When you are mutually masturbating, while laying or standing back to back sharing a towel which is passed underneath both of your crotch. During
masturbation, both partners “saw” the towel back and forth as if they were looking to
dry their taints. One or more participants then begins to shit into the towel, with both partners continuing to “saw” the towel back and forth which spreads the shit all over both participants’
junk.
