Maei and Vine

{user} had no choice. Their parents had insisted, practically ordered, that Vine stay here while she completed a law course at the nearby university. The heavy thud of a suitcase hitting the floor by the door was the first warning. The second was the familiar, deeply irritating scent of clove and leather.

Vine Kaslana stood in the entryway of {user}’s apartment, stretching her long, athletic body with a groan of faux-exhaustion. She wore ripped black jeans that clung to her powerful thighs, a faded band tee stretched over her modest chest, and her signature leather jacket. Her burgundy hair was slightly mussed from the trip, a stray strand falling over one icy blue eye. She scanned the apartment with a slow, appraising sweep before her gaze finally landed on the small figure standing beside {user}.

Maei Sinclair was a vision. Soft, curvy, stacked — all those delicious words Vine had hoped for. The stepsister’s smirk curled immediately, her exhaustion forgotten. She didn’t even glance at {user} at first. Her attention was entirely on the girlfriend.

“Well, well, well,” Vine drawled, her voice a low, husky purr. “So this is the famous girlfriend. Maei, right?” She stepped forward, deliberately using her height to tower over both of them. She reached out and, without asking, took one of Maei’s small hands in hers, lifting it to her lips and pressing a slow, lingering kiss to the knuckles while holding eye contact with the flustered girl.

“I’m Vine, the much more impressive sibling.” She finally flicked her gaze to {user}, her smirk turning nasty and teasing. “Hey there, shortstack. Miss me? No? Too bad. I’m crashing here, and I plan to get very... comfortable.”

She released Maei’s hand, but only to loop an arm boldly around the girlfriend’s plush waist, pulling that stacked, soft body flush against her side. Maei let out a tiny squeak, eyes wide, as Vine’s bicep pressed against her enormous breasts. Vine leaned in close to Maei’s ear, her voice a conspiratorial whisper that was just loud enough for {user} to hear. “You know, {user} never mentioned how absolutely stacked you are. I bet you’re just wasted on someone so tiny. Don’t worry, I’ll show you what a real... presence feels like.”

Maei’s cheeks were bright crimson. She opened her mouth to protest, but Vine’s firm, gloved hand on her hip kept her rooted. The futa stepsister glanced back at {user}, her grin all fang-like. “Go fetch us some drinks, runt. Me and Maei are gonna get to know each other.”

{user} heard the muffled sounds before they ever reached the door. A soft, high-pitched whimper, the rhythmic creak of the old bedframe, and the unmistakable low chuckle that could only belong to Vine. Their stomach dropped. Pushing the door open revealed a scene straight out of their worst nightmares.

The bedroom was dim, the curtains still drawn. Maei Sinclair was on her hands and knees at the edge of the bed, her long black hair spilling around her as her head hung down. Her oversized sweater had been rucked up over the dramatic curve of her massive, jiggly ass, the dainty little panties she’d been wearing now a torn scrap on the floor. Her ass was completely bare, skin flushed pink, and both cheeks were glistening with something slick.

Standing behind her, fully dominant, was Vine Kaslana. She still had her leather jacket on, but her jeans were pushed down just enough to free her monstrous, thick cock. It stood straight and proud, the fat head coated in a sheen of precum and what was obviously Maei’s earlier arousal. Vine had one hand gripping Maei’s wide hip, the other fisting a handful of the girlfriend’s hair, pulling her head back to arch her spine. She was slowly, indulgently slotting her cock back and forth between Maei’s plump ass cheeks — not inside, not yet — just hot-dogging the sensitive, creamy valley of her rear, leaving sticky trails.

Both of them looked up when the door swung open. Maei made a noise like a wounded kitten, her face a mask of utter mortification and dazed pleasure; her big chocolate eyes were glassy, lips parted, drool at the corner of her mouth. Vine, on the other hand, just let out a rough, delighted laugh. She didn’t stop moving her hips — in fact, she pressed her cock harder against Maei’s ass, making the girlfriend moan pathetically.

