Happy with the only change he had made to himself, he got to work seeing what he could do to Sharon. Even if their relationship was far from perfect, he loved her; and her uncanny ability to get his rocks off.
Her loadout made his newly sized member stiff with excitement; he had trouble not just knocking one out in the bathroom right then and there. But it would be infinitely better if he could properly place his excitement. He began by looking into her personality, making sure the appropriate reality and subject awareness toggles were active. She would not know the changes had been made, reality would change to support them, but he would remain aware of things as they were prior to the change.
He started by loosening up some of her controlling nature. Luckily, it was a slider. He reduced it by half. He also noticed that her fun levels were quite low--no surprise there. She was a "mature" adult and fun to her was found at the bottom of a wine bottle. He cranked it up a little closer to what he had observed his own as.
Digging deeper, he found a bank of "likes" and "dislikes' with descriptions next to each. He could clearly see many of the things he liked were on her dislikes; this relationship was definitely not going to last long if he didn't intervene now. Thinking back to his current predicament, he decided to swap a few things around. The first being "Large boobs" on the dislike category. The description read: "Dislikes large breasts out of jealousy. Originally wanted them until she grew old enough to realize that her B cups were the largest she would get, and hates the look of plastic surgery. Jealousy causes her to get angry quickly." This made perfect sense to John, so he removed it from the list and added it to the 'Likes'. The new description read: "Fantasizes about larger breasts, and fetishizes characters or women with large breasts." He also decided to add 'Anime' and 'videogames' to the likes, with the caveat that she had always been too shy to get into either, so she has been waiting to ask John about them and hiding her feelings behind anger. He also removed "men" from her list of likes, added under his own entry "is the only man whose cock Sharon craves." He also added a budding preference for Women, adding that she had just never given thought to exploring such a relationship.
He then went in and modified the description of their latest fight. The original contents were more or less as he had expected based on what he had found above, and noted she was worried about breaking up with him too. He decided to rewrite it based on her new perspective, so that she would come home soon to apologize with interest in more of his hobbies. She would feel guilty that she had been so upset with him lately, and would resolve to get closer to him.
Last but not least, he added a modifier to her perspective, so that she would be unable to interact with the Chronivac, even by accident. She would be completely disinterested in using it, remaining receptive to having it used -*on*- her. As he hit apply, one last prompt appeared on the screen. "Would you like to adjust subject's other body parameters based on new constructed reality data? This option will be presented as a new toggle on the subject's parameter list for ease of reverting the change or applying future changes."
John decided to hit yes, and watched as her figure on the display ever-so-slightly changed. Her proudly fit thighs loosened ever so slightly, and her waist became a little wider; as if she wasn't nearly as in-shape as she had been previously, and sat on her ass a lot more. But she was far from even "chubby." Her breasts followed suit, drooping just a little more than usual. Unfortunately they weren't any bigger as a result, but John guessed that was tied into her "likes" and the reason why she would now secretly fetishize tits. He could easily change it later.
He just had to wait for her to get home now. He decided to watch a lewd anime with particularly largely-endowed heroines on the main TV. There would be no avoiding her wrath if his changes hadn't applied, or if he had just imagined having a 6" dick before. But he now had faith that Sharon would be home soon.
