During the process of sexual intercourse when the woman is riding on top of the man. The man then reaches into a jar of peanut butter and smears it into the ass crack of the woman, then calls the dog to lick out the peanut butter.
After that trailer park threeway my girl stocked up on peanut butter and always takes the dog on long walks in the woods.
