The third and fourth arms grow out of that single desire to hide sensitive areas.

It may be old-fashioned nowadays, but in some cultures, people hide their faces (to prevent being identified?) even when sensitive areas are fully open. I think that if we could specify where to hide, additional arms would grow to scratch the itch of the users.

Can this work with panties, or was it only trained on full nudity?

Thanks! It works with realistic models too
