6911 

Sixtynine eleven is the described shape of a love making act between two men giving simultaneous felatio. Two men sixtynining, the eleven is from their penis'. A homosexual version of a sixty nine.

Billy: "What're those two naked guys doing over there? Wrestling around?"

Johnathon: "If they've got each others boners in their mouths, I think you'd call that a 6911!"

Porsche 69-11 

Reverse Amazon with 2 dudes, wherein the top has his dick in the bottoms butt, however the bottom has his dick in the tops butt; the dick in butt combination resembles the boxter style opposed piston block of the Porsche. Both guys are both car and garage at the same time. Bonus points for simultaneous climax.

Blake and Zale couldn't decide who was pitching and who was catching, so as a compromise they did a Porsche 69-11

The most horrifying and dangerous sex move known to humans. It involves a jet engine, two penises, the Illuminati and an exploding nuclear vagina. I will not go into details.

No one shall be saved from the 69/11.
