A stepbrother's innocent shower is disrupted by his sister's insatiable hunger. She joins him, her eyes locked onto his growing erection. "Don't be shy, brother," she purrs, taking his cock in her hand. She strokes him, her touch sending jolts of pleasure through him. Kneeling, she takes him into her mouth, savoring his taste. He tries to resist, but her skilled tongue and eager sucking push him to his limits. When she mounts him, impaling herself on his cock, he can't help but thrust into her, giving in to their forbidden desire.
