Then she held on to the arms of the chair like a child.
She came over and sat on the arm of the chair, put her arms around him.
Her free hand she kept on the arm of the chair.
Hit the arm of the chair with your hand when you're ready to give me what I want.
She sat on the right arm of the chair, her back to me.
She came and sat upon the arm of his chair.
He came and sat on the arm of her chair.
She came and sat on the arm of my chair.
And more, when she sat on the arm of his chair.
She stood with her back to us, one hand on the chair arm.
