Mia's Masters (Locks & Chains #2)
Sara Kingston

Dylan Cooper and his partners Mathew Reed and Peter Burke have lusted after their sexy receptionist for years. But she has a boyfriend and they aren’t home wreckers. Besides, who could possibly accept three men, all with very strong kinks, into their lives forever?
They offer Mia their help. Honorable and not so honorable. With the hope of finally getting her into their bed. Just the way they like it, on her knees and ready to serve.
