Firing Squad

When you marry 17 men and consummate the marriage with all 17 of them. You stand near a wall and bend over, with your gaping anus exposed (its gaping because you've had a deep anal muscle massage), and the 17 men form a line. They proceed to run up to your anus and take a single thrust one-by-one until you have come to a successful completion.

"Oh golly gosh, my hole is sore!"
"Why is that, Dan?"
"I just got shot over 100 times by the firing squad!"
