In Katharine Cane: Training Day 4, there is one last detail of Katharine's training that has to be addressed, and that is learning to service a male dominant. She is tested on her cock sucking skills and then given ways to improve them. She is then sadistically manhandled and fucked into submission. She is suspended with her legs spread wide, and brutally fucked again before her ass is pounded hard and fast and she is brought down to complete the day by paying off a debt that is owed to Derrick! Cast: Katharine Cane, Derrick Pierce
