When having sex, the female's explosion of anal gas set off a vibration and the male gets off from the vibrations.
Dick and Jane were having sex. Jane recovering from a mexican meal was being pounded so hard by Dick could hold back the gases, causing an explosion for Dick as well. Dick screamed "I love you baby and the Pinkerton" after he experienced the first of many pikertons. After that day she was required to eat mexican food before sex.
