The sun was low and golden, painting the backyard in hazy orange light that made everything feel both filthy and romantic. No fence on the back side—just open grass, a few trees, and the distant possibility that any neighbor with binoculars could catch a glimpse if they really tried.
Sophia didn't care.
She'd dragged the big outdoor lounge bed into the middle of the yard, stripped completely naked, and set up three phones on tripods for 360-degree coverage. The marathon on the marital bed had left us sore but hungry for more, and Sophia's eyes glowed with that next-level predator energy.
"Backyard rules," she announced, voice carrying across the grass. "No clothes. No hiding. No holding back. The neighbors might see. The cameras are rolling. And the only goal is to make Alex cum as many times as humanly possible before the sun goes down. Loser of the final count wears both our creampies under her dress when we go grocery shopping tomorrow."
Mia dropped her robe the second she stepped outside. Sunlight hit her skin like a spotlight—perky tits, tight waist, the remote plug and egg still buried inside her. "You're going down, Mom. I'm riding him until he's shooting blanks. And I want the neighbors to hear me scream when I win."
Sophia just smiled and lay back on the wide lounge bed, legs spread wide, heavy tits catching the sunset light. "Then come prove it, princess. Alex, start with Mommy. Mia, you sit on my face while he fucks me. Let's give the backyard a proper show."
I stepped between Sophia's thick thighs and sank into her in one long, smooth thrust. She was soaked, velvet heat rippling around every inch. Mia swung a leg over Sophia's face and lowered her dripping pussy right onto her stepmom's mouth, grinding down hard while looking straight into the nearest camera.
"Fuck her, little bro," Mia moaned, already riding Sophia's tongue. "Fill Mommy while she eats my creampie from this morning. I want the neighbors to see how well we've corrupted this family."
The bed creaked under us as I started pounding Sophia—deep, powerful strokes that made her heavy tits bounce. The sunset light turned everything golden and obscene: Mia's ass flexing as she rode Sophia's face, Sophia's throat working visibly while she moaned into her stepdaughter's pussy, my cock disappearing into Sophia's stretched hole again and again.
Mia reached down and cranked both remotes to max. The toys buzzed loud enough to carry on the evening air. Sophia's hips bucked wildly. She came hard, pussy clamping down like a vice, milking me straight into my first backyard load. Thick ropes pumped deep while Mia screamed her own orgasm on Sophia's tongue, thighs shaking, juices running down Sophia's chin.
Round 1: Sophia – 1, Mia – 1 (tie).
They switched instantly.
Mia took the center spot, ass up, face buried between Sophia's thighs in a 69. I slammed into Mia from behind, the plug and egg still buzzing inside her, making her even tighter. The outdoor air felt electric on our skin. Every moan carried. Every wet slap echoed.
"Harder—fuck—breed your stepsister in the open!" Mia cried, voice loud and shameless. "I want the guy across the street to jerk off watching me take your load!"
Sophia fingered Mia's clit and my balls at the same time, coaching through moans. "Give it to her, baby. Flood her right here where the whole neighborhood can see. Make it the biggest load of the day."
I exploded again—second massive creampie of the evening—pumping so deep into Mia that it pushed out around my cock and dripped onto the lounge cushion in thick white strings. Mia came with a scream that definitely carried to the next yard over.
The sun dipped lower. The rivalry got nastier.
We rotated positions for hours—Sophia riding me reverse cowgirl while Mia sat on my face, Mia bouncing on me while Sophia deepthroated me between strokes, both of them grinding on my cock together in a double cowgirl stack. Toys got swapped, remotes got cranked, and the cameras caught every filthy angle.
By the time the sky turned deep purple, I'd lost count. My balls ached. The lounge bed was soaked. Both women were leaking rivers down their thighs, laughing and trash-talking between orgasms.
Sophia finally called it when the first porch light flicked on across the street.
"Final count," she panted, cum dripping from her chin. "Mia: nine loads. Mommy: eight. Princess wins by one."
Mia threw her arms up in victory, cum running down her legs, and struck a pose for the cameras. "Told you. I own this backyard now."
Sophia pulled us both down into a sticky, sweaty pile on the ruined lounge bed and kissed us slow and deep.
"Backyard conquered," she whispered, voice hoarse. "Tomorrow we move the training inside again—but this time we're filming in Dad's office while he's on his video call from Singapore. The corruption keeps climbing."
Mia grinned, still leaking, and looked up at the darkening sky.
"Two weeks of freedom and we've already turned the whole house plus the backyard into our personal porn set. I can't wait to see what Chapter 48 looks like."
Sophia just smiled wider and turned the remotes back on inside Mia for the walk back inside.
"Neither can I, babies. Neither can I."
