I never expected to find my own mother bent over the kitchen table with her skirt hiked up and her thick cock in her fist. It was a Tuesday afternoon, and I had come home early from work. The house was quiet except for her low grunts. I stood frozen in the doorway, watching her stroke that veiny shaft, the head already slick and shiny. Her heavy balls swung beneath it as she pumped faster.
She looked up and caught me staring. Instead of stopping, she smiled. "Come here, baby. Mommy's been waiting for this."
My cock was rock hard in my jeans before I even took a step. She turned around, presenting that round ass and the fat dick hanging between her legs. "Touch it," she ordered. I reached out and wrapped my fingers around her hot meat. It was bigger than mine, pulsing in my grip. She moaned and pushed back, grinding her ass against my crotch.
"Pull it out," she said. I unzipped and let my dick spring free. She grabbed it and rubbed the heads together, smearing our precum. Then she dropped to her knees and swallowed me whole. Her mouth was wet and greedy, tongue working the underside while she stroked her own cock at the same time.
I fucked her face hard, holding her hair. She gagged but didn't pull away. When I pulled out, strings of spit connected my cock to her lips. "Fuck Mommy's ass," she begged. She bent over the table again, spreading her cheeks. Her hole was already lubed and ready. I lined up and shoved in deep. She was tight and hot, gripping me as I started pounding.
While I railed her ass, she reached down and jerked her big shemale cock. The sound of skin slapping skin filled the kitchen. "Harder, son. Fuck your shemale mom like you mean it." I slammed into her, balls deep, feeling her cock twitch in her hand. She came first, shooting thick ropes across the floor, her ass clenching around me. That pushed me over.

I unloaded deep inside her, flooding her guts with cum.
We didn't stop there. She turned around, still hard, and pushed me onto the table. "My turn," she growled. She spread my legs and pressed her slick cock against my hole. It hurt at first, but she worked it in slow, then started fucking me with the same raw rhythm. Her heavy tits bounced as she thrust. I stroked my own cock while she used me, calling me her dirty boy, her incest slut.
We spent the whole afternoon switching, sucking, and fucking in every position. She rode me on the couch, her cock slapping my stomach. I took her from behind on the stairs. By the time my dad was due home, we were both spent, covered in sweat and cum, her shemale cock finally soft against her thigh.
She kissed me deep before we cleaned up. "This is our secret now," she whispered. "And we're not done yet."
