This is a story about a girl who is infatuated with a sadistic man and asks him to accept her as his slave. She may be a friend of his daughter/girlfriend/neighbor. He doesn't think she's serious so jokingly asks her to cut her little finger off as a proof of obedience. She is trembling and crying but picks up a knife and tries to cut her finger off. He stops her and accepts her.
Does it ring any bells? TIA
It can be here, it can be in asstr. I read it about 15-20 years ago.
