Your step mom has set up an appointment for you with the doctor. You explain to the doctor that your stepmom thinks that you have not fully developed into because your cock is so small. The doctor is surprised that you have a tiny black cock. The doctor wants you to give her a sample of your semen for testing. She asks you what helps you to cum. You tell her that women humiliating you about your small cock and womens feet in high heels gets you to cum. The doctor teases you with her body until you cum all over the place
