At His Mercy by Claire Thompson

Intense. Exclusive. Invitation only. Do you have what it takes to be a pleasure sub?

Masters Club, a private BDSM venue for serious players, is perfect for Dom Cameron Lord, who gives the kink lifestyle everything he’s got—except his heart… When he witnesses a lovely sub girl enduring a botched scene at a NYC public club, he sees her potential. She’ll make an excellent addition to the Masters Club. But as he steps closer, he recognizes her…and all bets should have been off.
Aspiring young attorney Jess Cooper gets her release at the BDSM clubs around town, where she enjoys letting her inner sub fly. There’s nothing better than to be naked and bound, a stranger in black leather behind her wielding a whip. It’s the perfect anonymous relief from a stressful workweek. Until her worlds collide when Mr. Lord, the super sexy partner at her firm, watches her from the sidelines.
Any hope that he hadn’t recognized her with her clothes off vanishes the very next day at the office. No, he doesn’t say a word about what he saw. His invitation says it all…
