I do not understand. So get the red spheres to 8/10 balls filled for all of the four areas then get the bar filled to 90%? then end the day or fill one completely?
It's difficult to hit accurately. for the "3 tease events requirement", fill the pleasure bars of 3 areas until they are about 1 spheres width from complete, which is roughly 90% by my estimation, and stop moving the mouse or making the action.
I don't think it matters the order or which one you use as the Active or Last one but fill up 3, then work one until 90% and then stop moving the mouse (not the event, sorry I wasn't clear about that). They give a dialogue about being ready to cum and as soon as you stop, the bar of that area should fall to 50% full if you did it right. Then just build it back up to 90 2 more times and that should do it.
Edit: and someone mentioned and I hadn't noticed, but the 4th area should be Vaginal or Anal AND in penetration mode aparently. I hadn't experimented with this, so ymmv
