Developing new erogenous zones

Lately I've been thinking about the possibility of conditioning someone to develop new erogenous zones. For example, a dom with a foot fetish conditioning their sub to derive pleasure from having their feet touched. I feel like any kind of repeated exposure to a stimulus in a sexual context has the potential to make it become erotic, but I also like the idea of doing it in a more deliberate manner, e.g. forcing orgasms on someone while stimulating the target area and exposing them to relevant images. Has anyone developed new erogenous zones this way or induced it in other people? Or just like the idea?
