Her mindset

For the first time in his life, Jim woke up to getting his dick sucked. Looking down over and past his chest he could see Lisa's dark and purple mane bopping up and down as she slurped enthusiastically on what had quickly become her favorite thing to do. Reality had been set to a path where she'd always been fond of sucking cock. Her much more vulgar nature however, was still very new to both herself and those around her.

As climax came ever closer Jim noticed how his girlfriend was still covered in last nights cum. As Lisa did her thing Jim slowly reached for his phone which at some point during the night had made it to the nightstand next to his face.
The first thing he noticed as he unlocked his phone was a notification from "the app". Another change had become available and had to be used before the end of the day. As he read this his mind started brainstorming ideas for changed he could make to Lisa. Just the idea of transforming her had become very alluring to him, and he had no idea why. Nor did he care. He just found the idea incredibly hot all of a sudden and payed it no mind what so ever as to why that was.
As she kept on sucking, Lisa could feel her boyfriend's cock stiffen even more in her mouth as she sucked, not aware of what he was currently in the process of doing.

Looking through the list of options, Jim saw a few interesting ones. Whichever he chose one thing was still for certain. Lisa's vulgar nature would become like second nature. Given how whenever he seemed to make a new change, she forgot all her previous ones. Lisa now believed she'd always liked to dress like a sexy goth and that her hair and lips were her own ideas. Her addiction to sucking cock was also now become part of her. And after this next submission? She'd remember herself as always being vulgar and crude. Perhaps another mental change would do? Maybe something that made her more.. compliant with this whole situation. Though it was quite hot how she protested yesterday about her vulgarity Jim still thought it'd be the wisest to bend her mind ever so slightly to make her more accepting of any changes.
Not too bothered with the details of how this would play out long-term, Jim got to work on one of the brackets.

"My partner's mindset is too resisting. If I could change her mindset, I'd make it more accommodating to her changes."

Jim didn't feel any rollercoaster or waterslide this time. In fact, he felt nothing, like like he did last night on the bus.
Lisa wasn't so lucky though. This time the world itself didn't collapse in on itself, but she could feel her mind being ripped apart and built anew. Piece by piece.
As her mind was finally rebuilt from the bottom up she didn't really feel any different to previously. After all, she couldn't even remember having been transformed previously, so her mind being more accommodating to her changes wouldn't be noticeable to her. Not really sure what had happened, Lisa gladly kept on sucking her boyfriends cock. He'd already been close as it was, but as the changes hit her she paused for a moment, keeping her boyfriend on the very edge of climax. When she started back up Jim was finally given the final push.

This time Lisa wanted to savor his cream. Not letting a single drop spill she gladly swallowed. Finally sated she got up as if nothing happened and stepped into the en suite bathroom. Given the nature of their small apartment, it was the only bathroom, so Jim as left sitting on the bed waiting his turn. As he waited for Lisa to finish her shower he looked through the list of changes he'd yet to try. He made a text document of the ones that caught his attention and made a note for each one.

"My partner's butt is _____. If I could change her butt, I'd make it _____." - Wouldn't hurt to fix some of that sag, maybe make it a bit bigger..

"My partner's breasts are _____. If I could change her breasts, I'd make them _____." - Big titty goth girlfriend doesn't sound too bad? Should they be real or fake..?

"My partner's body is _____. If I could change her body, I'd make it _____." - Definitely a bit too chubby, I could make her toned and sexy. Or I could embrace the thicc and make her more of a bbw?

"My partner's sexuality is _____. If I could change her sexuality, I'd make it _____." - She's currently straight, which is fine, but I could make her bi and maybe convince her to do a threesome?

"My partner's dreams are _____. If I could change her dreams, I'd make them _____." - Not really sure whether dreams meant dreams as in sleeping, or aspirations.

"My partner's skin is _____. If I could change her skin, I'd make it _____." - Could be paler, to match her goth style. Maybe clear up some blemishes and birthmarks too?

"My partner's tattoos are _____. If I could change her tattoos, I'd make them _____." - Non existent, should maybe add some to match her new found style

"My partner's piercings are _____. If I could change her piercings , I'd make them _____." - Same as tattoos.

"My partner's intellect is_____. If I could change her intellect, I'd make it_____." - Dangerous territory, would be nice to finally be smarter than her (Jim's IQ is 91)

"My partner's kinks are _____. If I could change her kinks, I'd make them _____." - This could be interesting

"My partner's mind is _____. If I could change her mind, I'd make it _____." - Don't know how this would be different to mindset, but it's a free mental change if I need it

"My partner's piercings are _____. If I could change her piercings , I'd make them _____."

"My partner's Figure is_____. If I could change her figure, I'd make it _____." - Hourglass, pears shaped, straight as a stick or even round. Many options here. Should probably begin here before butt and breasts though.

"My partner's exercise routines are _____. If I could change her exercise routines, I'd make them _____." - They're not existent at the moment. I could make her work on her butt or something, get it nice and big. This would also give her a better figure. It's a bit long term, but it's basically a two for one. +I might get to see her in skimpy workout gear.

Stepping out of the bathroom, Lisa was wearing two towels. One covering her body, wrapped just above her breasts. Her hair was wrapped in the second towel. Considering how it had been drenched in cum just forty five minutes ago it was probably a real pain to get it cleaned. She beelined to the wardrobe and readied the outfit of the day. It was Saturday and the couple had no plans what so ever. That didn't stop Lisa from putting in maximum effort into her clothes though. Today's outfit consisted of the same black bra and mesh combo she'd been wearing following the first transformation. She picked out a fishnet tights that went up to her bellybutton. She also chose to go for a pair of black socks that went up to right above her knees. The outfit was completed by a pair of tight black shorts with lacing on the front thighs.

While his girlfriend was prepping her outfit, Jim sat eagle eyed. He really liked her new style, and was curious about what kind of clothes she now owned. Just before he went into the bathroom he got an idea. There didn't seem to be a very easy way for him to test out how his most recent change had affected his girlfriend. What he came up with was sort of devious, really. He decided he'd show his list of possible changes to Lisa, without the personal notes of course. If the change had worked as intended he should get a very different response than what he got when he came home the night prior.
He sent Lisa a copy of the possible categories he'd change about her and let her read through it and think while he went into the bathroom. Some twenty minutes later he came back out and saw Lisa in her outfit. To his surprise she was wearing makeup! He hadn't even changed her makeup routine in the app, yet here she was. With dark lipstick with a slight purple hue. Her eyes had matt black eye shadow with purple eyeliners. Looking closer Jim could tell she was also wearing colored contacts. Her pupils were deep purple! A lot of thought had gone into this look, obviously. There was a certain theme coming along here. Black and purple seemed to have become Lisa's designated color. As it would turn out, every single article of clothing she owned was either black or purple.

Was the makeup and contacts another side effect of the app? Did being accommodating to her changes also imply that she'd want to wear matching makeup and contacts of her own free will? This was great news! Now I don't have to waste a day on her makeup. Better yet, she thinks it's her own choice!

Stepping up to Jim, Lisa gave a sly smile and pointed to some text on her phone.

"..This one is fucking hot.. she whispered as she pointed to one of the options Jim sent her.
