I would say L. A. Wicker and James_Steele. Both have written stories which have edginess that matches with Klrxo's, not the long descriptive sex but tension and seduction throughout the their stories are really very good. BTW, Wicker has stopped writing long ago(no idea what happened).

Not entirely submissive kind of thing. But very well writte slow burn seduction with cucking element.
