A/N: this smut got out of hand. Fair warning, gang! This is p filthy for


"Hey, sorry it took so long," Caoimhe said, sneaking up behind Eddie.

"You're always exactly on time. It's fucking annoying," Eddie replied, turning around to face her.

Caoimhe straightened up and glared, daring him to say something about her outfit. In a moment of weakness, she'd chosen to wear the matching skull necklace. They'd laughed at all the couples in matching costumes when they went to Halloween parties. But Eddie looked stunned like she'd caught him with his hand down his pants. That was a thing about Eddie Munson- every emotion he felt was shown on his face in real-time. He flipped through them so fast that it could make a person dizzy. But Caoimhe had been watching him for years, and nothing about him made her dizzy. There was no fear; she realized the longer they looked at each other. No thoughts about the future because Caoimhe couldn't get over herself. Eddie fit into her life. He had for years.

Eddie was like- ah, how to explain it? He was like sleeping on the magic bus with her brothers curled around her or laughing with Chrissy as Caoimhe taught her how to dye yarn with beet juice. He was like auditioning for a role- standing on a stage that felt like home as soon as she opened her mouth to sing. He was like listening to the Clash for the first time and realizing that maybe she didn't have to be Nikki. She could be Caoimhe. She could wear Docs and be a vegetarian. Pierce her tongue and read Kerouac. She could lie on the grass with Eddie's coat cushioning her head as she waited for him to finish a drug deal and then make him listen to Black Flag on repeat until he demanded she shut it off. Her parents didn't tell her who she was or anyone else. She made herself.

"You were the first person in Hawkins who called me Caoimhe," she finally said.

Eddie smiled. That sly little tilt to his mouth, going all the way up to his eyes that looked dark underneath the dingy kitchen lights. The smile she saw in her dreams. That smile, she realized with a strange giddy feeling in her chest, had never been for anyone else.

("I don't want to date Eddie. Actually, I never have, and he hasn't either."

"How do you know?"

"Because of the way Jason looks at me. Eddie has never looked at me like that. But do you know who he has looked at like that?")

And Caoimhe, obstinate as the day was long, had a goddamn epiphany. About time, too.

"You didn't look like a "Nikki" to me," Eddie said.

"You've never liked Chrissy, have you?"

He could have teased; Caoimhe could tell he wanted to. But he shook his head, shrugging and acting, "you got me."

"You never wear your glasses, and you're blind as shit, Kee," Eddie said. "I've never looked at Chrissy. I've never looked at anybody, actually. Just you. Since."

"Since when?" she pressed.

"The summer of '76." He shrugged again like it didn't matter that he was baring his entire heart for her of all people. "You were coming out of the library with Chrissy. I'd just been passing by riding my bike back from wherever and saw you lookin' mad as hell, arms crossed over your chest and glaring at your reflection in a car window. Felt like I got sucker-punched; you were that fucking pretty. You caught me staring and flipped me off. Turned your nose up and ran away in these ugly sandals. They looked homemade."

"But, wait, hold on, that was before."

"I never thought I'd see you again. I was supposed to go back, but my dad went to jail, so I moved in with Wayne."

Eddie cupped her face in his hands, and she leaned into his touch. His rings were cold on her skin, but she felt like she was burning up. How could she not have realized how he looked at her? Maybe she did need to wear her glasses.

"That spring, you were my science tutor," he continued. "I had a buzz-cut, and you beat a kid up for Eamon. Your nose was bleeding, and you looked right at me and smiled this terrifying smile. Thought you were pretty before, but after that? I was done. I told myself I was happy just being your friend, but I was so wrong."

"Really?"

"Hand to Ozzy, sweetheart. The Munson doctrine decrees that I never lie. Not to you."

Caoimhe smiled and kissed the pad of his thumb. He was brave, even if he didn't think he was. She could be brave, too. Take a chance. Bear her soul. It was only Eddie, after all.

