I have many fantasies (many of which have to do with being objectified or used) but one of the feederism related ones would be to submit complete and total control to a strong Dom (preferably a Daddy) who tied me up naked like an animal in a barn and had man after man come in and force me to eat and fuck or i'd get spanked or punished otherwise according. Then I would get pet and told what a good girl I was for being Daddy's little slut.
