Master David: A Service Submission BDSM MM Age Gap Romance

Rate this book
For five years, my only ambition was David Grant.

From the moment I saw him, a lowly intern in the empire he'd built, I knew my purpose. It wasn't to write code; it was to serve him. I re-engineered my entire life with a single to become the perfect instrument for his will, anticipating his every need, making his world frictionless. Now, against all odds, I'm his new personal assistant. He thinks it’s a game, a series of tests to gauge my competence. He has no idea this is a calling, and my submission is absolute.

He was a beautiful, fascinating puzzle, and I intended to solve him.

My new assistant, Tommy Flores, is a prodigy of service. He’s quiet, brilliant, and exquisitely obedient. He's also my perfect type. I decided to have some fun, to push his boundaries, to see just how deep his desire to please truly went. A quiet command on my private jet, a humiliating task in my office, an intimate "working dinner" in my penthouse… he passed every test with a beautiful, trembling grace.

But my simple game has become a dangerous obsession. The line between boss and Master, between assistant and pet, has been irrevocably blurred. I see the worship in his eyes, I feel his unconditional trust, and a strange, protective, and possessive emotion is beginning to take root.

He came to me to be owned. I may have just found the one man who could end up owning me.

The Assistant is a steamy, standalone M/M romance that delves into the heart of a powerful D/s dynamic. It features a possessive, dominant CEO, a devoted service submissive with a secret long-term crush, and a slow-burn romance that builds from the office to the bedroom and beyond. Expect explicit scenes, intense power exchange, collaring, BDSM elements, and a hard-won happily ever after.

Beautiful Service Story

I really love that this was a true story of service submission. I appreciated that after they started to fall in love and form a more romantic connection the service wasn't dropped. As someone who deeply appreciates a service submissive it was nice to see it be represented with care and grace. I appreciate the dynamic being treated with honor.

I do wish I could have seen more of them falling in love rather than just be told it happened. I did get a little frustrated at how little conversation I got to actually see them having between one another. This created a little bit of distance, for me, in feeling that I truly could see what they related on as people outside of their love of power exchange and service.

But the fact that there are so few books that truly represent service submission well, I can't do much more than be glad that this exists at all.
