Momcest and feet are my two biggest fetishes. It's hard for me to tell which one is bigger, but when I masturbate to one I usually am also masturbating to the other in some fashion. Unfortunately, there's not a lot of good momcest-foot content out there (to my taste, anyway), so a lot of it comes down to imagination.
I of course don't know how either fetish first came about, though I think I was aware of my foot fetish from a lot earlier, even if it took me some time to put it into words. I can remember being interested in feet at age five, though whether it was really sexual at that point I can't say. On the other hand, my first momcest fantasies (some of the only ones to really involve my actual mother) were around the time that I started puberty, maybe fifth grade, though I wouldn't say it really crystalized as a bona fide incest fetish until a few years later. I don't have any strong memories of my mother's feet that I might have imprinted like >>81676706 suggests, though later on I thought sexually of her feet. So, I don't know if there's any actual connection, psychologically or whatever. In the end, >>81673742 is probably right.
Sorry for the autism. Thinking about my fetishes and why certain things arouse me is the only time I really get this way, for whatever reason.
