What Park Se-yul needed wasn’t just a spark—it was a detonator to blow apart the dam holding back his suppressed desires.
All throughout training, Eun-jo had been subtly feeding those urges, stoking them like coals. He knew Se-yul needed a proper trigger—and so, without hesitation, he turned to his only ally: Jin Mu-seong.
“You always come to me with the fun stuff.”
Jin Mu-seong agreed right away, his tone playful. He didn’t forget to remind Eun-jo of the promised day.
Eun-jo lifted his gaze and saw the result. Park Se-yul stood before him, disheveled in a way that was entirely unlike him. His eyes were charged with dominance—the gaze of a man who had never once played the submissive role. When their eyes locked, a chill skittered down Eun-jo’s spine.
Ah… fuck.
Just looking at his sharp features and cold expression sent a pulse of anticipation to Eun-jo’s core. His silver-rimmed glasses, the cool confidence in his face—he was sexy as hell. If Jung Tae-seok had the aura of a man in a chocolate commercial, then Park Se-yul was the elegant CEO who drove housewives wild.
The hard edge of Se-yul’s heel pressing into his thigh sent a delicious shiver through him.
“As of today, you’re done as Team A’s guide.”
There was nothing left to do but follow his lead. Eun-jo’s large eyes welled up almost instantly.
“No, please… I’m begging you…”
“Don’t bother showing up tomorrow.”
When Se-yul moved to take off his shoe without the slightest hesitation, Eun-jo clung desperately to his leg.
“Please—anything but that. Huhk… Team Leader…!”
With beautifully streaming tears, Eun-jo threw out the bait. Sweet. Irresistible.
“If that’s what it takes—huhk—I’ll do anything. Anything you want. Please…”
“Anything?”
A dangerous gleam flickered in Se-yul’s eyes.
“You said anything.”
“Huh… y-yes…!” Eun-jo nodded wildly, panting, his chest rising and falling with each breath. Then, slowly, he brought his lips to the tip of Se-yul’s shoe.
He kissed it tenderly, like he was kissing a lover. His lips moved over the rounded leather, lingering as if savoring the taste, and a hot breath fell from above.
But before his lips could reach Se-yul’s ankle, a large hand grabbed a fistful of his hair and yanked his head back.
“Huhk!”
“Forget the center. You’ll get your punishment in my room.”
Se-yul’s eyes gleamed darkly, full of lust.
“We’re short on time today. So right here.”
As he slipped off his shoe, his flushed thigh was exposed. Leaning down just slightly, he ordered in a low growl:
“Wait like this whenever you’re being punished. Hands behind your back.”
Afraid he might change his mind, Eun-jo quickly tucked his hands behind him. The motion made his pink-tinged chest stand out even more.
His toes twitched. He bowed his head low, terrified that Se-yul might see just how dirty his thoughts had become.
Without warning, a large hand yanked his head up again.
“Ahh…!”
“Don’t bow your head unless I tell you to.”
“……”
“Answer me.”
“H-huhk… I’m s-sorry…”
Choking on his sobs, Eun-jo swallowed his tears. The harsh tone had frightened him—but his face, soaked in shame, was undeniably lewd.
Park Se-yul stood fully clothed and perfectly composed. Eun-jo knelt before him, naked on the cold floor. The contrast was stark—and absolutely intoxicating. Se-yul’s gaze roamed down Eun-jo’s body with slow, deliberate intent. Then he tilted his chin, pointing downward.
“Take it out.”
Eun-jo hesitated, then slowly reached for his waistband. But the hard heel dug into his thigh again.
“Ahh!”
“You don’t move unless I say so.”
With that, Se-yul grabbed a fistful of Eun-jo’s hair and pulled his face toward his crotch. Pressed between his legs, Eun-jo let out a gasp and used his lips to pull down the zipper.
The ziiik of the zipper echoed in the air. His briefs were revealed. Eun-jo bit the waistband gently with his lips. And in that moment, Se-yul’s fully hardened cock slapped against his cheek.
“Suck. I want to see just how much of a whore you’ve become.”
His lips were forced open, and the cock shoved into his mouth. Stunned, Eun-jo instinctively tightened around it, but Se-yul grabbed his chin firmly.
“Suck. Didn’t you hear me?”
“Keuhheup…”
A large hand shoved his head down again. Eun-jo opened wide and let the cock sink deep into his throat.
