Night fell quietly over the Butterfly Mansion.
Inside Shinobu's room, she sat stiffly on the edge of the bed, fingers clenched so tightly around the hem of her clothes that her knuckles had gone white. Her purple eyes shimmered with nervous ripples. Anyone could see how tense she was.
Shuya stood by the door after locking it and immediately understood—she wasn't ready. And this whole revenge plan of hers… the fact that he had agreed to it… yeah, this was definitely not his finest moment.
He scratched the back of his head, voice uncertain. "We can still call it off, you know."
Shinobu's reaction was instant and explosive.
"No way!" she snapped, like he'd stepped on her tail. "We've already come this far. There's no turning back now!"
She bit her lip, swallowed hard, then gave him a small, determined nod. Her voice came out shaky but firm.
"Do it."
She squeezed her eyes shut, body trembling slightly as she waited.
Her plan was simple in concept: give her sister the exact same experience she had suffered through last night. Make Kanae feel every second of it through their link. The only real difference was the location.
The Butterfly Mansion was large, but the main residents—Shinobu, Aoi, Kanao, and the revived Kanae—all had rooms in the central building. And right now, Kanae's room was directly next door.
Shuya let out a slow breath.
This was the second time Shinobu had offered herself to him. The first time had been to protect Kanao and gain his power. This time… it felt different.
He sat beside her. Even without touching, he could feel the heat radiating off her skin. When he slid an arm around her waist and pulled her closer, that warmth only grew stronger.
He kissed her nose, her cheek, the sensitive spot behind her ear—then finally captured her lips.
His hands moved toward the collar of her uniform, ready to undress her.
"Wait."
Shinobu pushed lightly against his chest, breaking the kiss. Her face was flushed deep red.
Shuya paused. "Changed your mind?"
She shook her head. "I'll do it myself."
Shuya raised an eyebrow but leaned back, giving her space.
Shinobu took a deep breath, then reached up and began unbuttoning her clothes one by one. The fabric slid off her shoulders and pooled around her. She instinctively tried to cover herself with her arms, skin glowing with embarrassment.
Shuya's voice was quiet and sincere.
"You know… you're really beautiful, Shinobu."
Before she could respond, he kissed her again—deeper this time. The room quickly filled with the sound of soft breathing and rustling sheets.
Next door, in Kanae's room, things were far less peaceful than either sister expected.
Kanae had invited Aoi to sleep with her tonight as part of Shinobu's "punishment." Neither of them had any idea what was about to happen.
Kanae currently had Aoi wrapped in her arms, playfully nuzzling against her like an affectionate cat. She took a deep breath against Aoi's neck and sighed happily.
"You smell so nice, Aoi~"
"Stop messing around, Kanae-nee," Aoi complained, pushing her head away. "You promised you'd tell me about last night. Come on, spill it."
Kanae smiled mischievously, clearly enjoying teasing her. "Tell you about what, exactly?"
Aoi's face turned red. "You know what! That thing!"
Kanae just hummed, refusing to make it easy.
Aoi eventually gave up and clung to her arm, voice turning slightly whiny. "Kanae-nee~ Please?"
Kanae finally relented with a soft laugh. She hooked a finger, motioning Aoi to come closer so she could whisper.
Just as she leaned in, ready to describe last night's events, a sudden, overwhelming wave of pleasure crashed through her body.
Her words died in her throat.
Kanae's entire body jerked. She collapsed forward against Aoi, pressing her face into the girl's shoulder as a broken sound escaped her lips.
Aoi froze. "Kanae-nee? Are you okay?"
"I'm… fine…" Kanae managed, though her voice was shaky and completely unconvincing.
Another intense wave hit her. She bit down hard on the blanket to muffle the sound that tried to escape.
Aoi's worry spiked. She touched Kanae's arm and immediately pulled back.
"You're burning up!"
"I'll go get Shuya and Shinobu—"
"No!" Kanae grabbed her desperately, voice hoarse. "Don't… don't call them…"
She couldn't let them see her like this. Not when she had no idea what was happening to her body.
Aoi hesitated, torn between concern and Kanae's pleading. Before she could decide, Kanae yanked her back down and clung to her tightly.
Then it hit again—stronger.
Kanae's body arched. A muffled, broken moan vibrated against Aoi's shoulder as she desperately tried to stay quiet.
Aoi's eyes widened in shock.
She recognized this.
This was exactly how Yuriko and the others looked when they were with Shuya in Greed Island. The trembling, the heat, the overwhelming pleasure they couldn't control…
Kanae-nee was… feeling it right now?
Before Aoi could fully process the realization, Kanae's arms tightened around her like a vice. Her breathing turned ragged against Aoi's neck.
Then came the soft, breathless apology.
"I'm sorry… Aoi…"
Aoi's mind went blank as she suddenly understood exactly what was about to happen to her.
And there was nothing she could do to stop it.
