Yeon Yiseo’s insides clenched tightly around Alexander’s cock, trapping it as if to prevent him from pulling out—only to suddenly relax, accepting the thick shaft with a yielding surrender. The slick, sticky inner walls clung to the shaft, kneading it, and Alexander exhaled in a way that betrayed his excitement.
His thick cock relentlessly pounded the deepest parts of Yiseo’s belly, like he was hammering and softening the flesh from within. The heavy, throbbing shaft shifted its trajectory all at once.
“Ah! Hhn, haah, uh. Mm! Aaah! Agh, ahk!”
Yiseo shook his head violently. The overwhelming pleasure bordered on pain—it was like tiny needles pricking at his skin.
But there was no escaping it. Yiseo tried to push himself upright, rising into a kneeling position. He planted his legs, attempting to pull away from him, but Alexander gripped his waist firmly, as if to say he wouldn’t allow it.
“No, wait, this is—hnn, too—ah! Hnn……! Agh! Ahhk! Aah!”
His words came out in broken, gasping fragments with each harsh thrust. Alexander gripped Yiseo’s waist, pulling him down as he thrust upward simultaneously. Their joined bodies slammed together without a sliver of space, over and over, each collision resounding with wet, smacking noises.
At some point, Alexander spilled inside him again. It was his second climax, but the amount didn’t seem to lessen—if anything, it felt even heavier than the first. The sensation of being filled to the brim nearly made Yiseo gag.
“……Ugh, uhhuhk…… haah, hnn. ……Uh, uhk……”
Yiseo’s half-hard cock drooled a small trickle of fluid. As the warmth of another flood of semen filled him, Yiseo looked down at Alexander with dazed eyes. His expression, twisted in pleasure, was blatantly obscene. That raw, undisguised lust stirred something delirious inside Yiseo.
“……Haa.”
He collapsed, the upper body he’d barely held upright now draping across Alexander. He couldn’t hold on any longer. His lips brushed Alexander’s hot skin. Smooth and warm, he moved his lips slowly across it—not for any reason, just because he wanted to.
His limbs turned heavy, and his eyes drifted shut. He was about to fall asleep without realizing it. He figured Alexander would probably be satisfied by now and fall asleep too. But that was only a naive guess—from someone who still didn’t know much as a beta.
“……Huh? Ah, ahk!”
He felt his body shift slightly—Alexander had wrapped his arms around Yiseo’s upper body and turned them, laying him down on the bed again. The cock inside him never left.
As Yiseo stupidly wondered no way, the thick shaft inside him stirred to life again.
“Ugh! ……Ah, uh, hnn…… mmh. Uhk……!”
With the resumed thrusts, the semen that filled him sloshed around inside.
“I can’t do this anymore, I can’t, ngh, hnn. ……Mmh, mm…… hhaa.”
Yiseo tried to push him away weakly, voicing a feeble refusal—but Alexander silenced him with a kiss. Then, after pulling back briefly, he pressed soft kisses to Yiseo’s cheek, the corners of his eyes, and his forehead in turn. Those tender, fleeting kisses melted his resolve in an instant.
Yiseo parted his legs slightly—just a little—and Alexander seemed to understand, leaning in and sealing their lips again.
A hot tongue slipped between his parted lips. Responding to the slow, deliberate movements, Yiseo opened up, their tongues brushing and pulling back with damp, squishy sounds. Like two people gently nibbling at soft pudding, they took turns sucking and biting each other’s tongues. The gentle kisses were enough to stoke the lingering embers in his body.
When Alexander resumed moving, his pace was languid—so slow that it almost didn’t seem like he was moving at all. But precisely because of that, Yiseo became painfully aware of every detail—every shape and contour of Alexander’s cock. He could even feel the raised veins pressing along his insides.
“Mmh, ……ahk…… mmm, nghh.”
His slackened, melted inner walls molded themselves around the shape of that cock like well-kneaded dough. With every unhurried thrust, moans spilled from Yiseo’s lips without effort. Just moments ago, he’d hated the rough pace, and yet now, he was desperate for more.
His legs, weak and spread, trembled on either side, unable to support him. His insides quivered and clung to Alexander’s cock like they were begging. His hole contracted repeatedly, fluttering open and closed.
But no matter how much he begged, Alexander didn’t speed up. He kept it slow, so agonizingly slow it drove Yiseo mad.
