The shadow lifted from Eun-jo’s face, and the moment Lee Sang-heon noticed, his tongue began to move downward. It traced a path along Eun-jo’s neck, dipping lower until it reached his chest. Like a predator skilled in the hunt, he effortlessly pulled up the knit sweater, revealing soft pink nipples beneath.
“Hey, Lee Sang-heon…!”
Before Eun-jo could protest, Lee Sang-heon latched onto his chest with a deep, greedy mouthful.
Carefully keeping his sharp teeth hidden, he suckled hard, wetting the sensitive nub. Chup, chup. As the tender bud was completely engulfed, Eun-jo writhed beneath him.
“Hngh, wait—just wait a second…”
He tried to push him away, but before he could, a firm paw slammed down, pinning his wrist to the floor.
“Ugh…!”
Lee Sang-heon leaned in, pressing his weight over him, eyes gleaming—not with affection, but with something feral. This wasn’t the gentle touch from earlier, when he’d been licking Eun-jo’s cheek. Now, his gaze gleamed like a predator toying with weaker prey.
A siren blared in Eun-jo’s mind. Every instinct screamed that if he moved again, he’d be devoured. Logically, he knew—this wasn’t a real wolf, but an Esper from Team A. Yet his body trembled, refusing to believe it.
Even glancing away felt dangerous, like it might get his throat torn open. Eun-jo gasped and kept eye contact, and only then did Lee Sang-heon move.
He returned to the now slick, saliva-soaked nipple and took it into his mouth again. This time, he let his teeth graze it lightly, tongue teasing the tip. Eun-jo whimpered, pained.
“Haa… ngh, it hurts… ah…”
He bit just enough to leave a faint mark, then licked it over as if savoring it. Was a Guide always this sweet? Every time he sucked and coaxed the swollen nub, a faint sweetness bloomed in his mouth. He continued, sucking eagerly until his desire calmed, swirling his tongue with slow, deliberate strokes.
He moved lower, past Eun-jo’s abdomen, toward an even more private place. Just above his waistband, the gleam of a metal belt caught the light—a flashy piece Eun-jo had picked up at a department store. Lee Sang-heon growled in frustration. It was too clunky to yank off with his foot.
“Grrr…”
“Wait, wait—don’t bite it!”
Eun-jo’s panicked voice rang out.
Then, Lee Sang-heon’s body began to stretch, shift—until in the blink of an eye, he was human again.
Now looming above him was a man with tousled gray hair, as if white fur had been dipped in ink. His long hair flowed over a sculpted chest, and sunlight danced in his gleaming silver eyes.
With sharp ears poking through his hair, he looked unreal—an ethereal beauty that stole the breath from Eun-jo’s lungs. Eyes wide, Eun-jo murmured,
“Lee… Sang-heon…?”
At his name, Lee Sang-heon’s gaze locked onto him. Without replying, he deftly unbuckled the belt and pulled down Eun-jo’s pants, spreading his legs.
In that instant, a memory struck—something from the novel. The scene where Sang-heon and the protagonist had their first time. Eun-jo’s face drained of color.
“W-Wait!”
He still had to face Park Se-yul tonight. There was no way he could end up tangled with Lee Sang-heon here, now.
Especially not like this…
Desperate, Eun-jo grabbed the nearby chocolate bar and waved it like a lifeline.
“H-Here! Let’s eat this together…”
“……”
“You told me to rest, remember? This—this isn’t resting.”
He shook the chocolate with everything he had, voice pleading. Lee Sang-heon’s eyes followed the motion of his hand.
Yes… that’s it.
Just as Eun-jo began to breathe in relief—
Thwack.
Lee Sang-heon grabbed his wrist. The chocolate slipped from his hand and hit the floor with a dull thud, echoing like the sound of his own heartbeat crashing down.
“I want to.”
The words came slow, spaced out, like a child still learning to speak.
“Here.”
“……”
“Wanna rub.”
And then Eun-jo saw it—rising thick between Lee Sang-heon’s thighs. It was flushed a deep, furious red, shaped almost inhumanly. The head was grotesquely large—too big for comfort.
That’s… going to get even bigger?
Forget the Imprint—if that thing grew inside him, he was either going to die or be torn apart.
Neither option sounded survivable. Eun-jo’s eyes darted desperately around for escape. But Lee Sang-heon only repeated himself, calmly.
“I want to.”
“You really… really mean just rubbing… right…?”
Lee Sang-heon nodded solemnly, then grabbed Eun-jo and flipped him over without another word. He positioned him on all fours—knees bent, hands flat against the floor like an obedient pet. As Eun-jo tensed, rigid with nerves, Lee Sang-heon climbed on top and licked his nape softly.
“Hnngh…”
Slowly, the thick shaft pushed between Eun-jo’s thighs. Terrified he might suddenly change his mind, Eun-jo clenched his legs tightly together. Lee Sang-heon groaned, biting his shoulder.
He thrust between Eun-jo’s thighs, grinding with slow, heavy movements. Friction turned Eun-jo’s pale inner thighs a flushed red, and his own cock, already stirred, began to harden fully.
“Ugh… ahh… mmgh…!”
