I walked into the kitchen that night knowing exactly what I wanted. Mom was at the sink rinsing dishes, her robe hanging loose, the thin fabric clinging to her ass every time she moved. She was 48, still tight from yoga, and I was 23 with a hard-on that wouldn't quit after months of us dancing around it.
"Hey," I said, stepping up behind her.

My hands went straight to her hips. "Dad's gone for the weekend."
She didn't pull away. "I know." Her voice was low. "We can't keep doing this, baby."
I pressed my cock against her ass through my shorts. "We're not doing anything yet. But I want to fuck you tonight. For real."
Mom turned around, robe falling open. Her tits were full, nipples already stiff. She looked me in the eye and said, "Then take it."
I yanked the robe off her shoulders and let it drop. She was naked underneath. I pushed her back against the counter, dropped to my knees, and spread her legs. Her pussy was smooth, lips already wet. I buried my face between them and licked hard, dragging my tongue from her clit down to her hole and back up. She grabbed my hair and moaned loud.
"Fuck, that's it. Eat your mother's cunt."
I sucked her clit, slid two fingers inside her, and pumped them while I worked my tongue. She came fast, thighs shaking against my face, juices running down my chin. When she finished, she pulled me up and kissed me deep, tasting herself on my tongue.
"Bedroom. Now."
We didn't make it to the bedroom. She dropped to her knees right there on the kitchen floor and yanked my shorts down. My cock sprang out, thick and leaking. She wrapped her hand around it, stroked once, then took it in her mouth all the way to the base. Her throat opened for me. She gagged but didn't stop, bobbing her head, spit dripping down my balls.
I fucked her mouth, holding her head, thrusting until her eyes watered. "You like sucking your son's dick, don't you?"
She pulled off just long enough to answer. "Yes. I love it." Then she went back down, sucking harder.
I pulled her up before I came, bent her over the kitchen table, and kicked her legs apart. I rubbed the head of my cock against her wet slit, then shoved in deep in one thrust. She was tight and hot, gripping me all the way. I started pounding her, the table scraping across the floor with every slam.
"Harder," she begged. "Fuck me like you mean it."
I grabbed her hips and gave it to her, skin slapping loud, her ass rippling every time I bottomed out. She reached back and spread herself wider for me. I spit on her asshole and rubbed my thumb over it while I kept fucking her pussy.
"Do it," she said. "Put your thumb in my ass."
I pushed it in. She moaned and pushed back against me. I switched, pulling out of her cunt and pressing my cock against her asshole. It took a minute, but she relaxed and I slid inside, slow at first, then deeper. Her ass was even tighter. I fucked it steady, reaching around to rub her clit until she came again, shaking and cursing.
When I was close, I pulled out, spun her around, and pushed her to her knees again. She opened her mouth and I stroked my cock over her tongue. Thick ropes shot out, covering her lips and chin. She swallowed what she could and licked the rest off me.
We didn't stop there. We moved to the couch. She rode me reverse, ass bouncing while I watched my cock disappear into her. Later she got on all fours and I took her pussy again from behind, pulling her hair, calling her my dirty mom. She came three more times before I filled her up, pumping cum deep inside her while she begged for it.
Afterward we lay there sweaty and breathing hard. She looked at me and smiled. "We're doing this again tomorrow."
I nodded. "Every chance we get."
That was the first night. It wasn't the last.
