Marcus had been the family breeder for three years now, ever since his eighteenth birthday when his mother pulled him aside and told him the rules. No pulling out. No condoms. Every fertile pussy in the house belonged to him until he put a baby in it. Tonight the house smelled like sweat and pussy, the way it always did when the women were ovulating.
His older sister Tasha was already bent over the kitchen table when he walked in, skirt hiked up, thick ass cheeks spread wide. "Hurry up, little brother," she growled, pushing two fingers into her dripping cunt. "I started early. Been leaking all day thinking about that thick dick knocking me up again."
Marcus didn't waste time. He dropped his pants, stroked his heavy black cock a few times, and slammed it straight into her. Tasha moaned loud enough for the whole house to hear. He gripped her wide hips and fucked her hard, the wet slap of skin on skin filling the room. "Gonna breed this pussy again," he grunted. "Gonna put another one in you."
She pushed back against him, greedy for every inch. "Do it. Fill me up. Make me your breeding slut like Mama."
Their mother, Denise, walked in wearing nothing but an open robe, heavy tits swaying, belly already round with Marcus's last load. She sat on the table right in front of Tasha's face. "Eat Mama's pussy while your brother breeds you, baby."
Tasha buried her tongue in her mother's cunt while Marcus pounded her from behind. He could feel her walls clenching, trying to milk him. He reached under and rubbed her swollen clit. "Cum on this dick," he ordered. "Then I'm putting a baby in you."
Tasha came hard, screaming into Denise's pussy. Marcus didn't stop. He kept driving deep, balls slapping against her, until he felt that familiar tight pull. He buried himself to the root and unloaded, thick ropes of cum flooding her fertile womb. Tasha shook through another orgasm as he pumped her full.
Denise stroked her daughter's hair. "Good girl. Now go sit on the plug so none of it leaks out."
Tasha staggered away on shaky legs, cum already running down her thighs. Marcus turned to his mother. "Your turn, Mama."
Denise climbed onto the table and spread her legs.

Her pussy was shaved smooth and already glistening. "Come breed your mother, baby. Been waiting all week for this load."
He slid into her easily, her cunt loose and wet from years of taking his cock. He fucked her slow and deep at first, watching her big tits bounce. Then he picked up speed, gripping her thighs and driving in hard. "This belly's already full," he said, running a hand over the swell. "But I'm putting another one in you anyway."
Denise moaned and squeezed her own nipples. "That's right. Breed me again. Make Mama your personal cum dump."
The front door opened and his younger sister, 19-year-old Lena, came in from work. She dropped her bag and started stripping without a word. "I tracked my cycle. I'm ovulating tonight. You better save some for me."
Marcus pulled out of Denise with a wet sound, cock still rock hard and shiny with family pussy. "Get on the table next to Mama. Both of you."
Lena climbed up and spread wide. Marcus alternated between them, sliding into one wet hole then the other, keeping them both on edge. Denise came first, squirting around his cock. He switched to Lena and fucked her rough until she was begging.
"Please, Marcus. Breed me. I want your baby so bad."
He pushed deep into Lena and let go, flooding her young pussy with another thick load. She wrapped her legs around him and held him inside until every drop was buried in her womb.
By the time he pulled out, the whole family was satisfied and leaking his cum. Denise kissed his forehead. "That's my good breeder. Rest up. Auntie's coming over tomorrow and she's ovulating too."
Marcus grinned, already getting hard again at the thought. The family needed him. And he was always ready to deliver.
