Mia thought she was being sly, because Step-Daddy wasn't home, by taking off her diaper very carefully and sneaking to the toilet. Just her luck though, she comes back from the bathroom to find Step-Daddy sitting on the bed holding the diaper. He is very cross with her and pulls her over his lap for a long, hard spanking. When Mia's butt is bright red, he puts her back in the diaper as she sniffles and sucks her thumb.
