Favorite non-sex scene:
Molest Evelyn or Primrose and if you keep going far enough it allows you to give them a ... gift ... and that unlocks P5. You need to have A5 in order to not wake them up.
Why? If you did that then you would miss a lot of the content
Wait for A6 to get released as anything less will get you caught by Samarra (also known as wait for Belle to get it created). It is the scene I am most looking forward to besides maybe Nell in the tower or a revisit with the fairy queen.
Their sleep molestation scene works differently from the others. You only have a limited number of actions you can take here, and some actions are more "expensive" than others. Once you run out of actions, you are caught. Agility only gives you more actions before you are caught. The trick is to not push too hard but stop before it's too late. I might introduce some kind of hint system for that scene to give you an indication of how much left you have to go before someone wakes up.
I don't know how high you are planning the stats to go up but after max agility it would be nice to have unlimited actions
You can see the max in the game itself. For most stats, including Agility, it's 6. Even at that level, you won't have unlimited actions with those two girls. Don't worry, that won't be the end of it.
that'd be more than just nice since for me it kinda breaks the immersion when you're forced to rollback or reload everytime you get caught (it's only funny for the first time)
