A variation on the classic Eiffel Tower. Two normal-sized men set up a Mexican Barbeque on a woman, and join hands. A midget with a kiddie-sized BASE jumping gear is hanging from the waist of the woman, and is fucking her vagina. When the midget cums, he releases his grip on the woman, falling to the ground like a base jumper.
