Welcome to the clinic. We require a large sperm sample which has to be extracted from you. I know you have a fetish for rubber face masks, and how convininent that Nurse Subrina is right here...as I slip on her rubber face mask I let go of my inhibitions and responsibilities, and encourage you to do the same. I model my new rubber face on the examination table, stroking your juicy, rock hard cock. Would you paint my rubber face with all your cum?
