pterodactyl

A sexual act involving one woman and three guys. With all three men standing in a row the woman gets on her knees facing the men so that she can jack off the two guys on the outside while blowing the guy in the middle. With her head bobbing and arms jacking ferociously she resembles the mighty pterodactyl!

At first she was just skiing then Bill came over and joined so she had to pterodactyl.
