The roar of the crowd on TV echoed through the dimly lit living room like a thunderclap, the scent of popcorn and spilled beer hanging heavy in the air from Maya's solo tailgate setup on the couch. At 20, she was a pint-sized firecracker of a stepsister—petite frame swallowed by an oversized team jersey that hit mid-thigh, the fabric clinging to her perky B-cups and flaring over the curve of her ass, her wild auburn waves tied in a messy bun that screamed "I don't give a fuck." She'd been glued to the screen all afternoon, cheering and cursing with a passion that made Chad Alva, her 22-year-old stepbrother, pause in the hallway, his gym bag slung over one shoulder, sweat still beading on his temple from his workout. He wasn't much for sports, but seeing her like that—legs tucked under her, jersey riding up to flash the edge of her boy shorts—stirred something primal in his gut, a heat that had nothing to do with the game."Yo, Maya—rooting for the underdogs again?" Chad teased, dropping his bag with a thud and sauntering in, his gray tank top clinging to the ridges of his abs, basketball shorts doing little to hide the growing interest in his gaze. She glanced up, rolling her eyes but smirking, her freckled nose wrinkling in that way that always got under his skin. "Damn right. Your team's trash—watch and learn, bro." The sibling ribbing was routine, a veil over the tension that had simmered since their parents' shotgun wedding two years back: stolen glances in the kitchen, accidental brushes in the hall that lingered too long, the kind of forbidden spark that made late-night showers a necessity.Chad flopped onto the couch beside her, close enough that his thigh pressed against hers, the heat of his body cutting through the jersey's thin fabric. "Bet you ten bucks they choke in the fourth." Maya's laugh was sharp, competitive, her eyes flicking to him with that challenging glint. "You're on. But make it interesting—what do I get if I win?" He leaned in, voice dropping low, his breath ghosting her ear. "Anything you want. And if I win... you do anything I want. No backsies." She paused, the game's roar fading to white noise, her pulse kicking up at the husky edge in his tone, the way his gaze dipped to the V-neck of her jersey, tracing the freckles spilling down her chest. "Deal. Loser handles the chores for a week." Handshake sealed it—her small palm in his large one, lingering a beat too long, electricity crackling between their fingers.The game dragged on like a fever dream—close calls, buzzer-beaters, Maya's cheers turning to groans as Chad's team clawed back. By the final whistle, his grin was triumphant, predatory, as the scoreboard lit up in victory. "Pay up, sis." Maya huffed, tossing the remote aside, but there was a spark in her eyes—curiosity, maybe, or the thrill of the unknown. "Fine. What do you want? Dishes? Laundry?" Chad's smile turned wolfish, his hand catching her wrist as she moved to stand, pulling her back down beside him—close, too close, the jersey riding up to bare the lace edge of her shorts. "Not that. I want you... naked. On your knees. Tending to this."Her breath caught, eyes widening as he unzipped his shorts, freeing his cock—thick and veined, curving upward with a flush that matched the heat creeping up her neck, already half-hard from the proximity, the tension that had been building for months. "Chad... we're—" But he cut her off with a thumb to her lips, voice rough and commanding. "Steps. Not blood. And you lost fair. Now be a good girl and pay up." Maya's heart hammered, a traitorous throb pulsing between her thighs, soaking her shorts as she sank to her knees between his legs—slow, deliberate, the jersey pooling around her like a surrender flag. "Fuck... okay. But just this once."She peeled the jersey off first—baring her lithe body inch by inch, perky tits bouncing free, nipples hardening in the cool air, freckles trailing down her flat stomach to the damp spot on her shorts. Chad groaned, hand fisting his length as she shimmied out of the shorts and thong, kicking them aside to kneel fully naked before him—smooth skin glowing in the TV's flicker, her auburn waves framing a face flushed with equal parts shame and hunger. "Like this?" she whispered, voice husky, as her small hand wrapped around his base—stroking tentative at first, then bolder, thumb smearing the bead of pre-cum over the crown. Chad's head fell back, a guttural "Fuck yes" escaping as she leaned in, lips parting to swirl her tongue around the tip—salty and hot, drawing a hiss from his throat.She took him deeper—lips stretching wide around his girth, cheeks hollowing with suction that had him bucking, her free hand cupping his balls to roll them gently as she bobbed, gagging softly when he hit the back of her throat. "God—Maya, that mouth... suck your stepbro's cock like a champ." Spit trailed down his shaft in glossy streaks, her tits jiggling with each pass, nipples brushing his thighs as she hummed vibrations around him, eyes watering but locked on his—wide, daring, the taboo thrill making her pussy clench emptily, juices dripping down her inner thigh. Chad fisted her hair, guiding her rhythm—thrusting shallow to fuck her face, the wet glurks filling the room like a filthy soundtrack, her gags turning to moans as she ground her clit against her heel for friction."Enough," he rasped, pulling her off with a pop—strings of saliva connecting her swollen lips to his tip—hauling her up to straddle his lap, her slick pussy sliding against his length in a teasing grind. "Ride me—show me how bad you want to pay that bet." Maya whimpered, rising to notch him at her entrance—sinking down slow, her tight heat enveloping him inch by scorching inch, walls fluttering like silk flames around his girth. "Oh fuck— so big—stretching me!" She bottomed out with a gasp, hips circling to grind her clit against his pelvis before bouncing hard—tits heaving with each thrust, ponytail of waves whipping as she rode him like a storm, the couch creaking under them. Chad's hands mauled her ass, spanking the cheeks until they pinked, pulling her down to latch onto a nipple—sucking hard, teeth grazing the peak as she cried out, "Yes—Chad, fuck your stepsis—deeper!"Reverse cowgirl blurred next—her spinning atop him, impaling herself anew, ass rippling against his thighs as she bounced wild, ponytail swaying, the angle letting him watch her pussy swallow him whole, juices coating his balls. "Take it—ride that dick like you stole it." She did, grinding back until another orgasm ripped through her—thighs quaking, walls spasming in waves that milked him relentless. Spooning on the couch—intimate and torturous—his chest to her back, cock sliding home from behind in lazy, grinding strokes while his hand dipped to rub her clit, fingers scissoring her through a shuddering peak that had her sobbing his name.Doggy sealed it—her on all fours, ass high as he mounted her from behind, slamming in with a grunt that shook the frame, hands gripping her hips to pull her onto him like a ragdoll, spanking her cheeks red between thrusts. "Gonna cum—where, sis?" Maya ground back, wailing—"Inside—fill me, Chad—creampie your naughty stepsister!" But he pulled out with a roar, fisting his slick length to erupt: ropes of hot, thick seed painting her ass and back in pearly streaks, dripping down her crack to tease her still-fluttering pussy. She collapsed forward, spent and smirking, fingers dipping back to scoop the cum, sucking it clean with a moan. "Bet paid... but next game's on me?"Chad chuckled, pulling her into his lap, still hard against her thigh. "You're on. Loser strips first." In the afterglow, with the game long forgotten and the living room reeking of them, Maya had lost more than a bet. And damn if it wasn't the best defeat ever.
