You will probably all be into scat in 3 years. I've watched mainstream porn become more and more perverted each year, and scat is inevitable. Just look on the p2p networks. There are so many people sharing scat porn its rediculous. Its already huge in Japan, Germany, and Brazil among other countries.
You've got to understand how someone can be turned on by a hot girl shitting. Most girls will never even mention shit. Scat porn is just the next rung in the perversion ladder, right after pissing.
