I turned eighteen last week and the house was empty except for me and Mom. She had that look in her eye all day, the one that said she was done pretending. After dinner she locked the door, turned to me in the kitchen, and said, "Strip. Now. It's your birthday and I'm giving you what you've been jerking off about for years."
My cock was already hard before my pants hit the floor. Mom pulled her robe open and there was nothing underneath, just smooth skin, heavy tits, and a shaved pussy that looked wet already. She dropped to her knees right there on the tile and wrapped her hand around my dick.
"Happy birthday, baby," she growled, then shoved the whole thing in her mouth. No teasing. She sucked like she was starving, spit running down her chin while she worked the shaft with both hands. I grabbed her hair and fucked her face, balls slapping her chin, and she moaned around me like she loved every second.
When she stood up she bent over the kitchen table, ass up, legs spread. "Fuck your mother," she said. "Fill the cunt that made you."
I slammed into her in one thrust. She was tight and burning hot inside. I pounded her hard, the table legs scraping the floor, her tits mashed against the wood. Every slap of my hips made her moan louder. "That's it, fuck me like you own me," she hissed. "Deeper. Wreck that pussy on your birthday."
I reached under and rubbed her clit while I drilled her. She came fast, cunt clenching around my cock, juices running down her thighs. I didn't stop. I kept slamming until I felt my balls tighten, then pulled out and shot thick ropes across her ass and lower back. She reached back and rubbed my cum into her skin like lotion.
We weren't done. She dragged me to the couch, pushed me down, and climbed on top. She sank onto my cock again, riding me reverse so I could watch her ass bounce. "You like watching Mommy fuck you?" she asked, grinding down hard. "You like this tight incest cunt?"
I grabbed her hips and thrust up to meet her. She leaned forward, hands on my knees, and worked her ass in circles. I could see my cock disappearing into her over and over, shiny with her cream. She reached down and fingered her clit while she rode, coming again with a loud cry, her walls pulsing around me.
I flipped her onto her back, hooked her legs over my shoulders, and fucked her deep. She clawed my back and begged for more. "Come inside me this time," she panted. "Fill Mommy up on your birthday."
I buried myself to the hilt and unloaded. Pulse after pulse of hot cum pumped straight into her.
She held me there, milking every drop, then pulled me down for a filthy kiss while my cock still twitched inside her.
Later she made me fuck her again in the shower, bent against the tiles with hot water running over us. By the end of the night my cock was sore, her pussy was swollen and leaking, and we both knew this was just the start of a very dirty new chapter.
