I've been late to class a lot this week, and the professor asked me to stay after. In order to keep my grades up, I agree to accept his punishment. I spank myself for every day I've been late, first on my ass, making it nice and red. To my surprise, the professor tells me to pull up my shirt and spank my breasts and sensitive nipples next. Finally, I pull my panties to the side and give my pussy a few spanks. I'll never be late to class again!
