Best way to raise submissiveness?

[Fatherwow]

So I know a few events have a chance of 1 time raising sub stats for some girls, and some girls like your secretary you can raise her sub easy by smacking her ass every chance you get but this does not work with all girls.. some it just makes them mad. So is the only way to raise sub by buying the sub books and giving them to them? And how do you raise sub if they don't want the books? Is there a base love requirement before they accept books? And is there a base sub stats they can reach before they like having their butt smacked?

Some ladies have certain talk topics that can raise their sub level, like with Samantha if you talk to her about food you'll either get a comment about ♥♥♥ that raises her sub level 1 or a comment about wine which raises her love points by 1. Taking the girls on dates a the pub and playing pool and darts helps as well...

Some actions will lead the girl you want to submit to gain some sub points. Some will gain when you are putting your massive rod in their buttocks or when you are releasing yourself on their face. A well known method is indeed to get them to the pub and play pool/dart to gain 4 sub point guaranteed. You can also talk to her right after by choosing the proper dialogue that will raise their submissiveness. And for what I tried, girls only likes having her butt slaps when you they have 25 sub point minimum.
