Curiosity got the better of him, so he waited until Bryan had cum again, then changed his own setting to "female" and Jay back to "male". He cranked up everybody's libido (including his own) and set a half-hour time limit.
Simon hadn't even made it back to the bed when they two studs grabbed her and began molesting her body. Simon decided that she enjoyed being the center of attention like this, and groaned in delight as she was double-penetrated. The two boys fucked her hard and fast and deep, their hands and mouths molesting and biting and exciting her skin, giving her pleasure unlike anything she ever had before.
Her orgasm began soon after penetration, and kept up for most of the next hour. They dragged her into position after position, shooting their sperm into her once, then twice. The two boys fell off of her, exhausted by their heroic fucking. Simon was sore, aching, and feeling great.
In the morning, Simon awoke first and went to the Chronivac. The settings had automatically reset, but Simon decided he wanted more. Being a sex-crazed girl was BETTER than being a frustrated sex-crazed boy. Then he decided to keep her options open.
So he changed himself into a dickgirl permanently and set it on "unaware" - as far as anyone was concerned, Simon had ALWAYS been a horny girl with a penis. She knew Bryan and Jay wouldn't object to having a horny dickgirl around - Bryan collected dickgirl porn and they all watched it.
Then the 'overwrite' button was pressed. Simon the 13-year-old boy was gone forever, and only Simone the 13-year-old dickgirl remained.
