The chalk squeaks across the board, leaving behind a trail of numbers that dance and intertwine like lovers in a passionate embrace. As Doncoligoro's voice drones on, his words transform into whispered nothings, his hands moving with a rhythm that belies the filthy thoughts racing through his mind. The classroom, once a sterile environment, now pulsates with a primal energy, the air thick with the scent of chalk dust and unbridled lust.
