Chocolate Milk Is Worth Becoming a Slave For

"Clean."

Professor Lucia's Clean spell rippled outward, spreading across the clearing.

A wave of blue light washed over everything. When it touched Kael and Serenity, their bodies were left spotless. The sweat clinging to Ring, Ming, and Professor Lucia vanished as well.

Even the semen, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠bloodstains, and perspiration that had covered Serenity's skin disappeared without a trace.

"Well done, Lucia."

"Thank you, Master Kael."

Lucia bowed her head with deep respect at his praise. Kael gently stroked her hair before turning his attention to Serenity.

"Haa..."

Serenity let out a soft, trembling moan. The aftermath of losing her virginity left her legs visibly unsteady. Her deep green eyes quivered with exhaustion, her cheeks burned a vivid crimson, and the hot breaths slipping between her lips were unmistakably erotic. Her body continued to twitch with tiny, lingering spasms.

"You've worked hard, Serenity. Now it's time to publicly declare that you're my slave—my property."

Kael stroked her hair as he spoke. He opened the shop window and purchased a white crop top and short denim skirt perfectly fitted to her measurements.

The white crop top and short denim skirt materialized on the table. Kael handed them to Serenity.

"Change into these."

"Yes, Master. But... what about underwear?"

Kael gave a small smirk at her question.

"There isn't any. Don't wear underwear for the time being. That's an order. Without my permission, you are never to wear any kind of underwear."

Serenity bit her lip, her face twisting with shame. Still, her hands trembled as she accepted the clothes.

She slipped out of the strapless dress she'd been wearing and changed into the white crop top and short denim skirt. The top exposed her midriff while the skirt barely covered her thighs. Because it was so tight, the slightest breeze seemed to slip underneath it with ease.

The cool air flowing beneath the skirt against her bare skin made her body even more sensitive. Serenity's deep green eyes trembled with embarrassment at the constant stimulation.

"Oh~ That looks incredible on you."

Kael let out an appreciative hum as he stroked her ass.

"Thank you... Master."

Serenity lowered her head as she spoke. Every time his hand caressed her rear, her body jolted involuntarily. She was still hypersensitive from the afterglow of sex.

"Here. This is your reward for becoming my slave and wearing the uniform reserved for my women."

Kael opened the shop window again and purchased a 500ml carton of chocolate milk.

"Open it, stick the straw in, and try ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠it."

He handed her the carton. A plastic straw was attached—the kind that didn't exist in this world. Of course, Serenity had no way of knowing that.

"Thank you..."

With shaking hands, she opened the carton, inserted the straw, and took a sip. Her eyes flew wide open.

The deep, rich sweetness of chocolate blended perfectly with the smooth, savory warmth of milk, wrapping around her tongue. Even as a noble, fresh milk had been a rarity for her. She hadn't even realized it was milk at first, only understanding after the flavor fully registered.

The sweet aroma of chocolate milk filled her mouth, and a comforting warmth seemed to spread through her entire body. She drank with frantic intensity, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠draining the carton in moments. The sweetness sliding down her throat made even the humiliation of the slave contract feel like a worthwhile price.

"Wh-what is this? How can anything taste this good?"

Serenity asked, her face glowing with ecstasy and disbelief. The butter cookies had been delicious, but the shock of the chocolate milk was on another level entirely.

"It's called chocolate milk. Did you like it?"

"Yes! It was... it was really... incredibly delicious... I never imagined something this sweet and wonderful could exist."

Serenity licked her lips, savoring the lingering taste as if she wanted to treasure every last trace. Seeing her like that, Kael bought her another carton.

"Here you go."

"M-Master Kael..."

Gratitude flooded Serenity's heart. The simple kindness of offering her a second carton sent waves of emotion crashing through her. In that moment, even the humiliating position of slave felt like a brilliant choice.

Just then, students began staggering out of the nineteen gates. Their ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠condition was pitiful. The ninety-four students from the Magic Department were completely exhausted from fighting monsters.

They had no visible wounds, but their eyes were heavy with fatigue and their clothes were in tatters. After all the suffering inside the gates, the first thing they saw was Serenity standing close beside Kael.

She was wearing the white crop top and short denim skirt, eagerly drinking from a strange rectangular container through a straw. Her deep green eyes sparkled with pure bliss, her cheeks were flushed, and Kael's hand was visibly gripping her ass. The sight made it perfectly clear that she had become his woman.

"Is that really the Viscount Esmeral's daughter wearing those clothes?"

"Did she actually sell her body to Kael?"

"She must have gotten something pretty good in return for spreading her legs. Hmph!"

The female students especially looked on with a mixture of contempt and envy. They despised Serenity for trading her body for food, yet they burned with jealousy knowing she had tasted the butter cookies and more. The look of pure ecstasy on her face only intensified their conflicted feelings.

