Lucie’s punishment seems reasonable enough at first. After all, she’s been caught behind the bike sheds again, and she has to learn her lesson somehow.
Perhaps the Headmistress’s choice of skirt should have been the first clue that her motivations weren’t entirely wholesome. If not that, then surely being ordered to strip down to underwear and bend all the way over – surely that can’t be regulation! Then of course she’s teased, scolded, touched, exposed…
…all in all, there’s something a little risqué about this particular teacher/student encounter. And whatever does the Headmistress have her phone propped up like that for?
