"Well, I could do a test on you, then you could do a test on me," Alan says. "That way we can see if it works on both girls and boys."
"And we can do anything we want to the other person?"
"Sure, and lets stay that way for the rest of the day if t works," Alan said.
"Okay sounds good to me. Who goes first?" She asked.
"How about you go first Katherine? Ladies first after all."
"OKay Alan, I hope you are ready, and no peaking." She sat at the computer. At the computer, she selects Alan. Then, she selects female. After that, she selects; 5'0", 100 pounds, c-cup boobs, shoulder length brown hair. Next she clicked save and change.
First, Alan shrank and got skinnier. Next his body became very feminine, with curves. Alan's chest started to grow so he had c-cup boobs. The change completed with his hair growing down to his shoulders.
"You made me a girl?" Alan asked.
"Yes, I did Alan. Or, should I call you Allie for the rest of the day?"
Alan blushed. "I guess Allie will work. Why did you make me a girl though?"
"Because, you are always teasing me about being a girl. Now, you get to be one for the rest of the day, and experience girl things."
"Okay, it's my turn." Allie walked over to the computer in her large boy clothes, and switched places with Katherine. Katherine stood off to the side, so she couldn't see the screen.
Allie sat there thinking for a while of what to do to Katherine. She didn't want to turn her into a boy, out of fear neither of them would be able to control their hormones. Then came to her.
For Katherine, she chose the age selection. From there, she chose three years old. A window popped up that said, "Diapers... pull-ups... or potty trained." Allie decided to click diapers. Then, she clicked save and change.
Katherine jumped away from the counter she was standing against. First, she started wetting herself, then started messing herself. This caused her to blush.
This stopped for a moment as her pants and underwear fell down with a thud. In them, she could see a small log of poop. She was now eye level with Allie's boobs, and another stream of pee rand down her thighs. This was followed by another thud of poop hitting the floor.
Next, Katherine was level with Allie's belly. Another stream of pee ran down her thighs. This was followed by another log of poop.
Katherine couldn't figure out what was happening to her. She was shrinking, peeing, and pooping. She realized that her shirt and bra were getting large, so she slipped them off. She didn't want to 'drown' in them. When she did this, she realized, she was getting younger and that is why she couldn't her boobs anymore.
Then the changes stopped, and here she was naked. She was also standing in a puddle of pee, and over a pile of poop.
"How old am I?" Asked a very naked and messy Katherine.
"Uh... I believe you are three. By the looks of it, you need diapers too."
"So, I'm a three year old diaper needing girl?!" Katherine asked.
"Yes, for the day, you are."
