Mal has been Burke and Darby's sub for many years. As an undercover cop, he needs the release his once a quarter visits give him. Burke and Darby get a lot of out of the visits, too. Both Doms, it's important for them to share a sub now and then to keep them on an even keel.
All that changes, though, when Mal is shot on the job and needs to stay with Burke and Darby during his recovery. Can his Doms bring Mal out of the funk his last undercover stint has left him in? Or will the three of them finally go their separate ways?
