This is the Complete Silken Edge Series containing all five books in the bestselling series.
From Book 1:
The relationship was over long before it ended, so when her boyfriend dumps her, Kristy craves a change in life. Kristy's best friend, Sherry, is into the BDSM scene, and on a whim and a bet, Kristy finds herself in the playroom at an exclusive club. A disguised Dom named Master Jay uses sensation play and a piece of silk to help her discover the world of kink. She finds it enjoyable and addictive, but what she doesn't know is that Master Jay is really Jake, a much younger man to whom she's strongly attracted.
For the past couple of years, Jake quietly watched Kristy in his gym. He doesn't care that she's older than him; he wants her. When the virgin BDSM sub he's hired to train ends up being Kristy, Jake almost falls apart. During the scene they play at the club, he fantasizes about getting her into restraints in his own playroom. But Kristy is shocked when she learns that the two men she desires are one and the same.
Can Kristy who's led a vanilla sex life, and Jake, who knows nothing but kink, find a future together?
