III. Lips and suction
Communication of change in lip location (near horizontal directions) or suction (vertical finger pressure)
A distance between the OW's index finger and thumb of their left hand may suggest a distance between the RE's lips.
The ear-pulling exercise may not be practical to direct points of location ranges and reference if the RE's scalp cannot distinguish the feel of the OW's thumb from their left fingers, unless the mouth lips are closed and uniformly applying pressure to the scalp. However, the index and ring fingers next to the ear's clamp may adjust the distance between the two lips, as the two fingers may brush forward or away from eachother along the RE's head. Complication with tongue directions are addressed later.
Communication of point of reference or range of suction
The pressure of these fingers may direct an amount of suction. Points of reference or a range of suction may be communicated by strokes of the ring finger on the same directing hand. As pressure and location of the index finger (or middle finger, to be discussed later) and thumb remain constant, the ring finger stroking one way may increase mouth suction, and vice versa.
These two commands of location and pressure could instruct the lips to clamp a certain part of the skin. As pressure is applied with these digits, the OW's left hand palm may also apply some pressure, then they may lift their index finger and thumb from the scalp, directing clamping and pulling skin with the lips until palm pressure stops. The strength of skin pulling may be directed by the amount of palm pressure.
When the OW's middle finger and thumb are used, this may imply the RE's teeth are against the skin of the OW as lips still have some sucking role. To distinguish the feel between the middle and index fingers, a nut or seed shell may be ground or cut, drilled, and tied onto the fingertip.
