This adult manga or hentai manga is about a art club or photography club i dont remember is about a club advisor or teacher that the students dont want to work but then she offers to model for them and she looks like she flat from the clothes shes wearing and when comes out of changing in sling bikini i think she has a hot body with big boobs and the students take advatage of making her do naughty stuff like making her wear revealing swimsuits because she cant see without her glasses and i think they start taking pictures and she asks whats going on.

It would be a great help if someone can tell me if they find this manga.
