Untie the gown's back

'Distract them.' Monaca mouthed to Kotoko who nodded back in response.

Kotoko turned to face Kaito. "Hey, I know Maki's biggest secret."

This caught both Kaito and Maki's attention. Meanwhile, Monaca went behind Maki and started to slowly untie each knot, trying to remain as silent as possible.

As Kotoko spoke, Maki's face went pale. 'Did Monaca really tell her that?'

Maki tried to cut her off. "Hey, you don't need to tell anyone." However,

"Maki's big secret is..." Kotoko paused for effect.

"She has a giant butt!" Both Kaito and Maki stopped and blinked, not knowing how to respond to what was just said.

After a few seconds, Kotoko spoke again. "Like really big. Like 'two watermelons' big. Like 'D-Cup for butts' big. Like..."

Maki cut her off. "Okay, okay. We get it." Maki said as her face went bright red. She turned to face Kaito who was staring at her which made her feel even more embarrassed.

Just as Kotoko yelled out about Maki's ass, Monaca finished untieing the last knot.

All of Maki's back was completely exposed and she was too preoccupied to notice.
