Emberline by Lilith Ember

Finn Calder has three rules for private-club contracts: keep the tools clean, keep the secrets cleaner, and never stay past the final invoice. The Emberline—an exclusive members-only men's club of brick, black steel, and carefully bought silence—breaks the third rule before he finishes unpacking.

Hired to overhaul the lighting and privacy systems on the private upper floors, Finn expects two weeks of clean work and a quiet exit. What he finds instead are the club's two owners: Rhys Thorne, controlled and intense, silver at the temples and gray-eyed; and Mateo Ruiz, warm, filthy-mouthed, and built like the training floors below. They make the offer clear on the first night—work stays work, but after hours are theirs if he wants them.

He wants them.

What follows is a continuous, uncensored MMM claiming: oral, anal, double penetration, spit, sweat, and the kind of possessive heat that turns a two-week contract into something permanent. Finn finishes the job. Then he stays—because the systems are clean, the suite is his, and the two men who own the silence of the upper floors have already decided he belongs between them.

Why-choose. High-heat. No fade-to-black. He stays.
