I have, actually, it's the third CyLynn fic I ever wrote! I recommend going through my AO3 in general cause there's a lot! https://archiveofourown.org/works/47482924

She's never heard of it and Cy prays she never learns about it

No, but he has in the past tried to do things that usually trigger Lynn to see if she could get past it and... Nah. So he stopped.

It entirely depends on how old they are when she dies, but he's more likely to spend a lot of time staring at walls, yeah.

The main decision factor is whether Cy thinks Lynn is gonna get trauma/serious injuries from him ignoring her safeword. If it looks like she can take it, he's not gonna stop.

No "childhood event" at all, it's just the chemical reaction to the combo of him being attracted to women + feeling superior to the people around him + having a degradation kink. I think you have to keep in mind Cy is self-aware about his misogyny– he's aware the scientific studies out there prove women aren't any less competent or smart than men. But because he enjoys degrading Lynn, he joyfully leans into his misogynistic tendencies because it'll get both of them off, and because traditional gender roles are his vision of a good D/s dynamic. Engineering is also a very male-dominated field, so the culture is pretty different from your average work environment. Some of Cy's more unironic biases probably come from there.

Cy would never want her to fuck anyone else but him, and she wouldn't do it anyway.

Multiple things, really. Cy abandoning his engineering career for Lynn, the decision to marry Lynn itself, and the fact he's cheating on her. It's all infuriating to Alan.

Cy canonically freckles in summer! Elodie seems like the freckling type too.

She and Cy got really busy with work and figured it'd be nice to have this permanent reminder of their kinky relationship even when they don't have the time to do scenes!

Kinky pain can feel nice after the fact- it's just bruises, after all. Cutting, on the other hand, is generally more painful and also specifically a trigger for Lynn. Most suicide methods that aren't a bullet to the head can generally be excruciatingly painful, whether you succeed or not. Not the kind of pain Lynn can eroticize.

THEY ARE!!! It's why the Divorce AU feels so tragic. I think you'll love it even if it's depressing because it reinforces just how special CyLynn are to eachother

Like you said, Lynn's the one who comes the closest to being plural, but yeah it's not really like that for her.

Cy's misogyny is... complicated. It's half-ironic, but also kind of a core aspect of his personality, but also something he plays up both for kink and laughs, and also something he knows he's factually pretty wrong about.

As for penis size– it's funny you mention it, because I made a comic where Cy gets a little annoyed he can't reach Lynn's cervix past a certain point during sex. Of course, being a bit shorter than average (5.2") is nothing like having a micropenis or ED, but you get the vibe. He'd be generally annoyed, but not any less dominant. You have to keep in mind a lot of the kinky sex and D/s lifestyle Cy and Lynn partake in doesn't even involve PIV sex! Cy doesn't need a big dick to do impact play with Lynn, to do bondage with her, to get his dick sucked, to do puppy play, to do general Master/servant play, etc. So while not having adequately performing junk might hurt his ego a little, he's got plenty to do with Lynn that doesn't involve his dick. Also, Lynn's not really a size queen, I think she'd get over performance issues pretty fast just doing breath play with him.

No, because even if they stopped having kinky sex, they still have a clear D/s dynamic that's ingrained in them and their marriage. It would simply manifest in more vanilla ways.

Oh, they definitely do roleplay where Cy gets Lynn to wear "younger" clothing and she usually pitches her voice up to sound younger too. Usually he's fantasizing about students when they do that, or it's instead a fantasy of a younger version of Lynn. She herself doesn't care much for it, but she enjoys making Cy feel nice, so she indulges him from time to time.

Hahaha glad to know you like her! This one's not even a student, Cy probably picked her up at a bar, but I've got plenty more design ideas for students in my bag hehehe

Calling them "soulmates" would not be an exaggeration. Cy's the only person who's ever really gotten her, not just sexually but also emotionally. He relates to her narcissism, doesn't look down on her for it, and instead sees it as a sign they're peers. He's not in the slightest bit put off by her trauma, her needs or her personality. He's everything she wants in a man- strong, smart, dominant, and ultimately loving too. He's her rock and she knows she can rely on him to care for her whenever she breaks down, but also in her daily life. He's the guy who won't let her slip into alcoholism, who lets her be a puppy when she needs to unplug her brain, and the only person she's ever considered to be her intellectual equal. Lynn may have superficial "friends" but she's incredibly lonely at her core, and Cy is the only person who's ever managed to fill that void and make her feel like she's part of something beautiful. She needs a companion and Cy was born to be it. He has become an integral part of her and if anything happened to him, she would never feel whole again.

She'd be devastated and would need to be put on suicide watch. Thank God it'll never happen.

She'd wait for him.

Big brain... The level of mutual envy and jealousy would grow even more👁️👁️

I already have, actually, multiple times! Don't know when I'll post that publicly, but it's been available on my Substar for a while!

She finds it kind of sickening, but also weirdly endearing. She's more put off by Cy's general attraction to young girls than she is by him using her pics in particular. The fact she volunteered those for that specific purpose probably helps- she sleeps better at night knowing he's no longer looking at his students, and it's oddly flattering he was ready to delete all the pictures he'd accumulated of them just to look at her instead. Also, while Lynn had quite a happy childhood, she's very glad to be a grown adult, so she doesn't care much about her memories being used like that.

She also has a tendency to keep kind of... copies of herself at different ages in her mind? Some things she does to please her kid self, some things she does to please her college self, and some things she does to please her grown self. So while she's obviously not a child anymore, she feels that when Cy's looking at her childhood pics, he's looking at her.

All in all... A bit of a messy situation, but much preferable to Cy continuously collecting pictures of his students they might regret later, in Lynn's opinion.

He's not into drawn porn, it doesn't do much for him, though IRL porn doesn't either- he only likes women he knows irl.

Cy definitely makes her happy and she'd be miserable without him, so while it might not be a very healthy relationship, it's the best thing for Lynn.
