With a...massage?

Kawakami got behind Makoto first and began to rub Makoto's temples with her fingers.

"Empty your mind..." Kawakami said. "You feel so relaxed."

"E-empty my mind..." said Makoto.

Ren smirked. Kawakami often massaged him when she did her maid work, so it made sense she'd default to something like that for a hypnosis technique.

Makoto slumped forward in her chair, her head resting on her tits, in a deep trance. Ann soon followed suit, and they were snoring lightly.

"Now folks!" Kawakami said, addressing the audience. "One thing about hypnosis is that these lovely ladies can't do anything they don't want to do. But since this is a show, I think I can get away with a lot more."
