Ossa has been gifted with an at-home fitness session thanks to her sweet son. She selects the boot camp option having taken those kinds of classes before and liking the challenge. When Sergeant Sins shows up at her door, it quickly becomes clear that this isn’t a regular boot camp course and Sergeant Sins is no regular instructor. He puts her through all the physical paces and challenges her to take her fitness (and sex) game to the next level.
