At last, a clear stream shot from the tip of Ha-gyeom’s penis, soaking his upper body completely. The rigid shaft twitched again and again, spraying like a fountain. His thigh muscles tensed as if they might split, his hips jerked upward uncontrollably, and naturally, his anus clenched tight around what was inside.

“Hhngh, ngh…!”

Ha-gyeom moaned, nearly in tears. His chest, slick with the translucent fluid, gleamed under the dim light. When Baek Sa saw the sight with his own eyes, not a trace of reason remained on his face.

He released Ha-gyeom’s bent legs and lunged down over him, letting out a pained groan. Given how tightly he was being squeezed, it was only natural. He was stuck—unable to thrust deeper or pull back—and his panting breaths were rough and loud.

“Uuugh…!”

Ha-gyeom came again, another stream shooting out as he drowned in the overwhelming pleasure. His limp legs trembled, and his throat clamped shut. It felt like his body might just explode, and every inch of skin flushed red as he struggled to breathe through the spasms.

“Ngh, ahh…”

Only after the long, intense climax finally subsided did the stream come to a stop. Baek Sa, who seemed barely able to stay upright, looked down at his soaked penis, lifted it with a squeeze, and said with a hoarse laugh,

“Haa, Ha-gyeom… You nearly snapped it off…”

“Ugh! It feels… so good…”

Just a touch was enough to drive him wild, and once the real stimulation began, his toes curled on their own. Ha-gyeom gripped Baek Sa’s hand tightly, moving his hips as if begging for more. All the while, his entrance slowly relaxed, repeatedly swallowing and releasing Baek Sa’s slick penis in steady rhythm.

When Baek Sa saw the head swell with pressure, he abruptly pulled his hand away. Bracing himself against the sheets, he adjusted his position and began to move his hips in sync with Ha-gyeom’s. He only pulled out and pushed back in a few times, but the sensation was so intense that tears welled at the corners of Ha-gyeom’s eyes as he moaned in bliss.

“Hnngh… mm…!”

Soon, the sound of sharp thrusts filled the room as Baek Sa quickened his pace. Pre-ejaculate spilled from him, forming a pale foam around Ha-gyeom’s entrance that trickled down along his tailbone. With his fluid acting as lubricant, the friction grew slicker and more intense. It felt like he was teetering on the edge of pain—stretching just to the brink of tearing.

Ha-gyeom could only grip the sheets in his fists, wrinkling the fabric as he let Baek Sa guide his legs up onto his shoulders, entirely surrendered to the moment.

“Haa, I’m about to come—hold on.”

“Y-yeah…!”

As Baek Sa leaned forward, his knees pressed into Ha-gyeom’s chest. It was the deepest thrust yet. Ha-gyeom, eyes bleary and raw, could only stare up at Baek Sa’s face—sensual and restless as it moved above him.

His brows furrowed tightly, lips wet, ears flushed red.

“Haa, aahng!”

With Ha-gyeom’s legs folded against his body, Baek Sa gripped him tightly and began to thrust, groaning roughly. Thud, thud! The bed jolted under the force. His movements were wild, mercilessly pounding into the now-constricted space, and Ha-gyeom could tell—he was nearing the edge.

“Mmngh! Aah—ah!”

“Haa, ha… ah…”

The pace was unbelievably fast. Ha-gyeom’s mouth filled with saliva, and his consciousness began to blur. That strange blend of pleasure from being rubbed and prodded at all his sensitive spots—the tight, precarious stretch of an entrance that felt like it might tear at any second, and the searing heat of skin-on-skin contact—all of it overwhelmed him.

“Mmph! Nngh!”

The pleasure soared past its limit. Thud, thud! Baek Sa thrust with desperation, completely overtaken by desire—so much so that it was impossible to picture the calm, composed version of him that usually existed. Just watching the way his body moved, rough and unrelenting, was enough to make Ha-gyeom’s entire length throb with blood to the tip.

As Baek Sa panted and moved more erratically, he suddenly pulled Ha-gyeom into a crushing embrace, like he might shatter them both.

“Haa…!”

Finally, Baek Sa collapsed his upper body over Ha-gyeom’s and let out a ragged, almost dying moan against his ear. He drove forward like he might shatter Ha-gyeom’s spread thighs—and at last, finally, he came. Even while releasing, he kept thrusting relentlessly into that impossibly deep spot, fully savoring the pleasure.

Even in the moment of climax, his thrusts didn’t stop. Ha-gyeom wrapped his arms around Baek Sa’s neck, moaning through trembling breath.

“Haa, I’m gonna—nngh…!”

Right after Baek Sa, Ha-gyeom’s own penis—pressed against his belly without a single touch—twitched and released, spilling thick semen across his already-glossy chest. Baek Sa, finally letting go of Ha-gyeom’s restrained legs, looked down at the mess and moved his hips with practiced ease.

“Mmgh… ngh…”

Ha-gyeom grasped himself and squeezed out the last drop, overwhelmed by how terrifyingly good it felt—how impossibly full. The sensation of semen spreading warmly through his stomach, mixed with the steady, leaking rhythm from the overstretched opening, was electric.

