Inside the room, Rin and Alex were in the heat of a sexual act.
The "Kuudere" (cool/stoic) girl was bold. Even hearing her sister's footsteps, she didn't stop. Alex sensed Kaede and Hazuki, knowing how shocking this would be for the tsundere sister, and tried to pull away.
But Rin refused to let go. She wrapped her arms around his neck and locked her long legs around his waist, pulling him deeper into her. She wanted to feel his heat, his shape, his massive cock thrusting deep into her womb.
It feels so good.
Rin was stoic, but she wasn't emotionless. She was deeply addicted to Alex's sexual prowess. But more importantly, she wanted to provoke her sister.
Kaede was indeed provoked. She stood frozen.
Her sister was completely naked, her perfect body exposed, pinned under the dark-haired boy who was also stark naked. Alex's body was a masterpiece—sculpted muscles, golden proportions, perfected by his system stats. To any woman, he was an irresistible temptation.
Hazuki, standing behind Kaede, was staring with wide eyes, her breath hitching. She swallowed hard, looking like a total pervert.
Kaede didn't notice Hazuki's reaction. Her eyes were fixed on the sight of her sister being pounded. She knew they were a couple, but seeing it was a different story. This is our house! We have guests!
And Rin... she looked so primal, so lost in pleasure. It was nothing like the Rin she knew. And Alex... you pervert!
Kaede's face went through a kaleidoscope of emotions: anger, confusion, shame. Seeing that monstrous dick sliding in and out of her sister made her feel faint.
"Sister—ahhh!!" Rin gripped Alex tight, her body convulsing in a violent climax right in front of her sister.
At the dining table, Hazuki barely dared to breathe.
The table was spread with expensive Wagyu and exquisite dishes. Kaede had clearly put her heart into this meal, but the atmosphere was suffocating. Hazuki ate her rice quietly, her eyes darting between the three of them.
Alex and Rin, however, seemed unfazed. They were busy feeding each other.
"Alex, say 'ah'~"
"Rin, I can do it myself."
"Ah~"
"Ahem... ah." Alex took the beef. Rin wiped his lip with a napkin. "How is it?"
"Delicious."
"This is A5 Wagyu," Rin noted.
"Even with A5 beef, you need skill to make it this good," Alex added. "Kaede's cooking is amazing."
The compliment hit Kaede like a physical blow. Her hostile aura deflated.
"Honestly, I can't believe you made this, Kaede. You're a tsundere, but you'll make a great wife one day. Whoever marries you is lucky."
"Who's a tsundere..." she muttered, her face heating up. Great wife?
"I wish I could eat this more often."
"Hmph, in your dreams. I don't have time to cook for you every day," Kaede pouted, her anger completely gone.
Hazuki sighed internally. Kaede is so easily handled. This Alex guy was dangerous. He wasn't like the simple boys at school. He was a predator.
But that makes it more fun. I want to see him submit to me.
"No, I meant the A5 Wagyu, not your cooking," Alex teased.
"!!!"
"Pfft, just kidding, Kaede," Alex held out a piece of beef to her. "Kaede, say 'ah'~"
To a tsundere, this was the ultimate embarrassment. But for some reason, Kaede tucked a strand of hair behind her ear and slowly opened her lips. "Ah—mm."
"Hmph... of course it's good, I made it."
The meal ended. Hazuki waved goodbye. "I'm heading out. Kaede, let's hang out again. And you too, Alex-kun..." She shook her phone. "Can I have your Line ID?"
Alex didn't refuse.
After Hazuki left, Rin went to the kitchen. Alex and Kaede were left alone in the foyer. Alex was about to explain the situation when Kaede suddenly reached behind her and shoved the black book into his chest.
"Here. Take this."
"Isn't this..."
"You wanted it, right? I took it from Hazuki. I told her I was interested in it for school. She didn't suspect a thing," Kaede looked away, fidgeting with her hair. "About your... powers. I won't tell anyone without your permission."
Alex was stunned. He smiled, stepped forward, and gave her a tight hug.
"Wha—! What are you doing?!" Kaede stuttered, her face turning crimson. But she didn't push him away. He smelled so good. He was warm and made her feel safe. Is this how Rin feels when he holds her? I'm a little jealous.
"Thank you, Kaede. I've received your... heart."
"My heart..." Was he implying something? Kaede couldn't even manage a "tsun" response. "F-fine! It's just a book. I'll go cut some watermelon."
Alex watched her run away, then looked at the black book. "A Succubus, huh? Let's see what kind of demon we get!"
