I think, actually, her kink - as it were - is somewhere between humiliation and gang bangs. I'd guess, if she were more self aware of her desires be interested in humiliating her female characters (forced sex, being 'used' by multiple men, unable to control your own orgasms/sexual desires, public sex, potential forced pregnancy (merry)). She clearly loves the idea of a woman being service multiple times, by multiple men - some of whom the woman doesn't chose. Her sexuality is not, by my standards BDSM, but swinger. Swinger lifestyles - you milage may vary - are hugely woman focused (everyone is interested in sex with other women, women are expected to be sexually interested in all men, no male homosexuality takes place, lesbian sex is there to be observed by the men etc), very straight and aside from woman swapping, multiple sex partners, very vanilla and her work strongly reminds me of that.

But what angers me most, and makes me despise not only the characters but the author who came up with this situation is the author's refusal to look at what she's doing and simply remove any responsibility for the situations the characters find themselves in by using stupid deus ex machina like the aurder or the royal pregnancy bullshit line. She's not only stripping the characters of an shreds of respect but presenting a very unhealthy sexual lifestyle where 'true love' is used to excuse really crappy situations, magical date rape drugs are okay and whoring oneself for power is okay but whoring oneself for money is not.
