Without a moment’s pause, Lee Sang-heon drove his hips forward. The flushed head of his relentless cock pressed and rubbed against the trembling entrance of Yeo Eun-jo’s colon, tormenting him with every grind. Each thrust in and out made Eun-jo’s vision blur. A maelstrom of desire and fear swirled inside him, torn between wanting more and dreading what was coming. Moaning like a beast in heat, Eun-jo collapsed onto the floor.
“Ungh, uh, ah! Ahhh…! Right there—hah—cum inside me…!”
“No.”
Lee Sang-heon’s voice was firm as he wrapped an arm tightly around Eun-jo’s lower belly.
“You’ve got to take it deeper if you want to get pregnant.”
With that, he forced Eun-jo upright, plunging even deeper inside. As Eun-jo squirmed and tried to flee, Sang-heon gripped him tighter and started moving his body with unrelenting force. Each time he hoisted him up and slammed him back down, the tight rim of his colon stretched open.
“Haaah…! Ahh! Ahh!”
Finally, his entrance gave way, and the swollen head slipped inside. The pressure of being spread open, the sensation of his insides being rearranged—it made Eun-jo cry out, eyes flying open in shock.
“Ah, it’s hot… Darling…”
The cock inside felt like it was melting into him. The scorching, thick flesh grinding against his walls made Lee Sang-heon throw his head back with a moan, savoring the sensation. Fighting the urge to release too soon, he kept thrusting, hips moving with grim determination.
“Ah, ahh! Hngh! Uh!”
“You like getting fucked like this?”
“Uh, ah, ahhh…”
Even through his breathless moans, his trembling hole clenched tightly around the cock, clearly begging for more. Sang-heon pushed down hard, sinking his shaft in to the base until his pubic hair met Eun-jo’s flushed skin.
“You’ve got to take the cum in if you want that baby, right?”
Thud, thud! Violent slaps echoed in the room. His ass, now glowing red, was pounded mercilessly as the thick cock stirred his guts with raw force.
It didn’t feel like lovemaking. It was primal, feral—like a beast mating. Lee Sang-heon’s thrusts had no rhythm or finesse, just brutal, breeding thrusts, deep and merciless.
“Hngh, ah! Ahh! Ah…! Cum—hah—please cum inside me…! Yes! Uh, ah!”
Eun-jo’s body trembled with each brutal upward thrust. He felt like he was losing his mind. His lower belly was swollen as if he was already pregnant, and a clear liquid—not cum, not piss—leaked freely from his hole. It was colorless, scentless. As it dripped onto the floor with a splash, Eun-jo screamed.
He couldn’t take it anymore. Face flushed and trembling, he turned to look at Sang-heon.
“Hngh, uh, please…! Yes?”
“Hah… You gonna get pregnant?”
“Yes, uh! Haah…! Hurry…!”
Eun-jo guided Sang-heon’s hand, placing it over his belly.
“Right here… Hurry up and cum inside…!”
There was no way he could resist his begging bitch. Sang-heon crashed their lips together, locking Eun-jo in a desperate kiss as he clutched him even tighter.
Thud! With one final thrust, the swollen head pierced deep into Eun-jo’s gut. The sharp, tearing pleasure surged through him, and even his cries were swallowed into the kiss. Hot liquid spurted deep inside, flooding his twitching hole.
There was so much—it felt like it could’ve been a full bladder. It sloshed with every twitch. Only when his cock finished pumping did Sang-heon finally release his lips.
“Hah…”
Just as Eun-jo was about to respond to the lazy kiss trailing down to his lower lip, he felt something pulse inside.
“Uh, hngh…?”
The cockhead, still buried inside him, started swelling. As the glans expanded, his already-stretched rim screamed in protest. Like a plug sealing in the load, the knotted tip swelled to trap the cum inside.
It felt like his body was tearing apart all over again. His belly swelled and nausea crept up his throat. It was even bigger than before—like someone had shoved a baby’s fist inside. Clutching his lower belly, Eun-jo whimpered.
He couldn’t breathe. It felt like the cock might pop out of his mouth from sheer pressure. Gasping, he looked back at Lee Sang-heon in alarm.
“Haahhh…! Uh, w-wait, hngh, my stomach feels weird…!”
