Busty Schoolgirl Marissa knows she doesn't deserve an "F" Grade and she knows exactly what to do to make you change it to a passing grade. First, she flexes her biceps to put fear in you, then she takes her top off to expose her massive cleavage to get you rock hard! Then she instills fear in you by LIFTING you up over and over again with one arm to prove her strength dominance. She now knows that you're so ready to explode that you cant even hold out as she counts you down from 10! I think you'll be giving her that passing grade now!
