Chapter 1

“Rian, who does your body belong to?”

Even without any conscious brainwashing, the answer slipped naturally from Rian’s lips as though it were the most obvious truth in the world.

“Hyung, I’m only yours.”

“Good boy, my pretty thing,” Yu-gyeom murmured with velvety approval. “I’ll praise you today, too.”

At those words, Rian’s legs parted as a matter of course, fully exposing his wanton lower half. Yu-gyeom crawled between Rian’s thighs like a dog. Then, with painstaking care, his tongue licked across Rian’s groin.

“My sweet, Rian.”

Even if someone brought him the sweetest fruit in the world, could it ever compare to the lovely Rian he had raised with such devotion? A fragrance far richer and heavier than nectar welling from ripe fruit tantalized Yu-gyeom’s appetite.

Yu-gyeom thrust his tongue into Rian’s red hole, savoring every drop of the taste.

That alone left him feeling sated to the point of bursting.

* * *

Thirty-year-old Yu-gyeom had a habit—taking custody of twenty-one-year-old Rian’s lower half. It had not always been that way. In the past, simply pitying the orphaned child, Yu-gyeom had done nothing more than wash, feed, and tuck the boy into bed. But when Rian abruptly manifested as an Omega around the time of his high school graduation, it gave Yu-gyeom the perfect excuse to act on the desire he had harbored for so long.

Gaining admission to the university he wanted and celebrating his high school graduation with a light heart had all gone smoothly. But that very night, Kwon Rian awakened as an Omega, suffering the agony of the smooth skin beneath his cock splitting open. Rian was entirely helpless before the searing pain and bodily transformation he was experiencing for the very first time.

Yu-gyeom would never forget the sight of Kwon Rian crawling toward him at dawn, weeping inconsolably. Creeping forward like an abandoned puppy, Rian had stood in the faint dawn light, pulled down his trousers, and revealed what lay beneath—a flushed, glistening set of female genitalia. In other words, a pussy.

“Hyung… hic, hyung. What grew on me down here?”

When Rian lay beside him, spreading his thighs wide to reveal the pussy beading with slick arousal without holding back a single thing, Yu-gyeom felt his chest swell to the point where his heart seemed ready to burst.

It was an ecstasy he had not experienced since the thrill of first laying eyes on nine-year-old Rian.

Ah, is this what a parent feels when raising a child?

No, no—this was closer to the thrill of tending a tree for over ten years, anxiously waiting day and night for it to bear fruit, only to finally witness a single luscious prize form on the branch. Just imagining splitting that fruit open and slurping it down made saliva pool beneath Yu-gyeom’s tongue as he gazed down at Rian’s pussy.

Furthermore, the freshly awakened Kwon Rian radiated a continuous stream of thick, cloying pheromones that poured from him like a waterfall. That night, as if struck by lightning in his sleep, Yu-gyeom had been forced to endure a downpour of Rian’s pheromones.

Would none of it have happened that night if he had been a Beta? Yu-gyeom occasionally entertained such futile hypotheses, but even when Rian was a Beta, had Yu-gyeom not waited day and night for the boy to become an adult? That the two of them would end up rolling in bed together was an inescapable certainty. Yu-gyeom lived with the conviction that they were bound by fate either way.

Even before then, Rian’s secondary gender had not mattered to Yu-gyeom, but the moment Rian truly manifested as an Omega, Yu-gyeom realized God was on his side. Yu-gyeom had been an Alpha since birth, destined to bond with an Omega sooner or later. There was a limit to how long he could hold out on suppressants.

And in the midst of that, the Rian he cherished so tenderly had manifested as an Omega. If God was not on his side, what else could it be?

That was when it began—Yu-gyeom taking strict, methodical control of Rian’s lower half.

Having lost both parents overnight, nine-year-old Rian had no choice but to depend entirely on Yu-gyeom, who had been living under his parents’ roof. Because Rian had always followed Yu-gyeom so faithfully, it did not take long for the boy to weave himself into Yu-gyeom’s life.

Eating, sleeping, dressing, and bathing—all of it fell under Yu-gyeom’s care. Having lost his own parents long ago and survived on cold glares while bouncing between relatives’ homes, Yu-gyeom had quickly grown fond of young Rian, who obeyed him so sweetly.

At first, driven by a desperate desire for stability, he had only acted to get on the good side of Rian’s parents, but he soon fell for the innocent, adorable child as well. Being with Rian gave him a sense of safety and a peaceful warmth he had never known before. That stability also stemmed from how reliably Rian remained within the palm of Yu-gyeom’s hand, never straying. To Yu-gyeom, Kwon Rian was an existence free of volatile variables. Naturally, therefore, Rian’s entire world was made up of Yu-gyeom alone.

Yu-gyeom kept tight reins on Rian. With deep affection and the attentiveness one might show to blood kin, he dedicated himself to raising the boy.

