The Commoner Sisters' Oath

Kael smiled as he watched the rapturous expressions on the two sisters’ faces. Their palates had been utterly transformed. Once they had tasted this new world, Ling and Ming were as good as bound to him.

Even after draining their glasses of orange juice, the sisters continued to cradle them, inhaling the lingering sweet fragrance as though savoring a precious memory. Their brown eyes still shimmered with overwhelming emotion.

“K-Kael, sir…” Ling’s voice trembled with gratitude as she called his name. She gazed at him with clear, earnest brown eyes and asked, “Is… is this truly your ability, sir?”

Ming’s voice shook with the same awe. “Can you… keep making things that taste this wonderful…?”

Kael nodded, offering a gentle smile. “Yes, this is my ability. It’s only one part of it. I can summon all sorts of things—from daily necessities to a wide variety of objects. Most of them happen to be food, of course. The sandwich and orange juice you just enjoyed are examples.”

At his words, Ling and Ming exchanged glances, as if they could not believe the scene before them was real. Once they confirmed it was no dream, their eyes sparkled with wonder and they burst into admiration.

“Sir Kael… to possess an ability like this! It’s truly incredible!”

“Sir Kael! It’s amazing! To share something so delicious with commoners like us… thank you, truly!”

Kael leaned back against the sofa with a satisfied smile, clearly pleased by their reactions. “It makes me happy to see you two enjoying it so much. But tell me, Ling, Ming—what do you plan to do from now on?”

The sisters’ eyes widened. Ling asked cautiously, “What do you mean by that, sir?”

Kael’s voice remained calm and measured. “There’s only so much I can do by simply protecting you inside the academy. So how would you feel about swearing your loyalty to me?”

“Loyalty?” Ling and Ming exchanged another glance. Even as commoners, they understood exactly what such an oath meant. It was far more than a simple ceremony. It was a vow that linked soul to soul, something that demanded the utmost care. Because it was a magical contract that forged a true master-servant bond.

Of course, it was not a one-sided demand. A lord also had duties to uphold. When a knight swore loyalty, the lord in turn contracted to protect that knight’s honor. A knight could resist or refuse any order that stained that honor. Yet if the system were abused, it could still become dangerous. Still, as the traditional knight-lord oath demonstrated, the contract flowed both ways. It was sustained only if the lord paid a fitting price for the loyalty received. There were built-in limits, safeguards of a sort.

This is exactly what I want. Absolute obedience. That was Kael’s true desire. Naturally, he would provide suitable compensation in return.

“Yes, you’ve heard of loyalty oaths before, haven’t you? I want the two of you to swear yours to me. If you do, I’ll make sure you can enjoy food like this—food I summon—every single evening.”

At his proposal, Ling and Ming looked at each other in silence. Then Ling spoke first.

“Sir Kael, the truth is… we were already planning to swear our loyalty even if you hadn’t offered us dinner.”

“That’s right,” Ming added, her voice sincere. “If it hadn’t been for you, sir, those Cad thugs would have…” She couldn’t finish the sentence.

Kael smiled at their heartfelt words. So they intended to serve me from the start. But after tasting that sandwich and orange juice, their resolve has grown even stronger. They’ve reached the point where they want to be bound to me completely, like my personal possessions.

Ling lowered her head shyly. “Sir Kael… please allow us to attend you. If you wish, as maids… or in any way at all, we want to serve you.”

Ming’s cheeks flushed as she continued, “I want to serve you together with my sister. I’ll do anything.”

Kael nodded. For a commoner to attend a noble meant far more than mere maid work. In this world, if a noble desired it, a serving woman was expected to offer her body—regardless of whether she had a lover or husband. That was simply how the class system worked. Ling and Ming’s words went beyond becoming loyal retainers; they were offering their very bodies as well.

“If that’s truly how you feel… then I accept. I will take both of you as my personal maids, bound to me. I look forward to your devoted service.”

