The woman next to me held both hands over her mouth.
She put the back of one hand over her mouth.
It was like I had no control over my mouth.
She pulled back and put her hand over his mouth.
She put her hand over his mouth when he started to speak.
That was when the hand came down over her mouth.
Then they just held me there with a hand over my mouth for a little while.
A hand came from behind, over my nose and mouth.
Next moment she was caught in a strong arm, a hand coming over her mouth.
The boy nodded as best he could with the hand over his mouth.
