The character of Superman has generated some strange and mostly unsatisfying porn parodies over the years.
In 1999, pornstar Tony Duncan starred in The Adventures of Super 18″ and His Friends the “C” Men. “More powerful than a burst fire hydrant, able to plow pink bottoms in a single thrust, more manhood than any other man on the block.”
Duncan was frequently billed as Mr. 18, Big 18″ and the like. Fortunately for his co-stars, that’s typical porn biz hype; he’s big but nowhere near that big.
Two weird Superman XXX parodies appeared around 1975-76. Marc Stevens starred as Souperbone, a joyfully horny superhero bringing sexual liberation to a great American city.
Meanwhile, Jeannette St. Michel starred as Super Lady, a superheroine who proved “that women can be indestructible fucking machines too”. We never doubted it.
The invaluable Alpha Blue Archives preserved both films, and both are available at our AEBN-powered online theater.
