Impure thoughts about my father

I am 20 years old and in my 3rd year at the university of port harcourt. My parents asked me to move back home since they did not want to pay for my lodge again
After I moved back of i started having impure thoughts about my father. I am too shy to say anything to him or ‘make a move’. I sometimes forget to put on a bra and close the top button on my blouse so he can see my nipples Sometimes when Masturbating, I imagine my father fingering me.
