Perverted Little Sister and Dark Cat Big Sister's Sister Rice Bowl Service♥ (1)

"Hngh…♥ Haaah…♥"

Rui-lin lay unconscious, her belly swollen like a pregnant woman's from the ultra-concentrated semen that had flooded her womb. She didn't even seem to notice how distended she had become.

"Phew… Thank goodness. Ah!"

While Si-yoon had been focused on Rui-lin's slave evolution, he suddenly remembered Chae-ryeong, who had been left with the vibrator still buzzing at full speed.

"Hngh… Haaah…♥"

—Click— The piercing-shaped vibrator clipped to her nipples had run out of power and stopped vibrating. The rod-shaped vibrator between her legs had also slowed to a weak hum.

Si-yoon unfastened the belts binding Chae-ryeong's arms and legs and removed the blindfold that had kept her in darkness.

"Your wrists and ankles are all red and swollen. Did I leave them on too long?"

Chae-ryeong breathed slowly, looking exhausted. Si-yoon's voice carried a hint of guilt.

"Nyaa…♥ If it helped Master… then I'm happy…♥ And being tied up so tightly while buzzing like that… felt really good…♥"

Chae-ryeong licked Si-yoon's face reassuringly with her tongue. He gently patted her butt in return, praising her.

"By the way… Rui-lin seems to have submitted to Master as well…♥ She has such a blissful expression…♥ Nyaaat…♥"

Chae-ryeong stared enviously, finger in her mouth, at the sight of Rui-lin completely drenched in overflowing semen.

"If I'd given her even a little opening… it wouldn't have been this easy. Last time she had no strength to move, but not this time."

Rui-lin's ability, "Bombification," was a destructive power that could create bombs with the slightest movement. The condition was simple—mere contact with her bare hands. Knowing this, Si-yoon had kept her wrists and ankles locked in heavy, restrictive handcuffs to completely suppress any motion. Having enslaved many powerful females by now, he had taken extra precautions with Rui-lin because of how dangerous her ability was.

"I can take the handcuffs off now."

—Click!—

Si-yoon inserted the key into the heavy cuffs binding Rui-lin's wrists and ankles. With a metallic snap, he removed all four restraints.

"Even I was getting tired of how heavy these were."

Once the cuffs were gone, the absorption of semen began in earnest. The thick fluid filling Rui-lin's lower belly slowly receded, and the sticky white mess coating her entire body gradually vanished.

"Nyaaah…♥ That feeling of being reborn… I'll never forget it…♥"

Watching Rui-lin's evolution reminded Chae-ryeong of her own transformation, just as Do-hwa and Ji-woo had once watched hers.

"Hngh…♥ Haah…♥"

Sweet moans escaped Rui-lin's lips as she absorbed the semen and underwent her evolution. It was proof that the pleasure and ecstasy of transformation were being etched into her brain—and a sign that physical changes would soon follow.

The once-swollen belly flattened out completely. The skin that had been stained with white fluid now looked smooth and dry. The Slave Brand's evolution had truly begun.

"Haaah…♥♥"

Her body, which had been so small and frail that it was hard to believe she was twenty-five, began to fill out. Her slender frame gained curves as her skeleton subtly shifted. Even her once-dry, unkempt hair and skin gained a healthy sheen.

The most dramatic changes were to her breasts and hips. They swelled larger and heavier, perfectly matching her newly voluptuous figure.

"Her breasts… they're getting so big…♥ At this rate, they'll be about the same as Ji-woo's…♥"

Ji-woo ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠had been slightly taller than Rui-lin but had also started with A-cup breasts. After becoming a slave, she had developed a sensual, explosive body. Now Rui-lin was undergoing the same glamorous transformation.

The changes were so extensive that her overall proportions had shifted more dramatically than any previous slave.

"Ufufu…♥"

Once the physical transformation ended, a provocative laugh escaped Rui-lin's lips. She no longer looked like the timid, petite girl she had been. Her appearance, voice, and aura had all matured.

She didn't look older than her actual age of twenty-five, but she now appeared to be in the same age range as Do-hwa or Ji-woo.

"Ufufufufu…♥"

A black halo shaped like a winged heart—the mark of corruption—floated above her head. Beneath it stood Rui-lin, now visibly more mature, smiling at her master.

"Perverted little sister Rui-lin… has been reborn as the great master and big brother's… Dominator's 'Corrupted Slave'♥"

She knelt and bowed her head to Si-yoon, declaring her new existence.

"How do I look, Oppa? My newly reborn body…♥"

"Body Transformation? Glamour Mode?"

The system responded immediately with a clear explanation, as it always did when Si-yoon was confused.

"So… she can switch back to her original body type too?"

According to the system, Rui-lin's Slave Skill let her toggle between her original slender form and her current glamorous one. That meant Si-yoon could enjoy two completely different versions of her.

"Rui-lin. Try switching to Slender Mode."

"Ah! As you wish, Oppa… Hngh…♥"

Rui-lin closed her eyes tightly and concentrated while still kneeling.

"Ooh…?"

Her breasts and hips slowly shrank. Her curvy figure returned to its previous slender state in an instant.

Rui-lin had returned to her delicate, cute appearance from just before becoming a slave. The shift from a mature, glamorous aura to a shy and adorable one suggested that the skill affected more than just her body—it subtly altered her presence as well.

"I'm back to normal! So cute… Nyaaah♥"

Chae-ryeong curiously stroked the slender-mode Rui-lin, swishing her tail and rubbing it against her face.

"I can enjoy both the cute version and the mature version from the same girl… Not bad. Even aside from the fun factor, it has plenty of practical uses."

Since Rui-lin was a wanted criminal, going outside had been difficult. In Glamour Mode, she could easily blend in. It would also serve as a smokescreen against the Hero Alliance, who only knew her previous slender appearance.

"Now… switch back to Glamour Mode."

"Yes…♥ Haaah…♥♥"

Following Si-yoon's command, Rui-lin concentrated again. Her body began to change, returning to its full, glamorous form.

"Haa…♥ Hngh…♥ It feels good…♥"

Even the act of transforming seemed to bring her pleasure. After the change finished, she continued to breathe hotly.

"Time to taste my new-type little sister too. Right? Of course… I should reward my well-behaved black cat as well."

Si-yoon refastened the collars around Chae-ryeong and Rui-lin's necks and pulled them forward.

"Aah…♥ Oppa…♥"

"Nyaaat…♥♥"
