[Tex/LaTex] Indent first paragraph only once

indentationparagraphs

I'm writing a document in English which includes an abstract in Spanish. In Spanish the first paragraph of a chapter should be indented, while in English shouldn't.

If I use indentfirst package, all first paragraphs in the document would be indented.

How can I indent a first paragraph only once, i.e., without affecting other first paragraphs in the document?

EDIT: I only want to indent the first line of paragraphs. \indent doesn't do the job, maybe because it's overridden to not indent first paragraphs.

\indent does not work as the code LaTeX inserts to remove the indentation after a section heading really does remove the indentation box, even if added explicitly.

Try

\section{hhh}
\hspace*{\parindent}aa bb ccaa
