Goddess Brianna - Beating the Exam Milf!

You have been failing your classes and you skipped school on exam day. Miss Smith was nice enough to stay late one day and let you retake the exam. She calls you up to her desk to pick up your exam. As you reach out to take the exam from her hand she notices that you have answers written on your hand. She quickly pulls the exam paper back. She isnt going to let you retake the exam until you scrub the answers off your hand. But, she isnt going to let you go to the bathroom and use soap and water. She wants you to drop your pants and jerk your cock until the ink is removed from your hand. If you cum before all the answers are removed, you will not be able to retake the exam and you will fail this semester.
