Yes, it's scat pornWhen we started watching porn, back in our early teens and for some, even before that, when our older and much experienced 12 year old friends wanted to gross us out and show us what they never wanted to show us in biology classes, we never imagined that sex could get so dirty and so messed up.
Holy shit, now that's a big piece of crapWith scat porn, what is there to say.
The crapping is the way that these people are expressing themselves sexually and it works for them.
