I knew a white bitch in middle school that would suck dick in the back stairs for lunch money..sad part is lunch was only $1.50!!!
That's very hot, at least if you replace 'middle school' with 'high school'. Women can make a lot of money selling sex.
Also know a broad that had sex with two brothers and their father at different times, but never involved in a relationship with any of them.
I would probably be turned on by a woman who admitted to having wild, hot sex with her brother or being attracted to her father (not that I think even consensual incest between adults is a good idea in practice but still, the idea is exciting). I've always wondered if there are people who are attracted to or regularly fantasize about having sex with family members they were raised with but I can't see that being the norm considering the Westermark effect. I'm not turned on by the idea of having sex with any of my family members, though
(I don't think the idea of having sex with my daughter has ever appealed to me).
It might be semi-off topic but I don't think men have a biologically ingrained instinct to avoid promiscuous women as long-term or romantic partners. I think it's probably a cultural attitude that originated with the rise of agriculture and by extension private property and the desire to ensure paternity through either polygyny or monogamy. I could be wrong but I'm more turned on by sexually adventurous women. Not that I would fault someone for being more sexually conservative.
