“This Friday. That’s when we’re going to retrieve the Book of Wishes.”
Kang Biso, who’d come home late that night, spoke with a grave expression.
“…Two days from now?”
“Yeah. We’re going to sneak in and steal it.”
Two days. That was sooner than I’d expected. The sudden urgency caught me off guard, but experience from my years as a Special Agent told me this kind of decision wasn’t unusual. Moving quickly while all eyes were still on you often worked to your advantage.
Still, just because I understood didn’t mean I wasn’t worried. Infiltrating a government facility to steal something that important was no small risk—and Kang Biso was the one going in.
My anxiety pushed me to say something no Special Agent should ever say.
“Even so… isn’t this a bit rushed? Maybe it’d be better to prepare a little more…”
Kang Biso shook his head firmly and cut me off.
“No. If anything, now’s our best shot.”
Of course it was. I knew that. And yet, I couldn’t shake the worry gnawing at me.
I’d never felt like this, even when other teammates were sent on missions far more dangerous than this one. I guess Kang Biso had burrowed deeper into my heart than I’d realized. Just the thought of something happening to him made my chest tighten.
My mind filled with worst-case scenarios, and before I knew it, my face had darkened. Noticing the change, Kang Biso gently took my hand and whispered.
“Don’t worry. I’ll come back safe.”
“…Then maybe I should go with you—”
“No. Absolutely not.”
He cut in before I could even finish. That soft look on his face disappeared in an instant, replaced by a stern, unyielding expression.
“I’m glad you care. Really. But I can’t let you come.”
“I already told you—I used to be a Special Agent. I won’t slow you down.”
“It’s not about that. If anything happens to you—even just a little—I won’t be able to focus on the mission or the Book of Wishes. So please, don’t worry about me. Just wait for me to come back.”
There wasn’t anything else I could say. I wanted to stop him, to keep him from walking into danger alone. But we needed that book. We needed it desperately.
“…Hyung?”
He gave my hand a gentle tug, and I let my head fall onto his shoulder. Kang Biso stiffened at the sudden closeness, but once he realized how anxious I was, he carefully wrapped his arms around me and pulled me in tight.
His warmth seeped into my body, and the fear that had been coiled inside me slowly began to unravel.
…Isn’t there anything I can do for him?
Maybe if I could just sit in on the strategy meeting, I’d feel a little more reassured. I hated this—having no role, no way to help, just waiting. I used to be a damn good agent. I wasn’t used to being this powerless.
But no matter how hard I tried, I couldn’t think of anything. What could I possibly do?
As Kang Biso held me close, gently patting my back, something finally came to mind—I hadn’t Guided him once since I got here.
…Maybe I should Guide him.
His condition had been stable. He never asked, so I’d forgotten about it. But he’d be pushing his powers hard during the mission. Right now, the only thing I could offer him… was Guiding.
With that thought, I started Guiding him, slowly, from within his arms.
“…Hyung?”
Surprised by the sudden energy flow, Kang Biso pulled back a little and looked straight into my eyes.
“I’ll Guide you. So you can come back safe.”
“…Hyung.”
His gaze softened, filling with emotion. I reached up, pulled him by the neck, and kissed him. His lips parted slightly, and his tongue slipped into my mouth.
“Nnngh…”
Our tongues tangled naturally, melting into each other. The soft, sinuous rhythm deepened, becoming more urgent. His tongue grazed my teeth, then pressed against the roof of my mouth, exploring me thoroughly.
Maybe it was the effect of the Guiding, but he grew more desperate, more intense.
“Haa… Ha…”
“…Hngh…”
The kiss broke, but only for a moment. His lips trailed down my neck, warm and greedy. The sensation of him sucking hard on my skin made me tremble, my body flinching instinctively under his touch. He wasn’t even Guiding aggressively, and yet every little touch made my skin burn.
“…Hyung. Lift your arms.”
His voice was low, rushed—borderline commanding. As if hypnotized, I did what he said, raising my arms. In one swift motion, he pulled off my shirt. Before I could even register the cool air on my skin, his hot hands were gliding down my chest, slowly traveling lower.
He stripped off my pants and briefs in a blink and gently pushed me down onto the bed.
“Kang… Biso…”
“Hyung… haa…”
Kang Biso, who had moved up between my legs, spread them open and stared at my erect cock with eyes gleaming like a predator savoring its prey. I could clearly see the movement of his throat as he swallowed hard—so clearly that I found myself gulping unconsciously as well.
Unlike when he had stripped me earlier, this time he slowly exposed himself. As he pressed his body against mine, he wrapped one hand around both our shafts and began pumping them together in a fast, rough rhythm.
“Ahh!”
It was hot—blisteringly so. The heat radiating from Kang Biso, combined with the electric pleasure of each sharp movement, left both my body and mind feeling like they were melting into a hazy blur.
