WAAA-474 _In the middle of the night, I walked into the room of female student Shiina Koharu

Shiina Koharu is a gifted school girl. Her strong point is that she can run quickly, so Koharu receives a lot of expectations :) . To prepare for the upcoming exam, Koharu was coached by an experienced coach, Imai. However, from the first time he met Koharu, teacher Imai forgot his main mission. In teacher Imai's eyes, Koharu was a seductive girl with a big round butt, a pretty face and something very lewd, not an athlete anymore. Let's see if, with this situation, Mr. Imai can control his wrong desires for Koharu and help her achieve her best results.
