On The Back. Lisa and Tina caper down the stairs to tape a large note on the back of the Headmaster’s jacket. When he leaves in a bit of a rush, he gathers his jacket and keys and heads out the door, oblivious. But when he returns you can hear the anger in his voice when he summons both girls to the laundry room, Lisa to bring a cane and Gina, a strap.. They claim innocence when he questions them about the note which reads “idiot.” Headmaster was thoroughly humiliated at people pointed at him and he did not know why until his friends informed him of the paper on his back. The girls lame excuses are not accepted and they are made to pull down their panties for punishment.. Riding piggyback, one on the other, they are punished with the strap and the cane on their bare bottoms until welts appear. When the headmaster is finished the mischief-makers are left without their skirts, hugging and comforting one another against the wall..
