Stepmother rewards me with a BJ and sex for good grades

After a grueling exam week, I finally scored top marks in all my subjects. My stepmom, who's always been strict with academics, surprised me with a reward that was anything but textbooks. She led me to the guest room, where she dropped to her knees, unzipping my pants to reveal my throbbing excitement. I gawked as this mature, voluptuous woman took me deep into her mouth, her experienced hands working magic on my manhood. The anticipation built as she stood up, revealing her ample backside. I couldn't resist plunging my throbbing member into her, driving me wild. She then mounted me, riding me like a pro, her luscious curves bouncing with each thrust. The climax came as she bent over, her derriere presented to me for one final, explosive plunge. The ultimate reward for an A+ in pleasure, leaving me with an unforgettable memory.
