I walked into the house after a long day and knew right away something had changed. Mom was in the kitchen wearing nothing but an apron, her big tits spilling out the sides, nipples hard. My older sister Lisa was bent over the counter in just a thong, ass cheeks spread, while my younger sister Emma knelt on the floor sucking on a popsicle like it was a cock. They all looked at me with that hungry look I had been waiting for.
"Strip, baby," Mom said, voice low and dirty. "We've been talking. You own us now. All three of us. Your personal incest harem."
My cock went rock hard in seconds. I dropped my pants and let it spring out, thick and already leaking. Mom dropped to her knees first, wrapping her soft lips around the head and sucking hard. She took me deep, gagging when it hit the back of her throat, spit running down my balls. Lisa came over and started licking my shaft while Mom worked the head, their tongues meeting in sloppy kisses around my dick.
Emma crawled between my legs and licked my balls, sucking one then the other into her warm mouth. "Fuck, your cock tastes so good, big brother," she moaned. I grabbed Mom's hair and started fucking her face, thrusting hard while the other two watched and fingered themselves.
We moved to the living room. I put Mom on all fours on the couch and slammed into her wet pussy from behind. She was soaked, dripping down her thighs. "Yes, fuck your mother's cunt," she begged. Lisa sat in front of her so Mom could eat her pussy while I pounded away. Emma climbed onto the back of the couch and lowered her shaved pussy onto my mouth. I licked her clit fast, tongue fucking her hole while I drilled Mom's tight snatch.
I switched to Lisa next, bending her over the arm of the couch and ramming into her from behind. Her ass jiggled with every thrust. Mom and Emma knelt beside me, licking my cock every time it slid out of Lisa's pussy, tasting her juices mixed with my precum. "Share that dick," Mom ordered. They took turns sucking me clean before I shoved back inside Lisa.
Emma wanted it rough. I laid her on the floor and fucked her missionary, legs pushed back to her shoulders so I could go balls deep. She screamed and came hard, squirting around my cock. Mom sat on her face while I fucked her, grinding her pussy on Emma's tongue. Lisa straddled Emma's tits and rubbed her clit against them, leaving wet streaks.
We kept going for hours. I came in Mom's pussy first, filling her up until cum leaked out around my shaft. Then I pulled out and made Lisa and Emma lick it clean from her. I fucked Lisa's ass next, stretching her tight hole while she ate Mom's creampie. Emma rode my face again, coming twice more.
By the end they were all marked with my cum. Mom's tits had ropes across them. Lisa's ass was red from spanking. Emma's face was glazed. They curled up around me on the floor, licking and sucking softly to keep me hard.
"Tomorrow we do it again," Mom whispered, stroking my cock.

"Your harem isn't going anywhere."
I smiled and pulled them closer. This was just the start.
