I make my way over and run my hands through my stepsister's hair as she pleasures herself while I'm convinced to penetrate her vigorously to get her fully off. I also fill her narrow vagina with my climax

I stumble walking up on my stepsister pleasuring herself as I can’t wait to switch up and take over, pushing in hard with wild intensity until she shoots and has another orgasm inside her tightness. It became steamy reality of a taboo encounter.
