Customer Satisfaction (Lucky Springs Series, Book Seven) by Cheryl Dragon

Keeping customers happy is Lizzie Bouvier’s job. In public, she’s everything a sweet Cajun woman should be. However, in private, she likes things a little bit rougher. Her two hot boyfriends have been doing a great job keeping her satisfied until one steps out of the triad. Not willing to give up, Lizzie pursues an attraction to the Stinger brothers, two of her sexy customers who just happen to be dating her ex-boyfriends. The bigger the group, the hotter the sex, but they have to sort out the rules, commitments and past before things can move forward in a truly permanent group relationship.
