Nasty lab technician Sabrina Deep helps you work out a sample

Sabrina is your lab tech today. You are supposed to give her a sample of your sperm and she has to sit and wait till you are finished. Since you missed your previous appointment, you have a limited amount of time to give her what she came for. The magazine she handed to you is not to your liking, so she decides that she will do what she can to help you work out a nice sample. Lab tech Sabrina takes out her titties and moves her hand up and down to mimic the jerk off motion that you know so well. Her nipples are hard and she seems to be a little more relaxed and willing to help you through your sample procurement session. Sabrina slides off her panties and she then offers to take your dick into her hand to help you some more. She looks up at you and she really seems to love her job. Her hand moves quickly up and down your hard shaft and you know that you will be able to give her a big sample.
