I walked into the kitchen that night and saw Mom bent over the counter in nothing but a thin tank top and panties. Her ass was thick and round, the fabric riding up to show the crease where her cheeks met. She was 44, still hot as hell, and I was 21, home from college for the summer with a cock that wouldn't quit thinking about her.
"Fuck, Mom," I said, voice low. "You can't dress like that around me."
She turned, tits straining against the tank, nipples hard. "And why not, baby? You think I don't notice how you stare at my body every damn day?"
I didn't answer with words. I stepped up, grabbed her hips, and spun her back to the counter. My hands slid down, yanking those panties aside. Her pussy was already wet, shaved smooth, lips puffy and glistening. I shoved two fingers in without warning. She gasped, pushing back onto them.
"Jesus, you're soaked," I growled. "You've been waiting for your son to fuck you, haven't you?"
Mom moaned, grinding on my hand. "Yes. God yes. I want that big cock inside me. Fill your mother up."
I pulled my fingers out, licked them, then dropped my shorts. My dick sprang free, thick and veined, head already leaking. I rubbed it along her slit, smearing her juices. Then I slammed in balls-deep in one thrust. She cried out, cunt clenching around me like a vice.
I fucked her hard right there, hips slapping against her ass, the sound wet and filthy. Each stroke made her tits bounce. I reached around, pinched her nipples hard through the tank. "Take it, Mom. Take your son's cock like the dirty slut you are."
She pushed back, meeting every thrust. "Harder, baby. Pound Mommy's pussy. I've been fingering myself thinking about this for months."
I grabbed her hair, yanked her head back, and railed her faster. The counter shook. Her juices ran down my balls. I could feel her getting tighter, close already. I reached down and rubbed her clit in rough circles.
"Come on my dick," I ordered. "Come for your son."
She did, screaming, pussy spasming and squirting a little around my shaft. I didn't stop. I kept pounding through her orgasm, then pulled out, spun her around, and lifted her onto the counter. Legs spread wide, I drove back in, watching her face as I fucked her deep and nasty.
Her tits spilled out when I ripped the tank down. I sucked one nipple, biting it, while my cock stretched her open. "This cunt belongs to me now," I told her between thrusts. "No more pretending."
Mom wrapped her legs around me, heels digging into my ass. "It's yours. Fuck it whenever you want. Come inside me, baby. Fill Mommy with cum."
I lost it. I buried myself to the hilt and unloaded, thick ropes of cum pumping deep into her. She milked every drop, moaning like a whore as I filled her up.
We didn't stop there. I carried her to the couch, bent her over the arm, and took her ass next, using her own cum as lube.

She begged for it, dirty and loud, telling me how much she loved her son's cock in every hole. We fucked until the sun came up, raw and relentless, no limits left between us.
By morning she was leaking my load from both holes, smiling like she'd finally gotten exactly what she needed. And I knew this was just the start.
