Emi Fujiwara

Age: 26

Emi currently works as a nursery school teacher and loves kids. Graduating from an all-girls school, she's a virgin with no dating experience. This is when she meets Sae, and although she's a late bloomer, she has a keen interest in all things kinky.

Emi feels like she owes Sae for everything she's done for her, so she brings up the suggestion to have a threesome after seeing Sae becoming troubled with the issue. However, Emi finds it hard to say no and goes along with all of Yuuto's desires, despite them escalating with each request.
