Just to be clear, the tightness setting does remain?: {1, 2, 3, 4, 5}
It doesn't progress from level to level after?: 1<2<3<4<5
There is no adjustment in real time in monkey on the sliders if you don't use them, meaning :
they will always look the same. So you will not see it be moved on auto because you kept doing her deep for a hour.
You move em by hand ,, or they don't move.
Big influence on it all is under Sluttify / Pleasure / Decay . drag that one to the right and suddenly you will be ballsdeep in whatever you want in no time.
As for the sliders under sexual.
Vaginal: Drag her Desire slider to the right(max desire), the other 3 left. That slider setting goes for anal as well.
Oral is different,,, top to botom of those is Right, Left, Right, Right, Left, Left.
Or just hit y button and see the best slider settings. That will also however change her personality into a superslut.
Somehow Y/Superslut makes the Decay setting almost all the way left. Drag it right again to get the full up and down motion and the other 2 more left or
all that will happen is her popping off and no real movement.
But at least with Y you can see the settings to get the gist. Exit the game and reload without saving and no harm is done.
Well that took some back and forth switching to the game

. Hope it helps.
