A Mond-ass-ian Cyberslut (Free-use)

[Sort of Spoilers regarding Bill's fate in the episode The World Enough and Time, which this is (very loosely) inspired by. If you have not seen the episode and wish not to be spoiled, turn back now]

The Doctor watched in shock as a distinctly female figure clad in nothing more than a silver thong and a face obscuring mask walked into the operating room. There was no mistaking what this was.

"A Mondasian Cyberslut!" He exclaimed. "Doc-toor." She said in her drawn out, robotic voice. "You know me? That's wonderful, it gets boring always using strangers." The Doctor pulled out his dick, walked behind the Cyberslut and started using her.

"Do you know where my friend Bill is? Surely you must, she'd love using you." The Doctor asked curiously.

"Accessing, Bill Potts. Locating, Bill Potts. I am.... Bill Potts." The Cyberslut said and the Doctor stopped. "Bill?" He said, voice shaking. They had turned his friend into a Cyberslut. They had turned his friend who would always complain about him and other men using her into the sluttiest being in the galaxy, one that fucked without question or complaint.
