Looking at the carefree Shido who was still yawning due to the lack of sleep, Kotori could only gnash her teeth in annoyance, her cheeks blushed when she remembered their animalistic behavior last night.
Yet, what made her more embarrassed was the fact that she stayed there and watched Shido and Tohka continue indulging themselves in pleasure while she herself started touching her drenched pussy to comfort her frustrated body.
It was her first time doing it and although it was shameful and embarrassing, she had to admit that the feeling of touching herself while watching the two having sex felt amazing.
When Shido was about to come inside Tohka, Kotori was initially shocked since she didn't expect that her perverted brother would really release his semen inside Tohka causing her to almost jump out of her spot and stop his action.
Yet, the feeling of immorality took over her, Kotori just gnashed her shirt to stop her voice from leaking as she watched Tohka moan while Shido poured all his white fluid inside her womb.
Kotori watched how Tohka's body kept twitching and she subconsciously imagined that it was her being embraced by Shido while lovingly pouring all his love into her petite body. Just imagining it caused Kotori to suddenly felt intense pleasure all over her body and she also reached the peak while watching Shido and Tohka.
And now, remembering those embarrassing actions of hers last night, Kotori could only silently walk beside them while maintaining a plain expression.
The three of them continued walking in awkward silence. Tohka, usually full of energy, kept glancing between Shido and Kotori, sensing something was off.
As they were about to part ways, Tohka suddenly leaned in closer to Shido, her voice quiet yet filled with curiosity.
"Shido, doesn't Kotori look.... kinda weird today?" she asked, tilting her head slightly.
"Huh? Does she?"
Shido blinked drowsily, his eyes still teary from the yawn. His lazy response did little to clear up Tohka's confusion.
Hearing his sluggish reply, Tohka revealed a pout, puffing out her cheeks. "Geez, can you be more energetic? You sounded like an old man when you talked like that."
She stomped her feet in annoyance yet Tohka seemed to forget that she was the reason why Shido felt idle in the morning.
"Isn't it because you kept asking me to give it to you again and again last night?" Shido said speechlessly. Tohka suddenly complained about his lack of energy causing Shido to sigh helplessly as this girl really knew how to throw a tantrum.
"Mooo... D-Don't say it out loud, Kotori might hear you!" Tohka replied bashfully as she felt annoyed at Shido's words.
Tohka quickly glanced behind her to check if Kotori was listening. Seeing that Kotori wasn't paying them any attention, she finally heaved a sigh of relief. However, she didn't forget to give Shido a sharp pinch on the waist, her cheeks puffed up in embarrassment.
"D-Don't say such embarrassing things, idiot Shido!" she huffed, avoiding his gaze as her face turned red.
"Ouch! Ouch! That hurts Tohka..."
Shido grimaced, his face contorted in pain.
Seeing his reaction, Tohka nodded in satisfaction before finally letting go of his waist, looking rather pleased with herself.
It didn't really hurt Shido as he had a high endurance and Pain Resistance skill, though he had to act like he was in pain as he knew how unreasonable women are. If he didn't at least pretend to be in pain, Shido was certain that Tohka would only get more riled up. So, for the sake of avoiding further trouble, he grimaced and played along.
Yet, while Shido and Tohka were busy flirting, they failed to notice the sharp gaze watching them from behind.
Kotori had been observing them all along, her crimson eyes locked onto their intimate interactions. Her expression remained neutral, but a small nerve twitched on her temple, a clear sign of her growing irritation.
'These two… flirting right in front of me?!'
Her grip on her lollipop tightened as a dark aura subtly began to form around her.
"Still, why does Kotori look strange?" After their little exchange, Tohka finally remembering the original topic. She tilted her head, her brows furrowing slightly. "She's usually more energetic, but today she's just… quiet."
Shido, snapping out of his drowsiness, finally took a closer look at Kotori. He turned back again and froze.
Kotori now had an ominous air surrounding her, yet her lips were curved into a sweet, almost too pleasant smile.
A shiver crawled down Shido's spine. Tohka, oblivious to the danger, tilted her head in confusion.
"U-Um? Kotori-san, why are you smiling like tha—"
Before Shido could finish his words, Kotori took a slow, deliberate step forward, her crimson eyes gleaming with a dangerous light.
*BAM!*
Without warning, she delivered a direct punch to his gut.
"Gwaa!"
Shido gasped, clutching his stomach as he staggered backward. Kotori's punch had completely ignored his defenses as if his high endurance and Pain Resistance skills were utterly meaningless against the legendary Imouto Punch.
"Shido!" Tohka yelped, rushing to his side and supporting him before he could fall. She looked at him with concern, her purple eyes filled with worry. "Are you okay?!"
"Y-Yeah, I'm fine..." Shido replied slowly as he tried to stabilize his breathing.
'Wh-What the heck?! Why does her punch feel so heavy?' Shido cursed inside his head. His face reveals a grimacing look as he slowly moves his head upwards and looks at Kotori's dark expression.
Still clutching his aching stomach, Shido's body remained slightly bent over, bringing him to eye level with Kotori.
Tohka, still supporting him, gulped nervously as she shifted her gaze between the two. "U-Um… Kotori? M-Maybe we should all just calm down…?" she suggested hesitantly, her voice slightly shaky.
Despite her usual bravado, Tohka was clearly intimidated by Kotori's sudden shift in demeanor. Her body trembled slightly, her grip on Shido tightening. If not for him, she might have already bolted, tears in her eyes, fleeing from Kotori's overwhelming presence.
When Kotori arrived in front of Shido, she remained her silence for a moment.
"Kotori, I—"
Just as Shido was about to speak, his words got caught in his throat as his eyes widened in shock.
In a swift motion, Kotori grabbed his collar and yanked him forward. Before he could even process what was happening, a soft, warm sensation met his lips, her crimson lips pressing firmly against his.
Shido's mind blanked out. His entire body stiffened as his brain scrambled to catch up with reality.
Even Tohka, who had been holding onto him just moments ago, was left completely frozen. Her mouth opened and closed, but no words came out.
'What… just happened?!' All she could do was watch helplessly as Kotori stole a kiss from Shido right in front of her.
For a brief moment, time seemed to stand still. Then, as suddenly as it happened, Kotori pulled away and gave Shido a hard shove, causing him to stagger slightly.
A smug smile curled on Kotori's lips, though her heavily blushing cheeks betrayed her true feelings.
"Hmph. That's your punishment," she declared, crossing her arms before swiftly turning on her heel. Without giving Shido or Tohka a chance to react, she marched off toward her school, her long twin-tails swaying with each step.
When Kotori finally disappeared from Shido and Tohka's sight, she slowed her pace, her confident facade gradually fading.
Silently, she raised a finger to her lips, tracing the lingering warmth left behind. Her crimson eyes flickered with a mix of emotions as she replayed the moment in her mind.
'I… I really did it…'
Her heart pounded against her chest, her face heating up once more. Clenching her fists, she quickened her steps toward school, trying to suppress the overwhelming embarrassment creeping up on her.
"Ughhh! What was I thinking?!" she groaned internally, her entire face turning red.
Yet, despite her embarrassment, Kotori couldn't help but feel happy, she had finally kissed Shido again. A small, satisfied smile crept onto her lips as she hugged her bag tighter.
However, that happiness was quickly replaced by panic.
"W-Wait… how am I supposed to face him now?!"
Her steps faltered for a moment as the realization hit her. She had acted all smug and confident, but the next time she saw Shido, how was she supposed to look him in the eyes?
"Ughhh! This is so embarrassing!" she screamed internally, covering her flushed face with her hands.