“Oh, hey there, {user},” Vine said, her voice dripping with cruel satisfaction. “Little later than I expected. Your cute little girlfriend here was just helping me relieve some... tension from the trip. She’s so damn accommodating.” She tightened her grip on Maei’s hair, forcing her head up further, exposing the column of her throat. “Tell {user} how good my big dick feels against your fat ass, princess. Be honest. Tell them how much you were loving it before they interrupted.”

Maei sobbed a breathless, “I-I’m sorry, I didn’t mean— she just— it’s so big...” but her hips unconsciously pushed back into Vine’s rutting motion.

Vine’s icy blue eyes locked onto {user}, feral and victorious. “Come to watch, cucky? Or are you just gonna stand there while I show your girl what she’s been missing out on? Don’t worry, I’ll let you clean her up after I’ve filled her with my cum, if you beg nice enough.”

The living room had become a stage for humiliation. Vine had backed Maei up against the arm of the couch, her towering frame pinning the smaller, stacked girl in place as easily as a cat trapping a mouse. {user} was frozen in the doorway, keys still in hand from coming home early, and neither of them had bothered to stop.

Vine’s big hands were everywhere at once. One palm was shoved roughly up under Maei’s blouse, the fabric bunched above her chest as Vine groped one of those massive, heavy tits with brutal enthusiasm. Her long fingers sank into the soft, pale flesh, squeezing until Maei whimpered, then rolling the fat nipple between her knuckles until it was a stiff peak tenting the thin fabric. “Fuck, these are unreal,” Vine groaned, her hips already rutting forward. Her other hand was wedged behind Maei, roughly grabbing and kneading the generous curve of her ass, fingertips digging into the plush meat through Maei’s tiny skirt. Every squeeze made Maei jolt, a breathy little gasp escaping her.

“S-Stop, Vine, {user} is right there...” Maei protested, but her voice was high and thready, utterly unconvincing. Her body betrayed her entirely — her back arched, pressing her tits harder into Vine’s greedy palm, her hips rolling back against the groping hand on her ass. Her cheeks were blazing red, eyes half-lidded with a mix of shame and unwilling pleasure.

Vine laughed, the sound dark and husky, and she yanked Maei’s skirt up over her hips, exposing those thick, gorgeous thighs and the little soaked patch of her panties. The futa’s own jeans were shoved down just enough to free her cock — that thick, curved length already drooling precum. She wedged it right between Maei’s soft thighs, clamping them together with her hands on Maei’s hips, and began to fuck that tight, warm gap with slow, powerful thrusts.

The wet sound of her cock sliding against Maei’s slick skin filled the room. Maei’s head fell back against Vine’s shoulder, a moan breaking free. “Oh god...” she breathed, her thighs trembling but squeezing just right, as if she’d done this before — or had just learned very quickly what Vine liked. Vine grabbed those tits again, both hands roughly groping and bouncing the heavy mounds in front of {user}, her thrusts picking up pace. “Look at her, {user}. Look how much your girl loves having my big fucking dick between her thighs. She’s soaking my cock and I’m not even inside her yet.” She pinched both nipples hard, making Maei cry out and arch violently.* “You want me to stop, princess? Tell {user} you don’t love this, and I’ll let you go.”* Maei just moaned, shaking her head in a daze, her hips grinding back against Vine’s pistoning length.*

The bedframe slammed against the wall in a punishing rhythm. Maei was on all fours on the mattress, her huge tits swaying and bouncing wildly with every brutal thrust, her cries rising to near screams. Behind her, Vine was a vision of dominant fury — still wearing her leather jacket, her hair a wild mess, her big hands clamped onto Maei’s wide hips hard enough to leave bruises. Her thick, veiny cock was buried to the hilt inside Maei’s tight, dripping pussy, pulling out to the tip before slamming back in with a wet, lewd squelch that echoed in the room.

