Cosmic Changelling's Cosplay

The moment you select "Squirrel Girl" on the machine's glowing interface, the chamber hums to life. The door slides open, beckoning you inside with a soft hiss. As you step in, your breath catches when thick, mechanical arms descend from above, gripping your wrists and ankles with a surprising firmness. The restraints are snug, holding you in place as the machine calibrates. A robotic voice chimes overhead:

"Initiating Insta Cosplay transformation. Warning: Full-body restructuring in progress."

Before you can question that last part, the arms move with eerie precision, slathering a thick, warm goop across your skin. It feels strange—tingling, almost electric, as it seeps into your body. A shiver runs through you as the changes begin.

The first shift is in your chest. A pulling sensation tugs at your pectorals, skin stretching and swelling outward. You gasp as two soft mounds push forward, growing fuller and rounder with every second. The sensitivity spikes, and an involuntary moan escapes your lips as your new breasts settle into place, heavy yet perky. Your heartbeat pounds in your ears, the foreign weight feeling bizarre but… oddly exciting.

Next, the goop moves lower, smoothing out the sharp edges of your waist. Your torso pinches in, your ribs subtly adjusting as your frame takes on an hourglass shape. Then, a warmth pools in your hips, followed by a sudden widening. It’s as if invisible hands are sculpting you, pushing your hip bones outward to create that signature feminine curve. At the same time, your rear tingles—then expands. The once-flat shape of your backside rounds out, swelling into a soft, plump bubble that gives your whole stance a new sway.

Your breathing grows heavier as the final—and most drastic—change takes hold. A deep pressure builds between your legs, heat radiating from your groin. You tense as something inside shifts, a pulling and folding sensation replacing what was once there. A sharp gasp tears from your throat as your cock slips back into you body. 

The robotic arms retract momentarily before returning with fabric and accessories. Your new outfit is applied piece by piece: a snug, form-fitting bodysuit, soft gloves, and fluffy boots that cling to your now-lithe legs. You barely have time to react before the final addition—a huge, bushy squirrel tail—attaches seamlessly to the base of your spine. A jolt of sensation flares through you as you instinctively flick it, the weight adding to your new, bouncy demeanor.

The restraints release with a hiss, and you take your first step forward. Everything feels lighter, yet more alive—your muscles pulsing with an unnatural agility. Catching sight of your reflection, a grin spreads across your face. Your hands shoot up to press against your new, ample chest, fingers sinking into the soft flesh as a bubbly, almost uncontrollable giggle bubbles up inside you.

"Aaaawhooo!" you chirp, your voice now high, energetic, and adorably peppy. You hop in place, feeling the way your new body moves—every bounce, every sway, every flick of your tail. It feels perfect.
