Horny, Purple Demon Girl With Hooves on Halloween (Patreon)

Your shy girlfriend was possessed and turned into a winged, hooved, and horned demoness. She's said she's so fucking horny and needs you inside of her now. And if you won't fuck her, she said she'll find someone else who will.

So now you're about to fuck her in front of everybody at the Halloween party. Something that would normally mortify her but the demon inside of her is manipulating her hormones and emotions, making her so horny that it's consumed her. The demon can't directly control her, can't make her do something she'd never do. It can just prime the pump and let it play out.
