When you take a shower and then screw (have sex with) your sibling like theres no tomorrow! However, for a West Virginia Saturda Night Party you must not take a shower and both siblings must recive anal (could be with fingers or private parts).
I was so frikin' horny last night and since im single and have no girlfriend I had a west virginia saturday night!
