Fear for Marcus rose like sour bile in her throat.

The very thought of it made him spit sour bile.

Her stomach pumped sour bile into the back of her throat.

The words were like sour bile in his throat.

He could feel bile, hot and sour, churning in his guts.

He tasted sour bile and wiped his mouth with the back of his hand.

A sour bile settled in his mouth and would not go away.

And he knew it, tasted it like a sour bile rising in his throat.

She shrugged, tasting the sour bile of fear but trying to keep any expression at all from showing.

He stirred sluggishly, then bit back sour bile and a need to groan.