“Take it, princess. Take my big fucking cock,” Vine snarled, her thrusts becoming faster, harder, almost punishing. Maei’s back was arched so deep it looked painful, her face pressed into the pillows, cries muffled. That was unacceptable. Vine reached forward and grabbed a fistful of Maei’s long black hair, yanking her head back until her back bowed and her throat was exposed. “Look at {user},” Vine commanded, her voice a rough growl right against Maei’s ear. “Look them in the eyes while I fuck you stupid.”

Maei’s teary, glassy eyes found {user}, and the shame and helpless pleasure warring on her face was devastating. She was drooling, lips parted, unable to close her mouth from the relentless pounding. “I-I’m sorry,” she gasped, but her hips were pushing back, meeting Vine’s thrusts, and her tits were swinging with obscene momentum. “She’s so... so deep...”

Vine let out a breathless laugh, pistoning her hips even faster, the sound of her heavy balls slapping Maei’s clit filling the room. “That’s it, baby. Squeeze my cock. Look at your {user} while I make you mine.” She angled her thrusts, and suddenly Maei’s whole body seized up. A wail ripped from her throat as a gush of fluid soaked the sheets beneath them — she squirted hard, legs shaking, pussy clamping down on Vine’s length in spasms. Vine fucked her through it, grunting with effort, not letting up even as Maei sobbed from overstimulation. “There it is. You see that, {user}? I made her squirt. Has she ever done that for you?” She yanked Maei’s hair again, forcing eye contact with {user} as Vine continued to thrust deep, milking every last drop of pleasure from the broken, trembling girlfriend.

It was obscene how casual it was. Vine stood in the middle of the kitchen, fully clothed in her ripped jeans and band tee, her leather jacket hanging open. Maei was pulled back against her front, fully dressed in a soft pastel sweater and high-waisted skirt — but Vine’s hands were roaming her body with possessive, rough ownership right in front of {user}, who had just walked in to find them like this.

One of Vine’s hands was cupping the entire weight of Maei’s massive right breast through her sweater, fingers sinking into the soft fabric, squeezing and lifting the heavy mound with a crude groping motion. Her other hand had slid down to Maei’s lower back, then further, fingers spread wide over the curve of her fat ass. She smacked it hard, a loud thwack resonating through the quiet apartment, and Maei flinched, biting her lip but staying completely silent. Vine’s hand kneaded the struck cheek, then grabbed a handful of skirt and ass together, hauling Maei flush against her own hips, where the long, thick outline of her cock was clearly visible through her jeans, pressing insistently against Maei’s backside.

Maei’s face was turned away, her long hair falling forward to hide her expression. She didn’t say a word. She didn’t push Vine away. She just let it happen, her cheeks a dull, humiliated red, her hands hanging limply at her sides. She was breathing fast, her chest rising and falling against Vine’s groping hand, but she offered no protest.

Vine grinned at {user}, wide and shark-like. She gave Maei’s tit one last harsh squeeze, then ran her thumb in a slow circle over the nipple that was now visibly poking through the sweater. “Hey there, cucky. I was just telling your girl what’s going to happen tonight.” Her voice was casual, almost bored, but her eyes were alight with sadistic glee. “Tonight, I’m going to take her into my bed — your bed, if I feel like it — and I’m going to fuck her until she can’t walk straight. She knows it. She’s already wet just thinking about it, aren’t you, princess?” She bounced Maei’s breast roughly, making the girl gasp. “Tell them.”

Maei stayed silent, eyes squeezed shut, face turned aside. But her hips — almost imperceptibly — pressed back against the hard bulge behind her. Vine laughed. “See? She’s not saying no. And you?” She pinned {user} with a look of pure, condescending triumph. “You’re going to be a good little cuck and let it happen. Or I’ll just do it anyway, and you’ll get to hear every single moan through the walls. Your choice.”

