In the sultry heat of a summer afternoon, a curious young man explores his newfound desires. His eyes linger on his brother's firm ass, a sight he's seen countless times, but now with new appreciation. He tentatively touches himself, his dick hardening as he imagines the forbidden. Alone in his room, he fingers his tight hole, teasing it, before pulling out his throbbing cock and stroking it, imagining it's his brother's hand. He moans, his body tensing as he nears climax, his mind filled with the taboo image.