Still rubbing his now-spent penis, he eventually slipped his hand between their bodies to touch where they remained joined. Everything was soaked, already swollen. The pleasure refused to fade. Fingers gliding over his slick perineum, anus, and Baek Sa’s penis, Ha-gyeom finally looked up—eyes dazed and heavy.

“……”

Even after everything, Baek Sa’s eyes showed no sign that his desire had subsided. Ha-gyeom already knew what it meant to be so aroused it almost felt like resentment—he had shared his body with Baek Sa enough times to understand it all too well.

With a hand trembling beyond control, he pulled Baek Sa in for a kiss. Baek Sa responded willingly, and Ha-gyeom licked and sucked at his lips and tongue with an almost brutal intensity. He even bit down on the warm flesh in his mouth—but Baek Sa didn’t resist. He gave him everything.

Only then, with a short groan, did Baek Sa finally withdraw his penis.

Pop. With that sound, he pulled out. Ha-gyeom instinctively reached down, pressing fingers into his now-empty entrance. He’d thought it had been ruined—stretched too wide—but the way the muscles clenched around his fingers showed it still held strength. Imagining what it must have felt like for Baek Sa while moving inside him made a dull ache stir deep in his belly.

Baek Sa, gripping his wide-spread thighs, watched the scene intently. His already re-hardened penis visibly twitched. The sheets, which had slipped away during their movements, were now dragged back up to his waist—but even before Ha-gyeom could pull his fingers free, Baek Sa pressed the thick head of his penis against his entrance once again.

“Hhngh, ngh…”

Without any cleanup, the next round of penetration began. There was no way to refuse. Ha-gyeom drew in a deep breath, feeling just how tightly his own fingers had stretched him before Baek Sa even entered.

---

“Haa… Baek Sa… please, just stop now…”

Ha-gyeom released the handful of Baek Sa’s hair he’d been gripping under the sheets and murmured in protest. He’d already climaxed at least five times—and with Baek Sa still going down on him like this, the next one felt impossibly far away.

“Do you really want me to stop?”

“Yeah, really… that’s enough…”

His sore anus was one thing, but it wasn’t normal for his penis to hurt this much. Licked, sucked, even nibbled on—Baek Sa hadn’t stopped at just that. From head to toe, he’d kissed and sucked every inch of him, and still didn’t seem ready to quit. As if searching for another spot to taste, Baek Sa showed no sign of letting up.

He couldn’t possibly head out for training with his body this drained—he didn’t even have the strength to lift a hand. Only after he reluctantly pulled the sheet away did Baek Sa finally release his penis from his mouth and smoothly slide up to wrap Ha-gyeom in his arms.

With their lower bodies locking together like a bolt and nut, Ha-gyeom felt as if they had become one. It was just their penises rubbing against each other, yet the sensation was dizzying enough to make him exhale sharply and avert his gaze.

Dawn had already broken. Assembly wasn’t until 10 a.m., so there was still some time left, but as training drew nearer, a creeping tension began to rise within him.

Even if it was just training for now, he had no clear idea what awaited in that unknown territory. He’d never been through it before, and all he really knew was that it was dangerous—a guess based solely on what he’d observed from Ah-rang’s condition.

Maybe Baek Sa noticed the shadow that had fallen over his face. Instead of looking at him directly, Ha-gyeom had fixed his gaze on the clock—prompting Baek Sa to gently lift his chin and make him meet his eyes.

Smooch, smooch…

After the kiss, Baek Sa’s gaze had grown noticeably more serious. With his mind finally clearing, Ha-gyeom began to replay the night’s events like a film, flashing through his thoughts.

His face flushed so deeply it felt like it might explode. On that bed, Baek Sa had been every bit the powerful Esper he was known to be. There had always been rumors that Espers had incredible stamina, but Ha-gyeom had never had a chance to confirm it—until now. Even now, seeing Baek Sa’s taut, swollen muscles after such an ordeal, panting and having climaxed multiple times, Ha-gyeom still couldn’t quite believe it. But then he looked at his own body, marked and glowing red from head to toe, and it all somehow made sense.

And yet, what truly overwhelmed him was how his affection had only deepened. As he tried to suppress the nervous tension building inside him, Ha-gyeom gently reached out to stroke Baek Sa’s chin—who still hadn’t taken his eyes off him.

“Did you like it?”

As he asked, he felt—for just a moment—like an adult. Like he was standing on equal footing with Baek Sa. He had completely forgotten about guiding, and what remained between them was the shared certainty that, as two grown men, they had brought each other to satisfaction.

“Of course I did.”

Baek Sa answered softly, so gently it stood in stark contrast to the intensity of the night before, and a faint smile touched his lips. When he glanced at the wide windows, where morning light was beginning to seep in, it was almost a shame to see that smile fade.

“‘Liked it’ isn’t enough to describe it.”

Ha-gyeom understood what those suddenly furrowed brows and deep, well-like eyes meant. When Baek Sa leaned in to bury his lips near Ha-gyeom’s ear and pressed him down with quiet intensity, his whisper was private, aching.

“How… am I supposed to let you go, like this?”
