Ella arrived at her house quickly, since she lived near the school. When she got there, she found she found a package on the doorstep that was addressed to her. She thought it was strange because she hadn't bought anything and no one she knew should know this address yet. She took the package and went into her house.
No one else was at home, so Ella went straight to her room to store the package and then went to the bathroom, where she took off her dirty clothes and took a shower. After she left, she took the clothes to wash and then went back to her room.
Once she was clean, Ella opened the package she had received and can hardly believe it when she saw that she had received a transformation gun just like the one Christy had used to transform her.
"Is it really the same gun? I used hers a little and if this one is the same then there is no mystery how it works. I have to test it." Ella said. As there was no one else in the house, she programmed a change she wanted and shot herself, which had an immediate effect and made her grow to 8 feet tall. She had activated the reality change, so all of her clothes grew together and continued to fit her perfectly. "Cool, it worked." she said
While wondering how she could use her weapon, Ella heard the sound of the garage door opening and looked out the window, where she confirmed that it was her older brother, Brad, who had just arrived. It was there that she had an idea. Despite being brothers, she didn't get along with Brad and often thought it would be better if she had a sister, so she kept the transformation gun and went to meet Brad.
"Ella, are you alone at home? If so, you can prepare something for me to eat, I'm hungry." Brad said with an air of arrogance.
After that Ella decided to test something, then she took advantage of the distraction and shot him, and just watched while Brad's height decreased, his hair grew to his shoulders, then his body gained curves and breasts grew. In the end Brad was no more, as he had become Cindy, Ella's new older sister.
Ella, wanting to test whether the observation she had placed on the transformation had any effect, she came up behind Cindy and grabbed her breasts.
"Cindy, don't do this. You know what happens if you continue." Cindy said
"That's exactly what I want to see, I was waiting for you to get home just thinking about it." Ella said
"Okay, let's do it as you want, but not here. How about we go to your room?" Cindy said and the two went up to Ella's room. Once in the room, Cindy took off her clothes and said "I am ready to start."
Ella looked at Cindy's naked body, aware that she was the only one who knew that within minutes she was a guy and was now a very beautiful woman. Soon after she went to Cindy and started to suck one of her breasts, meanwhile she stimulated the other breast with one hand and with the other she put some fingers inside her pussy.
Cindy moaned as her pussy got wet, but soon after Ella felt her pussy tighten around her fingers. So Ella took her fingers out of her pussy just when she started to feel hairs growing on Cindy
At this moment Ella only watched, seeing that the observation she made had an effect. At this point Cindy's entire body was covered with gray hair and a tail grew behind her. It also had her teeth becoming sharper and her nose turning into a snout, ending with her vagina inverting into a dick and balls.
""It worked, I really have a sister who turns into a shemale werewolf whenever she gets turned on." Ella thought
"Come on Emma, you got me really excited, see how hard my dick is?" the werewolf said
Emma, no longer holding her hard cock in her pants, took off her clothes and went to Cindy, made her lie down on the bed. Then she climbed on top of her and, placing her stick in front of her sister's snout, she said "Suck my dick."
Cindy obeyed and started sucking her sister's dick, and Ella also started sucking the wolf dick that was in front of her. They stayed in this 69 until the two came almost at the same time and each swallowed each other cum.
After that Ella lay down on Cindy in the position she was in, she rested there for a while feeling her dick turning limp, meanwhile she can feel Cindy return to the human vomma while watching her wolf dick and her balls being pulled inward leaving a vagina in place.
At this time their parents arrived home and Ella started to think about whether she was going to transform her parents too or not.
