The man asked with a strained, low voice. His eyes were flushed red, as if he were barely holding onto the thread of his reason. I pressed my lips against the corner of his eyes and licked them. The man’s sweat and my tears mixed, tasting salty.
With me sitting on his thighs, the man lifted his hips. The penis that had been caught at the entrance pushed inside. Holding onto me as I stiffened like someone being electrocuted, the man pulled me down and repeatedly thrust his hips upward.
My limbs shook from the impact, like a frog pinned to a skewer. My gaping lips couldn’t even let out a moan; the man roughly swallowed and sucked the lips from which only a metallic rasp escaped.
My groin began to ache with a tingling sensation. My buttocks were crushed, and the hot club repeatedly gouged my insides. Despite the overwhelming feeling, I awkwardly shifted my hips, trying to follow the man’s movements. Every time I did, a low moan escaped the man’s lips.
The arms I had wrapped tightly around the man’s shoulders slipped with sweat. Digging my fingertips into his broad shoulders, I clung to him. Heat was gathering in my rubbing groin.
The man laid my body, which kept tipping backward, onto the bed and lowered himself over me. Caught between the bed and the man’s massive body, I twisted my waist helplessly.
My body jolted from the force pushing up from below, and my body, held in the man’s arms, trembled intermittently as if having a seizure.
As if this act were the last of my life, I clung to the man desperately. I craved the man’s lips, his touch, his embrace, and his penis.
My vision was blurred, my sense of smell felt paralyzed by the thick sweetness, and the pleasure that made my whole body tingle was similar to pain.
The man’s moans, echoing through hot breaths, sounded like the cries of a predator enduring pain. I grabbed the man’s face, kissed him, and tangled our tongues.
The penis moving in and out of the hole was gradually increasing in volume. I could tell by the tight sensation, and that pressure seemed to be felt by both me and the man, as similar moans burst out.
I clung to the man like a child who didn’t know what to do, and the man, spreading my thighs and pressing down to dig even deeper, repeated the insertion so strongly it felt as if he would crush my lower body.
The sound of slapping echoed as his testicles hit my buttocks hard enough to be painful. The fluid-soaked testicles made a squelching sound, sticking thickly to my buttocks and pulling away, and I twitched my hips at the faint pain and pleasure.
“Come, come inside me.”
I instinctively knew we were reaching the end. I wrapped my strengthless legs around the man’s waist, pleading, and used my hand to shake my own penis, which was leaking sticky fluid.
“Not yet, just a little more…”
The man spoke with difficulty, nibbling on my earlobe. The tip of the hard penis poked and rubbed the inner wall, and unable to withstand the stimulation, I poured out a thin liquid from the penis I was rubbing with my hand.
“Haa, ngh… ah…”
As I ejaculated, contracting every muscle in my body, the man stopped moving with his penis still buried inside.
As I breathed slowly, pouring out semen, I could feel the man’s penis inside my belly. I slowly tightened and released it, then tightened it again, lifting my tear-filled eyes to look up at the man.
“I need it. I want… you to come inside me.”
Ejaculating on my own didn’t quench the thirst. I wanted him to stir my insides and pour out hot seed to fill me up. My instinct told me that only by having that would this thirst be quenched.
I ran my hand over the man’s neck, which had become stiff with tension. I wanted to bury my lips against the skin slippery with sweat. I had to quench my thirst with the man’s sweat and cool the heat with the man’s seed.
I lifted my limp arms and pulled the man’s body toward me. The man, who had stopped for a moment, began to move again like an excited beast.

I had significantly more reason left than on the first day. The speed of calming down was faster, and although the boiling heat inside hadn’t disappeared, it remained as a dull glow and wasn’t painfully distressing.
After the man’s first ejaculation, we regained a bit of composure; though we were still connected below, we were in a state where we could at least share a bit of conversation.
“I’m tired.”
My voice was completely hoarse, sounding terrible. As I spoke with a lingering cough, sounding almost like I was whining, the man clicked his tongue.
“This is why I asked why you didn’t take the medicine. I told them to bring it to you; did it not arrive?”
“I was asleep, so I don’t know if it came or not. I was just sleeping, but then the pain came back… and when I opened my eyes, you were right there.”
“I did tell you to stay over, but I didn’t think you’d actually glue yourself to this place. Is there something else you want?”
The man narrowed his eyes and looked down at me. His gaze was filled with suspicion, but since his lower half was still moving, it was just laughable.
“Don’t make me laugh. All I want from you is a good fucking. I think you’re pretty much the same, anyway.”