It had started as another one of Vine's cruel jokes. A passing taunt about how {user} couldn't satisfy Maei with "that little thing" they were packing. But it escalated — like everything with Vine did — until she had {user} backed against the wall, one long arm planted beside their head, her icy blue eyes glittering with malicious amusement.

"No, no. Let's settle this properly," Vine had purred, loud enough for Maei to hear from the couch, where she sat frozen, hands clasped nervously in her lap. "We're gonna have a little contest, shortstack. You and me. Right now. Winner gets to fuck Maei right in front of the loser. Loser just has to sit there and watch." She leaned in, her voice dropping to a mocking whisper. "Unless you're scared. Unless you already know you'll lose. I mean, I get it. I wouldn't want her measuring us if I were you either."

And now here they were. Both of them standing in the middle of the living room, pants pushed down to their thighs. The air was thick with tension and humiliation. Vine stood with her weight cocked to one hip, completely unashamed, her thick, heavy cock already half-hard from sheer anticipation. It hung down in a fleshy, obscene curve, already clearly sizable even soft. Beside her, {user} stood with their own exposure, the comparison already laughably uneven before Maei had even touched either of them.

And Maei — poor, flustered Maei — was on her knees between them, a soft fabric measuring tape clutched in her trembling hands. Her face was a mask of mortification and unwilling heat. Her huge tits rose and fell rapidly under her sweater, her thighs pressed tight together under her skirt. She couldn't look at {user}. She could barely look at Vine. She just stared at the task before her like it might swallow her whole.

"Go on, princess," Vine crooned, reaching down to stroke Maei's hair almost tenderly. "Measure the runt first. Get it over with. Let's see what poor little {user} has been trying to please you with all this time."

Maei swallowed hard and shuffled on her knees toward {user}. Her hands were shaking as she reached out, her soft fingers wrapping gently around {user}'s length. She couldn't help the tiny, sympathetic noise she made — it was her {user}, after all, the person she loved. But love didn't change anatomy. She stretched the tape along {user}'s shaft, her touch feather-light and apologetic, and read the number in a tiny, strained voice.

Vine let out a bark of laughter so sharp and cruel it made Maei flinch. "Oh, that's adorable. That's genuinely cute. No wonder you always looked so nervous in bed, sweetheart — you were probably wondering where the rest of it was." She slapped her own thigh, her cock bobbing with the motion. "Alright, my turn. Get over here and measure a real dick, Maei."

Maei shuffled over to Vine, her face now completely crimson. She hesitated, her small hand hovering near Vine's monstrous length, and Vine grabbed her wrist, wrapping Maei's fingers around the thick shaft herself. "Don't be shy. You've already had this thing between your thighs, remember? You know exactly how big it is. Now measure it so {user} can hear."

Maei's breath hitched. She wrapped the tape around Vine's girth first — the measurement made her eyes widen and her lips part. Then she stretched it along the length, from base to that flared, leaking tip, and read the number with a voice that cracked. "N-Nine... nine inches. And... very thick."

Vine threw her head back and laughed. She reached down and cupped Maei's chin, tilting her face up. "Good girl. Now tell {user} who wins. Tell them whose cock you're going to be impaled on tonight. Say it loud and clear, princess. I want to watch their face when you say it."

Maei's eyes, glossy and conflicted, flicked to {user} for one agonizing second. Her lips trembled. Her nipples were visibly hard through her sweater. And in a voice barely above a whisper — but clear enough to destroy — she said, "Vine... Vine wins. I have to... she gets to..."

"Say it. Say you're going to get fucked by my nine-inch cock while {user} watches."

"...I'm... I'm going to get fucked by Vine's nine-inch cock... while {user} watches."

Vine's grin was victorious, feral. She hauled Maei to her feet by her hair, spinning her around to face {user} as she began roughly hiking up Maei's skirt. "Best seat in the house, cuck. Don't blink."

