Okay update so far: the option to ask Ste about the glory hole at night is gone now that it is made. I just had an encounter with 2 potentially new characters, too: Lenny and I think Ed..mund? Nothing bad has happened so far except eating out a rat.
Everytime you encounter the ones that you (and the mc) assumed it was Ste, it was actually a different horny minotaur.
(You might've forgotten (just like me) why Ste's here and he mentioned the minotaurs before.. or it was mentioned in a journey of his wife)
If you keep sucking their dick you'll lose sanity points, once you go insane there is an ending and you'll learn a bit more about them.
