Reaching the last room in the hallway, Jen found her youngest (or at least formerly youngest) sister
Jessica. The 11 year old was sitting on her bed with her feet dangling off the side while she played with her
PSP and humming idly. Jen paused for a second, considering the current state of her family. With Holly now
regressed to a precocious 10 year old and Anna taking Holly's place as the oldest sister, that left something
of a gap in the middle where Anna had been. Jen was about to just bump Jessica up a few years and leave it at
that when it occurred to her that there was an even bigger set of shoes to be filled: hers. Or rather, her old
shoes as Ben. Ben had been the only boy among the four siblings, but now Ben was at least temporarily
(possibly indefinitely) set on remaining Jennifer, that left a slight imbalance to be corrected. Looking in at
Jessica, with her short cropped hair and tomboyish clothing, Jen decided that she could be made to fill the
void nicely.
Pressing "Select" brought up Jessica's profile on the screen. Working the buttons quickly, Jen edited the
"Sex" field, selecting "male" from the much longer-than-expected list of options. Deciding she might as well
kill two birds with one stone, Jen also added 3 years to the "Age" category before pressing "Apply". Jen
watched her sister intently, looking her up and down for signs of change. Jessica, for her part unaware of the
way her life was about to turn upside down, kept right on playing as the first of the changes manifested. At
first, Jen saw no sign of the coming gender reversal in her sisters transformation. She watched as her sister
began stretching, her feet slowly creeping toward the floor as her legs lengthened and her shirt riding up as
her spine stretched her torso out. Jessica's shirt began tightening as her ribcage expanded, and Jen saw two
small bumps begin protruding from her sisters chest.
She was just beginning to worry that maybe she had made a mistake when she began to notice the more subtle
points of her sisters changes. Jessica's shoulders were beginning to broaden, and those small bumps which Jen
had at first mistaken for forming breasts began to square into pecs. Bumps appeared on her sisters upper arms
as her biceps began tentatively pushing out against her skin. Meanwhile her hips had not followed her
shoulders example, giving her form a masculine taper. Jessica had not noticed all this happening, being too
focused on her game system, but as her hands began thickening and roughening and her voice began cracking
Jessica's complacency gave way to alarm.
As if spurred by her sudden panic, Jessica's changes accelerated dramatically. No longer tentative, her
muscles began to ripple and bulge, twisting her flesh and straining her clothes. Holding her arms out in front
of her, Jessica watched her limbs distort before her eyes, hair appearing and spreading up and down her legs
and arms. Small tears began appearing as the seams of her shirt and pants gave way. However, Jessica's
attention was focused downward as the critical part of her transformation started. To her horror, a small but
definite bulge appeared in her pants, quickly growing until it was painfully contained by her fly. Undoing the
zipper and buttons brought relief of the pain but only served to increase her distress as she watched the
growing organ tent out her underwear, and felt the space between her legs suddenly fill with a growing mass.
Lastly, her face rearranged, the jaw squaring and the first signs of facial hair appearing.
Jen let her sister endure a few more seconds of shock and confusion before pressing "Accept". She watched with interest as Jessica's shredded clothes knit themselves into something more appropriate for her masculine form. With that completed Jen turned and walked away from her brother's room...
