demon!billy: oh i’m gonna have so much fun with this deeply repressed pretty boy, gonna get him panting and desperate for me and bounce him on my dick in no time
also billy, after months of secretly kissing the taste of ice cream off steve’s lips and massaging aloe into his sun burned skin and singing along to the radio with him while watching the wind whip his hair with the highlights sparkling in the sun and steve’s laugh filling up his entire chest, being overcome with the desire to keep him forever: fuck.
Little Steve Harrington is so lonely he tries summoning a demon with a ritual advertised on TV--but luckily, it doesn't work, and a buff, non-human nanny hired by his mom shows up minutes later. Years later, they're best friends, and Steve still doesn't know the truth. For @magniloquent-raven!
When his dad finally locked him out of the office, Steve spent the morning sitting in the hallway playing with his Legos. When his stomach growled, he knocked quietly, and his dad’s voice on the phone continued, so he went in the kitchen to forage. He found Cheez-its, and olives, and a tightly wrapped triangle of gooey cheese that tasted good in the middle, but had gross, chalky skin, so he licked the middle out and stuffed the rest down the side of the garbage.
He walked back into the front room and flipped the TV on, just to make some noise. “In the future,” came the syrupy voice of the man on the screen, “—we’ll have robots to be our helper-friends!” He chuckled to himself, leaning back in his leather chair, and folding his arms on his huge wooden desk. “But that doesn’t work for us now, I hear you say.”
The camera zoomed out, and he waved to a woman with curly hair and long fangs, sitting on the edge of his desk. She was wearing way less clothes than the man was, and Steve frowned, wondering whether she was cold. “Our summoning spells are assembled by real lawyers, and airtight!” the man said, and the woman nodded, smiling, and holding up a picture with a lot of numbers and lines. Steve squinted at it guiltily—he’d seen the man’s ads before, and he mostly remembered the picture, probably.
The helper-friend lady looked nice, he thought.
“Too good to be true? We even include offerings! Bat eyes, tears of the innocent—” he said, smiling and holding up jars, as ‘ethically sourced from internment facilities’ scrolled across the screen.
Steve frowned around, and then grabbed his LEGO 1969 Chevrolet Camaro Z/28, the most complex set he owned.
“Honey,” the man told the woman on screen, and she opened a can of soda, and poured it over her own head, still smiling. “Perfectly compliant,” he said. “And just wait, there’s more! Any purchase comes with a matching, complimentary summoning sigil for a protective home guardian! Just drip a drop of fluid—” he winked at the camera, and it showed something red splashing across the page, as his voice suddenly screamed “Augh-no! Don’t—”
Steve had already grabbed the remote and hit the fifteen-second replay, and began drawing out the picture. He hit it again and again, coloring in different colors, and wishing people in commercials didn’t always yell. He drew the circle carefully with a piece of thread from the long fringe on a throw-blanket he wasn’t allowed to mess up, then folded it carefully again, grimacing. He colored in the crosses with a different color so it looked nicer, and drew the little castle wall-looking-bit. He added a horse.
When it came time to drip fluid on it, he clicked the TV off, and got a juice box from the fridge, figuring apple juice was way less gross than blood, and it wouldn’t ruin his picture.
Steve stared at the picture, holding the juice box, and thinking. He imagined not eating alone. He imagined the nice lady smiling at his Legos—maybe she’d like the castle set, he thought, like in her picture. He’d just summon her for a little, he thought—just a few minutes, enough to make them both a PB&J.
His stomach growled—again—and he frowned at his dad’s office door, sighed, plonked the Camaro in the middle of the picture, and squeezed the juice box to spray over it all.
Nothing happened. Steve stared at the picture for a long moment, his eyes welling up with tears, and then kicked the couch. It felt like his foot broke from the impact, and he spun around in a circle, muttering a lot of words he wasn’t allowed to say in the house. He hopped into the kitchen, sniffling, and got out the peanut butter, jam, and a spoon—but instead of getting the bread, he sat on the floor in front of the sink.
