I assume she simply had some kinky impulses that has progressively begun by unfolding themselves out overtime (or has always been in the closet) , and that the
want to mold herself to the societal norms has subsequently eroded off overtime.
Which, combined with a variety of other factors such as the mainstream Curvy/Plus Size modelling industry whose managers does reportedly encourages/coaxes its employee models to forgo significant dietary intakes and weight fat cultivation in order to get increasingly booked the bigger they get (in a way nowhere any remotely far from the chain of practises undergone within underground white-owned feederism catering adult entertainment platforms such as BigCuties or Stuffer31 performs for decades) ; the addictive intricacies of comfort eating in a highly-sttessful and competitive society, the euphorically freeing, let alone
titillating sensations accounted by some of those mainstream Plus Size models (as well as both regular women and feedees alike) while experiencing a significant weight change and sensing their bodies transforms a little further into or even past the buffer zone between of the thin-centric norms and the new demarcation lines for what appears "too fat" or "gross" in society with all the physical and mental perks and cons of those leaps into deeper lenghts of obesity; the subcultural impact of the whole Body Positivity movement onto women; sociologically well-documented plethora of evidence that both many African and Afro-descended communities holds centuries or millenia-old traditions of high regard toward pleasantly plump and heavier women, feeding and body fat cultivation; and at last, the fact that because of the latter factor, black people in Africa, the West Indies and U.S.A. did turn the once-marginal BBW/Feederism porn platform into the highest-grossing adult entertainment platform since the mid-2010s (according a survey done by Pornhub) renders social media commodity fetish creators - a breed of women who reputedly lives up for easy money, celebrity, clout and even sometimes for the geniunely clever ones a means to build up some hustle put of it - with a long backstory of having their content been dropped by their fans on the likeness of the controversial Curvage (thanks, no thanks
) or StufferDB, might every once and while leads up all naturally into such course of events chaining up.
Besides, if she already had an eating binge disorder prior making a way into the Plus Size modelling industry and that a quarantine-enforced lockdown enables her to more frequently stuff herself ravenously at home with little physical activity, it does help.
