Without a single moment of hesitation, Yoon Seoho told a bold, deliberate lie—and to make sure it landed, he slammed his palm down hard across the boy’s bruised bottom. The sound echoed sharp and loud.
SMACK!
“H-Heick… ah… a-ahhn… heugh!”
“And here I thought you were just an innocent little thing. But really, you’re nothing more than a worn-out street whore. Isn’t that the truth of what you are?”
The cruel words kept pouring out of him, one after another—each one carefully chosen for a reason. Right now, it was absolutely necessary to rebuild a solid wall of secrecy around Seo Yuan.
Just minutes earlier, the boy had reached out and touched a common house slave without permission. That was a direct violation of the rules—he had acted without his master’s approval.
“It looks like our precious Yuan still doesn’t understand what he did wrong…”
Leaning down until his chest was pressed flat against the boy’s trembling back, Yoon Seoho lowered his voice to a deep, dangerous whisper right next to his ear.
Seo Yuan’s whole body jolted violently.
The thick length inside him had suddenly shifted direction, pressing at a strange, awkward angle against the deepest part of his insides.
“H-Heugh…!”
“You’re still just a fragile little child, so you have no idea that this isn’t the end of the road inside you.”
Muttering the strange words into the boy’s dark hair, Yoon Seoho used the hard tip of his shaft to push firmly and steadily against the tight, unyielding barrier that led to the deeper part of the colon.
Completely confused about why his master was relentlessly ramming against what felt like a solid wall, Seo Yuan could only let out frantic, scared whimpers. His face was twisted in bewilderment.
“Ugh… a-ahhn… h-haa…?!”
The strange, aggressive pressure didn’t stop for even a second.
With each harsh thrust aimed at breaking through that inner gate, the boy’s lower body was lifted clean off the table. The force was so strong that the heavy dining table shook and groaned like it was about to fall apart.
But Yoon Seoho didn’t seem to notice or care about any of that.
Driven by a single, focused urge—like a predator chasing a scent underground—he kept slamming his shaft against that inner wall again and again.
And then—it finally gave way.
The tightly sealed ring of muscle that guarded the boy’s deepest part slowly began to stretch and open under the relentless pressure.
The moment he felt it start to give, Yoon Seoho’s eyes lit up with a fierce, hungry gleam.
“Pay close attention, Yuan. This is the exact spot.”
Pressing his whole body flat against the boy’s back, he eliminated every bit of space between them, throwing all his weight into that single point. The hard head of his cock wedged itself into the small gap in the muscle.
With a thick, wet, tearing sound, the deep gate collapsed open, allowing his entire length to slide smoothly into the uncharted depths of the colon.
“H-HAAAAAA!”
Seo Yuan’s eyes flew wide open, his pupils rolling back until only the whites showed. His face was a perfect picture of absolute shock and agony.
Once he was sure he was fully seated inside that deep chamber, Yoon Seoho pulled back just a little—then drove himself back in with brutal speed.
BANG!
“H-HEICK!”
“Ha… ‘fuck’…”
A harsh, guttural curse escaped Yoon Seoho’s lips.
The inside of Seo Yuan’s colon was far tighter and narrower than any other partner or toy he had ever used. The fit was so incredibly snug it almost felt wrong—every tiny fold of the inner walls wrapped around him with unyielding pressure. The suction was so intense that his shaft felt like it was about to burst.
“A-Ahhn… h-heugh… ah!”
“……Shit.”
“H-Hick… h-heiu!”
He had only thrust once into that deep place, but his body was already screaming that he was about to reach his limit.
Yoon Seoho ground his teeth together harshly and forced himself to breathe steadily again. It would be humiliating to lose control like some common street dog before he had even properly explored this new territory.
Clenching his jaw, he pulled his shaft almost all the way out—then slammed it back in with a heavy, echoing thud.
“A-Ahhn!”
Yoon Seoho glanced down at the spot where the dark, stretched skin was struggling to take in his thick shaft. The slick fluids—mixed with the boy’s earlier release—were spilling out like a waterfall. A few drops splashed up and landed on Yoon Seoho’s cheek.
“You look just like a desperate, open-mouthed little bitch, Yuan. Haah… ‘fuck’.”
He tossed out the crude words as if they meant nothing, while his hips kept driving into the boy with savage rhythm.
He didn’t pay any mind to how badly the boy was trembling against the wood. His only focus was on punishing that tight, stubborn chamber that kept trying to clamp down on him.
“I had planned to save this part for later in your training. But you keep refusing to do what I tell you.”
That was the truth. According to his original plan, he was going to wait until the boy was fully used to regular backdoor penetration before trying to go this deep.
But if he was being honest with himself, his sudden rush was fueled by a growing sense of urgency.
Part of it was certainly the boy’s unauthorized contact with the slave—but there was something much bigger underneath.
The simple truth was this: Seo Yuan’s powers were growing far too fast for Yoon Seoho’s comfort.
He knew very well that the person pinned beneath him was the living body of a higher being—an artificial vessel made by bringing a dead shell back to life. But he had never expected that this fragile, broken doll would be able to completely heal a crippled human body.
Erasing the deep, incurable mental decay that all S-rank Espers suffered from was already an unbelievable miracle—yet the boy had just done something even more extraordinary.
When Yoon Seoho had watched that incredible act of healing inside the temple, his mind had been genuinely shaken.
