Summary
Rice Shower's Classic Year was supposed to be her moment with two legs of the Triple Crown down and one to go. For the first time in her life, she thought she might actually be someone worth believing in.
Then she lost the Kikuka Sho.
Now she's back to being the jinx girl with too much body and not enough courage. Her trainer is patient. Her best friend Haru is relentless. They haven't given up on her, even now. The harder part is Rice learning to believe she's worth staying for.
Haru has always been good at giving Rice what she needs. What she wants is a different question. But if Rice is ever going to stop hating her body long enough to tell her trainer how she feels, someone has to show her it's worth wanting first.

The wine was never the point. It was just what Willow drank to keep the other thing buried: the want that's been aging in her for years, concentrating in the dark like grapes left on the vine past reason.
Weiss has been staying away because she knows what she's thirsting for. What's been fermenting between mother and daughter is overripe. The cork is finally giving way and nothing will catch what spills.

Summary
Zhu Yuan joined the force to protect the public, but all she really offers is a useless cock and a body made to be used. In this collection, she’s forced to serve in the most degrading ways, humiliated by both the civilians, criminals, and people she once swore to protect.
Her badge is a joke, her authority a lie, and her tiny, twitching cock betrays her every time. The city doesn’t need her strength: only her mouth, her ass, and the pathetic little thing between her legs.
Each piece is standalone unless otherwise noted.

Summary
"Assessment of organic reproductive response." That's what she called it.
In the Bunker's archives, they're filed alongside legitimate reconnaissance reports: sector sweeps, machine activity assessments and threat analyses. No one reads them or questions why a combat android keeps requesting patrols in sectors with no strategic value.
But 2B keeps submitting them. Field report after field report. Each one more depraved than the last and documenting another step in her transformation from combat unit to something YoRHa never designed her to be.

Summary
Cyrene and Caelus' marriage was unavoidable. Necessary: the very fate of Amphoreus rested upon it.
But it broke a promise, one he'd made long before he even met Cyrene. It doesn't matter that Firefly's over it, that she's forgiven the both of them and understood the circumstances; guilt still roils in the core of Cyrene's being. She's branded herself a thief and feels she's never properly atoned for her "Crime".
So, naturally, she proposes an elaborate and kinky threesome between her, Firefly, and Caelus to assuage her guilt, and perhaps wring out any lingering feelings of resentment that swim in Firefly's heart. And if Caelus can overcame his own angst and guilt about the whole scenario... well, we'll just call that a bonus.
XxX
This is a spinoff of Bend, but Never Break. Knowledge of BBNB is not required, and not even very useful, because this takes place in a hypothetical future timeline of the unpublished and still In Development Reboot. It's a smutfic with a decently simple plot explained in the actual text of the story. It's got kinky yuri in chapter 1 and a kinky threesome in chapter 2 (and beyond). You'll probably like it if you like those things.Series

Bookmarker's Notes
Words cannot describe how amazing this work is in what it does and tries to convey
Commented (Chapter 1)
First off: I'm taking full credit for the abductor machine and you can't stop me. You took that throwaway suggestion and ran with it so hard that now I can't imagine the scene without it. My only suggestion is that you should have had Firefly lick the seat clean afterwards.
Same goes for the armpit thing. I'm really glad you let me talk you into actually writing it out instead of just having Cyrene think about it. She gets her treat at the end and Firefly pretends she's not equally into it while literally stroking herself off. That was a masterful add; I might be yanking that for a future work 😉
But the real standout here is the emotional core. I know I said it before, but I'm saying it again. This is a Firefly and Cyrene story; Caelus is just a catalyst. The conflict lives between these two women and extending the gym scene out to give them this whole chapter to themselves lets that breathe in a way that really works.
That emotional focus pays off in the moment where Firefly stops everything and refuses to let Cyrene self-deprecate. Holy shit. Her being able to see through every layer of Cyrene's bullshit: the horniness, the begging, the "use me like a cheap fucking onahole" deflection, and going straight for the wound. She doesn't let Cyrene hide behind being a toy; she cuts right through all of it to tell her she's worth this and more. Being able to pull such tenderness and emotional depth from a character who literally brings an emergency strap-on with her everywhere she goes is incredible.
I think it's no small feat to have me, someone who doesn't really know much about Honkai: Star Rail and hasn't read Bend, but Never Break, gushing about this side story: you are executing these ideas and concepts so well.
I cannot wait to see how you push Cyrene and Firefly to their emotional breaking point in Chapter 2. Also, you really should write more yuri 😉🫶

Summary
Amber and Collei are now a married couple, but not a traditional one. Their wedding rituals were quite unique and magical, leaving them with a new lifestyle that now they’ll share together: That of constantly and perpetually having anal sex together.
Let's find out how they manage...

