My cousin has to know

My second cousin regularly posts pictures of herself on IG in panties and she has a huge ass which obviously makes me horny. She's not blood so I don't think it's weird (I've also got a history of incestuous sexual behavior with my uh entire female family) but I drunkenly accidentally hit send on a text telling her I wanted her and I think she saw it before I could delete it from our thread. We've had sexual conversations before and I've confessed things to her that are disgustingly perverted and when I told her I was attracted to someone in our family she was like "yeah she's hot eh" and bit her lip. And I told her I have a panty fetish and she knows I'm gonna see that.
I just hope she lets me at that ass someday because god...even my wife and friends think I should just be a freak and go for her. Her ass is huge, her tits need specially ordered bras. Ugh...I'm gonna go jack off to her IG and wish her ass was on my face while I cum
