Genital Jousting - online or with friends

"Genital Jousting is an online and local multiplayer party game about flaccid penises and wiggly anuses for up to eight players at once. Players control a detached penis complete with testicles and an anus. Multiple game modes provide a stimulating orgy of objectives: penetrate and be penetrated as fast as possible or compete in absurd, silly and sexually suggestive games and challenges."

I can't think of a better game to play with the inlaws at Christmas.