Huu, Se-yul let out a low groan and forced his head down even further. The hot, slick walls of his throat clung tightly around him, sending waves of pleasure coursing through him. It was beyond anything he’d experienced in a dream. He wouldn’t have been surprised if he’d melted on the spot.
With his cock buried deep in Eun-jo’s throat, Park Se-yul suddenly froze. His face twisted in strained ecstasy as his eyes bore down on him.
“Eut, euup, uu…!”
There was no room for air. His face was buried tight between Se-yul’s thighs, and even breathing through his nose was nearly impossible. Heat surged through him, and his vision started to blur. Keuk, keu… A muffled groan slipped out as Eun-jo’s fingers twitched.
Only when his sight completely blacked out did Se-yul finally let go. With a sharp motion, the cock pulled out from deep inside him. Saliva spilled from his mouth in long, glistening strands as Eun-jo gasped and coughed, lowering his head instinctively.
“I told you not to bow your head.”
“Heup…!”
Eun-jo jerked his head back up, but it was already too late. Se-yul gripped both sides of his head again and slowly drew his hips back.
Thud! With a powerful thrust, his cock slammed straight into Eun-jo’s throat, burying itself in one brutal motion. Startled, Eun-jo squirmed, but Se-yul kept moving his hips without pause.
Each time he pushed in, Eun-jo’s throat bulged obscenely. His entire face flushed a deep crimson, and tears streamed from his pained, distorted eyes. The spray of water from above blurred his vision, making it hard to even keep his eyes open. Soaked through, Eun-jo choked and swallowed desperately around the cock.
“Huhk, keup, heuk…! Keok, keup…!”
It felt like the cock was drilling down into his stomach. A tearing pain split through him, and his thoughts scattered into white noise. His head bobbed violently, like he was nothing more than Park Se-yul’s personal masturbation toy.
His smooth, porcelain skin gleamed under the shower. His chest, flushed with arousal, had deepened to a rosy pink. Water trickled down his taut stomach, winding between thighs pale as snow. Slap, slap! His lewd, dripping body rocked back and forth, and each motion only sharpened the tension in Se-yul’s clenched jaw. His stare was piercing—hot and merciless.
“Eut… you filthy little thing.”
“Keup, keue…! Uuk, uuep…”
“Opening up your back hole from the morning, tsk…”
Thud, thud! The cruel sound of flesh colliding echoed in the tiled space. With his cock buried to the base, Se-yul pried Eun-jo’s lips open even wider with his fingers.
“Uuuuk…!”
Beneath the thick shaft, his balls—full and heavy—pressed forward. Eun-jo’s lips split at the corners, a thin trickle of blood seeping out as his breath came in ragged gasps.
When both balls forced their way into his mouth, Eun-jo’s eyes rolled back. His vision tunneled, his body collapsed. And just as he reached his limit, a hot flood of semen surged deep into his throat.
“Kkuup, huh, uuep…”
Whether he wanted to or not, thick, bitter cum slid down his esophagus. Only when the aftertaste coated his tongue did Se-yul pull out.
Even post-orgasm, his still-hard cock rubbed against Eun-jo’s slack lips. Eun-jo’s eyelids fluttered closed. When his limp body finally fell, Se-yul caught him in his arms and shut off the shower.
“You did well.”
The praise slipped into his ears, soft and honeyed. Maybe it was because he was completely drained, but the words sounded oddly sweet. Eun-jo, barely conscious, shifted his gaze toward him. By then, Park Se-yul had already concealed his lust and returned to being the composed Team A leader.
“Huh, I… I’m Team A’s guide, huhk…”
“Don’t speak. You’ll only hurt yourself.”
His voice was a whisper as he gently stroked Eun-jo’s neck.
“You’ll stay as Team A’s guide—for the duration of your punishment.”
“…Huh?”
“Come to my room after training. The day after tomorrow.”
He pressed his fingertips lightly against Eun-jo’s spine. Even that faint touch made the tender skin flush red.
“If you show up with any other marks, I won’t overlook it.”
Only after that promise was set did Eun-jo finally close his eyes. And just before slipping into unconsciousness, one last thought crossed his mind.
What kind of mark would be good next time? Maybe a kiss mark on the chest?
As he mused over who might be a suitable partner, Eun-jo drifted into a deep sleep.
