I'm a guy. I'd like that too but I'd like it to be me who fills all of her very attractive orifice. Impossible, but I'd settle for dildoing her while she gives oral.

Yeah that's right up there with wanting your wife to have sex with a dog

kind of strange.. you should introduce that demanding fantasy with a diamond ring / sports car / something of the sort

I don't think it's particularly odd. Influenced by watching lots of porn videos, yes, but not strange in particular. My boyfriend uses a dildo and finger on me while I blow him. It's easy to do if your wife is in the 69 position or something similar.
