No matter what Billy did, no one ever stood up to him. He was strong, violent, and more than a little crazy, so he was allowed to do whatever he wanted without consequences. You were sick of that. You saw him almost mow down your boyfriend's little brother, Will, just a couple of weeks ago in that stupid car of his.
His prized possession, that goddamn Camaro.
It came to a head when he showed up at Jonathan's place, already pissed off about something.
âAm I dreaming, or is that you, Harrington?â God, what a prick.
You didnât listen to the rest of the conversation. Max looked scared, and that alone made you see red. Sheâd become a little sister figure to you; watching her shrink whenever he came around made something sharp and hot twist in your stomach.
So when Billy charged inside with his wild gaze locked on her, you did the one thing you knew would divert his attention â you nabbed his keys from his back pocket and ran.
If only I knew how to drive stick, you thought with a grimace as you pushed yourself forward. It was a full ten seconds before you heard his boots pounding the grass behind you.
âYouâve got one fucking chance to give them back!â he yelled, gaining ground. The only answer you gave was a middle finger thrown up in his direction. He lunged for your arm, and he mightâve caught it, had you not spun out of the way and kept moving. His frustrated roar motivated you to go faster. Your heart was pounding in your ears and your lungs burned with exertion, but you couldnât stop. Not yet. Not until you were sure you'd bought the kids enough time to put defenses up.
It got quiet â too quiet.
You threw a look over your shoulder and saw Billy walking calmly like he was confident heâd get you sooner or later. That sent a shiver down your spine. The thought of what he might doâ
He disappeared as the ground fell out from under your feet, plunging you down into darkness.
âFuck!â
You landed on your stomach with a dull thud. Pain radiated outward from your core and you struggled to catch your breath. Billyâs keys were still clutched in your fist. For one fleeting moment, you felt a sense of vindictive pride because heâd have to come down and get them, wherever this was.
It was dark, but a strange blue glow emanating from the walls gave off just enough light to see by. Something writhed under you; they looked like vines, but they were wrong. Disgust and panic flooded your system. When you tried to scramble away, they wrapped themselves around your legs and dragged you back to where you started. Kicking did nothing; you were trappedâŚand heavy footsteps were approaching the hole you fell into.
This cannot fucking be happening. What do I do?
You looked around for something to fight Billy off with. By some stroke of luck, there was a pocketknife stuck in a bulbous, flower-like thing on the wall. You reached for it. Your fingers closed around the handle when the grotesque plant opened and spit something into your face. It hit you like confetti blasted out of a cannon. Worse, it was warm, clinging, and sticky. You yelped and threw your arms over your eyes, but it was too late. It coated your lips and slid into your mouth. You swallowed on instinct and instantly regretted it.
Billy dropped into the hole to find you gagging, coughing, and hopelessly stuck.
âWell, well.â The bastard was so smug about it all. You wanted to hit him. He rounded your body and crouched down. âYouâre kind of a dumb bitch, you know that?â The insult hit like a punch to the gut.
It wasnât devastating or clever. It wasnât even particularly vicious â just Billyâs normal brand of sexism. It stunned you for a different reason.
Heat pooled low in your stomach, and you became all too aware of the fact that your skirt was hiked up high on your thighs from the struggle against the vines. Your nerve endings lit up like a goddamn Christmas tree. Every sound was sharper, every breath heavier, every inch of your skin hypersensitive.
No. This definitely isnât happening. Iâm in a nightmare, because there is no way Iâm turned on by this piece of shit.
But the evidence didnât lie.
He smelled like smoke and some vaguely spicy, floral aftershave. Youâd never noticed how pleasant it was because youâd been busy keeping your distance. He was leaning in; it gave you a perfect view down his barely-buttoned shirt to his toned, tan skin. Billy smirked and grabbed your face with one calloused hand. He pinched your jaw between his fingers and forced your gaze back up.
âWhat did you think would happen when I caught up to you, huh?â He scoffed. âDid you even have a plan?â You glared up at him and refused to answer. He squeezed your jaw tighter. âI fucking asked you a question. Answer it.â
You took a deep breath to tell him to fuck off when that horrible alien plant sprayed more of that white fluff into the air. This time, it got him, too. Both of you coughed and wheezed. He jumped back out of reflex but the damage was already done.
