Jade Bleu 
Bought by a Billionaire 2: Naughty Nadia on Display (Bedding Billionaires, #3) [EPUB ebook] 

I was put on an art pedestal in the naughtiest position imaginable! 
It was my prodding—and my camera—that got my friend to sneak onto a billionaire’s estate and take pictures of him. After Jackson caught and punished her, he decided I deserved the same—but with a twist. I would be presented as part of his private art showing, with my back end and every other orifice fully occupied.
An erotic short featuring sex with a billionaire, exhibitionism, and multipartner fun.
