Julie watching Jeff act strangely tailed him to the computer seeing her naked form on Jeff's computer she bum rushed him. Jeff felt his sister's thick hairy arm around his neck feeling her tuft of armpit hair at the back of it dragging him away from the enter button finally blacking out. Julie analyzed her profile the jock girl becoming cross at the program until she saw interests clicking on the box labeled computer she raised it from a 4 to a 100. Suddenly her head hurt as years of programming popped into her head. Power mad she selected her intelligence upping it from 41 to 100 her mind surged as thick spectacles appeared on her broad nose pimples dotted her face and braces in her mouth as reality altered filling her head with sci-fi looking herself over In Jeff's mirror she chuckled letting out a snort promptly covering her mouth in embarrassment.
Snickering she selected Jeff starting small she selected hobbies removing computers for fashion, reducing his IQ to 20, age 13, relationship to adopted, ethnicity to African, then his outfit sliding it to fully female, his short to long and blonde, scaling his testosterone from 72 to 15, and scaling mentality to 30% female hitting enter. The muscular brute stared at her brother's clothes became open toes sandals, a thong, skinny jeans, and a babydoll tee, looking like a cross dresser Jeff lost his body hair while his skin darkened to a rich ebony as he shrank his shoulders becoming rounded, lashes thickening, eyebrows becoming shaped and soft, his muscles shrank becoming lanky, AA cups budded from his smooth chest, his petite ass heaved out slightly, his broader nose shrank, his face becoming smooth and more oval shaped with pouty full lips, the now 13 year old boy's hair lightened to a honey blonde with blue highlights growing down his back as red polish appeared on his nails. Unable to help herself she selected potty training under skills unselecting it and hitting enter. Suddenly the passed out trans tween's clothes disintegrating skinny jeans vanished then his panties briefly exposing a micro penis smaller than Julie's clit and pea sized balls before a big puffy pink diaper formed around his waist. Julie bit her lip to silence her husky chuckles with a dorky snort.
Juliy knowing better than to let Jeff even try to use the program again selected the computer altering ownership of the program suddenly reality warped into her room a computer desk now beside her weight bench. Selecting herself grinning she got into the fine tuning selecting age 18 then muscle density and cranking it up to 100 then selecting muscle weight and adding 120 pounds she hit enter. Her manly body stretched hitting the six foot mark, next her muscles condensing becoming veiny, saturated, defined and fibrous, she got up flexing in her vanity as the nerdy girl's muscles surged bigger going bigger from wrestler to male bodybuilder to something out of a muscle fetishist's nightmare despite her new height as her eightpack formed ridges of indestructible definition, her sweaty hard pecs becoming the size of barn doors, her furry back and traps almost growing to the top of her head, her 45" arms becoming bulky 62" pythons. Standing on her hairy tip toes she stared as her gigantic fuzzy seperated quads and hairy pumpkin sizes calves bulged out "not bad!" The dorky muscle girl boomed in her new deeper mature voice.
