It's called marriage.

(The afterglow is called alimony.)

It is with a very heavy heart that I post this, as she seemed like a very charming woman when I met her, but I have it on extremely good authority that Mistress C of L.A. does not conform to the rest of our community's standards of ethical behavior.  A number of my trustworthy friends in the scene are seriously pissed off about getting burned by their experience with her as the organizer of the dungeon space at AdultCon, but the story that I heard that I feel compelled to pass along to TER is that Mistress C had a married client fly here to visit her for the weekend and then purportedly charged thousands of dollars to his credit card.  When the client caught her doing it, she purportedly threatened to tell his wife.  Mistress C makes a big deal about financial slavery as part of her services, but this was, most assuredly, NOT part of the client's scene.  This sort of behavior gives all honest BDSM providers a bad name.

Hobbyists, if you chose to see her, consider yourself warned.

Financial domination is HUGE in the internet world. I heard about it 10 years ago via a website I do phone sessions through. You'd think with my stage name Adora Cash I'd excell at this BUT I don't. Infact, one of the few things I don't excel at. This is quite a touchy scene and why I suck at it, unless its someone telling me to hang up and raise my minute rate on a phone session.lol
Its crazy, the things they'll ask for in financial domination, the information they'll offer, the extremes they want to take it but there are many that get off on it and I've read stories of extreme situations it leads too.

Financial slavery is a very real fetish for those that practice it. I think it has to do with men who really want to give up control of everything, including their finances, and get off on the worry and fear that what they have to offer financially won't be enough to get them the attention they need from their Domme of choice. To have to offer up more and more, desperate for the affections of the Domme, can be extremely humiliating for guys like this, and that's what they crave....to be told they are not good enough, they don't give enough, they need to give more.

I do financial enslavement, and even consensual blackmail, but I have a contract that my boys have input on, and I make sure that together we stick to the contract. I make sure I understand their needs out of the relationship, and I make sure they get them filled. Dommes who use it just as a way to get money, without putting anything back into the relationship, IMHO, do all pros a disservice.

It is an interesting study of the male psyche

Nicely said.  I think it's a fetish that's much more common among "trust fund babies" and others who feel some sort of guilt about having wealth that perhaps they feel that they didn't deserve/earn.  It's also common when someone wants to serve a Mistress long-distance, where they might only have a phone or webcam relationship, although that might tend to take the form of "gifts" (e.g., enjoying seeing your mistress wearing a special pair of high-heeled shoes that YOU bought her) more than financial domination.

but it is NOT something that should be entered into without both parties putting forth their expectations ahead of time.

In this particular niche, it crosses many boundaries that should never be crossed unless specifically requested.

I agree with anomalycutie.
I've only done it once but it was with the express understanding of both parties what was going on. It's not just "oh give me 1,000 and I'm going to ignore you from then on." There's a give and take between the fetishized humiliation and the donating, and egging the guy on and pushing his buttons in ways that he likes in terms being "forced" (quotation marks to denote that he isn't really forced because he agreed to it beforehand) to pay homage to a certain extent.

You are performing a valuable service is rarely done on TER--the site staking out a limit on acceptable and unacceptable behavior. Good for you!!
