This sort of reminds Edward's story

And looks like Maria is even more masochistic. :)

It is only beginning so nothing much to comment or suggest but everything looks good so far. I am waiting to see how he will use all those tools and how our masochistic Maria will react.
maybe I could suggest to place mirror in front of her so that she could fully enjoy the view of being butchered ;)

maybe if she is going to die there is no point for the rapist to wear mask it is not like she can recognize him later LOL

Your mistakes are almost in visible ;) but story telling is a bit plain. Maybe because of language issues.
