Cha Se-jin buried his lips in the crook of Eun-won’s neck, peppering it with kisses until Eun-won’s breathing steadied, then finally lifted his head to look down at Eun-won’s tear-streaked face. The hair slightly damp with sweat and the eyelashes wet with tears were so beautiful that when he kissed him, Eun-won smiled again.
“Why do you keep smiling? So prettily.”
Pressing a soft kiss onto those smiling lips, Cha Se-jin released more pheromones to help Eun-won’s body relax. As if that felt good, he could feel Eun-won’s pheromones growing thicker.
“I feel… so good.”
“I’ll make you feel even better.”
Cha Se-jin’s large hand gently gripped and spread Eun-won’s soft inner thighs, burying his face between them. Startled, Eun-won tried to stop him, but his tongue was already licking the area beneath his genitals.
“Ah…. Hng…!”
The hot, wet tip of the tongue rubbed down from the base of Eun-won’s penis along the perineum. Since he had ejaculated not long ago, all his sensations were extremely sensitive; every time the tongue obsessively licked and rolled over his skin, Eun-won’s hips jerked violently.
Amused by the reaction, Cha Se-jin pressed the tip of his tongue against the plump perineum before opening his mouth to suck it in. Each time he did, the wet hole fluttered, and lubrication flowed freely. Watching the excessively erotic hole that closed and opened, leaking lubrication, Cha Se-jin flicked his tongue over the opening.
“Ha-eut…!”
Eun-won’s waist twisted. As his legs tried to close, Cha Se-jin spread his thighs again, gripping his pelvis to keep him still as he buried his face and pushed his tongue inside the hole.
He took the red, concave hole entirely into his mouth, pushing his tongue deep inside to lick the interior thoroughly, eliciting a piercing cry. Hearing that sweet, tearful sound, Cha Se-jin felt his penis harden again. He poked deeper with his tongue, sucking and swallowing the overflowing lubrication.
“Ah, nng…! There, hng, there… ah… it’s strange, really, it feels so strange….”
“Mm, does it feel strange?”
“Hng…!”
It wasn’t the first time Cha Se-jin had put his tongue inside, but this pleasure felt fresh every time, delivering an overwhelming sense of ecstasy. And the feeling of him speaking while his lips were pressed against the opening was too explicit. It was a stimulation that felt almost excessive. But he didn’t hate it.
He felt the tongue enter and exit his body. Every time it rubbed the inside, it felt as if his entire body were being licked. His stomach churned, and his body burned. Even as pheromones poured out of him, there was nothing he could do.
“Darling, does it feel good?”
When he spoke again with his tongue still inside, his lips moved, tickling the surrounding area. Eun-won’s hand pressed down on Cha Se-jin’s head. The hand that had descended to push him away was now only fueling Cha Se-jin’s excitement.
Cha Se-jin spread Eun-won’s legs wider, fixing them in place, and pushed his tongue deeper into the hole, rolling it around. The sweet, concentrated milky scent of Eun-won’s pheromones and the lubrication tasted sweeter and more delicious the more he inhaled and tasted them. He had reached a point where he preferred this sweetness over any other flavor. He loved it so much that he would be willing to live solely on this lubrication if he had to.
After spending a long time poking the inside with a pointed tongue, Cha Se-jin finally withdrew it only after Eun-won reached a peak and ejaculated. Wiping the lubrication from the corners of his mouth and licking the fluid off his hand, Cha Se-jin lowered his head again to take Eun-won’s glans into his mouth. Simultaneously, he gently pushed two fingers into the interior he had loosened with his tongue, softly relaxing the deeper parts.
“Ah, hng…! Ah, ah… nng…!”
Being stimulated in two places at once left him with no way to endure it. Eun-won groaned, clutching the blanket tightly. Another wave of ejaculation washed over him. Every time the fingers, which reached depths the tongue could not, gently scraped a certain spot without any roughness, his vision flashed white.
When a third finger joined the others and was pushed completely inside, Eun-won ejaculated into Cha Se-jin’s mouth.
Only after drinking every drop of the semen flowing into his mouth did Cha Se-jin release his genitals. Licking his wet lips as if it were delicious, his face looked thoroughly pleased.
“Darling. Is it because I love you? Why is everything that comes out of your body so sweet? I think you’ve become even sweeter than before. It’s because you love me, right? I love you too.”
Having said such tingling words nonchalantly, Cha Se-jin kissed Eun-won’s flushed pink cheeks deeply and aligned his hardened penis with the thoroughly loosened hole. He teased him, poking the tip of the glans into the lubrication, and then pushed in with force, sliding completely inside.
“Ah…!”
“…Ngh, ah….”
As he slowly moved his hips, the thick, long penis filled Eun-won’s interior tightly. Eun-won felt their bodies lock together completely, rubbing his tongue against Cha Se-jin’s as they kissed. The feeling of becoming one body without a single gap was wonderful.
Perhaps it was because he knew Cha Se-jin loved him. Just as Cha Se-jin had said, all these sensations felt even better than before. Eun-won let out a long moan as the penis hit the spot he felt the most in the depths of his body.
“Haa, hng…! Nng…! Director… ah, there, right there… nng, keep hitting there….”
“Mm, just here.”
As he slammed into the spot where even a graze caused an unbearable moan, Eun-won’s mind quickly became a mess. Due to the excessive stimulation, Eun-won couldn’t even breathe properly and cried out. Every time the inner walls were scraped, lubrication dripped from the junction, soaking the sheets. Cha Se-jin pulled Eun-won’s legs closer over his shoulders and thrust upward even faster.
