“Ouch!”
As the tip pushed in, a searing pressure clamped down hard, making it nearly impossible to breathe. The pain was brutal—so sharp it felt like I was being ripped apart. I reached out to push him away, but Kang Biso only held me tighter, gently consoling me even as he kept moving.
“Are you okay…?”
“Ugh…”
Would you be okay in my place?
Kang Biso kissed me again, slipping his tongue between my parted lips, the wet sound echoing in the room. My waist trembled, still trying to adjust to him, every muscle clenched tight.
“Haah… you’re so tight…”
Sweat dotted Kang Biso’s brow, his face twisted in effort. He stopped pushing in and instead began to slowly pull back out, murmuring low under his breath.
I gasped for air. Even that movement—just pulling out—was nothing like a finger. It felt like I was going to break apart.
My insides were being dragged along so vividly, I squeezed my eyes shut. Was he done? Was he pulling out? Almost fully out now… a sliver of hope bloomed inside me, and I unconsciously let my guard down. That’s when—
Thud!
As if he’d been waiting for that moment, Kang Biso slammed back in all the way.
“Ah!”
His thick cock plunged deep, and the sudden shock twisted my waist in pain.
It honestly felt like my body was splitting open. Was sex supposed to hurt this much?
As I writhed under the onslaught, Kang Biso whispered in a voice rough with thrill.
“Finally… it’s all in.”
He sounded so satisfied. I should’ve said something back—but I couldn’t focus. Even after all the training I’d gone through as a Special Agent, after all the injuries I’d endured, I’d never felt pain like this.
Thankfully, Kang Biso didn’t move recklessly. He waited, letting me adjust, brushing soft kisses along the side of my neck. As my breathing slowly steadied, he asked again—this time, his voice barely restrained.
“…Can I move?”
I wanted to say no. The pain was still sharp, still clinging to my nerves. But the look in his eyes—filled with restraint and desperate yearning—kept the refusal stuck in my throat.
I hesitated, then gave him a small nod. Kang Biso started to move, slowly rolling his hips.
“Haah…”
“Ah, ugh…”
I could feel everything. The drag, the slide, the way he filled me—it was all too much. The pain lingered, but a strange new sensation had begun to stir beneath it. Something faint, something maddening. Kang Biso kept searching deeper, like he was looking for something.
“It should be around here…”
Then it happened.
“Hah!”
My vision exploded in white.
Kang Biso paused, watching me carefully. Then he grinned, licking his lips. And the next moment, he slammed his hips forward, rough and eager.
“Eek! Haah!”
A pleasure I never thought possible tore through me, wild and overwhelming. It felt like electricity was dancing along every nerve, lighting me up from the inside. My moans grew louder as Kang Biso found that spot again—and again.
Wet sounds echoed in the room, obscene and clear, and his thrusts picked up speed.
“Eek, heek, ah…”
The more desperately he moved, the louder the slap of our bodies became. I couldn’t take it. I grabbed onto his forearm, clinging tightly, feeling like I might fall apart.
I’d never come so fast in my life. My entire body trembled with release.
“Haah… haah…”
That was the second time already. I thought it’d be enough. I tried to subtly pull away, to hint that I needed a break—but Kang Biso didn’t let me go.
“Ah!”
He yanked me back in and thrust deep, making me cry out. The climax hadn’t even faded yet, and the pleasure that hit next felt unreal. My cock, which had gone soft just moments ago, sprang back up with a jolt.
“Ahk.”
This is insane. I can’t handle this.
“Hyung…”
“Biso-ssi… heek!”
I begged, my voice cracking with every moan. But Kang Biso didn’t stop. He only leaned in closer, whispering sweet nothings against my ear. His eyes were clouded with desire—like a beast drunk on its prey—full of warmth, satisfaction, and unending hunger.
“I love you… I love you, Hyung.”
“Haah.”
With that look in his eyes, he started moving his hips again. I thought I was too drained to make a sound, but the pleasure hit so hard that moans burst from my mouth without warning.
“Ah—nngh! Ugh!”
“I love you. I really do… Hngh.”
In that moment, Kang Biso wrapped his arms around me like he was trying to crush me, his whole body trembling. I felt him release deep inside me, a hot rush flooding into me all at once.
“Hyung… seriously… it felt so damn good.”
“…”
I wanted to hug him back and say I felt the same, but I didn’t even have the strength to lift a finger.
My eyelids grew unbearably heavy, and before I knew it, I blacked out—like someone had just flipped a switch.

“Mmm…”
When I opened my eyes, the first thing I saw was Kang Biso’s face. Why the hell am I in bed with him? My brow furrowed as last night’s events started trickling back.
Our first night doing anything remotely adult… and I’d practically passed out. The flashes I could recall were just Kang Biso relentlessly driving himself into me.
“Haah… what kind of stamina even is that…”
I hadn’t moved, but my ass was already aching, and my legs felt like lead. Meanwhile, Kang Biso—probably thanks to his S-Rank stamina—looked completely satisfied, his face the very picture of post-coital bliss.
I need to get to work…
Could I even make it to the Guide Center like this?
I turned my head toward the window. Judging by how high the sun was, I was already way past late.
Looked like I’d need to call in sick. Even if it was late, I should at least contact the Team Leader. But Kang Biso had me locked in his arms, and I couldn’t budge. He seemed to be fast asleep, and I didn’t really want to wake him—but I didn’t have much of a choice.
Just as I turned to nudge him awake, our eyes met.
“Did you sleep well?”
I scowled. Not a trace of sleepiness in his eyes—just pure affection as he gazed at me like I was the most adorable thing in the world.
