What is Muck It Up?
1.
After a good doggie style romp, the jizz left on the tip of your cock gets rubbed into the chicks bunghole. A little poop gets mixed in during the rubbing and you muck it up.
After banging the bitch doggie style, I blew on her back. Then I mucked it up for a bit, before banging her sister.

Muckit is when you take your cock and push it around in your bitches asshole...you smoosh around her shit and your gizz.
After I was done banging my bitch, I mucked it up.
