Engaged in a peaceful yoga session, I'm caught off guard when my stepmom enters, her gaze immediately drawn to my tented shorts. She approaches, her eyes hungry, and before I can protest, she's pulling out my throbbing cock and taking it into her mouth. She's insatiable, stripping off her dress to reveal she's not wearing any panties. Straddling me, she impales herself on my big dick, her tight pussy struggling to accommodate my size. We fuck hard and rough, her loud moans and my grunts filling the air. She cums repeatedly, each orgasm more intense than the last, her fluids coating my cock and balls. I grab her ass, slamming into her as I chase my own release, eventually filling her with my hot cum.
