do you think you'll ever add other fetishes or have the MC change?
Other fetishes: yes, I plan to add many different MODIFICATIONS! What gets implemented next is normally voted on by my supporters.
MC Change: While I really like the idea of changing the MC, there will probably not be anything major for now. Maybe some scene will have like a - dick gets bigger - moment or something, but right now Mia is planned to be the main focus of the MODIFICATIONS.
