Masturbating while watching my stepmother's big ass

I've always had a thing for my stepmom's voluptuous derriere, and today, I decided to take matters into my own hands. Alone in the house, I found myself unable to resist the allure of her luscious backside. Unable to resist, I found myself pleasuring myself while gazing at her ample assets. As I continued to stroke, I became increasingly aroused by the sight of her plump rear. My hand moved faster as I imagined myself licking every inch of her generous curves. The thought of tonguing her tight pucker was enough to propel me over the edge, my release spilling onto the floor. The sight of my stepmom's ample ass, coupled with the intense pleasure of self-indulgence, left me weak in the knees. This is not a story about a son and his mother, but rather, an amateur lad and his mature, well-endowed stepmother. This is about lust, desire, and the irresistible allure of a mature, big-assed MILF.
