Today was pay day, the day of the week where her hopes were the highest, but her sense of potential disappointment was also high. The anxiety that made her stomach flip all day made concentrating on her job difficult, but simmering under that, keeping her committed to it, was the strange sense of arousal that came with it.
Financially she was doing well, a good job, a nice apartment in a nice part of town, disposable income to do the things she wanted. Then she met him, at the time just a guy on a BDSM message board, someone into control and denial. He lived on the other side of the country, it didn't stop them from playing remotely, exploring in ways that they could. For her, giving up control was always a thrill and giving him control at times was as much stress relief as it was arousing.
As she walked to her car at the end of the day, her heels clicking and echoing through the carpark, she tried to remember how the idea came up. It built over time, started as a fantasy and over several days they kept coming back to it and refining it, until it seemed like something that could actually happen. Not financial domination exactly, more like financial reliance on him, with her own money.
Each week her employer deposited her pay into a shared account with him. It required authorization from both of them before money could be moved out of it. In this way he could never "rob" her, she still had to authorize all movements and able to see where money was meant to go. Every night on pay day they would video call and he would decide how much was sent to her private spending account.
He couldn't see this account, it was hers to spend as she wished with no requirement to justify her purchases. This was the money she had to live on for the week, it would need to pay for food, drinks and any social/recreation activities for the week. She could ask more during the week, but it had to be justified, he had to agree and he would always extract a cost.
