There's no boundary Zach Purser won't push. Three-ways, four-ways, sex clubs, he's tried it all. It's all about the freedom, but lately he's had the nagging feeling that something is missing. At his friend's engagement party, he spots the missing piece all tied up one hot little package of a woman. Trouble is, she's Adam's baby sister. Adam, his best friend, who knows all of Zach's dirty secrets. Which means if he even thinks about touching her, he's dead. Paige Clark has crushed on Zach since she grew breasts, but he's never so much as glanced her way. Until now. She knows desire when she sees it, and Zach's eyes burn with that unmistakable heat. Finally, she's got his attention—now if only she can get him to act on it. Zach tries his best to push her away, but she doesn't push back, she pulls—tumbling them both over the edge of resistance and right into bed. Panic isn't far behind. Now he's stuck between a big brother who'd like to bust his nose, and a woman who's gotten under his skin. And of all the things he's tried, romance isn't one of them.
