Mother helping son to get better grades

Aaliyah just got a phone call from her son's school, if his grades don't pick up they are going to kick him out. Aaliyah is pissed and confronts her lazy son, who is watching TV. She demands that he get his book out and study this very instant! When he refuses she does the only thing she can. She knows that she has a hot body, she catches him looking at her from time to time, and she is almost sure that he masturbates to her. For every right answer he gives her she is going to remove a piece of clothing. She asks him "Question number one A, B, C, or D," and begins to strip encouraging him when he gets the right answer. When naked she gives him a big reward by putting his big cock into her mouth and sucking him until he cums. She swallows and says "That's my good boy."
