Vicky easily wrestled the gun away from her brother. Checking the settings she made sure that it was set for reverse and then zapped herself. The beam seemed weaker somehow but she dropped to her knees as the changes began. Her deep moan of pleasure and pain rapidly gave way to feminine panting as her adam's apple melted away. Her lips plumped and filled out as she moaned again, reveling in the sensation of her increasing femininity. Long luxurious blonde hair spilled out of her head as her nipples became flush and erect. She rubbed her chest as her breasts began to return, jiggling as they grew from mosquito bites to their original size. The changes began to slow though. Her butt grew out slightly and her legs became graceful and feminine but her hips hardly widened at all. Her penis remained unchanged, throbbing wildly from the horniness brought on by the ray. Vicky tried to help it along by pushing on it but only managed to hurt herself. The ray had run out of power, leaving her a boy where it counted. Sobbing she threw the useless gun on the ground, her transformed friends regaining their senses in time to see the end of her botched transformation.
