Here's a bonus episode of a new show from Pushkin, Other People's Pockets.

Have you ever wondered how your friend bought that vacation home or why that colleague of yours makes everyone meticulously split the tab down to the last Diet Coke? Other People's Pockets is a show about other people’s money. Host Maya Lau asks people from all walks of life to get radically transparent about their personal finances in order to learn more about who we are and level the playing field a little bit along the way.

In this episode, Maya sits down with Mistress Marley, a financial dominatrix who makes money from people whose kink is simply giving her lots of cash, without being physically touched in return. Hear more from Other People's Pockets at https://podcasts.pushkin.fm/opp?sid=wyp.
