An 18-year-old virgin step-sister, her innocence evident in her nervous smile, finds herself alone with her stepbrother. As they banter, she can't help but steal glances at his thick, erect cock, tenting his shorts. She's torn between her curiosity and her virtue, until she finally gives in, pushing him onto the bed and straddling him. They lock eyes as she guides him into her tight, untouched pussy, her breath hitching as she feels him stretch her. She rides him slowly, savoring every inch, until she can't hold back anymore and they both cum hard, collapsing together in a mess of sweat and spent fluids.
