Hurry up and put it in already.
Having spent his whole life in front of cameras, Eun-jo knew exactly how to move his body to look stunning. When he bent lower at the waist, his ass arched up enticingly. His shirt slid down naturally, revealing the soft swell of his chest, full and inviting.
Jung Tae-seok stared down at the provocative sight, then pulled out his cock. Veins bulged along its thick length, pulsing as it gave a heavy twitch.
“Relax, Hyung.”
The swollen head—easily the size of a child’s fist—pushed into the tight hole, struggling to break through. Eun-jo gasped, eyes flying open at the overwhelming sensation of being split apart.
“……!”
It felt even bigger than the night before—like it had grown somehow. The stretch inside was painfully vivid. Eun-jo could barely catch his breath, choking and gasping as Jung Tae-seok rubbed his waist reassuringly.
“You need to breathe. How are you going to take it all if you’re like this?”
“……Hhng, nngh…”
“You said I could, didn’t you?”
Tae-seok was struggling too. The way Eun-jo’s insides clamped down made it nearly impossible to hold back. Swallowing his desire to ram in deep, he held himself at the entrance, slowly grinding his hips.
The tip pressed insistently against the tight opening, like it was forcing a path forward. Every time the inner walls stretched, muffled whimpers—nngh, mm!—slipped from Eun-jo’s lips.
“Didn’t you say you were sorry…?”
He whispered, nibbling lightly on Eun-jo’s earlobe.
“Then spread open and take all of my cock.”
In the next instant, he slammed in with a single brutal thrust. A wet, bone-deep sound followed as he forced his way into a place he should never reach. Eun-jo threw his head back and screamed.
“Haaah…! Ah, ahhngh!”
The pressure deep inside him was unmistakable—Eun-jo could feel his organs being pushed aside. It honestly felt like if he opened his mouth, that massive head might come bursting out.
Jung Tae-seok didn’t give him even a second to adjust. He pulled out to the very tip, then grabbed Eun-jo’s waist tightly to keep him from escaping—and drove his hips down hard.
“Haa, nnngh—ahh!”
Thrust, thrust! His cock slammed in brutally, mercilessly. He fucked him like it was the only thing he knew how to do, burying his thick shaft deep into Eun-jo’s tight heat. As his walls sucked and clung hungrily, Tae-seok repeated the motion—grinding in deep, then retreating just to the tip before shoving it all back in again.
It hurt, and it felt good. So good it ached. Every time that thick, swollen head slammed into his core, a wave of electric pleasure hit him hard. Eun-jo came without realizing, panting harshly, saliva dripping from his lips.
“Hnnngh, nngh—ah, ahhh! Haaah!”
Squelch, squelch, squelch!
The lewd, wet sounds of skin-on-skin echoed shamelessly through the corridor. This was the Training Center—they weren’t even trying to hide. But somehow, that made it worse. More thrilling. Like they were sneaking around outside, fucking where anyone could walk in.
The thought that someone like Yeo Eun-jo—shy, reserved, always proper—had his legs spread like this, in public, just for him… it was enough to make Tae-seok lose his mind.
Eun-jo’s wanton body trembled with every thrust. Each time Tae-seok drove into him, his hole clenched and fluttered, sucking at him with obscene greed.
“You feel that? How soft it’s gotten?”
Tae-seok murmured the words low, burying his cock to the base inside the wet, yielding heat.
“You’re leaking around my cock. You love taking it, don’t you.”
“Hhnn—nngh, mmn…!”
“Squeezing me like you never wanna let go.”
He brushed a fingertip over the stretched rim, and Eun-jo’s hips jerked violently.
“Want me to put this in too?”
“N-No, wait—ahhh, nnngh!”
Tae-seok didn’t wait. He pressed his finger beside his cock, forcing it into the impossibly tight space. Just when it seemed like it couldn’t open any further, his finger slipped inside.