“It’s your baby belly, darling.”
Still locked inside him, Sang-heon gently turned Eun-jo’s body.
“Ahhh…! Uh, if you move…! Ah!”
Now facing him, Sang-heon kissed his cheek gently. As if to soothe him, he whispered sweetly while Eun-jo let out pitiful, broken whimpers.
“Just a little, okay?”
“Ah, hngh…! H-how much…?”
He looked impossibly adorable, even while squirming in pain. Lee Sang-heon pressed a kiss to the corner of Eun-jo’s tear-brimmed eye and murmured something utterly horrifying.
“I’ll just leave it in for half a day.”
His tone was gentle, but the cock buried deep inside was anything but. It was obscene—huge, unrelenting, brutal. As the head swelled even more, Eun-jo’s neck arched back involuntarily. His lower belly had rounded, bulging like he was carrying something inside.
***
Time lost all meaning.
Every time he opened his eyes, he was somewhere else. Moments ago, he’d been writhing on the cold cave floor. Now, water lapped softly against his hips. It looked like a nearby lake. As he blinked groggily, a low voice drifted to his ears.
“You’re up?”
Lifting his head, he found Lee Sang-heon gazing down at him with quiet affection. Cradled like a child, Eun-jo was wrapped in his arm, held with ridiculous ease.
“You slept a long time.”
“Not like I had a choice…”
Eun-jo muttered, resting his cheek against that broad chest. His body felt boneless, drained. The insides of his thighs and his ass stung like they’d been whipped, and his belly still felt unbearably heavy.
Wait… heavy?
“No way. Don’t tell me—”
He looked down—and froze.
They were still connected. The thick, flushed shaft was still lodged inside him, the same one that had wrecked him all night.
“W-When did you even— You…!”
The moment he clenched his abs, his inner walls spasmed tight. Sang-heon groaned low and gripped Eun-jo’s thigh, hard.
“Does it matter?”
He whispered as he slowly pushed his hips upward.
“Hah… You’re clenching like you missed me.”
“W-Wait…!”
He could feel everything—the massive head dragging through his colon, pressing against the entrance with terrifying clarity. When he saw the outline of Sang-heon’s cock bulging beneath his flat belly, Eun-jo nearly blacked out.
It felt like getting blindsided.
That soft, fluffy puppy—the one who used to bring him snacks with tail-wagging devotion—had been fucking him for hours. He couldn’t believe it.
I was so good to him…!
He was the only team member who brushed his fur, who petted his head every time they met. Feeling betrayed, Eun-jo sank his teeth into Sang-heon’s chest—unaware it only turned him on more.
“It’s always been this way.”
As if to help him bite deeper, Sang-heon gently cupped the back of his head and murmured,
“Since the moment you became my Guide.”
“Haaah… Ngh—ah! A-Ah! Aaah!”
That weapon-like tip rammed past the entrance to his colon. His inner walls, clinging tight, stretched wide with a slick, obscene sound. They expanded with no resistance, slick and raw. As he thrust in deep, Sang-heon groaned at the way Eun-jo’s body clung to him.
“Nnngh—ah! Aahhh…!”
It felt like dying. With every thrust, Eun-jo trembled all over, like his body didn’t even belong to him anymore. Gasping, moaning, he opened his eyes and mouth wide, choking on air like he was drowning. Normally, hearing the word Guide would’ve thrown him—but right now, his mind was too far gone to care.
Drenched in pleasure, he could only moan. Spreading his thighs wide to take him deeper, Eun-jo wrapped his arms around Sang-heon and pulled him in tight.
“Mmgh, ngh—ah! Aahhh…! Sang-heon!”
“Hah… I’ve wanted to mate with you since the beginning.”
He slammed Eun-jo’s trembling body down hard, driving himself in to the hilt. His cock rammed deep into the narrow passage, the massive tip forcing its way into the colon. It was so big, it sealed him completely—like a plug, not a drop of cum would escape.
“Aaahhh! Ah! Aaahh!”
His vision went white. Pleasure unlike anything he could handle tore through him, and Eun-jo convulsed, eyes rolling back. Clear fluid gushed out from between his legs.
It was only his second time cumming today.
