Mio hesitated for a moment, then nodded.

"Alright, Onii-chan. I'll form a contract with you," she agreed.

Maria, seeing that they had both agreed, grinned triumphantly.

She began drawing a Magic circle.

As a succubus—the Magic she used often had strange side effects.

This particular contract Magic circle, for example, would cause an uncontrollable desire for physical intimacy if the servant disobeyed their master's orders or felt guilty.

The only way to alleviate this side effect was through... well, you know...

Otherwise, it would persist indefinitely.

Roy watched Maria prepare the Magic circle with amusement.

"Onii-chan, let me tell you about the Demon Realm," Mio offered, explaining the various factions and their relationships.

Roy listened with interest.

Mio's father was the previous Demon Lord, an incredibly powerful being. Although he was rumored to be dead, he had actually faked his death.

Roy didn't know why he had done that.

Maria's father was also the previous Demon Lord—making Mio and Maria half-sisters.

Mio, with her exceptional talent and strength, surpassed all her peers and even some older Demons.

But the immense power inherited from her father was suppressing her own abilities.

Roy found this rather ironic. The old Demon Lord hadn't made proper arrangements for his daughter before his "death" and had instead created problems for her.

He chuckled and shook his head, then turned his attention back to Maria.

"Onii-chan, Mio-sama, the contract Magic circle is ready. We can begin now," Maria announced with a smile.

"Alright, let's start," Roy said, taking Mio to the center of the Magic circle.

"Since this is Mio-sama's first time using contract Magic, let me assist you," Maria offered, taking Mio's hand.

Mio didn't refuse.

"Onii-chan, all you have to do is kiss the Magic circle that will appear on Mio-sama's arm," Maria explained to Roy.

"Okay," Roy replied with a nod.

Maria activated the Magic circle.

But the Magic circle didn't appear on Mio's arm. It appeared on Roy's arm instead.

As expected, Maria had tricked them.

She must have been following Zolgear's orders, and there was definitely some hidden motive behind this.

"Wait—Maria, what's going on?" Mio exclaimed, confused and flustered as she saw the glowing Magic circle on Roy's arm.

"Oh? That's strange. It seems I made a mistake somewhere," Maria replied with a feigned innocence.

"What do we do now?" Mio asked, worried.

"Well, the Magic has already been activated. We can't stop it now. How about Mio-sama kisses Onii-chan's hand instead?" Maria suggested with a mischievous grin.

"What?!" Mio blushed.

She didn't mind becoming Roy's servant, but the thought of it made her incredibly shy.

After all—she would have to obey her master unconditionally.

She glanced at Roy, her face burning red.

"Mio-sama, hurry up! The Magic circle on Onii-chan's arm is about to disappear. If you don't kiss it in time, there might be consequences," Maria urged, noticing that the Magic circle was flickering.

"Ah..." Mio hesitated, her heart pounding.

After a brief internal struggle, she finally made up her mind.

She approached Roy and gently kissed the back of his hand.

However, due to her hesitation, the Magic circle had already vanished by the time her lips touched his skin.

"It... it's gone!" Maria exclaimed in surprise.

Mio froze, her body suddenly paralyzed. A purple collar with a heart-shaped pattern appeared around her neck.

"What... what's happening?" she stammered, a strange sensation coursing through her body.

She collapsed to the ground, her legs no longer able to support her.

"What's wrong?" Roy asked, pretending to be concerned, though he was secretly thrilled.

"The curse has been activated," Maria explained.

"Curse?" Roy asked, playing along.

"Ehehe..." Maria giggled nervously, then explained, "The Master-Servant contract is meant to ensure the servant's loyalty. But because I used my Magic, if the servant disobeys the Master's orders, they'll become—insatiable..."

Mio, lying on the floor, her face flushed and her body tingling, moaned, "Stop talking and help me!"

Even Roy couldn't help but gulp, seeing Mio's alluring state.

"Don't worry, as long as you obey Master's orders, the curse will be lifted," Maria reassured her with a smile.

....

Mio looked at Roy with pleading eyes.

"Onii-chan, please help me!"

Roy couldn't refuse such a request. Ignoring Maria's presence, he began to "discipline" Mio.

"Amazing!!" Maria cheered from the sidelines, her face flushed with excitement.

Roy was speechless. Not only was Maria not embarrassed, but she was actively cheering him on. It seemed he would have to 'discipline' her as well.

He couldn't let her keep leading him around by the nose.

....

Within few minutes, Mio had climaxed seven times, eventually passing out from exhaustion.

Roy glared at Maria, who was still cheering.

Maria, sensing his dangerous gaze, chuckled nervously. "Um, Onii-chan, I'll go back to my room and sleep now."

She scurried away.

Roy sighed and carried Mio to bed.

...

The next morning, Roy woke up to find Mio staring at him with a lovestruck expression.

"Mio, what are you looking at?"

"Onii-chan, I... I..." Mio stammered, then buried her face in his chest, flustered.

Roy chuckled. Mio was quite shy, it seemed.

But although she could control her words, her body was honest.

And due to the side effect of the contract, whenever Mio disobeyed her Master's orders, she would experience a strange sensation.

A purple, heart-shaped collar appeared around her neck.

Mio moaned, her face turning crimson.

"Mio, what's wrong?" Roy asked with a playful smirk.

"Onii-chan..." Mio, seeing his teasing expression, realized he was just messing with her. She pouted and snuggled closer.

"Haha, alright, alright, I get it," Roy said, giving in to her adorable act.

He spent the morning "training" her until Maria's calls finally forced them out of bed.

...

During breakfast, Mio glared at Maria, who was smirking at her.

If it weren't for Maria's messed-up spell, she wouldn't be in this state. But—it wasn't so bad either.

She glanced at Roy and blushed.

"Mio, I don't think we should let Maria tease you like this. How about we make her sign a contract with me too?" Roy suggested with a chuckle after breakfast, while Maria was cleaning up in the kitchen.

Mio's eyes lit up. This was a perfect opportunity for revenge.

"That's a great idea! I'll go talk to her. If she doesn't agree, hmph!" Mio declared with a mischievous grin.

She went to the kitchen and told Maria about the plan.

Maria froze, hearing Mio's words. She hadn't expected this.

Although she was a succubus, she valued her chastity.

Even Zolgear—hadn't been able to sway her. She had used a special lock to protect herself.

No one could take her first time without her consent.

Maria actually had a more developed figure than Mio, but due to the lock, she appeared as a little girl.

"But Mio-sama, the contract Magic can only be activated during a full moon," Maria said with a nervous laugh.

"Is that so?" Mio asked suspiciously.

"Of course," Maria insisted with a nod.

"Fine. We'll just have to wait until next month then," Mio said, disappointed that she couldn't enact her revenge immediately. But she wasn't going to let Maria off the hook.

The full moon had already passed. They would have to wait for the next one.

"Ugh..." Maria's face fell.

She reluctantly agreed. She had a month to come up with a plan.

Roy, in the living room, overheard their conversation and chuckled. Maria wouldn't be able to escape now.

...

At school...

"Good morning, Nonaka-san," Roy greeted Yuki with a smile as he entered the classroom.

Yuki frowned, seeing Roy and Mio holding hands.
