Hahahah. It amazes me that there are people who still believe that she is, or was ever a teacher in her real life.
The naivety never ceases to amaze me. The whole "being a teacher" thing is part of her character. 100% fiction, like everything else.
She keeps her mask for two or three reasons:
1.- She wants to remain as anonymous as possible. It's hard to have a normal family life when you're in porn.
2.- The mask is already part of her character.
3.- The mask covers the ugliest parts of her face (weird nose, cheekbones and huge crow's feet). That mask makes her appear prettier and younger than she really is. You only have to look her in that few videos where her face appears by mistake for some seconds to realize she is not exactly gorgeous.
I think she would only remove her mask if money starts to stop coming in to try to keep the business afloat.
She started wearing that mask when her faceless videos stopped generating that profits.
And later, she started fucking other guys when videos with her husband started to get repetitive and boring. It's all about the dough.
