What is Shitstained Balls?
1.
An act of anal sex where the female (or male) has not used an enema before intercourse and purposely tries to defecate at the same moment of penetration, thus resulting in fecal lubrication of the rectal cavity. Continued sexual intercourse causes the excrement to eventually engulf the entire penis and testicals of the man. A position usually done in "scat" movies.
Jim paid Jane $400 extra to give him "shitstained balls."
