Brittany was the first person who came to Sandy's mind, the hottest girl of her class and possibly one of the sexiest in all the school, with an enviable F-cup breasts, perfectly round ass, a pretty face and almost 6 feet tall, she was the envy of all the girls, even Sandy.
In the school, after a hard physical education section all the students headed to the bathroom's showers, Sandy took her opportunity to talk to Brittany and delay her, leaving the two naked girls alone in the bathroom. When Brittany turned back Sandy took advantage and but the zipper in her back, for her surprise it actually worked and attached to Brittany's body.
"Huh? I feel something strange in my back" Brittany scratched her back.
"It's just a fly, don't worry" Sandy approached her.
At that moment, Sandy pulled down the zipper and saw how it created a big hole in Brittany's back.
"What's happening? I feel strange... And empty" Brittany whispered.
Then Sandy introduced one feet inside Brittany, she couldn't believe that it worked and excitingly introduced her second feet thinking that she will become the hottest girl in the class.
"Hey, what the fuck is happening? I can't even move my body! Sandy, what the hell are you doing!" Brittany screamed.
Sandy put her whole body inside Brittany, then she zip up the suit and Brittany stopped talking. She went to a mirror to check herself and saw her completely naked new body. Sandy was now in Brittany's body, she could feel everything like it was her original body as she grabbed her breasts, "I can't believe it, it worked! I'm Brittany now!" She exclaimed as her voice was the same as Brittany, she could see all her thoughts, her friends, family and boyfriend, she tried to think what to do next but she felt horny with her new body that decided to test it.
Sandy, now Brittany, introduced her fingers inside her pussy as she grabbed her tits, then started to finger herself even faster that made her cum, it was the best cumshot she ever felt in her life but even if she wanted to do it again she couldn't as she hear the school bell ring, so she took a bath and weared Brittany's clothes, leaving the bathroom with a little smile thinking what's the next thing she will do.
