Am trying to separate what the "norms" of BDSM are from the idea of a fetish. Ropes, cuffs, floggers, toys and such seem to be a part of what is accepted as a form of dominance or humiliation. So, beyond those, i'd have to say my fettish is being milked. Not just being a Hucow, but just the joy of knowing Her Dom/me feeds from her.. the ache of waiting for the feeding, and even milking during the day to keep my breasts full.
