Their Master Don [Gay BDSM ménage romance]

Master Donald is well known for being a hard-core Dom at Club Stunhz, but what his many admirers don't know is that he doesn't want or need a full-time Dom/sub relationship.
When Mitchell is attacked and badly injured by one of the Doms, the last thing he wants is to be ordered around by "The Mastodon," but since going to the hospital isn't something he wants either, he has no choice but to accept help from the huge man. Thankfully, Mitchell's friend and fellow submissive, Riley, is a doctor and can save him the embarrassment of trying to explain his injuries to someone outside of their lifestyle.
Riley has been hiding his professional personality behind bizarre hair color, outrageous fetish gear, and thick eyeliner. He has admired Master Donald for a long time, but has never found the nerve to explain that they know each other outside of the club. But when Mitchell is in need of emergency medical treatment, he has no choice but to reveal who he is.
Having two submissives living in his personal space is much more appealing than Donald ever expected. His attraction to both men is off-the-charts hot, but they're both subs and he doesn't want to be a full-time Dom. Maybe hot sex is the best any of them can hope for.
But what happens when the attraction refuses to fade? Can Riley be a full-time sub to a part-time Dom? And how will Mitchell react when he finds himself falling for the real man behind the Mastodon image?
