The house was quiet except for the low hum of the fridge and the occasional creak of old floorboards. I stood in the kitchen doorway watching my mom, Linda, bent over the counter in nothing but a thin tank top and panties. She was 48, still thick in the hips and ass, with heavy tits that strained the fabric. I was 25, home for the summer, and we had crossed the line three nights ago. Now there was no going back.
She straightened up and turned, catching me staring. "You gonna just stand there or come help me with these dishes?" Her voice was husky, already knowing the answer. I crossed the room, pressed my body against her back, and slid my hands under her tank top to grab those big tits. Her nipples were already hard.
"Fuck, Mom," I muttered against her neck. "You been waiting for this all day?"
She pushed her ass back against my hardening cock. "Since you fucked me on the couch last night. Couldn't stop thinking about your dick inside me." She reached back and rubbed me through my shorts. "Take it out. I want it raw again."
I yanked my shorts down. My cock sprang free, thick and already leaking. She wrapped her fingers around it and stroked slow, twisting her wrist the way she knew I liked. "Always so fucking hard for your mother," she said, voice low and dirty. "You like that taboo shit, don't you? Your own mom jerking you off in the kitchen."
I pulled her panties down and kicked them aside. Her pussy was shaved smooth and already wet. I ran two fingers along her slit, then shoved them inside. She moaned and spread her legs wider. "Yeah, finger that cunt. Get it ready for your cock."
She bent forward over the counter again. I lined up and pushed in deep in one thrust. She was tight and hot, gripping me like she never wanted me to pull out. I started fucking her hard, skin slapping, the counter digging into her thighs. Every stroke made her tits bounce under the tank top.
"Harder," she gasped. "Fuck your mom like you mean it. Fill me up."
I grabbed her hips and slammed into her, balls deep, over and over. The wet sounds of her pussy taking me were loud in the quiet house. She reached down and rubbed her clit while I pounded her. "I'm gonna come on my son's cock," she panted. "Don't stop. Don't you fucking stop."
Her walls clenched and she came hard, shaking, a long moan ripping out of her. I kept thrusting through it until I felt my own orgasm building. "Where do you want it, Mom?"
"Inside. Always inside. Breed that pussy."
I buried myself to the hilt and unloaded, pumping thick ropes of cum deep into her. She milked every drop, pushing back against me until I was empty. When I finally pulled out, my cum leaked down her thigh. She turned around, scooped some up with her fingers, and licked them clean while looking me in the eyes.
"Bedroom," she said. "We're not done."
Upstairs, she stripped completely and lay back on the bed, legs spread. Her pussy glistened with my load. I climbed between her thighs and licked her clean, tasting my own cum mixed with her juices. She held my head and ground against my mouth. "That's it. Eat Mommy's cunt. Make me come again."
I sucked her clit and slid three fingers inside her. She came fast, thighs clamping around my head. Before she finished shaking I moved up and slid my cock back into her. We fucked slower this time, deep and grinding, her legs wrapped around me. She whispered filthy things the whole time—how she loved her son's dick, how she wanted to wake up with it in her mouth, how she'd let me fuck her anywhere in the house.
I rolled us so she was on top. She rode me hard, tits bouncing, hands on my chest. "Look at you," she said. "Fucking your own mother like a little pervert. You love it." I reached up and pinched her nipples. She moaned louder and bounced faster until she came again, soaking my cock.
We switched positions all night. I took her from behind again, then on her side, then with her legs over my shoulders so I could go even deeper.

Every time I came she begged for it inside. By morning we were both sore and sticky, sheets ruined.
She kissed me slow before we finally slept. "This is ours now," she whispered. "No one else needs to know. Just you and me and this dirty secret."
I pulled her closer, already getting hard again against her thigh. She smiled and reached down to stroke me. "Round four?"
The sun was coming up, but neither of us cared. We had all day, all summer, and every taboo night after that.
