The problem you're having is you're maxing out her frustration stat. You don't want to do that.I'm having major issues with Aunt Cami's "A little more corruption" event (Event 85 I think it was once called). I can get Mom's libido up just fine but I have progressed in her story enough that I no longer get any chance to only interrupt her and build up her frustration. Every time be it in the office or shower I only get the full relief event.
Further more even manually maxing out her frustration via console with a maxed libido doesn't trigger the kick out event on any day.
It really sounds like there needs to be some block to keep the player from playing too far and to finish corrupting Aunt Cami first before moving on with Mom, a better (simpler) trigger so when post frustration the kick out event is only looking at libido, or best overall making Aunt Cami sleeping in the living room a set event at least once a week
First help her out to get it back down to zero. Then once her libido is back up to ten with her frustration still at zero, visit her in the bathroom in the evening. Ryan will stop her from finishing without helping her. You can then go ahead and visit her room at night to see Cami leaving.
After Jacky's date reaches it's conclusion, Cami will always go out to the couch.
