Professor Magnum has called his student Katie Zane into his classroom after hours to tell her that she's been tapped for an advanced, double-secret sign language group to which only a few select students belong. He shows her three suggestive signs, and tells her that they will only help her through the class and her future studies. When he asks her if she wants to practice, Katie nods and gets on her knees while her professor unleashes his hard cock, ready to go in her mouth!
