“Hnnngh.”

The moans that had been wavering between pain and pleasure changed in an instant. Her opening, having adapted to the massive p*nis, squirmed to accept even more. Before she knew it, Hyena was pushing her chest out further to make it easier for Gunwoo to lick.

Like he was responding, he swallowed her n*pple in one mouthful. 

The hot, wet mouth wrapping around her without gaps, the tongue tip stimulating her n*pple, and even the p*nis constantly burrowing into her opening—all these sensations she’d never felt before in her life converged in one place.

“Haaah. This is strange.”

The lips that had been holding her n*pple pulled away. His dark red pupils, perfectly colored with desire, captured Hyena writhing from the pleasure he was giving her.

“You can be as strange as you want.”

Gunwoo whispered while rotating his hips heavily. At the sensation different from when he thrust in quickly, her hand gripping Gunwoo’s shoulder naturally tensed. She couldn’t hold back the pleasure spreading from below anymore.

“Hngh. Op, pa.”

“Come, on my c*ck.”

His low voice gave final permission. The pleasure that had been building and building burst at those words.

“Haaaaah. Ngh. Hngh.”

Hyena reached climax just like that. His p*nis thrust into her opening as it rapidly opened and closed.

Faster and deeper than anything before.

Pleasure piled on top of pleasure. Hyena sobbed at the feeling that something would pour out below.

“Hng. No more… hngh.”

Unable to overcome the extreme pleasure, her opening finally poured out fluid. Gunwoo, who’d been pressing down the female body that kept bouncing up while endlessly thrusting his hips, soon let out a single moan.

“Ngh. Hyena.”

Warmth spread inside her body. The movements that seemed like they’d never end stopped like a lie. Rough breathing filled the bedroom. 

With her face buried in Gunwoo’s shoulder, Hyena gasped for breath. Her body and mind, which had been floundering in pleasure, slowly began to return.

“Now stop…”

Pull out.

The last words weren’t completed. The p*nis still remaining in her opening had swelled in an instant.

“Why again…”

“The night is long.”

Gunwoo added while languidly rotating his hips.

“Try taking it all in.”

***

At the uncomfortable feeling pressing on her lower back, Hyena’s eyes fluttered open. Soon an unfamiliar scene entered her view.

A feeling quite different from her own disheveled room.

‘Do Gunwoo’s room.’

The moment she recognized that fact, last night’s events flashed through her mind. Gunwoo endlessly burrowing into her, and herself moaning until her voice went hoarse beneath him, on top of him.

She couldn’t even count how many times she’d reached climax.

She wished she couldn’t remember, but a sigh naturally flowed out at yesterday’s situation that vividly came to mind.

‘I had s*x. With Do Gunwoo.’

At the inescapable reality, Hyena squeezed her eyes shut.

They’d spent their whole lives as oppa and dongsaeng, but one night’s mistake had brought their relationship to the brink of breaking. It was all her own doing. She’d finally failed to hold back and burst out the feelings she’d been forcing down all this time.

‘Maybe oppa doesn’t remember what happened yesterday? He was really drunk.’

She pinned her hopes on the slim possibility. She felt like she couldn’t bear it otherwise.

‘First, I need to get out of here.’

Following reason’s warning, she struggled to remove the arm binding her. Her lower body, tormented all night, cried out in pain, but she had no time to worry about such trivial things.

Just as she was about to escape the bed, a firm arm bound her again.

“Where are you going?”

A voice drunk with sleep asked.

“To, to my room.”

“Sleep more. You barely slept.”

Gunwoo added while pressing his lips to her bare shoulder.

“Or should we do something else?”

From Gunwoo’s words, she could tell for certain. He vividly remembered what happened yesterday too.

There was no helping it now.

‘The sooner you draw the line with things like this, the better.’

Having made up her mind, Hyena opened her mouth.

“What happened yesterday was a mistake, so let’s pretend it didn’t…”

“A mistake?”

“You were really drunk and…”

A hard voice cut her off.

“You weren’t.”

“I also got swept up in the mood…”

“Take responsibility.”

The words overlaying her voice were completely unexpected. Hyena’s eyes widened.

“What?”

Suddenly her body turned. Soon she faced his darkly colored pupils.

“Take responsibility.”

There was no trace of playfulness on Gunwoo’s face.

“Why? Can’t take responsibility?”

“What responsibility exactly…”

“You f*cked me while I was drunk.”

“…”

“Can’t do it? Then just follow me. I’ll take responsibility.”

The conversation was going in circles.

“There’s no need to go that far.”

“It was your first time.”

“Oppa…”

“It was my first time too.”

Hyena’s eyes widened at the unexpected words.

“That’s impossible.”

The unfiltered words leaked out of her mouth.

It was his first time, yet he was that good?

Last night had been another world entirely for her. Of course, her body opening for the first time was painful. But what she experienced after that—her vision flashing and her whole body devoured by pleasure…

Hyena’s face flushed red as she recalled last night. She suddenly felt a gaze.

“Can you even have s*x without looking at this?”

