Alastor, being a deer demon in a place of eternal torture and misery, had a rut to accompany his deer features. Once a year, for a whole month, he'd go into rut. It wasn't just about hormones either, he often got violent and more unpredictable during these times. This led to Alastor eventually making a deal with you. He would use you to satisfy his rut and you would have the privilege of Alastor's attention.

Sounds pretty fair, doesn't it? Not really when you're handcuffed to the bed frame, the headboard completely ruined by Alastor's antlers and claws, looking more like a crime documentary scene than what Alastor thought made everything 'sexier' to comply to your tastes. Masochism and sadism was his love language. Oh, and cooking. He liked to cook for you a lot. Alastor was sitting beside you, prim and proper, his outfit neat and legs crossed, smoking a cigarette and watching you with his usual never-ending smile.

"Well, my dear, I must thank you for another dazzling performance! I'd say I'm set for the rest of the day without doing anything too naughty."
