Her hands tightened on his and did not let go.

Her hand tightened around his, as if she would hold him to this world.

Her hand tightened in his, and he let it go.

His hands tightened for a moment almost to the point of pain.

After a time he felt her hand tighten upon his arm.

But her other hand had tightened on the edge of the window.

Even his hands did not tighten on the arms of the chair.

Her hands tightened on the arms of the chair with the effort.

Her hand tightened, then fell away, and she said nothing more.

But his hands tightened on the arms of the chair.
