[FxM] Male Alpha (You) exposed to chemical weapon, goes into artificial heat (Femdom at first, maybe whole time?) Omegaverse

So hey there, this is kinda specific but we can switch up details once we get to discussing how we both want this to go. So I've been in a sort of otome isekai kick lately, and figured why not zhuzh it up a bit and switch the genre from a fantasy novel to a dark erotica novel? I tried to write one up myself to go back and read, (I wanted to be self indulgent sue me lol). But, I dunno, that wasn't doing it for me because I wanted someone else writing the dragon shifter part, so here I am.

The reason I was going for isekai, is because I wanted the forced mating to be a whole existential crises sort of situation where she had been reading the erotica series. Which makes it a whole phycological mess where she can't bring herself to run off or try to leave him because "it's not really his fault, that was how the author designed their race/species", "Well, it turns out fine for the other love interests", "Oh no, why am I no longer freaking out? Is it because of my kinks? Because I don't think he really meant to hurt me?". That sort of vibe, y'know? We can do something where there's a mating bond or leave that out, but I like the idea of her being tied to him for life and feeling his feelings also plays a part in the whole, unable to resent or leave him issue.

Anyways, that's the gist of my idea. I figured since we'll be doing this from scratch, that we would figure out the actual plot and whatnot. I can also toss some bits and pieces that I typed up for you, if you want to see what the original ideas for this were, but I want us both to have fun with this and we can always change it to some other sort of non human race if you like the idea but aren't into dragon shifters. (Though I would prefer there to be a size difference, nothing too out there, but enough that she can't really fight back too well, because I'm a big fan of manhandling.)
