I'm sorry but nothing beat the couple having sex at the Metrodome during the college game last year, and of course they were caught. The bigger issue was that both parties were having affairs on their mates, who were also at the game and completely unsuspecting that their significant others had disappeared for I think close to an hour to get concessions.
I wouldn't walk barefoot across a public bathroom, nevertheless lay my naked ass across one, so any chick who'd go spread eagle across the floor of one isn't a chick I'd let anywhere near my cock, because you know that shit is filthy.
if you look at the video/pictures they seem to be doing it on an article of clothing, so technically you can't say that she was spread eagle across the floor.....but for the most part, you're right, i agree. she's probably scummy as hell.
