The First Encounter

When battling his rut Alastor runs into a very good smelling Lucifer, what will happen if his instincts take control?
⚠️DISCLAIMER⚠️ I respect that Alastor is aroace, I am as well (surprisingly), but 1) Aro people can have relationships and 2) Ace people can have sex. I wrote it in the way I think an aroace would deal with these urges, and I am welcome to feedback, but I don't want hate about Alastor being aroace.