âWhat the fuck was that?â
He stared down at your prone body, brow furrowed like he expected you to know. You couldnât answer; the only sound that slipped past your lips was a frustrated whimper you immediately tried to disguise as a cough. He wasnât stupid, though, and his expression changed the second you made that pathetic little sound. His pupils dilated. Any trace of smugness left his features, and all that was left was a predatory stare that made your stomach flutter.
Those spores were bad enough the first time around. Being double-dosed made existing near him damn near unbearable. Just looking at him, feeling the heat of his body gave you a visceral reaction that made you fucking furious. The last thing you wanted was to touch this jerk. Heâd done nothing but bully everyone you loved, for fucks sake! You squirmed against the hold of the vines again, but it was no use. They only wound higher and tighterâŚand you had a mounting problem.
Your nipples were hard and sensitive and every brush of drafty air in the tunnel gave you goosebumps. A persistent pulse between your thighs ached. You were dripping like a fucking faucet, soaking through your thin cotton panties.
âGod, help me out of here!â you growled at him, clenching your fists. âIâll give you the keys, justâŚhelp me. Please.â You refused to look at him. It would only make your current situation worse. Besides, the blow to your ego at having to be polite to him made your cheeks burn with shame.
He didnât move.
âThe hell is happening to me? What did you do?â Billy demanded. Your eyes roved up to his waist. He was so hard in those tight fucking jeans you could see the outline of his cock straining against the denim in clear detail.
âMe? I didnât do anything, you perv!â You covered your eyes and made a desperate attempt to close your legs. The vines wound tighter, keeping them spread. Your skirt slid higher and hiked over the curve of your ass. âStupidâfuckingâugh!â you screamed in frustration, struggling harder. By the time you stopped fighting it, the fabric was bunched over your waist. âDonât just stand there! Help me, you asshole!â
The vines shifted again and pulled your legs further apart, spreading your pussy open with a slick, wet sound.
Billy shuddered and inhaled deeply.
âGross! What are youââ you protested. The words died on your lips when he took a step forward. Your heart skipped a beat. âBillyâŚâ
He wasnât listening. You watched his legs as they moved to circle behind you. Your back arched and your thighs shook; you felt like a marionette, every movement orchestrated by your body without the permission of your mind.
Every logical part of your brain was screaming.
You donât want him! You donât want this, you hate him! Remember Jonathan, your boyfriend? Your loyal, devoted boyfriend? You love him, youâre going to tell him that as soon as this shit is over!
It didnât matter. All the logic in the world couldnât stop you from clenching around nothing. It wouldnât make your body stop offering itself up on a silver platter to the guy everyone in your life hated. Those spores, pollen â whatever it was â had wrested the controls from you.
It was a unique kind of torture, and it was getting harder by the second to resist. You were entirely at the mercy of a man who was volatile even when he wasnât being possessed by an alien flower, and you were both fighting a losing battle.
You flinched when you felt his rough palms slide up your legs. âBilly, pleaseâŚâ
âIâm fucking trying,â he said through gritted teeth. âYou just smell so fucking good, Iâfuck, I canâtâŚâ
His hands moved higher and you shivered. A wave of slick gushed out, hot and humiliating. Every touch stoked a fire you couldnât put out. His fingers stilled on your thighs and dug in hard. The breath punched from his lungs in a sharp huff and you felt it through the fabric of your underwear. It only made you needier. Your hips writhed in response and he groaned, palming your ass, kneading the soft flesh.
âIâI have a boyfriend,â you stammered weakly. âListen to me, itâs the plant. Itâs the stupid fucking plant andââ His thumb traced down your inner thigh and brushed over your clit through those stupid pink panties. âOhhh fuck.â You hissed through your teeth and a desperate whine escaped, giving away too much.
Billy stilled. For one charged moment, neither of you dared to breathe.
"No, fuck this," he spat. His voice was strained. "Give me my keys."
He was just pulling away when another one of those disgusting growths opened in the darkness and expelled more of its nastiness right by his head. His muscles locked up and his breathing grew ragged.
