Somebody Like You by Heatherly Bell

Brooke that girl is entertaining, "how pathetic would it be if someone caught her staring at his ***? “Quite a view, isn’t it?” Billy asked. Oh dang, busted. Wait. Was he now complimenting his own ***? Aha! He was every bit the conceited jock." The conversations Billy and Brooke have:
                 “I get it. So you’d rather not run into me when I’m all sweaty and half naked?”
                  “No, that’s not what I meant.”
                  “You do want to see me sweaty and half naked?” He grinned. Evil, evil man.
                 “No! That wouldn’t be appropriate.”
                 "Says the woman who walked out the front door in her panties.”
I loved this book and the characters.