"My family had to leave Donegal -Ireland, you know- before everything, but they made a home in the south all the same. I never saw two people as in love as my aunt and uncle. They were always touching, even if it was just hooking their pinkies together. They'd smile at each other like they knew something everyone else didn't and watch when the other wasn't looking. Sing together and dance in the living room. Make fun of each other, but it was never mean. They reminded me of us," she said. Then: "I'm sorry it took me so long."

"It's okay. You got there eventually," Eddie said, fiddling with his hair and pulling a strand over his mouth to hide his smile.

"Look at you, Eds. You're smug as shit right now, aren't you?"

"Are you kidding? Why the hell wouldn't I be after that? And you called me sexy."

"You are sexy," she said, leaning up to bite his chin.

"Aha, nope. I will not be distracted. I have a plan. Our ice cream's ruined. Now, go, shoo, to the car."

Eddie wrapped his arms around Caoimhe's waist even as he nudged her to start walking. They made their way to his van like that- slowly and knocking into each other, but she wouldn't ask him to stop for anything. Paul Simonon from the Clash could walk into her house and ask her to marry him, and Caoimhe would tell him to fuck off the nearest bridge.

"What's up your sleeve?" she asked.

"You, me, a picnic in the woods." Eddie moved some of her hair out of the way to kiss a trail up her neck. "I brought my guitar."

"Yeah?" Caoimhe tilted her head to give him more room. "Are you going to serenade me, baby?"

"Nope. You're going to serenade me. But not if we don't -fuck, Kee, you like that? Right there? Okay, okay, sweetheart, yeah. I got you.- shit, not if we don't get out of here soon. Jesus, you're so distracting."

Caoimhe bit back another moan and pressed herself against Eddie's chest. He held her tighter, nipping at a spot behind her ear that made her crazy.

"You started it," she accused.

"I'm a ruffian, babe." Eddie was grinning; she could feel it when he bit her. "A- what did you call Kieran?"

"Hellion."

"Yep, that's me. A thief going rogue for his princess-turned-assassin. I'd get down on one knee and pledge my fealty to you, but I kinda want to keep kissing you."

"You can always do it later," she said.

"Mhm," Eddie said. "Christ, we gotta go. I have plans."

"Then let go of me."

"Just one sec. One more. Shit, I knew I should have jerked off before I came to pick you up. C-can't take it. You're wearin' my ring around your neck."

"It's not exact. Ow, Eds!"

"Sorry, sorry, sorry, sorry," Eddie mumbled, pressing soft kisses to the spot where he bit too hard. "I'm sorry, sweetheart. Got no self-control when it comes to you. Let me just- one more."

It was not, in fact, only one more. Caoimhe reached behind herself to curl a hand around Eddie's head. He muffled a moan when she pressed his face into her neck, and she closed her eyes. Heartbeat pounding away in her chest, then plunging between her legs when he drove his hips up. Her hands clenched into fists, trying to hold herself back. Racing thoughts because she wanted to flip them around and push him up against the van. She'd seen the handcuffs in his room. She wondered if he'd let her use 'em on him.

"Eddie," she moaned in the way she knew he liked.

She hadn't realized it until he had her on his couch, coming with his fingers shoved up inside her. She'd moaned, and he'd stuttered in his movements and looked like she'd knocked him for six. Then when she got home, half delirious and half aroused, memories came to her unbidden. She'd moan Eddie's name when he pissed her off or when he was refusing to study or when he made fun of her music. Whenever. She thought it was an exasperated moan, at least to her it was, but Eddie'd turn docile as soon as she did it. She'd pop out a quick moan of his name, sometimes drawing out the last syllable, and he'd shut his trap and do whatever she wanted with pink cheeks.

"Y-yeah, baby?" he stammered, smudging his face into her shoulder.

Oh, she made him nervous, how sweet.

"Take me to the bus."

"But I had plans," he whined. "Wanted to do this right, you know? Go on a date an' kiss you in the woods; not your backyard."

