Caught off guard, I watch my curvaceous stepsister, her massive, round ass bouncing, as she masturbates enthusiastically in our shared bathroom. Unable to resist, I stroke myself discreetly, hoping she won't notice. But she does, and instead of shaming me, she turns the tables. Dropping to her knees, she engulfs my throbbing cock, then mounts me in a sultry reverse cowgirl, her big booty slapping against my thighs as she rides me hard.
