Incestuous siblings' secret masturbation session

Tired of their daily bickering, step-siblings Michelle and her brother retreat to their respective rooms. Unbeknownst to each other, they both start to masturbate. Michelle, frustrated and horny, fingers her wet pussy while her brother strokes his thick cock, imagining his stepsister's tight body. When he catches her in the act, they argue, but their tension soon turns into mutual desire. Naked, they explore each other's bodies, Michelle's eyes widening at the sight of her brother's massive cock. Just as they're about to cross the line, a sudden noise forces them to stop, leaving them breathless and yearning.
