Unpain is a fleeting pleasure.
It does not last because it is directly related to your unfolding actions. You always have to work for it.
The amount of unpain you get while grooming changes continuously.
You must analyze these changes and reorient your grooming strokes in real-time in order to keep it coming.
Unpain is like feeling your body shouting its relief.
In some occasions, you encounter enormous waves of unpain that can rival any other bodily pleasure.
Unpain pushes monkeys and apes to groom.
