Forbidden Deviance with a True Pervert Mature Woman Until I Become a Real Sadist

Synopsis

“I’m a sadist, you know♪”

Yaito Itoda is a cram school instructor. Every day, he shamelessly flaunts his “sadist” persona, hoping some woman will eventually take the bait.

One day, he’s confronted by Chiyo Kogo, grandmother of his student Nene Suzuhara.

“I hear you’ve been going around the cram school saying you’re a sadist… what exactly do you mean by that?”

“That’s something you say among friends, not in a respectable place. Why would you say something so inappropriate to your students?”

A rightful complaint from a guardian. His job is on the line.

(When will I get fired? This is bad, really bad…!)

Days pass in anxious uncertainty. Then Chiyo appears before him.

“How does it feel to live in fear and anxiety?”

“I can barely sleep… please just report me… that would be easier…”

“That won’t do.”

She offers him a collar.

“Will you become my trainer?”
