A young man, alone with his thoughts and hormones, finds solace in the forbidden. He retrieves a drawer full of his sister's tangas, each one a testament to her femininity. He selects a red one, tracing the thin straps, imagining them cutting into her soft flesh. His cock throbs, tenting his boxers. He frees it, the sight of the tiny panty making him ache. He rubs the head against the fabric, pre-cum soaking it. His strokes become feverish, his breath ragged. With a final groan, he releases, his semen painting the lacy thong, a testament to his taboo desire.
