After some debate the two siblings decided to try on each others clothes first, for fun.
Sophie slipped on some of Alex’s boxers, pants and a t shirt.
Alex tried on a set of her panties, short skirt and camisole.
Once both siblings stepped out of the laughed at the ridiculousness of the others appearance.
“You, ha ha! Look even more like a tomboy than usual, ha ha!”
“Oh yea? He he! Well at least your outfit matches your sissy personality.he he!”
The two kept laughing, pilling on good natured insults till suddenly both stopped and stood up straight, arms pinned at their sides, a shiver going down both there spines.
Alex felt a deep crushing in his groin where as Sophia suddenly felt a pulling in hers. Both of their bone structures changed loud popping heard as their skeletons reformed. They closed their eyes in pain at the unstoppable transformation, unable to move. Sophia’s hands and feet got bigger, more blunt, Alex’s did the opposite and became daintier and narrow pink polish appearing just as it disappeared from Sophia’s finger tips. Sophia’s face became less cute more harsh and manly an Adam’s apple becoming visible in her throught, where as Alex’s did the opposite. Sophia’s hair soon traveled up her scalp becoming darker brown, where as Alex’s lengthened down to her shoulders gaining blond highlights. What budding breasts Sophia had once now vanished completely, on Alex’s chest small bumps formed only noticeable to someone who had gone without them till now. Both groaned as they felt their waists widen and narrow respectively, followed by a final tug or suck as their genders where now permanently inverted. It was officially over.
Both opened their eyes terrified at what their bodies had changed into. Instead they where met with the shock of seeing their own faces staring back at them.
They both screamed...