"Eds," Caoimhe moaned.

Her ace in the hole. She wondered when he'd finally realize.

"Okay, okay, okay, yeah, to the bus. I'll take you to the bus."

It was slow going again as Eddie seemed loath to detach himself from her for even a second. Like a pretty barnacle with calluses on his fingers that scraped against her cheek when he nudged her head to the side so they could kiss. She turned in his arms, and he backed her up until she was trapped between the bus and him. This time, her moan was real. She threw her arms around Eddie's neck and kissed him, sucking his bottom lip into her mouth like she knew he liked it. She was learning so much about him. He braced one hand on the bus and curled the other around her neck. His fingers pressed down. Caoimhe's cheeks burned.

"Eds," she began, but he silenced her with a smirk on his stupid face.

"Get on the bus, Princess Caoimhe."

"You get on the fucking bus," she muttered, stomping up the stairs.

She shrieked when Eddie picked her up and tossed her onto the sofa like it was nothing. He'd been a shrimp before, Caoimhe thought. He must have gained muscle tone lugging his big head around all the time.

"I've always liked this bus," Eddie remarked.

"It's like a massive middle finger in the middle of Hawkins, right?" Caoimhe replied.

"I mean, yeah, that too. But it reminds me of you."

He pulled his shirt off. She ogled. It was okay; she could do that now. He was lean, save for the etchings of a few ab muscles doing their best to draw her eye and wonder when the fuck he'd gotten them. His trailer park tattoos, too; Caoimhe had seen them before. She'd cleaned every one of them because she didn't want Eddie to die of septic shock or hepatitis C and knew he wouldn't clean them right. He'd let her but couldn't meet her eyes for a few days afterward. Now she knew why. Eddie crawled on top of her and pushed her dress above her stomach.

"Looking pretty red over here, sweetheart," he crooned, rubbing circles into her hips.

"Bite me."

"I did. Multiple times. D'you want me to do it again?"

Jesus, she was trying. She wanted to tease and flip them over so she was on top, but she couldn't fucking move. She could only be honest.

"Yeah, Eds, please."

She sounded a little too much like she was begging already, exposed like a live wire, but if she trusted anybody to see her like this, it was Eddie. Eddie, who saw how hard she was trying, dropped the smirk off his face. He smiled that smile that was hers, his pretty brown eyes going soft.

"I got you, Kee. Okay? Won't let anything happen."

She nodded. He leaned down to kiss her, smiling when she nibbled on his lip because she couldn't help it. She was a nervous thumb sucker until way too late and read Freud and his bullshit theories when she was fifteen. But maybe she did have an oral fixation. At least, when it came to Eddie because she had half a mind to latch her teeth around his forearm and never let go. What was her deal?

"Y'can bite me," he mumbled like he'd been hearing her fucking thoughts. "I don't mind. I like it."

"You do?"

"Yeah. Listen, I mean, you bite when you fight people. And I like it when you fight people, so it's a natural progression to me liking the idea of you biting me. I kinda, heh." Eddie trailed off and pulled away.

"What?" Caoimhe asked, furrowing her eyebrows.

"You know how edibles make me horny?"

"Yeah, you weirdo. That's so weird, Eds. They make me feel like I'm melting."

"Shut up. Your experience isn't universal. Anyway, it's pretty shitty when we do 'em together because you leave, and I'm left with this awful boner and thinking about you the entire time. You, in any way I can get you, but you're always biting me, so."

"You're a fucking freak," she replied, smiling.

"So are you, you goddamn vampire!" Eddie said indignantly.

"Mhm." She tucked a finger into his necklace. "Just call me Lucy Westenra."

"Screw you; don't bring up school. You know I have to read that stupid book for English class."

Caoimhe agreed, kissing him once.

"I'm sorry, baby. You're right."

