She wondered if the program could show her what she would look like as a boy. She flipped the gender of the image to male and the figure fuzzed for a moment before she was looking at a very naked, very male version of herself. Right down to a penis sticking out from the crotch. The face was similar if a little less rounded, but is didn't look much like her brother had or her father. That made sense though, she took more after her mother's side.
The hair was still blond, but where bother her brother and father were tall and leaner, the image before her was shorter and stockier. Not that she was particularly stocky, but this figure did sort of resemble her maternal uncle a little more than her father. Except the blond hair which her father had.
She decided to fiddle with the figure a bit more. The figure didn't have much of a build to speak of, which made sense. Amanda wasn't into sports or anything, another sticking point in her relationship with her dad. She was much more into books and art. Luke had been the athletic one.
She fiddled a bit with the muscle sliders, adding a bit of bulk to the figure on the screen, she also had to move the body fat slider a little to get the muscle to show up more. So, this is what she'd look like as a jock of a boy. She wrinkled her nose as she even noticed the figure was sporting more hair. Well, guess that was expected. She knew she had to shave a little more than other girls her age, her dad was a fuzzball and it looked like some of those genes had slipped in. Of course she'd get those. Luke had been pretty hair-free, which was more akin to their mother's side. Looking at this figure, it was no wonder not many believed they were related.
She tapped her lips wondering how he would look a little older. So she shifted the age to twenty. The figure gained a couple inches in height and bulked out a bit more. Hair that had been just a light stripe on the stomach and a little patch in the middle of the chest now covered a good deal of the chest and stomach, though the blond color made it harder to notice. He even had a short trimmed blond beard. She had to admit he wasn't bad looking, she feared she made a better looking boy than a girl.
She thought she heard a noise from downstairs. Was her dad home already? He wouldn't like her messing around in Luke's room. He was still touchy about it. She quickly went to shut down the program, but she didn't want to lose her work either, so she clicked the accept button thinking it would save and then just clicked through when it asked about altering reality. She still didn't know what that meant. She stood up to leave the room and suddenly every muscle in her body cramped up.
Her pajama top simply vanished, leaving her top completely exposed. But that didn't seem to matter much as her breasts began shrinking away. That was the only part of her that was shrinking though as the rest of her body was growing larger. Her shoulders spread wider, her torso thickening noticeably, hands and feet growing larger. Her breasts seemed to melt into two firm mounds of muscle on her chest, her nipples becoming only a quarter of their former size. Her arms more than doubled in size though, veins popping to the surface as the muscles under them swelled with new strength.
She found herself having to shift her stance as her hips rearranged and muscle bulked up her legs. A strange sensation in her lower abdomen had her bending over, hand on her stomach as it firmed up, but it felt like something was dropping out of her. She gabbed the waist band of her pajama pants which were quickly losing their legs as they shortened into boxers. Pulling out, her eyes practically popped out of her head. Sticking out from a patch of trimmed blond pubes was a cock. It was growing in size as she stared, a wince coming from her as she felt the two balls drop into her now waiting scrotum. It looked just like the one on the figure except, well, flesh.
Blond hair spread across her chest and abdomen, short but thick, somehow she new it was trimmed down, her pits itching as more grew in under her arms. The itching spread up to her face, and as her hand flew to her chin she was met with short trimmed facial hair. She moved he hand up to her head, her long hair now replaced with a shorter boy's style. The changes stopped as suddenly as they began, leaving Amanda gasping for air.
"Andrew?" Came a voice from the doorway. Amanda looked up to see her father standing there. Had he called her Andrew.
"Sorry, dad. I just needed.." Woah. Was that her voice? It sounded so strange and deep.
"It's alright. I come in here to think, too. I lost a son, but you lost your twin brother." He clapped Amanda on the shoulder, bringing her in for a bear hug.
Amanda returned the hug awkwardly, then looked down at herself. "I should, uh, go get dressed." She slipped by her father and went back to her room. Twin? Strangely memories were shifting into her head. They were twins, though they looked completely different. They were also best friends. Her memories of her relationship with her brother completely overwriting. She stumbled into her room, which had changed as well. While her books were still there, most of her art equipment was now exercise equipment. She stumbled over to the mirror and looked at her reflection which was the computer figure come to life. Disbelievingly she poked her furry, muscular chest. "Holy crap."
The longer she stood staring at herself in the mirror the less she felt like 16 year old Amanda, and the more she felt like he was 20 year old Andrew. He sighed and sat on the end of his bed. He had to go back into Luke's room and fix this when his dad wouldn't notice. But.. did he want to fix it?
