I think it's great that there are plus-sized sororities. It's good that these women have their safe spaces. That being said, I think it's a bad idea to have a fetish-based sorority. The moment you make things sex-based, things get really messy really fast.
It doesn't matter what the fetish is. It will end poorly for everything - and probably turn into a brothel with the members being abused and trafficked.
