The venom clouded the mind, twisting thoughts and desires into fantasy—A perfect illusion, tailored to each victim’s longing.
In the original story, Park Se-yul had experienced a master-servant kink.
Jung Tae-seok got trapped in a captivity fantasy.
The tricky part was that the protagonist of this fantasy world—Lee Sang-heon—must never find out it was all fake. Because of the toxin seeping into his mind, the moment he realized the truth, it would deal a devastating blow to his psyche. The only way out was to end the illusion as quickly as possible. In reality, both of them were probably dying from the poison already.
In other words, Eun-jo had no choice but to play along with Lee Sang-heon’s fantasy. If it had been Park Se-yul or Jung Tae-seok, he might’ve at least been able to guess the setting. But with Lee Sang-heon? The only fantasy on record was some knotting scenario—there was nothing else to go on.
This is gonna be a nightmare.
While Eun-jo rolled his eyes, Lee Sang-heon strode confidently into the cave.
Unlike before, the inside was surprisingly cozy. The walls glowed with luminous stones—who knew where he found those?—and there was even a fireplace-like structure tucked into one side. Lee Sang-heon walked past it and gently laid Eun-jo down on a circular bed made of straw and grass.
“Wife.”
He stared at Eun-jo for a moment, then slowly shifted into his human form.
“I told you, you’re not alone anymore.”
“……”
“You’re carrying our pup. So don’t run off, alright? My wife.”
“P-Pup…?”
Startled, Eun-jo glanced down at his body. Beneath the white T-shirt, his lower belly was noticeably swollen.
Swollen…?
He’d never had a belly before. Ever since debuting as a child actor, he’d obsessively managed his diet. If he gained even a little weight, he’d fast for two days straight to get rid of it.
Sure, he’d overeaten before—but this felt different. Just as his trembling hand reached for his stomach—
“I told you we’d have a pup.”
At some point, Lee Sang-heon had knelt beside him and was now lifting his T-shirt. The soft pink of his areola peeked through, and the slight swell of his belly was impossible to miss. Lee Sang-heon gently stroked it, as if checking to make sure it was okay.
“Mine.”
“……”
“My mate.”
As Eun-jo looked down at his own stomach, he squeezed his eyes shut. Now he finally understood what Lee Sang-heon’s fantasy was.
You’ve got to be fucking kidding me.
Beasts naturally formed packs—it was instinct. The novel had hinted at it in passing, but if he was supposed to be the one giving birth to that pack?
That changed everything.
“You, you…!”
Eun-jo stammered, lips trembling. He wanted to scream, to demand answers—but he couldn’t.
“Did we… really make this together?”
“Mhm.”
Lee Sang-heon nodded as he gently bit down on Eun-jo’s fingertip, like he was answering the most obvious question in the world.
“I put my seed in you right here, remember?”
“……”
“You don’t remember?”
Of course he didn’t. Because it never happened. But Eun-jo couldn’t even respond—he just sat there, stunned.
Lee Sang-heon moved before he could react. In an instant, Eun-jo’s pants were stripped off, and a large hand slid over the inside of his thigh and cupped his ass. His face might’ve looked dazed, but his gaze was anything but—he was examining every inch of Eun-jo’s body with meticulous attention.
No injuries. Tilting his head in curiosity—an oddly innocent gesture for someone his size—Lee Sang-heon pulled up Eun-jo’s shirt even further. Then he froze, staring intently at something.
“Here.”
Lee Sang-heon’s fingertip lightly tapped Eun-jo’s chest.
“Why did it go back in?”
He furrowed his brows, like something serious had gone wrong. Between the pale pink areola, the nipple had retracted. That wouldn’t do. Frowning, he gripped Eun-jo’s chest firmly with both hands.
“You’re supposed to feed the pup.”
“Ah…! Wait!”
His chest was completely engulfed in Lee Sang-heon’s large hands. The soft flesh spilled out between his fingers, and the areola deepened in color. But when nothing came out, Lee Sang-heon leaned down and latched on without hesitation.
Like biting into ripe fruit, he took a full mouthful of flesh. A faint sweetness spread across his tongue. Milk hadn’t come in yet—so why did it taste so sweet? Eyes glinting, he sucked even harder, drawn in by the flavor he couldn’t quite describe.
“Nngh, mmn…!”
The suction sent Eun-jo’s head falling back. A tingling pleasure surged up from his toes. Without realizing it, he grabbed a fistful of silver hair, soft moans spilling from his lips.
