Jason saw a fitness center and decided that would be his next target. The fitness gym had many equipment in it from weights, treadmills, and yoga stuff. From what Jason could see was that the gym catered to both genders. Jason decided even though he was going to change the gym as a whole he wanted to follow someone within the gym to really see the changes. Jason looking through the class picked out a 27 year old guy.
Jason used the app to get the guys name and found it to be Gabriel. With that sorted Jason target the gym with the app and it produced the sentence "The Rough fitness center caters to men and women who use it to exercise." Jason was upset at this sentence since he knew it would create an error since he wanted to turn everyone in it into women. Jason thought and thought not wanting to try and try until he gets a sentence to work with. Jason figured that maybe changing the name will cause the change he wanted, so he changed "Rough" to "Succubus."
It didn't work other then making the gym look more like a sex parlor then a gym. Jason then went on to keep using the app on the gym till it gave him a sentence he could work with. Finally it generated one that he thought he could work with. "The Succubus fitness center is going to hold a class for basic martial arts for all within the gym in a few hours." Was the sentence it created. Jason immediately changed "martial" to "succubus". The sentence regenerated into "The Succubus fitness center is going to hold a class for basic succubus arts for all succubi within the gym in a few hours."
Jason looked into the gym and saw Gabriel become a woman with a nice hourglass figure. Jason realized that despite looking human Gabriel, now Gabriella wasn't one, instead being a succubus currently disguising herself as one. Jason then continued to change the gym. He played around a bit till he made it so anyone who uses the equipment will get muscular faster, but also sexier, whether that means getting a bigger bust, growing tall, getting curvier, or other things within a few minutes of using the equipment.
Jason watched Gabriella get on the treadmill. Within a few minutes he watched he change getting a hard on. Jason saw her grow from 5'9" to 6', her thighs thicken getting a bit of muscle to them. Jason was entranced by the changes as Gabriella continued to change almost putting on a show of her changes to him. Her ass expanded, he saw her pussy grow giving her a very visible cameltoe in her spats. He saw her tits grow, Jason used the app to see that they went from D to G-cups. Her shoulder length hair grew till it reached just above her ass and her hips widen till her legs were pulled far enough apart to give her a sexy thigh gap.
He continued to watch as she grew a sexy six pack on her belly. The last changes that happen were her growing some muscle and gaining a bit more fat till she was the perfect mix of sexy and athletic. Jason manage to kinda break out of trance to realize Gabriella became his dream woman. Jason wanted to go in to talk to her when he finally noticed the other succubi also changing while having someone watching them. Jason lost sight of Gabriella in the brief moment.
