In the solitude of his room, a young man discovers the pleasure of his own touch. His large cock, straining against his pants, demands release. He frees it, gasping at the sensation of his hand sliding up and down the length. His mind fills with images of his sister, her innocent face, her petite body. He imagines her delicate fingers gripping his shaft, her virgin pussy dripping with anticipation. The intensity of his fantasy propels him to the edge, his body tensing as he spills his load, his mind a whirlwind of taboo desires.