“…When did you wake up?”
“I never slept. How could I, with you lying right next to me?”
As he spoke, he subtly pressed his lower half against me. I flinched, quickly pulling back. Thankfully, it seemed he wasn’t planning on taking things further—he just laughed playfully and relaxed the arms wrapped around me.
A hint of disappointment flickered in his eyes, but I ignored it. After everything that happened last night, what more did he want? I turned away and bundled myself tightly in the blanket before carefully getting out of bed.
“Ugh…”
The moment I sat up, pain shot through my lower back so sharply that my face twisted, and a groan slipped out.
“Are you okay? Just lie back down—don’t push yourself.”
Startled, Kang Biso shot up and helped ease me into his arms so I wouldn’t collapse.
I bit down hard on my lip. It hurt like hell. Even lying down had been painful, but sitting up made me realize just how wrecked I really was. Moving felt impossible.
I let out a long sigh.
“Kang Biso.”
“Yes, hyung?”
“Could you grab my phone? It’s in my pants pocket. I need to call the Center.”
Kang Biso moved quickly and handed it over. A glance at the screen showed several missed calls—and it was already well past lunchtime.
I called the Team Leader and requested a sick day. Luckily, all the moaning I did last night had trashed my voice, so when I said I wasn’t feeling well, he believed me instantly.
“Haah…”
I hung up and flopped back onto the bed in relief. Kang Biso quietly laid down next to me again.
“…So you’re off today?”
“Yeah. Ended up that way somehow.”
“We spent all night together yesterday, and now today too… I’m seriously so happy.”
Kang Biso beamed like he had the whole world in his hands. It wasn’t the sultry smirk from last night—this was a pure, heartfelt smile. And somehow, it made my lips curl up just a little.
He slipped an arm under my head like a pillow and kissed my cheek with a soft mwah. Just a light peck, but with all the memories of last night still raw, my face grew a bit warm. Kang Biso hugged me tighter, then whispered near my ear.
“You must be tired, right? Just sleep a little more.”
“…And what are you going to do?”
“Watch you sleep, of course.”
His lazy tone made my body relax even more. Guess I really had overdone it yesterday. The fact that I was even getting sleepy again now said enough. My eyes started blinking slowly, and I rubbed at them groggily.
After a round of kisses, his hand stroked gently through my hair. Comforted by the soft touch, my eyes fluttered shut again.
***
It was already late at night by the time we stepped out of the motel.
Kang Biso wrapped an arm around me, supporting my limp body as I stumbled along beside him. Normally, I would’ve brushed him off without a second thought, but tonight… I just didn’t have it in me. Without a word, I leaned into him and let him guide me toward the Guide Dormitory.
“Do we really have to go back to the dorm? If we went to the hideout instead, I could take care of you properly…”
“…Yeah, I need to. I didn’t go back last night, and… I have work tomorrow.”
Honestly, if I stayed with him any longer, there was a good chance I’d end up missing work again. After what happened today, I couldn’t let that happen twice in a row.
I knew Kang Biso meant well, but after being dragged through the wringer all night long, my faith in his sense of “restraint” had definitely taken a hit.
“We’re here.”
We eventually made it to the front of the dormitory. Kang Biso didn’t let go of my hand—if anything, he gripped it even tighter, like he didn’t want to say goodbye. I felt a little tug of reluctance too, but unlike him, what I really needed right now was rest. I gently started to pull my hand away.
But instead of letting go, he wrapped his arms around me and pulled me into a hug. He buried his face against my shoulder and rubbed his cheek against it like some needy kid begging for affection. I got the message loud and clear. I sighed and gave him a few soft pats on the back.
Finally, Kang Biso let out a quiet sigh and slowly stepped away.
“I don’t want to leave, but… we’ll see each other tomorrow, right?”
“Yeah. I’ll see you tomorrow.”
We exchanged a short goodbye and turned to part ways. But I could feel his gaze still glued to my back, hot and lingering. I turned to look, and sure enough—he was standing there, staring at me with a look so full of longing it made my heart twist.
Damn it. I shouldn’t have looked back.
That expression of his made it impossible to keep walking. Why the hell did he look like a puppy that just got abandoned?
In the end, I stopped and beckoned him over with a wave of my hand. His eyes widened in surprise, and he rushed toward me without a second thought. As soon as he reached me, I placed both hands on his cheeks and gave them a good tug, stretching his face into something truly ridiculous.
“Hyuuung? Whaw awe you doin’?”
“…Quit making that face. We’re seeing each other tomorrow, so don’t pout like I’m leaving forever. Go home already.”
“Yesh, hyung.”
Even with his face all scrunched up, he smiled with that dopey, half-moon look in his eyes and nodded. I gently ruffled his hair, and finally—finally—I was able to head inside, feeling just a little bit more at peace.
“Haa…”
The second I stepped into my room, I collapsed face-first onto the bed. My entire body ached. Not a single spot wasn’t sore.
Still… lying down helps a little.
I stared blankly at the ceiling, letting my mind drift—and before I knew it, memories of last night came rushing back.
When I was with Kang Biso, I’d been too overwhelmed, too out of it, too sore to really think. I just… went along with everything. But now that I was alone? It all hit me at once. Everything was still so fresh—vivid, like it had just happened.
I hadn’t realized it at the time, but thinking about it now, I wanted to bury myself in a hole. I was mortified.
Groaning, I yanked the blanket over my head and screamed internally.
How the hell am I supposed to face Kang Biso tomorrow?
In the end, crushed by the weight of shame and secondhand embarrassment, I spent the entire night wide awake.
A passionate night
