"Please please fuck me now," she begged him, unable to stand the teasing any longer.
"Get over here and suck my cock," he said dangerously. "Or would you rather I flog you?" he asked, a glint of amusement in his eye.

"So," he whispered into my ear, "what shall I do with a horny little slut like you?"4. For a quotation within a quotation, use single quotes, though I don't think this is terribly common in erotica:
"Have you read 'Deep Throat Made Easy' yet?" he asked her offhandedly.5. If a quotation is more than one paragraph long, don't use end quotes at the close of the first paragraph. Use them only when a character is done speaking.
