Dad was sprawled in the living room recliner, TV blaring some loud action movie, volume cranked high enough to shake the floorboards. Perfect cover.
Sophia had left the master bedroom door wide open on purpose—just a crack, but enough that the risk felt like a live wire under our skin. The marital bed was still rumpled from last night's quickie, the sheets faintly stained with the evidence of our last two loads. She stood at the foot of it completely naked, heavy tits swaying, phone already propped on the nightstand in 4K mode and recording.
"Biggest Creampie Contest," she announced, voice low and silky. "Rules are simple, babies. We edge Alex until his balls feel like they're going to burst. Then we ride him one at a time—deep, slow, no rushing. Whoever makes him shoot the single thickest, heaviest, longest load wins. Loser has to push the winner's creampie out on camera and wear it in her panties all day tomorrow. Dad's right downstairs. One loud moan and we're all fucked."
Mia's bratty smirk was pure venom. She stripped off her tiny skirt and crop top, climbed onto the bed on her back, and spread her legs wide. "I'm going first. I'm tighter, I'm wetter, and I've been training for this. You're gonna watch your stepson flood my womb while Dad thinks we're all asleep."
Sophia just smiled that calm, predatory smile and lubed two fingers before sliding them into Mia's already dripping pussy. "Bratty as ever. Fine. You get first ride. But Mommy's going to edge him with my throat while you warm him up."
I lay back on Dad's side of the bed, cock rock-hard and leaking. Mia straddled me reverse cowgirl, ass facing the camera, and sank down in one smooth, greedy glide. The plug was still buzzing on low inside her, making her walls flutter around every inch.
"Fuck… he's already throbbing," she moaned, starting to ride slow and deep. Her ass clapped softly against my thighs—quiet, controlled, but filthy. Sophia knelt between my spread legs and swallowed my balls, sucking gently while her tongue teased the sensitive skin right behind them.
They worked in perfect rivalry. Mia rolled her hips in tight circles, squeezing her pussy on every downstroke. Sophia hummed around my balls, then popped off to lick up the shaft where it disappeared into Mia, tasting her stepdaughter's cream and whispering coaching.
"Slow down, princess. Feel how full his cock is? We're building the biggest load yet. Grind… just like that. Good girl."
Mia's competitive side kicked in hard. She slammed down harder, the wet schlick of her soaked pussy echoing softly. "He's gonna explode in me first. I can feel it. My pussy's gonna milk him dry while Dad's watching explosions on TV."
The edging went on for twenty agonizing minutes. They switched—Sophia mounting me cowgirl, her experienced cunt rippling and squeezing in waves that made my toes curl. Mia took over the ball-sucking, then deepthroated me between Sophia's strokes, gagging quietly for the camera.
My balls felt swollen, heavy, aching. Pre-cum was pouring out of me in a steady stream.
"Enough," Sophia finally whispered, eyes dark with lust. "Time for the finale. Mia, you ride first. Make him cum. Then I get the second round and we compare."
Mia slammed down and rode like a demon—fast, brutal, ass bouncing while she stared straight into the camera. "Cum for me, little bro. Give your stepsister the biggest fucking load of your life. Breed me right on Mom's marital bed."
Sophia rubbed Mia's clit and my shaft at the same time, whispering, "Let it go, baby. Flood her. I want to see it overflow on camera."
I exploded.
The first rope was so thick and powerful it felt like it punched straight into Mia's womb. Rope after rope followed—long, heavy, endless—pumping so much cum that it immediately started squirting out around my shaft and soaking the sheets beneath us. Mia came with a choked whimper, thighs shaking, pussy milking every last drop while the camera caught the creamy overflow in perfect 4K.
She lifted off slowly. A massive, thick glob of my cum poured out of her stretched hole like a waterfall, dripping onto the bed in heavy white strands.
Sophia's eyes widened with hungry approval. "My turn. Watch Mommy take even more."
She mounted me immediately, sinking down onto my still-hard, cum-slick cock. Her pussy was hotter, wetter, and somehow even greedier after watching Mia. She rode with slow, deep grinds, belly already bulging slightly from the sheer volume I'd just given her daughter.
"Give Mommy the rest," she purred, rolling her hips. "I want the record-breaking load. The one that leaks out of me for days."
Mia knelt beside us, fingering Sophia's ass and trash-talking. "You're not gonna beat that, Mom. I felt how much he gave me. You're just getting sloppy seconds."
But I was already there again. The rivalry, the risk, the camera, Dad snoring downstairs—it all hit at once. I grabbed Sophia's wide hips and thrust up hard, exploding a second time. This load was somehow even bigger—thicker, longer ropes that made Sophia's eyes roll back and her belly visibly swell as I pumped her full.
When she finally lifted off, the creampie was obscene. A river of thick white cum gushed out of her, pooling on the sheets between her thighs. She reached down, spread her pussy lips for the camera, and pushed—another heavy glob splattering out in a filthy, slow-motion waterfall.
Sophia looked straight into the lens, cum dripping from her chin where she'd tasted it, and smiled.
"Mommy wins this round," she whispered. "Biggest load ever. But we'll let the camera decide tomorrow when we watch it back."
Mia glared, but her pussy was visibly clenching at the sight. "Rematch tomorrow. On the kitchen island. While Dad's eating breakfast in the next room."
Sophia leaned down and kissed Mia deep, sharing the taste of my cum, then kissed me the same way.
"Rivalry officially level: nuclear. The video vault is going to need more storage."
Dad's movie kept playing downstairs, explosions masking the wet sounds of two dripping pussies and one very satisfied cock.
