Jon turned back and looked at his four former tormentors as they slowly began to stir, and had to hold back a laugh as he saw their fate. Had he paid closer attention to his sister when she had commented on masculine and feminine energies, then he wouldn't have been surprised to their ultimate fate.
Where four studly men had once stood, there now sat four naked girls. They weren't overtly feminine by any stretch of the imagination, all possessing the same short hair cuts that they had before, but their lack of manhood between their legs gave indication to their new gender.
Jon thought for a moment, as the four of them were still out of it, and he slowly came to realize what had happened. His wish had caused him to absorb all of their masculine energies. This, apparently, only left the residual feminine energies that all people had to one amount or another. Absent any masculinity, he had effectively transformed them physically into girls.
"What the fuck!" finally came a shrill cry from the former Steve Farber, only for her to squeak back when she heard her higher pitched voice come out of her mouth. All four of them started to frantically move about, as they saw themselves transformed from powerful, impressively cut men to demure, almost frail looking women in a matter of seconds. Their fear only grew when they turned and saw Jon, the boy they had picked on for years, standing over them, far more muscular than he had ever been, and a predatory glint in his eyes.
"This will be fun," Jon said reaching down and grabbing the stone as it lay in his discarded jeans pocket. "I wish you four would stand up straight and not move till I say you can." In an instant, all four girls were at attention, sweat dripping down their brows as they watched Jon examine each one of them.
Jon felt like humiliating them, moreso he felt an indescribable urge to make each one of these newfound females pay for all the torment and suffering he had withstood over the years. He could leave them as they were now, and that might be enough. None of them stood more than 5'5'' now, and each would be humbly described as "plain" looking, with smallish breasts and a thin, almost rail-like body with little to no curvuture. They looked androgynous really, minus what lay between their legs. Or he could change them further, augmenting their newfound gender and turn them into his own personal harem, while leaving their mental states intact but imprisoned.
Finally...Jon decided what to do...
