Press Your Luck by Ajme Williams

Rules for dating your hot, much older boss: 1. Don’t fall in love. 2. Don’t meet his family. 3. Keep it light, fun and hot. 4. Don’t let him get you pregnant… Todd Marshall is my hot boss billionaire I’ve been semi-successfully resisting… until I fall into his lap at a wedding. Suddenly he’s no longer the intimidating handsome playboy who pays my bills. He’s a man I cannot keep my hands off of. I break all my rules with him. All hell breaks loose when his ex arrives in town with their grumpy teenage son… in time for me to realize I’m going to have Todd’s baby, too. Everything will be okay… I just have to keep this pregnancy a secret. Forever.
