I need a professional psychologist to explain the root of this, as it seems to be a common phenomenon
If purely sex-drive, as a fairly attractive woman (at least in the photos), she could easily find willing men every night, if she so wanted.
Is it laziness - simply being around these children/teens every day has attracted her to them?
Or is it deeper - some kind obsessive desire for control over people “beneath” her and in her control?
I think that you are close; I’d bet she is a BDSM practitioner who got a thrill out of the control aspect.
