Its a porn vn choices literally do not mean shit only what scenes you (there are 2 paths wich grant 2 diffrent scenes)
I've played dozens of AVNs. Choices absolutely mean shit in 70% of them. In a game where there is almost no indication on what your choice meant, I would preferably like have a walkthrough of sorts. The game is still relatively small so I'd understand not having one currently but as this game gets bigger, it might be a good idea for a system to be implemented to better track your standing with the girls or at least a written walkthrough.
Supp. So if u still play or found out by urself. What i did was, u dont get ur jack nutted when the teacher does it, u refuse all the way. So the daughter of the mother wont suspect anytving unusal. If she asks u if u have a thing, u say negative. Then if she asks with money, power and stuff. Dont answer that (i read it here but i went with money) the rest is simple
