The race was fast, but you managed to stay just behind the fastest of the four of you, Amanda. As she shoots over the finish line, you let out a sigh of relief as you follow soon after, followed by Liz, then Maddi.
You all watch with awe as the changes begin. Liz's AA cups suddenly swelled to C cups. As her boobs relax, you realize that her bra has just vanished. Then you look at Maddi as she begins to shift, ripple, then shrink. In her place now sat a light blue C cup sports bra. Then it vanished and Liz pulls up her shirt shamelessly, revealing her larger breasts, encased by the blue sports bra/Maddi.
In shock, you all remain silent as Liz drops her shirt back down. "Wow." you finally say. "It really works." you have always been the gullible type, but actually seeing it happen was completely different from thinking it would.
"Wha-what should we bet next?" Amanda said nervously.
