Just like you predicted, you have an abysmal run. The girls (well, the complete girls) pull ahead early. Even though you try changing how you swing your arms and sprint as fast as you can, your new bottom half is weaker and ungainly compared to your upper. It seems you will not have this problem for long.
Maddie made the bet and obviously wants to try it but gets outpaced by her friends. Liz and Amanda high-five at the end, Liz having finished just before.
Once you cross the line, your foot hits a root and you go down on your forearms and knees. As you turn to stand up, Amanda reaches out an arm for you to grab onto. Once you lift yourself up, you are too short... and getting shorter! The winners watch as Maddie and you shrink and change, sinking into your clothes and becoming silicone-skinned. Everything goes dark and strange ulling and tugging sensations occur until there on the ground are two piles of clothes with little lumps in them.
Liz and Amanda look around - nobody is watching. Liz grabs Maddie's pile and takes it to her bag by the start line. Amanda squats down and pokes through your pile, looking for the bodysuit part she is a little afraid of. Liz sees that Amanda didn't follow and picks up all the bags.
"Maddie's pile has the coin. I'll take her stuff home with me. Here's the stuff you need."
Amanda finally finds you and you feel her fingers slide inside the waistband and pick up. Unable to see, you can still feel your shape.
Looking at the skin-colored boyshorts with a fake but realistic appendage sticking out "Do you think that was his size in real life?" Amanda muses.
Liz laughs, grabs you and stuffs you in Amanda's bag The mixture of roughness or the nylon bag and zipper and silkyness of sports clothes make for a confusing sensation. Giving her friend a naughty look, she says "Maybe. You can see if he fits tonight."
Amanda takes her bag and yours, scoffing an smiling... but also blushing. "See you tomorrow for breakfast?"
"Sure, see ya!" The girls part ways. Liz reaches into a bag and pulls out the coin, still feeling devilish. "I bet if I can make it to the bus stop the penises will be eight inches and we will be able to feel through and cum through the suits like they were part of us when we are touching the inside." Amanda was going to have a big surprise, she thought as she sat down on the bench to wait.
