Open Question: Please help in this situation?

[feedcrawler]

So what I am 14 years old and my older sister is 18. We adopted her from my mom's cousin and so technically she is my second cousin. So I have a foot fetish and somehow I forgot how this happened but a long time ago I realized she had nice feet so we started playing footsie. I was really turned on and so over the years I have been playing with our feet and she was a really beautiful woman. Like literally she had a lot of modeling jobs but she all turned them down. Anyways, couple years after she moved in with us she we were alone in the kitchen and she started grinding on me and I do not know what to do. Since I am a guy I was really turned on and started masturbating about it. She had been the one who I was attracted to and I know it is really bad. So, she recently left the house and I'm left with this "urge". Please help me I know this is bad to me and to God. I want to better myself and need help!!!! What do u think?
