Saras slutty outfits have finally landed her in the headmasters office. He gets one look at her tight black skirt and knee high boots and immediately orders her to lie across his lap for a good old fashioned spanking. He smacks her ass a few times over her skirt, before lifting it up to reveal a sexy white thong, which Sara knows is forbidden in this school. The headmaster spanks her round bottom nice and hard, turning her pale behind a lovely shade of red. He lowers her thong and continues to spank her bare bottom. Once this OTK spanking session is complete, the headmaster orders Sara to rise, pull up her panties and skirt, and return to class.
