I got birthday spankings at school through 5th grade, always with the teacher's paddle. You were called up to the front of the class, told to bend over, except in kindergarten when the teacher took you over her knee, and got a light swat with the paddle for every year on your bottom, followed by a pinch to grow an inch.
At home, my birthday spankings were usually given with my mom's hand, over my clothes. Mom would wait until I had blown out the candles on my cake, then announce it was time for my birthday spanking, and told me to bend over. I would bend over, put my hands on my knees, then I got a spank for every year over my clothes with mom's hand.
Little did anyone who was at my birthday party know that it was my second, and sometimes 3rd birthday spanking. Every year on my birthday, until I turned 18, mom would wake me up, sit down on the edge of my bed. She would tell me to bare my bottom, and come over her knee. Then once I was over her knee, my panties at my knees, she would flip up my tshirt or nighthgown, and tell me it was time for my birthday spanking. then give me a spanking with her special "birthday paddle." It was one of those cute little souvenir paddles that used to be on sale in stores. Anyway mom would wait probably 10 seconds between spanks, and spanked with moderate force. These spankings left me with a warm and light pink bottom. They were special to me, since I saw these spankings as mom's way of reminding me to behave myself that year. I really miss that special morning ritual since leaving home.
I also got birthday spankings other places. When I took dance lessons as a kid, whoever had a birthday coming up the next week would have to go in front of the class, and everyone would sing happy birthday. Then you had to bend over and got a spanking with the teacher's hand on the seat of your dance outfit. It was nothing more than a light pat on your bottom for every year that didn't really sting much at all. Then when I was 16, my best friend gave me a birthday spanking with a ruler.
