In a sultry Brazilian classroom, a mature professor, a married woman with a reputation for her insatiable appetites, teaches her husband a lesson he won't forget. She's a 'santinha,' a saint in public, but a sinful seductress behind closed doors. Dressed in her prim school attire, she teases him mercilessly, her 'nova' and 'gostosa' curves driving him wild. As she whispers her naughty desires, her husband can't help but succumb to her 'nova' charms.
