Um, you see...

Master is the first person who taught Sasha about asphyxiation play (manga)...

It was scary at first, but...

I'll never forget that first time...♥

For a while after, there were rumors spread about "a madman" and there formed a "Master sightseeing troop" outside the classroom...

But, if I can be the scapegoat for my disciple, I'll do so in a heartbeat, no matter the cost to my reputation!
