Kissing the Rival by Kaylee Ryan

I’m not just kissing the rival… I’m falling for him.
Spencer Pennington has always been a shameless flirt, but when it came to being the best in our MBA program, all bets were off, and the competition was on.
Fast-forward a few years, and all it takes is a bar at a failed wedding and my silly kiss-rating system to lock lips with the enemy. Cocky as ever, Spencer claims he’s a ten and kisses me to prove it. I kiss him back to scratch an old itch, not expecting to like it.
Which is a huge problem, because Mr. Tall, Dark, and Tattooed from grad school is my new boss. And I want to kiss him again and again. Even if I only gave him a four.

Charlotte Krause could be the perfect girl, if she didn’t hate me so much. I’m unsure if it was just me or guys in general, but she had this stuck-up, all-work-no-play vibe about her in college.
Imagine my surprise when I find her at the resort bar rating kisses like it’s her job. This carefree woman is nothing like the focused girl who turned me down at freshman orientation. And every time after that.
When I promise her I’m a ten, I see that competitive spark light in her ocean-blue eyes. There she is. She might have kissed me to prove me wrong, but I know I’m right about one thing.
She feels the spark too. There’s just one problem. It turns out her actual job is working for me.
