Blumper-Decker-Dactyl

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!
