Open Question: I am scared i may be obsessed with my wifes younger sister?

[feedcrawler]

for as long as i can remember, i have always thought my wifes sister was gorgeous. She's 21. Since i have been married, my obsession has grew, to the point whenever i masturbate or have sex, i think about her. Another thing is, i have a foot fetish, and i love her cute feet, and i used to always look at her fb profile, and when she put up new pics where she was barefoot, i masturbated and thought now that i have done so, i can relax as i have clearly seen what i craved so long, but this wasnt the case, i still think about her and get excited to the point i need to masturbate. I even tried secretly filming her so i could have something to masturbate to. How can i stop this? I will see her the rest of my life. Its been years now.
