Barnyard Billy 

Where a man is giving the hardest anal ever felt to either a male or female while a rope is tied around the taker's neck and to the end of the dick so that whenever the male pulls back then the head of the victim is yanked. They victim is taking it so hard that they also scream like a goat.

Tanya's neck was hurting fomr the hardcore barnyard billy.
