My cock too big for my teen stepsister

The teenage stepsister gasps as she takes her first glimpse of the massive cock standing at full attention. It towers over her, a intimidating pillar of flesh that seems impossible to contain. As she hesitates, her stepbrother approaches, his muscular frame casting a shadow over her petite body. With a mischievous grin, he runs his hands over her soft, youthful curves, teasing her nipples until they harden with anticipation. Despite her initial shock, a growing excitement builds within her. She reaches out hesitantly, wrapping her tiny fingers around the thick shaft. Her stepbrother groans, his hips thrusting forward as she slowly strokes, her eyes wide with a mix of fear and fascination. The room fills with the sounds of their heavy breathing, a symphony of forbidden desire that fuels their relentless pursuit of pleasure.
