You run to stepMOMMY to tell her that there is something wrong with you cock, you are sooo lucky, because she is a doctor and she can check it by herself and help you. You are so embarrased and reluctant but she is determined to do her job and see your cock, in order for her to do her job she needs you to have a hard cock but cock can´t keep hard because you are nervous as your own stepMom is touching you, so she thinks that show you her boobs and her pussy might make you horny as soon as you see her naked your boner wakes up she needs to keep the erection for taking a sample of your semen so she is gonna do a blow job and a hand job to milk you. She massage your balls, use her saliva .... until you cum in her tits.