"Thank you. Now-" And here, Eddie's expression turned sly. "-I seem to remember you blowing me the last time we hung out. Great job, by the way. Think I went blind. In fact-"

"Is there a point to this?" she interrupted.

"Well, yeah, let me return the favor. I'm a gentleman, after all."

"I thought you were a hellion, Eds."

"I can be both. What do you say?"

"Like you even need to ask."

His smile was huge. "I was hoping you'd say that. Thanks for wearing a dress, by the way."

"You like it?" Caoimhe asked, feeling shy and hating herself for it.

"Jesus, yeah, you kidding me?" Eddie grinned boyishly. "You got legs, Kee."

"Thanks."

"Any time. Now, if you don't mind, I'm just gonna shimmy like this and stay right here, and then just lift you right here over me."

He swallowed, looking a little frazzled. She wrapped her arms around his neck.

"On top, huh?" she asked.

"Yeah, yep, I think so. Arms up."

Caoimhe did so that he could pull her dress off. It was one of those sweater dresses, making her hair stand on end from the static electricity. It wasn't fair; Eddie still had his pants on, but she'd let it go just this once. He threw her dress near his shirt and spread his hands around her waist. Let her kiss him and dug his fingers into her skin when she caught his tongue between her teeth. He still had a couple of hickies from the last time, Caoimhe noted with pride simmering in her chest. They were faded but still there. She ran her thumb over one as he mouthed at her throat. Eddie reached behind her and unclasped her bra. His rings were still cold as shit, and she hissed through her teeth as he plucked at a nipple. He really liked her piercings if his muttering was anything to go by. Eddie was a talker. So was she.

"You should get yours done," she said, pulling the hair tie from his hair.

"Think I could pull it off?"

"If you go to a professional and not someone in your trailer park."

Eddie's voice was muffled now as he had one of her nipples in his mouth.

"You got yours done professionally?"

"Y-yeah," she stuttered, arching her back.

She knew this wasn't his first rodeo because they'd talked about their sex lives at length, but hell, the bastard knew what he was doing. She would have figured it out anyway. Sloppy with spit, like he was marking her as payback for all the lipstick she'd smeared on him the last time they did this.

"Hm, how bourgeois of you," Eddie said.

"Dude reads the Communist Manifesto once and thinks he knows everything," Caoimhe moaned.

"It's not very punk of you, is all I'm saying." Eddie switched sides. "Christ, you got nice tits, sweetheart."

"I didn't want to do it myself and bleed like a stuck pig -Eds, fuck, baby-"

"You like this, huh?"

When Caoimhe nodded, he nodded back, grinning.

"Yeah, I bet you do. Don't think I don't see that blush going all the way down."

Eddie bit down on her nipple and tugged the ring between his teeth until she nearly smacked him in her haste to leap away. She mumbled something about being too sensitive, but he ignored her and tugged again. Caoimhe slammed her hips down in revenge. Oh, he was hard. His eyes looked glassy as he watched her, grinding now because his jeans were catching on her clit just right.

"Fu-uck," he stuttered, driving his hips up to meet hers. "Jesus Christ, Caoimhe."

"Eddie, please, please."

"Yeah, yeah, what? What can I do?"

She was half out of her mind, and hardly anything had happened. Was it always going to be like this? Intense as anything, but also like this was where she was supposed to be, with Eddie, and the universe was thrilled about it? He was so stupidly beautiful, and Caoimhe was an idiot for not realizing sooner.

"Rings," Caoimhe said, which wasn't an answer.

"Okay, all right, yeah," Eddie agreed because apparently, he knew what she meant, bless him.

He sounded eight shades of pleased with himself, and Caoimhe promised herself he'd get him back later, but his hand was between her legs, and she had other, more pressing matters to deal with first. Eddie swiped a finger over her clit. She almost keeled over.

"Open your eyes for me, Kee," he cooed.

Caoimhe did, glaring.

"I hate you," she muttered.

"Yeah, I know you do." Eddie smiled widely. "Get yourself off, and then I'll fuck you. Bet I can give it to you twice."

