I actually found this chapter pretty hard to follow at first. We have maid just turned up and got kidnapped, but is assistant's junior, and then she ran away from mangaka, but then was also made to sit with / bathe / get into bed with her (didn't they all run away without a word as soon as they saw her masturbating? surely this one would too) and why is she introducing herself if both of them know her already? None of the flashbacks look particularly flashbacky compared to the present, and then there are flashbacks of her working with him as well to muddle things even further.
I know it's essentially hentai so no one cares, but it's just kind of messy storytelling.