At Gunwoo’s words, her gaze automatically went downward. His p*nis, having gotten er*ect at some point, was twitching.

“I told you—you were the first to see my c*ck. So naturally it had to be my first time.”

Confusion filled Hyena’s face.

“Have you ever seen me lie to you?”

“…”

“We took each other’s first time.”

A strange emotion, neither happy nor unhappy, moistened her heart. Hyena had s*x with Gunwoo because she had feelings for him. Because he was her ‘first love’ that she’d longed for so much.

But Gunwoo was trying to take responsibility for just one reason—that they’d shared their first time. She hated that.

“This isn’t the Joseon era—there’s no need to take responsibility just because we shared our first time.”

The moment she finished speaking, she saw the corners of his mouth slowly rising. Unable to meet Gunwoo’s eyes, she fixed her gaze on his particularly red lips.

“Quite a liberal way of thinking. Makes me wonder if you’re really the Yoon Hyena I knew…”

“People change.”

“Fine.”

A simple answer came back. It seemed the awkward situation was about to wrap up.

It was clearly the ending she wanted, yet strangely she felt like a hole had been punched in one side of her heart. Hyena forced the corners of her mouth up.

“Good thinking. Let’s pretend yesterday didn’t happen and…”

“We can’t pretend something that happened didn’t happen.”

Gunwoo, who’d spoken firmly, slowly closed the distance between them. His gaze fixed on the sheet clutched at her chest, he whispered.

“If you can refuse what I’m about to do…”

Hot breath poured out at the distance so close that some body part would touch at any moment. Hyena involuntarily flinched.

That’s when Gunwoo’s hand overlapped hers gripping the sheet.

“I’ll think about it.”

Before she could understand his words, the sheet covering her chest fell away. It happened in an instant.

“I’ll consider it.”

The last words poured entirely onto her chest. Her n*pples, sensitized from last night’s aftermath, stood er*ect.

“What are you doing…”

Before the words could end, Gunwoo’s lips descended onto her chest, which had turned mottled from being sucked and bitten all night. Soon his moist tongue tip touched her n*pple.

‘I can’t.’

Her last remaining reason rang an alarm in her head. Hyena reached out her hand. Or tried to.

But she couldn’t move. Quick Gunwoo was pressing both her hands so she couldn’t budge.

“You were always in my dreams.”

“…”

“From when I started having wet dreams.”

Gunwoo’s voice was wetly soaked. She couldn’t understand what he was saying. Before she could interpret the thought that arose in her mind, Gunwoo whispered.

“You were always there when I gripped and shook my c*ck.”

His blunt p*nis touched her lewdly moistened lower parts. At that flesh-trembling sensation, Hyena involuntarily let out a moan.

“Aaah.”

Capturing her appearance completely in his eyes, Gunwoo whispered.

“You made me like this.”

As soon as the words fell, his p*nis entered inside. At the startling feeling of the thick tip entering, Hyena silently opened and closed her mouth.

An animalistic glint descended on Gunwoo’s face, which had been feigning indifference all along.

“So you have to take responsibility. Right?”

Thud—at the p*nis that thrust in to the end with a sound, Hyena couldn’t even answer and only let out a death moan.

“Hnnnngh.”

Right at that moment, Gunwoo’s voice flowed into her ear.

“Yoon Hyena.”

“…”

“You were mine from the beginning.”

Terrible possessiveness. Her lower parts, struggling to swallow his p*nis, convulsed.

“Just like I’m yours.”

Hearing the voice flowing into her ear, Hyena reached org*sm just like that. Languidly pressing down the female body that intermittently bounced up, Gunwoo whispered once more.

“So don’t think about running away half-heartedly.”

***

Standing in front of the heavy iron door, Hyena pressed the door lock password with trembling hands. The door opened with a clear sound.

Gunwoo sat in the small room full of empty liquor bottles. His body, usually without a hint of dishevelment, swayed here and there—how much had he drunk?

“Oppa.”

At Hyena’s call, Gunwoo raised his gaze. Only then did his pupils, soaked in alcohol, focus.

“Huh? Hyena?”

“Yeah. It’s me. I came because I couldn’t reach you.”

“Ah, contact…”

Gunwoo’s gaze touched the phone with its shattered screen lying far away.

“As you can see, it’s in that state.”

Puhaha—Gunwoo, who’d let out a powerless laugh, picked up his drink again.

“Didn’t you see the message I sent?”

“Message?”

There was no trace of lies on Gunwoo’s face as he asked.

She’d gathered courage to send that she liked him. Disappointment colored Hyena’s face.

Suddenly Gunwoo reached out his hand. Just as it was about to touch her cheek, the hand withdrew.

“Ha, f*ck.”

Gunwoo, who’d spat out a vicious curse, roughly swept his face.

“Even in a moment like this, only shitty thoughts…”

Incomprehensible words kept pouring out. She couldn’t just listen anymore.

“What thoughts?”

At Hyena’s question, his unfocused pupils reached her.

“If you knew, would you let me have it?”

