A curious alarm wakes up a petite blonde teen stepsister, who finds her stepbrother already stirring with morning wood. His massive cock stretches his boxers, tenting the fabric. She tentatively approaches, her heart pounding with a mix of excitement and taboo. Kneeling before him, she wraps her tiny hand around his shaft, feeling its heat and throb. She looks up at him, her eyes wide with innocent lust, before taking him into her mouth, her tongue swirling around his head.
