In the throes of summer heat, a young man's curiosity leads him to the forbidden fruit of his stepbrother's underwear. He discovers the garment, damp and clinging to his brother's scent, in the laundry basket. Intrigued, he takes it to the poolside, the sun baking his skin as he explores the fabric's texture. His cock hardens, tenting his shorts, as he imagines his brother's body, the taste of his cock, the feel of it sliding into his eager mouth. He jerks off slowly, savoring the taboo, until he reaches the brink, his body tensing as he spills his load onto the concrete, the evidence of his forbidden desire glistening in the sunlight.
