 Get the Houdinimug.
Get the Houdinimug. Another form of houdini would be when a guy is fingering a girl while she's sitting on his lap. And then he takes his fingers out and in a sneaky way substitutes them for his dick and make it feel like he put his fingers back in. Once he gets his dick in, he put his hands in the air and yells "hey look! NO HANDS!"
Guy 1: hey man, i pulled a houdini on my girlfriend last night.
Guy 2: awesome!
Guy 1: yeah, she had no idea how my dick got in there that quick!
Guy 2: awesome!

Get the Houdinimug. When you are having sex doggy style with a girl so she can't see you, pull out for a second and have your friend rush in and start making love to her instead. She will never know until the sex is done, or they change positions and she sees it is a different person.
