Name of a horror movie

I once seen a movie but i remember only the opening: a girl is tied up in a house with her breasts exposed and a man with a knife touches her can anyone help me find it?

Thankskilling. Next question...

@thekramer89: Nope

Ummmmmm. Any late seventies early eighties horror movie. But it may be I Spit On Your Grave. Or maybe Straw Dogs.

edit: last house on the left?

That description is kinda way too vague.