In that manner, Rian’s world soon became synonymous with Yu-gyeom. Without resting for a single minute or second, Yu-gyeom devoted everything he had to Rian. How could that not be love?

Without even realizing he was gradually losing his sanity over the boy named Kwon Rian, Yu-gyeom cared for someone not tied to him by a single drop of blood, under the very same roof.

* * *

Yu-gyeom returned home after an exhausting itinerary. He wanted to lie down and rest his weary body, but he never neglected the duty that awaited him. In fact, merely thinking of that task made his heart swell like a balloon ready to burst with anticipation.

The quiet dawn air hung heavy throughout the house. Careful not to wake Rian, Yu-gyeom set down his suitcase. He washed his hands thoroughly, filled a basin with warm water, and checked the temperature. Then, gathering cleanser and a soft towel, he made his way up to the second floor.

Suddenly, he remembered how cute Rian had been when the boy video-called him from his business trip, begging Yu-gyeom to watch him wash his lower half. Thinking of naive Rian, unable even to clean his own pussy properly, Yu-gyeom could only find him ridiculously endearing.

“L-like this? Hyung, this feels weird… It’s, it’s all slippery.”

“Then try slipping a finger in—yes, right there…” Yu-gyeom coaxed through the speaker. “Can you put it inside the hole, Rian?”

“Ngh…” Rian whimpered, his voice trembling over the screen. “T-this isn’t washing.”

“No, you have to scour the inside of the hole clean, just like I always do for you,” Yu-gyeom instructed steadily. “That’s it. Good boy, Rian.”

Because Yu-gyeom had washed Rian’s genitals ever since his manifestation, the boy’s body still felt foreign to himself. Sliding one finger and then another into the hole, rinsing the inside while rubbing his cleft, Rian had ultimately ended up masturbating right in the middle of their video call.

“Haah, hy-hyung, I… I want you to fuck me…”

“When I get home, I’ll give you a reward for doing so well on your own, Rian,” Yu-gyeom promised in a husky whisper. “I’ll suck you and fuck you. So wait like a good boy, all right?”

“Hnng… Yes, yes, I miss you…” Rian pleaded, overcome with wanton longing. “Hyung, l-lick my p-p…”

Yu-gyeom’s voice came through the receiver, stern and unyielding. “You have to speak clearly. I told you I can’t understand when you mumble, Rian.”

“L-lick my, my pussy with your soft tongue, hyung…” Rian sobbed out, flushed with overwhelming shame.

Haa. Watching the boy stir his insides with that crimson, flushed face, how desperately Yu-gyeom had wanted to race straight back home.

Was it really all right to leave home so often when Rian couldn’t do a single thing without him? Perhaps he ought to transfer to another department. Yet he was already well-established in his current position, with high rank and excellent benefits. Of course, even if he moved to another company, his capabilities guaranteed he would be treated exceptionally well.

On the other hand, whenever Yu-gyeom left home on frequent business trips, seeing Rian cling to him and cry about how much he missed him felt downright intoxicating. After all, outside of those trips, opportunities to relish Rian’s body across a screen were rare.

A faint smile lingered on Yu-gyeom’s lips as he slowly climbed the stairs, lit only by indirect lighting. Steam curled gently from the basin in his hands. At the thought of seeing Rian, a hum slipped unbidden from his throat.

Being kept from seeing Rian for two whole days—it was simply too cruel. Standing before Rian’s bedroom door, Yu-gyeom turned the knob without hesitation and pushed it open. Knocking was omitted as a matter of course.

“Ah, this boy…”

A soft arc curved Yu-gyeom’s lips. At the sight of Rian asleep in bed, a laugh escaped him unbidden. His chest swelled to bursting.

Did he masturbate again after I taught him just once? Inside the closed room, the thick scent of Rian’s pheromones rolled in heavy waves. That dense fragrance stirred Yu-gyeom’s loins, making his front swell taut against his trousers.

Stepping closer to the bed, he saw Rian clearly in the dim light of dawn. Wearing only an oversized dress shirt without even underwear, the boy’s demurely closed thighs came into view.

Saliva pooled thickly in Yu-gyeom’s mouth, and he licked his lips. Bending forward, he checked Rian’s hips. Peeking out from between hairless, porcelain-smooth thighs, the plump pussy was swollen and flushed crimson.

Just how much did he rub it? What if he gets an infection?

He had probably comforted himself in his longing to see his brother. Lowering his face toward the pathetic yet adorable boy’s crotch, Yu-gyeom slid his tongue out.

Then, with a wet slurp, he licked a long stripe upward from the pussy—where the slick arousal had not yet dried—all the way to the back hole. As the sweet scent of pheromones washed over his nose, an almost dizzying euphoria surged through him.

“Ngh…”
