Honey, any Plans for Tonight?

Non-nomadizing succubus of the Umbra type, also willing to marry and ready for palliative care until the end of life. Genetically improved and actually not only seemingly flawless. Highly intelligent, well educated and with a wide range of interests. Often "specialized" in corporate law, tax law, patent law, inheritance law, family law, criminal law, asset management, foreign exchange trading, real estate trading, stock trading, foreign trade, import and export, and anything else that might come in handy. Hobbies and sports are extra and would go beyond the scope here. Her preferred target is childless gentlemen of very advanced age who are willing to marry or adopt an heiress, without offspring, and other heirs with a less than rosy long-term health prognosis. Even as an existing or soon to be expected care case without guardianship, you can still expect to have a chance.
She is also interested in nouveau riche large companies, company managers who don't know what to do with their billions or are very risk-loving. Younger billionaire heirs are also welcome, whom she advises on legally compliant tax-saving models, naturally for a correspondingly high commission plus expenses and free board and lodging with a company car and credit card for spontaneous purchases. They also act as asset or insolvency administrators. First this way, then that way, then gone. Next...
The impression is not deceptive. If you get involved with Succubi, you get a lot for your money, which is actually pricelessly precious when you consider the incomparable quality of the miracle creatures. Standing at the end of life, sitting or even just lying down, with many billions in overseas accounts that you can't take with you when the big elevator goes up or down with you, you wonder what else hasn't been ticked off your bucket list. Unicorns to caress are hard to find anywhere, but Succubi are not something a billionaire has to search for. An advertisement in the miscellaneous section of a large daily newspaper at the weekend with the text "Dreaming of unicorns, 12-language travel companion urgently wanted!" is enough to make your wishes on monday come true.