"Smug bastard," she snarled but did as he'd asked.

Was this why he wore such giant rings? That stupid pig one she'd initially gotten as a joke quickly became her favorite as it nudged right up against all the right places once she picked up her pace. It was sweltering, burning up; hell, what if someone came in again? Goddamn it, they needed to stop doing this shit in places where they could get caught. Why the hell hadn't they done this sooner? She hadn't even completely seen his dick yet and already knew she was screwed.

Eddie was mumbling under his breath. Caoimhe peeked open one eye.

"Wassa matter?" she slurred.

"Nothing. You're just sexy as shit, and I got a killer boner right now."

"Sorry."

"For what? Giving me a boner? You always somehow manage to. I was a mess around you in middle school; didn't you notice? You'd glare at me for not doing my homework, and it'd happen."

"Shaddup, you're ruinin' it. Be nice," she said.

"I'm always nice. Think I like you like this. You gonna come?"

"Will if you keep being nice to me."

"Wha-oh." Eddie looked like he had a revelation of his own. "You like it when I talk, don't you?"

"Yeah."

"Christ, shit, yep, okay, o-kay, one, you're easily the hottest thing that's ever happened to me, bar none. I think about you all the time. Think about fucking you all the goddamn- ah, shit, okay, good one, yeah? You gonna let me fuck you, sweetheart?"

"Yes, please," Caoimhe moaned.

"Don't need to say please, Kee. I'll do whatever you want me to. Yeah, baby, yeah, keep looking at me like that. You're so pretty. Jesus. I look at those Heavy Metal magazines and see your goddamn face all the time. Now, I know what you look like all over; it's gonna be even better. I'm out of my fucking mind for you."

Caoimhe threaded her hands into his hair and caught one of his rings just right. He ground out her name, his voice sounding wrecked. She cried out his name, feeling her muscles seize as she tipped over the edge, slamming her lips down on Eddie's to muffle her sounds in case anyone heard her the first time. Going so taut, Eddie had to hold on to stop her from tipping backward. Vision darkening. Crashing waves in her ears. Back arching. The whole fucking nine yards. She was so screwed with this one.

Caoimhe returned to herself more slowly than she would have liked, but it didn't matter much when it was Eddie. Eddie, who was kissing her flushed cheeks and holding her tight.

"So hot; Jesus Christ. Y'look so good when you come. Really wanna fuck you," she heard him muttering.

"Give me a sec," she said, struggling to open her eyes, "You got me fucked up, Eds."

"Yeah?" He didn't sound as smug this time but happy as a clam.

"Yeah."

"Good, I like you fucked up. You're beautiful. You still hate me?"

"Kinda."

"Oh, you little liar. Give me my hand back. Why are my rings all wet if you hate me so much?"

"Haven't you heard of hate sex?" Caoimhe teased.

"Come on. You don't kiss me like you hate me," Eddie replied, smiling her smile.

"Fine, you got me. I could never hate you."

"Ha, I knew it! You okay?"

"Yeah, all good." She rolled her hips, and Eddie shuddered. "Take it out; I wanna see. Bet it's as pretty as I've always wondered."

"You've wondered? Heh, yeah, okay. S-stop rolling your hips like that."

She bared her teeth and bit the tip of his nose until he pushed her off his lap. Caoimhe landed on the floor with a snort of laughter.

"Take 'em off, baby," she coaxed, pushing her underwear down and kicking them off.

Eddie stood up.

"Yeah?" he asked, grinning. "You wanna see?"

"Shut up. Stop preening over there and do it."

He did, albeit very slowly. It took her a few beats too long to realize he was teasing her, the bastard. Caoimhe threw a pillow at him. Eddie yelped, all dramatic like always, huffed and shoved everything down his legs. Caoimhhe had always been indifferent to the look of a dick. She liked boys, and boys had them. They were okay, sure whatever, nothing special. Eddie's. Hm. She stared a little. Eddie's dick was as pretty as he was. She was right. Her face must have been red again because Eddie smiled like the cat who got the canary. He leaped at her, rolling them around until he had her flat on her back.

