Something... strange happens.

Cautiously, you stepped into the changing chamber as Barbara gave you a playful wave before the door shut with a loud CLUNK! The familiar light sudden shined on as you waited for Barbara to input the right details to have you dressed up in her outfit.

You blushed at the mental image of you squeezed tight into the Batgirl costume, having to pose as your mentor for the night while she enjoyed a nice evening with her dad.

Yep. She was definitely going to owe you big time for doing this for her.

Shivering as you waited for Barbara to finish, you shifted back and fourth on your heels, slowly growing impatient. What could be taking her so long to put some commands into the computer?

"Ugh, come on!" Barbara huffed in irritation, hitting the enter key again. The same DING of denial, with the same stupid message!

SUBJECT DIMMENSIONS INACCURATE. PLEASE INPUT PROPER DATA.

"Stupid thing!" The redhead huffed, moving the mouse over the screen to back out again. She had tried trimming some of your measurements down, but the scan kept correcting it! She changed the size measurements of her suit, but that didn't work either!

She was about to just try again until a small box caught her attention.

"Options…" Barbara read aloud, "Let’s see what we've got…" clicking the box, the computer screen changed. Looking over some of them eagerly, Barbara's phone buzzed as she received a text.

'Where are you?' It read. Her dad no doubt. She was running out of time!

Picking up the pace, the redheaded young woman quickly sent back an excuse about running a little late, before she turned back to the screen and clicked the "Change to Fit" option, brushing past the details in a haste before she clicked the Accept option.

Sighing as the damn computer finally accepted the input, Barbara leaned back in relied as the faint hum of machinery filled the suit up chamber…

You jumped in surprise as the arms around the closet finally kicked on. But instead of just squeezing you into the Batgirl suit, a green light scanned over you from head to toe, before flashing red.

ERROR. SUBJECT INCOMPATIBLE.

A computerized voice rang out as you blinked. What was going on? A mechanical arm descended from the top of the tubular closet, attached was a small needle and vial of some sort of brown substance.

COMMENCING CHANGE.

Change? You would have stepped back from that unfamiliar needle, but there was nowhere to run in the small confined pod. It quickly stuck itself in your neck and injected whatever it held into you!

"Ow!"

You yelped, holding your neck in pain before you began to feel… weird. Your skin felt numb and soft. Your limbs felt heavier and slower to respond. You would have fallen back before another set of arms descended and restrained you. Your mouth felt like it didn't work properly. As the arms ran over your body, occasionally giving your flesh harsh squeezes and massaging you, you glanced down at the work they were doing on you, and your eyes widened in horror.

You were being… shaped and molded! As though you now had the consistency of clay! Trying to work up the strength to scream, or even writhe free from the arms’ grip, your body was too sluggish and slow to get away. All you could do was watch in an odd mix of fascination and terror as your legs were shifted and shaped, the muscular frame slowly becoming smoother and more feminine, the leftover flesh being worked up and redistributed to your… thighs and butt. As more machinery wrapped around your waist, pinching it in, you were left with a very feminine legs and waist. Your flaccid manhood slowly twitching as another set of arms grasped it and began to knead it into your crotch!

‘No! I-I need that!’ You thought fearfully as you shifted and squirmed to no avail. Your new body consistency made the work much easier as you were given a very clearly female anatomy.

But the changes still weren’t done!

Slowly, but surely, the arms continued to work their way up your torso, smoothing it out, giving you a distinct curves, and moving now unneeded mass into your chest! You whimpered helplessly as you watched your firm pecks become a set of breasts, your shoulders were shrunk and arms worked into smooth, slender, clearly female arms and hands.

Even if this miraculously stopped, you’d be completely unrecognizable until people looked at your face, but as the arms began to grab at that and your hair, you knew it wouldn’t matter much either as your bone structure and face was pressed, pulled, and changed. Your hair began to feel longer as some sort of dye was put into it, making it red like… Barbara’s…

You felt another needle stick into your neck and pump you with another substance, and you quickly began to regain feeling again! Twitching your new arms, they quickly felt your face, that now had no trace of squareness or any other familiar shapes. Stumbling at the new center of gravity you had, you continued to feel up your chest, rear, and… womanhood as the familiar green light ran down your new body, followed by a successful DING!

SUBJECT DIMENSIONS: SATISFACTORY. BEGIN SUIT-UP.

Looking up, you barely had time to prepare yourself as a pair of purple and yellow panties were slid up your legs and fit around your crotch, a matching sports bra was put around your new chest as you once again began to try and fight the changes.

“Stop! Wh-what have you done to me?!” You demanded, cringing at the familiar voice of your mentor escaping your lips. A leathery black spandex suit began to descend from above you as arms restrained you, holding them out as you were worked into the tight material of Barbara’s batgirl suit.

You blushed at the feeling of the tight material clinging to every inch of your new figure, the machine tugging it over your arms and legs, snapping a yellow belt over your waist as the yellow gloves and boots were fit over your hands. You yelped as the black cowl was fit over your new head.

With your new look completed, you were finally freed and the metal doors slowly opened.

“Woah!” Barbara said impressed as you stumbled out of the wardrobe, your hand nervously going over the black suit tightly covering you, “That worked even better than I thought! I mean, you REALLY look like me!”

“I… don’t just look like you…” You gasped nervously, tugging at the wedgie your now level crotch allowed. Barbara looked at you confused before you worked off the mask the stupid machine had put on you, “That thing turned me into you!” You finally said as Barbara looked at her own face in shock, “What did you tell that thing to do to me?!”

Realizing just what she had input, Barbara bit her lip nervously before her phone buzzed. No doubt another text from her dad.

“I’m SO sorry!” Your twin mentor said nervously, grabbing you by the shoulders, “I know this isn’t what we planned! But… I know we can fix this!” Fitting the cowl back over you, Barbara began to walk toward the elevator!

“Wh-where are you going?!” You demanded, “You can’t just… leave me like this!” You gestured to your new form in shock.

“I’m so sorry!” Barbara repeated, “I’m just running really late right now! Don’t worry! I swear when I’m done, we’ll fix this! Just try to relax and just stick to the plan!”

“This isn’t what I had-” You didn’t get to finish as Babs left the batcave, leaving you in a perfect copy of her body. "...in mind." Looking down at the yellow batgirl symbol adorning your chest, you groaned.

When you said you’d pose as Batgirl for Barbara, you hadn’t thought it would be as literal as this!
