My bedroom smelled like incense. Six different fragrances. Five too many. I was lighting up candle number four when the smoke started getting a little overbearing and the fire alarm flashed into my mind. I closed my door and cracked open the window, just a little.
It was my first demonic summoning. I’m no expert but potentially burning down the house felt like bad vibes. My parents wouldn’t like it, but perhaps the demons would. Mixed emotions.
I had to print out the script for the ritual because I couldn’t memorise it and the computer screen was just a little bit too far away. We didn’t even have any ink in the printer so I had to go and buy some. I bought the candles and the incense and the sigils and it cost me almost £60 all in but it would be worth it if this succubus that I was trying to inhale into my body was able to siphon some of her sexual energy and confidence into me.
How did I convince myself to do this?
Half the answer is pretty easy. The reviews are great. It seems like everyone who succeeds in their summoning goes on to have a pretty good time with it. The world stopped pretending the occult was fantasy, and now it feels like everybody and their mother has summoned a succubus or talked to a ghost. I might be exaggerating a little. The internet tells me that most summonings still fail, but succubi and incubi are now just an accepted part of reality. If you show up to a party at the weekend and one of your friends doesn’t look himself, then there’s a real chance he’s got a demon pulling the strings from within.
The other half of the answer is actually quite easy too. A bit of desperation and a bit of cowardice. I’ve fancied Alice for a long time and our time together in sixth form is almost up. There’s no doubt we’ll still be friends long after our exams, neither of us are moving away and we’re even going to the same university, but the campus is spread around the city and we won’t have as much time together then as we do now. It might not be now or never, but now is preferable, and the prospect of never fills me with constant dread.
I wish I could just tell her how I feel. I don’t know why it’s so hard. I suppose it risks everything we already have, all those years of friendship. Fear of rejection is a real motherfucker. I don’t want the succubus to seduce her for me, or use any of their powers to manipulate her desires. I just want them to help me say the stuff I want to say and if things went surprisingly well from there, maybe offer some in-game guidance on how to roll my hips in a way that might actually be pleasurable for her.
A little bit stupid. A little bit ridiculous. And yet here we are.
I’ve never shared my body before. I can’t even imagine what it feels like. If she’s one of those nice demons and she knows how to chat up a pretty lady and swing some dick around, it’ll probably work out. That’s assuming Alice likes me too, which I think she does, but maybe she doesn’t, and that would be sad. I think the incense fumes were getting me high.
How’s a guy supposed to dress for a summoning? I don’t have any gothic attire but standing inside a summoning circle in running shorts and nothing else felt a little bit disrespectful to the underworld and all of its inhabitants. I was lying to myself too, pretending I was going to go for a run after getting home from school. I needed to get the stress out somehow, but decided a wank was more fitting.
I was close to starting the ritual when the cat pushed his way into my room. “Get out of here, old man,” I said, chasing after him. He moved in slow motion. Salem is the oldest swinger in town, named in honour of the cat from Sabrina the Teenage Witch. He was alive when that show was airing and he’s somehow still alive now. Mum was a witch wannabe in her youth. It wouldn’t surprise me if she somehow managed to extend his life with one of her spells. “I’m not turning you into a succubus. Mum will shout at me.”
He scratched at the door from outside, unforgiving in nature.
I returned to the supernatural, standing on the edge of the salt circle and looking down at the spell. It was written in Latin. The rough translation is about a sharing or bonding of the soul with a mistress of darkness until our union succeeds in fulfilling the contract that joined us. The guides I found online said that I have to start stating the terms of my contract when the room starts shaking and the salt glyphs glow a shade of red that my eyes have never seen before. Spooky. A little bit horny too, if we’re being honest.
It felt nonsensical but I knew it was real. I suppose the final hesitation came from the knife in my hand. I had never had to cut myself open before, but I gritted my teeth and swiped the blade across the pad of my thumb. The cut started to throb instantly. I recited the words on my print off, careful with the pronunciations as I let my blood drip onto a sigil in the centre of the circle.
