Please try to make sure you have the incest patch installed, and then try it.Shrink Appointment:
Can't you talk about Incest with him???? Is that totaly deleted.....
One of the few major modifications I had to do for the incest patch, was exactly so that when Myriam talks about her sexual fantasies with Dr Silver, she can also talk about incest, that required adding up one choice to the menu.
Also, when she goes online looking at porn, I had to modify so that there was also for her the choice to go look online for incest-themed porn .
