The memory of Adam clinging to him with both legs, hips moving desperately, was still vivid.
Given how skilled he’d been, Isaac had assumed he was experienced.
“You’re surprised too, right? I was shocked when I first heard it.”
“W-Wait, ah—ugh…!”
“Who’d have thought it was his first time? Tch, look at this bold one. Going this far to cure his sister’s illness—how touching.”
Chester’s voice dripped with amusement rather than sincerity.
His eyes sparkled like stars, and Isaac swallowed a dry laugh.
“Right, so bold. A man who’s never even slept with anyone, volunteering to get pregnant.”
Chester nodded, then pushed his cock deeper inside.
The thick shaft slid in slowly, forcing the tight ring of muscle to stretch.
Drops of slick trickled from the stretched entrance.
“Ah—hah… it hurts….”
The strained whimper brushed against Isaac’s ears.
Adam’s panting, trapped between pain and pleasure, looked pitiful.
As Isaac watched his heaving back, Chester whispered:
“Touch him.”
“What?”
“Stroke him—help him relax. And while you’re at it, find his sweet spots.”
Chester’s voice was playful.
“I already found mine.”
He raised a hand and tapped his own ear.
Isaac immediately understood: Adam’s sensitive spot is his ears.
When his expression shifted in realization, Chester’s smile deepened, smug with satisfaction.
That smirk irked Isaac.
He knew it was childish, but he obediently moved his arm anyway.
His palm spread wide, gliding slowly down Adam’s back.
A damp sheen—sweat or something else—coated his fingers.
“Hng… ugh….”
“Breathe, Adam. Holding it in helps no one.”
“S-Sorry… I c-can’t… relax… ah….”
As they spoke, Isaac kept caressing him—firm, persistent strokes.
His hand drifted lower, rubbing circles over Adam’s abdomen before creeping upward.
The tip of his index finger flicked over a nipple.
“Hyuk!”
Adam shuddered violently.
Isaac’s eyes gleamed in understanding.
He traced the areola with his fingertip, and Adam trembled even more.
So here’s his weak spot.
No surprise. Even during their first time, Adam’s chest had been unusually sensitive.
Sucking the soft bud into his mouth had made Adam gasp and writhe.
Biting the areola had drawn out choked, pleasure-soaked whimpers—pain laced with unmistakable arousal.
The memory flashed behind Isaac’s eyes: those nipples, red and swollen from relentless attention, stiff and glistening, tempting enough to devour.
Oddly, his mouth watered just recalling it.
“Why…?”
Adam suddenly spoke, voice ragged.
His flushed face tilted up, eyes hazy.
“Why… keep touching me…?”
The breathless plea was pitiful. Isaac gripped the back of Adam’s head and pushed it down.
“Focus. You haven’t even taken him all the way yet.”
“N-Not… all the way?”
Adam muttered in disbelief, “No way….”
Daring to doubt a duke’s word?
Isaac almost retorted but stopped.
The sight of Adam trembling between the two brothers stirred something strange—pity, yes, but also a creeping heat.
Instead of scolding him, Isaac lightly tugged the damp strands of his hair.
A hint of lavender wafted up—had he oiled it? L
ost in thought, Isaac trailed his hand lower.
As his fingers traced the feverish curve of Adam’s neck, Chester suddenly chuckled.
He winked at Isaac, then gripped Adam’s hips and slammed the rest of his length inside.
“Hhk—!”
Adam’s breath hitched.
Beneath Isaac’s palm, he felt the frantic pulse of Adam’s jugular—thud, thud, thud—like his veins might burst.
“Hah.”
Chester sheathed himself to the hilt.
Pale pubic hair pressed against Adam’s ass.
The sudden stretch seemed too much—Adam gagged, overwhelmed.
“G-Gonna… split… ah….”
At those words, Isaac grew curious.
Could it really burst?
It was true that his brother was larger and thicker than average, but he wasn’t sure if it was enough to rupture someone’s stomach.
