I caught my stepsister masturbating with a dildo and ended up cumming inside her tight pussy

I never thought I'd walk in on my stepsister in the middle of an intense masturbation session. She was using a huge dildo, her big ass bouncing as she rode it, her big boobs heaving with every thrust. I couldn't help but watch, my big dick getting harder by the second. Before I knew it, I was joining her, and we ended up having the most passionate sex, culminating in a hot corrida dentro that left us both satisfied and breathless.
