Two cowboys are sitting by their campfire, talking about their favorite sex positions. One says, "I think I enjoy bronco style the best."
"I don't think I've ever heard of that before," says the other cowboy. "What is it?"
"Well, it's where you have your girl get down on all fours, and you mount her from behind. Then you reach around, cup her breasts, and whisper in her ear, 'boy, these feel almost as nice as your sister's.' Then you try as best you can to hold on for 30 seconds."
