Well this is my first review which I'm very happy. This is the story of of a Kazama who has very strong feelings for Kimishima who is both his older sister as well as his teacher.While in class kimishima ripped Kazama's love letter in half in front of the entire class which hurted Kazama. Later we find Kazama in the nurses office seeking counciling from Hazuki the school nurse who then gave him what I think would be male enhancement drugs and then starts to GTR Kazama who resisted at first but soon gave in to Hazuki's seduction thus we have our first h-scene. Note: GTR: GyakuNetorare (Reverse Cockold)

But it wasn't long before Kimishima is now becoming suspicious about what is going on in the nurses office after seeing Kazama shadow in the window, she head to the nurses office and catches them in the act which soon leads to her being raped by Kazama and then blackmailed by Hazuki after Kimishima threatened to have Kazama expelled as well as having Hazuki resign from the school.
