I had just turned eighteen when it started, and Mom was thirty-nine, still smoking hot with that thick ass and heavy tits that bounced when she walked around the house in those thin nightgowns. We were alone after Dad left for good, stuck in that small apartment where the walls felt too close and the heat never quit. One humid Friday night I came home late from a party, half-drunk and horny as hell. She was on the couch in nothing but a short robe, legs spread just enough that I caught a glimpse of her bare pussy as she shifted.
"Lock the door, baby," she said, voice low and rough. "Come sit with me."
I dropped beside her and she didn't pull away when my thigh touched hers. Her robe slipped open and those big nipples were already hard. "You've been staring at me for months," she muttered, reaching over to grab my cock through my jeans. "Fuck, you're already stiff. You want this real mom pussy, don't you?"
I nodded, throat dry. She unzipped me fast, pulled my dick out, and wrapped her warm hand around it, stroking slow and tight. "Say it. Tell your mom what you want."
"I want to fuck you," I growled. "Right now."
She laughed dirty, leaned in, and kissed me hard, tongue pushing deep while her hand pumped faster. Then she stood, dropped the robe, and bent over the arm of the couch, ass up, pussy glistening. "Eat it first. Get your mom's cunt ready for that young cock."
I dropped to my knees and buried my face between her cheeks, licking her wet slit from clit to asshole. She tasted salty-sweet, dripping on my tongue as I sucked her swollen lips and flicked her clit. She moaned loud, pushing back on my face. "Deeper, fuck, just like that. Good boy."
When she was soaked and panting, she turned around, shoved me onto the couch, and straddled me. She grabbed my dick, rubbed the head up and down her slit, then sank down in one smooth motion. Her pussy was tight and hot, gripping every inch as she took me balls-deep. "Oh shit, that's big," she hissed. "Filling your mom up so good."
She rode me hard, tits swinging in my face. I grabbed them, sucked the nipples, biting just enough to make her yelp and grind faster. The wet sounds of her pussy slapping down on me filled the room. She leaned back, hands on my knees, and I watched my cock disappear into her over and over. "Fuck me like you mean it," she ordered.
I flipped her onto her back, hooked her legs over my shoulders, and pounded deep. She clawed my back, cursing and moaning, telling me how much better I felt than any other man. Her pussy clenched and she came hard, squirting a little around my shaft, soaking the cushions. I didn't stop.

I kept slamming until my balls tightened and I exploded inside her, pumping thick ropes of cum deep in her cunt.
We didn't talk after. She just pulled me down on top of her, both of us breathing heavy, my dick still twitching inside her. Later that night she woke me with her mouth, sucking me hard again, and we fucked on the kitchen table, then in the shower, her bent over with water running down her ass while I took her from behind. By morning we were still at it, raw and sweaty, no shame left.
It became our secret. Every night after that she came to my room or pulled me into hers. Sometimes slow and deep, sometimes rough and quick, her whispering filthy things like "Cum in your mom again" while I filled her. We never stopped. That first night just opened the door and we walked right through it.
