The house was quiet when I got home from work, but I knew she was waiting. Mom had been giving me those looks for weeks, the ones that said she wanted more than just dinner on the table. At twenty-five, I was done pretending. I wanted to fuck my own mother and put a baby in her.
She was in the kitchen wearing that thin robe, nothing underneath. Her tits pushed against the fabric, nipples hard. "You're home late," she said, voice low. I walked right up, grabbed her ass, and pulled her against my hard cock.
"Stop talking," I growled. I untied the robe and let it fall. Her body was perfect, soft curves, shaved pussy already wet. I bent her over the counter and slapped her ass hard. "You've been teasing me with this cunt for too long."
Mom moaned as I shoved two fingers inside her. She was dripping. "Fuck me," she begged. "I need it raw tonight."
I dropped my pants and slammed my thick cock into her from behind. No slow start, just deep, hard thrusts that made her scream. Her pussy gripped me tight, wet and hot. I reached around and rubbed her clit while I pounded her, balls slapping against her.
"Yes, fuck your mother," she gasped. "Fill me up."
I pulled out, spun her around, and lifted her onto the counter. Spreading her legs wide, I drove back in, watching my cock stretch her open. Her tits bounced with every thrust. I leaned down and sucked on her nipples, biting just enough to make her cry out.
We moved to the couch.

She climbed on top, riding me reverse so I could watch her ass bounce. "Deeper," I ordered, grabbing her hips and slamming her down on my shaft. Her juices ran down my balls. I reached up and pinched her nipples, twisting them while she fucked herself on my cock.
"I'm gonna breed you," I said, voice rough. "Gonna pump this pussy full until you're pregnant with my kid."
Mom moaned louder, grinding harder. "Do it. Cum inside me. Make me your pregnant slut."
I flipped her onto her back, legs over my shoulders, and fucked her like an animal. Sweat dripped off us. The sound of skin slapping filled the room. Her pussy clenched around me as she came, squirting a little on my stomach. I kept going, chasing my own release.
When I was close, I buried myself balls-deep and let go. Thick ropes of cum shot into her, flooding her womb. I stayed inside, pulsing, making sure every drop stayed where it belonged. She milked me with her walls, eyes locked on mine.
We didn't stop there. After a short rest, I took her to the bedroom. She got on all fours and I fucked her doggy style again, slapping her ass red while I pumped another load deep. Then she sucked me clean, tasting our mixed juices, before I bent her over the bed and came in her a third time.
By morning, she was leaking my seed down her thighs. We kept at it for days, raw and nonstop. Every time I finished inside her, I told her she was going to be pregnant soon. She begged for it, spreading her legs wider, pushing her hips back to take every inch.
Weeks later, the test was positive. Her belly would grow with my child, our secret. The sex only got dirtier after that, knowing what we'd done. She was mine now, bred by her own son, and neither of us wanted it any other way.