“Kuh!”
I couldn’t hold back. I came hard, streams of semen splattering across both our stomachs. As I panted, dazed in the haze of orgasm, the scene unfolding before me was obscenely erotic. Before I realized it, Kang Biso had gathered up the cum with his fingers and began pressing into my entrance, stretching me open. My softening cock twitched, then quickly sprang back to life.
“Ahh!”
Kang Biso’s fingers, already well acquainted with my insides, moved with an urgent and almost feral pace. There was no trace of gentleness in his touch, and the combination of faint pain and intense pleasure made my body tremble. Still, something about it left me unsatisfied. I glanced up at Kang Biso—he was biting his lower lip, brows drawn in frustration. I took a deep breath and, summoning my strength, pushed him away.
Startled, his eyes widened, but he obediently leaned back as I continued to push. I climbed on top of him.
“Don’t move. Just stay like this.”
“Hyung, wait—just a second…”
“Tonight, I’m the one making you feel good.”
I wrapped my fingers around Kang Biso’s cock and stroked it a few times. His eyes wavered, his face turning visibly red.
“Ha… If that’s what you want, then I’ll gladly accept. But… are you sure you’re okay?”
Kang Biso, flushed up to his neck, asked while biting his lip. Seeing him beneath me, struggling to stay sane even as he worried about me, stirred something primal deep inside. I smirked, curling the corner of my lips.
“Then behave. Got it?”
Bracing myself, I planted my knees firmly and steadied my body. This was my first time taking the lead, and the nerves were hitting me hard. Kang Biso’s intense gaze only added to the pressure, making me question whether I’d just done something incredibly reckless. But the heat in my eyes—already clouded with lust—was fixated on his cock.
“Hah…”
Slowly, I began to lower myself onto him. But he was so thick, it didn’t go in as smoothly as I’d hoped.
“Ugh…”
How had he managed this in the past? I tried to remember, my breath coming in shallow pants. Right—just a bit more. Widen my legs. Take it slow. I pushed myself down again, forcing the tight ring of muscle to stretch open.
“Ah, hng… uuh…”
It was harder than I’d expected. I tried to act confident, but I was struggling. I glanced down at Kang Biso and froze.
I knew he was watching me—but not like this. His gaze was scorching, predatory, devouring me as though just looking at me could make him come. Was this what it felt like to be violated by someone’s eyes?
Overwhelmed by the surging pleasure, I forced my body to relax and finally managed to take all of him in, his cock sinking in to the base.
“Ahh!”
I could feel him all the way inside me—deeper than usual—making my entire body tremble. A tingling sensation radiated up my spine, reaching the tips of my hair.
I needed to move. I wanted to move. But it felt like something dangerous would happen if I even twitched. I wanted to make Kang Biso feel good. But all I could manage were tiny, trembling movements—small rolls of my hips, slight shifts back and forth.
Then Kang Biso, who had been watching silently, gripped my waist tightly with both hands. His voice came out rough and strained.
“Hyung… I’m sorry. I can’t take it anymore.”
Before I could respond, he thrust his hips up—hard.
His cock slammed into that sweet, sensitive spot inside me with terrifying precision. My vision sparkled and spun.
“Ah, hng!”
With every relentless thrust, his length drove so deep it shook me to my core. I couldn’t keep my balance. My flailing hands landed beside his head, and my upper body tipped forward. The angle shifted, changing everything, and I gasped, completely lost.
Kang Biso reached up, pulled me down, and kissed me.
My body collapsed against his, flush skin to skin. My cock rubbed against his stomach with each movement, slick with precum, adding friction to every thrust. His kiss devoured me, stealing the little air I had left.
“Ahh, mm… mm!”
My mind went blank. All I could think about was the need—no, the desperation—to keep feeling more. Maybe that’s why, without realizing it, I started to move in sync with him, matching each of his powerful thrusts.
“Fuck, Hwang Dae-heon!”
He growled my real name like a beast in heat. Or at least, I thought I heard it—honestly, I wasn’t even sure. But the second I heard that voice, I came again.
“Wait—Kang Biso, I… I’m cumming!”
I shot another thick load onto his stomach, but he didn’t stop. If anything, the combination of orgasm and overstimulation twisted the pleasure into something terrifying. It was too much—so intense it felt like my body might fall apart.
But I couldn’t ask him to stop.
It felt too good.
I only realized Kang Biso had climaxed as well when I felt the heat spill deep inside me. I thought that would be the end.
But instead of slowing down, he shifted our position—and started moving again. The rhythm changed, the angle shifted, and the feverish pace resumed.
Caught in the cycle of relentless pleasure, I eventually lost all sense of time… and consciousness.
