As the clock strikes midnight, the step-sister's teasing reaches a fever pitch. She grinds her ass against his hard cock, begging for him to fuck her. He spins her around, pushing her up against the cold wall, and slides his big dick deep into her tight, wet pussy. She moans, her breath fogging up in the chilly air, as he pounds her from behind. The sound of their bodies slapping together echoes through the empty house, a symphony of their forbidden lust. Just as they're about to cum together, a noise from upstairs shocks them back to reality, leaving them panting and spent, their secret safe for another night.