He felt a sinking sensation of guilt as he stuck the spoon right into first the jam, and then the peanut butter, sticking the whole spoonful straight in his mouth and licking it off. Once he’d licked the spoon, he stuck it back in the jar, his heart pounding. The peanut butter was crunchy and salty, and the strawberry jam was stickily sweet. He wondered whether his mom would check the bread and know, and cried harder as he chewed, hugging his knees.
The floor in the front room creaked, and he startled so hard the spoon jabbed hard between his upper molars. He scrambled to his feet, fumbling the lids back on the jam and the peanut butter and shoving them under the sink, his heart thudding in his chest, but nobody came in.
The couch squeaked softly, and Steve edged to the doorway, the big spoon hanging forgotten from his mouth, to see a tall man with horns and no clothes at all lying across the couch, right up against the forbidden throw blanket. He raised his eyebrows—they had shiny jewelry in them—and breathed out smoke, indoors, as he looked up at Steve.
He then yelped and scrambled to fall with a thud over the back of the couch. “The fff—what are you doing here, kid,” came his voice, from behind the couch. “Where the—where on earth are your parents?!”
“Unhm,” said Steve, who hadn’t ever seen a man wear so much jewelry before, and wondered how much it hurt to have jewelry in your dick. He took the spoon out of his mouth. “Uh. Dad—dad is—in there,” he pointed vaguely toward his dad’s office, his eyes still fixed on the horns sticking up past the back of the couch. “Do...do you want me to...get him?”
The naked man popped up behind the couch again, looking kind of mad, and Steve stepped further back, watching the golden chains and jewels glint in the light from the window. “...you look very pretty,” Steve said politely, and the man groaned, grabbing the blanket as he stood, and wrapping it around his waist like a towel.
“Why the—why are you here,” he hissed, and Steve swallowed.
“I’ll go in my room,” he tried to say, but it came out kind of a weird whisper, and he realized he was starting to cry again, so he turned away, and the man scrambled from behind the couch.
“Wait! Kid,” he said, and Steve stopped to see him step and spin kind of gracefully around the glass coffee table without catching the blanket on it. All his nails were pointed, and painted black. “I’m sorry—” he cut off, staring down at Steve’s picture, and the LEGO 1969 Chevrolet Camaro Z/28.
“...what’s this,” he asked, like maybe he was mad again, and Steve wondered, suddenly, whether his mom had forgotten to lock the door, and the man was a naked burglar, looking for clothes to steal.
“I wanted to meet the TV lady,” Steve admitted, trying to take it, but the man snatched it up. “Um, are you—are you a burglar?”
“Am I—” the man glared at him—his eyes looked like fire, weirdly, the blue fire on the stove—but he didn’t look mad at Steve, yet, so Steve just bit his lips together. “...you drew this?” the horny man asked, more quietly, and Steve nodded. “Why?” he asked, and Steve knew he was in trouble—even if the man wasn’t supposed to be there, grownups always told each other when Steve did something dumb, like steal the TV man’s picture, which was the point Steve realized he was a stealer, a thief, like on TV. America’s Most Wanted, he thought, his heart pounding.
“Why draw this?” the man asked softly, crouching down, and Steve sniffled again, wiping his eyes.
“He said a friend would come,” he admitted, wondering whether kids had their own jail, or whether he’d be in the one with all the guys from movies, who chased teenagers with chainsaws and knives.
“You wanted a friend?” the man asked, but even softer, and Steve nodded, clenching his fingers in the sides of his pants.
“I didn’t mean to steal it,” he whispered. “I won’t do it again.”
“...okay,” the man said. “Don’t—don’t cry, it’s okay, are—are you okay?” he held his hands up like he was gonna touch Steve’s shoulders, then crossed his arms, frowning.
“I’m okay,” Steve nodded, wiping his nose on his sleeve. “...are, um,” he asked, cautiously, “—are you supposed to be...in here?”
“Uhhh,” said the man. “Definitely not naked, right?” he laughed, kinda nervously, Steve thought, and he snapped his fingers. The throw blanket turned into shiny fringed pants.
“Ohhh,” Steve whispered, impressed. “How’d you do that?”
“Oh,” the man said, grimacing. “Um, let’s talk about you summoning demons, okay?”
“...okay,” Steve nodded, sighing, but then a thought occurred to him. “Uh, do you want a PB&J?”
