Their Master Sam [Erotic BDSM gay ménage romance]

Sam has owned Club Stunhz for six years now, and he takes his responsibilities very seriously. He’s always hesitated to get permanently involved with a sub for fear that he would need to set the man aside while he deals with the day-to-day problems of being the Dom in charge.
Jamie fell for his Dom a long time ago, but when he realized Master Sam was unlikely to return his feelings, he stopped visiting Club Stunhz.
Camden is fairly new to the lifestyle, but he’s relieved to find a place where his fetish isn’t considered unusual, a place where he truly belongs. When he catches the eye of the most sought-after Dom in the club, he’s thrilled by the man’s attention.
But Sam's session with Camden reminds him of the relationship he’d always dreamed of having with Jamie. Determined to find a way to claim a permanent sub of his own, Sam tracks Jamie down only to find Camden working in the same damn office.
Stunned by the realization that the men know each other, Sam wonders if that might be the answer. Can the three of them have something special together, or will the stress of building such a complicated, full-time, three-way D/s relationship destroy them all? It certainly doesn't help when a sub is attacked by an out-of-control Dom inside Club Stunhz or when Sam's brother, Daryl, is involved in a car accident that seems to be a targeted attack.
