When I was at the Buffalo Chip campground, I saw some pretty nasty shit going on. One of the things I saw was an old motorcycle that had about a dozen dildos attached all over it. Women would clean off a dildo with rubbing alcohol, put a condom on it, an slide on. They would start up the bike and grind away on the dildos. There would be maybe six women on it at a time, some backing up to it, some throw a leg up on it, and they all try to cum at the same time. Unfortunately, I do not have any photos, as my camera battery died too early.
No, I didn't try it.
