Unless I'm forgettingan old threadfic, I donnnn't think this was me? In the one dadson murder husbands AU I have, it's Alastor grooming Vox, not the mom. It's still up on my Ao3 and all of my relevant arts are linked. I just had to delete them from my bsky out of caution U-U

Ah, it was an old threadfic (pre s2, if that matters). I'm pretty sure it was you, because I wasn't following anyone else at the time that would have written it. I'll just elaborate on the details to see if it sounds familiar.

cw incest, grooming, noncon

Alastor was kind of a neglectful or distant parent to Vox, I believe, so his absence made it easy for Vox's mom to swoop in and groom him. She'd get him to do things like eat her out or fuck her. This was a Vox who was reeeally young, like under 13 young. One day, Alastor finds out about it, is rightly horrified, probably kills her? and finally steps up to protect and take care of Vox. Because he's a wee bit fucked up, they still end up in a romantic/sexual relationship, but waaay more consensual than Vox/his mom. They're still a murdering duo, but I think they went strictly after rapists or groomers, considering everything.

I remember there being a note that despite Vox being naturally bisexual, he's kind of traumatized out of interacting with pussy, or something of the like? I think there was also a branch of the AU where the mother's sister also was involved, or had been attracted to the mother? There were kind of two other characters aside from Al and Vox who were down in Hell with them. I'm sorry if this isn't actually yours, but I have a distinct memory of it! 😭
