Gianna is minding her own business on a sunny day when she's accosted by the lackeys of two breast-masters. They've sent them out to find hot, big-chested girls who will agree to participate in a boob contest. This is not as easy as it may sound. They first gingerly ask Gianna if she has natural breasts. Once she has shaken them and they jiggle naturally, they ask Gianna to enter their tit-mobile. Inside the vehicle, one of the hooter-honchos is waiting. He examines Gianna's headlights with his hands, then gives her the face test. After these trials, they ask Gianna to compete in their boobie-banging contest. She has the afternoon free and seems curious so she agrees. The breast-master immediately drops his jeans, up pops his rod and down goes Gianna's head.
