There is HandLaTeX that could do it.
Edit:
Beware, this package does not include any font, it just randomize the appearance of the text. Used with an handwritten-like font, it gives a satisfactory result.
Example, using the Fountain Pen Frenzy font:
\usepackage[]{hand}
\begin{document}
\begin{handpar}
Lorem ipsum dolor sit amet, feugiat ad metus vestibulum at
eget. Condimentum est dictumst, quis cras congue et turpis, ornare
lacinia hendrerit platea in. Nulla est proin pellentesque hendrerit
nulla vitae.
\end{handpar}
\end{document}
Output:
