Uninhibited stepsister rides my cock before a romantic evening with her boyfriend

I was getting ready to go on a date with my stepsister\'s boyfriend when she barged in, eager to show off her perfect body. Overwhelmed by desire, she climbed on top of me, riding me hard and loud. Her natural tits bouncing, her wet pussy taking every inch, and her big ass swaying in rhythm. The climax was explosive, leaving us both moaning in pleasure.