His long fingers trailed down Adam’s throat.
“Hah—”
Adam let out a startled sound—Isaac had just brushed his lower abdomen.
For a moment, Adam twisted his shoulders as if to resist, but then he went limp, as though realizing it was pointless to struggle.
Press, sink.
“Ah, hh—hng… P-please, don’t push, Sio…”
“It really is bulging out. Fascinating.”
“Huh?”
Adam’s voice was laced with shock.
Strangely, Isaac felt an unfamiliar playfulness rise in him—something he hadn’t experienced since early childhood.
“I’ll touch it.”
His tone flat, he tugged Adam’s wrist.
Adam staggered, nearly losing balance, but Isaac caught him firmly with his other hand.
Even so, he didn’t stop guiding Adam’s hand to press against his own stomach.
“Ah… Ah…”
“Can you feel it?”
The question came from Chester.
As he spoke, he pulled his cock back slightly before thrusting back in to the hilt.
The head must have struck a sensitive spot—Adam’s hips jerked.
“Well? Answer me. Can you feel my cock?”
“Nn—ugh…”
“Hah, why is it so tight? I can barely move.”
Adam clutched his lower abdomen, squeezing his eyes shut.
Isaac forced his hands back to the floor.
Only then did he notice his clothes were soaked through.
I hadn’t even planned to touch him.
It was strange—he hadn’t expected to participate so actively.
Isaac studied the wet fabric clinging to his arm.
The sensation wasn’t entirely unpleasant.
“The first movements should be slow. Think of it as prying open a closed wall. Let the head carve the path.”
Thrust, thrust.
Chester moved his hips deliberately, spreading the tightness with each drag of his cockhead. Isaac’s eyelids grew heavy.
The memory of that hot, velvety grip around his own length flared vividly in his mind.
“Hng—!”
“Pull out slowly too.”
The cock buried deep inside retreated at a languid pace.
“Some people feel it more when it’s pulled out. We should see if Adam’s the same.”
Chester’s lips curled in a silent addition:
It’ll make tormenting him even better.
The smirk was pure mischief.
Isaac didn’t scold him—he wasn’t exactly known for kindness either.
“Why would it feel better when pulled out?”
“The drag is what does it. When it feels like your insides might follow? That’s the best part. Here—like this.”
Chester pushed halfway in, then pulled back out.
Adam’s hips arched off the floor.
Seizing the moment, Chester released his waist and instead gripped Adam’s ass, spreading him wide.
The stretched hole gaped, glistening under the light, unable to close even after the cock slipped free.
“Hmm.”
Chester was smiling—a beautiful, eerie thing, tilted at one corner.
“Our Adam feels it every way, huh? Sure this is your first time?”
His cock, fully erect now, slid back in effortlessly—until it suddenly stopped.
Chester took a slow breath and glanced at his brother.
“There’s a raised spot inside. Did you know?”
“…I did.”
“Of course you did. Figured it out from the start?”
“It’d be stranger if I hadn’t.”
Isaac paused, steadying his breath before speaking again, voice low.
“I could feel it with just my fingers. Pressing there made him writhe.”
“Then I don’t need to teach you. I was going to say—rubbing the tip against that spot drives him wild.”
Swish, slide.
Chester’s hips moved fluidly, surely grinding against that swollen inner ridge.
Adam pounded the floor with his fists, back arching.
By now, his own cock stood stiff between his legs.
“Ah—ah, hah…”
“Adam, how does it feel?”
Sshhk, ssweek.
Amid the lewd friction, Chester brought his lips to Adam’s ear.
“Feels good?”
“Hng…!”
“You should answer honestly.”
The lips that had just spoken now traced the curve of his ear.
Then, with a soft “Huu…”, a breath blew against it—Adam’s shoulders jerked.
So it was true that his ears were sensitive.
Isaac watched with fascination as Adam’s body trembled each time those lips pressed insistently against his earlobe.
The light flickering in those crimson eyes grew heavier, more intent.
“Ah, nn—!”
