The Noble Lady Who Offered Her Panties for Butter Cookies Signs the Slave Contract

Kael gazed at Serenity with a gentle smile and asked softly, "Serenity, wouldn't you like to keep eating food like this from now on?"

Serenity's tear-filled eyes sparkled as she nodded vigorously. "Yes, Lord Kael...! I want to eat it, I absolutely must! No, please... please let me keep eating like this forever!" Her voice trembled with desperate longing.

Having tasted the butter cookies, she didn't hesitate for a second. Kael smiled and continued, "If you become my slave, you'll get to enjoy delicious meals like this every single evening."

At the word slave, Serenity's pupils quivered. She glanced cautiously at Ring and Ming before asking carefully, "Um... are those two commoner sisters also your slaves, Lord Kael?" She deliberately avoided mentioning Professor Lucia. Unlike the common-born Ring and Ming, inquiring carelessly about a noble-born archmage like Professor Lucia felt dangerous, so she treaded lightly.

Kael shook his head and let out a cold laugh. "No, Ring and Ming aren't slaves. They're my women. But you have to come in as my slave. That means you'll rank below them. That's a rather difficult truth for a noble bitch like you to accept, isn't it?"

He openly called her a bitch and treated her as inferior. Serenity's face turned deathly pale. As the young lady of House Esmeral, the thought of falling beneath commoners was a humiliation she had never even imagined. She bit her lip hard, hesitating.

Seeing her waver, Kael pressed on. "You know it's already too late to turn back, right? You just begged me pitifully in front of all the students. They all cursed you for acting so pathetically. Even if you try to back out now, you're already marked."

Serenity's hands began to shake. The students' contemptuous stares from the clearing flashed through her mind.

Kael's temptation continued. "However," he said, "if you become my slave right now, you'll be a pioneer. Once they see you enter as my slave, countless other bitches will rush to follow. You'll end up in a far higher position than those who mocked you. Then you could even enforce 'discipline' however you like, couldn't you?"

Kael stared at her and smiled. "You'll rank higher than Irina Rosengart, of course, and even above Princess Elenora Caldria."

At the declaration that he would even enslave Princess Elenora, Serenity's eyes widened. Yet she couldn't help thinking that with Kael's abilities, it might actually be possible.

Still, she clung to one last thread of hope. "Couldn't I at least be... a concubine?"

"No. It's slave or nothing. That can't be changed here."

Kael stepped closer and slipped his hand beneath ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the skirt of her one-piece dress, firmly grabbing her bare ass. The soft, elastic texture sent a pleasant sensation through his fingertips. At the same time, he waved a butter cookie in front of her face with his other hand.

"Ugh...!" Serenity flinched, her face flushing red. Her gaze was drawn far more to the butter cookie than to the hand on her rear. The rich, savory aroma teased her nose. Saliva pooled between her lips and dribbled down her chin before she hastily wiped it away with the back of ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her hand.

After yesterday's frankfurter sausage stick and then enduring another day of that wretched coarse black bread, the butter cookie was an unbearable temptation. In the end, she opened her mouth like a pet receiving a treat from its master and devoured the cookie in frantic bites.

The rich, buttery flavor filled her mouth once more. "If you become my slave, you can eat foods like this every day. But the choice is yours. I'm not forcing you. Will you become my slave? Or will you live the next thirty-three years eating nothing but coarse black bread? If that's what you want, you don't have to sign the contract. I simply won't give you any real food until you graduate. That's all."

Terror flooded Serenity's eyes. She bit her lip and closed her eyes tightly. "I'll... become your slave."

In the end, she couldn't overcome her fear and declared herself willing to become a slave. At that moment, Professor Lucia retrieved a glowing magical contract and a quill from her subspace. The words Slave Contract were clearly written on it. It was a contract designed for sisters who willingly sold themselves into slavery. Unlike a master-servant contract, this one required the signer to willingly degrade themselves and swear absolute obedience. It only took effect with voluntary consent, but it carried an incredibly powerful magical binding force. Since it involved 'selling' oneself into slavery, the buyer was also required to pay an appropriate price. In Kael's case, that price was food.

