the blumpkin vagina platypus is the classic sex extravaganza. while a girl is giving you a blumpkin you have your pet platypus look on or videotape. to spice up the moment have the platypus join in and stick his platypus penis in her ass. if done correctly the platypus will have a fatal orgasim. Also works with a mecgerkin.
