Sis interrupts my solo session with her big ass and won't leave

As I\'m chilling on the couch, my step sister barges in, disrupting my solo porn session. She\'s a naughty vixen, flaunting her curves in a skimpy skirt. Despite my attempts to shoo her away, she persists, climbing on top of me. Things escalate as she strokes my hard dick, leading to a steamy encounter.
