physically attracted to my Cousin

I am M29 and have a cousin of similar age as mine. She is a bit bulky but have a pretty sultry physique. I have developed sexual feelings towards her. I have confided my feelings towards her, to she didn’t mind it but asked me to hold onto them a bit as its not the right time. How can i convince her to have sex with my. I daydream throughout the day as we both having sex.
Suggestions please !
