For real advice. Not the blanket porn crap.

I'll admit. I have an incest fetish. I've never participated but have yearned for it my entire life. My wife allows me to fantasize and we talk about it periodically. It's super fun and i / we love it. Now for the advice... my EX wife. As terrible as this is, we still dirty talk and send pics back and forth from time to time. Our relationship was incredibly toxic but the sex was amazing. And we dabbled in hotwife activities, sugar daddy, her doing porn, among others. Several years before we split she got fake boobs. They're, well perfect. It's hard not to notice them. Plus she dresses to show them off pretty much all the time. She's very vain and loves attention. So last night we were texting and somehow it came up that we both had noticed her dad looking a time or two. She sort of played into the fact that it turned me on but was a tad resistant. However she did say that she definitely likes the fact that she's "so hot" that even her dad couldn't help but look. I don't want her or anyone to do anything they aren't comfortable with. But I do believe she secretly, or maybe subconsciously, wants more with her dad. How could I, or really even should I, encourage her and help it happen if she does in fact want it?
