The doctor examined the two boys, checking their height, weight, and anything else he could measure. "Very good. Now, boys, what I am going to show you is an experimental prototype. If you want to back out, do it now." The boys both shook their heads. "We're ready, doc!", said Rian. "Okay. Now, boys, I want you to try these on." He handed them what looked like a pair of pants. "Um, doctor? These might be a bit big on us.", said Bradley. "Oh, that's not a problem." Bradley and Rian donned the pants, which snapped to fit. "Whoa! Is that it?" "No. We are working with an experimental device that allows you to modify your body in any way. Let's try on you, Rian."
The doctor connected a device to a point on Rian's pants. "Let's see..." The doctor inputted some settings and the device read them aloud in a robotic voice. "GENDER: FEMALE. AGE: 22. LEG BUILD: ATHLETIC. POSTERIOR SIZE: LARGE." "Whoa, what?" Suddenly, a jolt went through the wire, giving Rian a bit of a shock. The pants were vibrating, or that's what it felt like. His legs began to tremble, as they grew in size. His hips grew larger, changing his center of gravity. His legs were pushing together, crushing his small penis, but that pain was quickly relieved, as it disappeared. His butt began to grow larger, until each cheek seemed to be the size of a melon. "Holy crap!" Rian looked down at his new lower half. His feet were still the same size, which were very small compared to his large legs. His legs felt powerful, and had increased his height to about 5'6", much taller than Bradley, and about the height of the doctor. "It works!", said the doctor. "Now, let me do something, then I want you to remove the pants." He pushed a button on the device. "INITIATING CLOTHING PROCESS." Rian felt a snap, and then he removed the pants. He was now wearing a pair of white panties. "Oh... oh my god." This feeling was completely new to him, and it would take a while to get used to it. "So, doc, what do I get to do?", asked Bradley.
