Hi ABigFan, glad you're enjoying the story and pacing. Bringing out Lara's inner whore is the direction I'm going in. At first, I was going the route of having Lara tricked into doing stuff - for example, the black tape modelling was going to feature a deliberate wardrobe malfunction. But I think it's hotter if Lara decides to do stuff - albeit it being manipulated into doing it.
The nude modelling in the next chapter, for example. Lara will hold out for 2 weeks, during which time she experiences the hell of being an actual maid. Then Sam says she's convinced Sarah to give her not only the day of the shoot off, but the day after she gets a full pedicure, manicure, massage and hairwash/style - basically hours of pampering. She wants it so badly, and her fans keep begging her for more, and Sam promised the photos would be very tasteful and artistic... And so she talks herself into it. And there is our slippery slope.
