Dad remarried so I had another stepmother. It happened so suddenly that I still couldn't accept this stepmother right away. I have never called my stepmother "mom" before. Today my father goes on a business trip for about a week. After preparing breakfast for me, my mother took the opportunity to fold clothes. Mom's big butt kept curling up before my eyes, making it impossible for me to look away. A while later, while going to the toilet, I suddenly saw my mother's underwear!!! It turned out that my mother was cleaning the bathtub. She didn't know how but it got all wet, so she took off her pants and underwear and threw them out. Looking at my mom's chubby pussy made me completely lose my mind! I rushed forward to hug this big round butt! Spread her ass and put my cock inside! Even though she couldn't speak with her mouth, she was still happy and had orgasms over and over again. And after just a few times of making love together, Mom completely erased her shyness and proactively came to me, seduced me and wanted me to make her even more happy!!!
