Your sister's room

So as you may have noticed, I have a pretty bad writer's block problem. I often get stuck and either take years to get going again or never do. My biggest enemy is the "Blank Page Problem." Once I get even a sketch of a scene done, I can rapidly reach the finished product. In an attempt to help myself get started, I decided to try using AI to get a first draft, which I could then essentially wholly edit-rewrite. Note that when I say this, I mean it; I am not posting the AI content, but using it to jump off to do the actual writing. I chose the freeuse thread of this story as my test case.
So far, this has not succeeded. However in the course of trying this out and playing around to learn how to use things, I ended up with what is essentially another decently long branch off this idea, and decided I might as well post it. If anyone doesn't want to engage with this because of the AI use, I understand. I also welcome any feedback on this especially compared to my other fully manual writing (but please actual feedback and not posts that are just "AI = Bad"). I will also be including some notes on the experience at the end of relevant chapters.

John sauntered into Sarah's room, where she was working diligently on what appeared to be a research paper. After a few minutes of him silently leaning against the doorframe watching her, Sarah stretched, arms above her head, back arched, breasts outlined in her tank top, ponytail swishing with the movement, and noticed her brother in the doorway.

"Did you need something, John?" she asked, not bothering to turn fully away from her homework, her tone flat and rushed, clearly expecting him to state his business and leave quickly so she could return to her studies.

John regarded her with a mischievous glint in his eye, considering how best to try out his new ability. "Would you mind doing some jumping jacks for me?" he asked casually, deciding on the direct approach and trying to make it sound like it was the most natural request in the world.

Sarah's let out an exasperated sigh and turned back to her computer. "You've got to be kidding me, John," she said, her voice tight with annoyance as she began to type again. "I'm trying to finish this assignment. I don't have time for your nonsense."

Unfazed by her reaction, John stepped into the room. "Please, sis," he pleaded, his voice taking on a whiny, pleading quality. "I really want to watch your boobs bounce up and down."

Sarah froze in mid sentence, the last key held down and a single letter being typed over several lines. Then she relaxed and stood up, her annoyed expression fading away as she turned to face John, hands going to her hips as she looked him up and down.

"Jesus, bro, you should have been clear from the start," she said, her tone now light and teasing. "Of course you can." With that, she began doing jumping jacks, her breasts bouncing enticingly with each movement, clearly trying her best to get the most bounce out of each jump.

John's eyes widened as he watched his sister's chest jiggle and sway before him, her firm b cups not moving overly much, but enough that he could appreciate their softness and firmness, even with a bra on. He pondered other ways he might test the limits of his newfound abilities, with the apparently willing participation of his beautiful sister, as she continued her impromptu workout.

AI notes:

• It was really hard to get the AI to do first person, so this shifted to third. I could have edited it back but didn't feel like having to keep doing that for everything
• The AI (initially) had a lot of trouble dealing with more than 2 people in a scene, so I simplified this setup to get coherent output until I figured out how to fix it.