Lee Sang-heon suckled as if truly feeding for a while, then changed his approach. Now he coaxed instead, flicking the nipple gently with the tip of his tongue. His other hand tugged lightly at Eun-jo’s breast, making his voice rise even higher.
“Ahh, ngh… mm…!”
“Push it out, wife.”
He spoke against his skin, lips brushing as he nipped lightly with his teeth.
“How else will the pups feed?”
“Hngh, ah… ahh…!”
“Push it out for me, yeah? We need to practice now.”
Maybe it was the pregnancy, or maybe it was just something about the Gate—but just from having his chest sucked, Eun-jo’s head was spinning. When he flinched, Lee Sang-heon rolled the areola slowly with his tongue, urging him again.
“Come on.”
Face flushed deep red, Eun-jo hesitated, then finally pushed his chest forward. As hot as his cheeks, the swollen flesh was once again taken fully into Lee Sang-heon’s mouth. He rolled the nipple with his tongue, scraping it softly with his teeth. A cry slipped out.
“Mmm, ahh… yes, that feels good… hnngh…”
Even the stinging pain blurred into pleasure. Eun-jo’s hips twitched. To Lee Sang-heon, no female was ever ugly—not even when pregnant. The round, heavy breasts, the softly swelling belly, and the slick heat dripping between Eun-jo’s legs… he wanted to devour it all.
He fought back the urge to spread those legs and thrust in right now. Instead, he kissed Eun-jo gently. When his tongue licked at the inside of Eun-jo’s mouth, the other responded instinctively, tongue curling around his.
“Mmh… ngh…”
He kissed him sweetly, hand twisting at his chest. Then he gave a sharp tug—and the hidden nub finally peeked out.
“Ah… haa…”
When he pulled back, a string of saliva stretched between them. Stroking the plump tip like praise, Eun-jo moaned, eyes glazed and dazed.
“Wife.”
“Hnn… mmh…”
“Did your cock get hard just from pushing your nipple out?”
Gripping the erection below, Lee Sang-heon made Eun-jo jolt with a sharp gasp.
“Ah! D-Don’t touch that…! Hnnngh!”
“Oh? You like that?”
Pleasuring his mate was part of the male’s duty. Pressing kisses to Eun-jo’s cheek like he was soothing him, Lee Sang-heon slowly began to move his hand.
“When I stroke you like this…”
As he brushed over the same flushed pink tip as Eun-jo’s nipples, the other’s eyes flew open. He gasped again.
“Hhhnn…!”
“You really like it.”
His large hand wrapped tightly around him, no space left between. As he began stroking faster, slick wetness poured from Eun-jo’s arousal, dripping with every pump.
“Ahhh—ahhhngh…!”
His touch was relentless. No teasing, no drawn-out foreplay—just raw, primal urgency. Unlike anyone else, his hands moved with the sole purpose of breeding, driven by instinct rather than lust.
And that made it all the more overwhelming.
Eun-jo moaned as his back arched uncontrollably. Heat rushed through him, and his lower belly tightened like a coiled spring ready to snap.
“Hnngh, ahh—w-wait…! Nnngh, mmn…!”
His vision went hazy. Mouth falling open in a helpless gasp, Eun-jo spread his legs wide like a frog, trembling all over. And then—he came.
Hot release burst from him, splattering across Lee Sang-heon’s hand, his own belly, and his thighs. But Lee Sang-heon didn’t seem fazed in the slightest. Without hesitation, he leaned down and swallowed Eun-jo’s cock whole.
“Hhh—!?”
Eun-jo, limp and dazed, lifted his head just enough to see—Lee Sang-heon had him in his mouth, sucking.
“D-Dirty… ahh, aah…! I-It’s all messy, but—nngh, uhnnngh…!”
Like a hungry pup nursing, Lee Sang-heon gripped his shaft with both hands and sucked greedily. Eun-jo’s still-sensitive tip brushed against slick, hot mucosa, and his mind blanked out all over again.
“Ahh—ahh! Haa…!”
Only after drinking down every last drop did Lee Sang-heon finally lift his head.
“Mine. My mate.”
“Hnngh… mmn…”
In the dim light, those silver eyes glinted. He gave Eun-jo’s cock a light tap, voice low and possessive.
“Hurry up and give birth to our pup.”
“……”
“I want to put another one in you.”
Licking his lips at the lingering sweetness, he clicked his tongue in satisfaction. His own cock was already painfully swollen, pressing against his lower belly—but he didn’t go any further.
Not yet.
He couldn’t. Not when his mate was already carrying his pup.
