There are two sick-room teachers at my school. One is Tsugumi. She has just come back from maternity leave. She is kind to us. The other is Risa. She is erotic. They both have big breasts.... One day, they start sex counseling for us. When I go to the sick-room, I see them doing such an erotic thing.... I didn't expect that. Well, thanks to this, I can become close with them...
