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!”.
