Tax season isn’t considered the happiest time of year, but if the person crunching your numbers happens to be our Coed of the Week for December 24, 2009, it definitely will be. “We girls look so professional and buttoned-up, but there's a sexy surprise underneath the business suits!” says all-natural Shayna Taylor. The petite brunette attends Florida State University where she is an accounting major, a temptress and an avid party girl. “There's always a great party going on—too many to pick a favorite,” admits voluptuous Shayna. Our favorite parties are definitely the ones whose invitation list is made up of Playboy models.
