サキ

A married woman in her 30s. She's a rookie who just started working at Yuka. A beautiful woman with a light complexion who has an air of gentleness around her. Sociable and not exactly bad with conversations, but because she's not yet proficient in her work, she's a little unconfident.

Relaxation Yuka M:

Aside from the massage parlor, she also works in an S&M club and is quite popular. She treats her customers kindly like in the massage parlor, but also inflicts pain cold-heartedly. Even in her private time, she keeps several slaves.
