The 9/11 is a sexual technique performed by 2 men and a woman. The men have to lie down with their penises relatively close to one another so they resemble two towers. Then the woman has to "slam" the towers by inserting them in the vagina and anus or mouth one after the other.

Get the 9/11mug. The day in 2001 that a major tourist attraction in New York City suddenly became a major terrorist attraction, which later became a major tourist attraction. Washington, DC, was also affected by this phenomenon, but to a lesser extent.
