I walked through the door after a long day and there she was, my mother, bent over the kitchen counter in nothing but an apron, her bare ass cheeks spread slightly as she wiped the surface. She froze when she saw me. "Honey, I didn't hear you come in," she stammered, but I was already done waiting.
"Strip the apron. Now." My voice came out low and hard. She blinked, cheeks flushing, but her hands moved to the tie and let it fall. Her tits spilled out, nipples already stiff, and her shaved pussy glistened under the lights. She had been waiting like this. Good.
"On your knees, Mom. Mouth open." She dropped without another word, crawling the few feet to me. I unzipped and pulled my cock out, already thick and heavy. She took it straight down her throat like the obedient slave she was becoming. No hesitation, just wet sucking sounds as she bobbed, spit running down her chin and dripping onto her tits. I grabbed her hair and fucked her face harder, balls slapping her chin until she gagged and tears streaked her makeup.
When I pulled out she gasped for air, strings of saliva connecting her lips to my shaft. "Please, use me," she begged, voice hoarse. "I'm your fucktoy now. Your mom slut."
I hauled her up by the hair and bent her over the table. Her ass was up, legs spread, cunt dripping down her thighs. I slammed into her in one thrust, burying every inch in that tight, hot pussy. She cried out, pushing back to take me deeper. "Harder, son. Fuck your slave harder." I did, pounding her so the table legs scraped the floor. Her tits swung and slapped the wood with every thrust. I reached under and pinched her clit until she came, pussy clenching and squirting around my cock.
I didn't stop. I pulled out, spat on her asshole, and shoved two fingers in while I kept fucking her cunt. "This hole's mine too," I told her. She moaned and nodded, pushing back. After she came again I switched, pressing the head of my cock against her tight ring and sinking in slow until my balls rested against her ass. She whimpered and begged for more, so I railed her ass until she was shaking and babbling that she was nothing but my cumdump.
We moved to the living room. I had her ride me on the couch, her big tits bouncing in my face while she repeated, "I'm your sex slave, I'm your incest whore, use Mommy however you want." I flipped her onto her back, legs over my shoulders, and fucked her deep until I filled her pussy with a thick load. She clenched and milked every drop, then slid down to clean my cock with her tongue, licking our mixed cum off me like it was dessert.
By the end of the night she was collared with my belt, on all fours, ass plugged and pussy leaking while she thanked me for owning her. She slept at the foot of my bed, ready for morning use.

From that day on, every time she heard my voice she dropped whatever she was doing, stripped, and presented herself. My mother, my personal incest sex slave, dripping and desperate for whatever I wanted to do to her holes. She never said no. She only said "yes, Master. Use your mom."
