The act of receiving a blumpkin while taking an upper decker as the female is also giving two guys on the sides handjobs (the head and hand movements mimic a pterodactyl flying.)
Dude, I felt like I was in the prehistoric era because of how believable her pterodactyl was when she was giving us a blumper-decker-dactyl!

Yes, it's true. A Pterodactyl once hooked up with a Grizzly Bear. They made love under the sea, in outer space, EVERYWHERE. Yes, that bear gave birth to a motherfuckin' Bear-O-Dactyl who just might Ptero-You a new asshole. So beware, motherfuckers, beware.

When a chick is performing the pterodactyl, the guys rotate positions so that each one can get some dactyl spit on their dick.
That little ho wanted to play ring around the dactyl, so we all saddled up and rotated on that bitch until bukkake time.
