Awesome to see you writing again! The way you paint these scenarios and character, and the amount of descriptive language you use is always a joy to see. A shame about your old stories, but I'm really liking the direction this new setup is going, and the endless and gruesome possibilities for Delaney here. Definitely looking forward to seeing more!

Don't know if you're looking for suggestions or not, but I've got a few ideas for scenarios you might want to mull over, whether for this story or for future ones. Just some things I'd personally really like to see that might resonate with your particular tastes and I think would fit very well with Delaney's character and her sense of narcissistic cruelty.

- Delaney forcing Chase to full-on worship her as his god. Making him bow, pray, really sining praises to her, reluctantly or otherwise. Maybe make him tribute "offerings" to her by forcing him to masturbate to her and her feet. Whether the app is manipulating his libido or not is an option as well.

- Extending that god worshiping scenario, but only to her feet. Maybe shrink him so small and make him feel so insignificant that he's not even worthy of worshiping Delaney herself as a god, but instead to worship her feet as his god. Or even just one singular foot, or even a toe! Bowing, praying to, and praising the "Almighty Foot" or "Almighty Toe" as his ultimate deity.

- One scenario you've done in the past that would be great to see again would be forcing him to subsist entirely off of Delaney's feet. The only nourishment he's allowed to consume and live off of would be her foot sweat and various forms of foot waste. Maybe extend that to shrinking him micro sized and forcing him to live and survive ON her foot, like it's a huge, living landmass. Again, subsisting only on her feet's byproducts, the only air he can breathe is the smell of her feet, and having to deal with the seismic movements and deafening sounds her every minuscule movements make, turning her foot into an endless hellish landscape he's forced to survive in.

- Time dilation could be an interesting concept to mess with. Maybe force him to endure Delaney stomping and crushing him to death multiple time, and each time the amount of time he perceives going on for each stomp increases. One stomp taking an hour. Then a day. Then a week. A month. A year, and so on. And him being frozen and powerless to do anything, just watch and feel as his body is force to move and experience things in real time, while his mind is forced to perceive the whole dilation of time

No pressure or anything to use these or not. Just offering some scraps of inspiration. Either way, would love to see more from you! :)

Now that he has no limbs she could wear him as a pendant, or shove him up her butt, or tie him to her toothbrush and use him to clean her teeth
