I walked into the kitchen after midnight and there she was, leaning against the counter in nothing but a thin tank top and panties. Mom looked up from her glass of wine, her eyes already dark. "Couldn't sleep either?" she asked, voice low.
I shook my head. She set the glass down and stepped closer. Her nipples were hard under the cotton. "You've been staring at me all week," she said. "I know what you want."
My cock was already stiffening in my shorts. She noticed and smiled that dirty little smile. "Show me."
I pushed my shorts down. My dick sprang out, thick and ready. Mom licked her lips, reached out, and wrapped her fingers around it. "Fuck, you're bigger than I thought," she muttered. She stroked me slow at first, then tighter, her thumb rubbing over the head.
She dropped to her knees right there on the kitchen floor. Her mouth opened and she took me in, hot and wet. She sucked hard, cheeks hollowing, tongue swirling under the shaft. I groaned and grabbed her hair. She moaned around my cock like she loved it, saliva dripping down her chin onto her tits.
After a minute she stood up, shoved her panties down, and bent over the counter. "Fuck me," she said. "Hard."
I stepped behind her, lined up, and slammed in. Her pussy was soaked, tight, gripping me. I pounded her, the sound of skin slapping filling the room. Mom pushed back against every thrust, moaning loud. "That's it, fuck your mother. Give it to me."
I reached around and rubbed her clit while I fucked her. She came quick, pussy clenching, juices running down her thighs. I didn't stop. I kept driving into her until my balls tightened and I shot deep inside her, pumping load after load.
We didn't talk much after. She just turned around, kissed me messy, and whispered, "My room. Now."
We moved to her bed. She stripped the rest of the way and lay back, legs spread. "Eat me," she ordered. I buried my face between her thighs, licking her swollen clit, tasting my cum mixed with her cream. She grabbed my hair and ground against my mouth until she came again, thighs shaking.
Then she pushed me onto my back and climbed on. She sank down on my cock, riding me slow and deep, her heavy tits bouncing. I reached up and squeezed them, pinching her nipples. She leaned forward so I could suck one, biting gently while she rocked her hips.
We switched positions a few times. Doggy again, her ass up high. Then her on top facing away so I could watch my cock disappear into her. Every time she talked dirty. "Fill me up again. I want your cum leaking out of me all night."
I came twice more before we finally collapsed, sweaty and spent. She curled against me, one hand still lazily stroking my softening dick. "This is just the start," she said. "Tomorrow night you're fucking me in the shower."
I was already getting hard again. Mom noticed and laughed softly. "Insatiable. Just like your father." She slid down and took me in her mouth once more, sucking me back to full strength while her fingers played with my balls.
We didn't sleep much that night. Every time one of us stirred, the other reached out. Hands, mouths, my cock sliding back into her wet heat. By morning we were both sore and sticky, but satisfied in a way that made us both smile when the sun came up.
Mom kissed my chest and whispered, "Same time tomorrow?" I nodded.

This was our secret now, raw and real and exactly what we both needed.