“If it’s something I can do, anything…”

Gunwoo stared at her intently.

“What if I take advantage of those words to do something terrible?”

“Oppa wouldn’t do that.”

“Are you sure?”

“…”

“I’m a son of a b*tch.”

Whenever Gunwoo occasionally put himself down like this, her chest felt stuffy. Not even knowing my feelings.

“I could do something terrible to you right here, right now.”

Gunwoo’s pupils as he said this were reddishly heated.

“Do it. If it’s oppa doing it…”

Before the words could end, Gunwoo came right up close. Her breath caught at the masculine scent that suddenly wafted over. Suddenly Gunwoo lowered his face. At the distance so close their lips would touch, Hyena squeezed her eyes shut.

The breath pouring over her lips, her lips parched from that breath—it didn’t feel real.

But nothing happened.

“When you can’t handle it.”

Gunwoo, who’d bypassed her lips, whispered in her ear. The breath wetly pouring into her eardrum reminded her of reality.

“No. I was just so surprised…”

“All guys’ heads are dirty. So never show an opening.”

Even knowing he was saying it out of concern for her, it felt bitter because it seemed like he kept pushing her away.

Their relationship had changed drastically after entering university. The two, for whom being attached every day had been routine, slowly began to drift apart.

‘Because I’m busy. Because I have work. Can’t be helped.’

Like that, a week became a month, became two months, and later it reached the point where seeing each other was stranger. The only reason they could maintain even this level of relationship was thanks to her efforts.

“That’s too much. How much I…”

Before the words could end, Gunwoo cut her off.

“Hyena.”

At the affectionate call, she raised her gaze.

“When I’m with you, I confirm every moment that I’m a son of a b*tch. I feel keenly that dirty blood can’t be changed.”

If only I could let you go.

The whisper added like a soliloquy hurt her heart. She’d been in the closest place yet hadn’t noticed at all that Gunwoo was thinking such things.

“No. Oppa is absolutely not that kind of person.”

Hyena shouted, but it didn’t reach Gunwoo.

“If I could, I’d want to drain all that b*stard’s blood existing inside me. I want to eliminate the dirty blood flowing in me with my own hands, but I can’t.”

Gunwoo laughed painfully. Tears pooled in Hyena’s eyes. Wiping away the tears rolling down her cheeks with his fingertips, Gunwoo whispered.

“So, Hyena.”

She wanted to cover her ears. But she couldn’t because of Gunwoo meeting her gaze squarely.

“Just as you are now…”

As a younger sister, not a woman.

The meaning in his words was conveyed completely. The relationship she’d thought was ‘special’ stabbed her like a dagger.

“Stay by my side. Forever, unchanging.”

***

Her eyes snapped open. Only then did Hyena realize she’d been dreaming.

Sometimes old events appeared in her dreams like this.

‘Stay by my side just as you are now. Forever, unchanging.’

The ‘first love’ that had ended without even a confession at those words still hurt her. Click—the door opened. Her ‘first love,’ with whom she’d only shared bodies last night, was approaching her.

‘What should we call our relationship now?’

‘F*ck buddies?’

The word she rolled around in her mouth wasn’t entirely bad. Maybe this was also progress in their relationship. Hyena forced herself to be self-deprecating.

“Can you get up?”

When had he been pushing her like a beast—now asking gently was clearly a foul.

Instead of answering, Hyena raised her body. A moan naturally flowed out at the dull pain covering her whole body. A tray was placed in front of her.

Fragrant porridge and side dishes were neatly arranged. Seeing the food made her hungry.

It was natural since she hadn’t eaten all day. Just as Hyena picked up her spoon, she let out the thought that arose in her mind.

“I think it’s better to keep this a secret.”

“Keep what?”

“This… relationship.”

“Ah…”

The drawn-out ending conveyed Gunwoo’s uncomfortable mood. Hyena pretended not to notice and scooped porridge into her mouth.

“From who?”

“From anyone.”

“So you want to keep it as just our secret?”

She nodded at the simple summary. Avoiding Gunwoo’s gaze staring at her, Hyena opened her mouth.

“If something goes wrong, we might never see each other again for the rest of our lives.”

It was the decisive reason Hyena couldn’t properly confess to Gunwoo.

“I don’t think I could do that—can you, oppa?”

“So you want a relationship you can return to normal even if things go wrong?”

“…”

“Like f*ck buddies?”

Hyena mechanically scooped porridge while spitting out the words she’d heard in her dream earlier.

“I want oppa to just stay by my side as you are. Forever, unchanging.”

Even while speaking, she couldn’t raise her face.

Because she freshly felt the pain of when she’d heard those words from Gunwoo.

“If that’s what you want, I’ll have to do that.”

Gunwoo, who’d already moved the empty tray to the bedside table, climbed onto the bed. A hand entered under the sheet. Though just a finger grazed her, the touched part was colored with pleasure.

“Since I don’t have a choice.”

The last whisper disappeared into her mouth. Hyena was once again colored by the pleasure Gunwoo gave.

The seemingly endless Sunday night was flowing by like that.