A second finger followed, stretching him to his limit. When he rubbed the spot inside, Eun-jo’s back arched hard, eyes flying open.
“Haaah—ngh! A-Ah, ahh!”
His vision blurred white. Eun-jo trembled violently as his hole clamped down, and for the first time, Tae-seok’s expression faltered. He thrust in with savage force, his fingers twisting ruthlessly, balls slapping hard against Eun-jo’s ass.
Tae-seok’s large frame swallowed him whole, chest flush to back with no space between. He drove his hips again—thud, thud—each time that thick cockhead punched deep into his guts.
“Next time, even if it hurts… you’ll spread your legs for me again, right? Hmm?”
“Nnngh—mm, ah! Ahh!”
Eun-jo couldn’t even think. He moaned mindlessly, too far gone in the overwhelming pleasure. Tae-seok leaned in, biting down on his neck like he was punishing him for not answering.
“Why aren’t you answering me, Hyung?”
“Hnn—ahh!”
“Say it properly. Or I’ll bend you over in the lab next time and fuck you there instead.”
“H-Haaah! If it hurts—I’ll still spread them… if Tae-seok wants it—mmn, ahh—yes!”
Even through his sobs, Eun-jo said exactly what Tae-seok wanted to hear.
“Ahh—nngh! I’ll spread them anywhere… ah, ahhh!”
His face must’ve been flushed so deep red it looked like he’d die of embarrassment, soaked in sweat and tears, lips trembling as he moaned. Without hesitation, Tae-seok pulled his fingers free and flipped him over.
Just like he imagined—Eun-jo’s face was wrecked, dripping wet with tears and sweat. His cheeks were burning, lips red and swollen. It was obscene how beautiful he looked like this.
Tae-seok scooped him up easily, muttering low:
“Hold your legs.”
Eun-jo obeyed, grabbing his thighs and spreading himself open—and the moment he did, Tae-seok rammed back in.
Thrust, thrust! His cock plunged between those soft, bouncing cheeks with each motion. And this time, he didn’t hold back at all. His hips pistoned hard and fast, slamming into Eun-jo with brutal precision.
The moans tore out of him louder than ever.
In that moment, every plan in Eun-jo’s head vanished. No ambition. No dream of becoming an S-Rank Guide. Nothing.
Just the thick cock pounding into him over and over, each thrust lighting his nerves on fire.
He sobbed, overwhelmed, and took it all.
“Haa, haaah! A-Ah! No, Tae-seok—mm, mmngh!”
Like he was hanging off a cliff, Eun-jo wrapped both arms tightly around Tae-seok’s neck. Their chests pressed together, firm abs crashing into each other. With a low, feral growl, Jung Tae-seok shoved his cock all the way in—deep to the base.
Pleasure shot through Eun-jo’s body like a lightning strike. His insides burned, searing hot, as Tae-seok groaned and spilled his release deep inside him.
“Hnnngh, nnf, ahhh…!”
Eun-jo trembled uncontrollably, head falling back as Tae-seok pulled him in tighter. When Tae-seok began to slowly thrust again, stirring the cum-filled heat, Eun-jo let out a choked moan and collapsed against his shoulder.
Tae-seok lingered inside him for a long moment, like he couldn’t get enough. Then, with a slow pull, he withdrew. The swollen hole, still stretched and gaping, dripped with release that splattered thickly to the ground.
“Tae-seok…”
The soft, fragile voice made him glance down. Eun-jo’s eyes were half-lidded, dazed, like he was only half-awake—yet still looking right at him.
Slowly, Eun-jo lifted his hand. When his fingers brushed Tae-seok’s cheek, Tae-seok—surprisingly—let it happen without flinching.
“Are you okay now…?”
“Who’s worrying about who here?”
“I’m the one worrying about you.”
Eun-jo gave a small, tired smile, blinking slowly as he fought to keep his eyes open.
“You really aren’t hurt… right?”
