I like the premise behind the story but there are a few things I feel need mentioning.
Firstly, you really need to make use of spellcheck because there are many errors. You also really need to brush up on the punctuation. Typically little mistakes don’t bother me but they seem to be running rampant and distract from the story.
Secondly, you should try breaking up your story into paragraphs. This will make it flow better and easier to transition between different parts of the story.
Thirdly, I think that you could have made the good twin seem more desperate. The story is lacking in any intensity. Put some effort into the description of the good twins thoughts and that way I think it could be more gripping.