"Well?" he asked, holding her arms down and kissing her with too much tongue.

"Decent."

"Just decent? You sure?" Eddie let go of her wrists only to wrap his hand around her throat. "You're blushing pretty hard over there."

Caoimhe moaned, frustrated. "Eddie."

"Hm?" he hummed.

He was thrusting his hips mindlessly like he wasn't thinking about it but grinned when his dick caught on her clit, and she went a little cross-eyed. Jesus, he was such an asshole. She wiggled underneath him, shaking so hard that it hurt when he gripped her neck tighter to keep her still. Everything was burning. A goddamn forest fire and it was barely March. Caoimhe took a ragged breath.

"Eds, please, please," she whispered.

"You're so impatient, sweetheart," he replied, leaning down to kiss her.

She pushed his face away. "Fuck you; how many times do I have to say please? I hate being teased. You're so mean."

"All I ever am is nice to you," Eddie said, shaking his head.

She was about to respond, mouth open and fire in her eyes, but he must have been waiting for that precise thing to happen because he pushed inside, inching his dick in slowly like he was trying to be coy, but Caoimhe could see he was struggling too. She wanted to start yelling about it, but her mouth wasn't working much. Static in her brain as Eddie pulled out and slammed back in, still holding onto her neck. Not pressing enough to hurt, just holding her. He pressed his face to hers, sounding ragged as he panted hot air against her cheek.

"Christ, s'fucking good. So fucking good," he babbled, sounding wrecked.

Caoimhe grabbed his hair and held on tight as he sped up. Rough as hell. Holy shit. His teeth were in her neck again, scraping over reddened skin. She adjusted her thighs around his hips and cried out, eyes slamming shut, abdominal muscles quivering. Eddie cursed a blue streak when she spasmed around his stupidly nice dick that was currently making her go insane.

"Right there, Eds, please. Feels amazing."

Eddie wrapped his arms around her and held her tight to his chest.

"Yeah, I got you; hang on." He gulped. "Christ."

Nope, she'd called it before. She was ruined for good. There would be no one else like Eddie, not that she would admit it to him yet. Is this what love felt like? When he found her clit and started rubbing it for her because she was too busy digging her nails into his skin to do it herself? When he shifted them slightly, he was hitting that spot inside her that made her wail, her mouth dropped open, and she gasped his name. When he pressed his sweaty face against her cheek and panted her name in her ear like it was the only thing he wanted to say for the rest of his life. Caoimhe pricked her nails into his neck, her back arching. Eddie's hips stuttered, swearing under his breath as she tightened around his dick. Stupid, stupid, stupid boy, oh, she despised him. She wailed Eddie's name like she was auditioning for goddamn Carmen. Like a fucking alley cat, scrabbling for his face to kiss him because she was being too loud and her brothers were home. Her eyelids slammed shut as colors burst behind her eyelids.

Caoimhe kicked her leg out, and it hit something hard, making her yowl in pain and twist away, but Eddie held her tight, pushing himself deep inside before coming with a broken moan of his own. Like sweet music to her ears. She laid there feeling like she'd done something extraordinary. She started to laugh. Eddie pawed at her breast like he was trying to find the off switch.

"What?" he asked, all grumpy like she was making fun of him.

"No, nothing, I just- we're idiots. We could have been doing this for years."

"Oh," Eddie said with a grin. "Yeah, we're morons. If I had known how good your pussy was in high school, I would have done my damndest to pass the first time."

"I'm happy to be your motivation whenever you need it. I'm unselfish like that," she said. "So as long as you always fuck me like that, anyway."

"We'll have to do it again, of course, to see if this first time was just a fluke," Eddie mused.

"Obviously. For research purposes," Caoimhe said reasonably.
