At the same time I felt a man's hands close on my arms from behind.

I went over and put my hands on her arms.

As she did so, I felt the hair on my arms stand up.

As she turned to leave, he put a hand on her arm.

The girl moved up quickly and put her hand on his arm.

No one could have done a better job on my arm.

I put my hand on his arm to ask him what was the matter.

She went to him and put her hands on his arm.

She put a hand on his arm to stop him.

She sat up and put her hand on his arm.
