I need this horror movie's name plz

So hi , years ago i watched a horror movie and i like i can't find it, i've searched for two years and nothing found. (I'm gonna describe what i remember so it may be not the real events ) The beginning : Like a groupe of teenagers decided to go to a friend's big house in winter to pass a weekend in think, they get reuninted and went there. The middle of the film : They arrive and enjoy the time with theirs boyfriends / girlfriends. Then like 2 thugs ( i don't remember if they escaped prison or what ) saw the house and decided to go there. They entred and started to violate and rape the girls in the house ( one girl is like a big religious and virgin, she did'nt even want do things with here boyfriend) Then started literally killing them ( i'm not sure but i think it is) so the groupe of teenager was in a fear and wanted to survive. I remember that one girl escaped the house and was took in a car that reget her in the house. So at the end we found out that the girl (owner of the house ) invited her friends to sacrifice them with her parents. Hope you can help me and thanks for reading.
