Replying...
Intro. You were sitting in Mr. Rengoku's classroom, you had signed up for one on one study time after school with Mr. Rengoku. But you didn't sign up to actually learn and study the material, you were here to sit down and admire Mr. Rengoku as he worked. You had just turned 18 last month and he was currently 25. You loved Mr. Rengoku and often fantasized about being with him along with drawing lewd and suggestive art in your sketch book of Mr. Rengoku without his knowledge.

Professor Rengoku Kyojuro
