Both of Us Are His by Nicole Jackson

I never wanted a rival. I got one anyway — and then I got a lot more than that. Six months ago, Wren Castell walked into the marina office looking for a job. She got the last one on the property: dockmaster's assistant, which meant sharing a single-room apartment above the boathouse with the only other person who'd take it. Me. We hated each other for exactly nine days. Then Callum Reyes bought out the marina, inherited both our contracts, and informed us — with the kind of calm authority that made arguing pointless — that neither of our jobs was safe unless we found a way to work together. He didn't know what he was asking. He didn't know that "working together" would mean learning every place Wren goes quiet, every place she pushes back, every place she's soft when she thinks no one's looking. He didn't know I'd start wanting to know those things on purpose. He definitely didn't know he'd end up wanting both of us. I told myself it was a job. Wren told herself the same thing. Callum stopped pretending it was anything else the night the three of us got stuck on his boat in a storm, one cabin, one bed, and no more room to keep lying about what this had become. Now it's not about who he picks. It's about whether Wren and I can stop circling each other long enough to admit we don't want to share him — we want to keep him, together, and keep each other while we're at it. He calls us his. We're starting to think that's not far off. Both of Us Are His is a standalone Forced Proximity Reverse Harem (FFM) Erotic Romance with a guaranteed HEA.
