Toki-sensei wa Kigaetai - Vol. 1 Ch. 13 - Yukata

[Cordonblue]

Her sex is a coin flip between quiet intimacy and loud debauchery. Zero in
between.

 

[Raitzeno]

Pretty sure the blank is meant to be a name. It's a self insert fantasy. The person she's supposedly on a date with is never in the frame on purpose.

 

[NerimaShinjuku]

I don't think it’s a name, because of the dialogue that follows.

‘Toki-sensei likes [blank]”

“Don't say that!”

”But it’s the truth, right?”

”But…”

”With this body, your students and colleagues will eventually find out.”

It makes sense if the blank is “sex” or the name of a sex act. But “With this body, your students and colleagues will eventually find out you like ME“ doesn't track.
