Dad was in the kitchen, clattering dishes and humming off-key to the game on the radio. Ten feet away. No door. Just an open archway and a thin wall between us and total disaster.
The living room couch was our battlefield.
Sophia had orchestrated it perfectly. She'd sent Mia to "help Dad with the dishes" for exactly three minutes while she dragged me onto the couch, hiked up her sundress, and whispered the new stakes.
"Rematch. Right here. Right now. Whoever makes you cum the most times before Dad finishes loading the dishwasher wins. Loser wears the winner's fresh creampie panties to college all week—no washing, no changing, no mercy."
Mia slipped back in like a shadow, short skirt swishing, no panties, the plug still buzzing softly in her ass on low. Her eyes narrowed at Sophia. "You're on, Mom. I'm draining him twice before you even get him wet."
They didn't waste time with foreplay.
Mia shoved me back against the cushions and straddled me reverse cowgirl, skirt flipped up, sinking down onto my cock in one slick, greedy drop. Her pussy was already soaked from dinner. The plug made her impossibly tight. She started riding immediately—slow, deep rolls so her ass barely moved, but every grind dragged her clit along my base.
Sophia knelt between my spread legs, face inches from where Mia's pussy stretched around me. She licked my balls, then dragged her tongue up the exposed shaft on every upstroke, tasting her stepdaughter's cream.
"Quiet," Sophia breathed, voice barely a whisper. "Dishwasher's running, but Dad could walk in any second. Make him cum, princess. Show Mommy how much better your tight little cunt is."
Mia smirked over her shoulder, riding faster now, ass cheeks rippling under the skirt. "Feel that, little bro? I'm gonna milk the first load before Mom even gets a turn."
The dishwasher hummed louder. Dad's humming got closer.
I grabbed Mia's hips and thrust up, burying myself to the hilt. She bit her lip hard to stay silent, pussy fluttering wildly. Sophia sucked one of my balls into her mouth, humming, and that was it—I exploded. Thick ropes pumped deep into Mia while she ground down hard, thighs shaking, her own silent orgasm ripping through her.
"One for me," Mia whispered triumphantly, still impaled. She lifted off just enough for a thick glob of my cum to drip onto Sophia's waiting tongue.
Sophia swallowed with a wicked smile, then yanked Mia off me. "My turn."
She spun around and sank down cowgirl, facing me, heavy tits bouncing inside her sundress as she rode with slow, controlled rolls. Her experienced pussy squeezed me like a velvet fist, rippling in waves that made my eyes roll back. Mia knelt beside us, one hand on Sophia's clit, the other reaching back to crank the plug remote in Sophia's bra.
"Faster, Mom," Mia taunted, voice low. "Dad's almost done in there. I want to see you lose it while he's drying the plates."
Sophia's hips sped up. The couch creaked once—loud enough that we all froze. Dad's humming paused.
We held our breath. Sophia kept riding, slower now, but deeper, grinding her clit against me on every circle.
The humming resumed.
I grabbed Sophia's tits through her dress and pinched her nipples hard. She came with a tiny, choked whimper, pussy clamping down and milking me straight into a second orgasm. I flooded her, pulse after pulse, so much that it immediately started leaking out around my shaft and onto my balls.
"Two for Mommy," Sophia gasped, victorious, still rocking through the aftershocks.
Mia's eyes flashed pure brat rage. She shoved Sophia off, climbed on, and rode me like she was trying to break the couch—fast, brutal, ass clapping under her skirt while she whispered filthy threats.
"You're gonna give me the tie-breaker right now. I'm wearing your cum-soaked panties to every lecture this week if I lose, but I'm not losing."
Sophia reached between us, fingers rubbing Mia's clit and my shaft at the same time. The dishwasher clicked off. Dad's footsteps moved toward the living room.
"Cum," Sophia ordered both of us. "Right fucking now."
Mia slammed down one last time. I erupted inside her—third massive load of the night—while she came with me, biting my shoulder to stay silent. Sophia caught the overflow on her fingers and licked them clean just as Dad stepped into the archway.
He paused. "You kids watching the game?"
Mia was still on my cock, skirt covering the evidence, pussy still fluttering around me. Sophia sat beside us like nothing happened, legs crossed, my fresh cum slowly dripping down her own thigh under her dress.
"Just relaxing, Dad," Mia said sweetly, voice only a little breathless. "Long week at college."
Dad grunted and headed upstairs. The second his footsteps faded, Mia slid off me, a river of my cum pouring out of her and onto the couch cushion.
Sophia scooped some up, smeared it across Mia's lips, then kissed her deep and messy.
"Three each again," Sophia murmured against her mouth. "Tie. But the panties rule still stands. Tomorrow you both wear each other's creampie thongs to campus. All week. And Mommy gets to watch you squirm in every lecture."
Mia grinned, licking my cum from Sophia's fingers. "Fine. But next rematch is on your marital bed while Dad's asleep downstairs. I'm winning that one."
Sophia's eyes sparkled with pure filth.
"The rivalry just got a lot stickier."
