Did pterodactyl dinosaurs give birth to its young?

http://www.pornotube.com/channels.php?channelId=202&m=1672938 you need one puppet pterodactyl, three live pterodactyls and one girl who is willing to get dominated. the girl should be in reverse cowgirl position on one of the pterodactyls while intermittently performing fellatio on the other two. all the pterodactyls must be cawing and flapping throughout the process. after several minutes of this cawing and flapping, the puppet pterodactyl must enter from stage right periodically, open its mouth and look around.

NOTE: If you do not have a mechanical or marionette puppet pterodactyl, a simple sock puppet will suffice. It should also be noted that this position only works while actually in Jurassic Park, if you are unable to make the trip the pterodactyls can be substituted with guys with webbed fingers and toes.
