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!

A sexual act involving two men and a semi willing female. The first guy begins intercourse with the women from the doggy style position. This most be done with the women facing a window. Meanwhile the other man is hiding in the closet. At the right moment, the two men must perform a switcheroo. As the second man enters the womens' vagina, the other who was previously performing intercourse, must run outside and wave at the women as the other man nuts on her back.
