Luna is an insanely hot, perfectly submissive, and very sick girl. So let's just that it was a good day at the office for Dr. Mercies. He turned Luna into the most elaborate anal puppet doll he's ever created; then he used her ass and mouth in many sadistic ways. She got a very rough anal pounding while dangling in the air, spun around for some ass to mouth, and got a hard training session with a harsh wire paddle and two canes. Then she gagged on his cock for a long time, until he mounted her onto her doll platform for additional future use.
