alot of characteristics

"Sex change machine"
jon wished and all of a sudden their was this box with a couple of levers with labels like hair color and length, breast size (if female), penis size (if male) muscle mass, IQ a couple of small switches with each a different characteristic like giving instincts for the body rearranging the mind and memories, straight (for the sex you will be), same as normal, bi some of the switches had odd characteristics like female with penis, male with boobs, likes to crossdress, and their were several more. Their was a big red button that said "start"
they both said "you try it first"....