As they ate, the man spread Steve’s picture on the table, with the LEGO 1969 Chevrolet Camaro Z/28.
“So this is a circle to summon the demon Belial,” he said, low but kind of intense, like Steve was in trouble, but mostly he looked sort of worried.
Steve swallowed his bite of sandwich. “...it’s not exactly the same,” he pointed out, a little sulkily. “I added a horse.”
“...so you did,” said the man, turning it to look. “...look, summoning demons is very dangerous—”
“My dad says there aren’t bad demon summoners,” Steve told him. “He says there are bad plumbers, and bad strippers, but if you’re talking to somebody, and they summoned a demon, they must be good at it, because you’re talking to them, and—and he was on TV—”
“Strippers,” said the man weakly, and Steve realized he was being rude to his guest.
“I’m Steve,” he said. “What’s your name?”
“...Bel,” said the man, then, hurriedly, “Bill?”
“My mom likes Billy Idol. And Billy Joel,” Steve suggested, and the man nodded.
“That’s a normal name that I definitely have,” he nodded, grimacing, “—Billy, I’m Billy.”
Steve considered this.
“Are you listening, though? About demon-summoning? Even a lot of adults have a hard time with it—” Billy started again, holding Steve’s LEGO 1969 Chevrolet Camaro Z/28 to his chest like it was a present for him.
“The guy on TV said it was for a helper friend,” Steve told him, feeling a little guilty, but really not too much, since it hadn’t even worked.
“Steve,” Billy said, pressing his hands together over his mouth. The chain hooking his earring to the ring in his lip swayed and made a bell sound, and Steve stared at it, then remembered to nod. “Okay,” Billy said. “Could you promise me you won’t try to summon any more demons?”
“My dad says—” Steve started, again, but he cut off guiltily as Billy slumped back in his chair, groaning.
“Look,” Billy tried again, rubbing his face. “Summoning demons isn’t like inviting somebody over, okay? They have to come. Now imagine if someone called you up to—” he frowned down at himself, biting his lips with pointed teeth, and cleared his throat. “Uh,” he said, swallowing, and snapped his fingers with both hands—and all the jewelry vanished. Even his cool horns were gone, Steve realized, and he had clothes on, a little tiny black shirt that showed his belly button, and shiny plastic-y silver pants.
It was disappointing, but Steve looked into Billy’s flameless eyes and blunt-toothed smile and politely said “...you still look nice...I guess.” Billy snorted a laugh. “...I’ve never seen pants like that,” Steve offered, and Billy frowned down.
“What’s wrong with them?” he asked, then shook his head. “No, wait. Okay. What if you don’t want to go somewhere—”
“People make me go places all the time,” Steve said darkly, remembering the week before, when his mom had drug him in for a haircut that made him look like G.I. Joe. He rubbed his still-fuzzy head, glowering.
“Uh,” Billy said, trying not to smile, but spinning the tires on the LEGO 1969 Chevrolet Camaro Z/28, and Steve was a little proud that he liked it so much. “Okay, a stranger. What if a stranger makes you go somewhere you don’t want to go?”
“That’s kidnapping,” Steve said, breathlessly, his eyes huge, and Billy pointed the LEGO 1969 Chevrolet Camaro Z/28 at him.
“Yes. When you summon a demon, you’re kidnapping them, okay? And they can’t leave unless you let them go.”
“But the man on the TV said—” Steve whispered, then stopped, remembering how he’d made the almost-naked woman pour soda on her own head. Steve covered his mouth, suddenly realizing she might not have wanted to be almost-naked, maybe the man had taken her clothes off, like Steve with a doll. “Oh no,” he whispered. “I’m so glad it didn’t work!”
“Ah, yeeeah,” Billy said, grimacing.
“Um,” said Steve, reaching a hand over to retrieve his prize LEGO kit, and Billy snatched it back. Steve narrowed his eyes. “You were looking for my parents, but my dad didn’t say you were coming over, are you my mom’s friend?”
Billy winced, grimacing. “Where is she?”
“She’s at work,” Steve told him. “Daycare is too expensive, so over the summer I have to be good.”
“Wait, are there any grownups here?!” Billy asked, looking horrified, and Steve nodded, pointing down the hall again.
