My opinion?

"Hey little student, I'm a ten foot tall bug-eyed monster. Why don't we go look for the nearest bar and have a beer?"

Aside from that, I am not a fan of using pacifiers to gain a student's compliance or complaisance to the idea of being raped. Tricking them into placing them into a location where they can be used in peace is one thing. Dulling their objections or their ability to struggle, or their horror at what is about to happen comes rather close to making it consensual and we have space locations where that can be played out.

El used to make awful prison wine!

In the toilet bowl? Say it isn't true!

You mentioned sake, which is basically rice and yeast: would mead be feasible, since that's honey and yeast? Obviously with the "blessings" of our benevolent slimegirl.

Just because it can be made doesn't make it legal.
