Dogsled Racer

This guy was into racing dogsleds. Every Saturday morning he got his
wife up, harnessed the team, and he and his wife would go to the
races.
One morning, his wife told him that she wasn’t going. So he told her
that she had three options: 1 - go to the races, 2 - he would fuck her
up the ass, 3 - she could give him a blowjob. He told her to make up
her mind while he harnessed the team. On returning she said that she
still wouldn’t go, she wouldn’t let him stick her from behind, so she
started to give him a blowjob. After a few seconds she stopped
suddenly and cried “That tastes like DOGSHIT”. “Yah”, he said, “One of
the dogs didn’t want to go either!”.