“Nng……. I think… I’m going to… do it again…. Ah, ha-eut…!”
“Ugh, do it, huu…. You can do it…. Do you like it here?”
“I like it… hng, I love it…. So, nng, much….”
The tip of the penis rubbed and crushed the protruding part of the inner wall. Keeping his penis deep inside without pulling out, Cha Se-jin moved his hips slowly, rubbing the spot Eun-won felt the most. Then, the moment he thrust with force, making a loud thud, clear fluid burst from the tip of Eun-won’s penis.
“Ha-eut…!”
Eun-won’s hips jerked violently. His flat stomach, which clearly showed the outline of the penis, rose and fell, and he shed tears, unable to even open his eyes from the pleasure. Even as Eun-won felt that, Cha Se-jin continued to scrape the inside with his penis. An even greater pleasure was layered atop the intense ecstasy. Due to the continuous, unceasing pleasure, fluid flowed from the tip of Eun-won’s penis once more.
Cha Se-jin, who didn’t take his eyes off Eun-won—who seemed to be experiencing a prolonged peak rather than just the afterglow of ejaculation—thrust inside one more time and caught his tongue in Eun-won’s mouth. At that moment, Eun-won’s pheromones erupted.
As if everything had been flung wide open, a sweet scent of milk and sugar continued to gush from deep within Eun-won’s body. That sweet scent, which opened every sense in the body, flowed into Cha Se-jin through his breath. His mind wasn’t just a mess; it felt as if it had been completely shattered.
“Ngh…!”
Suddenly, his entire body burned as if he had entered a Rut. His breath became uncontrollably hot, and his vision blurred. Simultaneously, the tip of the penis deep inside Eun-won swelled firmly, gripping the narrow interior without a single gap.
It was knotting.
Cha Se-jin’s penis was now pressed against Eun-won’s cervix. Their bodies were locked so tightly that he couldn’t pull out. If he tried to force it, the interior could be seriously injured, so he couldn’t move at all.
“Ah… hng, Director… it hurts…. Hng, my stomach is too full……. Why suddenly….”
“I, ah…. I think I got so excited that I knotted.”
“…Knotting?”
Though he had never experienced it, Eun-won knew what knotting was. It was when an Alpha’s penis swelled inside the body during a Rut or extreme excitement. He also knew that for it to release, a large amount of ejaculation was necessary, and that knotting usually led to pregnancy.
Pregnancy.
He had never properly thought about it. Even while getting married, he hadn’t seriously considered it. But strangely, the thought that he didn’t dislike it crossed his mind first. Although he knew it wasn’t something to decide impulsively, the look in Cha Se-jin’s eyes was so steadfast that for a brief moment, he thought it might be okay within that steadfastness.
“Huu…. I’m sorry, it hurts. I must have truly lost my mind because I like you so much.”
Cha Se-jin was equally flustered. In all his life, he had never knotted like this. He hadn’t even knotted anyone else during his Ruts. People talked about reproduction being an Alpha’s instinct, but Cha Se-jin had never felt such an impulse or instinct.
But today was different. Of course, Eun-won’s pheromones had poured out in abundance, but to be this uncontrollably excited…. With the swollen tip of his penis pressed against Eun-won’s cervix, Cha Se-jin kissed Eun-won’s cheeks, lips, and wet eyes in turn, as if to soothe him.
“It’s okay, breathe slowly and just… ngh, relax a little. Slowly.”
To calm the bewildered Eun-won, Cha Se-jin released more pheromones. He could feel Eun-won’s body relax further in response to the pheromones. To ensure he wasn’t scared, Cha Se-jin kissed his eyes and cheeks before meeting his wet breath. Their tongues mingled softly, neither knowing who started first.
“…Nng….”
As the two thick pheromones tangled together and filled the room, Eun-won’s tense interior softened slightly, willingly swallowing Cha Se-jin’s massive volume. Not missing the opportunity, Cha Se-jin moved his hips slowly while still knotted.
“Ah… hng, nng….”
“Just a little, ah… if you hold on just a little….”
“Director… hng, Director…. Too, nng…!”
As the wet inner walls rubbed against the penis and the expanded glans lightly pushed against Eun-won’s narrow cervix, Eun-won cried out as if he were losing his breath, desperately clinging to Cha Se-jin’s neck.
Further excited by that innocent clinging, Cha Se-jin embraced Eun-won’s entire body and moved his hips deeper. As the swollen glans locked tightly against the cervix, the urge to ejaculate surged. Cha Se-jin captured the lips of the weeping Eun-won, and the moment he forced the tip of his penis tightly into the narrow gap, a massive amount of hot semen poured into the uterus.
“Ha-eut! Ah, nng… nng…!”
“…Ngh, ah…!”
Eun-won’s hips jerked several times as he received Cha Se-jin’s semen pouring deep inside him. Only after pouring thick semen into Eun-won for a long time did the swollen tip of the penis subside. By then, Eun-won, who had been trembling, unable to support himself due to the excessive sensation, drifted into unconsciousness.
Slowly withdrawing his penis as the knot released, Cha Se-jin watched the semen and lubrication flowing from the hole, then pulled the fainting, sleeping Eun-won into his arms. Even in his sleep, even without any strength left, Eun-won burrowed deeper, knowing he was in Cha Se-jin’s embrace, which was incredibly lovely.
“I love you, sleep well.”
Kissing Eun-won’s damp forehead and cheeks, Cha Se-jin whispered with his lips against his ear. Eun-won was already asleep and couldn’t hear him, but Cha Se-jin hoped that if some part of his subconscious heard these words, they would lead him to a beautiful dream.