Went back to reread this and you have me hooked for another chapter ☺️
I really loved all the worldbuilding here, especially the little ways Amber and Collei now have to adapt their lives. It makes the ritual feel so much more real and I love that figuring all of this out together feels genuinely important to both of them rather than just a series of inconveniences they have to work around.
I also really like the contrast between Amber's confidence and Collei's uncertainty: Amber is so sure they'll figure things out and seems genuinely happy with the life they've chosen. On the hand, Collei keeps having these little moments where she wonders what this means for them and whether Amber really wanted all of this for herself. It'll be really interesting to see where you take that doubt and conflict! I can't help but wonder if we'll get one of those "hard days" where their new way of living doesn't quite go smoothly or maybe Collei finally asks Amber how much of this was really for her 👀
Keep up the good work 🫶

Summary
An idea popped into Sandrone's mind—a bold one, for certain, but one that almost guaranteed Columbina wouldn't be able to hold up her end of their makeshift agreement. If she was lucky, it might even get the woman to leave her alone entirely. She reached for a spare piece of the nice paper she kept on hand for official use, and began writing out the exact procedures her little "experiment" would entail.
Sandrone proposes a deliberately outrageous experiment in order to get Columbina to stay as far away from her as possible. She does not succeed.

This hit every single thing I love. The tags told me I was in good hands from the start and the premise, Sandrone designing an experiment to scare Columbina off and then being too stubborn to back down, is such a perfect setup. I love trans Columbina here, especially that she's lacking in size. It's so cute and it pairs perfectly with the overstimulation and the handjob focus. Sandrone saying "I thought these were supposed to be bigger" while lazily stroking her had me grinning.
What really grabbed me is the emotional throughline underneath all of it. I love how Sandrone's spiral works because she genuinely cannot identify what she wants. The question keeps coming back to her and she keeps deflecting. She escalates not because she's confident but because backing down would mean admitting something she can't name. The clinical language is the only framework she has, and "This was absolutely not the plan." while she keeps going anyway is just perfect tsundere self-delusion.
And Columbina is the perfect foil because she's quietly steering the whole time. I love how her serene compliance never gives Sandrone an excuse to back out and thanking her every time almost coaxes her deeper. She sees right through Sandrone; just needing to suggest and Sandrone will comply because she has no defense against someone giving her permission. I wouldn't be surprised if Columbina suggested kissing might lead to better results and then Sandrone immediately shoves her tongue in her mouth, insisting it's for the experiment. They both know what's happening, but the plausible deniability is the whole point.
The work is also genuinely funny while still being hot: that's such a hard balance to strike and you execute it perfectly.
I'm excited to read the rest of your works! Thanks for writing this 🫶

Wise fucks Nangong backstage, and, in return for all the brattiness she sends his way on a daily basis, decides to play a public prank on her, just before she goes onstage. Sunna is apalled.

Soul, this was so good! You utterly capture that bratting dynamic. They keep pushing each other into being bigger messes and falling harder. Wise keeping his cool while Nangong wiggles and whines, then she completely losing it the second he actually gives it to her 🤩 They are a perfect match.
And it works because underneath all the teasing, there's real tender love holding it up. That flashback to Nangong being terrified he'd leave once he understood what dating an idol meant and Wise just holding her and promising to stay gives all the smut so much weight. They can play rough because they both know the other isn't going anywhere. To them, the bratting IS their love language.
Hair down Nangong is so cute! Wise undoing her ties right before she goes on stage and her choosing to stay like that is fantastic. With how much Wise clearly loves that silky curtain of hair down her back, it really makes me want to see a hairjob in the future 👀
Also absolutely love the part where Wise whispers about her fans going home and touching themselves thinking about her. Nangong getting wetter just imagining it as her shame and arousal mix together? Incredible 🫶
Honestly, I'm wondering how far these two will push the risky public stuff. What's next after backstage-before-a-show with cum taped inside her? They're clearly nowhere near done testing limits 😉

I really love your take on Dialyn here! She can’t actually voice what she’s feeling, but you still make her love for Banyue so obvious through everything she does. And I love that Banyue struggles to put his own feelings into words, so they’re both trying to communicate something they don’t quite know how to say.
Such a good read; thanks for writing this! 🫶
