WANZ-622 - The Tragedy of a New Female Teacher, Gang-Banged by Students

It's exactly what the title says, but the premise is so forced that I couldn't get into it at all. Why not just go with a normal high school girl setting...?

Himekawa Yuuna has a baby face... I get that's her selling point, but even for a first-year teacher, she looks way too much like a high schooler. For occupational themes, you need a sense of realism to make the 'corruption' aspect actually arousing.
