The house was quiet except for the low hum of the AC when I walked into the living room and saw him standing there in nothing but gym shorts. My son, twenty-two years old, built like a fucking linebacker, with that thick bulge already pressing hard against the thin fabric. I knew what was coming. We both did.
"Lock the door, Mom," he said, voice low and rough. I did it without a word, my pussy already wet from the way his eyes dragged over my tits and down to my ass. He shoved the shorts down and that monster cock sprang out—thirteen thick inches of veiny, heavy dick, the head already leaking. It hung heavy and proud, too big for his fist to wrap all the way around.
I dropped to my knees right there on the carpet. "Give it to me," I told him, opening my mouth wide.
He stepped forward and slapped that fat cock across my tongue, then pushed in. The stretch burned in the best way. I gagged hard when he hit the back of my throat, spit running down my chin, but I kept sucking, both hands stroking the rest of that massive shaft. He tasted salty and hot, and every time I swallowed around him he groaned like he wanted to fuck my face raw.
He pulled out after a minute, strings of spit connecting my lips to his cockhead. "On the couch. Now." I climbed up, ass in the air, and he ripped my shorts down. Two thick fingers shoved straight into my cunt, checking how soaked I was. "Fucking dripping for your son's dick again," he muttered, then lined up that huge head and pushed.
The first few inches always hurt. He stretched me open slow and mean, making me feel every ridge. By the time he was halfway in I was panting, gripping the cushions. "More," I begged. He gave it to me—inch after thick inch until his heavy balls pressed against my clit and I felt him bottom out deep in my guts. Thirteen inches buried inside his own mother. I came right then, cunt pulsing around him, juices running down my thighs.
He started fucking me hard after that. Long, deep strokes that made my ass ripple every time he slammed home. The wet slap of skin on skin filled the room. "Take that big dick, Mom," he growled, one hand fisting my hair, the other smacking my ass red. "This tight pussy was made for your son's cock." I pushed back to meet every thrust, moaning like a whore, loving how he split me open.
He flipped me onto my back so he could watch my face while he wrecked me. My legs went over his shoulders and he folded me in half, pounding straight down into my cervix. I could see the outline of that monster moving inside me, bulging my lower belly. "Look at that," he said, pressing his palm there. "Feel how deep I am?" I nodded, eyes glassy, another orgasm building fast.
When he pulled out I whined, but he just flipped me again and hauled me onto his lap, impaling me on that massive cock in one drop. I rode him hard, tits bouncing, while he sucked my nipples and slapped my ass. "Gonna fill you up," he warned. I clenched around him, begging for it. He came with a roar, flooding my cunt with thick, hot spurts that leaked out around his shaft and ran down his balls.
We didn't stop there. He stayed hard—always did with that size—and bent me over the arm of the couch next, fucking me from behind until I squirted all over the floor. By the time he dumped his second load in me I was shaking, throat raw from screaming his name.
Later, lying there with his cum still leaking out of my stretched hole and his huge cock resting heavy on my thigh, I knew we'd do it again tomorrow. And the next day. That thirteen-inch dick owned me, and we both loved every filthy second of it.
