A boning marathon is an incredibly erotic time when a couple has tremendous sex for extended periods of time. A boning marathon often lasts for upwards of two hours. It takes indredible endurance from both the man and the woman. A boning marathon is often started after alot of drinking. As we all know, drunks last longer....if not forever. You can usually identify the participants of a boning marathon by their walk. They usually walk a little funny after hours and hours of hoTT sex.
