If you can't stop thinking about one man, get under another. A scorching hot one-night stand with her ex Gabe and his current lover was just what Callie needed to start her recovery from a decade-long sexless marriage. One night only, because anything more than that with the man she'd never quite gotten over would be too dangerous. And the threesome was even more fun and filthy than she'd fantasized it would be. Now Callie's supposed to be moving onto new erotic adventures, without Gabe. Or thoughts of Gabe. No Gabe, damn it. But somehow her ex keeps getting caught up in her plans, and Callie can't make herself say no when Gabe offers to accompany her—strictly as her platonic safety-measure friend—to a BDSM club. Callie's trying to be smart, to protect herself and explore this fascinating new world at the same time. And she does actually feel safer knowing Gabe is close when Alejandro, the sexy Dom she meets, introduces her to her first experiences with submission. But when Ale picks up on the ever-present sexual tension between Callie and Gabe, Callie's going to learn just how far an experienced Dom can push two people who aren't sure where their boundaries lie.
