Tim, the family's black sheep, finds solace in his stepsister's company. One sultry afternoon, as she lounges poolside, he can't help but appreciate her sun-kissed skin. When she notices his gaze, she smiles, inviting him closer. He complies, his hands exploring her body, tracing the curve of her bustier. She moans softly, her nipples hardening against the fabric, as he slips his hand beneath her panties, finding her wet and ready for his touch.