"Ugh..." Serenity's hand trembled as she held the quill. The reality of becoming a slave crushed her pride beyond measure. But she couldn't resist the temptation of the butter cookies. The ecstasy she'd just experienced still swirled through her mind.

"Hesitating? If you want to eat coarse black bread for the rest of your life, that's fine with me."

Kael pulled out another butter cookie and waved it in front of her face. The moment it touched her lips, Serenity shoved it into her mouth and, with trembling hands, signed her name on the contract. The document blazed with brilliant blue magical energy. Her soul had become bound to Kael.

Serenity felt herself become a slave of her own volition, legally Kael's slave across the entire continent, and her body shook with self-loathing. But the choice was irreversible. Strangely, accepting it brought a sense of relief. She swallowed the butter cookie in her mouth, then knelt deeply before Kael and begged, "Master... please bestow delicious food upon your humble servant..."

Kael smiled with satisfaction and lifted her by the shoulders. "Well done, Serenity. Congratulations on becoming my first slave."

He pressed his lips against hers. Serenity obediently yielded to the kiss, responding without resistance. Kael's hand slipped beneath her dress once more, kneading ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her bare ass.

"Mmph...!" Serenity's body trembled faintly, but she offered no resistance. As his slave, she could move freely unless he commanded otherwise. Yet her free will could be stripped away at any moment if he issued an order. If he used his authority of absolute command, she would have no choice but to obey.

"From now on, you will address Ring and Ming with proper respect. Those two are far above you."

Serenity's face hardened with humiliation. A noble like her addressing commoners with honorifics was an unimaginable insult. But as a slave now, she clenched her teeth and accepted reality.

"Yes... I understand..." She looked at Ring and Ming with a trembling voice. "Lady Ring... Lady Ming..."

Ring and Ming exchanged awkward glances. Then Ring spoke to Kael cautiously. "Lord Kael... is it really all right for commoners like us to be addressed with honorifics by nobles?"

Ming added with a worried look, "It won't cause any trouble for you, will it?"

Kael nodded. "Don't worry. And get used to it. Soon enough, even Princess Elenora will treat you as her superiors. You're my women, so naturally you rank above a slave like Serenity."

Ring and Ming still looked uncomfortable, but they nodded at his words. "Yes, Lord Kael..." "Understood, Lord Kael..."

Kael smiled at Serenity. "Now then, Serenity. Normally I'd only guarantee you dinner, but... you're my first slave. It's your first day, and it's a special occasion. Feel free to enjoy teatime. Eat as many butter cookies and drink as much tea as you like."

Her eyes lit up. "Thank you so much!"

Tears glistening, she approached the table and picked up a butter cookie. The crisp treat crumbled in her mouth, releasing a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠rich buttery aroma and sweet sugar that coated her tongue. The flavor was so heavenly it made the desserts of House Esmeral seem pathetic. She devoured the butter cookies in a frenzy.

"Hic... it's... it's too delicious...!"

Serenity was completely absorbed in eating the butter cookies. When her throat grew dry, she stood and drank the hot tea straight from the cup. Cookie crumbs clung to the corners of her mouth, but she had no attention to spare. She ate with ravenous desperation, though the ingrained manners of nobility still showed through. Even so, thoughts of graceful poise were the last thing on her mind.

When she had nearly devoured the entire plate by herself, Kael purchased more butter cookies.

"Serenity, push your ass out while you eat. Bend at the waist."

At Kael's command, Serenity immediately changed her posture. She leaned over the table, hips pushed back. Her thin-strapped dress rode up naturally, exposing a generous portion of her bare ass. Kael stroked the soft flesh and smiled. "This looks absolutely delicious."

Professor Lucia chuckled. "You've acquired quite the fine first slave, Lord Kael."

"Indeed. Those bastards still have about fifty minutes before they come out of the gate... so I might as well enjoy myself until then."

While the students suffered inside the gate, Kael intended to spend the time savoring Serenity's body. He was already looking forward to their reactions when they finally emerged.
