The sharp clack of leather shoes echoed through the empty hallway.
The motion-sensor lights, which should have flickered on with movement, stayed silent. As a result, only the green glow of the emergency exit cast a dim light across the corridor. The man walked through the silence without a shred of hesitation, as if he knew this place like the back of his hand.
He didn’t belong in a backwater center like this. There was no reason anyone here would be dressed in a full three-piece suit. And that massive frame of his—there wasn’t another like it in any center across the country.
Jin Mu-seong. He came to a stop right in front of Yeo Eun-jo’s room.
With minimal effort, he disabled the security system and pushed the door open. Sure, an alert would ping the security team, but that would only matter once the time-freeze lifted. He didn’t care.
Inside was a modest apartment with a living room, kitchen, and single bedroom—just right for a newlywed couple starting out. Jin Mu-seong’s brow lifted.
“Two mugs, two pillows…”
As he strolled through the living room like he owned the place, he stopped short.
“Only one bedroom?”
A crooked smirk tugged at his lips. If Eun-jo had seen it, he would’ve called it villainous—and it would’ve sent a shiver down his spine.
When he opened the bedroom door, he saw them. Two people, curled up together like spoons, facing the same direction. One holding the other close.
Leaning against the doorway, Jin Mu-seong stared down at the sleeping pair. His smirk was already gone.
“This is even more disgusting than I thought…”
His eyes gleamed in the dark, sharp and cutting—like the flash of an emergency light in the gloom.
Thirty-four years old. Not once in his life had Jin Mu-seong ever lost control. He kept his dangerous abilities carefully concealed. He’d chosen to lead Team B instead of putting himself out front in Team A. Always calculating, always in control. That’s how he’d survived.
But that small, delicate Guide had wrecked everything.
Lately, he’d been like a teenager in the throes of a first crush—unhinged, unable to keep his emotions in check. Just like now.
What irritated him more than the stifling air in the room were the details—the matching pairs of slippers by the bed, Park Se-yul’s arm casually wrapped around Eun-jo’s waist, and the relaxed, content look on Eun-jo’s face.
The idea that they might actually be emotionally compatible irked him more than the fact that their bodies were entwined.
He stepped closer and yanked Eun-jo toward him. Then, with rougher hands than before, he threw Park Se-yul’s arm aside like it was nothing.
Eun-jo’s cheeks were plump—clearly eating well, living well.
“He’s not even cute,” Jin Mu-seong muttered, brushing a hand through Eun-jo’s hair.
“Baby.”
“……”
“I’m pissed. Aren’t you going to do something about it?”
His fingers slipped under the pajama hem. As he popped open the buttons, Eun-jo’s marked skin was revealed.
Jin Mu-seong’s eyes lingered on the nipple piercings—delicate bells glinting against soft, pink skin.
“Tch…”
He didn’t need to ask who had chosen those.
“Fucking hell,” he spat, stripping Eun-jo’s clothes with swift, practiced hands.
He turned him over, checking his inner thighs, waist, and ass—before letting out a low curse. His large palm gripped the curve of Eun-jo’s butt, still bearing the faint imprint of Park Se-yul’s hand.
He dove in without hesitation, pressing his face into the soft flesh.
His lips latched on, sucking hard, as if erasing the marks would make them disappear. Wet, lewd sounds echoed through the room.
“Mmng…”
Eun-jo let out a breathy moan in his sleep and shifted slightly.
When Jin Mu-seong pried the cheeks apart with both hands, the swollen, flushed entrance came into view.
Clearly, it had been used—and used well.
His gaze sharpened as he traced a finger along the rim.
“You’re really gonna sleep through this while your boyfriend’s licking you?”
“Hhngh…”
“It’s our first night as a couple, baby.”
He shoved three fingers in at once. The entrance took him in with ease. Unlike before, when he had to open him up finger by finger, it was slick and loose.
He curled his fingers and gave a sharp twist. The inner walls twitched around him.
“No response? Then I’ll just shove my cock in. How’s that sound?”
“……”
“Baby.”
“……”
Still fast asleep, Eun-jo only let out soft, steady breaths.
With a dark grin, Jin Mu-seong yanked his fingers out.
“Hiiik…!”
The hole twitched again, almost begging to be filled. He lowered himself down.
With his towering frame, he completely blanketed Eun-jo’s smaller body. Wrapping his arms around his waist, he lined himself up.
His thick head pushed past the swollen rim. In one smooth, deep thrust, he filled Eun-jo to the hilt.
