Meanwhile, back at the Facility... (Training Kaori #11) (Pixiv Fanbox)

While Alice was finishing up her adventures, Kaori was entering the home stretch of her vigorous sex slave training regimen. Week 6 commences with severe bondage and BDSM. At this stage, the slave is introduced to their Overseer, who oversees the remainder of their training. The Overseer has complete discretion as to whether or not a slave is worthy or not and has the legal power to terminate the slave at any point if it is not performing up to standards. The Overseer assigned to this slave is Gregor. Known for his quick temper, incredible strength, and insatiable sexual appetite, he is regarded as one of the center's top Overseers. He especially has a penchant for chokeplay with his slave. Gregor currently holds the facility record for longest sustained copulation with a slave before orgasm at 7 hours, 46 minutes. During this stage of the training, the slave is not allowed to orgasm. Its previous training should provide enough experience to withhold orgasm unless allowed by its Master.
