one story is old - The panderer by CeeCee I think, a UK writer. A woman is seduced by a sheik and flies on a plane to an island.
The other story is about a couple that gets insider trading info from an old friend about an initial public offering of stock and can clean up but have no money. The friend agrees to give the money if she will attend his bachelor party. He kidnaps her and takes her passport and there is a lot of sex the husband sees by phone or DVDs
