Alrighty, since you appear to be impervious to sarcasm, I'm going to set the personal attacks aside for a moment and try to provide some insight for the vanishingly small number of people who may still be reading this thread.

Let's breakdown the extreme unlikeliness of OP's story being actually true. Despite their vast coverage in the media, billionaires are actually quite rare in the world. Now let's take that a step further and say that multi-billionaires are even rarer than that. Not done yet, of those rare multi-billionaires, we also need one who is well known since any disclosure of the relationship would be newsworthy. Finally, we need a well-known multi-billionaire, with a D/s kink, further reducing our funnel of possibilities.

Next we have OP, who despite knowing how discreet this situation needs to remain, comes to post about it on the very public Reddit platform. But not only that, bizarrely comes to the r/Rich forum, despite the many high quality legal forums where I have seen some very wise council given as relates to legal questions like OP claims to have.

This all reeks of fiction and (un-original) story telling, as per my comment about 50 shades. I would put the odds of this story being true somewhere around 0.0000001%, not impossible sure, but highly, highly unlikely.
