Hallo, I think I know what is was that Suzanna not like it.

I think it was what make to an torture and perhaps something that shock her. Perhaps it would help she could tell it Nina. I could also could happen something similar where the Mother can now turn it. That let return to idea of a burglar.
I hop only that both in end come to a conclusion that make both happy. Nina could lean she make Safe, sane, consensual and mother perhaps daughter have good friend how make the mother could trust him.
