I was on my bed with my cock in my hand, phone open to another free adult mom son sex stories thread, when the door swung open. Mom stood there in her thin robe, eyes locked on my throbbing dick and the screen full of dirty captions about sons pounding their mothers.
"What the fuck are you looking at?" she said, voice low and rough. She didn't leave. She stepped inside and shut the door.
I froze, fist still wrapped around my shaft. "Nothing. Just some stories."
She walked over, grabbed the phone, and read the first line out loud. "My mom walked in on me jerking off and decided to sit on my cock instead." Her eyes flicked to mine. "That what you want?"
My dick twitched hard. "Yeah."
Mom dropped the robe. Her tits were heavy, nipples already stiff. She had a soft belly and wide hips, and her pussy was shaved smooth. She climbed onto the bed, grabbed my wrist, and pulled my hand off my cock.
"You've been reading that shit every night," she said. "I heard you moaning my name through the wall." She wrapped her fingers around my dick and gave it a slow, tight stroke. "Time to stop reading and start fucking."
She straddled my thighs, rubbed the head of my cock against her wet slit, and sank down in one smooth motion. Her pussy was tight and hot, gripping me all the way to the balls.
"Fuck," I groaned.
Mom started riding. No slow build-up. She slammed her ass down hard, tits bouncing, pussy making wet slapping sounds every time she took the full length. "This what those stories got you off on? Your mom’s cunt squeezing your cock?"
I grabbed her hips and thrust up to meet her. "Yes. Fuck yes."
She leaned forward, hands on my chest, and ground her clit against me while she rode.

"Tell me what you read."
"I read about sons filling their moms up," I said, voice ragged. "About moms begging for it raw."
Mom clenched around me. "Then do it. Fill this pussy up like you’ve been jerking off to."
I flipped her onto her back, hooked her legs over my shoulders, and drove in deep. Her cunt was soaked, juices running down to her ass. I fucked her hard and fast, the way the stories always described. Mom’s moans got louder, dirtier.
"Harder," she demanded. "Pound your mother’s cunt. Make it yours."
I slammed into her until the bed creaked. Her pussy fluttered and she came hard, nails digging into my arms, yelling my name. I didn’t stop. I kept fucking her through it, chasing my own orgasm.
When I was close I pulled out, flipped her onto her stomach, and shoved back in from behind. I gripped her ass and pounded until I unloaded deep inside her, pulse after pulse of cum flooding her pussy.
Mom pushed back against me, milking every drop. "That’s it. Give it all to me."
We stayed like that for a minute, breathing hard. Then she rolled over, spread her legs, and showed me the mess leaking out of her.
"Next time you want free adult mom son sex stories," she said, "you come straight to the source."
I was already getting hard again.
