This video will tell you about the way you can train your dog to hump your doggy-fuck boobs! Humping your boobs is very popular with doggies, so you have to be able to train them too. To do this you need to first have a large pool of willing participants. You can either use one female subject or have several females compete in a race, and you choose the winner. The winner gets to hump her dog's boobs and the losers have to doggy-fuck with someone else.
