Bang, bang, bang—
Himemiya Makoto, still immersed in anger at Mu Xiaoxiao for not caring about atmosphere or timing, didn't respond to the knocking at first. She tilted her head, exposing part of her pale face buried in the pillow under the light.
Bang, bang, bang—
The knocking continued, accompanied by shouts.
"Makoto? You in there?"
'Is that my brother?'
Himemiya Makoto quickly tidied her clothes, wrapping herself tightly to hide her Incubus Pattern from family. She was very careful at home now, especially after bathing.
Click—
"Brother? What's wrong?"
The one standing outside was indeed Himemiya's older brother. Makoto looked puzzled. Since entering high school—or after growing up—their sibling relationship wasn't as close as when they were young. They'd grown more distant.
They rarely spoke anymore.
It was strange for her brother to seek her out now.
"I need to tell you something. Won't you invite me in?"
"Just say it here. You can't just enter a girl's room." Makoto quickly blocked him. Even ignoring the shameful silver marks on her body, she never let the opposite sex into her room after growing up.
Not even her brother.
Girls needed their own space.
"Oh, Makoto. You've really grown up." Seeing his sister's rejection, Himemiya's brother squinted. He flexed his muscles inadvertently, but Makoto ignored them.
Mu Xiaoxiao had muscles too. Not as exaggerated as her brother's, but... his superpowers weren't comparable.
'Why am I thinking about that bastard again?!'
"I saw Kaoru walk you home. Were you two on a date today?"
"Why are you asking?"
"Just curious if you two are dating." Himemiya's brother smiled slightly. "And... Makoto, you've been acting strange lately. You haven't touched my discs these past two days."
"What?! What?!"
The girl's pupils shrank.
"You don't think I don't know, do you? You keep stealing my discs." Himemiya's brother seemed pleased by his sister's shocked, ashamed reaction. He'd noticed his dirty discs missing multiple times—taken by his sister.
He knew exactly what she did with them.
"I... you..."
'He actually found out.' Himemiya Makoto's scalp tingled. She was an adolescent girl, curious about such things. She'd taken them to her room and watched secretly. They were still under her bed.
But since making that... deal with Mu Xiaoxiao, she hadn't watched those discs. After all, how could videos compare to the real thing?
Just fantasizing about Mu Xiaoxiao's fingers was enough to satisfy her...
"Lately, you haven't stolen any more discs. Could it be you've already done it with Kaoru?"
Faced with such a blatant question from her brother, Makoto's pupils trembled. Her expression turned angry. "That's none of your business?! Besides, I don't even know what kind of discs you mean!"
"Hey, I won't allow some other guy to play with my sister's body without me knowing. Besides, Makoto, don't pretend with me. Today, your big brother will show you what a real man is. Don't worry—I'll satisfy you."
'W-What is this guy talking about?'
'Is this man really my brother?' Watching the hand reaching for her, Himemiya Makoto stared at him in disbelief. She tried to close the door, but he easily blocked it by grabbing the frame.
She was completely outmatched in strength!
Just as the girl watched desperately as his hand approached her chest, the silver marks on her chest and stomach suddenly grew hot—
Hum—
Hiss!!!
"Ah—!!!"
Pain!
What?!
The searing pain like burning made Himemiya's brother instinctively withdraw his hand. Seizing the opportunity, Himemiya Makoto quickly slammed the door shut and locked it.
Bam!
Outside, her brother clutched his reddened hand, staring at the closed door. His mood darkened. Inside, Himemiya Makoto curled up on the bed, trembling under the quilt.
'What—what was that?'
'My brother—we were so close before. Why did he become like this? He actually wanted to... Pervert! Disgusting! Repulsive! This weekend really is the worst!'
Thinking of living under the same roof with such a disgusting brother, Himemiya Makoto shivered. No movement outside. He didn't break in.
Then, the girl reached out and touched her silver marks—still warm. She felt their heat and that strange sensation from before.
'Did this silver mark stop him just now?'
'It seems so. This mark actually has this power... Is it protecting me?'
Under the influence of the silver marks, her fear and concern faded little by little. Himemiya Makoto rubbed her lower abdomen with a complicated expression. Her fingertips slid downward.
Her eyes gradually blurred.
"Mu Xiaoxiao... Mu Xiaoxiao... um~"
Hoo... hoo...
She clamped her legs together. The scent of arousal slowly filled the air.
---
Living in that house was becoming more and more unbearable.
She'd encountered that kind of thing last night—blocked by her perverted brother at the door, trying to assault her... If not for the power of the silver marks Mu Xiaoxiao called Incubus Pattern, he might have succeeded.
This made Himemiya Makoto flee the house before dawn the next morning, disgusted with her own home.
The weekend was over. A new week began—time for school. But that scoundrel Mu Xiaoxiao was there too... 'Woo, what's wrong with me?' Thinking of Mu Xiaoxiao, Himemiya Makoto didn't feel disgust like she did toward her brother.
That confused her.
He'd done terrible things to her, but... thinking of these shameful silver marks and their protective power made her feel complicated. Warm inside. She could even feel a touch of tenderness.
Himemiya Makoto couldn't help blushing, remembering how she'd fantasized about Mu Xiaoxiao while pleasuring herself last night.
But Makoto's vague affection for Mu Xiaoxiao vanished the moment she saw him walking with a strange red-haired girl.
Countless emotions rushed into her heart instantly—mixed together, flavors blending.
"That scoundrel—!!!"
'Who is that woman? How many girls does he need? Aren't Chi-chan and Kisaragi Anna enough? He was just with Chi-chan last night, and now a new girl today?'
'What about me?'
Instantly, anger, grievance, sadness, jealousy—all kinds of emotions sprouted in her heart. Remembering how he'd ended things with her, the girl gritted her teeth and rushed over.
"Mu Xiaoxiao!!!"
"Huh?" Mu Xiaoxiao looked confused.
"Come with me!!"
Right in front of Obata Yui, she grabbed the boy's arm and dragged him behind the stairs. She slammed him hard against the wall in the corner. Himemiya Makoto stood very close, their eyes meeting.
The girl almost bit through her soft cherry lips.
"Mu Xiaoxiao, you bastard!!"
"???"
