I started to get ready while she sat on the bed. I was cleaning up some stray hairs on my chin with an electric shaver when I saw her tail twirling behind me in the mirror. It was as if I had completely forgotten she was a demon. “You’re going to have to humanise yourself if you want to come to the party. Can you do that?” I asked, genuinely unsure.
“You want me to be selfish, arrogant, lazy, annoying, easy to kill and addicted to sex but bad at it?” she answered. She was a good actor, there wasn’t even a wrinkle of a smile in her expression when I looked back at her. Maybe she just meant what she had said. “I can do that. I can lose the tail and wings as well if it will make everyone else more comfortable.”
“You were the one who said you were a human so you’re all of those things as well.”
“I know,” she said proudly. “At least my succubus arc has made me good at sex.”
“So you can shapeshift?” I asked.
“That’s right,” she said. She got to her feet and walked over. I was focused on myself and didn’t catch her next question. Her tail moved up under my chin and turned my face away from the mirror. “I said, who are these two?”
I watched the tail with its sharp point snake away before looking at the posters on my wall. “Musicians,” I answered. “Just some people that I fancy.”
“David Duchovny and Gillian Anderson. Those were my first celebrity crushes. Are they still alive?” she asked.
I laughed. “Yeah, they are. Lucky for you. Big X-Files fan?”
“It started during my first summoning. We watched it all the time. I loved it and I loved them. I had to wait 20 years just to finish it.”
“When was that?”
“2013 or 2014 it would have been. Started it in my first full body summoning and finished it in my third.”
“They have released a couple more seasons since then.”
She lit up, eyes bulging out of her skill. “Are you fucking with me?” Her tail was practically wagging.
“Not fucking with you.”
“We have to finish it before I am gone. Don’t make me wait another 20 years.”
“Deal,” I said, as she rocked happily on the spot, back and forth.
“Do you want me to look like either of them?” she offered, returning to the posters. She was still beaming.
“Really?”
“I can look however you want.”
“No, it’s okay,” I said. That might be a little bit weird. I preferred her having her own face, even if that face was attached to a soul that I couldn’t explain. “You look fine like that.”
“Fine?” she said, a growl in her throat. I felt her tail again, this time against my cheek. She used it to caress my skin. She was teasing me, but the pointed tip of her tail was fiery hot. I ruined her good X-Files mood way too quickly. “You said fine?”
“You’re extremely pretty,” I said, repeating the term she had used earlier.
“That’s good enough for now,” she said, before making herself at home, rummaging through my drawers. “I need something to wear tonight unless you’re expecting me to go dressed in this.”
The charred hoodie with half its back missing wasn’t her best look. “My sister moved out a long time ago and she doesn’t keep anything here. My parents are away tonight so we might be able to steal something from my mum. She has some dresses that would probably fit you,” I said.
Lily stepped in front of the mirror. She took a deep breath, closed her eyes and then started to strip away the demon. Horns and tail shifted into nothing and then her skin started to lighten. Red became white, and she put her forearm next to mine to make sure the colours matched. She looked like a real girl now, a natural beauty who was shrouded in an unnatural allure. All and none of her was real, all at once.
“Can I go and pick something out?” she asked.
“Go for it,” I said.
She walked in the wrong direction as she left my room, but I left her to it and she found her way in the end. I got myself ready, putting on a pair of jeans and a plain t-shirt. We weren’t out of winter yet so it was still sweater weather, and I chose a navy blue cotton option that felt semi-smart.
