Alastor and Husk have had sex before, because Alastor didn't like not knowing something that could be (potentially) used against him, and Husk is the only person he trusted in such a vulnerable position.
It was awkward but it was fine. They don't talk about it.
(It somehow came up once to Angel when Husk was a bit too drunk to remember why telling someone this info was a Bad Idea. Angel asked how sex with Smiles was like. All Husk will say on the matter is "he bites," and provides absolutely no more information.)
Alastor and Vox have ALSO had sex before, but that was just so, after Vox finished, Alastor could tell him he was bad at it and emotionally destroy him.
(Alastor wouldn't have considered going so far if Vox didn't suddenly attempt to push him and his boundaries so far and try to force him into a subservient role at his company. So he decided "fuck it, this is the best way to get him" and does this to him immediately before he disappears for 7 years.)
Another AO3 thing I’m curious about, how do yall decide if something is good enough to read? Usually I follow a rule of 1 kudos for every 10 hits. One because it’s easy math and two it’s yet to fail me. Thoughts? Do you just go for it and pray it’s good?
