Rick swiped through the screens before making any changes just to see what he could do. There was the physical screen, the mental screen, the group transformation screen, the timer and revert page, the apply page, and the saved page. When he got to the saved page the app asked, Would you like to save the current profile? Rick tapped yes and stored his profile in number 1 which turned from transparent gray to solid gray. With that done he went back to the physical screen to make the necessary adjustments to change himself.
The first thing he really looked at was the sex slider. It was a little to the right of male and beside the slide the word "intersexed". He has to figure that it meant he had a little bit of female parts in him. He slid the slider all the way to the right and once it was there the word changed to "female". To go with his new sex he changed his name to Tracy. For age he slid the slider to 10 years just to see what it would be like to be a 10 year old girl. His height and weight had automatically adjusted during his first two changes and he was satisfied with them so he moved on to hair length. There was a model of him in the background following the changes he was making and as he slid the hair length slider he the hair on the model grow. He stopped when the hair had reached waist length and he stopped changing things on that screen since he was satisfied with everything.
On the mental screen he was kind of surprised to see that his sexual preference was bi but he left it as it was. Going down to memories he moved the slider to the middle so it was 50/50. He figured this would give him the memories of being a girl without risking losing his memories of being male. That was the last change he made on that screen. Once again he swiped to the saved page and saved the new profile to number 2. On the apply screen he saw two apply buttons, one on top and one on the bottom. He figured that the one on the bottom must be to apply it to the self so he tapped that.
A tingling went through him and he started to shrink. He went from 5 foot 8 inches to 4 foot 6 inches. At the same time his body was regressing, his body hair vanishing as he got younger. Once he had finished his regression his hair grew down to his waist as his dick shrank and his balls pulled inside his body. As his dick shrank the urethra detached and moved to below it. His dick continued to shrink until it was a little nub between his legs. A hole formed below his urethra drilling into his body forming his new female genitals. The physical changes were done now and new memories came flooding in almost drowning him. After a second or two the flood of memories stopped and his old and new memories balanced out.
"It worked," he said in awe as he looked himself over. His clothes didn't change with him so his shocks and shoes had fallen off his feet which were covered by his pants. He decided to take his clothes off and look at himself in the mirror in his room. He had memories of being naked as a girl but he wanted to see first hand and really look. He knew many would find this disturbing or consider him a sicko but he wasn't doing it for a perverted reason. He had always thought that he should have been born a girl and now he was. As he looked into the mirror he thought that he looked pretty cute. As far as he could see there was no sign of puberty yet so his body was hairless. Smiling he tapped apply again so he wouldn't change back after an hour. Now he had to wonder if the app could change his clothes to fit his new body. Before he could see though his doorknob started to turn. Someone was coming in and here he was a 10 year old girl naked in his room. He froze as the door started to open. Who was opening his door?
