you could make the convosation system when you first interact with the girls this could let you ask the girls to train you then add prereqs for some of the talents while also having none for others
example talking to hanah and asking for training would make her feel pitty on you and train you
alt idea
asking for rough sex
and defeating the girl who trains for rough sex could give you two diffirent versions
the trained one could be more staged and less aggressive
while the domination version by defeating the girl who trains in it could get you a domination version where you truely know how to rough play the girls
the diffirence could be night and day learning it means you dont have confidance in it maybe doing things like pinning with less confidance but having the rough play dom could make incy push girls down and mate them with no fear