“My dad. He locks the door.”
“...What if you drown in the bathtub, or try to eat your own fingers, or something,” Billy breathed, and Steve glared at him.
“I’m not little,” he hissed, sliding forward in his chair a little, so his toes reached the floor. “I’m not a baby.”
“You don’t need a friend, you need a nanny,” said the recently smoking, horned, pierced and tattooed man before him. “And that’s, uh, that’s why your mom sent me.”
“...did she really send you?” Steve asked, narrowing his eyes, and Billy crossed his arms on the table, hugging Steve’s LEGO 1969 Chevrolet Camaro Z/28 against his chest.
“Yeah. Yeah, she did,” he said defiantly, and Steve relaxed a little, because Billy sounded like a teenager, just a bigger kid, really. “She said to put less peanut butter and jelly in your sandwiches,” he pointed to Steve’s overflowing PB&J-bread-burrito, looking smug, “—and just make another sandwich.”
Steve gasped, staring at him, and feeling absolutely betrayed. “You tricked me! Why’d you let me make it!”
“It’s okay, I won’t tell,” Billy said, and Steve’s heart was won.
Billy won it further when he scooted his plate aside to admire the LEGO 1969 Chevrolet Camaro Z/28, and Steve drug him back to his room to show him the kits he had. “Come on,” he said, excited and rude, and Billy slowed way down, grimacing, and flickering back to his pretty bejeweled self, with horns.
“How about you ask if I wanna do things,” he said stiffly, slowing almost to a stop, and smoking more around the eyes.
“Oh, yeah,” Steve nodded. “Sorry. Can I show you my room?”
“Or maybe, ‘Hey, Billy, want to see my room,’” Billy suggested, taking a deep breath.
“Okay,” Steve nodded. “Want to see my room?”
“Sure,” Billy nodded, relaxing like it was some big relief.
It occurred to Steve maybe it was. “Sorry,” he said quickly. “I’ll be polite, I won’t get you fired.”
“Um, yeah,” Billy laughed, shaking his head. “Maybe don’t, uh, order me around.”
“Yeah,” Steve nodded, thinking hard about it, so he’d remember. “I won’t say ‘Billy, pick me upOOF—” he wheezed, as Billy yanked him into the air with one arm around his waist. “Sorry,” Steve wheezed, his feet kicking. “I-I’ll say Billy would you, sorry—”
“Shit! Damn it, I mean, uh, sorry,” Billy said, grimacing, and sat Steve back on his feet, straightening his clothes.
“I’ll remember,” Steve told him, wide-eyed, and then, because Billy looked guilty, “It’s okay.”
He tried hard to remember, and he usually did, because Billy got all tense and weird if Steve forgot, like he was trying to move underwater, and Steve had to yell “If you want! If you want!” as Billy grimly bit into the crunchy, burned eggs Steve had made.
“That was disgusting,” Billy told him, that time, and Steve couldn’t stop laughing, waving his hands.
“Okay, okay, can I—can I just tell you you can ignore me? I won’t tell, you can just—just do things if you want to—”
“...you sure about that?” Billy asked, snorting softly, like Steve might be kidding, and Steve nodded frantically.
“Yeah! Yes! Don’t, um, don’t eat any more eggshells, I’m sorry!”
“...okay,” Billy said, smiling down at him. “When am I not supposed to listen?”
“Uh,” said Steve, blinking at him. “I mean. You should—you should always listen—”
“Yeah, that’s what I thought,” Billy said, rolling his eyes.
“No, you should!” Steve told him, grabbing Billy’s hand and tugging it. “What if something’s gonna hit you in the head? You should listen,” he nodded, thinking about it. “But once you listen, you should decide what you want to do.”
“What if I wanted to...eat you?” Billy asked him, reaching down to tickle Steve’s stomach, and Steve yelped, giggling.
“You won’t eat me,” Steve told him, leaning into Billy, to give him a hug. “You’re nice.”
Billy sighed, and hugged him back, tightly.
