"What these two don't know is that I've hypnotized them" he whispered to the camera "just watch..."

He looked up at the two girls as they posed around.

"That's lovely girls! But Yukari, pick your nose" he said with a snap. Yukari immediately went blank, her finger lodging itself into her nostril.

"Pick her..?" Mitsuru began asking before seeing her teammate immediately shove her finger into her nose "Yukari?! What are you doing?!" She asked in surprise. Yukari, currently entranced, didn't respond.

"And Mitsuru, spank your ass" he commanded.

She too went blank, pushing out her plump ass and giving it a series of light smacks.

"Aaaand wake!"

The two looked around in confusion, before looking at Hajime

"Wh-what the hell was that?!" Yukari exclaimed.

Mitsuru's gaze went cold

"Explanation. Now" she demanded. But of course, she was in no position to make demands.
