Luke Harris is having a hard time fitting in with his new firehouse crew. He knows every time they see him, they think of the friend they lost in a horrific fire. As part of trying to build a relationship with the guys, he tags along one night when they’re letting off steam at their favorite club. What he finds there, shocks him to his toes. His new friends are members of a Memphis BDSM club.

While shocked, he’s also drawn to a D/s couple with exhibitionist tendencies who just so happen to be personal trainers in real life. So, when the fire department decides to improve the firehouses’ fitness, these two are contracted to provide physical training—in the station house. Anton and Britney make it clear from Day One that they have an ulterior motive for accepting the job—they want Luke. Now, everything he thought about himself and his sexuality is challenged.
