How exactly can one induce a fetish?
It seem totally random and simply talking about it every day doesn't seem to do anything.

Fetishes have a chance to increase each time they are triggered/called and that increases per the number of times they are called a day. For example, if you want to increase the incest fetish, taking a series of incestuous actions prior to discussing it with the Slave will increase the chance of it increasing their fetish level.
