When a man is taking a girl from behind while that girl is eating out the asshole of another girl who is eating out the asshole of another girl and so on and so on for as long as the dog sled team is to be. It helps if the man has a whip.
I did a Sloppy Dog Sled with the Canadian national curling team last night!
