My stepsister walks in on me pleasuring myself with her lingerie and takes me roughly until I climax in her rear end

I was indulging in some solo action, wearing my stepsister's lingerie, when she unexpectedly barged in. Instead of being shocked or upset, she was aroused by the sight. She wasted no time, taking control and giving me a rough ride that left me breathless. Her voluptuous figure and ample bosom were a sight to behold as she straddled me, her eyes filled with lust. The sight of her tight, round derriere bouncing up and down was enough to send me over the edge. I couldn't resist the urge to release my pent-up desire, filling her with my essence. The thought of my father-in-law watching us only added to the excitement, turning this into a taboo experience I won't soon forget. This is a true testament to the allure of forbidden pleasures and the irresistible allure of my stepsister's body.
