Lucas grinned as the storm raged outside the empty house. His older sister Natalia was coming home for spring break, and he had the perfect prank ready.

He snuck into her old room and started fiddling with the automatic wardrobe changer she’d bought two years ago, the fancy machine that scanned your body and dressed you in perfect outfits.

Lightning flashed. A massive bolt struck the house at the exact moment he was inside the machine. The device screamed: “Subject not recognized. Calibrating DNA…”

Circuits sparked and smoked. Metal clamps crushed his limbs in blinding agony. Lucas screamed until everything went black.

When he woke up, the pain was gone. But everything else was wrong.

He sat up slowly, long silky hair cascading over his shoulders. His hands, small, delicate, with painted nails, rose to cup two full, heavy breasts. A narrow waist flared into wide hips and a round, firm ass. Between his smooth thighs was a soft, hairless pussy.

“No fucking way…” The voice that came out was Natalia’s, exactly how she sounded two years ago when she last used the machine. Lucas staggered to the full-length mirror. Staring back was his 21-year-old sister’s perfect body, frozen in time.

He ran his new hands over every curve, squeezing the soft breasts, pinching the sensitive nipples until they hardened. A jolt of heat shot straight to his core. Curious and horny, he slid one hand lower, fingers brushing over the slick folds of his new pussy.

"Oh shit…” he moaned in her voice. The pleasure was intense and completely different, warm, throbbing, and addictive. He rubbed his clit in slow circles, then faster, sliding two fingers inside the tight, wet heat.

His legs shook as the first female orgasm ripped through him, juices coating his fingers. He kept going, exploring every new sensation, bringing himself to a second, even stronger climax while leaning against the mirror.

Panting, Lucas finally pulled his fingers out and stared at the dripping mess. The wardrobe machine was half-melted and smoking. His parents and the real Natalia would be back from the campus pickup any minute now.

“How the hell do I get my body back before they get here?” he whispered, still gently touching his new, hypersensitive pussy.
