His hand moved with the rhythm of deep, plunging thrusts. It slid down to the back of Eun-jo’s throat and then pulled back to the lips, again and again. With each merciless movement inside his mouth, muffled moans escaped from Eun-jo’s trembling lips.
“Looks like I need to retrain your mouth.”
His other hand gripped Eun-jo’s cheek roughly, prying open his slack lips. Without pause, he shoved his hand deep inside once more.
“Open up when something goes in.”
“Haaaup…! Ugh, heup…”
“And like this, when it comes out.”
He whispered as he slowly stroked the soft, quivering tongue.
“You’ve got to purse your lips and tighten them. Don’t let your tongue touch it.”
Eun-jo, panting heavily, nodded. In response, he received a light tap on the cheek before his body was pulled downward.
“Huuu…”
Click. The belt came undone, and something sprang free beneath it. Eun-jo blinked in disbelief.
What the hell is this?
It looked even larger than before, as if his lower body were still growing. Thick veins bulged along the surface, giving it a grotesquely powerful appearance.
Absentmindedly, Eun-jo’s lower lip brushed against the swollen tip. A moment later, it pushed past his lips.
“Huu…”
Heat and slick pressure filled his mouth, the guiding energy flooding his senses. He moaned softly.
He already knew the shape by touch alone—he could trace its structure with his eyes closed. As the glans pushed deeper inside, Eun-jo gasped and instinctively opened his throat.
“Good.”
Despite the brutal pace, the praise came in a gentle voice as he began to move his hips slowly. Just like with his ass, his mouth was ruthlessly penetrated. Lewd squelches filled the air, and saliva trickled from the corners of Eun-jo’s gaping mouth.
Each time it filled him, he couldn’t breathe. His eyes turned red, and his lips split open at the edges. But even as Eun-jo’s face twisted in a teary, ruined mess, Park Se-yul didn’t stop moving.
It felt too good—so dangerously good. The sight of Eun-jo wrecked beneath him, the obscene tightness of his throat… it was overwhelming. Se-yul thrust harder, hips driving with force as he gripped his ass.
“Heup, ugh, hooep…”
Eun-jo opened his mouth wide, panting raggedly. Then, desperate to take more of him in, he tilted his head back and let his throat open. The glans slid deep, stretching the narrow, hot passage as it went.
“Keuk, ugh, haheup…! Hooep…!”
His hips moved without mercy, like he was using a toy to get himself off. Every deep thrust made Eun-jo choke, tears spilling freely.
He couldn’t breathe. Before he could inhale properly, the thick head slammed against his throat and cheeks. Hands still bound, Eun-jo writhed helplessly.
Just before his eyes rolled back, Se-yul finally pulled out.
“Shit…”
He muttered a curse, rubbing his glans against Eun-jo’s limp, soaked lips.
“Yeo Eun-jo.”
“……”
“Eun-jo. Look at me.”
At the soft command, hazy eyes slowly turned to him. The way he looked up—like a pet recognizing its owner—made Se-yul’s lips curl into a wicked grin.
“Let’s get your punishment started.”
He flipped Eun-jo over with ease. Wrapping both arms around his waist, he pulled him close.
Face pressed to the bed, ass raised high, it was the perfect position for penetration. Se-yul brought the glans to the twitching entrance and used his other hand to grip Eun-jo’s lower body—more specifically, the plug inserted in his urethra.
“Pee. Right here.”
“Huh, ugh…?”
Before Eun-jo could protest, the plug was yanked out.
“……!”
The sensation was vivid. The sudden emptiness made the urge to urinate surge violently. Eun-jo bit his lip, trying to hold it back.
“No—I can’t. I can’t do that…”
On someone else’s bed, in someone else’s dorm, he couldn’t. His shame drowned him. He shook his head desperately, looking up at Se-yul with pleading eyes.
“Please… please, Team Leader…”
“You should’ve been ready for this.”
A large hand gripped his lower body tightly. Huik! Something leaked out, and Eun-jo clenched with all his might.
“I was wrong…! Huik, I can’t…!”
Se-yul stroked his trembling lower body slowly. The mix of humiliation and stimulation unraveled his control. What had only trickled before now poured freely like an opened faucet.
“No, I can’t…!”