They don't know what chocolate milk is yet, so of course they'd react like this.

It was only natural. In this world, no one had any concept of chocolate or chocolate milk.

"You all must be thirsty after everything you've been through. Lucia, could you divide this up and give them each a small portion? About one-fifth of what Serenity drank."

Lucia smiled at Kael's words. She had immediately understood his intentions.

"Yes, Master Kael. That's possible."

She took out ninety-four wooden cups from her subspace. They were roughly made but functional, complete with handles.

Kael opened the shop window and purchased ten 1L cartons of chocolate milk.

Ten cool 1L cartons of chocolate milk appeared. Using magic, Lucia carefully poured roughly 100ml into each of the ninety-three cups. About 700ml still remained.

"You can drink the rest yourself."

"Thank you!"

Lucia expressed her gratitude for the unexpected bonus. She then distributed one cup each to the ninety-three Magic Department students, excluding Serenity, Kael, Ring, Ming, and Pinit.

"What is this?"

"It looks like what Serenity was drinking."

The students initially eyed the unfamiliar brown liquid with suspicion. But they had seen how blissfully Serenity drank it, and even Professor Lucia seemed delighted with her leftover portion. When Rhea Halley, drawn by the sweet aroma, took the first sip, her eyes widened dramatically.

"I-it's delicious!"

The smooth, melting sweetness filled her mouth, and Rhea drained her cup in seconds. Seeing her reaction, the other students followed suit.

"Th-this is too good..."

"Mmm... it's making me crave more!"

"This is way too little! It doesn't even quench my thirst!"

Both the girls and boys were thrown into chaos by the sweet, velvety taste of the chocolate milk. The tiny 100ml portion was enough to tease their tongues but nowhere near enough to satisfy them. The lingering sweetness in their mouths only intensified their thirst.

"What the hell is this? Why am I the only one who doesn't get any?"

Pinit, the only one completely denied even a taste, shouted in rage. Before Kael could respond, Professor Lucia spoke first.

"Pinit, be quiet. Or would you prefer I freeze all your limbs and display you on the castle walls?"

Her threat instantly silenced his protest. Meanwhile, the students who had tasted the 100ml of chocolate milk turned their complaints toward Kael. Their voices shook with a mixture of anger and desperate longing.

The sweet aftertaste of chocolate milk still coated their tongues, tormenting their senses and making the craving even worse.

"Serenity got to drink that much, but we only get this?"

"Exactly! This is completely unfair!"

Kael found their complaints utterly shameless. Just as Lucia had said, people pushed to their limits truly became selfish creatures.

"Shouldn't you all be thanking Serenity? Because she became my slave and pleased me, the amount of food I can summon has increased slightly. That's why you were all able to taste chocolate milk at all... Yet instead of showing gratitude, you're demanding more. Don't you think that's a bit much?"

The students' faces stiffened at his words. Professor Lucia added coldly:

"How shameless. You happily ate what Serenity earned through her efforts, yet now you demand the same amount she received. Don't you think your thieving mindset has gone too far?"

The students glanced at each other nervously. They had all witnessed Pinit's downfall and were terrified of suffering the same fate.

Kael might very well cut tonight's portion in half again if he grew displeased. The thought made them watch his expression carefully.

"Still... she got to drink so much..."

"We only got this tiny bit..."

Even though they knew they owed Serenity for being able to taste chocolate milk at all, they felt no gratitude. Instead, they stared at her with eyes full of jealousy and envy.

"Serenity, continue to please me as my slave from now on. If you do, you'll get to enjoy these kinds of snacks often. Of course you'll have delicious dinners every evening, and if you behave especially well, I might even prepare something special for breakfast or lunch."

Serenity's face brightened. She felt certain that choosing to become Kael's slave had been the wisest decision of her life.

"Thank you, Master!"

In front of the many watching students, Serenity bowed her head respectfully and openly called him Master.

"The viscount's daughter is calling him Master?"

"She has no pride left."

Some of the girls whispered insults about Serenity, but their eyes were filled with envy.

What if I offered my body to Kael too?

Could I get to eat things like this every day if I became like Serenity?

A few of the female students found themselves tempted by the idea of surrendering their bodies and even becoming his slave if it meant enjoying such food daily.

The lingering taste of chocolate milk in their mouths only fanned the flames of that temptation. After seeing the benefits Serenity gained by becoming a slave, they found themselves craving the chocolate milk far more than they feared the humiliation of submission.

This is dangerous. To think he's led the situation this far.

Irina bit her lip as she watched the scene. The sweet aftertaste of chocolate milk still lingered in her own mouth. When her eyes met Kael's, she tried to turn away. But for some reason, she couldn't.

The memory of that day resurfaced—the day she had declared their engagement over. The day she had never imagined she would come to regret so deeply.
