The Extra Credit Society 3: A Good Little Tutor - The Extra Credit Society

It's only been a few weeks since Chelsea Baylor and Helen Park had their lives changed forever. Their handsome physics professor - Doctor John Warner - thought he had caught them cheating, and offered to bring them in to his "Extra Credit Society, " which turned out to be a sex club run by him and his wife, Chantal. Other college students turned out to be involved as well, including Chelsea's boyfriend Cameron, who turned out to be just as sexually omnivorous as she had now learned she was. Chelsea and Helen find themselves getting deeper into the Society, after Chantal and Doctor Warner asked them to find new recruits.
Then Chantal comes to Chelsea with a mysterious offer, which she finds equal parts confusing and intriguing. What had seemed a fun sexual romp might not be so consequence free as they thought...
