugh.”

Despite my protests, Jeong Haejun began to move his hand slowly. Unlike when I masturbated, the touch of another person moving in a direction I couldn't predict was definitely more stimulating. Jeong Haejun, who was completely on top of me, moved his hand up and down, controlling the intensity.

While my mind told me I had to stop him somehow, I couldn't actually push him away, only pretending to, because of the instinct that craved this crazy stimulation I was feeling for the first time.

I clenched my fists tight and squeezed my eyes shut. I wanted to believe this whole moment was a dream.

“Ah, please, st- haa, ugh…… nngh.”

“Do you like it when I tighten and release like this?”

“……Hss, ah, ugh.”

The urge to ejaculate, which I had barely felt with my own hand, arrived quickly. My lower belly tightened. I felt like my back would arch without shame, but I held it in, my whole body trembling.

Fruitlessly, the cock throbbing in Jeong Haejun’s palm finally came. The inside of my underwear felt soggy with semen. Only after the ejaculation was finished did Jeong Haejun’s hand slowly pull away, completely covered in white fluid.

“Hyung, you’ll have to change your underwear.”

“…….”

I glared at Jeong Haejun, who spoke nonchalantly as if nothing had happened. But he didn't care about my gaze at all.

“I’m really leaving now. Good night.”

Without even wiping his hand covered in my semen, Jeong Haejun left the room just like that. At the sound of the door closing, the tension left my entire body.

I sat there dazed for a moment, unable to easily accept what had happened to me. It was only when I recalled the sensation of Jeong Haejun’s hand stroking the shaft and the crazy, blooming pleasure that I clutched the blanket and screamed inwardly. What the hell did I just do……!

I couldn't understand Jeong Haejun for doing such a thing so casually, but I couldn't understand myself either for not resisting more and losing my senses in his hands.

I bit the blanket for no reason. I felt like if I didn't do something like this, I would scream loud enough for Jeong Haejun, who would have returned to his own room, to hear. It was a night when I felt like I would go crazy from the shame enveloping my entire body.

The next morning, as soon as I opened my door and stepped out, I ran into Jeong Haejun, who looked perfectly fine. I had tossed and turned all night from the shame of having received a handjob from a guy I barely knew, but Jeong Haejun seemed to have slept quite well.

“Why does your face look like that?”

It was a look and a question as if last night's memory had been cleanly cut out. There was no need for me to dig it up when Jeong Haejun was pretending not to know. Thinking I should find another part-time job and figure out a way to move out of this house quickly, I rubbed my face. Then, pretending not to care about last night, I asked back what was wrong with my face.

“Does it look like I didn't sleep well?”

“Well, I guess so.”

“Aren't you talking about yourself too much like it's someone else's business?”

In response to Jeong Haejun’s chiding, I only gave a shrug. Honestly, I didn't want to talk much with him right now. Looking at his face, I felt like the memory of last night would resurface and heat would rush to my face at any moment.

Last night's event wasn't the kind of memory that could be easily shaken off. Moreover, strictly speaking, it had happened only a few hours ago. I was at a point where I found it amazing that Jeong Haejun could strike up a conversation with me with his usual face even after doing such a thing.

Even though I had come out after doing my own mind control in my room, I felt a strange twitching near my mouth. So, I tried my best to act even more nonchalant. If I showed that the aftermath hadn't faded yet, Jeong Haejun would realize I was bothered by last night, and if even he became conscious of last night because of me, I really wouldn't be able to face him for even a second.

“Well, that aside. What about the vein registration? You haven't done it yet, right?”

However, unlike me, Jeong Haejun didn't seem to have any intention of ending the conversation easily. Fortunately, he turned the subject to something else, and I felt the blood that had been rushing to my face earlier cool down slightly.

“……Yeah, I didn't have time.”

“Do you have morning classes today?”

“No.”

“Then go and get it done.”

“Don't you think the management office isn't open yet?”

I had the keycard anyway, so there wasn't much inconvenience in my daily life, and thus I hadn't felt the need to get the vein registration done. Also, I didn't know when I might be leaving this house.
