The naughty knickers are a pair of knickers that are saved for very special cases.
And this girl is such a special case. She’s been ordered to wear the naughty knickers, in which her bare bum is completely revealed.
Her cutesy little apple buttocks stick out while she is being administered an otk spanking when she is over the teacher’s lap.
She gets a severe bottom thrashing, the likes of which she will not soon forget.
Better be on your best behavior, girl.