The sisters’ faces lit up with joy. Ling bowed deeply. “Yes, Master! I will serve you with everything I have! My entire life belongs to you now, Master.”

“Me too, Master!” Ming echoed. “I’ll serve you with all my heart, right beside my sister!”

Kael decided the more complicated ritual could wait. There was no rush; they could formalize the contract later. To make the loyalty oath truly binding they would need ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠an oath document or the help of a grand mage. Asking one of the professors would be simple enough.

“Just call me Sir Kael.”

Both sisters nodded at once and bowed again. “Yes, Sir Kael!”

Having accepted them, Kael beckoned. “Then come here. Sit beside me.”

“…Yes!”

Ling and Ming flinched for the briefest moment—not from reluctance, but from the instinctive nervousness of maidens. Still, they soon offered shy smiles and settled on either side of him on the sofa. Ling took his right, Ming his left.

From this close distance he could clearly ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠see the soft, generous swell of Ling’s breasts beneath her plain clothes and the modest, perky curves of Ming’s. Their body scents drifted to him—Ling’s floral sweetness and Ming’s fresh, fruity fragrance—gently teasing his senses.

Kael casually rested his hands on their thighs. His palms settled over the smooth skin revealed beneath the short hems of their shabby brown commoner skirts. As he began to stroke those sleek thighs, the sisters only offered shy smiles, showing not the slightest hint of refusal.

“Sir Kael…” Ling whispered, her voice already growing warm.

“Sir Kael…” Ming echoed in a small voice, her eyes shimmering with a mixture of bashfulness and budding expectation.

Kael smiled inwardly at their responses. He had no need to restrain himself with these two. It was time to unleash the desires that had built up inside this vigorous twenty-year-old body. Only then would he be able to carry out his plans tomorrow with a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠clear mind.

His hands slowly slid beneath their skirts. His ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠fingertips soon met the thin, threadbare fabric of their panties.

Poor quality, as expected. Given how ragged their outer clothes were, their underwear could hardly be any better. Yet even through the cloth he could feel the growing warmth and dampness against his fingers.

“Haa… mmmh… Sir Kael… ngh!”

Ling’s breathing turned ragged; a sweet, lewd moan slipped from her lips.

“Hng… haa… Sir Kael… there… ugh!”

Ming was no different. Her small lips parted as equally erotic sounds escaped.

Kael continued to pleasure both sisters at once, carefully observing every reaction. Their clear, innocent eyes gradually clouded with heat. The fabric beneath his fingers grew wetter, slicker, the lewd moisture coating his fingertips.

“Sir Kael… we’re both virgins… so please, claim our first times,” Ling whispered, cheeks burning crimson.

“That’s right… I’m a virgin too… hehe…!” Ming added with a shy little laugh.

“Good. Very good.”

Kael was more than satisfied. In this world it was rare for a woman attending a noble to still be untouched. The ancient right of first night had long since vanished, so most serving women already had lovers or were married. Beautiful girls were usually claimed early.

They’re plenty worked up now.

He had originally intended to eat, but the sight of the sisters made lust burn hotter than hunger. To the other academy students suffering daily from the foul taste of coarse black bread, such a thought would have seemed impossibly decadent. For Kael, however, who never lacked for proper food, satisfying his desires came first.

“We’ll start with you, Ling.”

“Yes…”

Ling timidly parted her legs. Kael slowly hooked his fingers under the waistband of her panties and tugged. The thin cloth slid down her thighs, past her knees—and then tore with a sharp sound.

Riiiip—

Kael stared at the ruined scrap of fabric in his hand. The pitiful quality of it drove home just how harshly the sisters had lived.

Ling squeezed her eyes shut, more ashamed of having worn something that tore so easily than of being exposed.

I’ll have to buy them proper clothes later.

The hypermart sold clothing as well—comfortable, high-quality garments completely unlike anything in this world. They weren’t luxury brands, but the variety of modern styles would no doubt drive even the noble students wild.

And so, without even realizing it, Ling and Ming had been chosen as the first models for his new wardrobe line.