Eun-jo gasped sharply in his sleep, breath catching. At the same time, a deep groan slipped from Jin Mu-seong’s lips.
“Haa… fuck… this feels so good…”
He was scorching hot. Maybe it was because he was fucking a body still half-asleep, but Eun-jo felt even warmer than usual. As Jin Mu-seong moved his hips slowly, the inner walls clung to him instinctively—recognizing their master and wrapping around him in welcome.
Every time he thrust in, Eun-jo’s soft ass was pressed flat, and their pubic hair brushed together. The sound of skin slapping echoed through the room, and Mu-seong exhaled roughly, his tongue gliding up the curve of Eun-jo’s neck.
“Hhn… mm… ah…”
Just picturing the moment Eun-jo woke up—realizing what was happening, feeling his belly being stirred from the inside—was enough to make Mu-seong even harder. He imagined those wide eyes looking down, watching himself being split open. First he’d be horrified, then those moans would return… lost in pleasure.
“Tch… ah, aahh…!”
He ground the head of his cock against the slick inner walls, and a sweet moan spilled from him. Slowly, teasingly, he hit the sensitive spots—then picked up the pace.
He yanked Eun-jo’s hips up to get a better angle, then wrapped a solid arm around his waist and started thrusting hard. With every slam into that tight space, Eun-jo’s moans grew louder.
“It’s our first night, and already…”
Mu-seong muttered, pulling out just enough for the swollen rim of his cock to rest at the entrance.
“You’re this loose already? Seriously?”
The thick head, barely hanging in, drove in deep—slamming all the way to the back.
His cock shoved into Eun-jo’s colon in one hard thrust, and Eun-jo’s whole body trembled, legs shaking in response.
But Mu-seong didn’t stop. He kept slamming into the now-slick opening, pounding into him mercilessly.
His hand slid down over Eun-jo’s stomach.
“Didn’t know I was this fucking possessive.”
“Hhnng… ah…”
“But you… you made me jealous.”
He tugged the bell piercings on Eun-jo’s nipples, and the already pink areola flushed a deeper red. Eun-jo winced, his face tightening with pain.
What the…
The strange sensation pulled him out of his daze. Eun-jo’s eyes fluttered open, adjusting to the darkness. His body was being rocked back and forth—thrust after thrust. Arms were wrapped around his waist, and that relentless pressure from below…
He realized what was happening.
“T-Team Leader… hngh, y-you said you’d stop earlier…”
Just then, the thick head grinding inside him pushed even deeper, breaching the final inner wall.
Eun-jo held his breath, unable to even gasp.
“Hhnn…”
“Team leader?”
A large hand fisted in his hair, yanking his head up. His neck snapped back, and his eyes finally landed on Park Se-yul—still fast asleep beside them.
“Look closely. Your team leader’s right there. Sleeping like a baby.”
The familiar voice sent a jolt through him. Eun-jo’s eyes went wide in disbelief.
Jin Mu-seong grabbed his waist and dragged him forward, pulling him off the bed.
He positioned Eun-jo so Se-yul was directly in front of him, plain to see.
“Now take a good look. See who’s fucking you right now.”
Thrust.
He rammed in to the base, wrapping around Eun-jo from behind.
The motion pitched Eun-jo’s chest forward, causing his nipples to bounce. Jingle. The bells attached to them gave a soft, humiliating sound.
Mu-seong’s face darkened.
“You need to know, baby.”
“Aaah…! Ngh… mmngh…!”
Eun-jo bit down hard, trying to stifle the moans, but they still slipped out.
Every time Mu-seong thrust in, his belly clenched, and his heels lifted off the floor.
“When did you…? Ngh, if the team leader wakes up…”
The thought of Se-yul waking to this sight—seeing him like this—sent a chill through him.
Normally, someone as sensitive as Se-yul would’ve woken already, but Eun-jo’s mind was too scrambled to think straight.
“No, wait… please, wait…! Hngh, baby, just—just a second…!”
He squirmed, trying to escape, but Mu-seong locked both arms around him, holding him tight.
“Let him see. Let him see you getting filled.”
“Nghh… ah, ahh…!”
“Only then—” thrust “—will you know exactly who you belong to.”
His eyes flicked down to the bells dangling from Eun-jo’s nipples.
“You won’t pull this kind of bullshit again.”
Realizing that Mu-seong had figured out he was trying to wake Se-yul, Eun-jo finally broke. Tears streamed down his face.
He couldn’t escape—not from Mu-seong’s hold, not from the overwhelming pleasure.
All he could feel was the cock drilling deep inside him, driving out every other thought.
