More pics of lovely Gianna Michaels and her 38F natural tits. Gianna’s amazing curves were the subject of a video tape measurement from Jerked.com. Her large natural breasts (43.5 inches) and round hips/butt (46.5 inches) have helped generate a significant fan following. In the behind-the-scenes footage of her 2007 movie Blacksnake Bitches, she claimed that her breasts have grown even during her porn career. As of December 2015, Gianna’s filmography includes more than 500 credits (compilations included).
