Unbeknownst to you, your stepmom has been listening to your late-night porn marathon. Drawn by the sounds, she enters your room, finding you sprawled on your bed, hand furiously pumping your hard cock. She gasps, seeing your massive, veined member glistening with pre-cum. Transfixed, she watches you pleasure yourself, your ass cheeks clenching with each thrust. You notice her, your pace quickening, your breath ragged. She bites her lip, her eyes never leaving your cock as you grip it tighter, faster, until with a grunt, you come undone, ropes of cum painting your chest and hand, leaving your stepmom flushed and flustered.
