Jeff read the description of the reality alteration and figured it should fix Jenny's ripped pants and unfitting clothes. Though, he made doubly sure that both he and Jenny would remain aware. Then, he applied the reality change.
Jenny had been squirming in her too tight clothes, while also covering her ripped pants with a blanket. Now, suddenly the discomfort disappeared. No more fabric digging into her skin. Her clothes felt fine. She was relieved. Her bra which she'd outgrown was especially uncomfortable, but now it fit her enlarged bust.
She then peeked under the blanket to see that her pants were no longer ripped. Her panties were no longer exposed. She threw the blanket away.
"You fixed it," Jenny said. She stretched and moved a bit. "My clothes seem to fit me perfectly."
"Nice," Jeff smiled. Now that she was no longer covering herself up, he glanced at his curvier girlfriend. Even if her jeans now fit, it was a tight fit, letting him admire her larger rear.
"So, I changed reality," Jeff said. "Like, to fix your clothes."
"What does that mean?" Jenny asked.
"Well." Jeff was about to explain, bit he realized he could just show her the Chronivac's explanation, and so he did.
Jenny read it, and then she asked, So everyone would remember me like this? Except us?
"I'd think so," Jeff replied.
"Hmm." Jenny pulled her phone up and used it. "Look here!" She showed a picture from a few days ago. It was of her, and notably she had a big chest in that picture, showing some cleveage she didn't usually possess. It was the her from after the change.
"All the pictures of me are different," Jenny commented as she scrolled through them.
Then she found a video from her cheerleading practice. She looked at it, and also showed Jeff it. Jeff noticed how Jenny's moves had a lot more jiggle to them in the video, how her chest bounced with her jumps.
"Did you notice it?" Jenny asked.
"Notice what?" Jeff replied.
"My position. It's different."
"Huh?" Jeff looked again, and realized what she meant. Jenny was the shortest and lightest girl on the squad, and as such, she was usually the one lifted up in the air and such, but that wasn't the case in the video. Some other girl, Nicole was her name maybe, climbed on top of the pyramid, with this new curvier Jenny's feet planted firmly on the ground.
Jeff and Jenny continued browsing the photos revealing her new past. Though, it wasn't too different. Beyond the obvious physical change, it seemed mostly limited to a slightly different wardrobe.
"Hmm," Jenny mused. If we change me again with the reality change function, what would happen then?"
"Well, it would depend on how we changed you."
"Yeah. Should we do it? I'm curious."
"Uh sure," Jeff agreed. Though, he wouldn't have minded if Jenny had stayed as she's currently for a while. Looking at photos was fun, but the real thing right in front of him drew his attention more.
Jenny moved and placed her juicy rear on the computer chair, and then asked, "What should I try?"