“Fuuuck… feels good…”
Groaning low in his throat, Lee Sang-heon suckled the shoulder he’d just bitten. As their skin pressed together, something began to flow—energy, unstable at first, but gradually calming. The chaotic waves of tension smoothed out, replaced with rising heat and trembling sensation. The deeper that energy pulsed through them, the wilder Sang-heon’s gaze became.
He wanted more. Wanted to bury himself deep inside. To slam his cock in and fuck him until he came, until he filled him to the brim and made him bear his child. He wanted to hold him down by the shoulders, grip his hips tight, and thrust in until Eun-jo’s ass couldn’t take any more…
“Hnngh, ah! Aah, it’s so hot…!”
Instead of cumming inside, Lee Sang-heon gripped Eun-jo’s lower belly with both hands and pulled him in tight. Thrust. Thrust. His hips snapped forward in a relentless rhythm, grinding hard between Eun-jo’s thighs.
Each slap of skin-to-skin contact sent heat flaring between Eun-jo’s legs. Every time that thick cock slid through his thighs, his entrance twitched, his belly jerking with the sensation.
“Hnnngh, ah—ahh! Aaah!”
Cheeks pressed against the grass, Eun-jo rocked his hips in time with the thrusts, unable to stop himself. The fact that he was getting off with someone who’d just been a dog—right here in the garden, in that raw, animalistic position—sent a forbidden thrill straight to his core. He felt like a bitch in heat, rutting shamelessly in the open.
“Wanna breed you.”
“Ah—ahhng! You said—just rubbing, nghh…”
“Wanna fill you. Fill you with my seed.”
Lee Sang-heon squeezed his belly harder and rutted faster between his thighs. Their cocks rubbed together, slick and hot, and Eun-jo’s toes curled, pleasure tightening his whole body.
“Ugh… mmnh… aah!”
“Feels good. Feels so good…”
Lee Sang-heon murmured in a daze, mouth pressed against his skin, leaving hickeys and bite marks across his shoulders. Pulling Eun-jo into his lap, he wrapped one large hand around both of their shafts and started stroking—fast, rough, desperate.
Eun-jo gasped, head falling back, breath hitching with every stroke. The friction was dizzying, overwhelming. His lips parted on a moan, hips twitching forward helplessly.
“Haaah… ngh… I—I’m gonna—!”
With a cry, thick spurts of cum shot from his cock, splattering across his chest and stomach. Only after spilling every drop did Eun-jo’s body finally slump, breath ragged and body trembling. His chest heaved, nipples raw and swollen from earlier bites.
Lifting his head slightly, he glanced down—and saw it. Lee Sang-heon’s cock, still hard, still pulsing. Veins bulged so thickly it looked painful.
“…Should I help you out?”
He asked gently, cautiously. But Lee Sang-heon shook his head.
“We said just rubbing.”
He knew he wouldn’t be able to finish without being inside. What he wanted was simple—to press into Eun-jo’s belly and keep thrusting until he bred him properly, until his seed took root.
But Yeo Eun-jo wasn’t his mate. Not yet. And taking someone without permission went against even a beast’s instincts. With a reluctant sigh, Lee Sang-heon let it go—and shifted back into his beast form.
“Lee Sang-heon?”
Gone was the stunning man from moments ago. In his place, a massive dog padded over, tail wagging. Though, of course, that monstrous cock was still dangling obscenely between his legs.
“You turned back into a dog?”
Eun-jo chuckled weakly, reaching out to ruffle the thick fur on his head. But Lee Sang-heon climbed onto him again, pressing his weight against Eun-jo’s belly.
“Ah—hey…!”
The pressure made Eun-jo squirm and giggle, the ticklish sensation too much. Lee Sang-heon licked him clean, making sure not a single drop of his cum remained. Then he leaned down and gave a soft kiss to Eun-jo’s spent cock before flopping onto the grass, clearly satisfied.
Eun-jo, drained and dazed, lay down beside him.
Sang-heon’s probably the easiest of them all.
As an Esper, Lee Sang-heon had drifted closer to beast than man. His senses, his body—they were hypersensitive, animalistic. Even his instincts followed that path.
In the novel, his reason for Imprinting was simple. The moment he recognized his mate, he’d thrust deep, tie them down, and mark them from the inside.
That thing gets even bigger…?
Eun-jo stole a glance at the thick, dark red cock still standing like a weapon. It hadn’t softened at all.
Now’s not the time.
If he let that thing inside, he’d be out of commission for days—and the other Espers wouldn’t sit quietly while he recovered. It could throw off everything. Swallowing hard, Eun-jo silently pushed Lee Sang-heon’s turn to the end of the list.
Hearing the sound, Lee Sang-heon cracked an eye open and used his tail to cover his still-erect cock. Then, like a pouty child, he pressed a soft paw—jelly-like—against Eun-jo’s nose.
“…I didn’t ask for it.”
Eun-jo muttered in protest, but Lee Sang-heon pressed his paw against his nose again, more firmly this time.
“Mmgh.”
“I said I didn’t—!”
Lee Sang-heon’s tail flicked in mock irritation as he closed his eyes again, ending the conversation.
And all that remained was Eun-jo—completely, utterly exasperated.
