When having anal sex with two girls at the same time with your unwashed, smelly member. At the moment of orgasm, you pull out and have the second girl swallow your filthy load.
If you ever perform the Dirty Sturgeon with a couple a good looking girls, be careful of kissing the recipient afterword. There may be a huge amount of santorum on her lips afterward. This is fine if you are into that sort of thing.
