The race starts off with Liz in the lead. Because of her smaller chest, she has a weight advantage and shoots ahead of the other girls and crosses the finish line first, with you Maddi close behind, then you, and finally, Amanda.
Amanda mumbles a little under her breath as her boobs get smaller and smaller, while Liz's fill out from their AA size to DD size. Her breasts now bulged against her shirt as she rubbed them, while Amanda rubbed her now flat chest underneath her bra.
"OK," Liz said. "How about next bet, fourth place turns into a bra to fit these monsters, while third turns into a shirt that's big enough to let them hang a little." She said, trying to release the strain on her monstrous breasts. You all agree and line up again to race.