The room started to shake and the glyphs started to glow and I heard faint whispers in the distance. The whispers became screams, smoke rose all around me and a blackness swept over the room despite the light outside. Fucking hell, it’s actually real. Not only real, but ludicrously easy.
A demon was about to enter me. Crazy thought, and yet so natural. All because that one politician got caught and pulled back the curtain because he didn’t want to get impeached. The world accepted their presence, comfortable in the knowledge they served us and not the other way round. I grew up knowing succubi existed but I never thought I would indulge. Alice was worth the change in approach.
“What do I do?” I asked nobody in particular. The screams kept screaming. I wasn’t scared. I had never read about a summoner being sucked away so as crazy as this was, it felt safe. The light of the previously salt glyph formations turned black, and it was like staring into a neverending abyss. It was as if my bedroom floor was gone and if I stepped forward I would never stop falling.
“Alice Crawford. She’s my friend. I just want to tell her how I feel and I am summoning you to help with that. Nothing crazy but it would be nice to just have a bit more confidence in what I want to say, or a little bit of help with sex if it comes to that. It probably won’t, but it would be pretty cool if it did.”
Jesus Christ. I’m chatting to the demonic wormhole as if it’s my mate. The crazy thing is I’ve never told anybody how I feel about Alice. It felt nice to let it all out and the words kept on coming.
“She’s really sweet so we have to be nice to her. I guess it matters to you that she’s hot as well. I swear she’s getting hotter every day. She’s really coming into her own these days. She wore this new dress recently and it was next level, honestly, you should have seen it. Maybe she’ll wear it tonight.”
Tonight was an 18th birthday party at Elira Holloway’s house. The party and my parents being out of town for the night felt like everything came together at the right time for a summoning. I couldn’t wait to see what Alice was wearing. She has been growing in confidence so much since she turned 18.
Even just thinking about her was getting my dick hard and my hard dick started thinking about other opportunities.
“Alice is the priority. She’s my endgame, but listen, if she’s not interested and she just wants to stay friends then we can rebound on Poppy and see if she’s up for it. She’s really hot too and she has some experience so you might like her.”
“I’m not going to say Grace. She’s pretty too but Mason really likes her and one day he will work up the courage to tell her. Or maybe he’ll just summon a succubus to do it for him.”
I couldn’t stop yapping. My dick was rock hard and suddenly the possibilities were endless. This succubi shit is real and it felt rude not to take advantage. After all, there’s nothing wrong with having backups.
“Miss Bishop? She’s one of my teachers. If we’re feeling crazy then that one would be fun. I fancy her so much. Do you need her full name? If you do then I don’t know it, sorry. You’re not going to answer me, are you? Is this even working?”
“Miss Evans too, I guess. She’s a bit mean but that can be pretty sexy. There’s the new PE teacher as well. She just joined and I don’t know her name but she is really hot. Sue the dinner lady?” I said, and it was like a question. Maybe I couldn’t believe I was saying it, but I always had a thing for her. It was the perfect time to admit it. “I don’t know if she’s married.”
“Elira as well. It’s her party so it would be a bit rude if she wasn’t on the substitutes list. Jess, Lauren, Megan,” I continued, and it was starting to get silly. “Natalie, Aimee, Maeve. These are all from school by the way.”
I kept listing names, some of girls that I barely knew as people but definitely knew as local hotties. My dick was on the prowl, thinking and naming on my behalf. It spotted a couple of posters on my wall, and suddenly the gaping wormhole in my bedroom floor was being told about my celebrity crushes.
“Olivia Rodrigo and Chuu from Loona. Let’s be realistic for a minute, none of these girls are going to want me, but especially those two,” I said, and I didn’t know if I was talking to the demons or to my demon-powered dick.
“My friend Mason, by the way. His mum and sister are really hot,” I said, laughing to myself. I was going crazy, fueled by the ridiculous position I found myself in. “Okay, that’s too far. Most of those were jokes anyway. I really don’t know what I am supposed to do to end this but if it doesn’t end soon I am going to name every woman on the planet.”
