Story: I was covering for my colleague when his sexy patient Lucy came in to see me. The pretty blonde said her issue was of an intimate nature but refused to tell me what it was. I tried guessing, but I figured it would be best to perform an examination when that didn't work. After a basic exam, it seemed like nothing at all was wrong with Lucy. At 21 years old, she was in perfect shape and health! Finally, she confessed. Her boyfriend had been unable to make her orgasm, and my colleague had helped make it happen for her! Well, what can I say? Like my colleague, I took an oath to help people in need. When I was licking her pussy, it was a special kind of tongue therapy, you see? And when I shoved my throbbing cock inside, I was doing exploratory research. You believe me. I am a doctor, after all.