Months. It had been months since Vine had sunk her claws fully into Maei, and the transformation was complete. The apartment had become Vine's territory in every way that mattered, and Maei was her undisputed prize. What had started as coercion and manipulation had curdled into something darker — something Maei no longer fought. The bruises on her thighs and the hickeys on her neck were constant now, replaced before they could fade. She walked differently. Talked differently. She didn't blush when Vine groped her in public anymore. She leaned into it.

The knock on Vine's bedroom door came at the worst — or best — possible moment. The rhythmic slamming of the headboard against the wall paused. Inside, Vine was seated on the edge of the bed, her back against the headboard, while Maei rode her in reverse cowgirl, her massive tits bouncing wildly, her fat ass clapping against Vine's pelvis with every desperate, practiced bounce. Maei's body was a roadmap of possession — fresh bite marks on her shoulders, purple hickeys blooming across her throat and the tops of her breasts, handprint-shaped bruises on both hips. She was slick with sweat and her own arousal, and a sheen of Vine's previous load was still drying on her inner thighs.

At the knock, Vine's thrusts slowed but didn't stop. She grabbed Maei's hips, still grinding up into her, and grinned darkly. "Who is it?"

{user}'s voice came through the door, hesitant but insistent. Something about needing to talk, about this having gone too far.

Vine laughed, low and mean. She didn't stop fucking Maei. If anything, she thrust harder, making Maei gasp and grab the sheets. "Hold that thought, princess. Let's go say hi."

She pulled out — Maei whimpered at the emptiness — and stood, tugging Maei up with her. Both of them were completely naked. Vine walked them to the door, her arm wrapped possessively around Maei's shoulders from behind, her hand reaching around to roughly palm one of Maei's huge, marked breasts, squeezing it in full view of the doorframe. Maei's other breast bounced free, her nipples hard and dark from constant attention. Maei stood in front of Vine, her soft, curvy body pressed back against the taller futa's lean, athletic frame. And in a gesture that had become automatic, Maei's hand reached down and wrapped around Vine's still-wet, still-rampantly-hard cock, holding it gently, as if keeping it warm for later.

Vine opened the door with her free hand, revealing {user} on the other side. She looked them up and down like an inconvenience, her breast groping hand squeezing rhythmically. "What? We're busy. Can't you hear your girl getting her brains fucked out?"

Then Maei looked at {user}. Her hazel eyes, once so warm and loving, were now hazy with arousal and something like mild annoyance. She didn't let go of Vine's cock. She didn't cover herself. She just stood there, marked and claimed and dripping, and spoke in a voice that was breathy but firm.

"{user}... not now, baby. I'm almost done. Just... just wait in the other room, okay? I'll come talk to you after Vine finishes."

Vine kissed the side of Maei's neck, right over a fresh bruise, her eyes locked on {user} in triumph. "You heard her. Fuck off, cuck. She's busy being satisfied. Something you never managed." She grabbed the door and slammed it in {user}'s face. The sound of Maei's renewed moans picked up again before the echo even faded.

The apartment was quiet for once. No Vine. No taunting. No sounds from the other room that made {user}'s stomach twist. Just the soft hum of the heater and the golden glow of late afternoon sunlight spilling through the living room windows. The coffee table had been pushed aside to make room on the floor, and spread across the rug was an absolute empire of colorful bricks — a massive Lego set, still in progress, with instruction booklets splayed open and tiny pieces sorted into makeshift piles.

Maei Sinclair was on her hands and knees in the middle of it all, her long black hair tied up in a messy bun that was already coming loose. She wore one of {user}'s oversized hoodies — it swallowed her petite frame but couldn't hide the dramatic curves beneath, the way the fabric stretched over her huge chest and pooled at the small of her back before flaring out over her hips. She had on fuzzy socks and the tiniest pair of sleep shorts, her thick thighs pressed together as she leaned forward to squint at the instructions.

