Mom's heavy balls slapped against my ass with every thrust, her thick futa cock stretching my cunt wide open. At twenty-two I knew exactly what I was doing when I climbed into her bed that night, legs spread, begging for it. She was forty-five, still built like a tank with those wide hips and that veiny dick that hung halfway down her thigh when soft. Tonight it was rock hard and already leaking.
"Fuck, baby girl, your pussy's sucking me in," Mom growled, gripping my hips and slamming deeper. No slow buildup, just raw need.

Her cockhead punched against my cervix on every stroke, precum mixing with my juices and dripping down my thighs. I pushed back, taking every inch, moaning like a slut because that's what I was for her.
"Knock me up, Mom. Breed this hole. Fill me with your cum until it takes." The words came out filthy and desperate. She loved when I talked like that. Her hand reached around to rub my clit in rough circles while she pounded me from behind, the bed creaking under us. Sweat slicked our skin. Her heavy tits pressed against my back as she leaned over, teeth on my shoulder.
She pulled out just long enough to flip me onto my back, spreading my legs wide. Her cock glistened with our mess, the head flared and angry red. She shoved back in one smooth thrust, balls deep, and started jackhammering. The wet sound of her cock ruining my pussy filled the room. I grabbed her ass, pulling her harder, feeling those heavy nuts swing and slap.
"Gonna breed you tonight," she grunted, eyes locked on mine. "Gonna pump this daughter cunt full until you're swollen with my load. Your belly's gonna grow with my kid." The dirty talk pushed me over. I came hard, cunt clenching and squirting around her shaft, but she didn't stop. She fucked me straight through it, using my spasming hole like a fleshlight.
Her rhythm turned erratic. She buried herself to the root and held there, cock pulsing as thick ropes of cum blasted straight into my womb. It was hot, endless, overflowing almost immediately and leaking out around her shaft. She kept grinding, milking every drop, making sure it stayed deep.
We didn't pull apart. She stayed inside me, cock softening slowly while her cum worked its way in. "Keep your legs up," she ordered, voice hoarse. "Let it settle." I obeyed, holding my knees to my chest, feeling the warm flood inside. Round one done, but Mom's futa stamina meant she was already twitching back to life.
She pulled out, cum pouring from my gaping pussy, and shoved two fingers in to push it deeper. Then she straddled my face, feeding her half-hard cock between my lips. "Clean it. Taste how good our breeding tastes." I sucked greedily, licking her shaft and balls clean while she fingered more cum back inside me. By the time she was hard again she flipped me onto all fours and mounted me once more.
This round was slower but deeper, her cock stirring the cum already packed in my cunt. She reached under to squeeze my tits, pinching my nipples while she whispered more filth. "Gonna fuck you every night until the test turns positive. Your sister's next after you. Family tradition." The thought of my older sister getting the same treatment made me clench again. Mom felt it and laughed low, fucking harder.
She came a second time, even more cum than the first, flooding me until my belly felt full. We collapsed together, her cock still plugged inside to keep everything in. Hours later she woke me with her mouth between my legs, licking her own cum out before sliding back in for round three. By morning my pussy was wrecked, cum crusted on my thighs, and I knew I'd be walking funny for days.
Mom kissed my forehead before work. "Same time tonight. Bring the plug so none leaks out." I smiled, already planning how I'd beg her to breed me again. The family secret was out in the open between us now, and neither of us wanted it any other way.
