JM Seaborn
JM Seaborn is a large writer (physically, not in popularity) and occasional audio porn producer who has a fascination with romance and power dynamics in filth and uses a D/s couple he created to explore it all.
He has a little website (in popularity, not physically) called Written in Kink and a podcast of the same name, and he contributes to the Girl on the Net audio porn project. He also improvises short-form stories on X (Twitter) but probably shouldn’t because, well, it’s X.
