Noelle became totally entranced with her math tutor as soon as she saw him. Her parents expressed some reservations about him but he proved to be a great instructor. Little did they know he was going to instruct their little angel in sexual matters as well. Noelle easily seduced him while he was trying to reinforce what she already should've learned in math class. When a horny little minx like Noelle starts coming on to you there aren't many men who could resist. Especially when the alternative is behaving yourself and conversing about Pi. He was much more interested in her hair pie although she freshly shaved it in anticipation of the seduction. For them,  1+1= fun and cum.
