Maddi shoots over the finish line just before Liz. You follow closely, with Amanda trailing behind.
Liz suddenly stands straight from her bent over, out of breath posture and turns to Maddi as she becomes a very horny sex slave. "What does my mistress wish of me?" she asks in a sexy, mocking-obediant tone as she ran her hand over Liz's front. Liz smiled as the changes begin in the other two, yourself and Amanda.
The world shoots up as you seem to get smaller. You reach up to grab your shorts as they begin to fall off. A rumbling in your lower stomach alerts you that something is happening, even as you feel your manhood shrink inside of your pelvis. You realize that you have not just gotten smaller, but you are now no older than 5 five years old. Sliding a hand into your pants confirms the existence of a pre-pubescent womanhood.
You gasp, your voice several octaves higher, even as Amanda vanishes and you feel your boxers shrink in to fit you underneath your baggy running clothes. You let go of your shorts and they fall to the ground, revealing a pair of pink girl's panties that cover your loins.
