69x2 = Fun makes no sense. First of all, it automatically has to have 2 people, otherwise it's not 69 but oral masturbation. So what's really happening here is two separate incidences of 69. Does this mean they do it twice, or there are four people? If it's the twice thing, wouldn't 69 by itself be fun too? If it's the four people thing, I can't imagine it being fun. The logistics of it would be crazy. Like a sexual Jenga. Who's licking who where? They build up this enormous structure, someone cums too early, they remove themselves to clean up and the entire physical skyscraper just falls over.
Lame.
