Someone should make a porn where a guy, a girl and a tranny all fsck one another at the same time. At no point in the video should there be someone not being fscked. While the man is fscking the tranny, the tranny should be fscking the girl. And the girl can get a strap-on and fsck the tranny while it fscks the dude. You can even throw Buck Angel or Diesel in the mix. In the end everyone should swap and swallow sperm, leaving the girl to squirt (piss) on the other two.
