There's 2 large packages from Xnop73, around 700 MB, that were used only on intro 4 - Sex class. These package add other students in the classroom, which was only meaningful for that intro theme and follow-up sex scene, but to make better use of such large packages I added a checkbox called "Pervy mode".
If you want an audience regardless of it fitting the theme or not, there you go, toggle "pervy mode".
I received some feedback on the scene from another user who tried to change the female to a male or futa. This worked more or less, I didn't test it. If you do attempt to change the female atom to a male/futa atom, try to keep the height or scale to match the bar on the customisation area. On the pre-existing male atom add the anus target in the Divining Rod plugin.
Changing the pre-existing male to futa is likely no problem, it's the same base geometry.
