Erin's Story. The A-Z of Trophy Wives, #5

They're young, beautiful, with fast cars and luxury homes-with absentee, older husbands. Bored and lonely, each of our trophy wives has her own solution. Erin's husband is a close friend and political ally of the mayor, who is up for re-election. At the fundraiser at a local art gallery, Erin is stunned when her husband bids a fortune for the artist, who happens to be the mayor's son, to paint her portrait.
She knew it was a tax-deductible way to fund the mayor, but the expansive gesture brought a blush to her face. Unfortunately, or fortunately, depending on your point of view, for Erin, the artist had seen her blush, and knew that was the color tone he wanted for the portrait. When he wants an off-the-shoulder look so Erin can't wear a bra, she's embarrassed but goes along for the sake of her husband.
As the sitting progresses, Scott needs to get Erin to blush more and more. As his outrageous methods become more and more overtly sexual, can Erin see where the line between embarrassment and seduction should sit? Or have they already crossed that line?
