Serena shouted, “GO!” at the top of her lungs, shocking Matt and Angela slightly but they quickly got running again.
Angela was the first to step on the next transformation pad, shortly followed by Matt. Angela suddenly shot up to about 6’2, and yelped in a much deeper voice that she usually had. As she continued to run in an awkward motion, her body completely reshaped itself, her boobs retracting in and become flat, solid pecs, and her frame becoming more masculine than feminine with wide shoulders and narrow hips. Her arms and legs become thick and muscular, completely shredding the clothes she had on before, leaving her completely naked. Angela blushed, but gasped loudly when she heard the loud squelching noise of her ovaries dropping out of her body to become testicles, and her clitoris thickening and lengthening to become a well-above average 9-inch penis covered by her vulva, now foreskin. Angela breathed a sigh of relief as her, or rather his, body was covered with tight running shorts and a tank top. Finally, his face shifted around to change from that of a teenage girl to that of an atttactive young man, stubble and all. He could now focus on the race again, sprinting much faster than before.
Meanwhile, Matt was completely oblivious to this as he experienced his own changes. He groaned in pain as his legs stretched out as if he was doing the splits, before bulging out at the end to become spinning tires. The rest of his legs contorted to change into the frame of a modern-looking motorcycle, along with his lower torso. Matt moaned loudly as his genitals changed into the motorbike’s engine, which revved loudly and started moving him along the track much faster. He was now simply his upper body attached to a motorbike at the seat, and placed his hands on the handlebars, running a jolt of pleasure through him as he sped along the track.