His flat abdomen quivered. What now? Panicked, Eun-jo tried to cover himself, but Se-yul pinned him down and slid into position.
The tip pressed against the puckered entrance. Then, with a punishing thrust, it drove inside.
Eun-jo arched, head thrown back in a silent scream.
The narrow passage, untouched and unbelievably tight, parted for the thick intrusion. Flesh clung tightly to the invading shaft. With a deeper thrust, Se-yul buried himself and made Eun-jo cry out.
“Ah… ahuu…”
His cock rammed in without mercy. Even though there was clearly no more space, his lower body kept driving deeper, making Eun-jo’s belly bulge outward. The sensation of his insides being shoved aside and his deepest parts stretching was all too real. With every jolt from Park Se-yul’s relentless thrusts, streams of urine sprayed from Eun-jo’s trembling body.
“Relax. Or do you want to bite my cock off?”
Slamming into his ass, Park Se-yul yanked Eun-jo’s upper body upright. With his cock still buried deep inside, the shift in position made it feel like he’d plunged even further, and Eun-jo let out a hoarse scream.
Still holding him tightly, Se-yul began pounding upward with heavy thrusts. Each time the thick head slammed home, liquid trickled from the front. A heady mix of shame, release, and pleasure washed over Eun-jo’s shuddering body.
“You’re dripping from both ends now, huh?”
“Hik, ugh, ah… aah…!”
“Leaking from your ass too, Yeo Eun-jo.”
He pulled Eun-jo’s bound hands down and guided them to where their bodies were connected. As Eun-jo felt the wet mess down there, he gasped sharply.
“Feel it. See how much you’re spilling out.”
He could feel it—feel the shaft sliding in and out, slick and soaked. It was buried so deep that his pubic hair brushed Eun-jo’s skin before the thick glans would slide out again. Just picturing what it looked like drove him mad with shame and arousal.
And the fluids—they weren’t just imagined. The whole area was soaking wet. The sensation of that heat and wetness beneath his fingers made the pleasure spike even higher.
“Ha, fuck… you’re getting wet again.”
There was no way Park Se-yul, who was pistoning into him, didn’t notice. He tightened his hold around Eun-jo’s lower abdomen and drove his hips forward with savage force.
“Ahuup…! Ugh, ah—it’s leaking—it’s leaking from my ass…! Ahik…!”
“You like it when I press here, don’t you?”
“Ugh—yes, yes…”
Every time that thick, swollen tip jabbed inside, his vision flashed white. His toes curled, and his entire body trembled uncontrollably. As if he knew exactly where to hit, Park Se-yul kept attacking all the spots that made him moan. The bulging veins rubbed like ridges, adding another layer of unbearable stimulation.
His body had already become more sensitive after peeing once. Now, with each thrust, he jerked like a puppet, his bladder emptying in spurts. Moans burst from his lips without warning, and his flushed body shook from head to toe.
“I should’ve claimed you a long time ago.”
Se-yul muttered as he flipped Eun-jo onto his back.
“I’ve been way too generous to everyone else.”
He spread apart the snowy white cheeks, revealing the hole stretched wide around his cock. It was fully opened, barely clinging to the thick shaft. When he touched the flushed pink rim with his fingers, it twitched under his touch.
“Don’t you think it’s about time I took what’s mine?”
He pushed the glans against the sensitive inner spot, making Eun-jo gasp.
“My team belongs to me.”
“…Hng!”
“And you’re the guide of my team, Yeo Eun-jo.”
He drove in with quick, shallow thrusts, each one striking the sweet spot dead-on. The insides squirmed around him, clamping down greedily. Watching the hole twitch and squeeze, he moved his hips faster, deliberately shallow to drag out every bit of friction.
“Tighten up properly.”
Even though the tightness was already overwhelming—borderline painful—he pretended not to notice and slapped Eun-jo’s ass.
Slap, slap. The sound of skin smacking against skin rang out sharply in the room. With every hit, the hole clenched tighter.
“Hik, ugh—it hurts…! Ah, ahik…!”
“Tighter.”
Red handprints bloomed on his skin. The sting of each strike sent Eun-jo writhing, torn between agony and ecstasy. It hurt—felt like his flesh was splitting—but bit by bit, even the pain began to blur into pleasure.
