Cleo enjoys being spoiled. Over the years, she has amassed quite a collection of gifts. There's jewellery, designer shoes, perfume and cash deposited in her bank account - all sent by devoted admirers. But she's never met any of them.A financial dominatrix, she makes money issuing orders to wealthy men, who contact her online asking to do her bidding. Her dozens of clients - who she calls "pets" or "pay pigs" - range from high-powered executives to suburban husbands.Relationships vary: from one "pay pig" sending £20 a week to another donating his earnings and having her take full control of his finances.There are many fetish websites on which "fin-dommes" tout for business. Goddess Rosalie von Morelli advertises online for "money slaves", selling her services to men who pay for the pleasure of receiving her orders."Domination, that's what they want," she said. "I send them messages, rules, goals, set them dates to treat me, spoil me, send me gifts or money."Cleo, 43, said: "I have clients who randomly feel the need to spoil a woman and others who want to be dominated or humiliated and have me control all their spending."Psychologist Mike Berry is not surprised by the dynamic: "It's to do with power and control. Often these men have high-powered jobs or their lives are very ordered, or they are sexually inadequate. The fix, the thrill, comes from handing responsibility to someone else and embracing the risk. It's a total contrast from the rest of their lives."Goddess Nia, 25, a full-time fin-domme in the US, said the more high-powered the client, the greater his need for humiliation."They feel enslaved by their companies. They want to release that."These men give me their credit-card details and call me on the phone just to have me answer and ignore them. I neglect them all," said Goddess Nia.It sounds like easy money but fin-dommes insist there is skill in what they do."You need to be a good reader of people and to know exactly which buttons to press," said Cleo. "I see what I do as an art. Working out how to dominate someone financially and emotionally gives me the real thrill." ..
