Personally, I like the colour contrast, nothing more, nothing less. But I'm very picky...the guy has to pretty dark and the girl pretty pale. I can't be bothered watching guys like Shane Diesel, for example (at least, not as 'interracial'). Black on Asian does absolutely nothing for me, and I love Asian chicks...same thing again with Latinas. Sativa Rose fucking a white guy = , Sativa Rose fucking a black guy = ...don't know why, that's just me.

I run a site (amongst others) that focuses on IR porn, so I get to hear a lot of what people like about that particular niche, and I'd say most of the reasons have already been covered in this thread. I don't particularly go for the whole 'superior black man' thing or the cuckold stuff, and to be honest, I haven't watched any IR or joined an IR-themed site for at leat 18 months, quite possibly more. Nobody's really 'doing it right', for my money, and to be honest, I've gotten rather bored with it.
