Actually, Sleeze found and kidnapped Big Barda first and did a bunch of pornos with her. She was easily corruptible.
Then Sleeze thought it would be great if he had Superman under his control. Imagine a porno with motherfucking Superman? But when he managed to catch Superman and place him in the bed with Big Barda to start shooting the new porno, Superman actually managed to resist the corruption long enough for Mister Miracle to show up and save his wife.
So... Superman escaped, but Big Barda probably did lots of gang-bangs vids with black guys.
