Dark-eyed, dark-haired Serbian beauty Coco de Mal came into my office today with a secret she said she was shamed to tell me: she'd been walking down the street a few days ago, and had an incredibly powerful orgasm that nearly crippled her in public! I told the lovely dancer not to worry, that I'm a doctor, and there is no shame in my office. I suspected that Coco needed to learn to control her orgasms to avoid a repeat incident, so I asked if she wouldn't mind trying to replicate the experience in my office. Coco was a little shy, but she disrobed and climbed onto the exam table to show me how she masturbated. I could tell she was having a very strong reaction to this right away, so I offered my cock as an assistant to her performance. Oh, such a perfect body! I fucked her tight pussy until she came several times, confirming the fact that she has an unusually powerful orgasmic response. After I blew my load in her mouth, I suggested she come back if it happens again, and we'll try and work toward a solution.