He wasn’t letting it go. If Tae-seok didn’t answer, he’d probably keep staring like that all day.
Holding his gaze, Tae-seok gave a curt reply.
“…Yeah.”
The moment he heard it, Eun-jo relaxed completely. His body slumped, and Tae-seok caught him instantly, pulling him into his arms.
For a second, Tae-seok looked surprised—then let out a long breath when he realized Eun-jo had fallen asleep.
This wasn’t like him. Yeo Eun-jo had never cared much about Guiding, never gave a damn if it worked or not. So what the hell was this sudden shift?
What frustrated him even more… was how much this new Eun-jo was getting under his skin.
“Seriously… did he eat poison or something?”
Why was he acting like this? Why the hell was he doing shit he’d never done before?
Grumbling to himself, Tae-seok adjusted his grip, cradling Eun-jo more securely.
He stripped off his shirt with a single motion and draped it over Eun-jo’s hips. No way was he letting anyone see what he’d done to him—how raw and swollen he’d left him down there.
The residual pulse of Guiding energy had finally settled. As it faded, Tae-seok walked out of the alley.
He passed through the wrecked Training Room, making his way toward the exit—when a silhouette came into view.
Jin Mu-seong, Team B’s leader.
Dressed in a perfectly tailored suit that barely contained his hulking build, the man looked like he’d just come from a board meeting. The muscle straining under that fabric didn’t look human.
Fucking monster.
Tae-seok was considered large within the Center, but next to Jin Mu-seong, he looked like nothing.
Unlike what many expected, Jin Mu-seong had awakened as an A-Rank, not S. That result had landed him as Team B’s captain. People at the Center treated him like some washed-out reject from Team A.
But Tae-seok didn’t see it that way.
His eyes narrowed, studying the man. Jin Mu-seong didn’t fit words like “failure” or “castoff.” Not even close.
There was something off about him—something poised. Composed. Something that didn’t match the A-Rank title.
Right now, with his hands casually stuffed in his pockets, Jin Mu-seong was staring straight at Eun-jo, still limp in Tae-seok’s arms.
His expression was… puzzled. Like he was seeing something that didn’t add up.
Like he should’ve been the one holding that body instead.
“…Fucking annoying.”
“I can hear you just fine, Esper Jung Tae-seok.”
Jin Mu-seong’s shoes clicked against the floor as he approached, slow and deliberate. He glanced over Tae-seok’s shoulder, whistled low at the wrecked arena behind him.
“So much for inter-team courtesy, huh?”
“The Training Room’s made to be destroyed, isn’t it?”
“Not wrong,” Jin Mu-seong replied, letting out a faint chuckle. “Didn’t expect anyone to take it that literally.”
His gaze dropped—then lingered.
“You even did a penetration Guiding session in there.”
His eyes landed on the back of Eun-jo’s head.
For a man who didn’t blink even when a Gate erupted in his face, Jin Mu-seong’s eyes now glinted with interest.
“Didn’t know that was your thing.”
He was only here because Team A’s leader was away, and someone had to check on the Training Center.
What he’d seen in the observation room was unforgettable—two people tangled up like animals in the alley.
Eun-jo clinging tight, sobbing, moaning, refusing to let go.
Where the hell did this one come from? It was almost strange that Jin Mu-seong hadn’t noticed him until now.
“Or is that his kink? Yeo Eun-jo’s?”
“It was an emergency Guiding.”
“Emergency, huh.”
Jin Mu-seong let out a dry chuckle. He could still hear the echo of moans from earlier.
“Sure.”
He didn’t plan to stop them. Not yet.
Jin Mu-seong stepped aside, letting them pass.
“Submit your report.”
“I’ll report directly to my team leader.”
Tae-seok passed him without letting down his guard for a second.
Even as they vanished from sight, Jin Mu-seong’s gaze never left them.
The way he watched them—cold, steady, and fixed—like a predator zeroing in on prey.
