What is to become of the Mills n Boon heroine?

Remember when she was some irritating lil chit back in the day who loved to hate the devastatingly good looking hero until he finally "undid" her with his kiss and they lived happily ever after? As in there was no sex in that book and they didnt even touch or anything...

Then in line with the times a couple of sex scenes were thrown into the books and the lil chit became independent and more daring...All very entertaining.

Then I got this mills and boon that I was reading last night and I was positively scandalised. The title has to do with something about becoming a Sicilian billionaires mistress...It started of ok with her being a cleaner in his office and he was tired of women throwing themselves at him so would he go to a dinner with him and be some sort of decoy...So that went well then he wanted to shag and she wanted to be fed before shagging so he took her to dinner. In bed he propositions her "will u b my mistress?". She didnt really front she says ok. Mind you this is the 1st ten pages of the book. the next 100 go on and on about their sex life and how he offers to buy her clothes...she resists VERY weakly (wat kinda MB heroine does that?) next he is offering her money she accepts with lil protest coz he gran fel n hurt her wrist so she needs a helper...then she wakes up one day decides she cant b a mistress anymore...he offers her more money she refuses, he is shocked til he realises he loves her and wants to marry her (this is in the last 2 pages) and they live happily ever after...That was positively pornographic...
