10,000x Rebate System: Every Return Makes Me Stronger

Amon stormed out of his room with anger already boiling inside his chest.

He found Sidney sitting on the sofa, still giggling to herself as if she had just pulled off the greatest prank of her life.

The moment her eyes landed on him, her grin only grew wider.

"That’s what you get for not listening to me," she said in a smug tone.

Amon stood there for a second while pure irritation surged through his body.

Before he could even open his mouth, a familiar translucent screen suddenly appeared in front of his eyes.

[Quest: Discipline the Bratty Sidney]

[Current Progress: 0%]

[Quest remains active.]

’...Yeah, I was being naive to think she would behave without any repercussions.’

Amon took in a deep breath and forced himself to calm down.

After staring at the quest window for a few seconds, he finally decided to accept it.

"Ambrosia has given you too much freedom." He said coldly. "You need some medicine."

"W-what?"

Sidney’s smirk faltered the moment she noticed the serious look on his face.

Before she could react, Amon reached out and grabbed both of her wrists in one firm motion.

"W-what the hell are you doing?!" Sidney shouted, clearly surprised by how easily he had caught her.

Amon ignored her protest and used his free arm to wrap around her waist.

With almost no effort at all, he lifted her clean off the sofa.

Sidney’s eyes widened in shock as her feet left the ground. "Put me down right now, you bastard!"

Amon simply turned around and sat down on the sofa, pulling her with him.

In one smooth movement he positioned her across his lap so that her back was facing him, her upper body rested against the cushions.

Sidney immediately began struggling, twisting her body and kicking her legs in an attempt to break free. "Let go of me! I’m going to kill you when I get up!"

Unfortunately for her, Amon’s strength had increased far beyond what it used to be.

No matter how much she thrashed around, she could not escape his grip.

He kept one arm firmly across her back, pinning her in place while his other hand reached for the hem of her skirt.

The moment he lifted the fabric, Amon froze for a brief second.

Sidney was wearing a pair of tight black shorts that barely covered anything.

’...This fucking pervert.’

The soft shape of her ass looked far better than he had expected.

For a short moment his mind went completely blank.

’...Shit.’

He quickly forced those thoughts aside and reminded himself of the quest.

Without giving her any more time to struggle, Amon raised his hand and brought it down hard across her right cheek.

Smack!

Sidney’s body jerked forward. "Ah--! What the fuck?!"

Amon did not stop. He immediately followed with another sharp spank on the other side.

Smack!

"Stop it! That hurts, you asshole!"

He ignored her complaints and continued, alternating between both sides with force.

Each slap produced a clear, sharp sound that echoed through the living room.

Sidney’s struggles grew more frantic, but Amon’s arm kept her locked in place without any difficulty.

"Let me go already!" she yelled, her voice rising in pitch. "I’m serious! Stop!"

Amon’s hand came down harder this time.

Smack! Smack! Smack!

The black fabric of her shorts did little to soften the impact.

After several more spanks, he decided it was not enough.

He simply pulled the shorts down to her thighs, exposing her bare ass completely.

Sidney’s face turned bright red the moment she felt the cool air against her skin. "You fucking pervert! Don’t you dare—!"

Smack!

Her protest was cut short by another firm slap.

Amon kept a steady rhythm, making sure every strike landed with clear force.

The soft flesh of her ass quickly began to turn a visible shade of pink under his hand.

Sidney’s voice started to change.

The pure anger in her tone gradually mixed with pain. "It hurts... stop it already!"

Amon did not slow down. He continued spanking her harder, focusing on the same spots so the sting would build up properly.

Sidney’s legs kicked uselessly against the sofa while her hands clenched the cushions in front of her.

"I’m sorry, okay?! Just stop!"

The words came out almost unwillingly, but Amon still did not stop.

He delivered several more solid spanks, each one drawing a sharper cry from her.

"I said I’m sorry! It fucking hurts!" Her voice cracked slightly on the last word.

Amon could hear that she was getting close to the edge.

He raised his hand once more and brought it down with force.

Smack!

Sidney’s body tensed hard against his lap. "I’m sorry! I’ll stop messing with your stuff! Just quit it already!"

Tears had started to form at the corners of her eyes.

Her voice was no longer filled with pure defiance; instead it carried clear frustration and the beginning of genuine distress.

Amon finally paused and looked down at the reddened skin of her ass.

Both cheeks had turned a solid pink, and a few spots already looked slightly darker.

Sidney was breathing heavily, her shoulders trembling as she tried to hold back the urge to cry.

He kept his arm across her back for a few more seconds, making sure she understood the situation was still under his control.

Only when her struggles completely stopped did he slowly release her.

Sidney immediately scrambled off his lap and pulled her shorts back up with shaky hands.

Her face was completely red, and she refused to look at him directly.

"You’re the worst..." she muttered, her voice still shaky.

Amon simply leaned back against the sofa and watched her.

The system window updated in front of his eyes.

He closed the screen without comment.

Sidney rubbed her sore backside and glared at him through watery eyes, but she did not try to hit him or throw anything this time.

Instead she turned around and stormed toward her own room, slamming the door behind her with more force than necessary.

Amon remained seated on the sofa for a while longer. ’That should be enough for now.’

He flexed his hand once, still feeling the faint sting on his palm from the repeated impacts.

Then he stood up and walked back toward his destroyed room, already thinking about how long it would take to clean everything up.

’Fuck my life.’
