The rules were simple. Sex-Train had been devised by a group of 100 individuals from all parts of the world, strung together by an e-mail CHAT called NO RULES. The object of the game is to have sex as often and creatively as your genitalia will allow for, on the subway. The game was invented in response to a statement made by one of the NO RULES members. One day, while the group searched for a game idea to market to its members, a poet laureate from Chicago's east side, mentioned how horny she always became on his city's subway. Because of that, she developed a game, in which she tried to outdo her previous day's number of orgasms she achieved while riding to work.
