A word a month – Zena Fulsom
From the dictionary of unusual sex:
Fulsom, Zena – North American porn star famous in the ‘80s for her really colossal bosom, which several years later was revealed to be just an easily removable rubber prosthesis created by a special effects studio. Her incredible success opened the way to a whole genre of “impossible” pornography based on similar tricks, which today includes also actors with phalluses 20 or more inches long, penetrations performed with the whole head, anal >fistings up to the shoulder and similar absurdities.
