I think I figured what was the problem, at both instances, Nicole was pregnant. Thanks.
PS, momrelationship<6, is this typo or it's supposed to be less than six?
Edit, after playing with console a bit, I saw this was most probably a bug. I set Nicole's relationship to 4, and after that scene did trigger. Why I think this is a bug. You cant get to this point without having solid relationship with Nicole, every time you increase her corruption, it's increasing relationship too, at leas not at Corruption non-NTR path.
