[六畳] 願いが叶う保健室

I can read a bit of japanese, and from the title alone says "School infirmary that makes your dreams true". Basically the girls go and say their fetishes to the nurse and she makes them reality calling students

so worst or best nurse?

What I can get is that girl student goes to the one in charge of the clinic, tells her to call some guy or guys, then they do sexy stuff. Basically, the clinic is now a brothel of sorts.