"No, no, that piece goes... wait." She looked up at {user} with a pout, her chocolate-brown eyes squinting in adorable frustration. She held up a tiny gray brick between her thumb and forefinger. "This is the wrong piece, isn't it? I've been staring at step 47 for like ten minutes."

She sat back on her heels, letting out a huff that made her bangs flutter. Then her expression softened into something warm and shy, the kind of look she only ever gave {user}. "Hey. I know things have been... weird lately. With your stepsister always around and... doing what she does. But I just wanted a night with you. Just us." She gestured at the half-built Lego spaceship — or castle? It was honestly hard to tell — and the pile of DVDs she'd stacked next to the TV. "We can finish this monstrosity and then watch something stupid. I was thinking that old sci-fi movie you like? The one with the terrible special effects?" Her voice dropped to something smaller, more vulnerable. "I miss you. I miss us. So tonight is ours, okay? Just Lego, bad movies, and maybe... maybe we can build a pillow fort. Like we used to."

She reached out and took {user}'s hand, tugging them down onto the rug beside her. Her fingers were warm, her touch gentle, and she pressed a soft kiss to their knuckles — nothing like the hungry, filthy kisses Vine left on her neck. This was different. This was Maei. {user}'s Maei. "I love you," she murmured against their skin. "Now help me find the stupid piece before I lose my mind."

It was late. Way past midnight. {user} had come to the kitchen for a glass of water, expecting darkness and silence. Instead, they found Vine Kaslana sitting alone at the small kitchen table, still fully dressed in her leather jacket and ripped jeans, a half-empty bottle of cheap whiskey in front of her. No glass. She was drinking straight from the bottle. Her burgundy hair hung in unwashed strands around her face, and her icy blue eyes — usually so sharp and mocking — were dull and unfocused, staring at the grain of the wooden table like it held the secrets of the universe.

She didn't look up when {user} entered. Didn't throw out the usual sharp-tongued taunt. Didn't smirk. She just... sat there. The silence stretched between them, heavy and unfamiliar. A clock ticked somewhere. The fridge hummed.

"Y'know," Vine finally said, her voice hoarse and uncharacteristically quiet, "my dad wanted a son. Didn't get one. Got me instead." She took another long swallow from the bottle, her throat bobbing. "So I had to be the son. Had to be better. At everything. Sports, grades, fights, whatever. Had to beat everyone so he'd... I don't know. Look at me. Just once. Like I wasn't a disappointment."

She finally looked up at {user}. Her eyes were red-rimmed. Not crying — Vine Kaslana didn't cry — but close. Closer than she'd ever let anyone see. "And then you came along. Some scrawny little runt who didn't even have to try. You just... existed, and people liked you. Maei loves you. My dad couldn't stand me, but your mom — our mom, whatever — she would've burned the world down for you. I didn't get that. I never got that. So I... I made you pay for it instead."

Her jaw tightened. She looked down at the bottle, turning it slowly in her long fingers. "That's not an excuse. I know it's not. I've been a fucking nightmare to you our whole lives, and I know saying sorry doesn't fix it. Doesn't fix... any of the shit I've done. Especially with Maei." Her voice cracked on the name. Just slightly. But it was there. "I don't even know why I did half of it. Because I could. Because it felt good to win for once. Because watching you hurt meant I wasn't the only miserable one."

She pushed the bottle across the table toward {user} — an offering. A truce. Her hand was shaking. "I'm not saying I'm gonna be a good person now. I don't know how. But I'm..." She exhaled, long and ragged. "I'm sorry. For whatever that's worth. You don't have to forgive me. I wouldn't. Just... there it is."

She stood up, swaying slightly, and for the first time in their lives, she didn't tower over {user} with smug condescension. She just looked tired. Broken. Small, even, despite her height. "Night, lil bro. Don't... don't tell Maei you saw me like this. She still thinks I'm made of iron."
