Bored and restless, a young sister and brother find themselves alone, their hormones raging. Michelle, a horny teen, starts touching herself, her fingers exploring her wet pussy as she strokes her big ass. Her brother walks in on her, catching her in the act. They argue, but the tension between them is palpable. Later, they decide to masturbate together, Michelle taking in her brother's thick, straight cock as he jerks off. She fantasizes about feeling him inside her, and just as they're about to act on it, someone walks in, forcing them to stop.
