I think fetishes and kinks all sort of depend on context. I can usually get behind most anything, with a few exceptions. That said, personally, I’m a fan of the slob, weight gain, humiliation, and redneck transformations myself. The ones I’m less interested in personally would be feminization, age regression, straight-forward muscle growth and straight-forward mind control.
Also, you’re welcome for the caption. I actually just had someone else ask me if I would expand the vignette even further, but no details have been hammered out on that yet, so we’ll see if that happens or not.
