mistressmystique - Over Teacher's Lap

You're caught under your teacher's desk trying to get a glimpse of her thin red panties. She discovers you, and tells you that you are in for a very humiliating punishment. You will be spanked over her lap in front of the whole class...with your pants down. You can't help but get an erection while being naked waist down over her lap for all to see, so you earn an even more embarrassing punishment in which the whole class gets to participate. Will you learn your lesson?