â...Billy?â
The vines pushed upward, lifting your hips and leaving you exposed and helpless. They were presenting you to your worst enemy; somehow, the notion made you wetter. It was obscene. It wasn't natural. Then again, nothing about the situation was normal or natural. When tendrils hooked under the waistband of your panties and pulled, you shuddered. The chilly fall air hit your clit and you writhed. It was already too much. Billy still hadn't said a word, but the clank of a belt buckle and a zipper coming down was answer enough. You felt the heat of him before he even touched you, and your hips jerked back greedily. The vines still held tight. You made one last futile attempt to remind yourself that this was wrong, but every single thought was replaced by visions of being bred mercilessly.
Billy was all too ready to oblige.
He shoved in unceremoniously and groaned so loud it echoed off the tunnel walls.
"God â fuck, if I'd have known you were hiding this perfect cunt from me, I'd have taken you sooner," he growled, gripping your hips for leverage as he pounded into you. You felt bruises blooming where his fingers dug into your skin hard. "Wasting it on Byers. Goddamn tragic." The sting of him stretching you was nothing compared to how good it felt to be so full, and you wailed as he dragged you back to meet him thrust for thrust.
"Yeah? Feels that good, huh?" You knew if he was himself, you'd be able to hear that infuriating smirk in his voice, but it was more like he was on a mission, taunting you through gritted teeth. You realized with detached horror that he was on a mission. The heat, the visions, the aid of the vines â oh god, it was trying to get you knocked up. And worse, it made you want it.
You clenched around him as the revelation hit you and he grabbed a fistful of your hair, yanking your head back to look at your face. You wanted to scowl at him for following you down here. He knew it, too. He also knew you wouldn't; he let go of your hair only to wrap a hand around your throat and pull you up against him. The change in position made your legs shake â or, it would if the vines weren't holding you still and steady. You couldn't stop him or yourself; you'd resigned yourself to that. But this positionâŚit was too intimate, and it felt like heaven.
"Don'tâ" you pled.
"Shut up."
Another rough thrust choked off the retort you tried to form. Billy nipped and sucked at your shoulder, your neck, your earlobe. Anywhere he could reach, he left marks you wouldn't be able to hide easily. Your traitorous fucking hands moved of their own accord: one braced against his muscular thigh while the other snaked down your body to rub tight circles over your clit. He slapped that one away to do it himself. The pleasure was blinding and your hips bucked into his touch and high pitched, pathetic screams ripped from your lungs.
"Fuck! Oh god, please, don't stop!" The words just slipped out; to your own horror, you meant them.
His low, wicked laugh right next to your ear gave you goosebumps and you felt yourself hurtling toward the edge. Clearly he was enjoying everything this cost you. Of course â he was stuck in the same situation but still somehow found satisfaction in your helplessness. Classic Hargrove.
"How's Byers gonna feel, watching you carry my kid?" he grit out. The thought should've disgusted you. It would have, half an hour ago. Now all it did was make you flutter around him. Your body was urging him on even if you wouldn't reply. "That's what I thought. Now be a good slut and cum for me."
You didn't have a choice. The tension inside you snapped and your body shook as you came, sobbing with ecstasy. Your walls pulsed so hard you pulled an honest-to-god moan out of him. He pushed you back down into the dirt and planted his hand between your shoulder blades to keep you there while he rutted into youâŚas if you had any say in what was happening.
"Goddamnâthat's it, take it," he panted. You felt his cock twitch and he buried himself to the hilt as he spilled into you with a ragged groan.
It felt like forever before either of you so much as moved. You were too busy trying to catch your breath and absorb what you'd done. Then it all seemed to hit both of you at once.
"Jesus Christ."
"Oh my God."
The vines receded. Billy pulled out and you rolled onto your side, covering your face with your hands. Your eyes burned; you didn't want to cry in front of him, but the sudden crushing guilt you felt left no room for restraint. The tunnel was silent except for the sound of your sniffles and pathetic whimpers. His voice was rough when he finally spoke.
"IâŚdon't know what that was about," he murmured. "But I'mâI'm sorry. I don't, I mean I can'tâI couldn't control myself. Fuck."
"S'not your fault," you replied in a small voice. "Neither of us could help it." You flipped to your back and lifted your hips to pull your underwear back on. Your mind was already racing, trying to find ways to explain what happened without breaking Jonathan's heart. When Billy offered you his hand to help you up after, you hesitated but took it anyway.
Just as your hands touched, that almost painful need slammed back into you. You pulled him down with surprising strength and wrapped your legs around his waist.
As he ripped your panties clean off of your body, you knew: the night wasn't over.
Not even close.
