Mandy Candy and Stefania Mafra have been held after in your class, so you can confront them about an essay they copied and turned in the same paper. Mandy and Stefania beg and plead their case to you to not fail them both and find the real cheater. You tell the girls their grades are as stands, an "F" for failing unless they want to do something for you. They can't tell any one bu if the girls worship each others bellies you will pass them on their paper. Stefania and Mandy agree to this deal and start one at a time belly worshiping, kissing, fingering and licking for your pleasure and to get an "A" on their papers.
