Voyeuristic siblings can't resist

Hidden away in a secret corner of the house, the siblings give in to their taboo desires. The older sister, her eyes locked onto her brother's growing erection, can't help but reach out and stroke it through his pants. He gasps, his cock twitching at her touch, and she knows she's found a weakness in his resolve. She leans in, her breath hot on his ear, and whispers, "You want to watch me, don't you?" before pulling him into a passionate, forbidden kiss.