Every time he bottomed out, Yiseo felt full to the brim—only to feel empty the moment Alexander pulled back out. With every slide of hot flesh through the tight hole, a bit of semen leaked out, squelching audibly and filling the quiet space with wet, obscene sounds.
Alexander drew back almost to the crown before plunging in deep again, over and over. His cock was so long and thick that Yiseo couldn’t help but moan, his voice trembling. Even this slow pace was enough to steadily build his arousal again.
“Uhk, hnnn, hnn, hff, aaah, ngh…….”
Yiseo’s cock wasn’t even hard, only releasing a few weak drops of clear fluid. His whole body trembled like ripples in water. The muscles in his abdomen tensed sharply, clamping down tightly on the cock filling him.
“……Ugh.”
Alexander let out a low groan. His eyes narrowed faintly. Yiseo’s gaze lingered on those eyes, glazed with pleasure.
Panting shallowly, Yiseo reached for him, and Alexander pulled him into his arms without hesitation. Their two heated bodies pressed together once again, not a single space left between them. Their sweat-slick skin slid against each other—but even that felt good. It felt like they were melting together into one. Their hearts pounded in sync, like they’d merged into a single beat.
“Mmfh, hnn, uhk, ah! Ah! Aaaah!”
Then, suddenly, Alexander’s cock began slamming into him—fast and hard. Yiseo’s entire body shook from the impact. Each time their flesh collided, loud slapping noises filled the room like he was being spanked.
“Ah! Uh! Uhk! Ngh, ah! Aahk!”
“Haa. Hoo. ……Hmf.”
Had he not been holding onto Alexander, he would’ve been shoved up toward the head of the bed. The entrance stayed slick thanks to the semen acting as a natural lubricant.
The deepest part of Yiseo’s insides, where Alexander’s cock pounded mercilessly, had grown soft and pliable. Alexander seemed determined to push even deeper.
“Ahk! Aah, ahk. ……Ah! This is—weird, ah, hnngh!”
It felt like there was nowhere left to go—and then suddenly, something tore.
Snap.
Yiseo’s eyes flew open as his entire body stiffened. The inner walls clenched tightly around the cock that had just broken through.
Alexander’s cock was pushing past a barrier Yiseo had thought would never open, parting it forcefully with the head. A deep, dull ache radiated through his body.
Yiseo trembled violently—but it wasn’t just from pain. The narrow passage spasmed as if to repel the intruder, the motions reminiscent of a mouth trying to chew something. It only served to stimulate Alexander even more.
“……Tch.”
Alexander let out a strained breath and pulled Yiseo tighter into his arms.
But the real surprise came next. The cock buried inside him began to swell. It wasn’t an illusion—he could feel it pressing outward, like it was physically pushing against his skin from the inside.
What is this? What the hell is this…?
Yiseo’s eyes flew wide in alarm.
Knotting.
“CEO, please—wait, this is…… agh. Ugh…… ngh, ughk.”
It was one of the core traits he’d learned about Alphas when studying trait-bearers. Knotting. A biological response meant to increase the chances of pregnancy. Though it could be done consciously, it typically happened involuntarily.
The defining feature? The knot—swelling to the size of a grown adult’s fist.
Could his guts really handle something that big inside?
Yiseo wasn’t an Omega. He was a Beta.
A sharp fear gripped him. He was genuinely terrified that his insides might tear. And yes, it hurt—a lot.
“Aah, it hurts, it hurts……. Ngh, ah, what do I—ugh, hnn, I’m scared…….”
Kicking his legs in panic, Yiseo scratched down Alexander’s back. The pain had him on the verge of sobbing.
But Alexander didn’t loosen his embrace. He didn’t even groan despite how much it must’ve hurt.
He only pressed gentle kisses to Yiseo’s temple and forehead.
“Good boy……. You’re doing so well.”
His voice was low and hoarse, with an odd metallic edge. Like he was soothing a child, Alexander kissed him again and again.
That made Yiseo’s strength melt away.
Maybe his body was getting used to it—because the deep, aching pain started to ease. Alexander’s cock had likely finished swelling by now.
How long does this last again?
Yiseo tried to recall what he’d learned in school. Was it a few minutes? Tens of minutes? He couldn’t quite remember.
As Alexander’s lips repeatedly brushed against the corners of his eyes and cheeks, as if to reassure him, Yiseo eventually fell asleep.
Or perhaps fainted was more accurate.
For the first time, he realized how truly wonderful it was to fall asleep wrapped in someone else’s warm body heat.
Yiseo had never felt this good, this satisfied, in his life.
