Helping my step dad collect a sperm sample (with Casey Calvert)  |  (Random)

Casey heard you and her step-mom talking last night about going to the doctor. She is worried, but you tell her it is just for a regular physical. She wants to know more. She sees a container and you tell her that it is for a sperm sample. Oh, it is THAT kind of physical! Since you have been so good to Casey, she wants to help you with that sample. Would you like that? Get yourself comfortable and get that cock out. Start stroking it and she will take off her clothes for you. Those little tits look so soft. You only briefly wonder how your 18-year-old step daughter knows so much about stroking dicks, but that thought passes as her ass is now in front of you. Her soft voice coaches you through a jerk session like you have not had in a long time. She tells you to pretend that her hand is the one stroking your cock. (You were already thinking that!) Casey asks you to tell her when you think you will be ready to give her that sperm sample. Maybe she can take your dick in her hand for a little while to help you along? She does so and you fully expect that you will be giving her a huge sample. Casey says that she is glad that her step-mother did not help you with this because she has wanted to get her hand on your dick for a while now. She asks you to finish yourself off as she reached for the container. She holds it for you as you make every effort to fill it nice and full. Casey is impressed with your load and she thanks you for cumming for her.
