UD-371R - Dirty Slut Maniacs 5 Female Teacher & Female Doctor Edition

I watched this for Kurara Iijima, but she’s only in it for about 12 minutes and stays fully clothed, so you don't even get to see her great body or butt. I was disappointed. The others were even worse. Aside from one teacher character who had a bit of a 'pervert' vibe, there was no sense of a female teacher or doctor, nor any 'older woman' appeal. Other than them wearing lab coats at the start, I have no idea what the appeal of this work is supposed to be.
