birthday spankings

My favorite day of the year is my wife's birthday. Not just because I like celebrating the love of my life and giving her presents. But it's the day I'm guaranteed the chance to give her a birthday spanking.
You see, I'm a spankophile. She's not. She'll indulge me everyone once in a while, but there's no arguments on her birthday.
In a few days, she'll turn 30. A nice round number and a good long spanking will commence...