If he wanted to deny it, he’d have to calm his hips down first. As if to prove a point, I tightened my hole firmly, and the man’s neck instantly flushed red.
“I guess you’re feeling a bit more like yourself now?”
The man asked in a threatening tone, pushing his member in deep. Wanting to savor this leisure for a bit longer, I hurriedly shook my head.
“I didn’t know a heat cycle was this hard. Omegas deserve a reward. How do they go through this every month?”
“If you knew that, you should have taken the medicine. I don’t know if you’re stubborn or just stupid, enduring it like that and falling asleep.”
I knew I was stubborn and stupid myself, but hearing it from someone else’s mouth hit differently. He certainly has a way with words. I considered tightening down again, but since that method had a high chance of rebounding on me, I lightly tugged on the man’s hair instead.
“I didn’t know yesterday. I was completely out of my mind, and it was only this morning that I finally came back to my senses. After it was all over, I just had this feeling of, ‘I don’t know what it was, but that was hard.’ But now, while we’re doing it, I feel like I’m going to die because it’s so taxing. Yet, I feel like I have to do it, and when I do, it feels good, but it’s still exhausting. It’s an infinite loop.”
My muscles had relaxed to the point where I was just clinging to his member, but because the condition of my inner walls was so good, they were sucking and churning wildly. Only today did I realize that my lower body could move independently of my will.
“Is it evening already? Father is really going to scold me.”
“It looks like going home today is out of the question. I don’t know what kind of household raises an Omega and lets them run loose like this. Unless you’re a cast-off child, any normal family would be in an uproar.”
“My family isn’t exactly normal, but it would probably be an uproar regardless. Or maybe he’s working hard to hide it.”
The latter felt more likely. To avoid being criticized by my eldest and second brothers, Father might be struggling to maintain a nonchalant expression. Since Father, the hospital director, doesn’t seem particularly interested in me, there’s a high chance he doesn’t even know if I’m home or not.
But why is the hospital director, Father, not interested in Cha Soo-kyung? The eldest and second brothers might hate him because he’s a half-brother, but to Father, Cha Soo-kyung is his child. If he married Father despite the opposition of Grandfather, the chairman, there’s no reason to treat him coldly just for being Father’s child.
“You’re thinking about something else. You really must be feeling better.”
The man, noticing my distraction like a hawk, pulled one of my legs up and drove deep into the opened gap. I gasped sharply, nearly biting my tongue, and glared at him.
“Why that face? I’m the one being tossed around by your heat. I’m the victim here.”
If he framed it that way, I had nothing to say, but I still felt wronged. I didn’t want to enter an Omega’s body, and I didn’t want to experience something like a heat cycle. I didn’t particularly want to mix bodies with another man, nor did I want to be aroused and erect against my will.
This really… doesn’t feel like my body. An anxiety began to grow—that it would become harder and harder to sustain myself with my own will, that I would slip away from my consciousness and return to being Cha Soo-kyung, or that I might disappear entirely.
“Shh, don’t cry. I won’t be rough.”
I don’t know what my expression looked like, but the man whispered as if soothing me and softly sucked on my lips. As if to prove his words, the movement of the member sliding out and back in was careful and tender.
“I’m… hungry.”
The voice I let out while holding back tears sounded a bit nasal. As I rubbed my cheek against the man’s shoulder, he let out a hollow laugh.
“At this timing? You really are something else.”
“I can’t help it. In twenty-four hours, all I’ve had are a few sips of water you gave me this morning, but my body is hitting peak exercise levels. Are there no Omegas who starve to death during their heat?”
There must be Omegas who spend their heat with an Alpha without taking suppressants; I don’t know how they manage to keep this up for several days. Do they wash, eat, and handle their chores when the pheromone madness subsides for a moment? Did I miss that timing and end up starving?
“No, there aren’t.”
“Then I’ll be the first.”
At my whining, the man finally burst into laughter. Because he laughed from his chest, the member buried inside me vibrated along with it, making my inner walls tremble.
“Don’t laugh. It feels weird down there.”
As I scolded him, pressing my palm against his lips, the man licked my palm as if tickling it with his tongue.
“Once I cum this time, let’s eat and wash up after that.”
“What if I want to do it again?”
“I’ll ask them to bring suppressants too.”
“Then will it get better?”
“The medicine won’t work instantly, but it’ll gradually get better. You can go home then. Until then, I’ll stay with you.”
“So hang in there,” the man said playfully. Looking up into the eyes of the smiling man, I hugged his broad shoulders.
“Are you always this kind? Or are you only this nice to the people you have sex with?”
