I cannot seem to complete Milestone 1 no matter what I do. I am convinced there is something I am supposed to do with Rachael, but I can never make any progress at all with her. She jerks me off and will take off her shirt while doing so, she lets me join her for yoga including poses we do together, and she has me spank Linda when Linda is caught masturbating (which one of the grey stars says to do this twice, but I've done it like 20 times now). But nothing has ever changed with Rachael since those events. What am I supposed to do to make progress?
