My incest is not going as well as I would have thought and I need help.

My incest started about 2 years ago, but not in the way I want it to end up . I have 2 sisters: one 7 years old and one 11 years old. Yes, I am a 14 year old girl and I'm a closeted lesbian. I think about my sisters sexually and want a sexual and romantic relationship with my 11 year old sister . I know it is not a normal relationship and it is going to be extremely hard to be able to act on it once she hits puberty . I am currently grounded by my parents and I don't have access to my phone or computer after a teacher at school got a hold of a note I wrote to my sister . I know I am probably going to be in counseling now after this, but I'm more worried about how to work on this relationship without it backfiring. I feel like my only option is to act on it at this point. I am on r/incestsupport and I have tried reaching out to other incestuous couples and I have found a few people in my situation and they have been helpful and have given me some advice, but I still want to get more outside information if I have too. I know this is not going to be easy and I know there is a risk involved, especially with my family's background of incest and molestation. I know I am not the only one in this situation. <br><br>Some background on my abuse and why I am worried it might be considered molestation. I was sexually abused by my grandfather from the time I was 2 and I am aware that he is a pedophile and that is part of why my parents are overreacting now. I am also aware of my sister's past abuse and I know she told certain therapists that her grandfather touched her inappropriately in her groin area and that she is scared of getting pregnant by him. I am very aware of the past abuse and I am scared that my parents will think I am a sexual predator as well . I am not . I am conflicted and need some advice and reassurance.