Billy was better at some things than other people, like clothes, Steve thought, because Billy was always pointing people’s outfits out, and explaining how they weren’t as good at picking them. He wasn’t as good at other things, though. Steve sat down one night to heated-up pasta sauce over Cheerios, and he didn’t want to say anything, but he was pretty sure that wasn’t right. Billy gave Steve’s mom a glass of water that was completely frozen because she said she wanted it iced, and when Steve’s dad told Billy to make burgers, Billy didn’t buy buns, or tomatoes, or anything, and he threw the meat in the pan until it caught fire.
Steve was pretty sure none of it was a joke, because Billy frowned between the glass and Steve’s mom, and grimaced over the burgers after Steve’s dad stomped away, and Steve caught him whispering into the phone to the neighbor, hiding half in the fridge like nobody was gonna notice it was open.
“Billy,” he whispered, and Billy jumped, as Steve crouched down next to him. The breeze from the inside of the fridge was nice, but it hardened all Steve’s suspicions, because no grown-up had ever left the fridge open, he was pretty sure.
“Yeah,” Billy muttered back, guiltily.
“...how old’re you,” Steve asked, and Billy flinched.
“Older than you,” he shot back, and that Steve was willing to give him, because Billy wasn’t human, and some things lived different amounts of time, like trees.
“Are you a kid too?” Steve asked, and Billy glared at him.
“No,” he said defiantly, and Steve nodded slowly, raising his eyebrows, until Billy groaned, deflating, sitting against the edge of the fridge and letting his legs sprawl out across the floor. “Look, I’m trying—”
“I won’t tell,” Steve said, reaching out and squeezing Billy’s hand. “I don’t want you to get in trouble.”
“...teenager...maybe,” Billy admitted, grimacing.
“Okay,” Steve said, nodding. “Billy,” he said, trying to sound like a parent, or a teacher, and Billy’s shoulders hunched. “You need to tell me you need help,” Steve said, putting his hands on his hips. “I can help with things like human food.”
“You are human food,” Billy said, fondly, yanking Steve into a hug.
Most of the people that did magic like Billy ate kids occasionally, Steve found out, as he was reading his Dictionary of the Magic Realms that night under the covers, by flashlight. Maybe they were mean kids, Steve thought, or maybe Billy was just way nicer. “Are you a fairy?” he asked the next morning, and Billy laughed.
“Depends on what you mean,” he said, grinning over. “Is that slang for—”
“Can you fly,” Steve interrupted, because that seemed the most important, and Billy cocked his head.
“...actually, I probably could,” he said, considering. “Not like you mean, though. I don’t have secret butterfly wings, or anything.”
“Oh,” Steve said, because he'd been privately imagining Billy as they’d first met, with the jewelry and the horns and wings, and it seemed to fit.
“...do you want me to have wings?” Billy asked, sitting aside the dish he was drying, and bending down sideways to try and meet Steve’s eyes. “I can change form—”
“No!” Steve told him, waving his hands. “No, I know you like looking like...that.”
“...that,” Billy said, raising his eyebrows as he looked down at himself. “You saying I need to do better?”
“You’re just—normal,” Steve said quickly. “Instead of pretty.”
“Instead of,” Billy growled.
“I mean,” Steve yelped, waving his hands. “Pretty with all the jewelry! And the horns.”
“I was gonna say,” Billy said, reddening. “If you’re saying I’m not pretty—”
“Of course you’re pretty,” Steve said, rolling his eyes and sighing, but grinning, too. He patted Billy’s shoulder.
“Well,” Billy said, clearing his throat, and turning back to the dishes. “All right, then.”
A few days later, Billy was moving the kettle off the flame for hot chocolate, and a big gout of steam belched up over his arm, which shimmered into all over scales. Steve yelped and grabbed him, yanking him over to the sink, and ran water over it, all the while panicking.
“Billy, are you a mermaid?!” he asked, spraying Billy’s arm, and trying not to cry. “Are you a mermaid, are you okay, are hot things bad for mermaids—”
“I’m okay,” Billy told him, turning off the water, and hugging him close. “I’m not a mermaid, Stevie, I’m not hurt.”
“O-okay,” Steve gasped, grabbing Billy’s arm to run his fingers over it. “You—you’re okay,” he whispered, leaning into Billy’s hugs. “...are you a...lizard? Or a snake?”
“Nope, not exactly,” Billy said, snorting a laugh, and Steve groaned.
