The larger the breasts are, the more pressure it puts on a girl's shoulders. Boobs move in three dimensions including forward and back. This often keeps busty girls away from sports. Scientist Anthony has completely lost his mind studying the sport and science of boobs. He says he's invented a device that can control girls and their swinging jugs. He secures Chavon Taylor to assist him. As she bounces her titties on the trampoline, Anthony slows her down, then speeds her up. The next phase of his experiments involves...what else?...fucking. "What a fine specimen," he tells Chavon as he prepares her for a blow job and tit-fuck before he humps her. Science marches on!
