Dr. Jayne is utterly bored with this medical trial she is running. You are just another patient and she hardly even looks you in the eye. You take your pill as part of the study and she settles in to observe you for any side effects before sending you on your way. Before long you notice you are getting hard, really hard. You can't leave the office with a throbbing erection and since it's probably a side effect from the meds Dr Jayne has to help you so she can move on to her other patients. She doesn't enjoy it, but she strokes you. Soon you shoot a huge load all over her face, as soon as she tastes your cum she needs more. You are still rock hard so she sucks you until she drains you of even more cum. Your erection is still strong and now she is so enthralled with your cum that she wants it inside her. She wants to ride you and be filled with your cum- she wants you to get her fertile pussy pregnant. She needs it. She rides until you cum so much your jizz oozes from her pretty pussy. As you are recovering she gives you an injection as your vision fades you realize she has you now and will use you for your cum anytime she needs it.
