>rape

You need to get out more and talk to people and meet others. Stop watching incest anime . At 17 you're still in puberty and hormones are going crazy so while it's not good, it's understandable that if the only female around your age was your sister you would have these thoughts.

Alright, then my answer is still get out of the house and be with friends that are not your sister, to clear your head. It's possible she's been your support for the issues with your gf, and as a result you're transferring your emotions onto her? Stop creeping on her. She's your sister and she looks up to you to protect her.

>what do

You don't do anything. They're just fantasies. As long as you don't act on them, it isn't immoral to have those thoughts. We all have weird things we get turned on by once in a while. Try not to be ashamed of it and keep it pushing
